本申請案涉及聲學技術領域，特別涉及振動組件及揚聲器。 This application relates to the field of acoustic technology, in particular to vibration components and speakers.
本申請主張於2021年11月26日提交之申請號為2021114247989的中國專利申請案的優先權，其全部內容通過引用的方式併入本文。 This application claims priority to the Chinese patent application No. 2021114247989 filed on November 26, 2021, the entire contents of which are incorporated herein by reference.
揚聲器通過振膜推動空氣振動，從而產生聲音。對於小尺寸的MEMS揚聲器或微型揚聲器，由於其尺寸為毫米量級，因而振膜的尺寸大幅度縮小，推動空氣量少，會使得小尺寸的MEMS揚聲器或微型揚聲器的低頻靈敏度不高。 The speaker produces sound by pushing the air to vibrate through the diaphragm. For small-sized MEMS speakers or miniature speakers, since their size is in the millimeter range, the size of the diaphragm is greatly reduced, and the amount of air pushed is small, which will make the low-frequency sensitivity of small-sized MEMS speakers or miniature speakers not high.
因此，有必要提出一種振動組件，以提高揚聲器(尤其是小尺寸揚聲器)的低頻性能。 Therefore, it is necessary to propose a vibration component to improve the low-frequency performance of a speaker (especially a small-sized speaker).

本說明書一些實施例中提供了一種振動組件。振動組件可以回應於機械振動(如驅動單元的機械振動)而產生振動。在一些實施例中，振動組件可以設置於揚聲器中，振動組件可以在驅動單元的作用下進行振動，並通過揚聲器的殼體上的孔部將振動產生的氣導聲音訊號傳遞至揚聲器的外部。在一些實施例中，振動組件可以包括彈性元件和支撐元件，支撐元件與彈性元件連接，並支撐彈性元件。在一些實施例中，彈性元件可以包括增強區域、一個或多個預處理區域和固定區域，其中，增強區域可以設置於彈性元件的中部，一個或多個預處理區域環繞設置於增強區域的週邊，固定區域環繞設置於一個或多個預處理區域週邊。支撐元件與彈性元件的固定區域連接。在一些實施例中，支撐元件可以位於固定區域沿增強區域的振動方向的任一表面，並與固定區域連接。在一些實施例中，在彈性元件振動時，一個或多個預處理區域可以為增強區域提供沿增強區域的振動方向的一個或多個位移量。在一些實施例中，一個或多個預處理區域為增強區域提供的振動位移或振動幅度由該一個或多個預處理區域提供的沿增強區域的振動方向的一個或多個位移量疊加而成。預處理區域可以是彈性元件上經過預先處理的區域，該預處理區域相比於彈性元件上的其他區域(未進行預先處理的區域)具有更強的變形能力。在一些實施例中，預先處理的手段可以包括但不限於折彎、改變材料硬度等。由於一個或多個預處理區域具有比彈性元件上的其他區域更強的變形能力，因此，設置一個或多個預處理區域可以提高增強區域沿其振動方向的總位移量，即可以提高增強區域的振動位移或振動幅度。在一些實施例中，彈性元件可以包括第一預處理區 域，第一預處理區域為增強區域提供沿增強區域的振動方向的第一位移量。增強區域的振動方向的第一位移量可以是第一預處理區域為增強區域在其振動方向上的振動過程中所貢獻的位移大小。在一些實施例中，彈性元件還可以包括第二預處理區域，第二預處理區域為增強區域提供沿增強區域的振動方向的第二位移量。增強區域的振動方向的第二位移量可以是第二預處理區域為增強區域在其振動方向上的振動過程中所貢獻的位移大小。在一些實施例中，一個或多個預處理區域可以包括一個或多個折環(例如，第一折環、第二折環等)，一個或多個折環在受到振動時產生形變，折環受到振動產生的形變量大於未進行預處理的彈性元件(非折環)受到振動產生的形變量，從而提高在彈性元件振動時，增強區域在其振動方向上的振動位移或振動幅度，從而達到提高振動組件回應的靈敏度。 In some embodiments of the present specification, a vibration assembly is provided. The vibration assembly can generate vibration in response to mechanical vibration (such as mechanical vibration of a drive unit). In some embodiments, the vibration assembly can be arranged in a loudspeaker, and the vibration assembly can vibrate under the action of the drive unit, and transmit the air-conducted sound signal generated by the vibration to the outside of the loudspeaker through the hole on the housing of the loudspeaker. In some embodiments, the vibration assembly can include an elastic element and a supporting element, and the supporting element is connected to the elastic element and supports the elastic element. In some embodiments, the elastic element may include an enhanced region, one or more pre-processed regions and a fixed region, wherein the enhanced region may be arranged in the middle of the elastic element, one or more pre-processed regions may be arranged around the enhanced region, and the fixed region may be arranged around the one or more pre-processed regions. The support element is connected to the fixed region of the elastic element. In some embodiments, the support element may be located on any surface of the fixed region along the vibration direction of the enhanced region and connected to the fixed region. In some embodiments, when the elastic element vibrates, one or more pre-processed regions may provide the enhanced region with one or more displacements along the vibration direction of the enhanced region. In some embodiments, the vibration displacement or vibration amplitude provided by one or more pre-processed regions for the enhanced region is formed by the superposition of one or more displacements provided by the one or more pre-processed regions along the vibration direction of the enhanced region. The pre-processed region may be a pre-processed region on the elastic element, and the pre-processed region has a stronger deformation ability than other regions on the elastic element (regions that have not been pre-processed). In some embodiments, the means of pre-processing may include but are not limited to bending, changing the hardness of the material, etc. Since one or more pre-processed regions have a stronger deformation ability than other regions on the elastic element, setting one or more pre-processed regions can increase the total displacement of the enhanced region along its vibration direction, that is, the vibration displacement or vibration amplitude of the enhanced region can be increased. In some embodiments, the elastic element may include a first pre-processed region, which provides the enhanced region with a first displacement along the vibration direction of the enhanced region. The first displacement in the vibration direction of the enhanced region may be the displacement contributed by the first pre-processed region to the enhanced region during the vibration of the enhanced region in the vibration direction. In some embodiments, the elastic element may further include a second pre-processed region, which provides the enhanced region with a second displacement along the vibration direction of the enhanced region. The second displacement in the vibration direction of the enhanced region may be the displacement contributed by the second pre-processed region to the enhanced region during the vibration of the enhanced region in the vibration direction. In some embodiments, one or more pre-processed regions may include one or more folds (e.g., a first fold, a second fold, etc.), and one or more folds are deformed when subjected to vibration, and the deformation amount of the folds subjected to vibration is greater than the deformation amount of the elastic element (non-fold) subjected to vibration without pre-processing, thereby increasing the vibration displacement or vibration amplitude of the enhanced region in its vibration direction when the elastic element vibrates, thereby achieving the purpose of improving the sensitivity of the vibration component response.
在一些實施例中，振動組件應用於揚聲器時，彈性元件的一個或多個預處理區域(例如，折環)可以提高增強區域在其振動方向上的振動位移或振動幅度，從而可以推動更多的空氣振動，進而提高揚聲器的低頻性能(如靈敏度)。並且，通過在彈性元件上設置一個或多個預處理區域(如折環)以提高彈性元件的形變能力，使彈性元件在增強區域的振動方向上具有更大的可變形量，使得振動組件在振動幅度較大時，一個或多個預處理區域可以通過變形將振動衝擊所產生的應力分散於一個或多個預處理區域內部，防止彈性元件產生應力集中，避免振動組件(尤其是彈性元件)在振動幅度較大時損壞，提高揚聲器的可靠性。 In some embodiments, when the vibration assembly is applied to a speaker, one or more pre-processed areas (e.g., folds) of the elastic element can increase the vibration displacement or vibration amplitude of the enhanced area in its vibration direction, thereby driving more air vibrations and thereby improving the low-frequency performance (e.g., sensitivity) of the speaker. Furthermore, by providing one or more pre-processed areas (such as folds) on the elastic element to improve the deformation capacity of the elastic element, the elastic element has a larger deformable amount in the vibration direction of the enhanced area, so that when the vibration component has a large vibration amplitude, one or more pre-processed areas can disperse the stress generated by the vibration impact inside one or more pre-processed areas through deformation, thereby preventing the elastic element from generating stress concentration, avoiding damage to the vibration component (especially the elastic element) when the vibration amplitude is large, and improving the reliability of the speaker.

在一些實施例中，彈性元件110沿增強區域的振動方向的投影可以為圓形、矩形、五邊形、六邊形等規則和/或不規則多邊形。
In some embodiments, the projection of the
在一些實施例中，彈性元件110沿增強區域的振動方向的投影為矩形時，可以設置彈性元件110沿增強區域的振動方向的投影尺寸(如長度、寬度)在合適範圍內，以保證振動組件100的性能。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為矩形，且矩形的長度可以為4mm至12mm。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為矩形，且矩形的長度可以為5mm至10mm。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為矩形，且矩形的寬度可以為4mm至10mm。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為矩形，且矩形的寬度可以為5mm至8mm。
In some embodiments, when the projection of the
在一些實施例中，彈性元件110沿增強區域的振動方向的投影為圓形時，可以設置彈性元件110沿增強區域的振動方向的投影尺寸(如直徑)在合適範圍內，以保證振動組件100的性能。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為圓形，且圓形的直徑可以為4mm至12mm。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為圓形，且圓形的直徑可以為5mm至10mm。
In some embodiments, when the projection of the
在一些實施例中，彈性元件110沿增強區域的振動方向的投影為多邊形時，可以設置彈性元件110沿增強區域的振動方向的投影尺寸(如多邊形外接圓直徑)在合適範圍內，以保證振動組件100的性能。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為多邊形，且多邊形的外接圓直徑可以為4mm至12mm。在一些實施例中，彈性元件110沿增強區域的振動方向的投影為多邊形，且多邊形的外接圓直徑可以為5mm至10mm。
In some embodiments, when the projection of the
在一些實施例中，對於不同形狀的彈性元件110(即彈性元件110沿增強區域的振動方向具有不同的投影形狀)，可以設置彈性元件110沿增強區
域的振動方向的厚度在合適範圍內，以保證振動組件100的性能。在一些實施例中，彈性元件110沿增強區域的振動方向的厚度可以為0.2mm至1mm。在一些實施例中，彈性元件110沿增強區域的振動方向的厚度可以為0.3mm至0.7mm。
In some embodiments, for
在一些實施例中，彈性元件110可以包括增強區域、第一預處理區域和固定區域，其中，增強區域可以位於彈性元件110的中部，第一預處理區域環繞設置於增強區域的週邊，為增強區域提供沿增強區域的振動方向的第一位移量。固定區域環繞設置於第一預處理區域的週邊，固定區域與支撐元件120連接。
In some embodiments, the
第一預處理區域可以是彈性元件上經過預先處理的區域。在一些實施例中，預先處理可以是改變材料硬度。在一些實施例中，第一預處理區域可以是彈性元件110上硬度低於其他部分的區域。由於第一預處理區域的硬度低於彈性元件110上的其他部分，因此，在彈性元件110振動時，第一預處理區域更易發生變形，從而使第一預處理區域產生的形變量可以大於彈性元件110上預處理區域(如第一預處理區域)以外的其他區域產生的形變量，進而提高第一區域處理區域為增強區域提供的沿增強區域的振動方向的第一位移量，進而提高增強區域的振動幅度或振動位移，進一步提高振動組件100的低頻靈敏度。並且，由於第一預處理區域更易發生變形，因此，在彈性元件110振動過程中，第一預處理區域中產生的應力更易分散在整個第一預處理區域中，從而可以避免在某些特定位置(如固定區域與支撐元件120的連接位置)出現應力集中的情況，防止彈性元件110損壞。
The first pre-processed area may be an area on the elastic element that has been pre-processed. In some embodiments, the pre-processing may be to change the hardness of the material. In some embodiments, the first pre-processed area may be an area on the
在一些實施例中，預先處理可以是折彎。在一些實施例中，第一預處理區域可以包括第一折環。折環可以是相對於連接第一預處理區域兩端的平面具有突出於該平面的折彎部分的結構。第一折環在彈性元件110振動時會產生形變，第一折環的折彎部分在振動過程中存在變直的趨勢，從而使第一折環
產生的形變量可以大於非折環區域(即彈性元件110上折環區域(如第一折環區域)以外的其他區域)產生的形變量，進而提高第一預處理區域為增強區域提供的沿增強區域的振動方向的第一位移量。在一些實施例中，第一折環在振動過程中發生變形後的尺寸對應於增強區域的振動方向的分量即為第一位移量。由於在彈性元件110振動過程中，第一折環可以通過折彎部分的變直趨勢產生更大的變形量，因此，第一折環可以使第一預處理區域中產生的應力更易分散在第一折環上，從而可以避免在某些特定位置出現應力集中的情況，防止彈性元件110損壞。
In some embodiments, the pre-processing may be bending. In some embodiments, the first pre-processing area may include a first fold. The fold may be a structure having a folded portion protruding from a plane connecting two ends of the first pre-processing area. The first fold will be deformed when the
由於預處理區域相對於彈性元件110的其他區域更易發生變形，通過設置第一預處理區域，可以減小彈性元件110的總剛度，提高振動組件100的順性，當彈性元件110的品質不變時，可以使振動組件100的共振峰f0前移(即，向低頻移動)，從而提高振動組件100的低頻靈敏度。
Since the pre-processed area is more prone to deformation than other areas of the
在一些實施例中，第一折環在平行於增強區域的振動方向的截面上的截面形狀可以包括但不限於圓弧狀、橢圓弧狀、折線狀、尖齒狀、方齒狀中的一種或多種。 In some embodiments, the cross-sectional shape of the first fold in the cross section parallel to the vibration direction of the enhanced region may include but is not limited to one or more of a circular arc, an elliptical arc, a broken line, a sharp tooth, and a square tooth.
在一些實施例中，第一折環可以具有第一彎折方向。第一彎折方向可以是在任意平行於增強區域的振動方向的投影面上，垂直於連接第一折環兩端的線段，且朝向突出於該平面的折彎部分的方向。在一些實施例中，當第一折環在平行於增強區域的振動方向的投影面上的截面形狀為圓弧狀時，第一彎折方向可以是垂直於連接該圓弧的兩端點的直線所朝向的圓弧凸起部分(即折彎部分)的方向。在一些實施例中，第一彎折方向與增強區域的振動方向可以平行。在一些實施例中，第一彎折方向與增強區域的振動方向可以垂直。在一些實施例中，第一彎折方向與增強區域的振動方向可以呈第一夾角。關於第一預處理區域的更多內容可以參考本說明書圖2至圖6，及其相關描述。 In some embodiments, the first fold ring may have a first bending direction. The first bending direction may be a direction perpendicular to the line segment connecting the two ends of the first fold ring and toward the bending portion protruding from the plane on any projection plane parallel to the vibration direction of the enhanced region. In some embodiments, when the cross-sectional shape of the first fold ring on the projection plane parallel to the vibration direction of the enhanced region is an arc, the first bending direction may be a direction perpendicular to the protruding portion of the arc (i.e., the bending portion) toward which the straight line connecting the two end points of the arc is directed. In some embodiments, the first bending direction may be parallel to the vibration direction of the enhanced region. In some embodiments, the first bending direction may be perpendicular to the vibration direction of the enhanced region. In some embodiments, the first bending direction may be at a first angle to the vibration direction of the enhanced region. For more information about the first pre-processing area, please refer to Figures 2 to 6 of this manual and their related descriptions.
在一些實施例中，彈性元件110還可以包括第二預處理區域，第二預處理區域環繞設置於第一預處理區域的週邊。在一些實施例中，第二預處理區域與第一預處理區域可以直接連接，即，第二預處理區域與第一預處理區域之間的間距為零。在一些實施例中，第二預處理區域與第一預處理區域也可以間隔設置，即，第二預處理區域與第一預處理區域之間具有預設的間距(如10微米、100微米等)。在一些實施例中，第二預處理區域可以為增強區域提供沿增強區域的振動方向的第二位移量。第二位移量可以是第二預處理區域為增強區域在其振動方向上的振動過程中所貢獻的位移大小。
In some embodiments, the
在一些實施例中，第二預處理區域可以是彈性元件上的第一預處理區域之外的另一經過預先處理的區域，因此，在彈性元件110振動時，第二預處理區域產生的形變量可以大於彈性元件110上預處理區域(如，第一預處理和第二預處理區域)以外的其他區域產生的形變量。在一些實施例中，第二預處理區域可以具有與第一預處理區域相類似的結構。
In some embodiments, the second pre-processed area may be another pre-processed area on the elastic element other than the first pre-processed area, so when the
在一些實施例中，第二預處理區域可以包括第二折環。第二折環在彈性元件110振動時會產生形變，第二折環的折彎部分在振動過程中存在變直的趨勢，從而使第二折環產生的形變量可以大於非折環區域產生的形變量，進而提高第二預處理區域為增強區域提供的沿增強區域的振動方向的第二位移量。第二折環在振動過程中發生變形後的尺寸在增強區域的振動方向的分量即為第二位移量。在一些實施例中，第二折環在平行於增強區域的振動方向的截面上的截面形狀可以包括但不限於圓弧狀、橢圓弧狀、折線狀、尖齒狀、方齒狀中的一種或多種。
In some embodiments, the second pre-processed area may include a second fold. The second fold will be deformed when the
在一些實施例中，第二折環可以具有第二彎折方向。第二彎折方向可以是在任意平行於增強區域的振動方向的投影面上，垂直於連接第二折環兩端的線段，且朝向突出於該平面的折彎部分的方向。在一些實施例中，第二 彎折方向與第一彎折方向可以相同或不同(例如，相反、垂直等)。第二彎折方向與第一彎折方向相反是指第一折環的折彎部分突出的方向與第二折環的折彎部分突出的方向在同一平面內朝向相反。在一些實施例中，當第一折環和第二折環為平滑曲線(曲率不等於0，且曲線的一階導數連續)時，第一折環上任一點對應的曲率中心和第二折環上任一點對應的曲率中心分別位於彈性元件的兩側，則第二彎折方向與第一彎折方向相反。在一些實施例中，關於第二預處理區域的更多內容可以參考本說明書圖7至圖18，及其相關描述。 In some embodiments, the second fold may have a second bending direction. The second bending direction may be perpendicular to the line segment connecting the two ends of the second fold and toward the direction of the bending portion protruding from the plane on any projection plane parallel to the vibration direction of the enhancement region. In some embodiments, the second bending direction may be the same as or different from the first bending direction (e.g., opposite, perpendicular, etc.). The second bending direction is opposite to the first bending direction, which means that the direction in which the bending portion of the first fold protrudes is opposite to the direction in which the bending portion of the second fold protrudes in the same plane. In some embodiments, when the first fold loop and the second fold loop are smooth curves (the curvature is not equal to 0, and the first-order derivative of the curve is continuous), the center of curvature corresponding to any point on the first fold loop and the center of curvature corresponding to any point on the second fold loop are respectively located on both sides of the elastic element, and the second bending direction is opposite to the first bending direction. In some embodiments, more information about the second pre-processing area can be referred to Figures 7 to 18 of this manual, and related descriptions.
在一些實施例中，彈性元件110還可以包括非預處理區域。在一些實施例中，當第一預處理區域和第二預處理區域間隔設置時，連接第一預處理區域和第二預處理區域之間的區域可以是非預處理區域。在一些實施例中，當第一預處理區域和增強區域間隔設置時，連接第一預處理區域和增強區域之間的區域可以是非預處理區域。在一些實施例中，在彈性元件110振動時，非預處理區域也能夠發生變形從而為增強區域的振動位移或振動幅度提供位移量。在一些實施例中，非預處理區域的變形量取決於彈性元件110的材料本身的參數(如楊氏模數)，其在彈性元件110振動時提供的位移量遠小於第一位移量或第二位移量。在一些實施例中，當增強區域、第一預處理區域和第二預處理區域之間均直接連接時(非間隔設置)，彈性元件110也可以不包括非預處理區域。
In some embodiments, the
在一些實施例中，振動組件100可以包括支撐元件120。支撐元件120可以與彈性元件110的固定區域連接。在一些實施例中，支撐元件120可以包括夾持部和形變部。夾持部與形變部可以相對設置，並分別位於彈性元件110的固定區域沿增強區域的振動方向的兩個表面，使得固定區域夾持於支撐元件120的夾持部和形變部之間。在一些實施例中，支撐元件120也可以不包括夾持部，此時形變部可以設置於彈性元件110的固定區域沿增強區域的振動方向的任一表面，並與固定區域連接(如黏接)。在一些實施例中，支撐元件120(例如，
形變部)在沿增強區域的振動方向可拉伸，從而在彈性元件110振動時通過拉伸變形為增強區域提供沿增強區域的振動方向的第三位移量。第三位移量可以是支撐元件120為增強區域在其振動方向上的振動過程中所貢獻的位移大小。
In some embodiments, the
在一些實施例中，支撐元件120的材質可以是剛性材料、半導體材料、有機高分子材料、膠類材料等中的一種或多種。在一些實施例中，剛性材料可以包括但不限於金屬材料、合金材料等。半導體材料可以包括但不限於矽、二氧化矽、氮化矽、碳化矽等中的一種或多種。有機高分子材料可以包括但不限於聚醯亞胺(PI)、派瑞林(Parylene)、聚二甲基矽氧烷(Polydimethylsiloxane，PDMS)、水凝膠等中的一種或多種。膠類材料可以包括但不限於凝膠類、有機矽膠、丙烯酸類、聚氨酯類、橡膠類、環氧類、熱熔類、光固化類等中的一種或多種。在一些實施例中，為了增強支撐元件120與彈性元件110之間的連接力，提高支撐元件120與彈性元件110之間的可靠性，支撐元件120的材質可以是有機矽黏接類膠水、有機矽密封類膠水等。在一些實施例中，支撐元件120在平行於增強區域的振動方向的截面上的截面形狀可以是長方形、圓形、橢圓形、五邊形等規則和/或不規則幾何形狀。同時通過設置柔性支撐元件120，避免彈性元件110直接與殼體接觸，減小彈性元件110直接與殼體連接端應力集中(殼體一般為剛性體)，從而進一步保護彈性元件110。
In some embodiments, the material of the
在一些實施例中，可以根據振動組件100的需求(如振動組件100的整體尺寸、增強區域在其振動方向的振動位移或振動幅度的大小)，合理的設置支撐元件120沿增強區域的振動方向的高度。在一些實施例中，支撐元件120的形變部沿增強區域的振動方向的高度可以為50μm至1000μm。在一些實施例中，支撐元件120的形變部沿增強區域的振動方向的高度可以為100μm至800μm。
In some embodiments, the height of the
在一些實施例中，支撐元件120在垂直於增強區域的振動方向的橫截面沿增強區域的振動方向可以具有不同的截面面積。例如，支撐元件120在
垂直於增強區域的振動方向，且靠近增強區域的側面(也稱為支撐元件120的內側面)上可以設置彎曲結構，使得支撐元件120的內側面的截面面積大於支撐元件120的外側面(支撐元件120在垂直於增強區域的振動方向，且遠離增強區域的側面)的截面面積。
In some embodiments, the cross-section of the
在一些實施例中，支撐元件120在回應於彈性元件110的振動訊號時可以產生形變，為增強區域提供沿增強區域的振動方向的第三位移量，從而提高增強區域在其振動方向上產生的總位移量，進一步提高振動組件100的低頻靈敏度。關於支撐元件120的更多內容可以參考本說明書圖19至圖28，及其相關描述。
In some embodiments, the
圖2至圖6是根據本說明書的一些實施例所示的振動組件示例性結構圖。 Figures 2 to 6 are exemplary structural diagrams of vibration components according to some embodiments of this specification.
如圖2所示，振動組件200可以包括彈性元件210和支撐元件220。在一些實施例中，彈性元件210可以包括增強區域211、第一預處理區域212和固定區域213。其中，增強區域211可以位於彈性元件210的中部，第一預處理區域212環繞設置於增強區域211的週邊，固定區域213環繞設置於第一預處理區域212的週邊。支撐元件220通過固定區域213與彈性元件210連接。 As shown in FIG. 2 , the vibration assembly 200 may include an elastic element 210 and a supporting element 220. In some embodiments, the elastic element 210 may include a reinforcing region 211, a first pre-processing region 212, and a fixing region 213. The reinforcing region 211 may be located in the middle of the elastic element 210, the first pre-processing region 212 may be disposed around the reinforcing region 211, and the fixing region 213 may be disposed around the first pre-processing region 212. The supporting element 220 is connected to the elastic element 210 through the fixing region 213.
在一些實施例中，彈性元件210振動過程中，第一預處理區域212可以沿增強區域211的振動方向產生一定程度的形變，從而為增強區域211提供沿增強區域211的振動方向的第一位移量，進而增加增強區域211在其振動方向上產生的位移量。 In some embodiments, during the vibration of the elastic element 210, the first pre-processed region 212 may generate a certain degree of deformation along the vibration direction of the enhanced region 211, thereby providing the enhanced region 211 with a first displacement along the vibration direction of the enhanced region 211, thereby increasing the displacement of the enhanced region 211 in its vibration direction.
在一些實施例中，彈性元件210和增強區域211沿增強區域211的振動方向的投影可以為圓形、矩形、帶圓角的矩形、五邊形、六邊形等規則和/或不規則多邊形。彈性元件210的第一預處理區域212和固定區域213沿增強區域211的振動方向的投影可以是與圓形、矩形、五邊形、六邊形等規則和/或不規則 多邊形對應的圓環、矩形環、五邊形環、六邊形環等規則和/或不規則多邊形環。 In some embodiments, the projections of the elastic element 210 and the enhanced region 211 along the vibration direction of the enhanced region 211 may be regular and/or irregular polygons such as circles, rectangles, rectangles with rounded corners, pentagons, hexagons, etc. The projections of the first pre-processed region 212 and the fixed region 213 of the elastic element 210 along the vibration direction of the enhanced region 211 may be regular and/or irregular polygonal rings such as circular rings, rectangular rings, pentagonal rings, hexagonal rings, etc. corresponding to regular and/or irregular polygons such as circles, rectangles, pentagons, hexagons, etc.
在一些實施例中，對於不同形狀的增強區域211，增強區域211可以具有不同的尺寸。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為矩形時，矩形的長度可以為2.5mm至8mm。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為矩形，且矩形的長度可以為3mm至6mm。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為矩形時，增強區域211沿增強區域211的振動方向的投影矩形的寬度可以為1mm至6mm。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為矩形，且矩形的寬度可以為2mm至5mm。 In some embodiments, for different shapes of the enhancement area 211, the enhancement area 211 may have different sizes. In some embodiments, when the projection of the enhancement area 211 along the vibration direction of the enhancement area 211 is a rectangle, the length of the rectangle may be 2.5mm to 8mm. In some embodiments, the projection of the enhancement area 211 along the vibration direction of the enhancement area 211 is a rectangle, and the length of the rectangle may be 3mm to 6mm. In some embodiments, when the projection of the enhancement area 211 along the vibration direction of the enhancement area 211 is a rectangle, the width of the projection rectangle of the enhancement area 211 along the vibration direction of the enhancement area 211 may be 1mm to 6mm. In some embodiments, the projection of the enhancement area 211 along the vibration direction of the enhancement area 211 is a rectangle, and the width of the rectangle may be 2mm to 5mm.
在一些實施例中，增強區域211沿增強區域211的振動方向的投影為圓形時，圓形的直徑可以為2mm至10mm。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為圓形，且圓形的直徑可以為3mm至8mm。 In some embodiments, when the projection of the enhanced region 211 along the vibration direction of the enhanced region 211 is a circle, the diameter of the circle may be 2 mm to 10 mm. In some embodiments, the projection of the enhanced region 211 along the vibration direction of the enhanced region 211 is a circle, and the diameter of the circle may be 3 mm to 8 mm.
在一些實施例中，增強區域211沿增強區域211的振動方向的投影為多邊形時，多邊形的外接圓直徑可以為2mm至10mm。在一些實施例中，增強區域211沿增強區域211的振動方向的投影為多邊形，且多邊形的外接圓直徑可以為3mm至8mm。 In some embodiments, when the projection of the enhanced region 211 along the vibration direction of the enhanced region 211 is a polygon, the circumscribed circle diameter of the polygon may be 2 mm to 10 mm. In some embodiments, the projection of the enhanced region 211 along the vibration direction of the enhanced region 211 is a polygon, and the circumscribed circle diameter of the polygon may be 3 mm to 8 mm.
在一些實施例中，對於不同形狀的增強區域211(即增強區域211沿增強區域211的振動方向具有不同的投影形狀)，可以設置增強區域211沿增強區域211的振動方向的厚度在合適範圍內，以保證振動組件200的性能。在一些實施例中，增強區域211沿增強區域211的振動方向的厚度可以為20μm至200μm。在一些實施例中，增強區域211沿增強區域211的振動方向的厚度可以為40μm至150μm。 In some embodiments, for different shapes of the enhanced region 211 (i.e., the enhanced region 211 has different projection shapes along the vibration direction of the enhanced region 211), the thickness of the enhanced region 211 along the vibration direction of the enhanced region 211 can be set within an appropriate range to ensure the performance of the vibration component 200. In some embodiments, the thickness of the enhanced region 211 along the vibration direction of the enhanced region 211 can be 20μm to 200μm. In some embodiments, the thickness of the enhanced region 211 along the vibration direction of the enhanced region 211 can be 40μm to 150μm.
在一些實施例中，增強區域211的材料可以是金屬薄膜、非金屬等中的一種或多種。在一些實施例中，金屬薄膜可以包括但不限於鋁合金、鎂 鋁合金、鈦合金、鎂鋰合金、銅、鈹、85鋼等，或其任意組合。在一些實施例中，非金屬可以包括但不限於人造和/或天然絲織產品(如絲綢、蠶絲等)、人造纖維、絲膜、布膜、尼龍膜、純碳纖維、複合碳纖維等，或其任意組合。 In some embodiments, the material of the reinforcement region 211 may be one or more of metal film, non-metal, etc. In some embodiments, the metal film may include but is not limited to aluminum alloy, magnesium aluminum alloy, titanium alloy, magnesium lithium alloy, copper, celadon, 85 steel, etc., or any combination thereof. In some embodiments, the non-metal may include but is not limited to artificial and/or natural silk products (such as silk, silk, etc.), artificial fibers, silk films, cloth films, nylon films, pure carbon fibers, composite carbon fibers, etc., or any combination thereof.
在一些實施例中，第一預處理區域212可以包括第一折環2121，第一折環2121可以具有第一彎折方向。參見圖2至圖4，第一彎折方向可以是在平行於增強區域211的振動方向的投影面上，垂直於連接第一折環2121兩端的線段S，且朝向突出於該平面的折彎部分的方向。 In some embodiments, the first pre-processing area 212 may include a first folding ring 2121, and the first folding ring 2121 may have a first bending direction. Referring to Figures 2 to 4, the first bending direction may be on a projection plane parallel to the vibration direction of the enhancement area 211, perpendicular to the line segment S connecting the two ends of the first folding ring 2121, and toward the direction of the bending portion protruding from the plane.
在一些實施例中，參見圖2，第一折環2121的一端可以與增強區域211連接，第一折環2121的另一端凸出於增強區域211垂直於振動方向的表面之外。在一些實施例中，第一彎折方向與增強區域211的振動方向可以成第一夾角。第一彎折方向與增強區域211的振動方向成第一夾角時，第一折環2121在第一彎折方向(或垂直於第一彎折方向)上可以產生形變，第一彎折方向(或垂直於第一彎折方向)上產生的形變在增強區域211的振動方向上具有一定的形變分量，該形變分量可以使第一預處理區域212為增強區域211提供沿增強區域211的振動方向的第一位移量。 In some embodiments, referring to FIG. 2 , one end of the first fold 2121 may be connected to the enhanced region 211, and the other end of the first fold 2121 may protrude from the surface of the enhanced region 211 perpendicular to the vibration direction. In some embodiments, the first bending direction and the vibration direction of the enhanced region 211 may form a first angle. When the first bending direction and the vibration direction of the enhanced region 211 form a first angle, the first fold 2121 may be deformed in the first bending direction (or perpendicular to the first bending direction), and the deformation generated in the first bending direction (or perpendicular to the first bending direction) has a certain deformation component in the vibration direction of the enhanced region 211, and the deformation component may enable the first pre-processing region 212 to provide the enhanced region 211 with a first displacement along the vibration direction of the enhanced region 211.
在一些實施例中，第一折環2121可以是弧形折環(如圓弧、橢圓弧等)。在一些實施例中，第一折環2121也可以是曲線型折環(如抛物線等)。在一些實施例中，第一折環2121還可以是折線型折環(如尖齒形折線、方齒形折線等)。 In some embodiments, the first fold ring 2121 may be an arc-shaped fold ring (such as a circular arc, an elliptical arc, etc.). In some embodiments, the first fold ring 2121 may also be a curved fold ring (such as a parabola, etc.). In some embodiments, the first fold ring 2121 may also be a fold line fold ring (such as a sharp tooth fold line, a square tooth fold line, etc.).
通過設計第一折環2121，可以使得彈性元件210沿增強區域211的振動方向具有較大的可變形量，從而提高第一預處理區域212為增強區域211提供的沿增強區域211的振動方向的第一位移量，進而提高增強區域211在其振動方向的振動幅度或振動位移，提升振動組件200的低頻靈敏度。在一些實施例中，通過設計第一折環2121，還可以使得彈性元件210振動時，第一折環2121的 整個折彎部分都能獲得較為均勻的變形，極大程度降低應力集中問題，從而使得振動組件200的可靠性提高。 By designing the first fold 2121, the elastic element 210 can have a larger deformable amount along the vibration direction of the enhanced area 211, thereby increasing the first displacement amount provided by the first pre-processing area 212 for the enhanced area 211 along the vibration direction of the enhanced area 211, thereby increasing the vibration amplitude or vibration displacement of the enhanced area 211 in its vibration direction, and improving the low-frequency sensitivity of the vibration component 200. In some embodiments, by designing the first fold 2121, when the elastic element 210 vibrates, the entire bending part of the first fold 2121 can obtain a relatively uniform deformation, greatly reducing the stress concentration problem, thereby improving the reliability of the vibration component 200.
在一些實施例中，第一彎折方向與增強區域211的振動方向所成第一夾角的角度可以位於0°至360°之間。在一些實施例中，第一彎折方向與增強區域211的振動方向所成第一夾角的角度可以位於0°至180°之間。在一些實施例中，第一彎折方向與增強區域211的振動方向所成第一夾角的角度可以位於60°至120°之間。 In some embodiments, the first angle formed by the first bending direction and the vibration direction of the enhanced region 211 may be between 0° and 360°. In some embodiments, the first angle formed by the first bending direction and the vibration direction of the enhanced region 211 may be between 0° and 180°. In some embodiments, the first angle formed by the first bending direction and the vibration direction of the enhanced region 211 may be between 60° and 120°.
在一些實施例中，參見圖3，第一折環2121可以相對於增強區域211沿垂直於增強區域211的振動方向環繞設置在增強區域211的周側。在一些實施例中，第一彎折方向與增強區域211的振動方向可以平行。第一彎折方向與增強區域211的振動方向平行時，第一折環2121在第一彎折方向上可以產生形變，即第一折環2121在增強區域211的振動方向上可以產生形變，從而使第一預處理區域212為增強區域211提供沿增強區域211的振動方向的第一位移量。第一彎折方向與增強區域211的振動方向平行時，第一位移量可以為第一預處理區域212變形後的長度(在平行於增強區域211的振動方向的投影平面上連接其兩端的長度)在振動方向上的分量。根據畢氏定理可知，該分量大於第一預處理區域212變形後長度的變化量(即變形量)，即通過將第一彎折方向與增強區域211的振動方向平行設置，可以使第一預處理區域212提供的第一位移量大於其自身的變形量，提高增強區域211的振動位移或振動幅度。 In some embodiments, referring to FIG. 3 , the first fold 2121 may be disposed around the reinforcing region 211 along a direction perpendicular to the vibration direction of the reinforcing region 211 relative to the reinforcing region 211. In some embodiments, the first bending direction may be parallel to the vibration direction of the reinforcing region 211. When the first bending direction is parallel to the vibration direction of the reinforcing region 211, the first fold 2121 may be deformed in the first bending direction, that is, the first fold 2121 may be deformed in the vibration direction of the reinforcing region 211, so that the first pre-processing region 212 provides the reinforcing region 211 with a first displacement along the vibration direction of the reinforcing region 211. When the first bending direction is parallel to the vibration direction of the enhanced region 211, the first displacement can be the component of the length of the first pre-processed region 212 after deformation (the length connecting its two ends on the projection plane parallel to the vibration direction of the enhanced region 211) in the vibration direction. According to the Pisces theorem, this component is greater than the change in the length of the first pre-processed region 212 after deformation (i.e., the deformation amount), that is, by setting the first bending direction parallel to the vibration direction of the enhanced region 211, the first displacement provided by the first pre-processed region 212 can be greater than its own deformation amount, thereby increasing the vibration displacement or vibration amplitude of the enhanced region 211.
為保證振動組件200所需諧振頻率，在振動組件200總尺寸固定的情況下，增強區域211沿其振動方向的投影尺寸越大越好。在振動組件200總尺寸固定的情況下，當增強區域211沿其振動方向的投影尺寸越大時，第一折環2121在增強區域211周圍的可佈置空間減小，進一步的，第一折環2121的尺寸減小，導致彈性元件210的剛度增加，器件諧振頻率增加。在一些實施例中，參見 圖4，第一折環2121可以設置於增強區域211平行於其振動方向的側面。在一些實施例中，第一彎折方向與增強區域211的振動方向可以垂直。在一些實施例中，第一彎折方向與增強區域211的振動方向可以垂直且背離增強區域211所在方向。第一彎折方向與增強區域211的振動方向垂直時，第一折環2121在垂直於第一彎折方向上可以產生形變，即第一折環2121在增強區域211的振動方向上可以產生形變，從而提高第一預處理區域212為增強區域211提供沿增強區域211的振動方向的第一位移量。第一彎折方向與增強區域211的振動方向垂直時，第一位移量可以為第一預處理區域212變形後長度的變化量(即變形量)。 To ensure the required resonant frequency of the vibration assembly 200, when the total size of the vibration assembly 200 is fixed, the larger the projection size of the enhanced area 211 along its vibration direction, the better. When the total size of the vibration assembly 200 is fixed, when the projection size of the enhanced area 211 along its vibration direction is larger, the space that can be arranged around the enhanced area 211 of the first fold 2121 is reduced. Further, the size of the first fold 2121 is reduced, resulting in an increase in the stiffness of the elastic element 210 and an increase in the resonant frequency of the device. In some embodiments, see Figure 4, the first fold 2121 can be arranged on the side of the enhanced area 211 parallel to its vibration direction. In some embodiments, the first bending direction may be perpendicular to the vibration direction of the enhanced region 211. In some embodiments, the first bending direction may be perpendicular to the vibration direction of the enhanced region 211 and away from the direction of the enhanced region 211. When the first bending direction is perpendicular to the vibration direction of the enhanced region 211, the first fold 2121 may be deformed perpendicular to the first bending direction, that is, the first fold 2121 may be deformed in the vibration direction of the enhanced region 211, thereby increasing the first pre-processed region 212 to provide the enhanced region 211 with a first displacement along the vibration direction of the enhanced region 211. When the first bending direction is perpendicular to the vibration direction of the enhanced region 211, the first displacement may be the change in length of the first pre-processed region 212 after deformation (i.e., the deformation amount).
相比於其他非垂直的設置方式，通過將第一彎折方向設置為垂直於增強區域211的振動方向，可以使得第一折環2121具有更大的設計尺寸，從而使第一折環2121沿增強區域211的振動方向的變形能力大幅提升(即具有更大的變形量)，從而可以極大的降低彈性元件210沿增強區域211的振動方向的剛度，同時減小第一折環2121沿增強區域211的振動方向的投影尺寸。 Compared with other non-vertical settings, by setting the first bending direction to be perpendicular to the vibration direction of the enhanced region 211, the first fold 2121 can have a larger design size, thereby greatly improving the deformation ability of the first fold 2121 along the vibration direction of the enhanced region 211 (i.e., having a larger deformation amount), thereby greatly reducing the rigidity of the elastic element 210 along the vibration direction of the enhanced region 211, and reducing the projection size of the first fold 2121 along the vibration direction of the enhanced region 211.
在一些實施例中，為了提高第一折環2121在增強區域211振動過程中的變形量，參見圖2至圖4，第一折環2121沿第一彎折方向的高度尺寸和沿垂直於第一彎折方向的長度尺寸可以進行合理的設置，以滿足增強區域211沿其振動方向的位移量的需求。在一些實施例中，第一折環2121沿第一彎折方向的高度尺寸可以用平行於增強區域211的振動方向的投影平面上，第一折環2121的折彎部分在第一彎折方向上相距線段S的距離尺寸的最大值表示。第一折環2121沿垂直於第一彎折方向的長度尺寸可以用第一折環2121在平行於增強區域211的振動方向的投影平面上連接其兩端的直線的距離(即線段S的長度)尺寸表示。 In some embodiments, in order to increase the deformation of the first fold 2121 during the vibration of the reinforcement area 211, referring to FIGS. 2 to 4, the height dimension of the first fold 2121 along the first bending direction and the length dimension perpendicular to the first bending direction can be reasonably set to meet the displacement requirement of the reinforcement area 211 along its vibration direction. In some embodiments, the height dimension of the first fold 2121 along the first bending direction can be represented by the maximum value of the distance dimension of the bending part of the first fold 2121 from the line segment S in the first bending direction on a projection plane parallel to the vibration direction of the reinforcement area 211. The length of the first fold ring 2121 along the direction perpendicular to the first bending direction can be represented by the distance of the straight line connecting the two ends of the first fold ring 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 (i.e. the length of the line segment S).
在一些實施例中，第一折環2121在平行於增強區域211的振動方向的投影平面上投影形狀的高度尺寸可以為50μm至250μm。在一些實施例中，第一折環2121在平行於增強區域211的振動方向的投影平面上投影形狀的高度 尺寸可以為80μm至200μm。在一些實施例中，將第一折環2121在平行於增強區域211振動方向的投影平面上的投影形狀中，沿其投影形狀的徑向或其投影形狀的外接圓的徑向方向的尺寸定義為第一折環2121的長度尺寸。在一些實施例中，第一折環2121在平行於增強區域211振動方向的投影平面上投影形狀的長度尺寸可以為400μm至800μm。在一些實施例中，第一折環2121在平行於增強區域211振動方向的投影平面上投影形狀的長度尺寸可以為500μm至700μm。在一些實施例中，第一折環2121在平行於增強區域211的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：16至5：8之間。在一些實施例中，第一折環2121在平行於增強區域211的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：8至1：2之間。在一些實施例中，第一折環2121在平行於增強區域211的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：4至3：4之間。 In some embodiments, the height dimension of the projection shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be 50 μm to 250 μm. In some embodiments, the height dimension of the projection shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be 80 μm to 200 μm. In some embodiments, the dimension of the projection shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 along the radial direction of the projection shape or the radial direction of the circumscribed circle of the projection shape is defined as the length dimension of the first fold 2121. In some embodiments, the length dimension of the projection shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be 400 μm to 800 μm. In some embodiments, the length dimension of the projected shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be 500μm to 700μm. In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be between 1:16 and 5:8. In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be between 1:8 and 1:2. In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the first fold 2121 on the projection plane parallel to the vibration direction of the enhanced region 211 may be between 1:4 and 3:4.
在一些實施例中，第一預處理區域212(第一折環2121)為增強區域211提供的沿增強區域211的振動方向的第一位移量可以為1μm至50μm。在一些實施例中，第一預處理區域212(第一折環2121)為增強區域211提供的沿增強區域211的振動方向的第一位移量可以為4μm至30μm。 In some embodiments, the first displacement amount provided by the first pre-processed area 212 (first fold 2121) for the enhanced area 211 along the vibration direction of the enhanced area 211 may be 1 μm to 50 μm. In some embodiments, the first displacement amount provided by the first pre-processed area 212 (first fold 2121) for the enhanced area 211 along the vibration direction of the enhanced area 211 may be 4 μm to 30 μm.
在一些實施例中，參見圖2至圖6，第一折環2121在平行於增強區域211的振動方向的截面上的截面形狀可以包括但不限於圓弧狀、橢圓弧狀、折線狀、尖齒狀、方齒狀中的一種或多種。例如，如圖2至圖4所示，第一折環2121在平行於增強區域211的振動方向的截面上的截面形狀為圓弧狀。又例如，如圖5所示，第一折環2121在平行於增強區域211的振動方向的截面上的截面形狀為方齒狀。再例如，如圖6所示，第一折環2121在平行於增強區域211的振動方向的截面上的截面形狀為尖齒狀。 In some embodiments, referring to FIGS. 2 to 6, the cross-sectional shape of the first folded ring 2121 on the cross-sectional shape parallel to the vibration direction of the enhanced region 211 may include but is not limited to one or more of a circular arc, an elliptical arc, a broken line, a sharp tooth, and a square tooth. For example, as shown in FIGS. 2 to 4, the cross-sectional shape of the first folded ring 2121 on the cross-sectional shape parallel to the vibration direction of the enhanced region 211 is a circular arc. For another example, as shown in FIG. 5, the cross-sectional shape of the first folded ring 2121 on the cross-sectional shape parallel to the vibration direction of the enhanced region 211 is a square tooth. For another example, as shown in FIG. 6, the cross-sectional shape of the first folded ring 2121 on the cross-sectional shape parallel to the vibration direction of the enhanced region 211 is a sharp tooth.
在一些實施例中，在增強區域211的振動方向上，具有不同截面 形狀的第一折環2121可以具有不同的形變能力，使得第一預處理區域212為增強區域211提供沿增強區域211的振動方向的第一位移量不同。在一些實施例中，可以根據第一預處理區域212為增強區域211提供沿增強區域211的振動方向的第一位移量的需求，對第一折環2121的截面形狀進行相應設置，本說明書實施例對此不做特別限定。 In some embodiments, in the vibration direction of the enhanced region 211, the first fold ring 2121 with different cross-sectional shapes may have different deformation capabilities, so that the first pre-processed region 212 provides different first displacements for the enhanced region 211 along the vibration direction of the enhanced region 211. In some embodiments, the cross-sectional shape of the first fold ring 2121 may be set accordingly according to the requirement that the first pre-processed region 212 provides the enhanced region 211 with the first displacement along the vibration direction of the enhanced region 211, and the embodiments of this specification do not specifically limit this.
在一些實施例中，參見圖2至圖6，支撐元件220可以位於固定區域213沿增強區域211的振動方向的任一表面，並與固定區域213連接(如黏接)。在一些實施例中，振動組件200設置於揚聲器中時，支撐元件220可以與揚聲器的其他結構(如殼體)連接以支撐彈性元件210。 In some embodiments, referring to FIGS. 2 to 6 , the support element 220 may be located on any surface of the fixed area 213 along the vibration direction of the enhanced area 211 and connected (e.g., bonded) to the fixed area 213. In some embodiments, when the vibration assembly 200 is disposed in a loudspeaker, the support element 220 may be connected to other structures of the loudspeaker (e.g., a housing) to support the elastic element 210.
在一些實施例中，支撐元件220的材料可以是半導體材料、有機高分子材料、膠類材料等中的一種或多種。半導體材料可以包括但不限於矽、二氧化矽、氮化矽、碳化矽等中的一種或多種。有機高分子材料可以包括但不限於聚醯亞胺(PI)、派瑞林、聚二甲基矽氧烷(PDMS)、水凝膠、塑膠等中的一種或多種。膠類材料可以包括但不限於凝膠類、有機矽膠、丙烯酸類、聚氨酯類、橡膠類、環氧類、熱熔類、光固化類等中的一種或多種。在一些實施例中，為了增強支撐元件220與彈性元件210(固定區域213)之間的連接力，提高支撐元件220與彈性元件210之間的可靠性，支撐元件220的材料可以為有機矽黏接類膠水、有機矽密封類膠水等。在一些實施例中，支撐元件220的材料也可以是剛性材料。在一些實施例中，剛性材料可以包括但不限於金屬材料、合金材料等。 In some embodiments, the material of the support element 220 may be one or more of a semiconductor material, an organic polymer material, a rubber material, etc. The semiconductor material may include but is not limited to one or more of silicon, silicon dioxide, silicon nitride, silicon carbide, etc. The organic polymer material may include but is not limited to one or more of polyimide (PI), parylene, polydimethylsiloxane (PDMS), hydrogel, plastic, etc. The rubber material may include but is not limited to one or more of gel, organic silicone, acrylic, polyurethane, rubber, epoxy, hot melt, light curing, etc. In some embodiments, in order to enhance the connection force between the support element 220 and the elastic element 210 (fixed area 213) and improve the reliability between the support element 220 and the elastic element 210, the material of the support element 220 may be organic silicone adhesive glue, organic silicone sealing glue, etc. In some embodiments, the material of the support element 220 may also be a rigid material. In some embodiments, the rigid material may include but is not limited to metal materials, alloy materials, etc.
在一些實施例中，支撐元件220也可以沿增強區域221的振動方向發生一定程度的形變，從而為增強區域221提供沿增強區域221的振動方向的位移量。在一些實施例中，支撐元件220可以包括形變部，形變部在沿增強區域211的振動方向上可以具有一定的形變能力，從而為增強區域221提供沿增強區域 221的振動方向的位移量，進一步提高增強區域211沿其振動方向的振動幅度或振動位移，提升振動組件200的低頻靈敏度。關於支撐元件220的具體內容可以參見圖19至圖28，及其相關描述。 In some embodiments, the support element 220 may also deform to a certain extent along the vibration direction of the enhanced region 221, thereby providing the enhanced region 221 with a displacement along the vibration direction of the enhanced region 221. In some embodiments, the support element 220 may include a deformation portion, which may have a certain deformation ability along the vibration direction of the enhanced region 211, thereby providing the enhanced region 221 with a displacement along the vibration direction of the enhanced region 221, further improving the vibration amplitude or vibration displacement of the enhanced region 211 along its vibration direction, and improving the low-frequency sensitivity of the vibration assembly 200. For the specific content of the support element 220, please refer to Figures 19 to 28 and their related descriptions.
圖7至圖18是根據本說明書的一些實施例所示的振動組件示例性結構圖。 Figures 7 to 18 are exemplary structural diagrams of vibration components according to some embodiments of this specification.
在一些實施例中，振動組件700的一個或多個元件(例如，增強區域711、第一預處理區域712、固定區域714、支撐元件720等)與圖2至圖6所示的振動組件200的一個或多個元件(例如，增強區域211、第一預處理區域212、固定區域213、支撐元件220等)可以相同或相似，即振動組件700可以包括增強區域711、第一預處理區域712、固定區域714和支撐元件720。與振動組件200的不同之處在於，振動組件700的彈性元件710還可以包括第二預處理區域713。第二預處理區域713可以為增強區域711提供沿增強區域711的振動方向的第二位移量。第二位移量可以是第二預處理區域713為增強區域711在其振動方向上的振動過程中所貢獻的位移大小。 In some embodiments, one or more elements of the vibration assembly 700 (e.g., the enhancement region 711, the first pre-processing region 712, the fixed region 714, the support element 720, etc.) may be the same or similar to one or more elements of the vibration assembly 200 shown in FIGS. 2 to 6 (e.g., the enhancement region 211, the first pre-processing region 212, the fixed region 213, the support element 220, etc.), that is, the vibration assembly 700 may include the enhancement region 711, the first pre-processing region 712, the fixed region 714 and the support element 720. The difference from the vibration assembly 200 is that the elastic element 710 of the vibration assembly 700 may further include a second pre-processing region 713. The second pre-processing region 713 may provide the enhancement region 711 with a second displacement along the vibration direction of the enhancement region 711. The second displacement amount can be the displacement size contributed by the second pre-processing area 713 to the enhanced area 711 during the vibration process in its vibration direction.
在一些實施例中，通過設置彈性元件710的第二預處理區域713，可以為增強區域711提供的沿增強區域711振動方向的第二位移量，從而進一步提高增強區域711在其振動方向上的振動位移或振動幅度(包括第一位移量和第二位移量)。增強區域711在其振動方向上的振動位移或振動幅度提高，可以使得彈性元件710振動時能推動更多的空氣振動，進而提高振動組件700的低頻靈敏度。在一些實施例中，當振動組件700振動幅度較大時，第一預處理區域712和第二預處理區域713可以通過變形將振動衝擊能量以變形能形式分別存儲在第一預處理區域712和第二預處理區域713內部，第一預處理區域712和第二預處理區域713進行多次阻尼衰減運動，進而將較大的振動衝擊能量通過阻尼運動進行消散，避免振動組件700(尤其是彈性元件710)在振動時損壞，提高振動組 件700的可靠性。 In some embodiments, by providing the second pre-processing region 713 of the elastic element 710, a second displacement amount along the vibration direction of the enhanced region 711 can be provided for the enhanced region 711, thereby further improving the vibration displacement or vibration amplitude (including the first displacement amount and the second displacement amount) of the enhanced region 711 in its vibration direction. The increased vibration displacement or vibration amplitude of the enhanced region 711 in its vibration direction can enable the elastic element 710 to push more air vibrations when vibrating, thereby improving the low-frequency sensitivity of the vibration assembly 700. In some embodiments, when the vibration amplitude of the vibration component 700 is large, the first pre-processing area 712 and the second pre-processing area 713 can store the vibration impact energy in the first pre-processing area 712 and the second pre-processing area 713 in the form of deformation energy by deformation, and the first pre-processing area 712 and the second pre-processing area 713 perform multiple damping attenuation movements, thereby dissipating the large vibration impact energy through damping movements, avoiding damage to the vibration component 700 (especially the elastic element 710) during vibration, and improving the reliability of the vibration component 700.
在一些實施例中，第一預處理區域712為增強區域711提供的沿增強區域711振動方向的第一位移量與第二預處理區域713為增強區域711提供的沿增強區域711振動方向的第二位移量可以相同或不同。在一些實施例中，第一位移量與第二位移量的比值可以為1：50至50：1。在一些實施例中，第一位移量與第二位移量的比值可以為1：10至10：1。在一些實施例中，第一位移量與第二位移量的比值可以為1：2至5：1。在一些實施例中，第二預處理區域713(或第一預處理區域712)為增強區域711提供的沿增強區域711振動方向的第二位移量(或第一位移量)可以為1μm至50μm。在一些實施例中，第二預處理區域713(或第一預處理區域712)為增強區域711提供的沿增強區域711振動方向的第二位移量(或第一位移量)可以為4μm至30μm。 In some embodiments, the first displacement amount along the vibration direction of the enhancement region 711 provided by the first pre-processed region 712 for the enhancement region 711 and the second displacement amount along the vibration direction of the enhancement region 711 provided by the second pre-processed region 713 for the enhancement region 711 may be the same or different. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:50 to 50:1. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:10 to 10:1. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:2 to 5:1. In some embodiments, the second displacement amount (or the first displacement amount) along the vibration direction of the enhancement region 711 provided by the second pre-processed region 713 (or the first pre-processed region 712) for the enhancement region 711 may be 1μm to 50μm. In some embodiments, the second displacement (or first displacement) provided by the second pre-processed area 713 (or the first pre-processed area 712) for the enhanced area 711 along the vibration direction of the enhanced area 711 may be 4μm to 30μm.
在一些實施例中，第二預處理區域713可以環繞設置於第一預處理區域712的週邊，固定區域714環繞設置於第二預處理區域713的週邊。在一些實施例中，第二預處理區域713的內周側(靠近增強區域711的周側)與第一預處理區域712的周側環繞連接，第二預處理區域713的外周側(遠離增強區域711的周側)與固定區域714的周側環繞連接。在一些實施例中，彈性元件710的增強區域711、第一預處理區域712、第二預處理區域713、固定區域714沿增強區域711的振動方向的投影由內至外依次排列。在一些實施例中，彈性元件710和增強區域711沿增強區域711的振動方向的投影可以為圓形、矩形、五邊形、六邊形等規則和/或不規則多邊形。第二預處理區域713沿增強區域711的振動方向的投影可以為與圓形、矩形、五邊形、六邊形等規則和/或不規則多邊形對應的圓環、矩形環、五邊形環、六邊形環等規則和/或不規則多邊形環。 In some embodiments, the second pre-processing area 713 may be disposed around the first pre-processing area 712, and the fixed area 714 may be disposed around the second pre-processing area 713. In some embodiments, the inner periphery of the second pre-processing area 713 (the periphery close to the enhancement area 711) is connected to the periphery of the first pre-processing area 712, and the outer periphery of the second pre-processing area 713 (the periphery far from the enhancement area 711) is connected to the periphery of the fixed area 714. In some embodiments, the projections of the enhanced area 711, the first pre-processed area 712, the second pre-processed area 713, and the fixed area 714 of the elastic element 710 along the vibration direction of the enhanced area 711 are arranged in sequence from the inside to the outside. In some embodiments, the projections of the elastic element 710 and the enhanced area 711 along the vibration direction of the enhanced area 711 can be regular and/or irregular polygons such as circles, rectangles, pentagons, and hexagons. The projection of the second pre-processed area 713 along the vibration direction of the enhanced area 711 can be regular and/or irregular polygonal rings such as circular rings, rectangular rings, pentagonal rings, and hexagonal rings corresponding to regular and/or irregular polygons such as circles, rectangles, pentagons, and hexagons.
在一些實施例中，參見圖7至9，第二預處理區域713與第一預處理區域712可以直接連接，即，第二預處理區域713與第一預處理區域712之間的 間距為零。第二預處理區域713與第一預處理區域712直接連接，也可以理解為，第二預處理區域713的周側(靠近第一預處理區域712的周側)與第一預處理區域712的周側(靠近第二預處理區域713的周側)直接連接。 In some embodiments, referring to FIGS. 7 to 9 , the second preprocessing area 713 and the first preprocessing area 712 may be directly connected, that is, the spacing between the second preprocessing area 713 and the first preprocessing area 712 is zero. The second preprocessing area 713 is directly connected to the first preprocessing area 712, which can also be understood as the periphery of the second preprocessing area 713 (the periphery close to the first preprocessing area 712) and the periphery of the first preprocessing area 712 (the periphery close to the second preprocessing area 713) are directly connected.
在一些實施例中，參見圖10至11，第二預處理區域713與第一預處理區域712也可以間隔設置，即，第二預處理區域713與第一預處理區域712之間具有特定間距d。特定間距d可以是第二預處理區域713的周側(靠近第一預處理區域712的周側)與第一預處理區域712的周側(靠近第二預處理區域713的周側)之間的間距。在一些實施例中，第二預處理區域713的周側與第一預處理區域712的周側可以通過非預處理區域連接。在一些實施例中，非預處理區域在垂直於增強區域711的振動方向的平面上的投影的寬度為d。 In some embodiments, referring to FIGS. 10 to 11 , the second pre-processing region 713 and the first pre-processing region 712 may also be arranged at intervals, that is, there is a specific spacing d between the second pre-processing region 713 and the first pre-processing region 712. The specific spacing d may be the spacing between the periphery of the second pre-processing region 713 (the periphery close to the first pre-processing region 712) and the periphery of the first pre-processing region 712 (the periphery close to the second pre-processing region 713). In some embodiments, the periphery of the second pre-processing region 713 and the periphery of the first pre-processing region 712 may be connected through a non-pre-processing region. In some embodiments, the width of the projection of the non-pre-processing region on a plane perpendicular to the vibration direction of the enhancement region 711 is d.
在一些實施例中，第二預處理區域713與第一預處理區域712之間直接連接或間隔設置可以調整第二預處理區域713和第一預處理區域712的形變能力，進而調整第二預處理區域713為增強區域711提供的沿增強區域711振動方向的第二位移量，且第一預處理區域712為增強區域711提供的沿增強區域711振動方向的第一位移量。另一方面，第二預處理區域713與第一預處理區域712之間直接連接或間隔設置也可以調整彈性元件710的剛度。在一些實施例中，第二預處理區域713與第一預處理區域712之間直接連接時彈性元件710的剛度可以小於第二預處理區域713與第一預處理區域712之間間隔設置時彈性元件710的剛度。在一些實施例中，通過設置第二預處理區域713與第一預處理區域712之間的連接方式，可以調整振動組件700的諧振頻率和靈敏度。 In some embodiments, the direct connection or spacing between the second pre-processed area 713 and the first pre-processed area 712 can adjust the deformation capacity of the second pre-processed area 713 and the first pre-processed area 712, thereby adjusting the second displacement provided by the second pre-processed area 713 for the enhanced area 711 along the vibration direction of the enhanced area 711, and the first displacement provided by the first pre-processed area 712 for the enhanced area 711 along the vibration direction of the enhanced area 711. On the other hand, the direct connection or spacing between the second pre-processed area 713 and the first pre-processed area 712 can also adjust the stiffness of the elastic element 710. In some embodiments, the stiffness of the elastic element 710 when the second pre-processing area 713 and the first pre-processing area 712 are directly connected can be less than the stiffness of the elastic element 710 when the second pre-processing area 713 and the first pre-processing area 712 are spaced apart. In some embodiments, the resonant frequency and sensitivity of the vibration assembly 700 can be adjusted by setting the connection method between the second pre-processing area 713 and the first pre-processing area 712.
在一些實施例中，第二預處理區域713與第一預處理區域712之間的特定間距d的取值範圍可以為0μm至500μm。在一些實施例中，第二預處理區域713與第一預處理區域712之間的特定間距d的取值範圍可以為0μm至300μm。在一些實施例中，第二預處理區域713與第一預處理區域712之間的特定間 距d的取值範圍可以為0μm至100μm。 In some embodiments, the specific spacing d between the second pre-processed area 713 and the first pre-processed area 712 may range from 0 μm to 500 μm. In some embodiments, the specific spacing d between the second pre-processed area 713 and the first pre-processed area 712 may range from 0 μm to 300 μm. In some embodiments, the specific spacing d between the second pre-processed area 713 and the first pre-processed area 712 may range from 0 μm to 100 μm.
在一些實施例中，參見圖12至圖15，第二預處理區域713可以包括第二折環7131。第二折環7131可以具有第二彎折方向。第二彎折方向可以是垂直於連接第二折環7131兩端點的平面，且朝向突出於該平面的折彎部分的方向。 In some embodiments, referring to FIGS. 12 to 15 , the second pre-processing area 713 may include a second folding ring 7131. The second folding ring 7131 may have a second bending direction. The second bending direction may be perpendicular to the plane connecting the two end points of the second folding ring 7131 and toward the direction of the folded portion protruding from the plane.
在一些實施例中，第二折環7131在平行於增強區域711的振動方向的截面上的截面形狀可以包括但不限於圓弧狀(例如，圖8)、橢圓弧狀、折線狀、尖齒狀(例如，圖9)、方齒狀(例如，圖10)中的一種或多種。在一些實施例中，在增強區域711的振動方向上，具有不同截面形狀的第二折環7131可以具有不同的形變能力，使得第二預處理區域713為增強區域711提供沿增強區域711的振動方向的第二位移量不同。在一些實施例中，可以根據第二預處理區域713為增強區域711提供沿增強區域711的振動方向的第二位移量的需求，對第二折環7131的截面形狀進行相應設置，本說明書實施例對此不做特別限定。 In some embodiments, the cross-sectional shape of the second fold 7131 in the cross section parallel to the vibration direction of the enhanced region 711 may include, but is not limited to, one or more of a circular arc shape (e.g., FIG. 8 ), an elliptical arc shape, a broken line shape, a sharp tooth shape (e.g., FIG. 9 ), and a square tooth shape (e.g., FIG. 10 ). In some embodiments, in the vibration direction of the enhanced region 711, the second fold 7131 with different cross-sectional shapes may have different deformation capabilities, so that the second pre-processing region 713 provides the enhanced region 711 with different second displacement amounts along the vibration direction of the enhanced region 711. In some embodiments, the cross-sectional shape of the second fold 7131 can be set accordingly according to the requirement that the second pre-processing area 713 provides the enhanced area 711 with a second displacement along the vibration direction of the enhanced area 711, and the embodiments of this specification do not specifically limit this.
在一些實施例中，參見圖12，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以相同。在一些實施例中，參見圖13至圖15，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以不同。在一些實施例中，第一折環和第二折環為平滑曲線(曲率不等於0，且曲線的一階導數連續)，當第一折環7121的第一彎折方向與第二折環7131的第二彎折方向相同時，第一折環7121上一點對應的曲率中心和第二折環7131上一點對應的曲率中心可以位於彈性元件在增強區域711的振動方向上的同一側。在一些實施例中，第一折環和第二折環為平滑曲線(曲率不等於0，且曲線的一階導數連續)，當第一折環7121的第一彎折方向與第二折環7131的第二彎折方向不相同時，第一折環7121上一點對應的曲率中心和第二折環7131上一點對應的曲率中心可以分別位於彈性元件在增強區域711的振動方向上的兩側。 In some embodiments, referring to FIG. 12 , the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be the same. In some embodiments, referring to FIG. 13 to FIG. 15 , the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be different. In some embodiments, the first fold and the second fold are smooth curves (the curvature is not equal to 0, and the first-order derivative of the curve is continuous). When the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 are the same, the center of curvature corresponding to a point on the first fold 7121 and the center of curvature corresponding to a point on the second fold 7131 may be located on the same side of the elastic element in the vibration direction of the reinforcement region 711. In some embodiments, the first fold ring and the second fold ring are smooth curves (the curvature is not equal to 0, and the first-order derivative of the curve is continuous). When the first bending direction of the first fold ring 7121 is different from the second bending direction of the second fold ring 7131, the curvature center corresponding to a point on the first fold ring 7121 and the curvature center corresponding to a point on the second fold ring 7131 can be located on both sides of the elastic element in the vibration direction of the enhanced area 711, respectively.
在一些實施例中，參見圖13，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以相反。第一折環7121的第一彎折方向與第二折環7131的第二彎折方向相反可以是第一折環7121的折彎部分突出的方向與第二折環7131的折彎部分突出的方向在同一平面內朝向相反。這種設置方式下，增強區域711沿增強區域711的振動方向的振動位移或振動幅度由第一位移量H1和第二位移量H2疊加而成。 In some embodiments, referring to FIG. 13 , the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be opposite. The first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be opposite to each other in that the protruding direction of the bending portion of the first fold 7121 and the protruding direction of the bending portion of the second fold 7131 are opposite in the same plane. In this setting, the vibration displacement or vibration amplitude of the enhanced region 711 along the vibration direction of the enhanced region 711 is formed by the superposition of the first displacement amount H1 and the second displacement amount H2.
在一些實施例中，參見圖14A至圖14C，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以垂直。在一些實施例中，參見圖14A，第一折環7121的第一彎折方向平行於增強區域711的振動方向，第二折環7131的一端與第一折環連接，第二折環7131的另一端沿第一彎折方向遠離增強區域711所在平面。在一些實施例中，第二彎折方向垂直於增強區域711的振動方向。在一些實施例中，參見圖14A，第二折環7131的第二彎折方向背離彈性元件710的中部。在一些實施例中，第二彎折方向的第二彎折方向朝向彈性元件710的中部。這種設置方式下，增強區域711沿增強區域711的振動方向的振動位移或振動幅度由第一位移量H1和第二位移量H2疊加而成。在一些實施例中，參見圖14B和圖14C，第一折環7121的第一彎折方向平行於增強區域711的振動方向，第二折環7131的一端與第一折環7121連接，第二折環7131的另一端沿與第一彎折方向相反的方向遠離增強區域711所在平面。在一些實施例中，第二彎折方向垂直於增強區域711的振動方向。在一些實施例中，參見圖14B，第二折環7131的第二彎折方向朝向彈性元件710的中部。在一些實施例中，參見圖14C，第二折環7131的第二彎折方向背離彈性元件710的中部。這種設置方式下，增強區域711沿增強區域711的振動方向的振動位移或振動幅度由第一位移量H1和第二位移量H2疊加而成。 In some embodiments, referring to FIGS. 14A to 14C , the first bending direction of the first fold 7121 may be perpendicular to the second bending direction of the second fold 7131. In some embodiments, referring to FIG. 14A , the first bending direction of the first fold 7121 is parallel to the vibration direction of the reinforcement region 711, one end of the second fold 7131 is connected to the first fold, and the other end of the second fold 7131 is away from the plane where the reinforcement region 711 is located along the first bending direction. In some embodiments, the second bending direction is perpendicular to the vibration direction of the reinforcement region 711. In some embodiments, referring to FIG. 14A , the second bending direction of the second fold 7131 is away from the middle of the elastic element 710. In some embodiments, the second bending direction of the second bending direction is toward the middle of the elastic element 710. In this arrangement, the vibration displacement or vibration amplitude of the enhanced region 711 along the vibration direction of the enhanced region 711 is formed by the superposition of the first displacement H1 and the second displacement H2. In some embodiments, referring to FIG. 14B and FIG. 14C , the first bending direction of the first fold 7121 is parallel to the vibration direction of the enhanced region 711, one end of the second fold 7131 is connected to the first fold 7121, and the other end of the second fold 7131 is away from the plane where the enhanced region 711 is located in a direction opposite to the first bending direction. In some embodiments, the second bending direction is perpendicular to the vibration direction of the enhanced region 711. In some embodiments, see FIG. 14B , the second bending direction of the second fold 7131 is toward the middle of the elastic element 710. In some embodiments, see FIG. 14C , the second bending direction of the second fold 7131 is away from the middle of the elastic element 710. In this setting, the vibration displacement or vibration amplitude of the enhanced region 711 along the vibration direction of the enhanced region 711 is formed by the superposition of the first displacement H1 and the second displacement H2.
通過將第一折環7121的第一彎折方向與第二折環7131的第二彎 折方向設置為相互垂直，可以使第二折環7131具有更大的設計尺寸，從而使得第二折環7131在增強區域711的振動方向上具有更大的形變量，進而提高第二預處理區域1122為增強區域711提供沿增強區域711的振動方向的第二位移量，進一步提高增強區域711沿其振動方向的振動位移或振動幅度，提升振動組件700的低頻靈敏度。 By setting the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 to be perpendicular to each other, the second fold 7131 can have a larger design size, so that the second fold 7131 has a larger deformation amount in the vibration direction of the enhanced area 711, thereby increasing the second displacement amount provided by the second pre-processing area 1122 for the enhanced area 711 along the vibration direction of the enhanced area 711, further increasing the vibration displacement or vibration amplitude of the enhanced area 711 along its vibration direction, and improving the low-frequency sensitivity of the vibration assembly 700.
在一些實施例中，如圖15所示，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以成第二夾角。這種設置方式下，增強區域711沿增強區域711的振動方向的振動位移或振動幅度由第一位移量H1和第二位移量H2疊加而成。在一些實施例中，通過設置第一折環7121的第一彎折方向和第二折環7131的第二彎折方向，可以調整第一位移量H1和第二位移量H2的大小，進而調整增強區域711沿增強區域711的振動方向的振動位移或振動幅度。 In some embodiments, as shown in FIG. 15 , the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may form a second angle. In this setting, the vibration displacement or vibration amplitude of the enhanced region 711 along the vibration direction of the enhanced region 711 is formed by the superposition of the first displacement H1 and the second displacement H2. In some embodiments, by setting the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131, the magnitude of the first displacement H1 and the second displacement H2 can be adjusted, thereby adjusting the vibration displacement or vibration amplitude of the enhanced region 711 along the vibration direction of the enhanced region 711.
在一些實施例中，第一彎折方向與第二彎折方向所成第二夾角的角度可以位於0°至360°之間。在一些實施例中，第一彎折方向與第二彎折方向所成第二夾角的角度可以位於60°至120°之間。 In some embodiments, the angle of the second angle formed by the first bending direction and the second bending direction may be between 0° and 360°. In some embodiments, the angle of the second angle formed by the first bending direction and the second bending direction may be between 60° and 120°.
在一些實施例中，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以平行。例如，如圖12至圖13所示，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向平行。第一折環7121的第一彎折方向與第二折環7131的第二彎折方向平行時，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向可以相同(例如，圖12所示)或相反(例如，圖13所示)。 In some embodiments, the first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 may be parallel. For example, as shown in FIGS. 12 to 13, the first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 are parallel. When the first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 are parallel, the first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 may be the same (for example, as shown in FIG. 12) or opposite (for example, as shown in FIG. 13).
需要說明的是，本說明書中對於第一彎折方向和第二彎折方向的設定可以在各實施例所描述的方向上允許存在一定的誤差(例如，角度偏移±10°以內)，而不是必須嚴格精確設置。 It should be noted that the setting of the first bending direction and the second bending direction in this specification may allow a certain error (for example, the angle deviation is within ±10°) in the directions described in each embodiment, but it does not have to be strictly and accurately set.
在一些實施例中，第一折環7121的第一彎折方向與第二折環7131的第二彎折方向不同，可以使得第一預處理區域712和第二預處理區域713沿增 強區域711的振動方向具有更強的形變能力，從而提高預處理區域為增強區域711提供沿增強區域711的振動方向的振動位移或振動幅度。 In some embodiments, the first bending direction of the first fold 7121 is different from the second bending direction of the second fold 7131, so that the first pre-processed area 712 and the second pre-processed area 713 have stronger deformation ability along the vibration direction of the enhanced area 711, thereby improving the vibration displacement or vibration amplitude provided by the pre-processed area to the enhanced area 711 along the vibration direction of the enhanced area 711.
在一些實施例中，第二折環7131在垂直於增強區域711振動方向的平面上的投影面積可以小於第一折環7121在垂直於該振動方向的平面上的投影面積，使得第二折環7131提高第二位移量的同時，第二折環7131與第一折環7121沿增強區域711在垂直於該振動方向的平面上的總投影面積的增加量很小。第二折環7131與第一折環7121在垂直於該振動方向的平面上的總投影面積較小，可以使得增強區域711在垂直於增強區域711的振動方向的平面上具有較大的投影面積，增強區域711振動過程中可以推動更多的空氣振動，進而提高振動組件700的低頻性能。 In some embodiments, the projection area of the second fold 7131 on the plane perpendicular to the vibration direction of the enhanced region 711 may be smaller than the projection area of the first fold 7121 on the plane perpendicular to the vibration direction, so that while the second fold 7131 increases the second displacement, the increase in the total projection area of the second fold 7131 and the first fold 7121 along the enhanced region 711 on the plane perpendicular to the vibration direction is very small. The total projection area of the second fold 7131 and the first fold 7121 on the plane perpendicular to the vibration direction is relatively small, so that the enhanced region 711 has a larger projection area on the plane perpendicular to the vibration direction of the enhanced region 711. During the vibration process of the enhanced region 711, more air vibration can be driven, thereby improving the low-frequency performance of the vibration component 700.
在一些實施例中，第二折環7131沿增強區域711的振動方向的投影面積與第一折環7121沿增強區域711的振動方向的投影面積之比可以為1：60至1：2。在一些實施例中，第二折環7131沿增強區域711的振動方向的投影面積與第一折環7121沿增強區域711的振動方向的投影面積之比可以為1：50至2：5。在一些實施例中，第二折環7131沿增強區域711的振動方向的投影面積與第一折環7121沿增強區域711的振動方向的投影面積之比可以為1：20至1：5。 In some embodiments, the ratio of the projection area of the second fold 7131 along the vibration direction of the enhanced region 711 to the projection area of the first fold 7121 along the vibration direction of the enhanced region 711 may be 1:60 to 1:2. In some embodiments, the ratio of the projection area of the second fold 7131 along the vibration direction of the enhanced region 711 to the projection area of the first fold 7121 along the vibration direction of the enhanced region 711 may be 1:50 to 2:5. In some embodiments, the ratio of the projection area of the second fold 7131 along the vibration direction of the enhanced region 711 to the projection area of the first fold 7121 along the vibration direction of the enhanced region 711 may be 1:20 to 1:5.
在一些實施例中，可以設置第二折環7131沿第二彎折方向的尺寸(例如，長度尺寸、高度尺寸)，以滿足第二預處理區域713為增強區域711提供的沿增強區域711的振動方向的第二位移量。 In some embodiments, the size of the second fold ring 7131 along the second bending direction (e.g., length size, height size) can be set to meet the second displacement amount along the vibration direction of the enhancement region 711 provided by the second pre-processing region 713 for the enhancement region 711.
在一些實施例中，第二折環7131在平行於增強區域711的振動方向的投影平面上投影形狀的高度尺寸可以為50μm至250μm。在一些實施例中，第二折環7131在平行於增強區域711的振動方向的投影平面上投影形狀的高度尺寸可以為80μm至200μm。 In some embodiments, the height dimension of the projected shape of the second fold 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 may be 50 μm to 250 μm. In some embodiments, the height dimension of the projected shape of the second fold 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 may be 80 μm to 200 μm.
在一些實施例中，將第二折環7131在平行於增強區域711振動方 向的投影平面上的投影形狀中，沿其投影形狀的徑向或其投影形狀的外接圓的徑向方向的尺寸定義為第二折環7131的長度尺寸。在一些實施例中，第二折環7131在平行於增強區域711振動方向的投影平面上投影形狀的長度尺寸可以為400μm至800μm。在一些實施例中，第二折環7131在平行於增強區域711振動方向的投影平面上投影形狀的長度尺寸可以為500μm至700μm。 In some embodiments, the projected shape of the second folded ring 7131 on the projection plane parallel to the vibration direction of the enhanced region 711, the dimension along the radial direction of its projected shape or the radial direction of the circumscribed circle of its projected shape is defined as the length dimension of the second folded ring 7131. In some embodiments, the length dimension of the projected shape of the second folded ring 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 can be 400μm to 800μm. In some embodiments, the length dimension of the projected shape of the second folded ring 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 can be 500μm to 700μm.
在一些實施例中，第二折環7131在平行於增強區域711的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：16至5：8之間。在一些實施例中，第二折環7131在平行於增強區域711的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：8至1：2之間。在一些實施例中，第二折環7131在平行於增強區域711的振動方向的投影平面上投影形狀的高度尺寸與長度尺寸的比值可以位於1：4至3：8之間。 In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the second fold 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 may be between 1:16 and 5:8. In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the second fold 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 may be between 1:8 and 1:2. In some embodiments, the ratio of the height dimension to the length dimension of the projected shape of the second fold 7131 on the projection plane parallel to the vibration direction of the enhanced region 711 may be between 1:4 and 3:8.
在一些實施例中，參見圖14A，第二折環7131的第二彎折方向背離彈性元件710的中部時，第二折環7131沿第二彎折方向的高度尺寸可以小於沿垂直於第二彎折方向的長度尺寸。第二折環7131沿第二彎折方向的高度尺寸小於沿垂直於第二彎折方向的長度尺寸，可以使得增強區域711在垂直於增強區域711的振動方向的平面上具有較大的投影面積，增強區域711振動過程中可以推動更多的空氣振動，進而提高振動組件700的低頻性能。 In some embodiments, referring to FIG. 14A , when the second bending direction of the second folded ring 7131 is away from the middle of the elastic element 710, the height dimension of the second folded ring 7131 along the second bending direction may be smaller than the length dimension along the direction perpendicular to the second bending direction. The height dimension of the second folded ring 7131 along the second bending direction is smaller than the length dimension along the direction perpendicular to the second bending direction, so that the enhanced region 711 has a larger projection area on the plane perpendicular to the vibration direction of the enhanced region 711, and the enhanced region 711 can promote more air vibration during vibration, thereby improving the low-frequency performance of the vibration component 700.
在一些實施例中，參見圖7至圖15，第二折環7131沿垂直於第二彎折方向的長度尺寸與增強區域711在垂直於增強區域711的振動方向上的長度尺寸的比值可以位於1：20至8：25之間。在一些實施例中，第二折環7131沿垂直於第二彎折方向的長度尺寸與增強區域711在垂直於增強區域711的振動方向上的長度尺寸的比值可以位於1：15至4：15之間。在一些實施例中，第二折環7131沿垂直於增強區域711的振動方向的尺寸與增強區域711在垂直於增強區域711的振動方向上的長度尺寸的比值可以位於1：10至1：5之間。在一些實施例中，第二折環 7131沿垂直於增強區域711的振動方向的尺寸與增強區域711在垂直於增強區域711的振動方向上的長度尺寸的比值可以位於1：8至1：6之間。 In some embodiments, referring to FIGS. 7 to 15 , the ratio of the length of the second fold 7131 along the direction perpendicular to the second bending direction to the length of the reinforcement zone 711 in the vibration direction perpendicular to the reinforcement zone 711 may be between 1:20 and 8:25. In some embodiments, the ratio of the length of the second fold 7131 along the direction perpendicular to the second bending direction to the length of the reinforcement zone 711 in the vibration direction perpendicular to the reinforcement zone 711 may be between 1:15 and 4:15. In some embodiments, the ratio of the dimension of the second fold 7131 along the direction perpendicular to the vibration direction of the reinforcement zone 711 to the length of the reinforcement zone 711 in the vibration direction perpendicular to the reinforcement zone 711 may be between 1:10 and 1:5. In some embodiments, the ratio of the dimension of the second fold 7131 along the vibration direction perpendicular to the enhancement region 711 to the length dimension of the enhancement region 711 along the vibration direction perpendicular to the enhancement region 711 may be between 1:8 and 1:6.
需要說明的是，振動組件700的彈性元件710除了可以包括第一預處理區域712和第二預處理區域713外，還可以包括更多預處理區域，例如，圖16至圖18所示的第三預處理區域715、第四預處理區域716等。第三預處理區域715環繞連接於第二預處理區域713的周側，第四預處理區域716環繞連接於第三預處理區域715的周側。彈性元件710包括的預處理區域的數量可以根據振動組件700的需求(例如，預處理區域為增強區域711提供的沿增強區域711的振動方向的位移量)進行設置，本說明書實施例在此不做特別限定。 It should be noted that the elastic element 710 of the vibration assembly 700 may include more pre-processing areas in addition to the first pre-processing area 712 and the second pre-processing area 713, such as the third pre-processing area 715 and the fourth pre-processing area 716 shown in Figures 16 to 18. The third pre-processing area 715 is connected to the periphery of the second pre-processing area 713, and the fourth pre-processing area 716 is connected to the periphery of the third pre-processing area 715. The number of pre-processing areas included in the elastic element 710 can be set according to the requirements of the vibration assembly 700 (for example, the displacement provided by the pre-processing area to the enhancement area 711 along the vibration direction of the enhancement area 711), and the embodiments of this specification are not particularly limited here.
圖19至圖28是根據本說明書的一些實施例所示的振動組件示例性結構圖。 Figures 19 to 28 are exemplary structural diagrams of vibration components according to some embodiments of this specification.
在一些實施例中，參見圖19至圖28，振動組件1900的一個或多個元件(例如，彈性元件1910、增強區域1911、第一預處理區域1912、固定區域1913、第一折環19121等)與圖2至圖6所示的振動組件200的一個或多個元件(例如，彈性元件210、增強區域211、第一預處理區域212、固定區域213、第一折環2121等)可以相同或相似。即振動組件1900可以包括增強區域1911、第一預處理區域1912和固定區域1913。與振動組件200的不同之處在於振動組件1900的支撐元件1920。 In some embodiments, referring to FIGS. 19 to 28 , one or more elements of the vibration assembly 1900 (e.g., elastic element 1910, reinforcement area 1911, first pre-processing area 1912, fixed area 1913, first fold 19121, etc.) may be the same or similar to one or more elements of the vibration assembly 200 shown in FIGS. 2 to 6 (e.g., elastic element 210, reinforcement area 211, first pre-processing area 212, fixed area 213, first fold 2121, etc.). That is, the vibration assembly 1900 may include the reinforcement area 1911, the first pre-processing area 1912, and the fixed area 1913. The difference from the vibration assembly 200 is the support element 1920 of the vibration assembly 1900.
在一些實施例中，參見圖19，振動組件1900的彈性元件1910的固定區域1913位於第一預處理區域1912的週邊，並環繞連接於第一預處理區域1912的周側。支撐元件1920可以位於固定區域1913沿增強區域1911的振動方向的任一表面，並通過固定區域1913與第一預處理區域1912連接。 In some embodiments, referring to FIG. 19 , the fixed area 1913 of the elastic element 1910 of the vibration assembly 1900 is located around the first pre-processing area 1912 and is connected around the first pre-processing area 1912. The supporting element 1920 can be located on any surface of the fixed area 1913 along the vibration direction of the enhancement area 1911 and connected to the first pre-processing area 1912 through the fixed area 1913.
在一些實施例中，支撐元件1920可以包括夾持部1921和形變部1922。在一些實施例中，夾持部1921可以與形變部1922相對設置，固定區域1913 夾持於支撐元件1920的夾持部1921和形變部1922之間。在一些實施例中，支撐元件1920的形變部1922可以通過發生形變為增強區域1911提供沿增強區域1911的振動方向的第三位移量。第三位移量可以是支撐元件1920為增強區域1911在其振動方向上的振動過程中所貢獻的位移大小。在一些實施例中，如圖19所示，支撐元件1920的形變部1922沿增強區域1911的振動方向的初始高度(形變部1922未發生形變時的高度)為H0，當形變部1922回應於振動組件1900的振動訊號進行振動時，形變部1922沿增強區域1911的振動方向可以發生形變，使得形變部1922沿增強區域1911的振動方向的高度增加量(即形變部1922的變形量)為H3。形變部1922沿增強區域1911的振動方向的高度增加量H3，即為形變部1922為增強區域1911提供沿增強區域1911的振動方向的第三位移量。 In some embodiments, the support element 1920 may include a clamping portion 1921 and a deformation portion 1922. In some embodiments, the clamping portion 1921 may be disposed opposite to the deformation portion 1922, and the fixed region 1913 is clamped between the clamping portion 1921 and the deformation portion 1922 of the support element 1920. In some embodiments, the deformation portion 1922 of the support element 1920 may provide the reinforcement region 1911 with a third displacement along the vibration direction of the reinforcement region 1911 by deforming. The third displacement may be the displacement amount contributed by the support element 1920 to the reinforcement region 1911 during the vibration process in the vibration direction thereof. In some embodiments, as shown in FIG. 19 , the initial height of the deformation portion 1922 of the support element 1920 along the vibration direction of the enhanced region 1911 (the height of the deformation portion 1922 when it is not deformed) is H0. When the deformation portion 1922 vibrates in response to the vibration signal of the vibration component 1900, the deformation portion 1922 can be deformed along the vibration direction of the enhanced region 1911, so that the height increase of the deformation portion 1922 along the vibration direction of the enhanced region 1911 (i.e., the deformation amount of the deformation portion 1922) is H3. The height increase H3 of the deformation portion 1922 along the vibration direction of the enhanced region 1911 is the third displacement amount provided by the deformation portion 1922 to the enhanced region 1911 along the vibration direction of the enhanced region 1911.
在一些實施例中，支撐元件1920的形變部1922為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3可以為1μm至50μm。在一些實施例中，支撐元件1920的形變部1922為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3可以為4μm至30μm。 In some embodiments, the third displacement H3 provided by the deformation part 1922 of the support element 1920 for the enhanced region 1911 along the vibration direction of the enhanced region 1911 may be 1 μm to 50 μm. In some embodiments, the third displacement H3 provided by the deformation part 1922 of the support element 1920 for the enhanced region 1911 along the vibration direction of the enhanced region 1911 may be 4 μm to 30 μm.
在一些實施例中，通過設置形變部1922，可以提高支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3，進而提高增強區域1911沿增強區域1911的振動方向的振動位移或振動幅度，從而推動更多的空氣振動，提高振動組件1900的低頻性能。同時，在振動組件1900振動時，第一預處理區域1912和支撐元件1920通過形變將振動衝擊能量以變形能形式分別存儲在第一預處理區域1912和支撐元件1920內部，第一預處理區域1912和支撐元件1920進行多次阻尼衰減運動，進而將較大的振動衝擊能量通過阻尼運動進行消散，避免振動組件1900(尤其是彈性元件1910)在振動時損壞，提高振動組件1900的可靠性。 In some embodiments, by providing the deformation portion 1922, the support element 1920 can provide the third displacement H3 along the vibration direction of the reinforcement region 1911 for the reinforcement region 1911, thereby increasing the vibration displacement or vibration amplitude of the reinforcement region 1911 along the vibration direction of the reinforcement region 1911, thereby driving more air vibrations and improving the low-frequency performance of the vibration assembly 1900. At the same time, when the vibration component 1900 vibrates, the first pre-processed area 1912 and the supporting element 1920 store the vibration impact energy in the form of deformation energy in the first pre-processed area 1912 and the supporting element 1920 respectively through deformation. The first pre-processed area 1912 and the supporting element 1920 perform multiple damping attenuation movements, thereby dissipating the larger vibration impact energy through damping movements, avoiding damage to the vibration component 1900 (especially the elastic element 1910) during vibration, and improving the reliability of the vibration component 1900.
在一些實施例中，支撐元件1920也可以不包括夾持部1921，將彈 性元件1910的固定區域1913可以直接與形變部1922連接(如膠黏等)。 In some embodiments, the supporting element 1920 may not include the clamping portion 1921, and the fixed area 1913 of the elastic element 1910 may be directly connected to the deformation portion 1922 (such as by gluing, etc.).
在一些實施例中，第一預處理區域1912為增強區域1911提供沿增強區域1911的振動方向的第一位移量H1與形變部1922為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3的比值可以為1：50至50：1。在一些實施例中，第一位移量H1與第三位移量H3的比值可以為1：1至2：1。 In some embodiments, the ratio of the first displacement H1 provided by the first pre-processing area 1912 to the enhanced area 1911 along the vibration direction of the enhanced area 1911 and the third displacement H3 provided by the deformation part 1922 to the enhanced area 1911 along the vibration direction of the enhanced area 1911 can be 1:50 to 50:1. In some embodiments, the ratio of the first displacement H1 to the third displacement H3 can be 1:1 to 2:1.
在一些實施例中，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3與支撐元件1920沿增強區域1911的振動方向的斷裂伸長率可以成正相關。在一些實施例中，支撐元件1920沿增強區域1911的振動方向的斷裂伸長率越大，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3越大。在一些實施例中，支撐元件1920沿增強區域1911的振動方向的斷裂伸長率可以為5%至800%。在一些實施例中，支撐元件1920沿增強區域1911的振動方向的斷裂伸長率可以為10%至600%。在一些實施例中，支撐元件1920沿增強區域1911的振動方向的斷裂伸長率可以為50%至400%。 In some embodiments, the third displacement H3 provided by the support element 1920 for the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 may be positively correlated with the fracture elongation of the support element 1920 along the vibration direction of the reinforcement region 1911. In some embodiments, the greater the fracture elongation of the support element 1920 along the vibration direction of the reinforcement region 1911, the greater the third displacement H3 provided by the support element 1920 for the reinforcement region 1911 along the vibration direction of the reinforcement region 1911. In some embodiments, the fracture elongation of the support element 1920 along the vibration direction of the reinforcement region 1911 may be 5% to 800%. In some embodiments, the elongation at break of the support element 1920 along the vibration direction of the reinforcement area 1911 may be 10% to 600%. In some embodiments, the elongation at break of the support element 1920 along the vibration direction of the reinforcement area 1911 may be 50% to 400%.
在一些實施例中，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3，與支撐元件1920的硬度可以成負相關。在一些實施例中，支撐元件1920的硬度越大，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3越小。在一些實施例中，支撐元件1920的硬度可以為邵爾A小於90度。在一些實施例中，支撐元件1920的硬度可以為邵爾A小於80度。 In some embodiments, the third displacement H3 provided by the support element 1920 for the reinforcement area 1911 along the vibration direction of the reinforcement area 1911 may be negatively correlated with the hardness of the support element 1920. In some embodiments, the greater the hardness of the support element 1920, the smaller the third displacement H3 provided by the support element 1920 for the reinforcement area 1911 along the vibration direction of the reinforcement area 1911. In some embodiments, the hardness of the support element 1920 may be less than 90 degrees Shore A. In some embodiments, the hardness of the support element 1920 may be less than 80 degrees Shore A.
在一些實施例中，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3，與支撐元件1920的拉伸強度可以成負相關。在一些實施例中，支撐元件1920的拉伸強度越大，支撐元件1920為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3越小。在一些實施例中，支撐 元件1920的拉伸強度可以為0.5MPa至100MPa。在一些實施例中，支撐元件1920的拉伸強度可以為1MPa至50MPa。在一些實施例中，支撐元件1920的拉伸強度可以為0.5MPa至10MPa。 In some embodiments, the third displacement H3 provided by the support element 1920 for the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 may be negatively correlated with the tensile strength of the support element 1920. In some embodiments, the greater the tensile strength of the support element 1920, the smaller the third displacement H3 provided by the support element 1920 for the reinforcement region 1911 along the vibration direction of the reinforcement region 1911. In some embodiments, the tensile strength of the support element 1920 may be 0.5MPa to 100MPa. In some embodiments, the tensile strength of the support element 1920 may be 1MPa to 50MPa. In some embodiments, the tensile strength of the support element 1920 may be 0.5MPa to 10MPa.
在一些實施例中，為了提高支撐元件1920為增強區域1911提供的沿增強區域1911的振動方向的第三位移量H3，可以設置支撐元件1920(特別是形變部1922)的結構，使得支撐元件1920在垂直於增強區域1911的振動方向的橫截面沿增強區域1911的振動方向具有不同的截面面積，具體參見圖20至圖26的相關描述。 In some embodiments, in order to increase the third displacement H3 provided by the support element 1920 for the enhanced region 1911 along the vibration direction of the enhanced region 1911, the structure of the support element 1920 (especially the deformation portion 1922) can be set so that the cross section of the support element 1920 perpendicular to the vibration direction of the enhanced region 1911 has different cross-sectional areas along the vibration direction of the enhanced region 1911, see the relevant description of Figures 20 to 26 for details.

In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcement region 1911 has different cross-sectional areas along the vibration direction of the reinforcement region 1911, the third displacement H3 provided by the support element 1920 for the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 may be 4 μm to 70 μm. In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the enhanced region 1911 has different cross-sectional areas along the vibration direction of the enhanced region 1911, the third displacement H3 provided by the support element 1920 for the enhanced region 1911 along the vibration direction of the enhanced region 1911 may be 5μm to 50μm.

在一些實施例中，通過將支撐元件1920設置為孔洞結構，可以提高支撐元件1920沿增強區域1911的振動方向的形變能力，進而提高支撐元件1920為增強區域1911提供的沿增強區域1911的振動方向的第三位移量H3。 In some embodiments, by setting the support element 1920 as a hole structure, the deformation capacity of the support element 1920 along the vibration direction of the enhanced region 1911 can be improved, thereby increasing the third displacement H3 provided by the support element 1920 for the enhanced region 1911 along the vibration direction of the enhanced region 1911.

在一些實施例中，參見圖27和圖28，振動組件1900的支撐元件1920可以與第二預處理區域1914連接。具體地，彈性元件1910的固定區域1913位於第二預處理區域1914的週邊，並環繞連接於第二預處理區域1914的周側。支撐元件1920可以位於固定區域1913沿增強區域1911的振動方向的任一表面，並通過固定區域1913與第二預處理區域1914連接。第二預處理區域1914可以為增強區域1911提供沿增強區域1911的振動方向的第二位移量。 In some embodiments, referring to FIG. 27 and FIG. 28 , the support element 1920 of the vibration assembly 1900 may be connected to the second pre-processing area 1914. Specifically, the fixed area 1913 of the elastic element 1910 is located around the second pre-processing area 1914 and is connected around the second pre-processing area 1914. The support element 1920 may be located on any surface of the fixed area 1913 along the vibration direction of the enhancement area 1911, and is connected to the second pre-processing area 1914 through the fixed area 1913. The second pre-processing area 1914 may provide the enhancement area 1911 with a second displacement along the vibration direction of the enhancement area 1911.
在一些實施例中，參見圖27，支撐元件1920沿增強區域1911的振動方向上可以不產生形變，即支撐元件1920可以不為增強區域1911提供沿增強區域1911的振動方向的第三位移量H3。這種設置方式下，在振動組件1900的振動過程中，第一預處理區域1912為增強區域1911提供沿增強區域1911的振動方向的第一位移量H1。彈性元件1910的第二預處理區域1914為增強區域1911提供沿增強區域1911的振動方向的第二位移量H2。第一位移量H1和第二位移量H2疊加構成增強區域1911沿增強區域1911的振動方向的振動位移或振動幅度。 In some embodiments, see FIG. 27 , the support element 1920 may not be deformed along the vibration direction of the enhanced region 1911, that is, the support element 1920 may not provide the enhanced region 1911 with a third displacement H3 along the vibration direction of the enhanced region 1911. In this setting, during the vibration process of the vibration assembly 1900, the first pre-processed region 1912 provides the enhanced region 1911 with a first displacement H1 along the vibration direction of the enhanced region 1911.

在一些實施例中，通過在振動組件1900中設置第一預處理區域1912、第二預處理區域1914、支撐元件1920(形變部1922)，可以提高增強區域 1911沿增強區域1911的振動方向的振動位移或振動幅度(包括第一位移量H1、第二位移量H2、第三位移量H3)。增強區域1911在其振動方向上的振動位移或振動幅度的提高，一方面，可以使得振動組件1900進行較大幅度的振動時，第一預處理區域1912、第二預處理區域1914、支撐元件1920分別通過形變將振動衝擊能量以變形能形式分別存儲在第一預處理區域1912、第二預處理區域1914、支撐元件1920內部，第一預處理區域1912、第二預處理區域1914、支撐元件1920進行多次阻尼衰減運動，進而將較大的振動衝擊能量通過阻尼運動進行消散，避免振動組件1900(尤其是彈性元件1910)在較大幅度振動時損壞，提高振動組件1900的可靠性。另一方面，增強區域1911在其振動方向上的振動位移或振動幅度的提高，可以使得增強區域1911振動過程中能推動更多的空氣振動，進而提高振動組件1900的低頻性能。 In some embodiments, by providing the first pre-processing area 1912, the second pre-processing area 1914, and the supporting element 1920 (deformation portion 1922) in the vibration assembly 1900, the vibration displacement or vibration amplitude (including the first displacement amount H1, the second displacement amount H2, and the third displacement amount H3) of the enhanced area 1911 along the vibration direction of the enhanced area 1911 can be increased. The increase in the vibration displacement or vibration amplitude of the enhanced area 1911 in its vibration direction can, on the one hand, enable the first pre-processing area 1912, the second pre-processing area 1914, and the supporting element 1920 to store the vibration impact energy in the form of deformation energy in the first pre-processing area 1912, the second pre-processing area 1914, and the supporting element 1920 respectively through deformation when the vibration assembly 1900 vibrates with a relatively large amplitude. 1914, inside the supporting element 1920, the first pre-processed area 1912, the second pre-processed area 1914, and the supporting element 1920 perform multiple damping attenuation movements, thereby dissipating the larger vibration impact energy through the damping movement, avoiding damage to the vibration component 1900 (especially the elastic element 1910) when vibrating with a larger amplitude, and improving the reliability of the vibration component 1900. On the other hand, the increase in the vibration displacement or vibration amplitude of the enhanced area 1911 in its vibration direction can enable the enhanced area 1911 to push more air vibrations during the vibration process, thereby improving the low-frequency performance of the vibration component 1900.

When the supporting element 30212 is embedded in the inner wall of the housing 3010, a hole matching the supporting element 30212 may be provided on the inner wall of the housing 3010, so that the supporting element 30212 can be placed in the hole to achieve the embedding of the supporting element 30212. In some embodiments, referring to FIG. 31 , the support element 30212 may also be disposed in the cavity formed by the housing 3010, and the support element 30212 is connected to the housing 3010 along the lower surface (the surface close to the drive unit 3022) or the lateral surface of the vibration component 3021 in the vibration direction to support the elastic element 30211. When the support element 30212 is disposed in the cavity formed by the housing 3010, the inner wall of the housing 3010 may be configured to have a protruding structure matching the support element 30212, so that the support element 30212 may be disposed on the surface of the protruding structure along the vibration direction to achieve the connection between the support element 30212 and the housing 3010. In this arrangement, by placing the support element 30212 in the cavity formed by the housing 3010, the support element 30212 can be prevented from being scratched and damaged during the use of the speaker 3000, thereby preventing the speaker 3000 (especially the vibration component 3021) from being damaged.

In some embodiments, the speaker 3000 can be a small-sized MEMS speaker or a micro speaker. In some embodiments, the greater the vibration displacement or vibration amplitude of the enhanced area 30211A along the vibration direction of the enhanced area 30211A, the greater the change in the volume of the first cavity 3030 (i.e., the stronger the air vibration in the first cavity 3030), and the better the low-frequency performance of the speaker 3000 (such as the greater the low-frequency sensitivity).
在一些實施例中，可以設計振動組件3021(彈性元件30211、支撐元件30212)的結構，以提高增強區域30211A沿增強區域30211A的振動方向的振動位移或振動幅度。在一些實施例中，參見圖30至圖31，振動組件3021的彈性元件30211可以包括第一預處理區域30211B，第一預處理區域30211B可以包括第一折環，第一折環具有第一彎折方向。第一折環在彈性元件30211振動過程中可以產生形變，使第一預處理區域30211B為增強區域30211A提供沿增強區域 30211A的振動方向的第一位移量，從而提高增強區域30211A沿增強區域30211A的振動方向的振動幅度或振動位移。關於第一預處理區域30211B和第一折環的具體內容可以參見本說明書其它地方的描述。 In some embodiments, the structure of the vibration assembly 3021 (elastic element 30211, supporting element 30212) can be designed to increase the vibration displacement or vibration amplitude of the enhanced region 30211A along the vibration direction of the enhanced region 30211A.

The first fold can be deformed during the vibration of the elastic element 30211, so that the first pre-processed area 30211B provides the enhanced area 30211A with a first displacement along the vibration direction of the enhanced area 30211A, thereby increasing the vibration amplitude or vibration displacement of the enhanced area 30211A along the vibration direction of the enhanced area 30211A.

The second pre-processing region may be disposed around the first pre-processing region 30211B, and the second pre-processing region may provide the enhancement region 30211A with a second displacement along the vibration direction of the enhancement region 30211A. In some embodiments, the second pre-processing region may include a second fold, and the second fold has a second bending direction. The second bending direction is the same as or different from the first bending direction. The second fold can be deformed during the vibration of the elastic element 30211, so that the second pre-processed area provides the enhanced area 30211A with a second displacement along the vibration direction of the enhanced area 30211A, thereby increasing the vibration amplitude or vibration displacement of the enhanced area 30211A along the vibration direction of the enhanced area 30211A.

在一些實施例中，振動組件3021的彈性元件30211還可以包括更多個預處理區域，例如，第三預處理區域、第四預處理區域等。第三預處理區域環繞連接於第二預處理區域的周側，第四預處理區域環繞連接於第三預處理區域的周側。彈性元件30211包括的預處理區域的數量可以根據揚聲器3000的需求(例如，低頻靈敏度)進行設置，本說明書實施例在此不做特別限定。 In some embodiments, the elastic element 30211 of the vibration component 3021 may also include more pre-processing areas, for example, a third pre-processing area, a fourth pre-processing area, etc. The third pre-processing area is connected to the periphery of the second pre-processing area, and the fourth pre-processing area is connected to the periphery of the third pre-processing area. The number of pre-processing areas included in the elastic element 30211 can be set according to the requirements of the speaker 3000 (for example, low-frequency sensitivity), and the embodiments of this specification are not particularly limited here.
