Description
本發明提供了一種音柱結構，尤指一種安裝於樂器音箱內部，並可以有效解決低音繞射、迴音與殘響問題的音柱結構。 The invention provides a sound column structure, in particular to a sound column structure which is installed inside a musical instrument speaker and can effectively solve the problems of bass diffraction, echo and reverberation.
無論在西方或是東方文化中，音樂相關的領域裡，許多樂器都具有音箱的結構，可以協助調整樂器的音質及音量。舉凡許多電子樂器、打擊樂器或弦樂器等皆具有類似的音箱結構。 Whether in the Western or Eastern culture, in music-related fields, many instruments have a speaker structure that can help adjust the sound quality and volume of the instrument. Many electronic, percussion or string instruments have similar speaker structures.
在如此眾多的樂器種類中，弦樂器佔有相當重要的地位。其中西方又以提琴類的樂器最為著名，甚至連現代東方的國樂也都引進西方的大提琴，作為低音演奏的要角之一。一般提琴類的弦樂器結構主要由不同曲度的木板拼湊而成，而音柱便是在這種木板拼湊的音箱中，影響弦樂器音質及音量的重要角色。 Among such a large number of musical instruments, stringed instruments occupy a very important position. Among them, the Western is also famous for its violin-like instruments. Even the modern Oriental music has introduced Western cello as one of the main characters of bass performance. Generally, the stringed instrument structure of the violin is mainly made up of different degrees of wood, and the column is an important role in the sound quality and volume of the stringed instrument.
通常，在一個弦樂器的音箱中，主要由頂板、底板以及側板組成一個音箱。如提琴類的樂器，其頂板與底板便存在一個曲度的變化。而音柱就是被封固在頂板與背板之間。 Usually, in a stringed instrument speaker, a speaker is mainly composed of a top plate, a bottom plate, and a side plate. For a violin-like instrument, there is a change in curvature between the top and bottom plates. The sound column is sealed between the top plate and the back plate.
有關音柱的設置位置，一般提琴類的樂器主要設在琴橋座下方的區域中。琴橋通常是由一片特殊形狀的木片製成，主要將弦的震動傳 遞到音箱中，以發出聲響。傳統的製程中，音柱是一種木製圓柱體，以其兩端之長度和形狀適配到音箱中，並頂住頂板及底板。由於頂板及底板通常具有一定的曲度，因此在安裝音柱的過程中，通常必須不斷的切削音柱的兩端，以適配頂板及底板在音箱中產生的形狀。 Regarding the setting position of the sound column, the general violin musical instrument is mainly located in the area below the bridge seat. The bridge is usually made of a piece of wood with a special shape, which mainly transmits the vibration of the string. Handed into the speaker to make a sound. In the traditional process, the sound column is a wooden cylinder that fits into the speaker with its length and shape at both ends, and against the top and bottom plates. Since the top plate and the bottom plate usually have a certain curvature, in the process of installing the sound column, it is usually necessary to continuously cut both ends of the sound column to adapt the shape generated by the top plate and the bottom plate in the sound box.
音柱可以有效改善弦樂器之穩定度和聲音性質。如以提琴而言，音柱的安裝僅能透過音箱唯一的開口，即f音孔(f-hole)安裝之。因此以人工的方式削切音柱，並逐步將之安裝入弦樂器的音箱內，實屬費時又費工之工藝。因此，後有人研發出可以將音柱導入f音孔(f-hole)後，再加以調節音柱長短或其兩端適配音箱中頂板及底板曲度的音柱結構。 The sound column can effectively improve the stability and sound properties of the stringed instrument. For violins, the installation of the sound column can only be installed through the speaker's only opening, the f-hole. Therefore, it is time-consuming and labor-intensive to cut the sound column in an artificial manner and gradually install it into the speaker of the stringed instrument. Therefore, some people have developed a sound column structure that can be used to introduce a sound column into an f-hole, and then adjust the length of the sound column or its two ends to fit the top plate and the bottom plate curvature of the speaker.
但相較於傳統一體成形的音柱而言，該種結構對於聲音的影響甚鉅。除了令弦樂器無法發出原本的聲音之外，更衍生出了許多諸如低音繞射、迴音與殘響等問題。 However, this kind of structure has a great influence on the sound compared with the traditional integrally formed column. In addition to making the stringed instrument unable to make the original sound, there are many problems such as bass diffraction, echo and reverberation.

為能瞭解本發明的技術特徵及實用功效，並可依照說明書的內容來實施，茲進一步以如圖式所示的較佳實施例，詳細說明如後：請同時參照圖1以及圖2，圖1係本發明實施例之結構示意圖；圖2係本發明實施例之結構剖面示意圖。圖1及圖2中所展示的實施例為本發明之第一實施例，詳細說明如後。 In order to understand the technical features and practical effects of the present invention, and can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiment as shown in the following figure: Please refer to FIG. 1 and FIG. 2 simultaneously. 1 is a schematic structural view of an embodiment of the present invention; and FIG. 2 is a schematic cross-sectional view of a structure of an embodiment of the present invention. The embodiment shown in Figures 1 and 2 is a first embodiment of the present invention, and the detailed description is as follows.
實施例1Example 1
如圖1及圖2所示，圖1及圖2中之實施例展示了一種音柱結構10，包含二螺柱(100a、100b)、音柱本體200、二球頭柱400、二蓋體500以及至少一調整件300。 As shown in FIG. 1 and FIG. 2, the embodiment in FIGS. 1 and 2 shows a sound column structure 10 including two studs (100a, 100b), a column body 200, a two-ball column 400, and two covers. 500 and at least one adjustment member 300.
本實施例中，音柱本體200的兩端與螺柱100a及螺柱100b連接。螺柱100a較螺柱100b的長度長，且其長度比為13：9。本實施例之螺柱100a及螺柱100b上面具有螺紋，可以與具有中空螺紋結構402的音柱本體200咬合連接。此外，在本實施例中，球頭柱400中亦具有前述中空螺紋結構402。 In this embodiment, both ends of the column body 200 are connected to the stud 100a and the stud 100b. The stud 100a is longer than the stud 100b and has a length ratio of 13:9. The stud 100a and the stud 100b of the present embodiment have threads on the upper surface thereof, and can be engaged with the column body 200 having the hollow thread structure 402. In addition, in the present embodiment, the ball stud 400 also has the aforementioned hollow thread structure 402.
本實施例之螺柱100a及螺柱100b扮演整個音柱結構10中傳遞聲音的重要角色，其材質會與至少一調整件300及球頭柱400中的結構影響整個樂器的聲音表現。 The stud 100a and the stud 100b of the present embodiment play an important role in transmitting sound in the entire column structure 10, and the material thereof and the structure in the at least one adjusting member 300 and the ball stud 400 affect the sound performance of the entire instrument.
而本實施例中，二個球頭柱400依序設於螺柱100a及螺柱100b相對於音柱本體200的另一端，且每個球頭柱400中具有響室403(可參照圖2)。至於二個蓋體500依序設於二個球頭柱400上，而至少一調整件300則設於螺柱100a及螺柱100b上。 In this embodiment, the two ball studs 400 are sequentially disposed on the other end of the stud 100a and the stud 100b with respect to the column body 200, and each of the ball studs 400 has a sounding chamber 403 (refer to FIG. 2) ). The two cover bodies 500 are sequentially disposed on the two ball studs 400, and the at least one adjusting member 300 is disposed on the studs 100a and the studs 100b.
如圖2所示，本實施例中之球頭柱400實質內部包含有中空螺紋結構402及響室403，且中空螺紋結構402與響室403接通。更具體來說，本實施例之中空螺紋結構402與響室403係以一體成型的方式接通。響室403可以依照需求設置為不同體積或形狀的空腔。例如圓柱體空腔、六角柱體空腔或是其他幾何圖形柱體之空腔。 As shown in FIG. 2, the ball stud 400 of the present embodiment substantially includes a hollow thread structure 402 and a sound chamber 403, and the hollow thread structure 402 is connected to the sound chamber 403. More specifically, the hollow thread structure 402 of the present embodiment is coupled to the sound chamber 403 in an integrally formed manner. The chamber 403 can be provided as a cavity of a different volume or shape as desired. For example, a cylindrical cavity, a hexagonal cylinder cavity, or a cavity of other geometric cylinders.
本實施例中之響室主要係配合至少一調整件300、螺柱100a及螺柱100b間的交互關係，以可調式體積涵洞(adjustable resonance room)的原理調整球頭柱400內部體積，改變整個樂器音箱中的共振頻率(resonant frequency)。換言之，由中空螺紋結構402與響室403一體成型接通的結構可以讓使用者調整樂器最佳的音頻、音質等相關發聲條件，達到最佳且最適配化於各種樂器的音柱結構10。 The sound chamber in this embodiment is mainly matched with the interaction relationship between at least one adjusting member 300, the stud 100a and the stud 100b, and the adjustable volume culvert (adjustable resonance) The principle of room) adjusts the internal volume of the ball stud 400 and changes the resonant frequency in the entire instrumental speaker. In other words, the structure in which the hollow thread structure 402 is integrally formed with the sound chamber 403 allows the user to adjust the sound, sound quality and other related sounding conditions of the instrument to achieve the best and most suitable sound column structure 10 for various instruments.
此外，本實施例中之球頭柱400包含一球型關節，且球型關節上更設有磁力元件401。請同時參照圖1及圖5，圖5係本發明施裝於提琴中之結構剖面示意圖。當音柱結構10裝設於提琴V中時，磁力元件401可以用來作為微調音柱結構10或確認其位置的手段。而磁力元件401可以依據需要選用永久磁鐵等具有磁力的元件，本發明並不加以限制。 In addition, the ball stud 400 in this embodiment includes a ball joint, and the ball joint is further provided with a magnetic element 401. Please refer to FIG. 1 and FIG. 5 simultaneously. FIG. 5 is a schematic cross-sectional view showing the structure of the present invention applied to the violin. When the fret structure 10 is mounted in the violin V, the magnetic element 401 can be used as a means of fine tuning the column structure 10 or confirming its position. On the other hand, the magnetic element 401 can select a magnetic element such as a permanent magnet as needed, and the invention is not limited thereto.
本實施例中之磁力元件401可以包埋於球頭柱400之球型關節之中，亦可以透過鑲嵌的手段讓部分磁力元件401部分裸露於球型關節之外。至於與球頭柱400之球型關節相應設置的元件則為蓋體500。本實施例中，二個蓋體500上具有球型凹槽，所述球型凹槽相應卡合球頭柱400上的球型關節，且每個蓋體500上更設有止滑墊。 The magnetic element 401 in this embodiment may be embedded in the spherical joint of the ball stud 400, and part of the magnetic element 401 may be exposed outside the spherical joint by means of inlaying. As for the component provided corresponding to the spherical joint of the ball stud 400, the cover 500 is used. In this embodiment, the two cover bodies 500 have spherical recesses, and the spherical recesses respectively engage the spherical joints on the ball studs 400, and each of the cover bodies 500 further has a slip preventing pad.
在本實施例中，蓋體500係直接與音箱之頂板與底板接觸之元件。其特徵在於相對於球型凹槽之一側呈現較平但卻帶有略為曲面的圓扁碟狀結構，得以適配具有略為曲度的音箱頂板與底板。而止滑墊的設置可以設於球型凹槽中，亦可以設於相對於球型凹槽之一側呈現較平但卻帶有略為曲面的圓扁碟狀結構上。止滑墊的設置有助於增加蓋體500與球頭柱400或音箱頂板與底板的摩擦力，減少整體音柱結構10位移或是脫落的風險。 In the present embodiment, the cover 500 is an element that directly contacts the top and bottom plates of the speaker. The utility model is characterized in that a flat plate-like structure with a flat surface but a slightly curved surface is provided on one side of the spherical groove, and the top plate and the bottom plate of the speaker having a slight curvature are adapted. The arrangement of the anti-slip mat may be disposed in the spherical groove, or may be disposed on a flat dish-like structure which is relatively flat but has a slightly curved surface with respect to one side of the spherical groove. The arrangement of the anti-slip pad helps to increase the friction between the cover 500 and the ball stud 400 or the top plate and the bottom plate of the speaker, and reduces the risk of displacement or falling of the overall column structure 10.
而至少一調整件300的作用係配合螺柱100a、螺柱100b、 音柱本體200以及球頭柱400中的中空螺紋結構402與響室403，調整整體音柱結構10之長度以及音箱的共振頻率。 The function of the at least one adjusting member 300 is matched with the stud 100a, the stud 100b, The column body 200 and the hollow thread structure 402 and the chamber 403 in the ball stud 400 adjust the length of the overall column structure 10 and the resonant frequency of the speaker.
本實施例中，每個調整件300設計為多齒狀。更精確來說，為了方便調整音柱結構10之長度以及音箱的共振頻率，調整件300之多齒狀結構刻意做出每一齒之間具有圓弧內凹的機構設計，讓調整器具可以更有效的抓住調整件300，以透過轉動調整其固定於螺柱100a、螺柱100b上的位置；並調正調整件300緊抵音柱本體200或球頭柱400的靠攏緊實程度，達到調整整體音柱結構10之長度以及音箱的共振頻率之功效。 In this embodiment, each of the adjusting members 300 is designed in a multi-tooth shape. More precisely, in order to conveniently adjust the length of the column structure 10 and the resonant frequency of the speaker, the multi-tooth structure of the adjusting member 300 deliberately makes a mechanism design with a circular arc between each tooth, so that the adjusting device can be more The adjusting member 300 is effectively grasped to adjust the position fixed to the stud 100a and the stud 100b by rotating; and the tightness of the adjusting member 300 against the column body 200 or the ball stud 400 is adjusted. Adjust the length of the overall column structure 10 and the resonant frequency of the speaker.
本實施例中，調整件300緊抵音柱本體200或球頭柱400的靠攏緊實程度亦會影響到中空螺紋結構402與響室403對於樂器聲音表現的狀態。因此，本實施例以兩個調整件300作為一上一下的緊抵實施樣態，係為讓使用者對於本實施例之音柱結構10保有最大的調整自由度。 In this embodiment, the tightness of the adjustment member 300 against the column body 200 or the ball stud 400 also affects the state of the hollow thread structure 402 and the sound chamber 403 for the sound performance of the instrument. Therefore, in this embodiment, the two adjusting members 300 are used as a top-down embodiment, so that the user can maintain the maximum adjustment degree of freedom for the sound column structure 10 of the embodiment.
而在本實施例中的球頭柱400或蓋體500上更設有內凹曲面結構600。所述內凹曲面結構600可以透過車床加工等形式製作，本發明並不加以限制。所述的內凹曲面結構600可以有效的美化整體音柱結構10之外觀，並具有減輕音柱結構10重量的功效。此外，對於音柱本身的共鳴效果也具有一定的幫助。 In the embodiment, the ball stud 400 or the cover 500 is further provided with a concave curved structure 600. The concave curved structure 600 can be fabricated by lathe processing or the like, and the invention is not limited thereto. The concave curved structure 600 can effectively enhance the appearance of the overall sound column structure 10 and has the effect of reducing the weight of the sound column structure 10. In addition, it also helps the resonance of the sound column itself.
在其他可能的實施樣態中，本實施例之螺柱100a、螺柱100b或調整件300上更鍍有一陽極氧化金屬鍍膜。所述陽極氧化金屬鍍膜之材質可以用金、鈦或鎂鋰合金製作。更精確來說可以透過100奈米外部金屬陣列處理(如陽極氧化處理等表面處理技術)等手段製作。當選用金(Au)作為材質時，可採用14K金作為原料，鈦(Ti)則可以是純鈦或是鈦合金等， 本發明並不加以限制。 In other possible implementations, the stud 100a, the stud 100b or the adjusting member 300 of the embodiment is further plated with an anodized metal plating film. The material of the anodized metal plating film can be made of gold, titanium or magnesium lithium alloy. More precisely, it can be fabricated by means of 100 nm external metal array processing (such as surface treatment technology such as anodizing). When gold (Au) is used as the material, 14K gold can be used as the raw material, and titanium (Ti) can be pure titanium or titanium alloy. The invention is not limited.
實施例2Example 2
請同時參照圖3及圖4，圖3係本發明另一實施例之結構示意圖；圖4係本發明另一實施例之結構剖面示意圖。圖3及圖4中展示了本發明另一種實施樣態的音柱結構10。在圖3及圖4中所示之音柱結構10包含螺柱100、音柱本體200、球頭柱400、二個蓋體500以及至少一調整件300。其中音柱本體200與螺柱100連接，且音柱本體200相對螺柱100連接之另一端設有球型關節。 3 and FIG. 4, FIG. 3 is a schematic structural view of another embodiment of the present invention; and FIG. 4 is a schematic cross-sectional view showing another embodiment of the present invention. A sound column structure 10 of another embodiment of the present invention is illustrated in Figures 3 and 4. The sound column structure 10 shown in FIGS. 3 and 4 includes a stud 100, a column body 200, a ball stud 400, two covers 500, and at least one adjusting member 300. The column body 200 is connected to the stud 100, and the other end of the column body 200 connected to the stud 100 is provided with a spherical joint.
而球頭柱400設於螺柱100相對於音柱本體200的另一端，且球頭柱400中具有響室403，兩個蓋體500則依序設於球頭柱400及音柱本體200之球型關節上。而至少一調整件300則設於該螺柱上。 The ball stud 400 is disposed on the other end of the stud 100 relative to the column body 200, and the ball stud 400 has a ring chamber 403, and the two cap bodies 500 are sequentially disposed on the ball stud 400 and the column body 200. On the ball joint. At least one adjusting member 300 is disposed on the stud.
本實施例與實施例1中之音柱結構差異為將球頭柱400以及螺柱100的數量縮減至一個。並且將實施例1中之球頭柱400與音柱本體200一體成形為具有球型關節結構的音柱本體200。 The difference in the structure of the sound column in this embodiment and the embodiment 1 is to reduce the number of the ball studs 400 and the studs 100 to one. Further, the ball stud 400 of the first embodiment is integrally formed with the column body 200 into a column body 200 having a spherical joint structure.
因此，在本實施例中，球頭柱400、音柱本體200或蓋體500上更設有內凹曲面結構600之外，也僅有單個球頭柱400中的中空螺紋結構402與響室403接通。本實施例中之音柱結構10具有和實施例1中之音柱結構類似的功效及結構。但實施例2中之音柱結構10主要係因音柱本體200具有較大的體積，可以更有效的調整中空螺紋結構402與響室403a的配比及空間。 Therefore, in the present embodiment, the ball stud 400, the column body 200 or the cover 500 is further provided with a concave curved structure 600, and only the hollow thread structure 402 and the sound chamber in the single ball stud 400 are included. 403 is turned on. The column structure 10 in this embodiment has similar functions and structures as the column structure in the embodiment 1. However, the sound column structure 10 in the second embodiment is mainly because the sound column body 200 has a large volume, and the ratio and space of the hollow screw structure 402 and the sound chamber 403a can be more effectively adjusted.
因此，如果樂器的音箱需要使用響室403a空間較大，或是要將球頭柱400中之響室403與音柱本體200中之響室403a空間大小差 異、形狀或比例設置為較大差異的情況下，可以選用本發明實施例2中的實施樣態。因此，本發明實施例1或實施例2中所載之音柱結構10可以如圖5所示一般，安裝於提琴V之中。當然，本發明所載之音柱結構10並不以提琴V作為唯一可以實施之樂器，其餘如電子樂器、打擊樂器或弦樂器等可以適用音柱構造的樂器，應一併包含於本發明的實施範圍之內。 Therefore, if the speaker of the instrument needs to use the sound chamber 403a to have a large space, or the space between the sound chamber 403 in the ball stud 400 and the sound chamber 403a in the sound column body 200 is small. In the case where the difference, the shape, or the ratio is set to a large difference, the embodiment in the second embodiment of the present invention can be selected. Therefore, the sound column structure 10 contained in Embodiment 1 or Embodiment 2 of the present invention can be mounted in the violin V as shown in FIG. Of course, the sound column structure 10 of the present invention does not use the violin V as the only instrument that can be implemented, and the rest of the instrument, such as an electronic musical instrument, a percussion instrument, or a stringed instrument, which can be applied to the structure of the sound column, should be included in the implementation of the present invention. Within the scope.
惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即依本發明申請專利範圍及說明內容所作之簡單的等效變化與修飾，皆仍屬本發明涵蓋之範圍內。 However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications according to the scope and description of the present invention remain It is within the scope of the present invention.
