Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The loudspeaker comprises a magnetic circuit system and a vibration system, wherein the magnetic circuit system comprises a voice coil, the vibration system comprises an elastic wave, the voice coil is connected with the elastic wave, and the voice coil cuts a magnetic induction line in a magnetic field to drive the elastic wave connected with the voice coil to vibrate.

However, in the related art, since the elastic wave has a certain ductility, so that the structural strength of the elastic wave is weak, and the supporting capability of the elastic wave on the voice coil of the speaker is weak, the elastic wave has a nonlinear problem (such as loss or deformation) caused by insufficient stress of the elastic wave in the vibration process, and the distortion phenomenon of the speaker is increased.

Therefore, how to reduce the non-linearity problem caused by insufficient stress of the elastic wave in the elastic wave vibration process to improve the sound quality of the loudspeaker is a problem to be solved.

In order to solve the above technical problem, please refer to fig. 1, a first aspect of the present application provides a composite damper 1, which can improve the overall rigidity of the composite damper 1, and effectively reduce the loss and deformation caused by insufficient stress during the vibration process of the composite damper 1, thereby effectively improving the sound quality of the speaker 2.

The composite damper 1 comprises a damper body 11 and a support member 12, wherein the damper body 11 is provided with a first through hole 111, the support member 12 is provided with a second through hole 1211, the wall surface of the second through hole 1211 is used for being connected with a voice coil 21 of a loudspeaker 2 when the support member 12 is used, the support member 12 is in bonding fit with the wall surface of the first through hole 111, and the rigidity of the support member 12 is greater than that of the damper body 11.

The detailed structure of the composite damper 1 will be described with reference to fig. 1 to 4, and the composite damper 1 includes a damper body 11 and a support 12.

As shown in fig. 1 and 2, the damper body 11 is a member for allowing the voice coil 21 of the speaker 2 to freely move up and down in the magnetic gap without moving laterally in the composite damper 1 in use, and a specific structure of the damper body 11 will be described later.

The support member 12 serves as a structure for reinforcing the structural strength of the damper body 11 in the composite damper 1 to assist the damper body 11 in being used for connecting with the voice coil 21 of the speaker 2, and a detailed structure of the support member 12 will be described later.

The rigidity of the supporting member 12 is greater than that of the damper body 11, wherein "rigidity" is a term of art in physics and refers to the local deformation resistance of the material of a certain component. The supporting member 12 is made of at least one material, and the damper body 11 is made of at least one material. In the present embodiment, "the rigidity of the support member 12 is greater than that of the sabot body 11" means that the local deformation resistance of the support member 12 is greater than that of the sabot body 11. For example, the same voice coil 21 is placed on the support 12 and the damper body 11, the gravity of the voice coil 21 is completely borne on the support 12 and the damper body 11, and the deformation resistance of the support 12 to the gravity of the voice coil 21 is greater than that of the damper body 11 to the gravity of the voice coil 21. The strength of the deformation resistance can be represented by the degree of deformation of the force-bearing object (such as the support member 12 or the damper body 11) under the action of an external force (such as the gravity of the voice coil 21), for example, the stronger the deformation resistance, the smaller the deformation degree of the force-bearing object under the action of the external force. The concrete expressions of the material for the support member 12 and the material for the damper body 11 will be described later.

The support member 12 has a second through-hole 1211, and the specific shape of the hole cross-section of the second through-hole 1211 through the plane perpendicular to the hole axis N is not limited herein, and it is understood that the shape of the second through-hole 1211 of the support member 12 is different for different shapes of the speaker 2, for example, the hole cross-section of the second through-hole 1211 through the plane perpendicular to the hole axis N is elongated when the speaker 2 is an elongated speaker 2, and the hole cross-section of the second through-hole 1211 through the plane perpendicular to the hole axis N is circular when the speaker 2 is a circular speaker 2. It should be noted that the second through-hole 1211 should be similar in shape to the first through-hole 111.

The supporting member 12 is bonded to the wall surface of the first through hole 111, that is, the supporting member 12 is disposed corresponding to the first through hole 111, for example, a hole axis N of the second through hole 1211 of the supporting member 12 is collinear with a hole axis M of the first through hole 111 of the damper body 11. The specific connection between the support member 12 and the hole wall surface of the first through hole 111 will be described later.

The hole wall surface of the second through hole 1211 is used for connecting with the voice coil 21 of the speaker 2 when the support member 12 is used, for example, the voice coil 21 of the speaker 2 may be connected with the hole wall surface of the second through hole 1211 by glue or double-sided tape, so as to complete the assembly between the composite damper 1 and the voice coil 21 of the speaker 2.

Based on compound bullet ripples 1 in this application embodiment, through the rigidity design with support piece 12 for be greater than the rigidity of bullet ripples body 11 for this compound bullet ripples 1 adopts the structure complex of two kinds of different preparation materials to be in the same place at least, has promoted this compound structure rigidity who plays ripples 1, effectively reduces loss and deformation that this compound bullet ripples 1 vibration in-process appears because of stress is not enough and arouse, thereby effectively promotes the tone quality of speaker 2.

As shown in fig. 3 and 4, considering that the supporting member 12 is used for assisting the damper body 11 to provide support for the voice coil 21 of the speaker 2 in use, the voice coil 21 performs a motion of cutting the magnetic induction line under an external force to drive the supporting member 12 connected thereto to vibrate, and the supporting member 12 vibrates to drive the damper body 11 connected thereto to vibrate, so as to realize the overall vibration of the composite damper 1, in order to increase the vibration space of the composite damper 1, it is designed that in some embodiments, the supporting member 12 includes a connecting portion 121 and a supporting portion 122, the connecting portion 121 has a second through hole 1211, and the connecting portion 121 is used to be disposed toward the sound outlet side of the speaker 2, the supporting portion 122 is disposed around the connecting portion 121 and connected to the connecting portion 121, a side of the supporting portion 122 away from the connecting portion 121 is connected to a hole wall surface of the first through hole 111, and a portion of the supporting portion 122 is disposed outside the first through hole 111. That is, the connecting portion 121 is disposed at an interval from the damper body 11 in the direction along the hole axis N of the second through hole 1211 of the connecting portion 121, and the connecting portion 121 is connected to the hole wall surface of the first through hole 111 via the supporting portion 122. In this design, the connection portion 121 is designed, and the connection portion 121 is disposed toward the sound emitting side of the speaker 2 in use, so that the connection portion 121 is assembled between the hole wall surface of the second through hole 1211 and the voice coil 21 of the speaker 2 in use; by designing the supporting portion 122 and locating a portion of the supporting portion 122 outside the first through hole 111, on one hand, the connection between the connecting portion 121 and the hole wall surface of the first through hole 111 can be achieved, and on the other hand, the connecting portion 121 is spaced from the damper body 11 in the direction along the hole axis N of the second through hole 1211, so that the vibration space of the composite damper 1 is increased, and the ultra-thin design of the speaker 2 can be effectively achieved.

Specifically, the connecting portion 121 has a second through hole 1211, so that the connecting portion 121 is annular, and the supporting portion 122 is mainly used for connecting the connecting portion 121 and a hole wall surface of the second through hole 1211, and the specific number and shape of the supporting portion 122 are not limited herein. For example, the number of the support portions 122 may be one, and the one support portion 122 has a ring shape, and the ring-shaped support portion is disposed around the circumferential direction of the connecting portion 121; the number of the supporting portions 122 may also be multiple (i.e., two or more), and the multiple supporting portions 122 may be arc-shaped, and the multiple arc-shaped supporting portions are arranged around the circumferential direction of the connecting portion 121 at intervals, and in the circumferential direction of the connecting portion 121, the intervals between any two adjacent arc-shaped supporting portions may be equal or different.

Further, considering that the supporting portion 122 is used to connect the connecting portion 121 and the wall surface of the first through hole 111, and the connecting portion 121 is spaced from the damper body 11 in the direction along the hole axis N of the second through hole 1211 to increase the vibration space of the composite damper 1, the specific structure of the supporting portion 122 may be, but is not limited to, one or more of the following embodiments.

In one embodiment, the supporting portion 122 has a first surface 1221 disposed near the hole axis N of the second through hole 1211, and a distance between the first surface 1221 and the hole axis N of the second through hole 1211 gradually increases from a side near the connecting portion 121 to a side away from the connecting portion 121. In this design, by designing the first surface 1221 of the support portion 122 disposed near the hole axis N of the second through hole 1211 to be an inclined surface, the rigidity of the joint of the support portion 122 and the connection portion 121 can be effectively enhanced, thereby reducing the possibility of occurrence of split vibration at the joint of the support portion 122 and the connection portion 121 when the composite damper 1 vibrates. (the division vibration and the division vibration are caused by the fact that the vibration of each part of the elastic wave is not uniform when the rigidity of the elastic wave is not enough and the voice coil 21 drives the elastic wave to generate complex large-amplitude vibration.)

In one embodiment, the supporting portion 122 has a second surface 1222 disposed away from the hole axis N of the second through hole 1211, and a distance between the second surface 1222 and the hole axis N of the second through hole 1211 gradually increases from a side close to the connecting portion 121 to a side away from the connecting portion 121. In this design, by designing the second surface 1222 of the support portion 122 disposed away from the hole axis N of the second through hole 1211 as an inclined surface, the rigidity of the joint of the support portion 122 and the connection portion 121 can be effectively enhanced, thereby reducing the possibility of occurrence of split vibration at the joint of the support portion 122 and the connection portion 121 when the composite type damper 1 vibrates.

In one embodiment, the supporting portion 122 has a first surface 1221 near the hole axis N of the second through hole 1211, and a distance between the first surface 1221 and the hole axis N of the second through hole 1211 is constant from a side near the connecting portion 121 to a side away from the connecting portion 121. In this design, the first surface 1221 of the support portion 122 disposed near the hole axis N of the second through hole 1211 is designed to be a straight surface, whereby the vibration space of the composite damper 1 can be effectively increased to realize a slim design of the speaker 2.

In one embodiment, the supporting portion 122 has a second surface 1222 distant from the hole axis N of the second through hole 1211, and a distance between the second surface 1222 and the hole axis N of the second through hole 1211 is constant from a side close to the connecting portion 121 to a side distant from the connecting portion 121. In this design, by designing the second surface 1222 of the support portion 122 disposed away from the hole axis N of the second through hole 1211 to be a straight surface, the vibration space of the composite damper 1 can be effectively increased to realize a slim design of the speaker 2.

Note that, when the number of the support portions 122 is one, the support portions 122 are annular, so that the first surface 1221 of the support portion 122 disposed near the hole axis N of the second through-hole 1211 is an annular surface, and the second surface 1222 of the support portion 122 disposed away from the hole axis N of the second through-hole 1211 is an annular surface; when the number of the supporting portions 122 is plural, the supporting portions 122 may have an arc shape, so that the first surface 1221 of the supporting portion 122 disposed near the hole axis N of the second through-hole 1211 may have an arc-shaped surface, and the second surface 1222 of the supporting portion 122 disposed far from the hole axis N of the second through-hole 1211 may have an arc-shaped surface.

As shown in fig. 3 and 4, in consideration of the fact that the support 12 is used for realizing connection with the voice coil 21 of the speaker 2 on one hand and connection with the hole wall surface of the first through hole 111 of the damper body 11 on the other hand, in order to enhance the connection stability between the support 12 and the damper body 11, it is designed that in some embodiments, the support 12 further includes a rim portion 123, the rim portion 123 is disposed around the support portion 122, the rim portion 123 is connected to the side of the support portion 122 away from the connection portion 121, and the support portion 122 is connected with the hole wall surface of the first through hole 111 via the rim portion 123. In this design, by designing the edge portion 123, the support portion 122 is connected to the hole wall surface of the first through hole 111 via the edge portion 123, and the contact area between the support 12 and the hole wall surface of the first through hole 111 of the damper body 11 is increased, thereby enhancing the connection stability between the support 12 and the damper body 11.

Specifically, the edge portion 123 may be connected to the hole wall surface of the first through hole 111 of the damper body 11 by glue or double-sided tape. The number of the edge portions 123 may be one or plural, for example, when the number of the edge portions 123 is one, the one edge portion 123 has a ring shape, and the ring-shaped edge portion is provided around the circumferential direction of the support portion 122; when the number of the edge portions 123 is plural, the plural edge portions 123 may be arc-shaped, the plural arc-shaped edge portions are arranged at intervals around the circumferential direction of the supporting portion 122, and the intervals between any two adjacent arc-shaped edge portions may be equal or different along the circumferential direction of the supporting portion 122. It should be noted that one annular support portion 122 may be provided with one or more edge portions 123 in the circumferential direction, or a plurality of arc-shaped support portions 122 may be provided with one or more edge portions 123.

As shown in fig. 3 and 4, in view of the fact that the support 12 is used for realizing the connection with the voice coil 21 of the speaker 2 when in use, and in order to enhance the connection stability between the support 12 and the voice coil 21 of the speaker 2, in some embodiments, the support 12 further includes a bending portion 124, the bending portion 124 is connected to a side of the connecting portion 121 far away from the support portion 122 and is at least partially located in the second through hole 1211, the bending portion 124 has a third surface 1241 close to the hole axis N of the second through hole 1211, and the third surface 1241 is used for forming a part of the hole wall surface of the second through hole 1211, and a distance 124between the third surface 1241 and the hole axis N of the second through hole 1211 gradually decreases from the side far away from the elastic wave body 11 to the side close to the elastic wave body 11. In this design, by the design of the bent portion 124, the voice coil 21 of the speaker 2 is connected to the hole wall surface of the second through-hole 1211 via the bent portion 124, and the contact area between the voice coil 21 of the speaker 2 and the hole wall surface of the second through-hole 1211 is increased, thereby enhancing the connection stability between the support 12 and the voice coil 21 of the speaker 2; by designing the third surface 1241 of the bent portion 124, which is disposed near the hole axis N of the second through hole 1211, as an inclined surface, the rigidity of the joint of the bent portion 124 and the connecting portion 121 can be effectively enhanced, thereby reducing the possibility of occurrence of the divided vibration at the joint of the bent portion 124 and the connecting portion 121 when the composite elastic wave 1 vibrates.
