Abstract
Description
Technical Field
[0001] This application belongs to the technical field of electronic devices, and particularly relates to a camera module and an electronic device. Background Art
[0002] As users' requirements for cameras are getting higher and higher, the structure of cameras is becoming more and more complex. In related technologies, a camera includes a housing, a lens module, and an image sensor. To achieve anti-shake and focusing requirements, a movable motor mover is usually arranged in the housing to drive the movement of the lens module. However, when the camera is in a non-working state, the motor mover will move in the housing along with the shaking of the electronic device and collide with the housing, resulting in impact noise.
[0003] In related technologies, a general method to solve this problem is to set a buffer, such as Figure 1 and Figure 2 As shown, it is a periscope camera. Since the motor mover 120' of the camera 100' needs to control the movement of the lens, it cannot be completely fixed and will move up and down along the housing 110' under the action of inertia. To reduce the impact force transmitted from the motor mover 120' to the housing 110', a buffer 138' is arranged at the bottom of the housing 110'. The vibration is reduced through the buffer 138', and the collision noise is suppressed to a certain extent. However, due to the limited size inside the camera 100', the impact noise generated by the motor mover 120' hitting the buffer 138' will still be transmitted to the housing, affecting the user experience. Summary of the Invention
[0004] The purpose of the embodiments of this application is to provide a camera module and an electronic device, which can effectively solve the technical problem of large shaking noise of the camera in related technologies.
[0005] In a first aspect, the embodiments of this application provide a camera module, including:
[0006] A housing having an accommodation cavity, and a lens module is arranged in the accommodation cavity;
[0007] A motor mover movably arranged in the housing for driving the movement of the lens module;
[0008] A vibration damping assembly arranged on the housing and oppositely arranged with the motor mover. The vibration damping assembly includes a support, a buffer, and a vibration damping member. The support is arranged on the housing, the buffer is arranged on a first side of the support, and the vibration damping member is arranged on a second side of the support. The first side is the side facing the motor mover;
[0009] Wherein, the vibration damping member has a first curved surface and a second curved surface arranged opposite to each other, and both the first curved surface and the second curved surface are recessed into the interior of the vibration damping member.
[0010] Second aspect, embodiments of the present application provide an electronic device, including:
[0011] a main body; and
[0012] a camera module as provided in the embodiments of the first aspect, the camera module being provided on the main body.
[0013] In the embodiments of the present application, the camera module includes a housing, a motor mover, and a damping assembly. The housing has a receiving cavity, and a lens assembly is disposed in the receiving cavity. The motor mover is movably disposed in the receiving cavity of the housing, and the motor mover carries the lens assembly, thereby determining the movement of the lens assembly to achieve functions such as focusing or anti-shake.
[0014] The damping assembly is disposed on the housing, and the damping assembly and the motor mover are oppositely disposed, such that when the motor mover moves greatly under the action of an external force, it can hit the damping assembly, thereby reducing the vibration generated by the impact of the motor mover through the damping assembly and reducing the noise caused by the vibration.
[0015] The damping assembly includes a support member, a buffer member, and a damping member. The support member is disposed on the housing, the first side of the support member faces the motor mover, the buffer member is disposed on the first side of the support member, and the damping member is disposed on the second side of the support member. Thus, when the motor mover hits the damping assembly, it will first collide with the buffer member, and the buffer member provides a buffering effect for the motor mover to reduce the kinetic energy of the motor mover.
[0016] The damping member has a first curved surface and a second curved surface disposed opposite to each other. The damping member is recessed inward on both the first curved surface and the second curved surface, so that the thickness of the damping member between the first curved surface and the second curved surface has a variation amount. Thus, by using the variation of the thickness of the damping member, the energy generated by the vibration is consumed at the narrower part of the damping member, thereby enhancing the degree of energy consumption generated by the impact of the motor mover, reducing the noise generated by the impact of the motor mover, and improving the abnormal sound generated when the camera module shakes.

[0045] The following will describe the camera module 100 and the electronic device 200 according to the embodiments of the present application in conjunction with Figures 3 to 19 The dashed boxes in Figure 4 、 Figure 10 and Figure 15 are the installation positions of the vibration damping module 130.
[0046] As shown in Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 15 and Figure 16 The embodiments of the present application provide a camera module 100, including: a housing 110 having a receiving cavity 112, a lens module 180 disposed in the receiving cavity 112; a motor mover 120 movably disposed in the housing 110 for driving the lens module 180 to move; a vibration damping module 130 disposed on the housing 110 and opposite to the motor mover 120, the vibration damping module 130 including a support member 132, a buffer member 138, and a vibration damping member 140, the support member 132 being disposed on the housing 110, the buffer member 138 being disposed on a first side 134 of the support member 132, the vibration damping member 140 being disposed on a second side 136 of the support member 132, the first side 134 being the side facing the motor mover 120; wherein, the vibration damping member 140 has a first curved surface 142 and a second curved surface 144 disposed opposite to each other, and the vibration damping member 140 is recessed inward on both the first curved surface 142 and the second curved surface 144.
[0047] In an embodiment of the present application, the camera assembly 100 includes a housing 110, a motor mover 120, and a vibration damping assembly 130. The housing 110 has a receiving cavity 112, and a lens assembly 180 is disposed in the receiving cavity 112. The motor mover 120 is movably disposed in the receiving cavity 112 of the housing 110, and the motor mover 120 carries the lens assembly 180, thereby determining the movement of the lens assembly 180 to achieve functions such as focusing or anti-shake.
[0048] The vibration damping assembly 130 is disposed on the housing 110, and the vibration damping assembly 130 and the motor mover 120 are oppositely disposed, such that when the motor mover 120 moves greatly under the action of an external force, it can hit the vibration damping assembly 130, thereby reducing the vibration generated by the impact of the motor mover 120 through the vibration damping assembly 130 and reducing the noise caused by the vibration.
[0049] The vibration damping assembly 130 includes a support member 132, a buffer member 138, and a vibration damping member 140. The support member 132 is disposed on the housing 110, a first side 134 of the support member 132 faces the motor mover 120, the buffer member 138 is disposed on the first side 134 of the support member 132, and the vibration damping member 140 is disposed on a second side 136 of the support member 132. Thus, when the motor mover 120 hits the vibration damping assembly 130, it will first collide with the buffer member 138, and the buffer member 138 provides a buffering effect for the motor mover 120 to reduce the kinetic energy of the motor mover 120.
[0050] The vibration damping member 140 has a first curved surface 142 and a second curved surface 144 that are oppositely disposed. The vibration damping member 140 is recessed inwardly on both the first curved surface 142 and the second curved surface 144, so that the thickness of the vibration damping member 140 between the first curved surface 142 and the second curved surface 144 has a variation. Thus, by using the variation in the thickness of the vibration damping member 140, the energy generated by the vibration is consumed at the narrower part of the vibration damping member 140, thereby enhancing the degree of energy consumption generated by the impact of the motor mover 120, reducing the noise generated by the impact of the motor mover 120, and improving the abnormal noise generated when the camera assembly 100 shakes.
[0051] Optionally, the number of the vibration damping members 140 can be one, two, or more, etc., and multiple vibration damping members 140 can be arranged in an array. Optionally, the camera assembly is a periscope camera.
[0052] Among them, sound is a kind of wave, and when reflected on the camera assembly 100, it can be regarded as a kind of vibration energy. When the motor mover 120 collides with the vibration damping assembly 130, sound waves are generated, and the sound waves are transmitted to the vibration damping member 140 through the buffer member 138 and the support member 132, and the vibration damping member 140 absorbs the sound waves, thereby reducing the sound emitted to the outside of the housing 110.
[0053] As described above, the present application adds a vibration damping member 140 to the sound wave propagation path, thereby enhancing the ability of the vibration damping assembly 130 to vibrate the energy of the sound wave and significantly improving the vibration damping and noise reduction effect.
[0054] The second side 136 of the support member 132 may be the circumferential side of the support member 132 or the side of the support member 132 facing away from the motor mover 120.
[0055] As Figure 7 、 Figure 8 、 Figure 13 and Figure 14 As shown, as a possible implementation manner, the thickness change of the portion of the vibration damping member 140 between the first curved surface 142 and the second curved surface 144 follows a power-law distribution.
[0056] Optionally, the thickness change of the portion of the vibration damping member 140 between the first curved surface 142 and the second curved surface 144 follows a power-law distribution, so as to gradually decrease during the transmission of the sound wave and even decrease to zero in an ideal situation, thereby enhancing the weakening effect on the sound wave and improving the noise reduction effect.
[0057] As described above, the vibration damping member 140 can generally form a structure of an acoustic black hole. An acoustic black hole utilizes the gradient change of the geometric parameters or material characteristic parameters of a thin-walled structure, so that the wave propagation speed in the structure gradually decreases and even decreases to zero in an ideal situation, and then the wave aggregation effect is generated at the end to form a high energy density region. Optionally, as Figure 9 shown, the thickness change law of the structure of an ideal acoustic black hole follows a power-law distribution h(x) = εx m where h(x) represents the thickness, ε represents the profile slope, m represents the black hole order, x represents the x-axis, and the thickness of the structure of the acoustic black hole decreases along the direction in which the x-axis decreases.
[0058] The present application improves the noise reduction effect by adding the vibration damping member 140, so that the vibration propagation speed in the structure gradually decreases and even decreases to zero in an ideal situation. Moreover, the present application utilizes the original spatial structure of the camera assembly 100 without adding additional use space.
[0059] In the present application, the sound wave transmission mode is as follows: when the motor mover 120 moves due to inertia, it impacts on the vibration damping assembly 130. After the vibration is buffered by the buffer member 138, most of the vibration is still transmitted to the support member 132 and then absorbed by the vibration damping member 140, so that the vibration propagation speed gradually decreases, and the vibration energy generated by the collision of the motor mover 120 can be effectively absorbed, achieving the effect of reducing the collision noise.
[0060] As Figure 7As shown, as a possible implementation, the first end 146 of the vibration damping member 140 is connected to the support member 132, the second end 148 of the vibration damping member 140 is away from the support member 132, and both sides of the first end 146 and the second end 148 are transitioned through the first curved surface 142 and the second curved surface 144 respectively.
[0061] Optionally, the first end 146 of the vibration damping member 140 is connected to the support member 132, the second end 148 of the vibration damping member 140 is away from the support member 132, and both sides of the first end 146 and the second end 148 are transitioned through the first curved surface 142 and the second curved surface 144 respectively, so that the vibration damping member 140 forms a wedge-shaped structure.
[0062] Wherein, the thickness of the first end 146 is greater than the thickness of the second end 148, and the second end 148 is the region with the thinnest thickness of the vibration damping member 140, such as Figure 7 and Figure 8 As shown, the wedge-shaped vibration damping member 140 forms an acoustic black hole, the second end 148 of the vibration damping member 140 faces away from the support member 132, and the vibration transmission direction is as shown in Figure 8 As shown, and then the sound wave is transmitted from the first end 146 with a larger width of the vibration damping member 140 to the second end 148 of the vibration damping member 140, so as to achieve an energy absorption effect at the second end 148. The structure of the vibration damping member 140 is simple, easy to manufacture, and has high reliability.
[0063] Wherein, the vibration damping member 140 can be arranged on the side of the support member 132 away from the motor mover 120. The vibration damping member 140 is a wedge-shaped structure whose cross-sectional thickness satisfies or approximately satisfies the power-law distribution. A damping member 150 is laid on the second section of the vibration damping member 140 to attenuate and dissipate the vibration energy transmitted due to the collision of the motor mover 120. As shown in Figure 7 As shown, the thickness W2 of the damping member 150 is several times the thickness W1 of the second end 148 of the vibration damping member 140, and this multiple can be 2 times or 4 times, etc. through specific structural design. Wherein, the thickness at the position where the vibration damping member 140 is connected to the support member 132 is not limited, and the height of the vibration damping member 140 is not limited either, as long as it satisfies the power-law distribution law of the thickness change of the acoustic black hole. The distribution quantity, position and range of the vibration damping member 140 on the support member 132 are not limited.
[0064] According to the principle of the acoustic black hole, when the vibration is transmitted to the support member 132 and then to the vibration damping member 140, it is transmitted from the place with the largest thickness to the place with the smallest thickness at the end, and the propagation speed gradually decreases. Finally, an aggregation effect is generated at the end, and the damping member 150 at the end can dissipate the transmitted energy, so that the vibration on the support member 132 is greatly reduced and then transmitted to the housing 110, effectively reducing the collision noise. As shown in Figure 7 As shown, along the AB direction, the dimension of the vibration damping member 140 in the CD direction conforms to the power-law distribution.
[0065] As Figure 13 and Figure 14 shown, as a possible implementation, one end of the vibration damping member 140 is connected to the support member 132, the first curved surface 142 faces the support member 132, the second curved surface 144 faces away from the support member 132, the distance between the middle positions of the first curved surface 142 and the second curved surface 144 is the first dimension D1, the distance between the edge positions of the first curved surface 142 and the second curved surface 144 is the second dimension D2, and the first dimension D1 is less than the second dimension D2.
[0066] Optionally, one end of the vibration damping member 140 is connected to the support member 132, the first curved surface 142 and the second curved surface 144 are distributed on the side of the vibration damping member 140 facing the support member 132 and the side facing away from the support member 132, the distance between the middle positions of the first curved surface 142 and the second curved surface 144 is the first dimension D1, the distance between the edge positions of the first curved surface 142 and the second curved surface 144 is the second dimension D2, and the first dimension D1 is less than the second dimension D2, so that the thickness of the vibration damping member 140 between the first curved surface 142 and the second curved surface 144 conforms to the power-law distribution.
[0067] That is, the side of the vibration damping member 140 facing the support member 132 has the first curved surface 142, the side of the vibration damping member 140 facing away from the support member 132 has the second curved surface 144. The settings of the first curved surface 142 and the second curved surface 144 cause a narrower part to appear in the middle position of the vibration damping member 140, thus forming an acoustic black hole to absorb sound waves. The edge of the first curved surface 142 has a mounting surface, and the mounting surface is connected to the support member 132, so as to facilitate the transmission of sound waves on the support member 132 to the vibration damping member 140.
[0068] Among them, the vibration damping member 140 is laid on the side of the support member 132 facing away from the motor mover 120, and the structure of the vibration damping member 140 is similar to the structural dimensions of the beam. As Figure 8 and Figure 9 shown, the side of the vibration damping member 140 facing the support member 132 has the first curved surface 142, the side of the vibration damping member 140 facing away from the support member 132 has the second curved surface 144, making the vibration damping member 140 a beam with a thickness distribution satisfying the power-law distribution of the acoustic black hole. And a damping member 150 is arranged at the middle position of the vibration damping member 140. Among them, the maximum thickness of the vibration damping member 140 is distributed at both ends, and the minimum thickness is distributed in the middle region. The damping member 150 is laid in the middle region of the vibration damping member 140. To ensure sufficient strength of the vibration damping member 140, the maximum thickness of the vibration damping member 140 should be at a certain distance from the edge of the vibration damping member 140 to facilitate the formation of the mounting surface.
[0069] Optionally, the size of the mounting surface is L to ensure the strength of the vibration damping member 140 and the reliability of vibration absorption of the vibration damping member 140.
[0070] According to the acoustic black hole principle, when vibration is transmitted to the support member 132 and then to the vibration damping member 140, it is transmitted from the places with the largest thickness at both ends to the place with the smallest thickness in the middle, and finally an aggregation effect is generated in the middle. The damping member 150 provided in the middle can dissipate the transmitted energy, thereby greatly reducing the vibration on the support member 132 and then transmitting it to the housing 110, effectively reducing the collision noise.
[0071] Among them, the vibration damping member 140 can be provided on the support member 132 of the main vibration transmission path of the camera module 100. In practical applications, according to the internal space layout of the camera module 100, the vibration damping member 140 can be provided in the area where the housing 110 vibrates more, and the effect of vibration absorption and noise reduction can also be achieved.
[0072] Compared with the vibration damping structure in the related art, without additional use space, the vibration amplitude transmitted to the housing 110 is greatly reduced by the added vibration damping member 140 in this application. The vibration damping member 140 provided with reference to the acoustic black hole principle not only greatly improves the vibration absorption effect, but also has a particularly prominent vibration reduction effect on the vibration in the medium and high frequency bands, and can meet various vibration damping requirements occurring in practice.
[0073] As Figure 13 shown, along the AB direction, at least part of the vibration damping member 140 conforms to the power-law distribution in the CD direction.
[0074] As Figure 6 、 Figure 7 、 Figure 8 、 Figure 12 、 Figure 13 and Figure 14 shown, as a possible implementation manner, it further includes: a damping member 150, provided on the surface of the vibration damping member 140, covering at least the thinnest region between the first curved surface 142 and the second curved surface 144.
[0075] Optionally, the camera module 100 further includes a damping member 150 provided on the vibration damping member 140. The damping member 150 is attached to the surface of the vibration damping member 140, and the damping member 150 covers at least the thinnest region between the first curved surface 142 and the second curved surface 144, so as to further absorb sound waves by using the damping member 150 and improve the effect of reducing the shaking abnormal sound of the camera module 100.
[0076] Among them, the material of the damping member 150 can be sponge, foam, rubber, silica gel or polymer material, etc.
[0077] The thinnest region between the first curved surface 142 and the second curved surface 144 is the energy aggregation region of the vibration damping member 140. By covering the damping member 150 at the tip or other narrower regions of the vibration damping member 140, the effects of energy absorption and vibration and noise reduction are achieved.
[0078] like Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, as a possible implementation, it also includes: an elastic vibration absorbing component 160, which is connected to the support member 132, and the elastic vibration absorbing component 160 is located on the side of the support member 132 away from the motor mover 120; wherein the vibration damping member 140 is arranged on the peripheral side of the support member 132, and the shell 110 has a first opening 114, and the support member 132 extends from the first opening 114 into the accommodating cavity 112.
[0079] Optionally, the camera assembly 100 also includes an elastic vibration absorbing assembly 160, which is connected to the side of the support member 132 facing away from the motor mover 120, and the second side 136 is located on the peripheral side of the support member 132, that is, the vibration damping member 140 is arranged on the peripheral side of the support member 132, and the shell 110 has a first opening 114, thereby providing an installation space for the vibration damping member 140, and the support member 132 extends from the first opening 114 into the accommodating cavity 112. Through the elastic deformation of the elastic vibration absorbing assembly 160, the absorption capacity of sound waves is further improved, and the noise reduction effect is further improved.
[0080] As a possible implementation, the elastic vibration absorbing component 160 includes: a first elastic member 162, one end of which is connected to the support member 132, and the other end is suspended in the air; or the elastic vibration absorbing component 160 includes: both ends of the first elastic member 162 are connected to the support member 132, and the middle part of the first elastic member 162 is suspended in the air; and a mass member 164 is arranged on the first elastic member 162.
[0081] Alternatively, if Figure 17 As shown, the elastic vibration absorbing assembly 160 includes a first elastic member 162 and a mass member 164. The mass member 164 is arranged on the first elastic member 162. When the first elastic member 162 receives sound waves, it shakes and cooperates with the mass member 164 to achieve the effect of absorbing the sound waves. Such a setting has a simple structure and high reliability.
[0082] The first elastic member 162 may be connected to the support member 132 at one end and suspended at the other end, and the mass member 164 is disposed on the first elastic member 162. When the first elastic member 162 receives sound waves, the first elastic member 162 shakes to a certain extent under the inertia of the mass member 164, its own elasticity and the sound waves, thereby achieving the effect of absorbing the sound waves. The first elastic member 162 may be a coil spring.
[0083] or Figure 18As shown, the first elastic member 162 may be connected to the support member 132 at both ends, with the middle part suspended, and the mass member 164 is disposed on the suspended part of the first elastic member 162, so that when the first elastic member 162 receives sound waves, the first elastic member 162 shakes to a certain extent under the inertia of the mass member 164, its own elasticity and the sound waves, thereby achieving the effect of absorbing the sound waves. The first elastic member 162 may be a plate spring.
[0084] The first elastic member 162 may also be replaced by a spring, a spring sheet or other types of elastic units.
[0085] like Figure 17 and Figure 18 As shown, as a possible implementation, the number of elastic vibration absorbing components 160 is at least two, and the stiffness of the first elastic member 162 and the mass of the mass member 164 in the at least two elastic vibration absorbing components 160 have at least two combinations.
[0086] Optionally, the number of elastic vibration absorbing components 160 is at least two, and at least two elastic vibration absorbing components 160 have at least two vibration absorbing frequency bands, thereby improving the frequency band of sound wave absorption by the elastic vibration absorbing components 160 and improving the effect of reducing shaking and abnormal noise of the camera assembly 100.
[0087] The absorption frequency band of the elastic vibration absorbing component 160 to sound waves can be changed by changing the stiffness of the first elastic member 162 and the mass of the mass member 164 .
[0088] The elastic vibration absorbing component 160 can cope with various vibration reduction needs that occur in practice, especially the improvement of vibrations in the medium and high frequency bands. In addition, a multi-stage vibration reduction structure is set up. By adding vibration reduction parts 140 and other vibration reduction structures, the multi-band coverage of sound wave absorption is improved, thereby further improving the vibration reduction effect.
[0089] like Figure 16 As shown, as a possible implementation, the housing 110 has a support portion 118 , which is located on the side of the support member 132 away from the motor mover 120 , and the camera assembly 100 also includes a second elastic member 170 , which is located between the support portion 118 and the support member 132 .
[0090] Optionally, the housing 110 has a support portion 118 , which is disposed on a side of the support member 132 away from the motor mover 120 , and a second elastic member 170 is disposed between the support member 132 and the support portion 118 , so that the support member 132 is supported by the second elastic member 170 .
[0091] Among them, the second elastic member 170 can be arranged at the edge of the support member 132 to provide installation space for the vibration damping member 140 and the elastic vibration absorbing assembly 160. The support portion 118 has a groove, and the second elastic member 170 is arranged in the groove to improve the stability of the second elastic member 170.
[0092] The second elastic member 170 can be made of rubber or silicone material.
[0093] That is, the second elastic member 170 is disposed on the side of the support member 132 facing away from the motor mover 120 , and the second elastic member 170 cooperates with the groove on the housing 110 to further provide buffering.
[0094] like Figure 16 , Figure 17 and Figure 18 As shown, the present application further adds an elastic vibration absorbing component 160 on the basis of adding a vibration damping component 140. The elastic vibration absorbing component 160 includes a first elastic component 162 and a mass component 164. The vibration damping component 140 can be arranged on the peripheral side of the support member 132, and the first elastic component 162, the mass component 164 and the second elastic component 170 are also arranged on the side of the support member 132 away from the motor mover 120, wherein the first elastic component 162 and the mass component 164 are connected, and the two cooperate to form a dynamic vibration absorber. In addition, the vibration absorbing frequency band range of the elastic vibration absorbing component 160 can be adjusted by changing the stiffness of the first elastic component 162 and the mass of the mass component 164. A plurality of elastic vibration absorbing components 160 can be arranged on the support member 132, and the stiffness of the first elastic component 162 and the mass of the mass component 164 in each elastic vibration absorbing component 160 can be a plurality of combinations to achieve a wide-band vibration damping effect of the elastic vibration absorbing component 160.
[0095] The vibration reduction process of the camera assembly 100 provided in the present application is as follows: when the motor mover 120 collides with the buffer 138, the vibration energy is first transmitted to the vibration reduction member 140 through the support member 132, and then transmitted to the housing 110 through the vibration reduction effect of the elastic vibration absorption member 160, and finally further buffered by the second elastic member 170. After multiple levels of vibration reduction, the vibration is greatly attenuated, and the collision noise can be significantly improved. At the same time, the vibration reduction frequency band range can be adjusted through the elastic vibration absorption member 160, further improving the frequency band range covered by the vibration reduction.
[0096] Moreover, other vibration absorbing parts may be further added as required to maximize the vibration reduction and noise reduction effect of the camera assembly 100.
[0097] like Figure 16 As shown, as a possible implementation, the housing 110 has a second opening 116 , the buffer member 138 extends from the second opening 116 into the accommodating cavity 112 , and the edge of the second opening 116 is blocked by the edge of the support member 132 .
[0098] Optionally, the housing 110 further has a second opening 116. The buffer member 138 extends into the accommodation cavity 112 through the second opening 116, and the edge of the second opening 116 provides a limit for the support member 132 to prevent the support member 132 from entering the accommodation cavity 112 through the second opening 116, thereby restricting the vibration damping assembly 130 to one side of the motor mover 120, thus ensuring the reliability of the vibration damping assembly 130.
[0099] Wherein, the vibration damping member 140 is disposed on the side of the support member 132 away from the motor mover 120, or, when the vibration damping member 140 is disposed on the periphery of the support member 132, the housing 110 has a first opening 114, and the vibration damping member 140 extends into the first opening 114.
[0100] The vibration damping assembly 130 of the camera module 100 provided by the present application, compared with the vibration damping structure in the related art, without additionally increasing the usage space, adds a vibration damping member 140 to greatly reduce the vibration amplitude transmitted to the housing 110. The vibration damping member 140 provided by referring to the acoustic black hole principle not only greatly improves the vibration absorption effect, but also has a particularly prominent vibration reduction effect on the vibration in the medium and high frequency bands. On this basis, an elastic vibration absorption assembly 160 can be further provided to meet various vibration damping requirements occurring in practice, improve the problem of shaking and abnormal noise of the camera module 100, and enhance the user experience.
