Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0036] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the structure of a chip multilayer capacitor in the related art; Figure 2Schematic diagram of vibration of chip multilayer capacitor in related art. The capacitor 110 generally includes a dielectric 111, an inner electrode 112 and an outer electrode 113. The capacitor 110 is made of dielectric diaphragms with inner electrodes 112 printed on them, stacked in an offset manner, and sintered at high temperature once to form a chip in which the inner electrode 112 is wrapped by the dielectric 111, and then the outer electrodes 113 are sealed at both ends of the chip. When the capacitor 110 is powered on, the voltage will generate an electric field on the inner electrode 112 (such as Figure 2 and the electric field acts on the inner electrode 112 to form a mechanical force (such as Figure 2 F11, F12, F13, F21, F22 and F23 in FIG. 1 ), that is, the conversion between electrical energy and mechanical energy occurs, which is also called the inverse piezoelectric effect. The mechanical force formed by the electric field on the inner electrode 112 causes the inner electrode 112 to expand and contract slightly (such as Figure 2 d), although the expansion and contraction of the inner electrode 112 is small and changes at the nanometer level, the inner electrode 112 will expand and contract repeatedly during the power-on process, thereby accelerating the vibration frequency of the capacitor 110, so that the capacitor 110 emits a whistling sound. It should be noted that the expansion and contraction of the inner electrode 112 is mainly in the stacking direction of the inner electrode 112, that is, the vibration of the capacitor 110 in the stacking direction of the inner electrode 112 is the main reason for the capacitor 110 to produce a whistling sound.
[0038] The present application provides a capacitor assembly 100. Figure 3 , Figure 3 A schematic diagram of the structure of a capacitor assembly provided in the first embodiment of the present application. The capacitor assembly 100 includes a capacitor 110, a first pin 120, a second pin 130 and a damper 140. The second pin 130 and the first pin 120 are respectively connected to two opposite ends of the capacitor 110, and the second pin 130, the first pin 120 and the capacitor 110 form a housing space 150. The damper 140 is disposed in the housing space 150, and the damper 140 includes a first support member 141, the first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence, the first free end 1411 is used to support the capacitor, the second free end 1413 is away from the capacitor compared to the first free end 1411, and the first free end 1411 can move relative to the second free end 1413.
[0039] The capacitor 110 provided in the present application is a chip-type multilayer ceramic capacitor (Multi-layer Ceramic Capacitors, MLCC). The capacitor 110 is a static charge storage medium. The capacitor 110 has a wide range of uses and is an indispensable electronic component in the fields of electronics and electricity. The capacitor 110 is mainly used in circuits such as power filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and DC isolation.
[0040] The first pin 120 and the second pin 130 are respectively connected to two opposite ends of the capacitor 110. Specifically, the first pin 120 and the second pin 130 are connected to the capacitor 110 through the external electrodes 113 connected to the two opposite ends of the capacitor 110, and the first pin 120 and the second pin 130 are used to support the capacitor 110. The connection between the first pin 120 and the second pin 130 and the capacitor 110 is an electrical connection, that is, the first pin 120 and the second pin 130 are conductive materials, such as copper, iron or aluminum.
[0041] The vibration damper 140 is disposed in the accommodation space 150, and the vibration damper 140 is used to support the capacitor 110. The vibration damper 140 is elastic. In one embodiment, the vibration damper 140 is made of an elastic material, so that the vibration damper 140 can move with the vibration of the capacitor 110. For example, the vibration damper 140 can be rubber, latex or elastic fiber. In another embodiment, the vibration damper 140 is made of a material with relatively high hardness, and the material of the vibration damper 140 itself is not very elastic, or even has no elasticity. The vibration damper 140 has elasticity due to its own shape, so that the vibration damper 140 can move with the vibration of the capacitor 110. For example, the vibration damper 140 can be iron, steel or hard plastic. The vibration damper 140 can be "C" shaped, "Z" shaped or "O" shaped. In one embodiment, the vibration absorber 140 is non-conductive, which can prevent the vibration absorber 140 from affecting the magnetic circuit or electrical performance of the capacitor 110, and is conducive to the vibration absorber 140 to reduce the vibration of the capacitor 110, thereby suppressing or even eliminating the howling.
[0042] In this embodiment (see Figure 3), the shock absorber 140 includes a first support member 141. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 is away from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. The first connecting portion 1412 can be, but is not limited to, connecting the first free end 1411 and the second free end 1413 through a bending shape or an arc shape, as long as the first free end 1411 can move relative to the second free end 1413. In the capacitor assembly 100 provided in the embodiment of the present application, the first free end 1411 supports the capacitor 110, and the first free end 1411 can move relative to the second free end 1413, without causing the first free end 1411 to be disconnected from the first connecting portion 1412, but rather is achieved by elastic deformation generated by the elasticity of the first support member 141 itself. The first free end 1411 can move closer to the second free end 1413, or move away from the second free end 1413.
[0043] The capacitor assembly 100 provided in the present application includes a capacitor 110, a first pin 120, a second pin 130 and a vibration damper 140, wherein the vibration damper 140 is disposed in a housing space 150 formed by the capacitor 110, the first pin 120 and the second pin 130, and the vibration damper 140 is used to dampen the vibration of the capacitor 110. Since the vibration damper supports the capacitor, the vibration amplitude and frequency of the capacitor are reduced. In addition, when the capacitor 110 is working, the vibration of the capacitor 110 drives the vibration damper 140 to move, so that the vibration damper 140 will vibrate with the capacitor 110, thereby transferring the deformation generated by the vibration of the capacitor 110 to the air in the housing space 150, that is, the kinetic energy of the vibration of the vibration damper 140 is converted into heat energy and dissipated into the air through the friction between the vibration damper 140 and the air. In addition, the air in the accommodating space 150 is repeatedly compressed and released as the vibration of the vibration absorber 140 occurs. During this process, friction occurs between the air and the vibration absorber 140 and between the air molecules themselves, which forms a damping force on the vibration of the vibration absorber 140, suppressing the amplitude and frequency of the vibration of the vibration absorber 140. Therefore, the capacitor assembly 100 provided in the present application can reduce the vibration frequency of the capacitor 110 through the vibration absorber 140 to suppress or even eliminate the howling generated during the operation of the capacitor 110. When the capacitor assembly 100 is applied to a display device, the quality of the display device is higher.
[0044] Please refer to Figure 4 , Figure 4 A schematic diagram of the structure of a capacitor assembly provided in the second embodiment of the present application. In this embodiment, the capacitor assembly 100 includes a capacitor 110, a first pin 120, a second pin 130 and a damper 140. The second pin 130 and the first pin 120 are respectively connected to two opposite ends of the capacitor 110, and the second pin 130, the first pin 120 and the capacitor 110 form a housing space 150. The damper 140 is arranged in the housing space 150 and is used to dampen the vibration of the capacitor 110. Among them, the damper 140 includes a first support member 141 and a second support member 142. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 is away from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. When the vibration absorber 140 includes a second support member 142, the second support member 142 has a third free end 1421, a second connecting portion 1422, and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411 and is used to support the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is away from the capacitor 110 compared to the third free end 1421. The third free end 1421 can move relative to the fourth free end 1423.
[0045] In this embodiment (see Figure 4 ), the vibration absorber 140 includes a first support member 141 and a second support member 142. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 is away from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. The second support member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411 and is used to support the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is away from the capacitor 110 compared to the third free end 1421. The third free end 1421 can move relative to the fourth free end 1423 .
[0046] In this embodiment, the first connection portion 1412 may be, but is not limited to, connected to the first free end 1411 and the second free end 1413 by a bending shape or an arc shape, as long as the first free end 1411 can move relative to the second free end 1413. In the capacitor assembly 100 provided in the embodiment of the present application, the first free end 1411 supports the capacitor 110, and the first free end 1411 can move relative to the second free end 1413, and the first free end 1411 does not break away from the connection with the first connection portion 1412, but is realized by elastic deformation generated by the elasticity of the first support member 141 itself. The first free end 1411 can move closer to the second free end 1413 or move away from the second free end 1413. The second connection portion 1422 may be, but is not limited to, connected to the third free end 1421 and the fourth free end 1423 by a bending shape or an arc shape, as long as the third free end 1421 can move relative to the fourth free end 1423. The third free end 1421 moves relative to the fourth free end 1423, but does not cause the third free end 1421 to be disconnected from the second connection portion 1422, but is achieved by elastic deformation due to the elasticity of the second support member 142. The third free end 1421 can move closer to the fourth free end 1423 or move away from the fourth free end 1423.
[0047] In this embodiment, the third free end 1421 is used to support the capacitor 110, and the third free end 1421 and the capacitor 110 move together, that is, the third free end 1421 and the capacitor 110 can move together relative to the fourth free end 1423. Since the third free end 1421 and the first free end 1411 are spaced apart, and the third free end 1421 and the first free end 1411 are both used to support the capacitor 110, the third free end 1421 and the first free end 1411 jointly support the capacitor 110. At the same time, the second connecting portion 1422 is connected to the first connecting portion 1412, so that the second supporting member 142 and the first supporting member 141 can vibrate with the capacitor 110 at the same time, that is, when the third free end 1421 moves relative to the fourth free end 1423, the first free end 1411 also moves relative to the second free end 1413. The second support member 142 and the first support member 141 jointly support the capacitor 110 and vibrate along with the vibration of the capacitor 110 , so that the capacitor 110 is more stable during the vibration process.
[0048] Please refer to Figure 5 , Figure 5 for Figure 3 Schematic diagram of the elastic deformation of the shock absorber provided in the implementation manner. The first free end 1411 moves relative to the second free end 1413, and the stroke L1 of the first free end 1411 relative to the second free end 1413 satisfies: 1mm≤L1≤1.5mm. For example, L1=1mm, or L1=1.1mm, or L1=1.2mm, or L1=1.3mm, or L1=1.4mm, or L1=1.5mm. The stroke L1 of the first free end 1411 relative to the second free end 1413 is introduced below. When the first support member 141 is in a natural state (state a), the distance between the first free end 1411 and the second free end 1413 is L 11 When the first support member 141 is in the maximum compression state (state b), the distance between the first free end 1411 and the second free end 1413 is L 12 When the first support member 141 is in the maximum tension state (state c), the distance between the first free end 1411 and the second free end 1413 is L 13 Then, the maximum travel of the first free end 1411 moving toward the second free end 1413 is: L1 = L 11 -L 12 The maximum travel of the first free end 1411 moving in a direction away from the second free end 1413 is L1 = L 13 -L 11. In the present embodiment, both the maximum stroke L1 of the first free end 1411 moving toward the direction close to the second free end 1413 and the maximum stroke L1 of the first free end 1411 moving away from the second free end 1413 satisfy 1mm≤L1≤1.5mm. It should be noted that the maximum stroke of the first free end 1411 moving toward the direction close to the second free end 1413 may be equal to or unequal to the maximum stroke of the first free end 1411 moving away from the second free end 1413. If the stroke L1 of the first free end 1411 moving relative to the second free end 1413 is greater than 1.5mm, the vibration amplitude of the capacitor 110 will be too large, which may cause the first free end 1411 to contact or even collide with the second free end 1413, affecting the vibration reduction effect of the first support member 141. If the stroke L1 of the first free end 1411 relative to the second free end 1413 is less than 1 mm, the first support member 141 will not be able to provide a sufficiently strong damping force during the vibration of the capacitor 110, which will affect the vibration reduction effect of the first support member 141. By limiting the stroke L1 of the first free end 1411 relative to the second free end 1413, the first support member 141 can provide a sufficiently strong damping force during the vibration of the capacitor 110, thereby reducing the vibration amplitude and frequency of the capacitor 110, and suppressing or even eliminating the howling caused by the vibration of the capacitor 110.
[0049] Please refer to Figure 6 , Figure 6 for Figure 4 Schematic diagram of elastic deformation of shock absorber provided in the embodiment. The first free end 1411 moves relative to the second free end 1413, and the travel L1 of the first free end 1411 relative to the second free end 1413 satisfies: 1mm≤L1≤1.5mm. The travel L2 of the third free end 1421 relative to the fourth free end 1423 satisfies: 1mm≤L2≤1.5mm.
[0050] For example, L1=1 mm, or L1=1.1 mm, or L1=1.2 mm, or L1=1.3 mm, or L1=1.4 mm, or L1=1.5 mm. The following describes the travel L1 of the first free end 1411 relative to the second free end 1413. When the first support member 141 is in the natural state (state A), the distance between the first free end 1411 and the second free end 1413 is L 11 When the first support member 141 is in the maximum compression state (state B), the distance between the first free end 1411 and the second free end 1413 is L 12When the first support member 141 is in the maximum tension state (state C), the distance between the first free end 1411 and the second free end 1413 is L 13 Then, the maximum travel L1 of the first free end 1411 moving toward the second free end 1413 is: L1 = L 11 -L 12 The maximum travel of the first free end 1411 moving in a direction away from the second free end 1413 is: L1 = L 13 -L 11 . In the present embodiment, both the maximum stroke L1 of the first free end 1411 moving toward the direction close to the second free end 1413 and the maximum stroke L1 of the first free end 1411 moving away from the second free end 1413 satisfy 1mm≤L1≤1.5mm. It should be noted that the maximum stroke of the first free end 1411 moving toward the direction close to the second free end 1413 may be equal to or unequal to the maximum stroke of the first free end 1411 moving away from the second free end 1413. If the stroke L1 of the first free end 1411 moving relative to the second free end 1413 is greater than 1.5mm, the vibration amplitude of the capacitor 110 will be too large, which may cause the first free end 1411 to contact or even collide with the second free end 1413, affecting the vibration reduction effect of the first support member 141. If the stroke L1 of the first free end 1411 relative to the second free end 1413 is less than 1 mm, the first support member 141 will not be able to provide a sufficiently strong damping force during the vibration of the capacitor 110, which will affect the vibration reduction effect of the first support member 141. By limiting the stroke L1 of the first free end 1411 relative to the second free end 1413, the first support member 141 can provide a sufficiently strong damping force during the vibration of the capacitor 110, thereby reducing the vibration amplitude and frequency of the capacitor 110, and suppressing or even eliminating the howling caused by the vibration of the capacitor 110.
[0051] For example, L2=1mm, or L2=1.1mm, or L2=1.2mm, or L2=1.3mm, or L2=1.4mm, or L2=1.5mm. The following is an introduction to the travel L2 of the third free end 1421 relative to the fourth free end 1423. When the second support member 142 is in the natural state (state A), the distance between the third free end 1421 and the fourth free end 1423 is L 21 When the second support member 142 is in the maximum compression state (state B), the distance between the third free end 1421 and the fourth free end 1423 is L 22When the second support member 142 is in the maximum tension state (state C), the distance between the third free end 1421 and the fourth free end 1423 is L 23 Then, the maximum travel L2 of the third free end 1421 moving toward the fourth free end 1423 is: L2 = L 21 -L 22 The maximum travel L2 of the third free end 1421 moving in a direction away from the fourth free end 1423 is: L2 = L 23 -L 21 . In this embodiment, both the maximum stroke L2 of the third free end 1421 moving toward the direction close to the fourth free end 1423 and the maximum stroke L2 of the third free end 1421 moving away from the fourth free end 1423 satisfy 1mm≤L2≤1.5mm. It should be noted that the maximum stroke of the third free end 1421 moving toward the direction close to the fourth free end 1423 may be equal to or unequal to the maximum stroke of the third free end 1421 moving away from the fourth free end 1423. If the stroke L2 of the third free end 1421 moving relative to the fourth free end 1423 is greater than 1.5mm, the vibration amplitude of the capacitor 110 will be too large, which may cause the third free end 1421 to contact or even collide with the fourth free end 1423, affecting the vibration reduction effect of the second support member 142. If the stroke L2 of the third free end 1421 relative to the fourth free end 1423 is less than 1 mm, the second support member 142 will not be able to provide a sufficiently strong damping force during the vibration of the capacitor 110, which will affect the vibration reduction effect of the second support member 142. By limiting the stroke L2 of the third free end 1421 relative to the fourth free end 1423, the second support member 142 can provide a sufficiently strong damping force during the vibration of the capacitor 110, thereby reducing the vibration amplitude and frequency of the capacitor 110, and suppressing or even eliminating the howling caused by the vibration of the capacitor 110.
[0052] Please refer to Figure 4 and Figure 7 , Figure 7 for Figure 4A distribution diagram of a vibration damper in a capacitor assembly provided in an embodiment. In this embodiment, the vibration damper 140 includes a first support member 141, or the vibration damper 140 includes a first support member 141 and a second support member 142. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 deviates from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. When the vibration damper 140 includes a second support member 142, the second support member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411 and is used to support the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is away from the capacitor 110 compared to the third free end 1421. The third free end 1421 can move relative to the fourth free end 1423. In addition, in this embodiment, the number of the dampers 140 is two or more, and the dampers 140 are evenly spaced in the extending direction of the first pin 120. It should be noted that the schematic diagram of this embodiment is based on the number of the dampers 140 being two or more and being combined with Figure 4 The implementation method is illustrated in FIG. 1 , and it can be understood that Figure 7 The structural schematic diagram of the capacitor assembly 100 described in the figure does not limit the capacitor assembly 100 provided in the present application.
[0053] In this embodiment, the extending direction of the first pin 120 refers to the direction in which the damper 140 is not wrapped by the capacitor 110, the first pin 120 and the second pin 130, that is, Figure 7 The direction indicated by the middle indicator line D or the opposite direction.
[0054] In this embodiment, the number of the dampers 140 is two or more, and the dampers 140 are evenly spaced in the extension direction of the first pin 120. In one embodiment, the number of the dampers 140 is two, that is, the dampers 140 can be spaced at any position in the extension direction of the first pin 120. In another embodiment, the number of the dampers 140 is two or more, that is, the dampers 140 are evenly spaced in the extension direction of the first pin 120. Since the vibration of the capacitor 110 in the extension direction of the first pin 120 is relatively uniformly distributed, the uniform distribution of the vibration absorber 140 in the extension direction of the first pin 120 can increase the stability of the capacitor 110 during operation. When the capacitor 110 is working, the vibration of the capacitor 110 drives the multiple vibration absorbers 140 to move, so that the multiple vibration absorbers 140 will vibrate together with the capacitor 110, thereby transferring the deformation generated by the vibration of the capacitor 110 to the air in the accommodating space 150, that is, through the friction between the multiple vibration absorbers 140 and the air, the kinetic energy of the vibration of the multiple vibration absorbers 140 is converted into heat energy and dissipated into the air. At the same time, the air in the accommodating space 150 is repeatedly compressed and released as the multiple vibration absorbers 140 vibrate. In this process, friction occurs between the air and the multiple vibration absorbers 140 and the air molecules themselves, which will form a damping force on the vibration of the multiple vibration absorbers 140, suppressing the amplitude and frequency of the vibration of the multiple vibration absorbers 140. Since the plurality of vibration absorbers 140 jointly support the capacitor 110 , the amplitude and frequency of the vibration of the capacitor 110 are further reduced, which is more conducive to suppressing or even eliminating the howling generated during the operation of the capacitor 110 .
[0055] Please refer to Figure 4 and Figure 8 , Figure 8 for Figure 4Another distribution diagram of the vibration damper in the capacitor assembly provided in the embodiment. In this embodiment, the vibration damper 140 includes a first support member 141, or the vibration damper 140 includes a first support member 141 and a second support member 142. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 deviates from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. When the vibration damper 140 includes a second support member 142, the second support member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411 and is used to support the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is away from the capacitor 110 compared to the third free end 1421. The third free end 1421 can move relative to the fourth free end 1423. In addition, in this embodiment, the number of the dampers 140 is two or more. The capacitor component 100 has a first area 160, a middle area 170 and a second area 180 in sequence in the direction from the first pin 120 to the second pin 130. The first area 160 is arranged adjacent to the first pin 120. The second area 180 is arranged adjacent to the second pin 130. The middle area 170 is sandwiched between the first area 160 and the second area 180. The distribution density of the dampers 140 in the first area 160 is the first density. The distribution density in the second area 180 is the second density. The distribution density in the middle area 170 is the third density. The first density is greater than the third density, and the second density is greater than the third density. It should be noted that the schematic diagram of this embodiment is based on the number of the dampers 140 being two or more combined with Figure 4 The implementation method is illustrated in FIG. 1 , and it can be understood that Figure 8 The structural schematic diagram of the capacitor assembly 100 described in the figure does not limit the capacitor assembly 100 provided in the present application.
[0056] Since the capacitor 110 usually needs to be electrically connected to a circuit board through the first pin 120 and the second pin 130 to work, the first pin 120 and the second pin 130 on the capacitor 110 will contact the circuit board, so that the vibration of the capacitor 110 is transmitted to the circuit board through the first pin 120 and the second pin 130, which will cause the vibration of the circuit board to resonate with the vibration of the capacitor 110, so that the vibration amplitude near the first pin 120 and the second pin 130 increases. That is, the vibration amplitude of the capacitor 110 in the first area 160 and the second area 180 is greater than the density of the middle area 170.
[0057] In this embodiment, the vibration absorbers 140 are arranged at non-uniform intervals in the direction from the first pin 120 to the second pin 130. Specifically, the first density of the vibration absorbers 140 distributed in the first area 160 is greater than the third density of the vibration absorbers 140 distributed in the middle area 170, that is, the number of vibration absorbers 140 distributed per unit area in the first area 160 is greater than the number of vibration absorbers 140 distributed per unit area in the middle area 170. The second density of the vibration absorbers 140 distributed in the second area 180 is greater than the third density of the vibration absorbers 140 distributed in the middle area 170, that is, the number of vibration absorbers 140 distributed per unit area in the second area 180 is greater than the number of vibration absorbers 140 distributed per unit area in the middle area 170. By distributing the vibration absorbers 140 more densely in the first area 160 and the second area 180 relative to the middle area 170, it is possible to reduce vibration of the capacitor 110 in the first area 160 and the second area 180 where the vibration amplitude is larger, thereby more efficiently reducing the deformation of the capacitor 110, thereby suppressing the amplitude and frequency of vibration of the capacitor 110 during operation, making the capacitor 110 more stable during operation, thereby suppressing or even eliminating the howling generated by the capacitor 110 during operation.

In this embodiment, the vibration absorber 140 includes a first support member 141, or the vibration absorber 140 includes a first support member 141 and a second support member 142. The first support member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 is away from the capacitor 110 compared to the first free end 1411. The first free end 1411 can move relative to the second free end 1413. When the vibration absorber 140 includes a second support member 142, the second support member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411 and is used to support the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is away from the capacitor 110 compared to the third free end 1421. The third free end 1421 can move relative to the fourth free end 1423. In addition, in the present embodiment, the first pin 120 includes a first pin body 121 and a first bending portion 122. The first bending portion 122 is connected to the first pin body 121 and faces the second pin 130 compared to the first pin body 121.

Therefore, the first bending portion 122 and the second bending portion 132 jointly support the vibration absorber 140, and the vibration absorber 140 supports the capacitor 110, thereby increasing the stability of the vibration of the vibration absorber 140 and the capacitor 110 together, which is beneficial for the vibration absorber 140 to reduce the vibration amplitude and frequency of the capacitor 110, thereby suppressing or even eliminating the howling caused by the vibration of the capacitor 110.

[0067] Please refer to Fig.13 , Fig.13 for Fig. 9A schematic diagram of a structure in which a damper is fixedly connected to a capacitor in a capacitor assembly provided in an embodiment. In this embodiment, the first pin 120 includes a first pin body 121 and a first bent portion 122. The first bent portion 122 is connected to the first pin body 121 and faces the second pin 130 compared to the first pin body 121. The second pin 130 includes a second pin body 131 and a second bent portion 132. The second bent portion 132 is connected to the second pin body 131 and faces the first pin 120 compared to the second pin body 131. When the damper 140 includes a second support member 142, the first free end 1411 and the third free end 1421 are spaced apart in the direction from the first pin 120 to the second pin 130. The second free end 1413 is fixedly connected to the surface of the first bent portion 122 facing the capacitor 110. The fourth free end 1423 is fixedly connected to the surface of the second bent portion 132 facing the capacitor 110. Alternatively, when the shock absorber 140 includes a second support member 142, the first free end 1411 and the third free end 1421 are spaced apart in the extension direction of the first pin 120. The second free end 1413 is fixedly connected to the surface of the first bending portion 122 facing the capacitor 110 and the surface of the second bending portion 132 facing the capacitor 110, respectively. The fourth free end 1423 is fixedly connected to the surface of the first bending portion 122 facing the capacitor 110 and the surface of the second bending portion 132 facing the capacitor 110, respectively. In addition, in the present embodiment, the first free end 1411 and the third free end 1421 are fixedly connected to the capacitor 110, and the first free end 1411 and the third free end 1421 jointly support the capacitor 110. It should be noted that the schematic diagram of the present embodiment is based on the first free end 1411 and the third free end 1421 being fixedly connected to the capacitor 110 and combined to Fig. 9 The implementation method is illustrated in FIG. 1 , and it can be understood that Fig.11 The structural schematic diagram of the capacitor assembly 100 described in the figure does not limit the capacitor assembly 100 provided in the present application.
[0068] In this embodiment, the first free end 1411 and the third free end 1421 are fixedly connected to the capacitor 110, and the first free end 1411 and the third free end 1421 jointly support the capacitor 110. That is, the first support member 141 is fixedly connected to the capacitor 110 through the first free end 1411, and the first support member 141 supports the capacitor 110 through the first free end 1411. The second support member 142 is fixed to the capacitor 110 through the third free end 1421, and the second support member 142 supports the capacitor 110 through the third free end 1421. Therefore, the vibration damper 140 is fixedly connected to the capacitor 110 and supports the capacitor 110. When the capacitor 110 is working, the vibration of the capacitor 110 drives the first free end 1411 to move relative to the second free end 1413, and the vibration of the capacitor 110 drives the third free end 1421 to move relative to the fourth free end 1423, so that the vibration absorber 140 will vibrate together with the capacitor 110, thereby transferring the deformation generated by the vibration of the capacitor 110 to the vibration absorber 140, and the kinetic energy of the vibration of the vibration absorber 140 is converted into heat energy and dissipated into the air through the friction between the vibration absorber 140 and the air. At the same time, the air in the accommodating space 150 is repeatedly compressed and released with the vibration of the first support member 141 and the second support member 142. In this process, friction occurs between the air and the vibration absorber 140 and the air molecules themselves, which will form a damping force on the vibration of the vibration absorber 140, suppressing the amplitude and frequency of the vibration of the vibration absorber 140. Since the first free end 1411 and the third free end 1421 of the vibration absorber 140 are fixedly connected to the capacitor 110 and support the capacitor 110, the vibration frequency of the capacitor 110 is reduced, thereby suppressing or even eliminating the howling generated by the capacitor 110 during operation.

The first free end 1411 and the third free end 1421 are fixedly connected to the capacitor 110, and the first free end 1411 and the third free end 1421 jointly support the capacitor 110. In addition, in this embodiment, the first support member 141 elastically abuts against the capacitor 110 and the first bending portion 122. The second support member 142 elastically abuts against the capacitor 110 and the second bending portion 132. It should be noted that the schematic diagram of this embodiment is that the damper 140 elastically abuts against the capacitor 110 and the first pin 120 and the second pin 130 are combined to Fig.11 The implementation method is illustrated in FIG. 1 , and it can be understood that Fig.12 The structural schematic diagram of the capacitor assembly 100 described in the figure does not limit the capacitor assembly 100 provided in the present application.
[0070] In this embodiment, the vibration damper 140 elastically abuts against the capacitor 110 and the first bending portion 122 through the first supporting member 141, and elastically abuts against the capacitor 110 and the second bending portion 132 through the second supporting member 142. Specifically, when the capacitor 110 is not working, the first free end 1411 has the potential energy to move away from the second free end 1413, and the third free end 1421 has the potential energy to move away from the fourth free end 1423. Therefore, the vibration damper 140 has the elastic potential energy to support the capacitor 110 in the direction away from the vibration damper 140. When the capacitor 110 is working, it is usually connected to a circuit board for operation, so the vibration of the capacitor 110 will be transmitted toward the circuit board. Since the vibration absorber 140 has elastic potential energy opposite to the vibration propagation, the elasticity of the vibration absorber 140 that can recover through deformation will form resistance to the vibration of the capacitor 110, which can further suppress the amplitude and frequency of the vibration of the capacitor 110, thereby suppressing or even eliminating the howling generated by the capacitor 110 during operation.

[0073] When the capacitor 110 is working, it will produce a howl due to its own high vibration frequency. At the same time, when the capacitor 110 is powered on and working on the circuit board 200, the capacitor 110 will also drive the circuit board 200 to vibrate, so that the capacitor 110 and the circuit board 200 will produce a howl due to vibration.
[0074] In this embodiment, the capacitor assembly 100 is electrically connected to the circuit board 200 through the conductive member 300, so that the capacitor assembly 100 is electrically connected to the circuit board 200.

In addition, the first bending portion 122 and the second bending portion 132 are electrically connected to the circuit board 200 through the conductive member 300 to form a bottom connection of the capacitor assembly 100, so that the connection between the capacitor assembly 100 and the circuit board 200 is more firm and stable.
[0075] In this embodiment, the vibration damper 140 can not only reduce the vibration amplitude and frequency of the capacitor 110, but also play a buffering role between the capacitor 110 and the circuit board 200 to suppress or even eliminate the resonance between the capacitor 110 and the circuit board 200, thereby suppressing or even eliminating the howling generated when the capacitor 110 works on the circuit board 200.

In another embodiment, the cut-off frequency f0 of the low-pass filter circuit is 120 Hz, the frequency f1 of the first current is in the range of 20 Hz ≤ f1 ≤ 200 Hz, and the frequency f2 of the second current is in the range of 20 Hz ≤ f2 ≤ 120 Hz.
