Liquid crystal display devices will make a "chirping" sound during operation, and this phenomenon is called "howling". One of the reasons for the "howling" is the vibration of the inductor. It can be seen that due to the existence of "howling", the quality of liquid crystal display devices in related technologies is not high. Summary of the invention

When the inductor is working, the vibration of the inductor drives the first free end to move relative to the second free end, so that the shock absorber will vibrate with the inductor, thereby transferring the deformation generated by the vibration of the inductor to the air in the shock absorber, that is, the kinetic energy of the vibration of the shock absorber is converted into heat energy and dissipated into the air through the friction between the shock absorber and the air. At the same time, the air in the shock absorber is repeatedly compressed and released with the vibration of the first support member, and during this process, friction occurs between the air and the shock absorber and the air, thereby forming a damping force on the vibration of the shock absorber, thereby suppressing the amplitude and frequency of the vibration of the shock absorber. Since the first free end of the shock absorber supports the inductor, the vibration frequency of the inductor is reduced. Therefore, the inductor component provided by the present application can reduce the vibration frequency of the inductor through the vibration damper to suppress or even eliminate the howling generated during the operation of the inductor. When the inductor component is applied to a liquid crystal display device, the liquid crystal display device has higher quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The present application provides an inductor assembly 100. Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of an inductor assembly provided in the first embodiment of the present application. In the first embodiment, the inductor assembly 100 includes an inductor 110 and a vibration damper 120. The vibration damper 120 includes a first support member 121, and the first support member 121 has a first free end 1211, a first connecting portion 1212, and a second free end 1213 connected in sequence. The first free end 1211 is used to support the inductor 110, and the second free end 1213 is away from the inductor 110 compared to the first free end 1211, and the first free end 1211 can move relative to the second free end 1213.

[0035] The inductor 110 provided in the embodiment of the present application may be an unshielded inductor or a shielded inductor, which will be described in detail later. Figure 2 , Figure 2It is a schematic diagram of the structure of an unshielded inductor. The inductor 110 is also called an inductor. The inductor 110 is a component that can convert electrical energy into magnetic energy and store it. The inductor 110 is widely used in circuits. Usually, the inductor 110 mainly plays the role of filtering, oscillating, delaying, trapping, screening signals, stabilizing current and suppressing electromagnetic interference in the circuit. The inductor 110 generally includes a winding 114 and a magnetic body 115. The winding 114 is generally a group of coils. The winding 114 is wound on the outer surface of the magnetic body 115. After the winding 114 is energized, the electrical energy is converted into magnetic energy through the principle of electromagnetic induction, and the magnetic energy is stored in the magnetic body 115. In one embodiment, the magnetic body 115 is a magnetic core, and the magnetic body 115 itself has a magnetic field. For example, the magnetic core is generally made of nickel-zinc ferrite (NX series) or manganese-zinc ferrite (MX series), and the shape of the magnetic core can be, but not limited to, an I-shaped, columnar, cap-shaped, "E"-shaped, or a can-shaped, etc. In another embodiment, the magnetic body 115 is an iron core, and the magnetic body 115 itself does not have a magnetic field, but has magnetic conductivity. For example, the iron core is generally made of silicon steel sheet or Permalloy, and the shape of the iron core can be, but not limited to, an I-shaped, columnar, cap-shaped, "E"-shaped, or a can-shaped, etc.

[0036] Please refer to Figure 3 , Figure 3 Schematic diagram of the structure of a shielded inductor. On the one hand, the inductor 110 itself generates a magnetic field during operation. On the other hand, there are magnetic fields generated by other components in the working environment of the inductor 110. The above magnetic fields will affect the winding 114. The shielded inductor uses a shielding member 116 to enclose the winding 114, so that the winding 114 is isolated from the magnetic field outside the shielding member 116 and is not affected by the external magnetic field. Figure 2 The unshielded inductor shown does not have the shielding member 116 . Since there is no shielding member 116 to isolate the winding 114 from the external magnetic field, the external magnetic field may interfere with the winding 114 .

[0037] When the inductor 110 is powered on, the winding 114 and the magnetic body 115 will generate a magnetic field due to electromagnetic induction, and the magnetic body 115 will undergo magnetostriction in the magnetic field, which will cause a slight change in the shape of the magnetic body 115. Although the change is small, the magnetic body will repeatedly expand and contract during the power-on process, which will accelerate the vibration frequency of the inductor, causing the inductor 110 to emit a whistling sound. For unshielded inductors, the winding 114 and the magnetic body 115 will generate a magnetic field due to electromagnetic induction, and the magnetic field generated by other components in the working environment will also act on the winding 114, causing the winding 114 to vibrate repeatedly, further causing the inductor 110 to produce a whistling sound. It should be noted that the vibration of the magnetic body 115 is the main reason for the whistling of the inductor 110.

[0038] The first support member 121 is elastic. In one embodiment, the first support member 121 is made of an elastic material, so that the first free end 1211 can move relative to the second free end 1213. For example, the first support member 121 can be rubber, latex or elastic fiber. In another embodiment, the first support member 121 is made of a material with relatively high hardness, and the material of the first support member 121 itself is not very elastic, or even has no elasticity. The first support member 121 is elastic due to its own shape, so that the first free end 1211 can move relative to the second free end 1213. For example, the first support member 121 can be made of iron, steel or hard plastic. Since the first support member 121 includes the first free end 1211, the first connecting portion 1212 and the second free end 1213 connected in sequence, the second free end 1213 can move relative to the first free end 1211. Therefore, the first support member 121 can be in a "C" shape, a "Z" shape or an "O" shape. In one embodiment, the first support member 121 is non-conductive, which can prevent the first support member 121 from affecting the magnetic circuit or electrical performance of the inductor 110, and is conducive to the vibration reduction of the inductor 110 by the vibration absorber 120, thereby suppressing or even eliminating the howling.

[0039] The first support member 121 has a first free end 1211, a first connection portion 1212 and a second free end 1213 connected in sequence, and the first connection portion 1212 can be connected to the first free end 1211 and the second free end 1213 by a bending shape or an arc shape, but is not limited to the bending shape or the arc shape, as long as the first free end 1211 can move relative to the second free end 1213. In the inductor component 100 provided in the embodiment of the present application, the first free end 1211 supports the inductor 110, and the first free end 1211 can move relative to the second free end 1213, and the first free end 1211 does not break away from the connection with the first connection portion 1212, but is realized by elastic deformation generated by the elasticity of the first support member 121 itself. The first free end 1211 can move closer to the second free end 1213 or move away from the second free end 1213.

[0040] In order to prevent the inductor 110 from producing whistles during operation, the inductor assembly 100 provided in the present application includes an inductor 110 and a vibration absorber 120. The vibration absorber 120 includes a first support member 121, wherein the first support member 121 has a first free end 1211, a first connecting portion 1212, and a second free end 1213 connected in sequence, wherein the first free end 1211 is used to support the inductor 110, and the second free end 1213 is away from the inductor 110 compared to the first free end 1211, and the first free end 1211 can move relative to the second free end 1213. When the inductor 110 is working, the vibration of the inductor 110 drives the first free end 1211 to move relative to the second free end 1213, so that the shock absorber 120 will vibrate together with the inductor 110, thereby transferring the deformation generated by the vibration of the inductor 110 to the shock absorber 120, and converting the kinetic energy of the vibration of the shock absorber 120 into heat energy and dissipating it into the air through the friction between the shock absorber 120 and the air. At the same time, the air in the shock absorber 120 is repeatedly compressed and released as the first support member 121 vibrates. During this process, friction occurs between the air and the shock absorber 120 and between the air, which will form a damping force on the vibration of the shock absorber 120, thereby suppressing the amplitude and frequency of the vibration of the shock absorber 120. Since the first free end 1211 of the shock absorber 120 supports the inductor 110, the vibration frequency of the inductor 110 is reduced. Therefore, the inductor assembly 100 provided in the present application can reduce the vibration frequency of the inductor 110 through the vibration absorber 120 to suppress or even eliminate the howling generated during the operation of the inductor 110 .

[0041] Please refer to Figure 4 , Figure 4A schematic diagram of the elastic deformation of the shock absorber provided in the second embodiment of the present application. The first free end 1211 moves relative to the second free end 1213, and the stroke L1 of the first free end 1211 relative to the second free end 1213 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 1211 relative to the second free end 1213 is introduced below. When the first support member 121 is in a natural state (state a), the distance between the first free end 1211 and the second free end 1213 is L 11 When the first support member 121 is in the maximum compression state (state b), the distance between the first free end 1211 and the second free end 1213 is L 12 When the first support member 121 is in the maximum tension state (state c), the distance between the first free end 1211 and the second free end 1213 is L 13 Then, the maximum travel of the first free end 1211 moving toward the second free end 1213 is: L1 = L 11 -L 12 The maximum travel of the first free end 1211 moving away from the second free end 1213 is L1 = L 13 -L 11. In the present embodiment, both the maximum stroke L1 of the first free end 1211 moving toward the direction close to the second free end 1213 and the maximum stroke L1 of the first free end 1211 moving away from the second free end 1213 satisfy 1mm≤L1≤1.5mm. It should be noted that the maximum stroke of the first free end 1211 moving toward the direction close to the second free end 1213 may be equal to or unequal to the maximum stroke of the first free end 1211 moving away from the second free end 1213. If the stroke L1 of the first free end 1211 moving relative to the second free end 1213 is greater than 1.5mm, the vibration amplitude of the inductor 110 will be too large, which may cause the first free end 1211 to contact or even collide with the second free end 1213, affecting the vibration reduction effect of the first support member 121. If the stroke L1 of the first free end 1211 relative to the second free end 1213 is less than 1 mm, the first support member 121 will not be able to provide a sufficiently strong damping force during the vibration of the inductor 110, which will affect the vibration reduction effect of the first support member 121. By limiting the stroke L1 of the first free end 1211 relative to the second free end 1213, the first support member 121 provides a sufficiently strong damping force during the vibration of the inductor 110, thereby reducing the vibration amplitude and frequency of the inductor 110, and suppressing or even eliminating the howling caused by the vibration of the inductor 110.

[0042] Please refer to Figure 5 , Figure 5 A schematic diagram of the structure of the inductor assembly provided in the third embodiment of the present application. In the third embodiment, the shock absorber 120 further includes a second support member 122, and the second support member 122 has a third free end 1221, a second connecting portion 1222, and a fourth free end 1223 connected in sequence. The third free end 1221 is spaced apart from the first free end 1211 and is used to support the inductor 110. The second connecting portion 1222 is connected to the first connecting portion 1212. The fourth free end 1223 is away from the inductor 110 compared to the third free end 1221, and the third free end 1221 can move relative to the fourth free end 1223.

[0043] The second support member 122 is elastic. In one embodiment, the second support member 122 is made of an elastic material, so that the third free end 1221 can move relative to the fourth free end 1223. For example, the second support member 122 can be made of rubber, latex or elastic fiber. In another embodiment, the second support member 122 is made of a material with relatively high hardness, and the material of the second support member 122 itself is not very elastic, or even has no elasticity. The second support member 122 is elastic due to its own shape, so that the third free end 1221 can move relative to the fourth free end 1223. For example, the second support member 122 can be made of iron, steel or hard plastic. Since the second support member 122 includes the third free end 1221, the second connecting portion 1222 and the fourth free end 1223 connected in sequence, the third free end 1221 can move relative to the fourth free end 1223. Therefore, the second support member 122 can be in a "C" shape, a "Z" shape or an "O" shape. In another embodiment, the second support member 122 is non-conductive, which can prevent the second support member 122 from affecting the magnetic circuit or electrical performance of the inductor 110, and is conducive to the vibration reduction of the inductor 110 by the vibration absorber 120, thereby suppressing or even eliminating the howling.

[0044] In one embodiment, the first support member 121 is in an inverted "C" shape, and the second support member 122 is in a "C" shape. Since the second connection portion 1222 is connected to the first connection portion 1212, the first support member 121 and the second support member 122 are in an "X" shape.

[0045] The second support member 122 has a third free end 1221, a second connection portion 1222 and a fourth free end 1223 connected in sequence. The second connection portion 1222 can be connected to the third free end 1221 and the fourth free end 1223 by a bending shape or an arc shape, but is not limited to the bending shape or the arc shape, as long as the third free end 1221 can move relative to the fourth free end 1223. The movement of the third free end 1221 relative to the fourth free end 1223 does not cause the third free end 1221 to be disconnected from the second connection portion 1222, but is achieved by elastic deformation generated by the elasticity of the second support member 122 itself. The third free end 1221 can move closer to the fourth free end 1223 or move away from the fourth free end 1223.

[0046] The third free end 1221 is used to support the inductor 110, and the third free end 1221 and the inductor 110 move together, that is, the third free end 1221 and the inductor 110 can move together relative to the fourth free end 1223. Since the third free end 1221 and the first free end 1211 are spaced apart, and the third free end 1221 and the first free end 1211 are both used to support the inductor 110, the third free end 1221 and the first free end 1211 jointly support the inductor 110. At the same time, the second connecting portion 1222 is connected to the first connecting portion 1212, so that the second supporting member 122 and the first supporting member 121 can vibrate with the inductor 110 at the same time, that is, when the third free end 1221 moves relative to the fourth free end 1223, the first free end 1211 also moves relative to the second free end 1213. The second support member 122 and the first support member 121 jointly support the inductor 110 and vibrate along with the vibration of the inductor 110 , so that the inductor 110 is more stable during the vibration process.

[0047] When the inductor 110 is working, the vibration of the inductor 110 drives the third free end 1221 and the first free end 1211 to move relative to the fourth free end 1223 and the second free end 1213, so that the shock absorber 120 will vibrate together with the inductor 110, thereby transferring the deformation generated by the vibration of the inductor 110 to the air in the shock absorber 120, that is, the kinetic energy of the vibration of the shock absorber 120 is converted into heat energy and dissipated into the air through the friction between the shock absorber 120 and the air. At the same time, the air in the shock absorber 120 is repeatedly compressed and released with the vibration of the first support member 121 and the second support member 122. During this process, friction occurs between the air and the shock absorber 120 and between the air, which forms a damping force on the vibration of the shock absorber 120, thereby suppressing the amplitude and frequency of the vibration of the shock absorber 120. Since the first free end 1211 and the third free end 1221 of the vibration absorber 120 jointly support the inductor 110, the vibration frequency of the inductor 110 is reduced. Therefore, the inductor assembly 100 provided in the third embodiment can reduce the vibration frequency of the inductor 110 through the vibration absorber 120 to suppress or even eliminate the howling generated during the operation of the inductor 110.

[0048] Please refer to Figure 6 , Figure 6A schematic diagram of the structure of an inductor assembly provided in the fourth embodiment of the present application. In the fourth embodiment, the first free end 1211 is disconnected from the second free end 1213 to form a first opening 1214, the third free end 1221 is disconnected from the fourth free end 1223 to form a second opening 1224, and the second opening 1224 is oriented away from the first opening 1214.

[0049] In this embodiment, the first free end 1211 is disconnected from the second free end 1213 to form the first opening 1214, so that the first support member 121 has the first opening 1214. The third free end 1221 is disconnected from the fourth free end 1223 to form the second opening 1224, so that the second support member 122 has the second opening 1224. Since the inductor 110 exhibits a small amplitude and high frequency vibration during operation, it is difficult to perceive the vibration of the inductor 110, and a high elasticity requirement is imposed on the vibration absorber 120. Under the premise that the first support member 121 and the second support member 122 have elasticity, the first opening 1214 and the second opening 1224 enable the first support member 121 and the second support member 122 to improve their own elasticity by using their shapes, so that the vibration absorber 120 can more easily capture the vibration of the inductor 110 and vibrate along with the inductor 110, and the first support member 121 and the second support member 122 form a damping force on the vibration of the inductor 110, reduce the amplitude and frequency of the vibration of the inductor 110, thereby suppressing or even eliminating the howling caused by the vibration of the inductor 110. It should be noted that the first free end 1211 and the second free end 1213 can be connected by the first arc-shaped connecting portion 1212, or by the first connecting portion 1212 with a bent shape, as long as the shape of the first support member 121 can further increase the elasticity of the first support member 121. The third free end 1221 and the fourth free end 1223 may be connected via the arc-shaped second connection portion 1222 or via the bent second connection portion 1222 , as long as the shape of the second support member 122 can further increase the elasticity of the second support member 122 .

[0050] Please refer to Figure 7 , Figure 7A schematic diagram of the structure of the inductor assembly provided in the fifth embodiment of the present application. In the fifth embodiment, the first support member 121 and the second support member 122 have no openings. When the inductor 110 is working, the vibration of the inductor 110 drives the first support member 121 and the second support member 122 to vibrate, and the air in the first support member 121 and the second support member 122 is repeatedly compressed and released as the first support member 121 and the second support member 122 vibrate. In this process, the friction between the air and the first support member 121, the second support member 122 and the air will form a damping force on the vibration of the inductor 110. Since the first support member 121 and the second support member 122 have no openings, during the vibration of the first support member 121 and the second support member 122, the friction between the air in the first support member 121 and the second support member 122 and the first support member 121, the second support member 122 and the air is more intense, which further improves the damping force on the vibration of the inductor 110, suppresses the vibration amplitude and frequency of the inductor 110, and further suppresses or even eliminates the howling generated during the operation of the inductor 110.

[0051] Please refer to Figure 8 , Figure 8 Schematic diagram of elastic deformation of the shock absorber provided in the sixth embodiment of the present application. In the sixth embodiment, the first free end 1211 moves relative to the second free end 1213, and the stroke L1 of the first free end 1211 relative to the second free end 1213 satisfies: 1mm≤L1≤1.5mm. The stroke L2 of the third free end 1221 relative to the fourth free end 1223 satisfies: 1mm≤L2≤1.5mm.

[0052] 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 following is an introduction to the travel L1 of the first free end 1211 relative to the second free end 1213. When the first support member 121 is in a natural state (state A), the distance between the first free end 1211 and the second free end 1213 is L 11 When the first support member 121 is in the maximum compression state (state B), the distance between the first free end 1211 and the second free end 1213 is L 12 When the first support member 121 is in the maximum tension state (state C), the distance between the first free end 1211 and the second free end 1213 is L 13 Then, the maximum travel L1 of the first free end 1211 moving toward the second free end 1213 is: L1 = L11 -L 12 The maximum travel of the first free end 1211 moving in a direction away from the second free end 1213 is: L1 = L 13 -L 11 . In the present embodiment, both the maximum stroke L1 of the first free end 1211 moving toward the direction close to the second free end 1213 and the maximum stroke L1 of the first free end 1211 moving away from the second free end 1213 satisfy 1mm≤L1≤1.5mm. It should be noted that the maximum stroke of the first free end 1211 moving toward the direction close to the second free end 1213 may be equal to or unequal to the maximum stroke of the first free end 1211 moving away from the second free end 1213. If the stroke L1 of the first free end 1211 moving relative to the second free end 1213 is greater than 1.5mm, the vibration amplitude of the inductor 110 will be too large, which may cause the first free end 1211 to contact or even collide with the second free end 1213, affecting the vibration reduction effect of the first support member 121. If the stroke L1 of the first free end 1211 relative to the second free end 1213 is less than 1 mm, the first support member 121 will not be able to provide a sufficiently strong damping force during the vibration of the inductor 110, which will affect the vibration reduction effect of the first support member 121. By limiting the stroke L1 of the first free end 1211 relative to the second free end 1213, the first support member 121 provides a sufficiently strong damping force during the vibration of the inductor 110, thereby reducing the vibration amplitude and frequency of the inductor 110, and suppressing or even eliminating the howling caused by the vibration of the inductor 110.

[0053] 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 1221 relative to the fourth free end 1223. When the second support member 122 is in the natural state (state A), the distance between the third free end 1221 and the fourth free end 1223 is L 21 When the second support member 122 is in the maximum compression state (state B), the distance between the third free end 1221 and the fourth free end 1223 is L 22 When the second support member 122 is in the maximum stretching state (state C), the distance between the third free end 1221 and the fourth free end 1223 is L 23 Then, the maximum travel L2 of the third free end 1221 moving toward the fourth free end 1223 is: L2 = L21 -L 22 The maximum travel L2 of the third free end 1221 moving in a direction away from the fourth free end 1223 is: L2 = L 23 -L 21 . In this embodiment, both the maximum stroke L2 of the third free end 1221 moving toward the direction close to the fourth free end 1223 and the maximum stroke L2 of the third free end 1221 moving away from the fourth free end 1223 satisfy 1mm≤L2≤1.5mm. It should be noted that the maximum stroke of the third free end 1221 moving toward the direction close to the fourth free end 1223 may be equal to or unequal to the maximum stroke of the third free end 1221 moving away from the fourth free end 1223. If the stroke L2 of the third free end 1221 moving relative to the fourth free end 1223 is greater than 1.5mm, the vibration amplitude of the inductor 110 will be too large, which may cause the third free end 1221 to contact or even collide with the fourth free end 1223, affecting the vibration reduction effect of the second support member 122. If the stroke L2 of the third free end 1221 relative to the fourth free end 1223 is less than 1 mm, the second support member 122 will not be able to provide a sufficiently strong damping force during the vibration of the inductor 110, which will affect the vibration reduction effect of the second support member 122. By limiting the stroke L2 of the third free end 1221 relative to the fourth free end 1223, the second support member 122 can provide a sufficiently strong damping force during the vibration of the inductor 110, thereby reducing the vibration amplitude and frequency of the inductor 110, and suppressing or even eliminating the howling caused by the vibration of the inductor 110.

[0054] For example, in one embodiment, when the vibration frequency f of the inductor 110 satisfies: 1KHz≤f≤20KHz, a howling that is easily perceived by the human ear will be generated. In response to the howling caused by the vibration of the inductor 110, by limiting the travel L1 of the first free end 1211 relative to the second free end 1213 and the travel L2 of the third free end 1221 relative to the fourth free end 1223, the damping force of the shock absorber 120 is increased, the amplitude and frequency of the shock absorber 120 are reduced, and the vibration frequency of the inductor 110 is reduced, so that the vibration frequency f of the inductor 110 satisfies: f<1KHz, thereby suppressing or even eliminating the howling caused by the vibration of the inductor 110. It should be noted that in different application environments, the requirements for the vibration frequency of the inductor 110 are not the same, and this embodiment is only for reference.

[0055] Please refer to Fig. 9 , Fig. 9A schematic diagram of the structure of the inductor assembly provided in the seventh embodiment of the present application. In the seventh embodiment, the vibration absorber 120 further includes a first supporting member 123. The first supporting member 123 connects the first free end 1211 and the third free end 1221, and the first free end 1211 and the third free end 1221 support the inductor 110 through the first supporting member 123.

[0056] In this embodiment, the first supporting member 123 connects the first free end 1211 and the third free end 1221, and the first supporting member 123 supports the inductor 110. Compared with the first free end 1211 and the third free end 1221 directly supporting the inductor 110, the first supporting member 121 can provide a larger supporting surface for supporting the inductor 110, so that the inductor 110 is more stable during vibration.

[0057] In this embodiment, the first bearing member 123 may be, but is not limited to, a plate or a block, and the shape of the first bearing member 123 is not limited as long as the first bearing member 123 can increase the supporting surface of the vibration absorber 120 for the inductor 110 .

[0058] In this embodiment, the first carrier 123 and the first free end 1211 and the third free end 1221 can be integrated or connected by an adhesive. For example, the first carrier 123 can be connected to the first free end 1211 and the third free end 1221 by an adhesive. In one embodiment, the adhesive is 502 glue or hot melt adhesive. In another embodiment, the adhesive is 704 silicone adhesive or polyurethane adhesive, and a high temperature resistant and aging resistant adhesive with a long service life is used, so as to ensure that the effect of the adhesive will not be affected even if the inductor 110 is heated during operation.

[0059] In this embodiment, while the first carrier 123 supports the inductor 110, the first carrier 123 is connected to the inductor 110, so that the first carrier 123 and the inductor 110 can vibrate together. The first carrier 123 can be connected to the inductor 110 through an adhesive. In one embodiment, the adhesive is 502 glue or hot melt adhesive. In another embodiment, the adhesive is 704 silicone adhesive or polyurethane adhesive, etc., and an adhesive with high temperature resistance, aging resistance and long service life is used, so as to ensure that the heat generated during the operation of the inductor 110 will not affect the connection effect between the first carrier 123 and the inductor 110.

[0060] Please refer to Fig.10 , Fig.10The schematic diagram of the structure of the inductor assembly provided in the eighth embodiment of the present application is as follows. In the eighth embodiment, the vibration absorber 120 further includes a second bearing member 124. The second bearing member 124 connects the second free end 1213 and the fourth free end 1223.

[0061] In this embodiment, the second supporting member 124 connects the second free end 1213 and the fourth free end 1223. Compared with the second free end 1213 and the fourth free end 1223 directly supporting the vibration of the shock absorber 120, the second supporting member 122 can provide a larger supporting surface for supporting the vibration of the shock absorber 120, so that the shock absorber 120 is more stable during the vibration of the inductor 110.

[0062] In this embodiment, the second bearing member 124 may be, but is not limited to, a plate or a block, and the shape of the second bearing member 124 is not limited as long as the second bearing member 124 can increase a supporting surface for supporting the vibration of the shock absorber 120 .

[0063] In this embodiment, the second carrier 124 and the second free end 1213 and the fourth free end 1223 may be integrated or connected by a bonding member. For example, the second carrier 124 may be connected to the second free end 1213 and the fourth free end 1223 by a bonding member. In one embodiment, the bonding member is 502 glue or hot melt adhesive. In another embodiment, the bonding member is 704 silicone adhesive or polyurethane adhesive, and a bonding member with high temperature resistance, aging resistance and long service life is used, so as to ensure that the effect of the bonding member will not be affected even if the inductor 110 is heated during operation.

[0064] In this embodiment, the second carrier 124 is parallel to the first carrier 123, which can further increase the stability of the vibration absorber 120, so that during the vibration of the inductor 110, the vibration of the vibration absorber 120 and the inductor 110 is more stable, which is conducive to further suppressing or even eliminating the howling caused by the vibration of the inductor 110.

[0065] Please refer to Fig.11 , Fig.11A schematic diagram of the structure of the inductor assembly provided in the ninth embodiment of the present application. In the ninth embodiment, the line M connecting the center O1 of the vibration absorber 120 and the center O2 of the inductor 110 is perpendicular to the first carrier 123, so that the vibration absorber 120 vibrates more smoothly with the inductor 110, which is conducive to further suppressing or even eliminating the howling caused by the vibration of the inductor 110. If the line M connecting the center O1 of the vibration absorber 120 and the center O2 of the inductor 110 is not perpendicular to the first carrier 123, it is easy for the inductor 110 to vibrate and deviate during the vibration process, and may even aggravate the vibration amplitude of the inductor 110.

[0066] Please refer to Fig.12 , Fig.12 A schematic diagram of the structure of an inductor assembly provided in the tenth embodiment of the present application. In the tenth embodiment, the inductor 110 includes an inductor body 111, a first pin 112 and a second pin 113, wherein the first pin 112 and the second pin 113 are both disposed at one end of the inductor body 111. The first pin 112 includes a first pin body 1121 and a first bending portion 1122 connected in a bent manner, wherein the first bending portion 1122 faces the second pin 113 compared to the first pin body 1121. The second pin 113 includes a second pin body 1131 and a second bending portion 1132, wherein the second pin body 1131 and the first pin body 1121 are spaced apart to form an accommodation space, wherein the accommodation space is used to accommodate the damper 120, wherein the second bending portion 1132 faces the first pin 112 compared to the second pin body 1131. The first bending portion 1122 and the second bending portion 1132 abut against the end surface of the second carrier 124 away from the first carrier 123.

[0067] In this embodiment, the first bent portion 1122 and the second bent portion 1132 abut against the end surface of the second carrier 124 away from the first carrier 123, so that the connection between the vibration absorber 120 and the inductor 110 is more stable, thereby increasing the synergy of the vibration of the vibration absorber 120 and the inductor 110, which is beneficial for the vibration absorber 120 to reduce the vibration amplitude and frequency of the inductor 110, thereby suppressing or even eliminating the howling of the inductor 110 caused by vibration.

[0068] In this embodiment, the inductor 110 usually needs to be installed on a circuit board through conductive parts such as solder and conductive glue. The first bending portion 1122 and the second bending portion 1132 can increase the installation area of ​​the inductor 110, making the subsequent installation and application of the inductor 110 more stable and firm.

[0069] Please refer to Fig.13 , Fig.13A schematic diagram of the structure of the inductor assembly provided in the eleventh embodiment of the present application. In the eleventh embodiment, in the extension direction of the first pin body 1121, the difference δ between the size of the damper 120 and the size of the inductor body 111 satisfies: |δ|≤1mm. The extension direction of the first pin body 1121 is perpendicular to the stacking direction of the inductor body 111 and the damper 120.

[0070] In this embodiment, the extending direction of the first pin body 1121 refers to the direction in which the damper 120 is not wrapped by the inductor 110, that is, Fig.13 In the direction indicated by the indicator line D or the opposite direction. In the extension direction of the first pin body 1121, the size difference δ between the shock absorber 120 and the inductor body 111 needs to satisfy: |δ|≤1mm. If the size of the shock absorber 120 is too small, the support of the inductor 110 by the shock absorber 120 will be insufficient. If the size of the shock absorber 120 is too large, it will affect the installation of other components when the inductor 110 is actually installed on the circuit board 200. Therefore, in the extension direction of the first pin body 1121, the size difference δ between the shock absorber 120 and the inductor body 111 satisfies: |δ|≤1mm, which enables the shock absorber 120 to provide more stable support to the inductor 110 without affecting the installation of the inductor 110 in actual applications.

[0071] The present application also provides a circuit board assembly 10. Fig.14 , Fig.14 A schematic diagram of the structure of a circuit board assembly provided in an embodiment of the present application. In the eleventh embodiment, the circuit board assembly 10 comprises a circuit board 200 and the inductor assembly 100 as described above, and the inductor assembly 100 is electrically connected to the circuit board 200 .

[0072] When the inductor 110 is working, it will produce a howl due to its own high vibration frequency. At the same time, when the inductor 110 is powered on the circuit board 200, the inductor 110 will also drive the circuit board 200 to vibrate, so that the inductor 110 and the circuit board 200 will produce a howl due to resonance.

[0073] In this embodiment, the inductor component 100 is electrically connected to the circuit board 200 through the conductive member 130, so that the inductor component 100 is electrically connected to the circuit board 200. The conductive member 130 can be, but is not limited to, solder or conductive glue. In one embodiment, the first pin body 1121 and the second pin body 1131 are electrically connected to the circuit board 200 through the conductive member 130 to form a side connection of the inductor component 100. In another embodiment, the first pin body 1121 and the second pin body 1131 are electrically connected to the circuit board 200 through the conductive member 130 to form a side connection of the inductor component 100, and at the same time, the bent portion is electrically connected to the circuit board 200 through the conductive member 130 to form a bottom connection of the inductor component 100, so that the connection between the inductor component 100 and the circuit board 200 is more firm and stable.

[0074] In this embodiment, the circuit board 200 may be, but is not limited to, a functional circuit such as a boost circuit, a buck circuit or a power supply circuit.

[0075] In this embodiment, the vibration absorber 120 can not only reduce the vibration amplitude and frequency of the inductor 110, but also play a buffering role between the inductor 110 and the circuit board 200 to suppress or even eliminate the resonance between the inductor 110 and the circuit board 200, thereby suppressing or even eliminating the howling generated when the inductor 110 works on the circuit board 200.

[0076] The present application also provides a liquid crystal display device 1. Fig.15 , Fig.15 A circuit block diagram of a liquid crystal display device provided in an embodiment of the present application. In this embodiment, the liquid crystal display device 1 includes a liquid crystal display panel 20 and a circuit board assembly 10 as described above, and the circuit board assembly 10 is electrically connected to the liquid crystal display panel 20 .

[0077] In this embodiment, the vibration amplitude and frequency of the inductor 110 and the circuit board 200 are reduced by the vibration absorber 120, and the resonance between the inductor 110 and the circuit board 200 is suppressed or even eliminated, thereby suppressing or even eliminating the howling generated by the inductor 110 when working in the liquid crystal display device 1.

[0078] In this embodiment, for example, the circuit board 200 is a control panel, the inductor 110 works as a part of a boost circuit on the circuit board 200, the circuit board 200 boosts the input first voltage to a second voltage, and provides the second voltage to the liquid crystal display panel 20, thereby driving the liquid crystal display panel 20 to work. For example, in one embodiment, the first voltage is 1.2V, and the second voltage is 15V, in other words, the circuit board 200 boosts 1.2V to 15V. In another embodiment, the first voltage is 1.8V, and the second voltage is 30V, in other words, the circuit board 200 boosts 1.8V to 30V. For example, the circuit board 200 is a control panel, the inductor 110 works as a part of a step-down circuit on the circuit board 200, the circuit board 200 steps down the input third voltage to a fourth voltage and provides it to the liquid crystal display panel 20, thereby driving the liquid crystal display panel 20 to work. For example, in one embodiment, the third voltage is 12V and the fourth voltage is 3.3V, in other words, the circuit board 200 steps down 12V to 3.3V. In another embodiment, the third voltage is 15V and the fourth voltage is 1.2V, in other words, the circuit board 200 steps down 15V to 1.2V.
