[0002] With the rapid development of modern science and technology, people have an increasing demand for electronic products. Electronic products are prone to malfunction due to vibration and impact during use. Vibration will have an adverse effect on the operation of electronic products such as audio equipment, and will also shorten the service life of electronic products. Although there are many vibration reduction devices on the market, most of them are fixed to the bottom of electronic products using rubber and spring seats to buffer and isolate their vibration. However, due to the diversification of electronic products, the above vibration reduction devices are usually set up in pairs, which cannot adapt to a variety of electronic products, have poor vibration reduction effects and a narrow scope of application.

The lamp speaker requires a matching vibration-damping bracket fixedly arranged at the bottom of the speaker to reduce the transmission of the vibration energy of the speaker, and the vibration-damping bracket also needs to be wrapped with a matching elastic colloid, but the vibration-damping bracket is relatively large in size, inconvenient to move and carry, and has a narrow scope of application.

[0023] Embodiment 1

[0024] Please refer to Figure 1 The first embodiment of the utility model provides a vibration-damping magnetic module, including a housing 1, a first magnet 2 and a second magnet 3. The components of the embodiment are described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1 to Figure 2 As shown, an active chamber 10 may be provided inside the shell 1 , and a through hole 11 communicating with the active chamber 10 is formed through one or both ends of the shell 1 .

[0026] The first magnet 2 and the second magnet 3 can be movably installed in the movable chamber 10 of the shell 1 respectively. The first magnet 2 is located at the upper end of the movable chamber 10, and the second magnet 3 is located at the lower end of the movable chamber 10. The magnetism of the first magnet 2 is opposite to that of the second magnet 3, so that they can be parallel to each other through magnetic repulsion. A movable gap is provided between the first magnet 2 and the second magnet 3.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the shell 1 may include a first shell petal 15 and a second shell petal 16, which are combined to form an active chamber 10 for movably placing the first magnet 2 and the second magnet 3, and a cross-sectional portion of the first shell petal 15 is fixedly connected to a cross-sectional portion of the second shell petal 16.

[0028] The housing 1 can be assembled with the first magnet 2 and the second magnet 3 by fixedly connecting the first shell petal 15 and the second shell petal 16 in the longitudinal or transverse direction.

[0029] Specifically, the first shell petal 15 and the second shell petal 16 can be fixedly connected by gluing, hot-melt connection, screw locking or snap connection.

[0030] The housing 1 can be made of PET, PE, PS, ABS, PC, HIPS or other plastic materials, or non-magnetic metal materials. The housing 1 is preferably made of plastic material, and the material of the housing 1 is not limited to this embodiment.

[0031] like Figure 3 As shown, the housing 1 is sequentially formed with a first limiting ring portion 12 , a magnet accommodating portion 13 and a second limiting ring portion 14 from top to bottom. The first limiting ring portion 12 and the second limiting ring portion 14 are respectively formed and arranged at the upper and lower ends of the magnet accommodating portion 13 .

[0032] Furthermore, the first magnet 2 and the second magnet 3 can be respectively arranged parallel to each other in the magnet accommodating portion 13 through magnetic repulsion, and the top surface of the first magnet 2 abuts against the bottom surface of the first limiting ring portion 12 under the action of repulsion, and the top surface of the second magnet 3 abuts against the top surface of the second limiting ring portion 14 under the action of repulsion.

[0033] Preferably, the shape of the magnet receiving portion 13 matches the cross-sectional shape of the first magnet 2 and the second magnet 3 , and the shape of the housing 1 can be set to be square, cylindrical, triangular, polygonal or irregular.

[0034] Correspondingly, the first magnet 2 and the second magnet 3 are both horizontally placed inside the magnet accommodating portion 13, and the shapes of the first magnet 2 and the second magnet 3 can be set to square, circular, triangular, polygonal or irregular shapes. This embodiment does not limit the shapes of the shell 1, the first magnet 2 and the second magnet 3.

[0035] Preferably, the first magnet 2 and the second magnet 3 can be set to be a neodymium iron boron magnet, an iron chromium cobalt magnet, a ferrite magnet or an aluminum nickel cobalt magnet. Among them, the first magnet 2 and the second magnet 3 are preferably made of neodymium iron boron magnets, because neodymium iron boron magnets have high energy product and good stability, are suitable for the production of miniature permanent magnetic devices, and are widely used in the market.

[0036] In specific implementation, the smaller the magnetic gap between the first magnet 2 and the second magnet 3, the greater the magnetic field strength and the greater the resistance, and vice versa. When the magnetic module is vibrated by external force, the first magnet 2 and the second magnet 3 squeeze each other, which can generate a strong repulsive magnetic force and play a good vibration reduction and buffering role.

[0037] Embodiment 2

[0038] like Figure 6 and Figure 7 As shown, embodiment 2 of the utility model provides a vibration-damping bracket, including a bracket body 4 and at least two vibration-damping magnetic modules 5 of the above-mentioned embodiment 1. The bottom surface of the bracket body 4 can be provided with a plurality of connecting bosses 41, each connecting boss 41 extends from the through hole 11 of the corresponding vibration-damping magnetic module 5, and the bottom surface of each connecting boss 41 is fixedly connected to the top surface of the first magnet 2 of the corresponding vibration-damping magnetic module 5.

[0039] Of course, depending on the size of the external electronic product (such as audio), in other embodiments, the shape of the bracket body 4 can be adaptively adjusted according to the electronic product, and the number of vibration-damping magnetic modules 5 can also be appropriately increased or decreased to achieve vibration-damping and buffering effects on the bottom of the external electronic product. Among them, this second embodiment does not limit the shape of the bracket body 4 and the number of vibration-damping magnetic modules 5.

[0040] The vibration-damping magnetic module 5 in the second embodiment has the same structure as that in the first embodiment, and will not be described in detail herein.

[0041] To sum up, the vibration-damping magnetic module of the utility model has a compact structure and a reasonable design. The vibration-damping magnetic module can effectively reduce vibration and provide buffering when the vibration-damping magnetic module is vibrated by external force through the repulsive magnetic force generated by the first magnet and the second magnet. The overall volume of the vibration-damping magnetic module is small, which is convenient to carry and transport, has a wide range of applications, and is highly practical.

[0042] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
