The vibrations produced not only affect the sound quality, but also affect the service life of the product.

[0003] In order to avoid or reduce the vibration generated when the speaker is working, various methods are adopted in the prior art, such as setting a suction cup or applying rubber paint at the bottom of the speaker, or setting a single rubber buffer in the speaker, or setting a shock-absorbing spring to damp the speaker, etc. However, the disadvantage of such methods is that the shock-absorbing effect of the suction cup, the rubber paint or the single rubber buffer will gradually decrease after the speaker is used for a long time, and the stability of the shock-absorbing performance of the speaker is poor. Therefore, based on the above-mentioned defects, the applicant has proposed a better technical solution to solve the above-mentioned technical problems.

The buffer assembly 33 is between the two fastening bolts 32. The material of the rubber buffer block 31 can be made of commonly used shock-absorbing and noise-reducing materials on the market, such as polyurethane.

[0025] The two fastening bolts 32 in the shock absorbing mechanism 3 of the utility model are respectively connected to the loudspeaker 2 and the mounting groove 12 to fix the loudspeaker 2 in the mounting groove 12, and the shock absorbing mechanism 3 adopts a structural setting between a rubber buffer block 31 and a buffer component 33. On the one hand, the shock absorbing effect of the rubber buffer block 31 itself is utilized to reduce the vibration generated when the loudspeaker 2 is working. On the other hand, when the vibration squeezes the rubber buffer block 31, the buffer component 33 arranged therein can further reduce the vibration and eliminate noise generated by the loudspeaker 2. The two play a technical role of double shock absorption to improve the shock absorption effect and stability performance of the structure.

[0026] In this embodiment, the buffer assembly 33 includes a hydraulic damper 331 and a shock-absorbing spring 332. The two ends of the hydraulic damper 331 are respectively connected to two fastening bolts 32, and the shock-absorbing spring 332 is arranged outside the hydraulic damper 331. The configuration of the hydraulic damper 331 and the shock-absorbing spring 332 can increase the elastic performance of the buffer assembly 33, enhance its shock-absorbing performance, and support the rubber buffer block 31 for a long time to improve its deformation resistance and shock-absorbing effect.

[0028] A sealing gasket 5 is provided on the outer edge of the fixing plate 21 ; the sealing gasket 5 closes the gap between the fixing plate 21 and the mounting groove to ensure the sealing performance of the sound box 1 ; at the same time, its soft structure can appropriately reduce vibration and noise of the speaker 2 .

[0029] In this embodiment, elastic gaskets 6 are provided between the fixing plate 21 and the rubber buffer block 31, and between the rubber buffer block 31 and the mounting groove 12; the elastic gaskets 6 serve to improve the stability of the speaker 2 during installation, and avoid affecting the durability of the speaker 1 due to loose fixation.

[0030] The mounting groove 12 is provided with a threaded hole 121 matching the fastening bolt 32; when installing the shock absorbing mechanism 3, it can be first installed and connected with the threaded hole 121 of the mounting groove 12 through the fastening bolt 32, and then connected with the fixing plate 21 through another fastening bolt 32 and the fastening nut 4.

It is arranged on the outer surface of the rubber buffer block 31 to further improve its buffering performance and resistance to deformation.

[0032] The working principle of this utility model:

On the other hand, when the vibration squeezes the rubber buffer block 31, the buffer component 33 arranged therein can further reduce the vibration and eliminate noise generated by the speaker 2. The two play a technical role of double shock absorption to improve the shock-absorbing effect and stability performance of the structure.
