[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment: a car speaker sealing ring with good sealing effect includes a speaker body 1, a connecting block 2 fixedly connected to the inner wall of the speaker body 1, and a sealing component 3 movably connected to the surface of the connecting block 2;

[0024] The sealing assembly 3 includes a first lip 31 that is movably connected to the surface of the connecting block 2. The bottom end of the first lip 31 is fixedly connected to a sealing ring body 33, which ensures that the buffer ring 37 buffers the vibration energy of the sealing ring body 33 when the car is running. The elastic support ring 34 provides elasticity so that the first lip 31 and the second lip 32 are always tightly fitted with the mounting surface of the speaker body 1, ensuring the sealing effect of the sealing ring body 33.

[0025] In this embodiment, the sealing assembly 3 further includes a second lip 32. The top end of the sealing ring body 33 is fixedly connected to the second lip 32. An elastic support ring 34 is fixedly connected inside the sealing ring body 33. A connecting spring 35 is fixedly connected to one side of the sealing ring body 33. A fixing block 36 is fixedly connected to one end of the connecting spring 35. A buffer ring 37 is contacted and connected to one end of the fixing block 36. By setting the sealing assembly 3, the buffer ring 37 is guaranteed to buffer the vibration energy received by the sealing ring body 33. The elastic support ring 34 provides elasticity so that the first lip 31 and the second lip 32 are always tightly fitted with the mounting surface of the speaker body 1, thus ensuring the sealing effect of the sealing ring body 33.

[0026] The inner material of the sealing ring 33 is made of hydrogenated nitrile rubber, and the outer material of the sealing ring 33 is made of silicone rubber. This ensures that the inner layer of the sealing ring 33 has oil resistance, heat resistance and sealing performance, while the outer sealing ring 33 plays a protective and auxiliary sealing role, thus ensuring the service life of the sealing ring 33.

[0027] The first lip 31 and the second lip 32 are located at the same center. The diameter of the first lip 31 is larger than the diameter of the second lip 32, which ensures that when the first lip 31 and the second lip 32 are connected to the speaker body 1, multiple sealing barriers are formed, effectively preventing dust, moisture and other impurities from entering the speaker body 1.

[0028] A snap-fit ​​groove adapted to the size of the buffer ring 37 is provided on one side of the sealing ring body 33. The buffer ring 37 is snapped into the sealing ring body 33 through the snap-fit ​​groove, which ensures that the buffer ring 37 slides inside the snap-fit ​​groove to absorb the vibration energy of the vehicle driving by compressing the connecting spring 35. At the same time, the buffer ring 37 slides on the inner wall of the snap-fit ​​groove to absorb the rebound energy of the connecting spring 35, thus ensuring the buffering effect of the vehicle vibration energy.

[0029] The sealing ring 33, the elastic support ring 34, and the buffer ring 37 are all located on the same vertical line. The diameter of the buffer ring 37 is larger than the diameter of the sealing ring 33, and the diameter of the sealing ring 33 is larger than the diameter of the elastic support ring 34. This ensures that the buffer ring 37 can fully buffer the vibration energy of the vehicle around the sealing ring 33. At the same time, the elastic support ring 34 provides elasticity to keep the first lip 31 and the second lip 32 in close contact with the mounting surface of the speaker body 1.

[0030] There are five sets of connecting springs 35, all located at the same center. The connecting springs 35 are distributed at equal angles on one side of the sealing ring body 33, ensuring that the buffer ring 37 pushes the five sets of connecting springs 35 to compress and quickly transmit the vibration energy of the vehicle.

[0031] The working principle and usage process of this utility model: This utility model is a car speaker sealing ring with good sealing effect. When it is necessary to ensure the sealing quality of the sealing ring during car operation, the inner and outer surfaces of the sealing ring body 33 are made of hydrogenated nitrile rubber and silicone rubber materials. This ensures that the inner layer of the sealing ring body 33 has oil resistance, heat resistance and sealing performance, while the outer sealing ring body 33 plays a protective and auxiliary sealing role. At the same time, the buffer ring 37 effectively buffers the vibration and impact force during car operation, and the elastic support ring 34 provides uniform radial pressure to the sealing ring body 33 through elastic force, ensuring that the first lip 31 and the second lip 32 are always tightly fitted with the mounting surface, ensuring the tightness of the connection between the sealing ring body 33 and the inner wall of the speaker body 1, and ensuring the sealing effect and service life of the sealing ring body 33.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
