Among them, as a high-frequency device used in the car, the quality of the speaker directly affects the user's usage experience and driving experience. For the problem of dust accumulation in the speaker mask, the traditional solution is to add a layer of non-woven fabric between the speaker and the mask. However, with this method, as time accumulates, the pores of the non-woven fabric will be filled with dust, which seriously affects the sound transmission effect of the speaker and reduces the user's direct perception of the speaker sound quality. Secondly, the use of non-woven fabric is relatively cumbersome for subsequent cleaning. One is the method of disassembling and assembling the non-woven fabric, and the other is the problem of cleaning the non-woven fabric, which brings great inconvenience to users.
