Since the pores of the waterproof membrane 2012 are small, it is also dustproof. effect. In one embodiment, the waterproof membrane 2012 can be made of polytetrafluoroethylene.

Referring to FIGS. 1 to 7 , in some embodiments of the present invention, the baffle 100 is disposed on the backside of the waterproof membrane 2012 of the audio component 200 and is used to support the waterproof membrane 2012 , and the baffle 100 includes a fixed The fixing part 10 and the supporting part 20 elastically connected to the fixing part 10, the fixing part 10 is fixedly connected to the audio component 200, at least part of the supporting part 20 is disposed facing the waterproof membrane 2012, the baffle 100 is further provided with a vent hole 22, and the relationship between the area S1 of the vent hole 22 and the area S2 of the baffle 100 is: 1/7≤S1/S2≤1/3.

It can be understood that, the baffle 100 can be formed by setting a mold, injecting the injection material into the mold, or forming by vapor deposition etching, or by punching a stamping part. The baffle 100 can be made of metal (the material of the metal can be stainless steel, aluminum, aluminum alloy, copper, copper alloy, iron, iron alloy, etc.), plastic (the plastic can be selected such as ABS , POM, PS, PMMA, PC, PET, PBT, PPO, etc.), resin materials, fiber materials, etc. Alternatively, a mixture of any of the foregoing materials may be used, as long as the baffle 100 can be well fabricated and the structure of the baffle 100 is guaranteed to be stable. In this way, it is more beneficial to improve the stability of the arrangement of the baffle 100 , thereby effectively improving the practicability, reliability, and durability of the baffle 100 .

The sound pickup hole may be a circular hole or a polygonal hole, as long as it is convenient for the chip inside the microphone to receive external information passing through the sound pickup hole.

It should be noted that, after the waterproof membrane 2012 is fixed with the audio component 200, the connection of the waterproof membrane 2012 will not enter water. Therefore, one side of the waterproof membrane 2012 will be in contact with water, and the other side will not be in contact with water (this side is the for the backwater side).

When the relationship between the area S1 of the ventilation hole 22 and the area S2 of the baffle 100 is that S1/S2 is less than 1/7, the area of the ventilation hole 22 will be smaller, and external information (including sound wave information, vibration information, etc.) When passing through the baffle 100 , the lightness will be greatly weakened, thereby reducing the external information collection effect of the audio component 200 and affecting the stability of use.

Since the supporting portion 20 is elastically connected with the fixing portion 10 , the supporting portion 20 can be deformed relative to the fixing portion 10 to a certain extent so as to fit the waterproof membrane 2012 . The depression reduces the area where the waterproof membrane 2012 is attached to the baffle 100 , and reduces the probability of film suction. After the water pressure is over, the support portion 20 returns to the state when it is not elastically deformed, and then pushes the waterproof membrane 2012 In this way, the recovery efficiency of the waterproof membrane 2012 is further improved. In this way, the technical solution of the present invention can enable the baffle 100 to support the waterproof membrane 2012 well, ensure the normal operation of the waterproof membrane 2012 , and then improve the use stability of the audio component 200 .
