On the basis of this structure, in order to ensure the tightness between the microphone and the product casing, the waterproof membrane needs to be compressed. At this time, the strength of the waterproof membrane is relatively weak and prone to wrinkles, which affects the acoustic performance of the microphone. In order to avoid wrinkles on the waterproof membrane, the waterproof membrane cannot be compressed, which will affect the sealing performance of the microphone.
