Abstract
The utility model relates to a microphone module, which comprises a microphone unit and a suite for packing and fixing the microphone unit. A sound aperture is formed on the microphone unit, a sound inputting part corresponding to the sound aperture on the microphone unit is arranged on the suite. The sound inputting part adopts a cavity structure, and is composed of sidewalls and a bottom wall with a certain angle to the sidewalls, and a filling part for filling between the sidewalls and the bottom wall is arranged inside the sound inputting part. Because the filling part is arranged inside the suite, the microphone module provided by the utility model reduces the internal space of the sound inputting part, thus reducing the resonance and improving the acoustic characteristic and sensitivity of the product.
