| titleOfInvention | Mems microphone |
| abstract | The utility model provides a MEMS microphone, including shell and circuit board, the fixed packaging structure who forms MEMS of shell and gate board is provided with the sound hole of receiving external voice signal on the shell, the sound hole is in the shell surface is projected to be accounted for than being 0.1% to 3%. Utilize the utility model discloses, can the too big or undersize in solution sound hole, influence its acoustic performance's problem to guarantee the regular transmission of MEMS microphone's voice signal and good acoustic performance. |
