Abstract:
The present invention provides a MEMS microphone and an electronic equipment having the MEMS microphone. The electronic equipment of the present invention at least comprises: a MEMS microphone and a printed circuit board, wherein, the microphone comprises: a microphone chip containing acoustic and electric sensor, a package shell packaging the microphone chip, wherein, it is provided a sound hole on the package shell, the sound hole is positioned on the side of the microphone chip, it is also provided pins derived from the microphone chip on the side face of the package shell adjacent to the sound hole; the printed circuit board electrically connect with the pins of the MEMS microphone, which is used to output the electric signal generated by the microphone. The present invention avoids the sound air flow directly to the microphone chip, reduces dust interference on acoustic and electric sensor in microphone chip by means of changing the position of the sound hole of the microphone.
