Abstract

An MEMS microphone, including a base having a back cavity, and a capacitor system fixedly supported on the base, the capacitor system including a diaphragm and a back-plate spaced from the diaphragm. The diaphragm is provided with a venting portion passing through an edge thereof, and the base includes an inner side surface surrounding the back cavity and at least one venting groove formed by recessing from an inner side surface in a direction away from the back cavity direction. The at least one venting groove is disposed corresponding to the venting portion and is in communication with the venting portion and the back cavity, respectively. The base is provided with a venting groove, so that the back cavity has larger space for venting, and the airflow can easily pass through, thereby reducing the probability of breaking the diaphragm. Thus, the MEMS microphone can have a higher reliability.
