Abstract: The disclosure provides a MEMS device. The MEMS device comprises a printed circuit board, a cover attached to the printed circuit board to form a housing, at least one sound hole formed in the housing, a transducer with a diaphragm inside the housing, and at least one shutter structure. Each shutter structure is mounted to the housing around a respective sound hole. Each shutter structure comprises a moveable component disposed near the inner surface of the housing, the moveable component remains at an open position under regular pressure such that an air flow path from the sound hole to the at least one ventilation hole of the substrate across the moveable component is opened, and moves to a first closed position under a high external pressure to block the at least one ventilation hole and close the air flow path.
