Abstract:
A MEMS microphone. The MEMS microphone includes a membrane, a spring, and a first layer having a backplate, and a first OTS structure. The spring has a first end coupled to the membrane, and a second end mounted to a support. The first OTS structure is released from the backplate and coupled to a structure other than the backplate, and is configured to stop movement of the membrane in a first direction after the membrane has moved a predetermined distance.
