Abstract
In a subcutaneous microphone used in medical devices, a structure is introduced that constrains the motion of the diaphragm during normal operation of the microphone. In one embodiment, a raised portion, such as a pole or pillar is placed in the chamber at the middle of the diaphragm. The raised portion may contact one or both of the bottom surface of the chamber and the underside of the membrane, and generally acts to reduce the amount of deflection experienced by the membrane.
