摘要:
A microphone has a movable diaphragm having a rest position, a stationary portion, and a set of springs movably coupling the diaphragm and the stationary portion. The diaphragm and stationary portion are spaced a first distance when the diaphragm is in the rest position. When not in the rest position, however, the diaphragm and stationary portion are capable of being spaced a second distance, which is greater than the first distance. Despite the change in distance, the diaphragm still is capable of returning the space from the second distance to the first distance when the diaphragm returns to the rest position.
