Abstract
A microphone system implements multiple microphones on a single base. To that end, the microphone system has a base, and a plurality of substantially independently movable diaphragms secured to the base. Each of the plurality of diaphragms forms a variable capacitance with the base and thus, each diaphragm effectively forms a generally independent, separate microphone with the base.
