ABSTRACT:
A miniature microphone, comprising a diaphragm, supported for displacement in response to acoustic waves, from which a plurality of projections extend; a plurality of projections extending from a surface; a body, supporting the surface to maintain the plurality of projections from the diaphragm and the plurality of projections from the surface in close proximity; and an electromagnetic sensor adapted to sense an electromagnetic interaction between the plurality of projections from the diaphragm and the plurality of projections from the surface and produce an electrical signal in response thereto. The interaction may be detected substantially without inducing a force which tends to substantially displace the diaphragm, since the electrostatic force is substantially parallel to the diaphragm surface.
