ABSTRACT:
A capacitive transducer includes a plurality of first electrodes which, together with at least one second electrode, define a plurality of capacitors having capacitance variable with spacing. An actuator element connected to a plate supporting at least one second electrode angularly deflects the plate. This angular deflection causes the spacing, and thus the capacitance, of electrode sets disposed on opposite sides of the center of the plate to vary in a differential manner.
