ABSTRACT:
An electrostatic transducer in which a plurality of stretched diaphragm sections are electrostatically charged and an electrical field exerts an electromagnetic force on the diaphragm sections. The electric field varies in response to variations in an input signal to cause responsive movement of the diaphragm sections. Each of said diaphragm sections is constructed and arranged to have a resonant frequency that differs from that of the other diaphragm sections.
