ABSTRACT:
An electrostatic transducer, such as a loudspeaker, employs parallel plastic diaphragms, each carrying an electrically conductive metallic layer; frames separately mounting the diaphragms, the frames assembled to a central, perforate electrically conductive sheet sandwiched between the diaphragms, and to foraminous sheets of dielectric material sandwiched between the central sheet and the diaphragms and frames, thereby to realize a compact, easily assembled unit characterized by very high performance qualities.
