Abstract

The energy storage and transmission capabilities of a capacitance-type electro-acoustical transducer are increased and the cost of producing such a transducer can be decreased by employing a thin, dielectric coating material (44) between the electrically conductive diaphragm (42) and backplate (48) of said transducer, and by locating the electrically conductive diaphragm support layer (40) on what would otherwise be an exposed outer diaphragm surface to protect same from physical as well as environmental damage.
