An electrolytic loudspeaker assembly (10) designed to reproduce a broad band of audio signals and that consists of a thin, non-magnetic capacitive transducer (12) and a transducer driver unit (60). The transducer (12) consists of a vibratory center section (16) having on each surface a respective front section (26) and back section (32). Each section has an area that is less than 75 percent of the center section area and the entire compound diaphragm is held captive by a frame assembly (40). After the capacitive transducer (12) is completed, it is subjected to a one-time polarization and discharge cycle that provides the transducer with a permanent residual charge. The transducer (12) is driven and controlled by the transducer driver unit (60). The unit couples the audio signal to the transducer, supplies a regulated bias voltage and includes a dielectric drain circuit that maintains the proper ratio between the bias voltage and audio signal to achieve optimum performance. |
