ABSTRACT:
An improved 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 compound diaphragm (14) further consisting of a vibratory center section (16) having attached to each of its surfaces a respective front section (26) and back section (32). All three sections of the compound diaphragm are held captive by a frame assembly (40). The transducer (12) is driven and controlled by the transducer driver unit (60). The unit couples the audio signal to the transducer's front and back sections (26) (32) and supplies an unregulated, d-c bias voltage to the transducer's center section (16). The unit (60) maintains the proper ratio between the bias voltage and audio signal to achieve optimum performance.
