Zusammenfassung:A power supply assembly ( 10 ) specifically designed to supply a bias voltage to a diaphragm ( 34 ) located on an electrolytic or electrostatic speaker(s)( 32 ). The assembly ( 10 ) produces the bias voltage from an audio signal derived from an audio amplifier ( 30 ). Thus, a direct connection to a utility power source is not required. The assembly ( 10 ) is comprised of five major circuits: a rectifier and filter circuit ( 12 ) which converts the input audio signal to a regulated d-c current, an adjustable regulator circuit ( 14 ) which is applied the regulated d-c current and produces a regulated direct-current voltage, a d-c to a-c inverter circuit ( 16 ) which receives the regulated d-c voltage and produces a high voltage a-c, an eight-times multiplier and rectifier circuit ( 18 ) which receives the high-voltage a-c and produces a regulated high voltage d-c, and a current limiter circuit ( 20 ) which receives the regulated high voltage d-c and produces the bias voltage which biases the diaphragm ( 34 ).
