Patent ID: 7443990

Claim:
A voltage biased capacitor circuit ( 30 ) for a loudspeaker, comprising: a. an amplifier ( 12 ′); b. at least one loudspeaker ( 14 ′); c. a pair of audio connectors ( 16 A′, 16 B′) electrically connected between the amplifier ( 12 ′) and the loudspeaker ( 14 ′) for transmitting an audio signal between the amplifier ( 12 ′) and the loudspeaker ( 14 ′); d. at least two audio circuit capacitors ( 32 A, 32 B) wired in series either on one of the audio connectors or between the audio connectors ( 16 A′, 16 B′); e. a direct current voltage source ( 34 ) wired in electrical communication with the audio circuit capacitors ( 32 A, 32 B) for transmitting through direct current voltage connectors ( 36 A, 36 B) a direct current to provide a bias voltage to the audio circuit capacitors ( 32 A, 32 B); and, f. at least one direct current resistor ( 37 ) secured between the audio circuit capacitors ( 32 A, 32 B) and the direct current voltage source ( 34 ), the resistor ( 37 ) having a resistance value sufficient to prevent dissipation of the audio signal from the audio connectors ( 16 A′, 16 B′) through the resistor ( 37 ) and direct current voltage connectors ( 36 A, 36 B).
