First Claim
Patent Images
1. A powered speaker comprising:
- a speaker body;
an electrical relay that is selectively actuated based on the power status of an audio source unit, the relay being located within the speaker body and having an actuation circuit an actuation input in electrical communication with the actuation circuit, wherein the actuation input is connectable to an output power-line from the audio source unit, the actuation circuit being energized when the audio source unit is turned on and de-energized when the audio source unit is turned off;
a manual switch that selectively opens and closes the electrical relay;
a continuous power input in electrical communication with an amplifier circuit, wherein the electrical relay selectively opens and closes the amplifier circuit based on the ON/OFF power status of the audio source unit, the electrical relay being energized when the audio source unit is turned ON and de-energized when the audio source unit is turned OFF; and
an integral audio transducer in electrical communication with the amplifier circuit.

Abstract
The present invention provides a powered speaker, such as a subwoofer that may be turned on and off remotely by energizing the auxiliary AC power supply provided with an audio device or other source unit. The main power of the powered subwoofer is provided via a wall outlet or suitable power supply that may adequately supply the necessary power.

10. A powered speaker comprising:
-
an integral relay for turning the powered speaker on and off by selectively actuating based on the ON/OFF power status of an audio source unit, the relay being energized when the audio source unit is turned ON and de-energized when the audio source unit is turned OFF; said integral relay device having an output and an input; said output provides a device power needed to energize the speaker when the relay is actuated via the relay output; said input provides the actuation power to actuate the relay; and said actuation power is provided via an auxiliary power output from an audio source unit, the auxiliary power output being either a 120 V output or a 12 V output. - View Dependent Claims (11, 12, 13, 14)

15. A powered speaker comprising:
-
a speaker body; an electrical relay that is selectively actuated based on an audio source unit power status, the relay being located within the speaker body and having an actuation circuit; an actuation input in electrical communication with the actuation circuit, wherein the actuation input is connectable to an output power-line from the audio source unit, the power-line being either a 12 V power-line or a 110 V power-line; a manual switch that selectively opens and closes the actuation circuit; and a continuous power input in electrical communication with an amplifier circuit, wherein the electrical relay selectively opens and closes the amplifier circuit based on the ON/OFF power status of the audio source unit, the electrical relay being energized when the audio source unit is turned ON and de-energized when the audio source unit is turned OFF, the power signal being a 12 V power signal or a 110 V power signal, the power signal being received through the actuation input.
