Abstract:
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.
