Power saving system and method for loudspeaker
A power saving system includes a sensor, a processor, a timer, and a switch. The sensor senses movements in the diaphragm of the loudspeaker. The processor determines whether the loudspeaker is power-on and in use or power-on but not in use. The processor further determines whether a preset period of time has elapsed since the indication of power-on but not in use was first given. If the preset period of time has elapsed, the processor further controls the switch to disconnect the power source from the loudspeaker.
