Abstract

An output protecting device for sound playing system, in which the system consists of CPU, one memory, one sound source device, one liquid display driver, one amplifier, comprises one low voltage detecting unit coupled to the amplifier. When over-low voltage is detected, the system sends control signal in real time, turning off amplifier to protect system.
