Abstract

본 발명은 증폭기의 과열 및 장시간 사용으로 인해 증폭기나 스피커가 파손되는 것을 방지시키기 위한 것으로, 스피커를 구동시키는 증폭기의 온도를 감지하는 감지부와, 상기 감지부의 온도 변화에 따른 신호를 인가받는 마이콤과, 상기 마이콤의 출력신호에 의해 출력 음량 레벨을 감소시키는 출력레벨 감소부로 구성되며, 증폭기 출력단의 온도를 감지하는 단계와, 일정 온도 이상의 온도가 감지될 때 그 신호를 받아들이는 단계와, 증폭기의 온도 변화에 따른 신호를 순차적으로 출력하는 단계와, 상기 출력에 의해 출력 레벨을 일정한 레벨로 감소시키는 단계로 이루어짐을 특징으로 하는 오디오 출력 음량 제어 장치 및 그 방법이다.The present invention is to prevent the amplifier or speaker from being damaged due to overheating and long-term use of the amplifier, the sensing unit for sensing the temperature of the amplifier for driving the speaker, the microcomputer receiving a signal according to the temperature change of the sensing unit; And an output level reduction unit for reducing an output volume level by the output signal of the microcomputer, sensing the temperature of the amplifier output stage, receiving the signal when a temperature above a predetermined temperature is detected, and the temperature of the amplifier. And a method of sequentially outputting a signal according to a change, and decreasing the output level to a constant level by the output.
