Abstract

본 발명은 입력된 음성신호를 증폭하여 발생하는 음성발생장치에 관한 것이다.The present invention relates to a voice generating device that is generated by amplifying an input voice signal.

음성소스로부터 음성신호를 수신하여 증폭하는 음성신호수신부(1)와, 상기 음성신호수신부(1)에서 출력되는 신호를 증폭하여 음성신호파를 발생하는 음성신호발생부(11)와, 상기 음성신호발생부(11)에 입력되는 음성신호의 레벨을 자동으로 조절하는 자동음량조절부(21)로 구성된다.A voice signal receiver 1 for receiving and amplifying a voice signal from a voice source, a voice signal generator 11 for amplifying a signal output from the voice signal receiver 1 to generate a voice signal wave, and the voice signal It is composed of an automatic volume control unit 21 for automatically adjusting the level of the voice signal input to the generator (11).

이렇게 함으로써, 음량조절레벨을 자동으로 조정할 수 있게 된다.By doing this, the volume control level can be automatically adjusted.
