Abstract

본 발명은 오디오 신호 뮤트(mute) 장치 및 방법에 관한 것으로, 전화라인을 통하여 전화기(40)로 전송되는 신호를 검출하기 위한 신호 검출부(50)와, 신호 검출부(50)에서 검출된 신호에 따라 오디오 신호 뮤트 및 이를 디스플레이 하기 위한 제어 신호를 발생하는 마이컴(60)과, 마이컴(60)에서 발생된 제어신호에 따라 오디오 신호를 뮤트하는 음성 신호처리부(70)와, 마이컴(60)의 제어에 따라 오디오 신호 뮤트 상태임을 디스플레이하는 디스플레이부(80)를 포함하고 구성되어, 전화라인(L)을 통하여 전송되는 링 신호 및 음성 신호를 검출하여 오디오 신호를 자동으로 뮤트시키고 뮤트 상태임을 디스플레이할 수 있을 뿐만 아니라, 필요시에는 수동으로도 오디오 신호의 뮤트 및 해제를 실행할 수 있도록 한 것이다.The present invention relates to an audio signal mute apparatus and method, and includes a signal detector 50 for detecting a signal transmitted to the telephone 40 through a telephone line and a signal detected by the signal detector 50. The microcomputer 60 generates the audio signal mute and a control signal for displaying the same, the audio signal processor 70 mutes the audio signal according to the control signal generated from the microcomputer 60, and the microcomputer 60 controls the microcomputer 60. The display unit 80 is configured to display an audio signal mute state, and detects a ring signal and a voice signal transmitted through the telephone line L, thereby automatically muting the audio signal and displaying a mute state. In addition, when necessary, the audio signal can be muted and released manually.
