Abstract

본 발명은 전화선에 나타나는 전압이 대기시와 통화시에 다른점을 이용하여 전화통화시에 텔레비전의 음성출력이 자동으로 뮤트되도록 한 텔레비전의 음성출력 뮤트장치에 관한 것으로, 전압노이즈에 의한 오동작을 방지하기 위한 필터부(1)와, 전화선의 전압을 분압하기 위한 분압회로(2), 상기 분압회로(2)의 전압레벨에 따라 스위칭되는 스위칭부(3), 방송신호를 선국하기 위한 튜너(4), 상기튜너(4)에서 선국된 방송신호에서 음성의 중간주파신호를 검출하는 음성중간주파회로(5), 상기 음성중간주파회로(5)의 음성의 중간주파신호를 근거로 음량, 음색등을 조정하는 음성처리부(6), 상기 음성처리부(6)의 음성신호를 증폭하는 한편 상기 스위칭부 (3)의 스위칭에 따라 음성출력을 뮤트하는 음성출력부(7)를 포함하여 구성된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound output muting device of a television, in which a sound output of a television is automatically muted at a telephone call by using a difference between a voltage appearing at a telephone line and a standby state. A filter unit 1 for adjusting, a voltage divider circuit 2 for dividing a voltage of a telephone line, a switching unit 3 switched according to the voltage level of the voltage divider circuit 2, and a tuner 4 for tuning a broadcast signal. ), A voice intermediate frequency circuit 5 for detecting an intermediate frequency signal of speech from the broadcast signal tuned by the tuner 4, a volume, a tone, etc. on the basis of the intermediate frequency signal of the speech of the speech intermediate frequency circuit 5; And a voice output unit 7 for amplifying the voice signal of the voice processor 6 and muting the voice output according to the switching of the switching unit 3.
