Abstract

본 발명은 전화 통화시 가전기기의 오디오 출력을 제어하는 회로에 관한 것으로, 일반적으로 거실등의 한 공간에 티브이, 오디오세트, 브이씨알 등 오디오 출력이 있는 가전기기와 전화기를 함께 설치하는데, 이에 따라 가전기기의 오디오 출력이 있을 때 전화가 걸려오거나 전화통화를 하고자 하면 원활한 전화통화를 위해 오디오 출력을 줄이거나 아예 파워를 오프시킨 후 전화통화를 하였다. 본 발명은 전화벨이 울리거나 수화기를 들게되면 티브이 등의 오디오 출력은 일정레벨이하로 줄이고, 브이씨알은 일시정지 모드로 제어한 후 통화가 끝나 수화기를 내려 놓으면 원래대로 복귀되게 하고, 여러사람의 사용중을 대비하여 사용자에 의해 상기와 같은 오디오 출력 제어를 자동으로 하는 모드와 제어하지 않는 노어말 모드를 선택할 수 있게하여 사용상의 편리함을 주기 위한 것이다.The present invention relates to a circuit for controlling an audio output of a home appliance during a telephone call, and generally installs a home appliance and a telephone having an audio output such as a TV, an audio set, and a V-C in a space such as a living room. When there is an audio output of a home appliance, if a call is made or a telephone call is made, the audio output is reduced or the power is turned off altogether for a smooth phone call. The present invention reduces the audio output of the TV, such as a TV ringing or picking up the handset to a certain level or less, V-Cal to control the pause mode and then return to its original state when the phone hangs down and hangs up. In order to provide convenience in use by allowing the user to select a mode for automatically controlling the audio output as described above and a normal mode without control.
