Abstract

본 발명은 다중방송 동시 청취장치에 관한 것으로, 종래의 오디오 시스템은 단일방송 또는 테이프나 CD메카니즘중 어느 하나만 선택하여 청취할 수 있도록 구성되어 있어, 2인 이상이 하나의 오디오 시스템을 이용하여 소정의 방송국을 청취하고자할시 서로의 취향이 상호 일치되지 않아 의견 충돌등이 발생될 우려가 있어, 본 발명에서는 기존의 오디오 시스템에 2개의 FM/AM 튜닝부(1,2) 및 PLL부(3,4)등을 부가시키되 기능키 입력부(6)에는 다중모드 선택키를 부가시켜 한 사람의 사용자가 FM/AM, 테이프 및 CD 중 소정의 음향신호등을 청취하고 있는 도중, 주변의 다른 사람은 현재 청취중인 내용과 또 다른 방송신호를 선택하여 청취할 수 있도록 하므로서 다양한 오디오 소오스를 동일한 시스템에서 동시에 청취할 수 있어 제품의 신뢰도를 대폭 향상시킬 수 있는 것이다.The present invention relates to a multi-broadcasting simultaneous listening apparatus, and the conventional audio system is configured to listen to either a single broadcast or a tape or CD mechanism, so that two or more persons use a single audio system. When listening to a broadcasting station, there is a possibility that disagreement or the like may occur due to mutual disagreement with each other. In the present invention, two FM / AM tuning units 1 and 2 and a PLL unit 3, 4) Add a multi-mode selection key to the function key input unit 6 so that one person is listening to a predetermined sound signal among FM / AM, tape, and CD, while others are currently listening. By selecting and listening to another broadcast signal, you can listen to various audio sources simultaneously on the same system, which can greatly improve the reliability of the product. It is.
