Abstract

본 발명은 음향기기에 관한 것으로, 음향기기의 최종 증폭단에 인가되는 음원신호를 시분할하여 CD(Compact Disk)의 청취, 테크(Deck)를 통한 테이프의 재생, 튜너(Tunner)를 통한 방송수신 및 VCR 데크를 통한 영화감상등의 기능이 독립적으로 수행될 수 있도록 하여 다수의 사용자가 원하는 각각의 기능을 하나의 음향기기로부터 동시에 청취 및 감상할 수 있도록 한 것이다.The present invention relates to an audio device, which time-divides a sound source signal applied to the final amplifier stage of the audio device, listens to a compact disc, plays a tape through a deck, receives a broadcast through a tuner, and a VCR. Functions such as watching movies through the deck can be performed independently so that multiple users can simultaneously listen to and listen to each desired function from a single audio device.

본 발명은 음향기기의 메인앰프를 다수의 사용자에게 할당되도록 구비한 후 다수의 사용자로부터 인가되는 선택신호에 따라 각각의 재생장치로부터 인가되는 음원신호를 각각의 프리앰프에 할당된 소정의 주파수 주기로 샘플링하며 샘플링된 음원신호를 소정의 타임슬롯으로 시분할하여 증폭한 후, 역 변조를 통해 원래의 음원신호로 복원하여 각각의 사용자에게 독립적으로 출력함으로써 하나의 음향기기를 통하여 다수의 사용자가 독립된 음원 및 영상을 감상할 수 있다.According to the present invention, a main amplifier of an audio device is assigned to a plurality of users, and then, according to a selection signal applied from a plurality of users, a sound source signal applied from each playback device is sampled at a predetermined frequency period assigned to each preamplifier. Time-divided and amplified the sampled sound source signal into a predetermined time slot, and then restored to the original sound source signal through inverse modulation, and outputs to each user independently. You can appreciate it.
