Abstract

본 발명은 리모콘에 의한 오디오의 원격제어에 관한 거으로, 일반적으로 사용되고 있는 오디오 시스템은 스피커가 본체와 분리되어 있는 공간에 있을 경우 본체를 제어할 수 없을 뿐만 아니라 임피던스 매칭의 관계로 인하여 복수 조의 스피커를 동시에 동작시킬 수 없는 문제점을 가지고 있다.The present invention relates to remote control of audio by a remote control. In general, an audio system generally used cannot control the main body when the speaker is in a space separated from the main body, and a plurality of sets of speakers due to impedance matching. Has a problem that can not be operated at the same time.

이에 따라 본 발명의 목적은 상기와 같은 기존의 오디오 시스템에 따르는 결함을 해결하기 위하여, 본체와 분리된 공간에 있는 스피커에 리모콘 수신부를 두고 분리된 공간에서 리모콘으로 본체를 직접 제어하도록 함과 아울러 복수 조의 스피커를 동시에 구동할 때에는 자동으로 임피던스 매칭이 이루어질 수 있게 하는 오디오 시스템 원격 제어회로를 제공하는데 있다.Accordingly, an object of the present invention is to provide a remote control receiver in a speaker in a space separated from the main body to directly control the main body with a remote control in a separate space in order to solve the deficiencies according to the existing audio system as described above. It is to provide an audio system remote control circuit that allows impedance matching to be automatically performed when driving a pair of speakers simultaneously.
