Abstract

본 발명은 오디오 스피커의 무선원격 제어장치에 관한 것으로 오디오 시스템의 본체 내에서 발생하는 음신호를 본체 송신기를 통하여 변조시켜 안테나로 송신하면, 근원거리에 설치된 다수개 스피커 장치의 수신기에서 신호를 수신하여 복조하고 스피커를 통하여 증폭된 가청음을 들을 수 있는 것이다.The present invention relates to a wireless remote control apparatus for an audio speaker. When a sound signal generated in a main body of an audio system is modulated through a main body transmitter and transmitted to an antenna, the signal is received by a receiver of a plurality of speaker devices installed at a far distance. You can demodulate and hear the amplified audible sound through the speakers.

즉, 오디오 본체로 부터의 음신호를 주파수 변조나 진폭변조를 거쳐 송신안테나로 송신하며, 스피커의 수신기에서 수신하여 신호를 증폭, 검파, 복조 및 저주파 전압증폭을 거쳐 스피커의 앰프로 가청음을 출력하게 회로를 구성하여 일정한 장소 및 위치에서 다수의 청취자에게 본체의 음을 청취할 수 있는 것이다.That is, the sound signal from the audio main body is transmitted to the transmission antenna through frequency modulation or amplitude modulation, and received by the receiver receiver to amplify, detect, demodulate, and low frequency voltage amplification to output the audible sound to the speaker amplifier. By constructing a circuit, a plurality of listeners can hear the sound of the main body at a predetermined place and location.
