Abstract

본 발명은 노래반주기기의 마이크 합성장치에 관한 것으로, 특히 마이크로 입력되는 입력신호크기를 조절하지 않고 마이크로 입력되는 사용자의 음성이 배경음에 묻히지 않도록 자동으로 조절할 수 있도록 한 것이다.The present invention relates to a microphone synthesizing apparatus for a karaoke machine, and in particular, to automatically adjust so that the user's voice is not buried in the background sound without adjusting the size of the input signal input to the microphone.

종래 노래반주기기의 마이크 합성장치는 씨디, 씨디지 및 비디오 씨디에서 재생되여 신호출력부에서 출력되는 배경음의 신호가 너무 크면 마이크를 통하여 입력되는 사용자의 음성신호가 상대적으로 작게되므로, 입력레벨 조정부에서 사용자의 음성신호의 레벨조정을 크게 해야 한다. 그러나 상기와 같이 레벨조정을 크게한다면 마이크를 통하여 과도한 입력이 들어올때도 있기 때문에 앰프부와 스피커를 파손시킬 수도 있으며, 또한 반대로 배경음이 작게되면 마이크를 통하여 입력되는 사용자의 음성신호의 레벨도 줄여주어야 하게 되는 문제점이 있었다.The microphone synthesizer of the conventional vocal repeater is reproduced from the CD, CD and video CD, so if the signal of the background sound output from the signal output is too large, the user's voice signal input through the microphone is relatively small, so Adjust the level of the user's voice signal. However, if the level is increased as described above, excessive input may be caused through the microphone, which may damage the amplifier and the speaker. On the contrary, when the background sound is low, the level of the user's voice signal input through the microphone should be reduced. There was a problem.

본 발명은 이와같은 문제점을 해결하기 위하여 마이크에서 출력되는 사용자의 음성신호의 레벨과 배경음의 신호레벨을 검출하여 배경음신호와 사용자의 음성신호의 균형을 자동으로 맞추어 주고, 또한 마이크의 신호입력에 제한회로를 구성하여 과도한 신호가 입력되지 않도록 하여, 마이크를 통하여 입력되는 입력신호의 크기를 조정하지 않고도 마이크로 입력되는 사용자의 음성이 배경음에 묻히지 않도록 배경음의 크기를 자동으로 조정할 수 있도록 한 것으로 노래반주기능을 갖춘 오디오기기등에 적용한다.The present invention detects the level of the user's voice signal and the background sound signal output from the microphone to automatically balance the background sound signal and the user's voice signal to solve this problem, and also limits the signal input of the microphone By configuring a circuit to prevent excessive signal input, the song accompaniment function can automatically adjust the background sound so that the user's voice input into the microphone is not buried in the background sound without adjusting the size of the input signal input through the microphone.
