Abstract

본 발명은 카오디오를 구성하는 라디오 및 콤팩트디스크 등을 청취할 때 음량을 조절하는 전자볼륨에 있어서, 상기 전자볼륨의 동작시 가변음량을 조절하여 신속하게 원하는 음량으로 미세조정이 가능한 카오디오의 전자 볼륨 미세조정장치에 관한 것으로, 카오디오의 음량을 조절할 때에는 마이컴에서 출력되는 음성신호를 감지하여 설정된 값과 비교판단하여 스피커에 인가되는 음성신호가 설정된 기준값과 차이가 크게 되면 전자볼륨단자에 의해 변화하는 음량의 변화폭이 크게 되고, 기준값과 스피커에 인가되는 음성신호의 차이가 작게 되면 전자볼륨단자에 의해 변화하는 음성신호의 변화폭이 작게되어 사용자가 원하는 음량에 신속하게 도달하면서 동시에 미세조정에 의한 정확한 음량에 도달하게 되는 효과가 있다.The present invention provides an electronic volume for adjusting a volume when listening to a radio and a compact disc constituting a car audio, wherein the electronic of the audio can be quickly adjusted to a desired volume by controlling a variable volume during the operation of the electronic volume. When the volume of the car audio is adjusted, the volume of car audio is detected and compared with the set value by detecting the voice signal output from the microcomputer. If the voice signal applied to the speaker becomes larger than the set reference value, it is changed by the electronic volume terminal. If the volume of change is increased, and the difference between the reference value and the voice signal applied to the speaker is small, the change of the voice signal changed by the electronic volume terminal becomes small, and the user can quickly reach the desired volume, There is an effect of reaching the volume.
