Abstract
본 발명은 카오디오용 자동볼륨레벨조절장치에 관한 것으로, 차량실내의 일정한 곳에 설치되어 차내의 소음 상태를 전기적인 신호로 검출하는 마이크로 폰과, 이 마이크로폰에 의해 검출된 소음신호를 비교판단하고 그 판단결과에 따라 카오디오 볼륨레벨 제어신호를 발생시켜 카오디오부의 오디오프로세서를 조절하는 마이컴으로 이루어져, 차량실내에 설치된 마이크로 폰으로부터 검출된 소음레벨을 비교판단하고 그 판단된 결과에 따라 카오디오의 음량을 자동조절하도록 하므로써, 차량실내의 소음상태에 관계없이 항상 최적의 오디오음량을 유지할 수 있어 시스템의 최적성을 향상시킬 수 있음은 물론 소음상태에 따라 탑승자가 별도의 볼륨레벨동작을 수행하지 않아도 되므로 이에 따라 사용의 편리성도 향상되도록 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic volume level adjusting device for car audio, comprising: a microphone which is installed at a certain place in a vehicle room and detects a noise state in a vehicle as an electrical signal, and compares the noise signal detected by the microphone with the It consists of a microcomputer that generates a car audio volume level control signal according to the determination result and controls the audio processor of the car audio unit. The noise level detected by the microphone installed in the vehicle is compared and judged, and the volume of the car audio is determined according to the determined result. By automatically adjusting the system, the optimum audio volume can be maintained at all times regardless of the noise condition in the vehicle, thereby improving the system's optimality and the passengers do not have to perform separate volume level operation according to the noise condition. Accordingly, the convenience of use is also improved.
