Abstract

본 발명은 소음측정기를 이용한 카오디오의 자동 볼륨조절장치에 관한 것으로, 카오디오의 마이크로 프로세서에 차량의 내부에서 발생되는 소음의 크기를 측정하여 전하는 소음 센서와, 운전자가 조절한 카오디오의 볼륨의 크기에 따른 신호를 전하는 볼륨 센서와, 상기의 소음 센서와 카오디오의 볼륨 센서로부터 크기에 해당하는 신호를 입력받으면서 두 신호의 크기를 조절하여 소음의 볼륨이 더 클 경우 카오디오의 볼륨도 자동으로 조절하기 위한 볼륨 콘트롤 신호를 출력하는 마이크로 프로세서들로 구성하되, 운전자가 최적의 카오디오 볼륨을 조절하도록하는 단계와, 자동차의 내부에서 발생되는 소음을 소음 센서를 통해 측정하는 단계와, 소음 센서에 의한 소음이 카오디오의 볼륨보다 큰가를 비교하는 단계와, 소음이 크면 볼륨을 1스텝 증가하고 다시 소음과 볼륨의 크기를 비교하는 단계와, 소음이 크지 않으면 현재의 소음이 최적인 가를 확인하는 단계와, 최적의 볼륨값보다 작지않은 가를 비교하여 큰 경우에는 볼륨을 1스텝 감소시킨 후 소음과 볼륨을 비교하도록함으로써 카오디오의 볼륨을 소음에 따라서 증감시키면서 항상 최적의 사운드를 들을 수 있도록 한 것이다.The present invention relates to an automatic volume control device for a car audio using a noise measuring device. The noise sensor and the volume of the car audio adjusted by the driver are measured and transmitted to the micro processor of the car audio by measuring the amount of noise generated inside the vehicle. The volume sensor delivers the signal according to the size, and the volume of the car audio is automatically adjusted when the volume of the noise is higher by receiving the signal corresponding to the size from the noise sensor and the volume sensor of the car audio. Microprocessors that output a volume control signal to adjust, allowing the driver to adjust the optimal car audio volume, measuring the noise generated inside the car through a noise sensor, Comparing the noise caused by the car audio with the volume more than the volume of the car audio. Compare the volume of the noise with the volume again, check if the current noise is optimal if the noise is not loud, and reduce the volume by one step if it is not less than the optimal volume. By comparing the volume with the volume, the volume of the car audio is increased or decreased according to the noise so that the optimum sound can always be heard.
