Abstract
본 발명의 카 오디오의 음량 조절방법 및 조절장치는 카 오디오의 출력 음량을 차량의 주행속도에 따라 자동으로 가변시키는 것이다.The volume control method and control device of the car audio of the present invention is to automatically change the output volume of the car audio according to the running speed of the vehicle.
본 발명은 차량의 주행속도에 따라 카 오디오의 출력음량을 자동으로 조절하여 차량의 주행속도에 관계없이 카 오디오의 출력신호를 항상 적정한 크기로 청취할 수 있도록 하는 것으로서 운전자가 차량을 운전하면서 미리 설정한 출력음량의 크기를 신호대 잡음비로 설정하여 두고, 차량의 주행시 현재 출력하는 카 오디오의 출력음량과 차량의 주행속도에 따른 S/N비를 검출하며, 검출한 S/N비와 미리 설정한 S/N비를 비교하여 비교결과에 따라 카 오디오의 출력음량을 자동으로 조절한다.The present invention automatically adjusts the output volume of the car audio according to the driving speed of the vehicle so that the output signal of the car audio can always be heard at an appropriate size regardless of the driving speed of the vehicle. Set the output volume level as the signal-to-noise ratio, detect the car audio output volume and the S / N ratio according to the vehicle's driving speed when the vehicle is running, and detect the detected S / N ratio and the preset S. Compare the / N ratio and automatically adjust the car audio output volume according to the comparison result.
그러므로 본 발명에 의하면, 차량의 주행속도에 따라 운전자가 일일이 카 오디오의 출력음량을 조절할 필요없이 항상 적정한 크기로 카 오디오의 출력신호를 청취할 수 있고, 운전자가 차량의 안전운전에 보다 많은 신경을 쓸 수 있어 안전사고의 발생을 방지할 수 있다.Therefore, according to the present invention, the driver can always listen to the output signal of the car audio at an appropriate size without having to adjust the output volume of the car audio according to the driving speed of the vehicle, and the driver pays more attention to the safe driving of the vehicle. It can be used to prevent the occurrence of safety accidents.
