Abstract

본 발명은 볼륨 자동 조절장치에 관한 것으로, 종래의 볼륨제어장치는 오디오 청취시, 주위의 소음에 의해 청취가 불가능해지며 항상, 일일이 볼륨의 크기를 조정해 주어야만 하는 불편함이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 주위소음을 측정하여 이를 현재 볼륨레벨값과 감산하여 실제소음값을 계산하고, 그 계산한 값과 이전 실제소음값을 감산하여 그 결과를 볼륨제어값으로 출력하도록 함으로써, 다시 말해, 주위소음중에서 기기 자체에서 나는 소리 즉, 스피커음향에 의한 소음과 실제소음을 측정하여 그 실제소음정도를 볼륨제어에 이용함으로써 오디오 볼륨을 자동으로 조절할 수 있는 효과가 있다.The present invention relates to an automatic volume control device, the conventional volume control device, when listening to audio, it is impossible to hear by the ambient noise, there was always the inconvenience that must adjust the size of the volume one by one. The present invention is to solve the conventional problems by measuring the ambient noise and subtract it from the current volume level value to calculate the actual noise value, the calculated value and the previous actual noise value by subtracting the result to the volume control value In other words, it is possible to automatically adjust the audio volume by measuring the sound produced by the device itself, that is, the sound generated by the speaker sound, and using the actual noise level in the volume control.
