Abstract

일반적인 전자기기의 음량조절장치는 주변소음이 큰 경우에는 출력되는 음량을 크게해야 하고 또 주변소음이 작은 경우에는 음량을 줄여 주어야 하는 번거로움이 있었다.In general, the volume control device of an electronic device has a problem in that the volume of the output is increased when the ambient noise is high and the volume is reduced when the ambient noise is low.

그리하여 전자기기의 음량조절 볼륨을 수시로 조정해야 하는 번거로움이 있으며 일시적으로 증가된 주변소음에 의해 스피커의 출력음을 듣지 못하거나, 일시적으로 감소된 주변소음에 의해 매우 큰 음으로 스피커 출력음을 듣게 되어 누구나 불쾌감을 느끼게 되는 경우가 종종 있었다.Therefore, it is cumbersome to adjust the volume control volume of the electronic device from time to time, and you may not hear the speaker's output sound due to the temporarily increased ambient noise, or you may hear the speaker's output sound very loudly due to the temporarily reduced ambient noise. At times, everyone was often offended.

이와 같은 문제점을 감안하여 본 발명은 주변소음의 변동을 감지하여 사용자가 원하는 출력레벨을 낼 수 있도록 증감된 음량을 발생시킬 수 있게 한 것이며 그럼으로써 사용자는 주변 소음의 변동에도 불구하고 항시 자신이 설정한 음의 세기로 음을 듣게 되는 것이다.In view of such a problem, the present invention enables the user to generate a volume that is increased or decreased so that the user can achieve a desired output level by detecting a change in ambient noise. You will hear the notes at one tone strength.

즉 본 발명은 오디오세트나 TV 라디오등 각종 전자기기에서 스피커로 출력되는 음량을 주변의 음량에 맞추어 사용자가 원하는 출력레벨로 적절히 자동조절되게 하는 전자기기의 자동음량 조절장치에 관한 기술이다.That is, the present invention relates to an automatic volume control device for an electronic device that automatically adjusts the volume output from a speaker from various electronic devices such as an audio set or a TV radio to a desired output level according to the surrounding volume.
