Abstract
본 발명은 음향기기에 관한 것으로서, 특히 소스가 전환될 때, 전환된 소스의 출력 레벨을 전환 이전의 출력 레벨로 자동 보상하여 줄 수 있는 소스 전환에 따른 소스 전환에 따른 사운드 출력레벨 자동 보상 장치 및 방법에 관한 것이다. 본 발명은 주어진 소스를 디코드하여 조정된 볼륨에 따라 외부로 사운드 신호를 출력하는 사운드 출력 장치에 있어서, 세트 구동시 출력되는 소스의 외부 출력레벨을 일정 시간 동안 검출하는 출력레벨 검출부; 상기 출력레벨 검출부에서 일정 시간 검출된 아날로그 출력레벨을 디지탈 출력레벨로 변환하는 AD변환부; 및 상기 AD변환부를 통해 변환된 디지탈 출력레벨의 평균치를 기억하고, 장치가 변경되어 소스가 전환되거나 사용자가 한 장치내에서 소스를 교체하여 소스가 전환도면, 전환된 소스의 출력레벨을 검출하여 저장된 전환 이전으 출력레벨과 비교하고, 비교값이 ±α이상의 레벨이면 출력레벨이 소스 전환 이전의 출력레벨로 출력될 수 있도록 상기 볼륨조정부를 조정하는 제어신호를 출력하는 마이컴을 구비한 것을 특징으로 하여 소스 전환시 사용자가 계속하여 볼륨을 재조정 해야 하는 불편함을 덜 수 있다.The present invention relates to a sound apparatus, and in particular, when the source is switched, the sound output level automatic compensation device according to the source switching according to the source switching that can automatically compensate the output level of the switched source to the output level before the switching; It is about a method. The present invention provides a sound output apparatus for outputting a sound signal to the outside according to an adjusted volume by decoding a given source, comprising: an output level detector for detecting an external output level of a source output when driving a set for a predetermined time; An AD converter converting the analog output level detected by the output level detector for a predetermined time into a digital output level; And storing the average value of the digital output level converted by the AD converter, and detecting and storing the output level of the converted source when the device is changed and the source is switched or the user replaces the source in one device. And a microcomputer for outputting a control signal for adjusting the volume adjusting unit so that the output level is output to the output level before source switching if the comparison value is compared with the output level before the switching, and the output value is ± α or more. This saves users the trouble of having to constantly adjust volume during source switching.
