Abstract

음향재생장치는 사용자의 위치에 따라 최적의 음향이 재생될 수 있도록 자동제어하는 것이다. 이를 위하여 최적의 음향을 재생하고 싶은 위치를 설정하기 위한 위치설정수단과, 위치설정수단의 설정 결과에 따라 디지탈신호 처리된 음향신호의 출력시간과 볼륨레벨을 제어하기 위한 제어부를 포함하도록 구성된다. 따라서 사용자의 위치에 따라 스피커에서 출력되는 재생신호의 재생시간과 재생레벨을 자동조절하여 청취도를 높일 수 있다.The sound reproducing apparatus automatically controls the optimum sound to be reproduced according to the position of the user. To this end, it is configured to include a positioning means for setting a position where the optimum sound is to be reproduced, and a controller for controlling the output time and volume level of the digital signal processed sound signal according to the setting result of the positioning means. Therefore, the listening level can be improved by automatically adjusting the playing time and the playing level of the playing signal output from the speaker according to the position of the user.
