Abstract

본 발명은 자동차 또는 기차 주행시 발생되는 소음을 상쇄시키는 전자 방음벽 장치에 관한 것으로 기존 방음벽이 효과적으로 소음을 차단시키지 못하고 조광권 및 조망권을 상실시키는 한편 통풍도 되지 않는 문제점을 해결하기 위한 것이다.The present invention relates to an electronic soundproof wall device that cancels the noise generated when driving a car or train to solve the problem that the existing soundproof wall does not effectively block the noise and loses the right to light and view while not being ventilated.

본 발명은 동일한 소리 주파수 신호를 두 개의 대향되게 설치된 스피커에서 동일하게 출력시키면 양스피커에서 출력된 소리가 서로 상쇄되어 버리는 원리를 이용한 것으로 본 발명은 소음원으로부터 발생된 소리를 집음하여 전기적 신호로 변환시키는 소리 집음수단에서 변환된 전기적 신호를 증폭시키는 신호 증폭수단과, 신호 증폭수단에서 증폭된 전기적 신호를 소리신호로 변환시켜 출력시키는 소리 출력수단을 구비하므로써 이루어진다.The present invention utilizes the principle that the sound output from both speakers cancels each other when the same sound frequency signal is output identically from two oppositely installed speakers, and the present invention collects sound generated from a noise source and converts the sound into an electrical signal. And a sound output means for amplifying the electric signal converted by the sound collecting means, and a sound output means for converting the electric signal amplified by the signal amplifying means into a sound signal and outputting the sound signal.
