Abstract

음을 발생시키는 혼 보디와 상기 보디에서 발생된 음을 확산시켜주는 확산구로 구성되는 경음기에 있어서, 상기 확산구의 중간부 전측부에 상하길이방향으로 입설되는 힌지축과 일체로 형성되어 확산구를 개폐하는 개폐판을 형성하고, 상기 힌지축의 상단은 크랭크 기구를 통하여 엔진의 부압에 의하여 진퇴 동작되는 액튜에이터의 피스톤과 연결하여서 된 엔진 부압을 이용한 음압 가변 경음기를 제공함으로써, 자동차가 일정속도 이상으로 주행하는 경우에는 음압이 크게 발생되고, 정지 또는 서행시에는 음압이 작게 발생되도록 하여 불필요한 소음 공해 발생을 방지할 수 있게 한 것이다.In a horn composed of a horn body for generating sound and a diffuser for diffusing the sound generated by the body, the horn body is formed integrally with the hinge shaft which is vertically extended in the front side of the middle portion of the diffuser to open and close the diffuser And a negative pressure variable horn using the engine negative pressure connected to the piston of the actuator which is operated by the negative pressure of the engine through the crank mechanism. In this case, a large sound pressure is generated, and when a stop or slow motion, a low sound pressure is generated to prevent unnecessary noise pollution.
