description The present invention relates to a dust cover with a structure for preventing sound pressure from decreasing while preventing foreign substances from being introduced into a horn. According to one embodiment of the present invention, the dust cover with the structure for preventing the sound pressure from decreasing, in a dust cover which radiates the sound pressure generated in a horn to the outside of the horn, comprises: an upper surface unit which comes in contact with the inside of the horn; a bottom surface unit which comes in contact with the outside of the horn; a first side surface unit and a second side surface unit connected to the upper surface unit and the bottom surface unit; and a blocking unit which blocks foreign substances from being introduced into the horn from outside. The blocking unit includes at least one blocking wall, and has at least one hole through which the sound pressure generated inside the horn is radiated. 본 발명은 경음기의 내부로 이물질이 유입되는 것을 방지하면서 음압이 저하되는 것을 방지하는 구조를 갖춘 음압 저하 방지 구조의 더스트 커버에 관한 것이다. 본 발명의 실시 예에 따른 음압 저하 방지 구조의 더스트 커버는 경음기의 내부에서 발생되는 음압을 상기 경음기의 외부로 방사시키는 더스트 커버에 있어서, 상기 경음기의 내부와 접하는 상면부와, 상기 경음기의 외부와 접하는 저면부와, 상기 상면부 및 상기 저면부와 연결되는 제1 측면부 및 제2 측면부와, 상기 외부로부터 이물질의 내부 유입을 차단하는 차단부를 포함하고, 상기 차단부는 적어도 하나 이상의 차단벽을 포함하고, 상기 차단부에는 상기 내부에서 발생되는 음압이 방사되는 적어도 하나 이상의 홀이 생성된다.
