According to the present invention, disclosed is a vehicular horn. A prevention structure capable of blocking the inflow of foreign substances containing moisture is applied to a horn case, and thus laws related to a sound pressure can be complied with and stable performance maintenance can be realized. The vehicular horn includes a case (20) accommodating a sound source generating unit (10) and a sound pressure releasing unit (30) releasing the sound pressure generated from the sound source generating unit (10) to the outside. The sound pressure releasing unit (30) is positioned in the lower portion of the case (20) and provided with a shielding structure unit blocking a foreign substance from flowing in from the outside and an opening portion capable of communicating with the outside. The shielding structure unit is formed in each of a front surface portion (31) and a bottom surface portion (32) of the sound pressure releasing unit (30). The opening portion is formed in each of a side surface portion (33) and a rear surface portion (34) of the sound pressure releasing unit (30).

    본 발명은 경음기의 케이스에 대해 수분을 포함한 각종 이물질의 유입을 차단할 수 있는 방지 구조를 적용함으로써 음압과 관련된 법규의 만족과 성능의 안정적인 유지를 구현할 수 있는 차량용 경음기를 개시한다. 전술한 차량용 경음기는 내부에 음원 발생부(10)를 수용하는 케이스(20), 및 상기 음원 발생부(10)로부터 생성된 음압을 외부로 방사하는 음압 발산부(30)를 포함하고, 상기 음압 발산부(30)는 상기 케이스(20)의 하부에 위치하며, 외부로부터 이물질의 내부 유입을 차단하는 차폐 구조부, 및 외부와 교통 가능한 개구부를 구비하고, 상기 차폐 구조부는 상기 음압 발산부(30)의 전면부(31)와 저면부(32)에 각각 형성되고, 상기 개구부는 상기 음압 발산부(30)의 측면부(33)와 배면부(34)에 각각 형성된다.
