The invention relates to the technical field of automobile accessories, in particular to a multifunctional automobile pedestrian warning horn and a sound production method thereof. Comprising a loudspeaker, a woofer and a heat dissipation mechanism which are installed on a loudspeaker support, the heat dissipation mechanism comprises a water tank, a first water pump, a second water pump, a first heat exchange pipeline, a first heat absorption ring, a second heat exchange pipeline, a second heat absorption ring and a semiconductor chilling plate, the water pumps are started to refrigerate water in the water tank, and the first water pump and the second water pump are started to refrigerate water in the water tank; cold water is conveyed into the first heat exchange pipeline and the second heat exchange pipeline, the first heat absorption ring is used for absorbing heat generated when a coil of the tweeter works, the first heat exchange pipeline exchanges heat with the first heat absorption ring, the second heat absorption ring is used for absorbing heat generated when a coil of the woofer works, and the second heat exchange pipeline exchanges heat with the second heat absorption ring. Therefore, damage to the loudspeaker caused by excessive accumulation of heat in the loudspeaker when the loudspeaker is used for a long time is avoided.

    本发明涉及汽车附件技术领域,具体涉及一种多功能汽车行人警示喇叭及其发声方法;包括安装与喇叭支架上的高音喇叭、低音喇叭和散热机构,散热机构包括水箱、第一水泵、第二水泵、第一换热管路、第一吸热环、第二换热管路、第二吸热环和半导体制冷片,启动水泵,对水箱内的水进行制冷,启动第一水泵和第二水泵,将冷水分别输送至第一换热管路和第二换热管路内,利用第一吸热环吸收高音喇叭的线圈工作时产生的热量,第一换热管路与第一吸热环换热,利用第二吸热环吸收低音喇叭的线圈工作时产生的热量,第二换热管路与第二吸热环换热,从而避免长时间使用喇叭时,喇叭内部的热量堆积过多,造成喇叭损坏。
