The utility model relates to the technical field of broadcasting, and discloses an automatic induction voice broadcasting device which comprises a body mechanism, a damping mechanism, a connecting mechanism and a cleaning mechanism. According to the automatic induction voice broadcasting device, the external protection shell can form a protection structure outside the broadcasting device body, thereby preventing the broadcasting device body from being directly exposed for a long time, preventing the broadcasting device body from being easily subjected to external impact, preventing the broadcasting device body from being damaged, and reducing the service life. Or external dust can be prevented from being directly and massively attached to the surface of the broadcasting device body to affect normal use of the broadcasting device body, the protection effect of the broadcasting device is improved, anti-collision mechanisms can be formed at the upper end and the lower end of the broadcasting device body through
