The invention discloses a large-stroke ceiling microphone lifter which comprises a lifting hook piece, a shell, a baffle structure and a limiting structure. The upper end of the shell and a top plateare assembled through screws; the lower end of the shell and a bottom plate are assembled through screws; meanwhile, a fixing plate is fixedly installed on the bottom plate; a professional socket is installed on the fixing plate; a control mainboard is arranged on the upper side of the professional socket, and is installed on the fixing plate through screws; the bottom of the bottom plate is connected with a microphone device through a microphone wire; a control box body is installed on the outer side wall of the shell; a synchronous motor and a limiting motor are installed in the control boxbody; meanwhile, a reel disc is movably connected to the interior of the shell; and a bull gear is fixedly connected to the reel disc. According to the large-stroke ceiling microphone lifter, the synchronous motor drives the bull gear through a transmission gear, so that rotation of the reel disc is achieved; and the reel disc realizes the lifting of the microphone device by winding and unwindingthe microphone wire.
