Wireless voice receiving device

A wireless voice receiving device comprises a shell and a control panel located inside the shell, and the control panel is connected with buttons, a display screen, a wireless module and at least one external interface, wherein the buttons and the display screen are located on the surface of the shell, and the external interfaces are located on the upper and lower end faces of the shell. According to the utility model employing the above technical scheme, and in order to guarantee the safe transmission of railway, the SWX-D type wireless voice receiving device is researched and developed especially for the recording problem of a flat shunting controller. The wireless voice receiving device receives an audio signal of the flat shunting controller wirelessly, processes the audio signal and then sends the audio signal to a TAX box recording unit, thereby solving the recording problem of the flat shunting controller, and providing forceful scientific evidences for the supervision, management and postmortem analys
