The invention relates to a movable audio-video showing device. The movable audio-video showing device comprises a bracket, a main screen, an auxiliary screen, a transmission mechanism and a master controller, wherein the transmission mechanism is mounted on the bracket and comprises a transmission piece, the transmission piece is connected with the auxiliary screen, the auxiliary screen is driven by the transmission piece of the transmission mechanism, and the main screen and the auxiliary screen are respectively in communication connection with corresponding connection ends of the master controller. Or, the auxiliary screen also can be a demonstration panel. By utilizing a high-precision automatic control technology, the movable audio-video showing device ensures that the audio-video content shown by multiple communication media or the content of a fixed layout is coordinated and matched with the motion state of the auxiliary screen or an auxiliary demonstration panel, so that a virtual-real interactive transmission effect is formed.
