[0002] The floor-rising screen is an advanced audio-visual device that can transform the projection area into a plane for displaying the image, bringing clear and realistic visual effects. The floor-rising screen has been widely used in home theaters, commercial presentations, conference rooms and other fields. In the actual use of the projection screen, some audio files will be watched, so a separate set of audio equipment is required during the use.

[0003] However, most of the existing ground-lifting screens need to be equipped with audio equipment separately. When the audio equipment is equipped, it is necessary to connect wires on site. However, the wiring process of the audio equipment is very cumbersome, and both the connection before use and the removal after use are very troublesome, which wastes a lot of time.
