Abstract

The invention provides a self-sound-production projection display device. The display device comprises a frame, a screen and a plurality of transducers. The screen comprises a sound production substrate and an optical film which covers the surface of one side of the sound production substrate and is used for receiving and displaying an image. The sound production substrate comprises a honeycomb core plate and a skin, and the honeycomb core plate comprises a plurality of honeycomb grids which are arranged in a staggered manner along a first direction and a second direction; the skin covers openings in the two ends of the honeycomb grids; and the plurality of transducers are arranged on the surface of the other side of the sound production substrate, and the frame is used for bearing the screen and the plurality of transducers. According to the invention, a left sound channel and a right sound channel of an audio can be obviously distinguished to improve an audio-visual feeling of a user.

Description

Technical field[0001]The invention relates to the technical field of projection screens, in particular to a self-sounding projection display device.Background technique[0002]With the development of projection technology, multimedia audio-visual systems that display through projection are more and more accepted by people. Such asfigure 1 As shown, most of the multimedia audio-visual systems that display by projection are composed of a projector E1, a projection screen E2, a sound reinforcement box E3, and a control system E4. However, due to the different positions of the projection screen E2 and the sound reinforcement box E3, when performing projection playback, the audiovisual experience of unsynchronized sound and image will inevitably occur, making people unable to obtain a good audiovisual playback experience.[0003]Therefore, in order to avoid the unsynchronized sound and image, the use of the projection screen itself to vibrate to replace the traditional sound reinforcement sp...
