Abstract

The present invention provides a self-sound projection display device, wherein the display device includes a frame, a screen and a plurality of transducers, the screen includes a sound-emitting substrate and a side surface covering the sound-emitting substrate for receiving and displaying The optical film of the image; the sound-emitting substrate comprises a honeycomb core board and a skin, the honeycomb core board comprises a plurality of honeycomb cells staggered along a first direction and a second direction; the skin covers the honeycomb The openings at both ends of the grid; a plurality of the transducers are arranged on the other side surface of the sound-emitting substrate, and the frame is used to carry the screen and the plurality of the transducers. The present invention can clearly distinguish the left and right channels of audio, so as to improve the user's audio-visual experience.

Description

technical field [0001] The present invention relates to the technical field of projection screens, in particular to a self-sound projection display device. Background technique [0002] With the development of projection technology, the multimedia audio-visual system displayed by projection is more and more accepted by people. like figure 1 As shown, most of the multimedia audio-visual systems displayed by projection are composed of a projector E1, a projection screen E2, a loudspeaker E3 and a control system E4. However, due to the different positions of the projection screen E2 and the loudspeaker E3, during projection and playback, the audio-visual experience of asynchrony of sound and image will inevitably occur, so that people cannot obtain a good audio-visual playback experience. [0003] Therefore, in order to prevent the sound and image from being out of synchronization, it has become the mainstream development direction to use the projection screen itself to vibra...
