Abstract

The invention discloses a projection screen and a laser projection system, and belongs to the field of laser projection. The projection screen comprises a sound production screen, a frame body, an elastic supporting part, a first damping layer, a second damping layer and an exciter. The frame body is clamped at the edge of the sound production screen, the elastic supporting part is located betweenthe side wall of the sound production screen and the frame body, the first damping layer is located between the projection surface of the sound production screen and the frame body, and the second damping layer is located between the surface away from the projection surface of the sound production screen and the frame body. The elastic supporting part is separated from the first damping layer anfthe second damping layer. Thus, when the projection screen is hung, the glass fiber skin in the sound production plate can be prevented from being embedded into the elastic supporting part, when thesound production plate is driven by the exciter to vibrate, the vibration amplitude of the sound production plate at the edge cannot be limited, and the sound production effect of the projection screen is further improved.

Description

technical field [0001] The present application relates to the technical field of laser projection, in particular to a projection screen and a laser projection system. Background technique [0002] The laser projection system includes a projection screen and laser projection equipment. The laser projection equipment can project pictures on the projection screen to realize functions such as video playback. [0003] Currently, it is possible to integrate the sound-generating components of a laser projection system into the projection screen. For example, please refer to figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a projection screen provided by related technologies, figure 2 yes figure 1 An exploded view of the projection screen shown. The projection screen may include: a sounding screen 01 , a frame body 02 , a cover plate 03 and an exciter 04 . The sounding screen 01 may include: an optical screen 011 and a sounding board 012 , and a scre...
