When the projection screen curtain needs to be used, a curtain is pulled up to shield light, in this way, the position of the curtain is used, by means of control over the size and distance of holes formed in the projection screen, sounds can penetrate through the screen without being blocked, and the projection screen curtain is good in sound transmitting effect and capable of perfectly integrating images and the sounds, and an excellent audio video environment can be created.

Description

Technical field [0001] The invention relates to a projection screen, in particular to a curtain type projection screen, belonging to the technical field of projection instruments. Background technique [0002] The projection screen is a tool used to image the image beam projected by the projector on a flat surface.

Problems solved by technology

[0002] A projection screen is a tool used to image the image beam projected by the projector on a flat surface. Common projection screens include wall-mounted projection screens and floor-drawn projection screens. The former is usually installed in places with ceilings or walls. The latter can be moved anywhere. In view of the special shape of the projection screen, the structure of the existing projection screen on the market is relatively complicated, and the structure design is not reasonable, resulting in low space utilization and high cost.

[0003] Many families have beautiful curtains installed, but when the curtains are pulled up, they are useless except for viewing. The larger the window area in the home, the larger the area of ​​the curtains. It is wrong to not use such a large area. It's a pity

[0004] At present, there is very little research on sound-transmitting screens in China, and some products that claim to be sound-transmitting screens simply punch holes without considering the size of the holes and the spacing of the holes, and the performance of the screen itself has not been well guaranteed.
