Abstract
The invention provides a curtain type projection screen. The curtain type projection screen comprises a roller and a screen curtain, the screen curtain is installed on the roller, through holes are formed in the screen curtain, loudspeakers are installed on the two sides of the screen curtain, a hanging ring is arranged a the bottom of the screen curtain, the roller is fixed to a window through fixing frames, a shaft is installed in the roller and connected with a limiting stopper, the limiting stopper is connected with a bearing, the bearing is connected with a motor, the motor is connected with a wire, the wire is connected with a control box, a plug is installed at the tail end of the wire, and hanging pieces are arranged on the roller. 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
The present invention relates to a kind of projection screen, be specially a kind of window curtain type projection screen, belong to projection device equipment technical field.
Background technology
Projection screen is a kind of image strip imaging apparatus being in the plane used for projector being projected, common projection screen has wall-hanging projection screen and ground-pulling type projection screen, the former is arranged at the place of ceiling or wall usually, the latter then can move everywhere, in view of the shape that projection screen is special, and the projection screen on existing market, its structure is comparatively complicated, structural design is also unreasonable, cause space availability ratio low thus, and cost is also high.
A lot of family is all provided with very beautiful curtain, but curtain when pulling up except viewing and admiring just without any use, the window areas of family is larger, and the area of curtain is also larger, and it is very unfortunate for not being used to so large area.
Current domestic entrant sound screen research is considerably less, and some to be known as be the product just simple punching of entrant sound screen, do not consider that the size in hole and the spacing in hole control, and the performance of screen own also could not obtain good guarantee.
Summary of the invention
Overcome existing defect during the technical problem to be solved in the present invention, a kind of window curtain type projection screen is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of window curtain type projection screen of the present invention, this projection screen comprises cylinder and curtain, described curtain is loaded on cylinder, described curtain is provided with through hole, loudspeaker is equipped with in described curtain both sides, link is provided with bottom described curtain, described cylinder is fixed on window by fixed mount, and described cylinder is built with axle, and described axle is connected with stop, described stop is connected with bearing, described bearing is connected with motor, and described motor is connected with wire, and described wire is connected with control enclosure, described wire end is equipped with plug, and described cylinder is also provided with lacing film.
Further, described curtain is composited by reflectance coating and photomask.
Further, described curtain evenly has through hole, described through-hole diameter φ is at 0.2mm ~ 1.5mm, and via area number percent PC is 5% ~ 7%.
Further, motor switch is provided with in described control enclosure.
The beneficial effect that the present invention reaches is:
1, pass through the size for perforate on projection screen and pitch of holes control, sound can not be able to be blocked through screen, and then provide the acoustical transmission projection curtain that a kind of entrant sound effect is good, image and sound perfection can be merged, outstanding audio-visual environment can be built.
2, can being packed up when not using projection screen, not affected the normal use of curtain, curtain then must be needed to pull up shield lights when needing to use projection screen, so just utilize and gone up the position of curtain.
3, compact to design, space occupancy rate is low, and easy to assembly, with low cost.
