Embodiment
[0018] like figure 1 As shown, a sound-permeable metal perforated curtain device includes a support mechanism 1, a perforated screen body 2 and a projection paint layer 3, and the projection paint layer 3 is attached to the face of the perforated screen body 2 facing the audience, so The perforated screen body 2 described above is fixed on the support mechanism 1 facing away from the audience. The perforated screen body 2 is a metal perforated screen body. First, install the support mechanism 1 at the relevant position; then put the metal perforated screen body 2 under force on the support mechanism 1; finally, select different projection paints to attach to the metal perforated screen body 2 according to different projection methods.
[0019] like figure 2 As shown, the perforated curtain body is set as an arc-shaped structure.

The invention relates to a metal punching acoustic transmission curtain device which comprises a supporting mechanism, a punching curtain body and a projection paint layer, wherein the projection paint layer is adhered to the surface, facing to the audience, of the punching curtain body; and the surface, back on to the audience, of the punching curtain body is fixed on the supporting mechanism. Compared with the prior art, the metal punching acoustic transmission curtain device has the advantages of splicing combination, smooth curved surface, feasibility of a special-shaped curtain, good acoustic transmission effect and the like.
Description
technical field [0001] The invention relates to a projection screen body, in particular to a metal perforated sound-permeable screen device. Background technique [0002] The projection screen is one of the most commonly used products in the peripheral equipment of the projector, and the projection screen is the abbreviation of the projection screen. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. With the continuous improvement of people's living standards, domestic home theaters have developed by leaps and bounds, and have gone from simple projection effects to the pursuit of acoustics and optics. A new type of projection screen-sound-transmitting screen has attracted widespread attention. , It changes the current layout of theaters in one fell swoop, and audio equipment can be installed behind the screen or embedded in the wall without affecting the sound quality and projection effect. [0003] In the exi...
