Description

A metal perforated sound curtain device

technical field

The invention relates to a projection screen body, in particular to a metal perforated sound-permeable screen device.

Background technique

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.

In the existing technology, for venues such as exhibition halls and exhibitions, it is necessary to provide a projection screen system. Generally, it is mainly a sound-permeable screen made of high-density weaving of fibers. If it is used as a large screen, it cannot be completely spliced, and the spliced surface is not smooth enough.

Contents of the invention

The object of the present invention is to provide a sound-transmitting curtain device that can be spliced and combined, has a smooth curved surface, can be used as a special-shaped curtain, and has metal perforations with good sound-transmitting effect in order to overcome the above-mentioned defects in the prior art.

The purpose of the present invention can be achieved through the following technical solutions:

A sound-permeable metal perforated screen device, comprising a support mechanism, a perforated screen body and a projection paint layer, the projection paint layer is attached to the face of the perforated screen body facing the audience, and the perforated screen body faces away from the audience The audience surface is fixed on the supporting mechanism.

The perforated screen body is a metal perforated screen body.

The perforated screen body is a special-shaped screen with a smooth curved surface.

The perforated screen body is an arc-shaped structure.

Compared with the prior art, the present invention has the following advantages:

1) The sound transmission effect is good, so that the sound of the whole frequency band can pass through the screen smoothly without distortion;

2) It can avoid interference with the pixels of the projector and produce "wrong mesh", so that the projector can play 100% of its performance potential;

3) It can be seamlessly spliced into a special-shaped large screen.

Description of drawings

Fig. 1 is a short structural representation of the present invention;

Fig. 2 is a schematic diagram of the arc-shaped structure of the present invention.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example

As shown in Figure 1, a metal perforated sound-permeable screen 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 perforated screen body 2 facing the audience. Above, the perforated screen body 2 is fixed on the support mechanism 1 on the side 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.

As shown in Figure 2, the perforated curtain body is set in an arc-shaped structure.
