Abstract
The utility model relates to an acoustical transmission projection curtain. Through holes are uniformly arranged on the projection curtain, the diameter phi of the through hole is ranged from 0.2 mm to 1.5 mm, and the percentage PC of a hole area is 5 to 7 percent. By controlling the size of the holes and the space between the holes on the projection curtain, the sound can pass through the curtain without being blocked, so an acoustical transmission projection curtain with good acoustical transmission effect and perfect combination of image and sound is provided, and an excellent audio-visual environment can be created. In addition, the product also has the properties such as excellent elasticity, convenience in carry, extendability, bending resistance, washability, difficulty in infection of dust, durability and the like, and can be widely used in the fields emphasizing the environmental effect of the cinema such as public cinema, household theater, business club, five-star hotels and the like.
Description
Technical field
The utility model relates to a kind of entrant sound projection screen.
Background technology
Projection screen is one of product of the most normal use in projector's peripheral equipment, and projection screen is the abbreviation of projection screen.If the collocation of projection screen and projector is proper, can obtain the drop shadow effect of high-quality.
Along with improving constantly of people's living standard, the domestic households movie theatre has obtained great-leap-forward development, and from simple drop shadow effect to acoustics, the many-sided pursuit of optics, a kind of novel projection screen---entrant sound screen has caused widely to be paid close attention to, it changes the present placement general layout of movie theatre at one stroke, stereo set can be installed in the rear of screen or be bumped in the wall to install and do not influence tonequality and drop shadow effect.But present domestic entrant sound screen research is considerably less, and some to be known as be the just simple punching of product of entrant sound screen, do not consider the size in hole and the spacing control in hole, and the performance of screen own also fails to obtain good assurance.
In addition, existing up-to-date projection screen is to be base material with the woven cloth of terylene, and part only is compounded with the PVC reflectance coating, and its product has been difficult to guarantee good reflection and projection performance.
The utility model content
Technical problem to be solved in the utility model provides a kind of entrant sound projection screen with good projection effect.
The technical solution of the utility model is: a kind of entrant sound projection screen, evenly have through hole on the described projection screen, and described through-hole diameter φ is at 0.2mm～1.5mm, and hole area number percent PC is 5%～7%.
The computing formula of hole area number percent PC is:
, wherein h represents same row hole longitudinal pitch, l represents same round horizontal spacing, φ indication window diameter.
Preferably, described projection screen is composited by reflectance coating and photomask, and this kind composite structure is given the projection screen excellent elasticity.It is colourless or white that reflectance coating of the present utility model is generally, and material can be selected the PVC film for use, mainly plays reflex; Photomask then is generally secretly/black, and material also can be selected the PVC film for use, mainly has been interception, and its light that can block projection is not penetrated.
The utility model is by size and pitch of holes control for perforate on the projection screen, make sound pass screen and can not be intercepted, and then provide a kind of entrant sound effect good, the perfect entrant sound projection screen that merges of image and sound can be able to be built outstanding audio-visual environment.This product has excellent elasticity, portability, extensibility, folding resistance, clanability concurrently, is difficult for being stained with ash and performance such as durable in use in addition, can be widely used in public and home theater, the commercial affairs of paying attention to the movie theatre environmental effect and understand in one's power places such as five-star hotel.

Fig. 1 is the plane structure chart of the utility model entrant sound projection screen.
Fig. 2 is the sectional structure chart of the utility model entrant sound projection screen.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of entrant sound projection screen evenly has through hole 2 on the described projection screen 1, and described through hole 2 diameter phi are at 0.2mm～1.5mm, and hole area number percent PC is 5%～7%.
The computing formula of hole area number percent PC is:
, wherein h represents same row hole longitudinal pitch, l represents same round horizontal spacing, φ indication window diameter.
In the utility model restricted portion, desirable than the macropore area percentage when hole diameter is big, when hole diameter hour desirable less hole area number percent.
With reference to Fig. 2, described projection screen is composited by reflectance coating 3 and photomask 4.
Claims (2)
1. entrant sound projection screen, it is characterized in that: evenly have through hole on the described projection screen, described through-hole diameter φ is at 0.2mm～1.5mm, and hole area number percent PC is 5%～7%.
