Description
Technical field
The utility model relates to a kind of curtain, relate in particular to the harmless entrant sound curtain of a kind of high definition, product is the necessary component of the supporting screen of the projection equipments such as projector, film projection machine, slide projector for the manufacture of home theater, commercialization, culture and education and professional theater screen.
Background technology
There are on the market at present various projections to use the curtain product.Different with principle according to occupation mode, can be divided into very eurypalynous projection screen: back-projection screen, just throw the holographic curtain of curtain, entrant sound curtain, 3D etc.The curtain that this utility model relates to is the entrant sound curtain, namely allows stereo set to be placed on curtain behind, and in the time of projection, sound can see through curtain and be communicated to spectators, realizes sound bearing and picture orientation uniformity.The entrant sound curtain is different with processing mode according to material, mainly is divided into punching class entrant sound curtain, braiding entrant sound curtain.
1. punching class entrant sound curtain is take soft PVC curtain or glass curtain as the basis, with punching or laser form, gets Φ=0.2-1.5mm in the same size aperture arranged in a uniform on curtain, the purpose of propagating by aperture to reach sound wave.The entrant sound curtain of processing by this way, percent opening is the 5%-10% of curtain surface area, exists perforate excessive, in the time of the projection picture, outside certain distance, can clearly see affecting image quality by the curtain aperture.On the entrant sound effect, this curtain can make sound frequency serious unbalanced propagation phenomenon occur.According to the sound wave characteristics, through measuring, curtain can produce 5DB one 10D13 decay to the sound frequency more than the 10K HZ, and it is stuffy to show as sound on the sense of hearing, thereby needs to use balanced device that high-frequency signal is compensated.
2. common common braiding entrant sound curtain adopts polyester fiber silk parcel PVC, and carry out the cross weaving manner and make, percent opening 8%, the material wire diameter is 0.32-0.42mm, per inch graticule density is the 48X48 line.This type of entrant sound curtain, because wire diameter is thick, percent opening is high, in the time of projected picture, main manifestations is that picture is fuzzyyer; More seriously owing to be the common braiding of longitude and latitude, cause causing easily interference between the pixel of display chip of projection screen braiding lines and projector, make to occur interference fringe on the picture.Namely the spatial frequency of the frequency of occurrences of projection screen litzendraht wire and projection chip pixel approaches, so " the moire fringes Moir é effects " of similar wave occur.This is the factor that has a strong impact on image quality.
Common braiding class entrant sound curtain because percent opening is high, causes a large amount of light to see through aperture, has lost picture brightness.And the light of transmission loss can carry out secondary reflection at curtain wall behind again, affects again curtain, and picture contrast is descended.
The utility model content
For various common entrant sound curtains drawback in use, the purpose of this utility model provides and a kind ofly can obtain excellent sound and penetrate effect and high-quality clear picture, satisfies the harmless entrant sound curtain of high definition that high-end movie theatre and fan use.
In order to address the above problem, the utility model is achieved through the following technical solutions:
High definition of the present utility model can't harm the entrant sound curtain, and it comprises that high definition can't harm entrant sound curtain face, and this act face is graticule twill double braid layer, and described graticule twill double braid layer is for to upper left or 25 ° ± 5 ° the twill weave of tilting to the right.
Further, this act face adopts glass fiber as the line base, the surface of line base parcel PVC material.
Further, the diameter of described line base is 0.3mm ± 8%.
Further, the behind of the harmless entrant sound curtain face of described high definition is provided with black entrant sound shading screen cloth extra play.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model can place loudspeaker, sound equipment curtain behind, and the impact of sound is only had-2.5db, provide best picture and and sound effect, it is consistent that sound origination point and projection picture are located, and obtains good viewing effect.Can be applicable to the fields such as private movie theatre, commercial cinema, hotel club business presentations, culture and education.
2. curtain adopts glass fiber as the line base, and parcel PVC material is adopted on the surface, adopts 0.3mm ± 8% wire diameter.Effect: glass fibre has the high-strength and ageing resistance performance, makes curtain smooth durable in use.The use of glass fibre can reflect certain light, and the projected picture color is saturated bright-coloured, has optimized result of use.The PVC of surface parcel is the picture presentation layer.The utility model, having can be clear, and environmental protection meets the fire protection flame retarding requirement.
3. curtain adopts graticule twill double braid, and to upper left or tilt 25 ° ± 5 ° to the right, its notable feature is the meander line that warp presents certain rule.Effect one: the pixel of projector's display chip is that small square is according to the compact arranged grid of Longitude-latitude ten font, its diagonal is 45 degree, the utility model improves from knitting skill, braiding is presented to upper left or tilt 25 ° ± 5 ° to the right, misplace thereby reach with the display chip pixel, and avoid 45 degree diagonal of pixel, fundamentally reach the purpose of eliminating moire fringes; Effect two: utilize weaving manner to make warp present tortuous the variation, the direction of parallel can't be overlapped with the warp direction of pixel, thereby play the dislocation effect, further avoid occurring moire fringes.Effect three: adopt the entrant sound curtain of this fabrication techniques, present litzendraht wire levels structure, be full of aperture between tissue, few light can directly pass curtain, and sound then can be walked around interfibrous space in few loss situation, penetrate.Effect four: compare with common braiding entrant sound curtain, this uses in the novel practical application, can obviously improve the picture acutance.
4. the utility model adds a black entrant sound shading screen cloth behind at curtain.Adopt the knitting skill of front, in projection is used, still have a small amount of light penetration curtain, implement this technology, additional black entrant sound screen cloth can prevent that a small amount of light that penetrates from shining the curtain objects such as wall behind, and again reflex to curtain behind, and picture contrast is descended, so that affect picture.This technology mainly is on the basis that keeps entrant sound, and isolated light penetration and back light disturb the curtain picture.
