And the screen that only has light shield layer S1 and reflection layer S2 in the side of fiber construct S0 is, polyurethane by for example will containing carbon black and the two-layer coating of Corvic obtain.In addition, at this moment, general screen covers in the fabric that mesh is arranged of factor less than 1000 with among the fiber construct S0, and the resin of the light shield layer of fabric also is immersed in the another side, is difficult to only realize in a side application of resin.
On the other hand, when the polyester film lamination process that will form light shield layer S1 and reflection layer S2 is to fiber construct S0, utilize planar metal, paper and/or rubber rollers, the roller of a side under 30-220 ℃, is carried out crimping and comes lamination under the condition more than the contact pressure 2kg/cm.
In addition, reflection layer S2 also can anchor at spherical inorganic particulate on the cloth and silk surface and form.When anchoring at spherical inorganic particulate on the cloth and silk, the coating machine that the usefulness such as polyurethane resin, acrylic resin that will contain this particle of 15-75 weight % have the 1-2 slit doubly of spherical inorganic particulate particle diameter applies, and is then dry down and come set 140-210 ℃ of following heat treatment at 100-150 ℃.Perhaps, also the resin liquid that contains spherical inorganic particulate can be sprayed, but need evenly disperse, thereby spherical inorganic particulate exists in the superiors.
And, by not forming reflection layer S2 at least, preferably not forming on the face of light shield layer S1 and reflection layer S2 exciter is set, use as the one-piece type loud speaker of screen.Exciter is preferably the exciter that comprises magnetic circuit and voice coil loudspeaker voice coil.
In addition,, perhaps strain the bottom, perhaps be fixed on the framework etc., apply suitable tension force and use, will produce the sound of telepresenc like this, so be more preferably by the top of screen being fixed and being loaded onto load in the bottom.At this moment, the tension force that vertical (the weight direction) of screen measured is preferably more than the 0.5kg/m, more preferably 1-5kg/m.
