Visual and audio system for theaters

Abstract

A visual and audio system for theaters includes a spherical screen having a desired radius of curvature while having a surface reflectivity of 5-50%, and a projector located at a focal point of the spherical screen. The curvature radius of the spherical screen corresponds to the projection distance of the projector. The image projected from the projector at the focal point of the spherical screen is reflected from the spherical screen in a horizontal direction. Accordingly, viewers can view images projected on the screen corresponding to 5-50 time the brightness of images viewed on conventional theaters screens. Central speakers are arranged at the focal point of the spherical screen, so that viewers perceive the sound effect as coming directly from the spherical screen. This visual and audio system can be effectively used in theaters for stereoscopic moves, theaters for high resolution images, and theaters for viewing of images at a higher brightness such as sports arenas, and restaurant theaters, etc.
