Abstract

"SISTEMA DE PROJEçãO DE OBRAS CINEMATOGRáFICAS OU DIGITAIS SONORAS." A presente invenção se refere a um sistema para a projeção de obras cinematográficas ou digitais, com som, tendo pelo menos um canal de som. O sistema compreende uma tela (4) e, para o referido canal de som, pelo menos um woofer (6) e pelo menos um transdutor de médios/agudos (7). A tela é uma tela não perfurada. O alto-falante de médios/agudos é um transdutor sonoro plano chapado contra a tela, do seu lado posterior com relação à direção da projeção. Um transdutor de extremos agudos (8) é posicionado na periferia da tela.
