Abstract

Patente de Inveção: <B>"TELAS DE VìDEO QUE INCORPORAM ALTO-FALANTES"<D>. Tela de vídeo (32), por exemplo uma tela de projeção, que compreende um painel apresentando uma superfícei de reflexão de luz, caracterizada pelo fato de que a tela é um alto-falante de irradiador acústico de modo distribuído que possui um transdutor (9) montado totalmente e exclusivamente no mesmo para vibrar o irradiador de modo a fazer com que ele ressoe para prover uma saída acústica.Patent of Invention: <B> "VIDEO SCREENS THAT INCORPORATE SPEAKERS" <D>. Video screen (32), for example a projection screen, which comprises a panel showing a light reflection surface, characterized by the fact that the screen is a distributed acoustic radiator speaker that has a transducer (9 ) totally and exclusively mounted on it to vibrate the radiator in order to make it resonate to provide an acoustic output.
