Abstract

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.
