发明名称 SOUND REPRODUCTION SET FOR SCREENS
摘要 In certain loudspeakers, the electromechanical transducer consists of a piezopolymer film. In a new, extremely compact arrangement for this type of loudspeaker, the film (4) is a transparent film and is applied to a television screen (2), the glass pane of a framed picture and the like. This arrangement is particularly suitable for the loudspeaker of a television set (1), which can be controlled by a digital audio signal.
