摘要:
A loudspeaker designed with a large area having sandwich-like layer structure includes a plurality of conductive and nonconductive layers which form an active sound-radiating loudspeaker surface. The plurality of conductive and nonconductive layers include a first diaphragm sheet coated with an electrically conductive layer, a second diaphragm sheet coated with an electrically conductive layer, a static high-voltage supply, which generates an electric field between the first electrically conductive layer and the second electrically conductive layer, and an audio source which influences the high-voltage fields between the first electrically conductive layer and the second electrically conductive layer via a capacitor. The invention is distinguished in that, with the second electrically conductively coated diaphragm sheet, the first electrically conductively coated diaphragm sheet forms a sandwich which extends simply over the active loudspeaker surface, around a first elastic and nonconductive interlayer.
