摘要:
There is described an electrostatic film sound transducer, which comprises at least two laterally spaced-apart flat electrodes and at least one flat, electrically conductive layer (7) which is not electrically connected to these flat electrodes and is arranged over the two laterally spaced-apart electrodes. There is additionally described the production of the electrostatic film sound transducer and its use.

The invention relates to foil element constructed from a) an at least partly transparent carrier foil, component A, which comprise at least one cold-stretchable foil material which is provided with optional graphical representations, b) a semitransparent reflecting layer B, c) an at least partly transparent foil comprising at least one cold-stretchable foil material, component C, d) at least one electroluminescent element, component D, applied onto the at least partly transparent foil C, containing the following components da) an at least partly transparent electrode, component DA, db) optionally a first insulating layer, component DB, dc) a layer, component DC, containing at least one luminous substance that is capable of being excited by an electric field, dd) optionally a further insulating layer, component DD, and de) a back electrode, component DE, e) a protective layer, component EA, or a foil, component EB. The invention further relates to the use of the foil element as a decorative panel or cover or a display element for land vehicles, watercraft and aircraft, for forming safety-belt panels or warning-indication panels in land vehicles, watercraft and aircraft, for forming warning-indication panels in buildings, and for forming housing elements for mobile electronic instruments or stationary electronic instruments, or for forming a small or large household appliance or for forming a keyboard.
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.

The invention relates to a loudspeaker designed with a large area having sandwich-like layer structure, consisting of a plurality of conductive and nonconductive layers which form an active sound-radiating loudspeaker surface, having: a first diaphragm sheet (1) coated with an electrically conductive layer (3), a second diaphragm sheet (2) coated with an electrically conductive layer (4) a static high-voltage supply (9), which generates an electric field between the first electrically conductive layer (3) and the second electrically conductive layer (4), an audio source (10) which influences the high-voltage fields between the first electrically conductive layer (3) and the second electrically conductive layer (4) via a capacitor (15). The invention is distinguished in that, with the second electrically conductively coated diaphragm sheet (2), the first electrically conductively coated diaphragm sheet (1) forms a sandwich which extends simply over the active loudspeaker surface, around a first elastic and nonconductive interlayer (5).
