Abstract

Det er beskrevet en elektrostatisk høyttaler der membraner og statorer har ladninger av samme polaritet. Det er dermed mulig for store krefter å arbeide i høyttaleren uten risiko for overslag mellom stator og membran. Høyttaleren har to membraner (19, 20), hver har en tilsvarende stator (2, 9) formet som et gitter eller liknende laget av et elektrisk ledende materiale. De to membranene er parallelle med hverandre og føyd sammen ved et fast, hardt eller stivt materiale (6). Membranene (19, 20) og statorer (2, 9) av et par har alltid samme potensiale og frastøter hverandre med ei kraft som varierer når potensialet varierer.An electrostatic speaker is described in which membranes and stators have charges of the same polarity. Thus, it is possible for large forces to work in the speaker without the risk of an overshoot between the stator and diaphragm. The speaker has two diaphragms (19, 20), each having a corresponding stator (2, 9) shaped like a grid or similar made of an electrically conductive material. The two membranes are parallel to each other and joined together by a solid, hard or rigid material (6). The diaphragms (19, 20) and stators (2, 9) of a pair always have the same potential and repel each other with a force that varies as the potential varies.
