The present invention concerns an electrostatic loudspeaker in which the membranes and stators have charges of the same polarity. It is hereby possible for great forces to work in the loudspeaker without causing a risk for sparking-over between stator and membrane. A loudspeaker according to the invention has two membranes (19, 20), each having a corresponding stator (2, 9) shaped as a grid or the like made from electrically conductive material. The two membranes are parallel to each other and joined together by a firm, hard or stiff material (6). Membranes (19, 20) and stators (2, 9) of a pair always have the same potential and repel each other with a force which varies when the potential varies.
La présente invention se rapporte à un haut-parleur électrostatique dans lequel les membranes et les stators ont des charges de même polarité. Il est, de ce fait, possible que les grandes forces agissent dans le haut-parleur sans qu'il y ait risque d'amorçage entre le stator et la membrane. Le haut-parleur de l'invention possède deux membranes (19, 20), chacune ayant un stator correspondant (2, 9) de la forme d'une grille ou autre, conçu dans un matériau électroconducteur. Les deux membranes sont parallèles et réunies de façon à former un matériau résistant, dur ou rigide (6). Les membranes (19, 20) et les stators (2, 9) d'une paire respective ont toujours le même potentiel et ils se repoussent les uns les autres avec une force qui varie lorsque le potentiel varie.
