Abstract

1. Electrostatic acoustic transducer with two parallel perforated insulating plates (1,2) whose surraces are covered with an electrically conducting layer (3, 4), each of which has a signalling arrangement (5 or 6) for connection with an acoustic frequency signal source, while, between the perforated plates (1, 2), there is fixed a flexible, electrically conducting membrane (7) which is insulated from the electrically conducting layers (3, 4) and has an arrangement (9) for connection with the polarisation voltage source, characterised in that the membrane (7) is electrically conducting with high impedance, that the electrically conducting layers (3, 4) are arranged on the inner surfaces of the perforated plates (1, 2) and that at least one of the electrically conducting layers (3, 4) possesses a high electrical resistance.
