An electrostatic transducer has three basic components - stators, diaphragm, and spars (spacers) - assembled as a sandwich. The diaphragm is an ultra light plastic film, impregnated with an electrically conductive material and stretched taut between the two stators, which are perforated steel sheets coated with an insulator. When the speaker is operating, the diaphragm is charged to a fixed positive voltage by a high-voltage power supply, creating a strong electrostatic field around it.
