Abstract:
1. An improved electrostatic speaker system comprising: a) at least one electrostatic speaker coupled to an AC voltage source and including a front and back stator plate positioned in a parallel relationship with respect to one another and having a multitude of bores formed in each stator; b) an electrically conductive flexible film membrane positioned intermediately parallel to the front and back stator plates, the film membrane vibrating forward and backward between the front and back stator in response to a high voltage AC audio signal applied to the film membrane from an audio power transformer coupled to an audio amplifier providing an audio signal, the bores formed in the stators allowing air to pass through each stator when the film is vibrating; and c) the front and back stators receiving a static DC bias voltage rectified from the AC voltage source causing the film membrane to vibrate in response to opposite charges between the high voltage AC audio signal on the film membrane and the static DC bias voltage on the stators, reproducing the audio signal provided by the audio amplifier.
