The structure and performance of the electrostatic loudspeaker has been well described in many references and will not be repeated here. The early work of Walker gave a good description that remains relevant [1], and later described a version with better diurectivity [2]. The more recent work of Mellow gives more recent devellopments and is summarized in a recent book chapter [3]. The Simscape model include here follows the work of Mellow and calculates the electrical behavior an dacoustical radiation from a circular diaphragm that is 14 cm in diameter. That Simscape model is shown in Fig. 1.
