Abstract
An electrostatic loudspeaker (ESL) assembly providing curvature in two directions for improved dispersion of sound waves. The ESL comprises at least one stator panel, a flexible diaphragm and a spacer that impedes contact between the stator panel and the diaphragm. The stator is formed from a material that comprises an array of apertures. Furthermore, the material can be annealed. The material temper, along with the aperture geometry and patter, affect the stretchability of the material. The two-axis curved structure enables a compact form of ESL to be realized, including bookshelf type loudspeakers whereas all known commercial units are comparable in height to that of a human listener. The individual curved ESL panels can also be readily combined to create larger transducer assemblies including omni-directional units.
