ELECTROSTATIC LOUDSPEAKER SYSTEM

摘要

A electrostatic speaker (ESL) system may include a damping screen placed adjacent an outside surface of at least one of its stators. The damping screen reduces distortion of acoustic output rendered by the speaker's diaphragm. The distortion includes effects of resonance of the diaphragm. A resilient excursion limiter may be placed adjacent an inside surface of at least one of the stators to prevent contact of the diaphragm with the stator. A conductive portion of the diaphragm may be printed with a conductive ink layer that includes conductive nanofibers. The speaker system may include a dipole-radiating ESL element, an unbaffled or partially baffled dynamic speaker and a baffled monopole-radiating dynamic speaker (subwoofer), all essentially co- planar. The unbaffled or partially baffled dynamic speaker provides a smooth transition in sound between the dipole-radiating ESL element and the monopole-radiating subwoofer. The ESL system may include two or more invertedly-driven ESL elements of different sizes, each element handling a different range of frequencies.
