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

Abstract: An acoustic passive radiator that controls “rocking mode” vibration. An acoustic passive radiator includes a diaphragm for radiating acoustic energy. The diaphragm has a perimeter portion and a central portion. The perimeter portion is thicker than the central portion. The passive radiator further includes a passive radiator suspension. The suspension includes a skin element encasing the diaphragm. The skin element comprises a surround for physically coupling the passive radiator to an acoustic enclosure, pneumatically sealing the diaphragm and the enclosure.

Abstract: A loudspeaker damper, a manufacturing method thereof, and a loudspeaker, electronic equipment and device using the loudspeaker damper. The damper has flexibility. Therefore, even if a large input is applied and the damper oscillates with a large amplitude, a resin layer provided on the surface of the damper base material is not cracked due to partial interface peeling. Thus, the damper follows such a large amplitude and realizes high input-resistance. This loudspeaker damper material is obtained by impregnating a material with thermosetting resin including 2 to 20 wt % of flexibility imparting agent and heat-curing thereof.

Abstract: A planar magnetic driver includes covering plates that are maintained under tension to form a buckled or curved surface, thereby providing for a larger magnetic gap, and allowing for a larger excursion of the diaphragm and extended lower frequency response. Another aspect of the driver includes a corrugated region along the periphery of the diaphragm, which provides increased internal dampening.
