- Plasma_speaker abstract "Plasma speakers are a form of loudspeaker which varies air pressure via a high-energy electrical plasma instead of a solid diaphragm. Connected to the output of an audio amplifier, plasma speakers vary the size of a plasma glow discharge, corona discharge or electric arc which then acts as a massless radiating element, creating the compression waves in air that listeners perceive as sound. The technique is an evolution of William Duddell's "singing arc" of 1900, and an innovation related to ion thruster spacecraft propulsion The effect takes advantage of two unique principles. Firstly, ionization of gases causes their electrical resistance to drop significantly, making them extremely efficient conductors, which allows them to vibrate sympathetically with magnetic fields. Secondly, the involved plasma, itself a field of ions, has a relatively negligible mass. Thus as current frequency varies, more-resistant air remains mechanically coupled with and is driven by vibration of the more conductive and essentially massless plasma, radiating a potentially ideal reproduction of the sound source.Conventional loudspeaker transducer designs use input electrical frequencies to vibrate a significant mass: This driver is coupled to a stiff plastic composite speaker cone - a diaphragm which pushes air at respective frequencies. But the inertia inherent in its mass resists acceleration- and all changes in cone position. Additionally, speaker cones will eventually suffer tensile fatigue from the repeated shaking of sonic vibration.Thus conventional speaker output, or the fidelity of the device, is distorted by physical limitations inherent in its design. These distortions have long been the limiting factor in commercial reproduction of strong high frequencies. To a lesser extent square wave characteristics are also problematic; the reproduction of square waves most stress a speaker cone. In a plasma speaker, as member of the family of massless speakers, these limitations do not exist. The low-inertia driver has exceptional transient response over other designs. The result is an even, linear output accurate even at extreme frequencies beyond any audible range. Such speakers are notable for accuracy and clarity, but not tremendous power because plasmas composed of tiny particles are unable to move large volumes of air. So these designs are more effective as tweeters.".
