Bearing these facts in mind, it makes sense why plasma speakers have not caught on.

On a smaller scale the same effect can be reproduced using a flyback transformer circuit. By controlling the frequency of the arc’s shockwave it is possible to accurately reproduce music. The video below is an example of such a circuit. In the video, the fidelity of the arc speaker is quite surprising. In fact, arc speakers are superior for accurate sound reproduction when compared to regular speakers. Conventional speakers generate sound by vibrating a conical structure connected to a magnet. The inertia of the cone resists these vibrations to some degree. This means, by the nature of their design, regular speakers have trouble reproducing some sounds without distorting. Plasma arc speakers on the other hand do not suffer from such a draw back. The truth is there are some major limitations holding the technology back. First off plasma speakers need high voltages to operate. This is potentially dangerous and eats up a lot of energy. Furthermore to increase the volume of a plasma speaker the arc needs to be longer, requiring even higher voltages.

Their design relies on the quieter glow discharge mode instead of the more common arc and corona discharges. However, the operation of such speakers requires a continuous supply of helium. To make the plasma speaker a more widely available product, ExcelPhysics, a Seattle-based company, and Images Scientific Instruments, a New York-based company, both offered their variant of the plasma speaker as a DIY kit. Plasma speakers or ionophores are loudspeakers that vary 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. It creates the compression waves in the air that listeners perceive as sound. Tweeters made from plasma arcs have a major advantage – no resonance or transient problems. Most audiophiles know that the lighter the material used in a speaker, the faster the response can be. The base for plasma arc speakers, also known as ionophones, was invented by William Duddeles in 1900. The technique is an evolution of William Duddell's "singing arc" of 1900 and an innovation related to ion thruster spacecraft propulsion. William found that varying the voltage to the arc changed the sound produced.

The plasma speaker is a device that can turn an auxiliary or Bluetooth signal into a beam of plasma! This beam of plasma can expand and contract the air around it to create sound waves. This display offers both Bluetooth and auxiliary connections to play any music or sounds you want! It also has an adjustable arc control knob for controlling the density and quality of the plasma arc.

Plasma Arc Speaker What is a Plasma Arc Speaker? Plasma is a hot ionized gas that is electrically conductive. The plasma arc speaker creates a plasma arc using a high voltage electrical discharge. When an audio signal is passed through the plasma it causes it to vibrate in sync with the audio signal. The Plasma in turn vibrates the air around it to create sound. The Plasma Arc Speaker has a 3.5mm audio input jack for use with MP3 players, computers, phones, etc.

The technique is a much later development of physics principles demonstrated by William Duddell's "singing arc" of 1900, and Hermann Theodor Simon published the same phenomenon in 1898. The term ionophone was used by Dr. Siegfried Klein who developed a plasma tweeter that was licensed for commercial production by DuKane with the Ionovac and Fane Acoustics with the Ionofane in the late 1940s and 1950s. Plasma speakers or ionophones are a form of loudspeaker which varies air pressure via an electrical plasma instead of a solid diaphragm. The plasma arc heats the surrounding air causing it to expand. Varying the electrical signal that drives the plasma and connected to the output of an audio ... Plasma speaker designs ionize ambient air which contains the gases nitrogen and oxygen. In an intense electrical field these gases can produce reactive by-products, and in closed rooms these can reach a hazardous level. To make the plasma speaker a more widely available product, ExcelPhysics, a Seattle-based company, and Images Scientific Instruments, a New York-based company, both offered their own variant of the plasma speaker as a DIY kit. The ExcelPhysics variant used a flyback transformer to step up voltage, a 555 timing chip to provide modulation and a 44 kHz carrier signal, and an audio amplifier. A flame speaker uses a modulated flame for the driver and could be considered related to the plasma loudspeaker. This was explored using the combustion of natural gas or candles to produce a plasma through which current is then passed. These combustion designs do not require high voltages to generate a plasma field, but there has been no commercial products using them.
