The Technology
Extremely Ingenious Engineering demonstrates a novel method for generating a plasma which responds to audio signal. This technology uses resonant transformers to establish the plasma combined with a novel method for imposing the audio modulation.

• Plasma generated directly from air.
• No additional gases required.
• Plasma responds visually to the audio signal.
• Wireless connectivity possible for multiple speakers.
  

How It Works
Resonant Transformers create a high voltage which results in generation of a plasma, as in a 'conventional' plasma speaker. In EIE’s speakers, the plasma arc is generated by corona effect, so only one electrode is used.

The resonant transformers are driven at frequencies higher than the audio response, which enables imposition of the audio signal. These transformers then produce a high voltage that is imposed upon the speaker electrode. Corona, or ionization of the air, produces a plasma controlled by the audio signal. It acts as a carrier wave, upon which the audio signal rides and is transferred to the free-space plasma.

• Speaker power on the order of hundreds of watts is possible!
• A novel arrangement of high-power Insulated Gate Bipolar Transistors (IGBTs) makes this high power audio response possible.
• Visual response of the plasma to the audio signal occurs. Ionization of the surrounding air occurs (corona) making a white-blue arc.
• The plasma forks and moves with the beat!
  

Wireless Connection
In conjunction with our Q-Bridge Wireless Power and Data Transmission, we are working to connect these speakers wirelessly via the electromagnetic near field generated by the speaker.

We envision driving one speaker with an audio signal with paired speakers nearby that emulate that signal. The audio signal couples through free-space to nearby resonant transformer plasma speakers.
