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. and uses a 12VDC power supply, included.

Kit includes PCB, flyback tranformer, components, plasma tube and enclosure. Kit requires assembly and soldering. Projects develops high voltages to create plasma arc speaker. High voltages are present on pcb and inside plasma tube and builder must exercise proper safty measures and caution when building this circuit and using this project.
