Author: You can play music on it. No, seriously. Check out this plasma tweeter:
This is a prototype of a FM modulated plasma arc speaker / tweeter. Currently in the process of making an improved vertical discharge setup, using tungsten-tipped electrodes. Hopefully, this will stop the plasma hopping about & causing unwanted distortion…
That purple plasma spark you see there is about 60,000 volts.

is the song we’re hearing coming from the plasma itself? (ie producing sound waves??)

You lost me at modulated. But I like anything that plays music, so bring on the plasma I say.
“FM modulated plasma arc speaker / tweeter”
“improved vertical discharge setup”
Must be some kind of secret geek speak.

If it helps, I have no idea what he’s talking about, either. Ooooh! Purty!
