any chance of using a burning flame to produce plasma for a plasma tweeter? or, if a flame is conductive, could you run an audio signal through it, while it is inside a magnetic gap like a ribbon driver?
ionized air has been used a few times. Google on jonophane.
There is also a homebuilt tweeter at http://www.plasmatweeter.de/

Sure, not a problem. You can run a flame (MAPP, Propane..etc) seed it with a salt, something like KCl (aq). Put a couple of electrodes in the reducing part of the flame (proximal and distal)... add 400 - 600 VDC polarizing voltage and modulate with your favorite tunes. Low frequency will be determined by the length of the seeded flame. Another one of those instances where bigger is better!
Heat and HV, beware

i chouldnt think so with something like salt. both chlorine and sodium are quite reactive. i think the biggest danger is that associated with an open flame. I wonder if i just use a sooty flame, the carbon atoms might work. are they ionized or just glowing?
Have fun with your friends - do it with a campfire!
Use some stainless steel electrodes... pipe in some Jimi Hendrix and go for it!

Soot laden flame will not be hot enough!!!! Soot will not give you ions... ya needs ions.
Stainless steel electrodes won't last through a single Jimmy Hendrix, cut. Best get yourself some tungsten (tig welding electrodes), they're cheap enough. Alternately you could use carbon arc gouging electrodes.
I've a very old text book (pre- 1900) on electrical machines; which credits Ben Franklin with a talking flame. Only reference I've seen to such a thing associated with ol Ben. I thought he had used all his "luck" up on the kite fiasco.

Hoot Mon!
Ya das gudden Tongueston!
😀
When that nice oak or maple camfire is all red hot embers with blue flame, betcha it will work ok!
And, iirc ya can do it with a bunsen burner flame, i think with the seeding...
