Audio Systems: Nitride for direct electric-to-sonic conversion -- will it work?, nitrogen ions, nitrogen gas

Question
Hi:

I am thinking of a way to directly convert electric energy into sonic energy -- for audio playback. The loudspeaker passes electric current through ionizied nitrogen -- in the form of nitride ions.

If my music room had nitride ions [nitrogen ions with 3 extra electrons] in place of nitrogen gas, would it be easier to directly convert electricity into vibrations of air molecules? My guess is yes. Of all the gases on the earth's atmosphere, nitrogen is the most abundant -- 78%. Chances are, my music room currently contains 78% of electrically-neutral nitrogen, with about 21% oxygen, 1% H20 vapor, and traces of CO2 and other gases.

If the room with my audio equipment had 78% nitride gas [instead of nitrogen gas], then it would be significantly easier to make those nitride molecules vibrates analogously to an AC electric current passing through the air containing those nitride ions. Right?

Nitride ions are negative so they will try to move away from the electrons. As they attempt, they [I think] will vibrate similarly to the  way the electron current oscillates.

I chose nitride ions, because nitrogen is the least reactive of all the commons gases in the earth's atmosphere. Oxygen, hydrogen, and others are not so calm in their ionic states. For example, oxygen will convert to ozone when ionized.

Do you think this would work out? Will it efficiently playback the music?


Thanks,

Green

Answer
My background certainly is in electronics. I haven't delved into theory and physics since I was in school in the 60's. It sounds like an interesting R&D experiment. I'm not sure I would want to breath the atmosphere with a higher level of Nitride ions. Have you tried to do this or is it a dream of your? Whether or not it works is certainly something I'd be interested in hearing about. I know of no one else performing this kind of experiment. Good luck.
