. The ion loudspeaker, on the other hand, works massless by changing the air volume through temperature changes. In the ion loud
speaker, thesound waves
are transmitted by a momentary change in volume as the air molecules transport this change in volume.Technically, an ion or plasma loudspeaker is an RF oscillator whose output power causes air ionization
This ionization is modulated with the audio signal, making it stronger and weaker. A stronger ionization produces a higher temperature and thus a higher sound pressure.
