1924 R. A. Engler U.S. Patent 1,507,884 3/1 I may call my transmitter an ‘ionophone’ or ‘phonia’, one signifies ‘ion speaker’ and the other ‘speaking ion’, because ions are used in all its forms.

2. A kind of loudspeaker that uses the vibrations of a volume of ionized air in place of those of a diaphragm.
