Hedeiaphone Greek?

This stop, whose name is derived from Greek words êdonê (�pleasure�) and fônê (�voice�), is listed only by Wedgwood, who says:

A stop invented by Mr. Hope-Jones, and consisting of metallic plates set into vibration by an alternating current of air. The tone resembled that of gongs. No example exists, but a specimen was exhibited at a lecture delivered by Mr. Hope-Jones at Birkenhead.
