  Aerophone \A"["e]r*o*phone`\, n. [A["e]ro- + Gr. ? voice.]
     (a) A form of combined speaking and ear trumpet.
     (b) An instrument, proposed by Edison, for greatly
         intensifying speech. It consists of a phonograph
         diaphragm so arranged that its action opens and closes
         valves, producing synchronous air blasts sufficient to


         operate a larger diaphragm with greater amplitude of
         vibration.
