(Physics)
An apparatus for the production of sound by the action of the
actinic, or ultraviolet, rays.
Aerophone
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.
Auxetophone
Auxetophone Aux*e"to*phone, n. [Gr. ? that may be increased +
? sound, voice.]
A pneumatic reproducer for a phonograph, controlled by the
recording stylus on the principle of the relay. It produces
much clearer and louder tones than does the ordinary
vibrating disk reproducer.
Biophotophone
Biophotophone Bi`o*pho"to*phone, n. [Gr. bi`os life + photo +
fwnh` sound, voice.]
An instrument combining a cinematograph and a phonograph so
that the moving figures on the screen are accompanied by the
appropriate sounds.
Electrophone
Electrophone E*lec"tro*phone, n. [Electro- + Gr. ? sound.]
(Physics)
An instrument for producing sound by means of electric
currents.
Gramophone
Gramophone Gram"o*phone, n. [Gr. ? a thing drawn or written
(fr. ? write) + -phone, as in telephone.]
An instrument for recording, preserving, and reproducing
sounds, the record being a tracing of a phonautograph etched
in some solid material. Reproduction is accomplished by means
of a system attached to an elastic diaphragm.
Graphophone

reflected from the knob, the paths or curves corresponding
with the musical notes produced by the vibrations.
KinetophoneKinetophone Ki*ne"to*phone, n. [See Kinetic, Phone.]
A machine combining a kinetoscope and a phonograph
synchronized so as to reproduce a scene and its accompanying
sounds. Metallophone
Metallophone Me*tal"lo*phone, n. [L. metallum metal + Gr. ?

Microphone
Microphone Mi"cro*phone, n. [Micro- + Gr. ? sound, voice: cf.
F. microphone.] (Physics)
An instrument for intensifying and making audible very feeble
sounds. It produces its effects by the changes of intensity
in an electric current, occasioned by the variations in the
contact resistance of conducting bodies, especially of
imperfect conductors, under the action of acoustic
vibrations.
Osteophone
Osteophone Os"te*o*phone, n. [Gr. ? bone + ? voice.]
An instrument for transmission of auditory vibrations through
the bones of the head, so as to be appreciated as sounds by
persons deaf from causes other than those affecting the
nervous apparatus of hearing.

An apparatus for the production of sound by the action of
rays of light. --A. G. Bell.
Pyrophone
Pyrophone Pyr"o*phone, n. [Pyro- + Gr. ? sound.]
A musical instrument in which the tones are produced by
flames of hydrogen, or illuminating gas, burning in tubes of
different sizes and lengths.
Radiophone
Radiophone Ra"di*o*phone, [Radio- + Gr. ? sound.] (Physics)
An apparatus for the production of sound by the action of
luminous or thermal rays. It is essentially the same as the

Thermophone Ther"mo*phone, n. [Thermo- + phone.]
1. A portable form of telethermometer, using a telephone in
connection with a differential thermometer.
2. A telephone involving heat effects, as changes in
temperature (hence in length) due to pulsations of the
line current in a fine wire connected with the receiver
diaphragm.
Topophone
Topophone Top"o*phone, n. [Gr. ? place + Gr. ? sound.]
A double ear trumpet for estimating the direction from which
sounds proceed, esp. for the use of navigators.
