phonics See ACOUSTICS, 1.
phonocardiogram The record made by a PHONO-
CARDIOGRAPH.
phonocardiograph An instrument that makes a
graphic record of heart sounds.
phono cartridge The vibration-to-electricity transducer
(pickup) of a phonograph; it is actuated by
the stylus (needle). Common types are ceramic,
variable-inductance, and variable-reluctance. See
PHONOGRAPH and PHONOGRAPH DISC.
phonocatheter A microphone that can be inserted
into the body for the purpose of listening to the
functions of internal organs.
phonograph A device for reproducing sound
recorded on disc. It consists of a turntable, an
amplifier, and one or more speakers.
phonograph cartridge See PHONO CARTRIDGE.
phonograph disc A thin, lightweight disc, usually
made of vinyl or similar plastic, on which audiofrequency
signals are recorded as irregularities in
a spiral groove. In reproduction, these irregularities
cause vibration in a PHONO CARTRIDGE as
the turntable rotates.
phonograph oscillator See PHONO OSCILLATOR.
phono jack Also called RCA jack. A jack similar to
a PHONE JACK, designed especially for the quick
connection and disconnection of coaxial cables
used with audio and low-frequency devices.
phonon A unit of energy resulting from vibration,
as of a piezoelectric crystal.
phono oscillator A small radio-frequency (RF) oscillator
modulated by the audio-frequency (AF)
voltage from a phonograph. The modulated RF
signal is picked up by a remote radio receiver
(usually in the same room), and the sound is reproduced
through a loudspeaker connected to
the receiver.
phono plug Also called RCA plug. A plug similar to
a PHONE PLUG, designed especially for the quick
connection and disconnection of coaxial cables
used with audio and low-frequency devices.
phono plug
phonoreception The hearing of high-frequency
sounds.
phonorecord A PHONOGRAPH disc.
phonoselectroscope A special type of stethoscope,
in which the main heartbeat is attenuated. This
makes abnormal sounds more audible. The device
can be adjusted in various ways to listen for
abnormalities characteristic of various heart diseases.
phosphor A substance that glows when an electron
beam strikes it. Such a substance is used as
a coating on the screens of cathode-ray tubes.

phosphor bronze A form of bronze whose elasticity,
hardness, and toughness have been greatly
improved by the addition of phosphorus. The
metal is used for brushes, springs, switch blades,
and contacts.
phosphor copper An alloy of copper and phosphorus
used in the manufacture of PHOSPHOR
BRONZE.
