Resonator
(gcide) | Resonator \Res"o*na`tor\ (-n?`t?r), n. [NL. & G.]
1. (Acoustics) Anything which resounds; specifically, a
vessel in the form of a cylinder open at one end, or a
hollow ball of brass with two apertures, so contrived as
to greatly intensify a musical tone by its resonance. It
is used for the study and analysis of complex sounds.
[1913 Webster]
2. Anything that resounds or resonates; specif.:
(a) (Teleg.) An open box for containing a sounder and
designed to concentrate and amplify the sound.
(b) (Elec.) Any of various apparatus for exhibiting or
utilizing the effects of resonance in connection with
open circuits, as a device having an oscillating
circuit which includes a helix of bare copper wire, a
variable number of coils of which can be connected in
circuit with a condenser and spark gap excited with an
induction coil. It is used to create high-frequency
electric brush discharges.
(c) (Wireless Teleg.) The antenna system and other
high-frequency circuits of a receiving apparatus.
