Resonator \Res"o*na`tor\ (-n?`t?r), n. (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.

Resonator \Res"o*na`tor\, n. [NL. & G.]
   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.

resonator
     n 1: a hollow chamber whose dimensions allow the resonant
          oscillation of electromagnetic or acoustic waves [syn: {cavity
          resonator}, {resonating chamber}]
     2: an electrical circuit that combines capacitance and
        inductance in such a way that a periodic electric
        oscillation will reach maximum amplitude [syn: {resonant
        circuit}]
     3: any system that resonates
