  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.
            [Webster 1913 Suppl.]

  resonator
      n 1: a hollow chamber whose dimensions allow the resonant
           oscillation of electromagnetic or acoustic waves [syn:
           resonator, 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: resonator, resonant   circuit
         ]
