Definition of resonator in English:



  • 1An apparatus that increases the resonance of a sound, especially a hollow part of a musical instrument.

    • ‘The bridge rests on a taut membrane which covers the resonator.’
    • ‘Other instruments used included rattles, whistles, flutes, mouth harps, and stringed-instruments constructed with a bow and resonator.’
    • ‘One of the most important skills to be learnt is the adjustment of the resonators to produce different vocal tone-colours, according to the mood and emotional content of the music.’
    • ‘Jodi plays an infectious blend of folk/soul/reggae with her acoustic, slide, resonator and electric guitars and mandolin.’
    1. 1.1 A musical or scientific instrument responding to a single sound or note, used for detecting it when it occurs in combination with other sounds.
      • ‘The mechanical resonator's response over the frequency range depends on various characteristics of the liquid being tested, such as the temperature, viscosity, and other physical properties.’
      • ‘The frequency of nanomechanical resonators is generally determined by reflecting a laser off the resonator.’
      • ‘A combination of Helmholtz resonators on the back wall and absorbers in the ceiling help control the low frequencies.’
      • ‘Use Helmholtz resonators, diaphragmatic absorbers, or plenum absorbers for large rooms having reflective surfaces and in need of speech intelligibility.’
      • ‘The central component of the frequency standard or oscillator is a resonator that vibrates or oscillates with a well-defined frequency when excited.’
    2. 1.2Physics A device that displays electrical resonance, especially one used for the detection of radio waves.
      • ‘A quartz crystal resonator depends on the piezo-electric effect to work. This effect converts a mechanical stress in a crystal to a voltage and vice versa.’
      • ‘The resonator assembly includes a first electrode held in contact with the base layer, a second electrode, and a piezoelectric layer held between the first and the second electrodes.’
      • ‘The DFB substrate provides the low threshold operation and wavelength selectable capabilities inherent to resonators based on this approach.’
    3. 1.3Physics A hollow enclosure with conducting walls capable of containing electromagnetic fields having particular frequencies of oscillation and exchanging electrical energy with them, used to detect or amplify microwaves.
      • ‘The attenuation meters were used to measure the power loss upon sample entry into the measuring resonator.’
      • ‘The method and apparatus includes at least one resonator placed in proximity to a electrodynamic profile and exciting within said resonator an alternating electromagnetic field.’
      • ‘Traditional microwave sources remove the competition by using a resonator, which amplifies only the desired frequency.’
