    • 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.
    • 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.
  • 1.1A musical or scientific instrument responding to a single sound or note, used for detecting it when it occurs in combination with other sounds.
    More example sentences
    • 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.
    • 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.
  • 1.2 Physics A device that displays electrical resonance, especially one used for the detection of radio waves.
    More example sentences

  • 1.3 Physics 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.
    More example sentences
    • Traditional microwave sources remove the competition by using a resonator, which amplifies only the desired frequency.
    • 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.
