Pronunciation: /ˈreznˌādər/


1An apparatus that increases the resonance of a sound, especially a hollow part of a musical instrument.
Example sentences
  • 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.
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.
Example sentences
  • The DFB substrate provides the low threshold operation and wavelength selectable capabilities inherent to resonators based on this approach.
  • 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.
  • 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.
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.
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.
  • The attenuation meters were used to measure the power loss upon sample entry into the measuring resonator.
