resonator

A resonating system.

A hollow chamber or cavity with dimensions chosen to permit internal resonant oscillation of electromagnetic or acoustical waves of specific frequencies.

A resonant circuit.

An acoustical instrument used in the analysis of sounds, consisting of a chamber so formed as to respond sympathetically to some particular tone. It is used especially to detect the presence of that tone in a compound sound.

In electricity, an instrument devised by Hertz for detecting the existence of waves of electrical disturbance.

In electricity: A circuit the dimensions, inductance, and capacity of which are such that it is in syntonism with some similar circuit. Electric oscillations in the one will then set up oscillations of the same frequency in the other, even at a distance.

In anatomy, the parts above the larynx which act as a resonance-box in voice-production.

A general name for such musical instruments as consist essentially of a hollow body or globe, the confined air of which is thrown into vibration by blowing upon the edge of a hole in its side, while the pitch is controlled by other holes stopped by the fingers, such as the clay whistles and ocarinas found in various parts of the world.

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.

Anything that resounds or resonates
