1. a device or object that vibrates in response to sound waves or produces resonant sound
Usage: physics; music
2. a hollow chamber or cavity that reinforces sound by resonance
Usage: acoustics

Examples

• The guitar’s body acts as a resonator to amplify the strings’ vibrations.
• Scientists used a resonator to study sound wave patterns.
• The violin’s resonator gives it its distinctive rich tone.
• The acoustic resonator in the speaker enhanced the bass frequencies.
• Engineers designed a resonator to filter specific radio frequencies.
• The resonator in the wind instrument determines its pitch range.
