Abstract:
A resonator includes a vibrator that performs mechanical vibration, an exciting unit that applies an exciting force to the vibrator, and a modulating unit that modulates a spring property of the vibrator. The vibrator vibrates when the exciting force is applied to the vibrator from the exciting unit. The modulating unit modulates the vibrator according to the exciting force.
