Abstract

See full text

A vibratory structure includes: a vibratory body; piezoelectric elements mounted to a surface of the vibratory body; and resonant circuits configured to operate in response to electrical energy generated by the piezoelectric elements so as to cause a change in a damping characteristic of the vibratory body at a target frequency upon vibration of the vibratory body, and assuming that an axis of the vibratory body in a direction of principal strains is a reference axis, each of the piezoelectric elements is fixed at fixing regions at different locations in the direction of the reference axis.
