PIEZOELECTRIC VIBRATING PIECES, PIEZOELECTRIC DEVICES, AND METHODS FOR MANUFACTURING SAME

摘要

Piezoelectric vibrating pieces are disclosed that include a base, a pair of vibrating arms, and a pair of supporting arms. The base is fabricated of piezoelectric material. The vibrating arms extend straight from the base in a designated longitudinal direction and having a first thickness. A respective supporting arm extends straight from the base and outboard of each vibrating arm in the designated longitudinal direction. Each supporting arm includes at least a respective second region that has second thickness different from the first thickness.
