ABSTRACT:
A piezoelectric coupled mode turning fork using the fundamental vibration of a flexural mode coupled with the fundamental mode of torsion. The fundamental frequency of the torsional mode is adjusted by masses near the side edges of the tine tips, and the fundamental frequency of the flexural mode being adjusted by masses near the center of the tine tips which are nodes of the fundamental torsional mode.
