Piezoelectrically driven tuning fork with integral damper member

摘要

The present invention is directed to a tuning fork wherein a damping piece is provided, either integral with said tuning fork vibrator or a separate piece attached thereto, and wherein a damper member is intersected between said damping piece and a housing for accommodating the tuning fork vibrator. Since the (1/2)fO spurious response which is caused in the tuning fork vibrator to be spread within the damping piece is adapted to be absorbed by the damper member, the tuning fork is made smaller in shape.
