Stiffness-enhanced surface-mounted piezoelectric devices

摘要

Surface-mounted piezoelectric devices are disclosed, of which an exemplary device includes a tuning-fork type piezoelectric vibrating piece having a base portion and a pair of vibrating arms extending from the base portion. The device includes a package defined by a wall. The package includes a cavity accommodating the tuning-fork type piezoelectric vibrating piece and at least one columnar body situated between the vibrating arms in the cavity.
