Abstract
Embodiments of the present disclosure are directed to a piezoelectric resonator. The resonator can have a base defining at least a first base portion and a second base portion and two or more vibrating arms projecting from the first base portion, the first vibrating arm being substantially parallel to the second vibrating arm. The resonator can define a generally planar first main surface and a generally planar second main surface defined by the base and the first and second vibrating arms wherein the first main surface is generally parallel to the second main surface. At least one groove can be formed in at least one of the first and second main surfaces of each of the first and second vibrating arms. The resonator can further have at least one vibration isolation arm projecting from the base, the vibration isolation arm being approximately perpendicular to the two or more vibrating arms.
