发明名称 Piezoelectric vibrating piece with extended supporting arms
摘要 Piezoelectric vibrating pieces are disclosed made of a piezoelectric material to be mounted in a package. A representative piece includes a base formed of a piezoelectric material, having first and second ends, extending between the ends in a length direction, and having a designated width. The piece includes at least a pair of vibrating arms extending in the length direction from one end of the base, and a pair of supporting arms extending partially in a width direction from between the first and second ends of the base. The supporting arms further extend in the length direction outboard of the base and vibrating arms, and include an adhesive region at the tips of the supporting arms. The adhesive regions are used for mounting the piece to a package. Whereas the tips of the supporting arms do not extend beyond the tips of the vibrating arms, the axial length of supporting arms is greater than the length of the vibrating arms.
