Piezoelectric frames and piezoelectric devices comprising same

A piezoelectric frame, comprising:

• a tuning-fork type piezoelectric vibrating piece comprising a base having a first end edge and a second end edge opposite the first end edge, at least a pair of vibrating arms extending in a first longitudinal direction from the first end edge of the base, and at least one excitation electrode situated on the vibrating arms, the piezoelectric vibrating piece extending length and width in a plane in which the piezoelectric vibrating piece has a designated length in the plane from the second end edge of the base in the first longitudinal direction;
• a frame portion situated in the plane in which the frame portion is coupled to and surrounds the tuning-fork type piezoelectric vibrating piece;
• a respective supporting arm extending in the plane laterally from the base and in the first longitudinal direction, outboard of and parallel to the respective vibrating arm;
• and
• a respective connecting portion connecting each supporting arm to the frame portion, each connecting portion extending in the plane from the frame portion to the respective supporting arm in a second direction intersecting the first longitudinal direction, the connecting portions being connected to the frame portion and respective supporting arms at designated locations that are more than 50% of the designated length of the tuning-fork piezoelectric vibrating piece from the second end edge of the base.
