Abstract
A vibrating reed includes a base; and a vibration arm section formed so as to protrude from this base wherein a through groove is formed in the vibration arm section, and a rigidity reinforcing section is provided in the through groove, and thus the frequency is not decreased and the CI value is not increased.
Claims8
A vibrating reed comprising:
- a mounting base for mounting the vibrating reed to an object;
- an elongated vibration arm formed so as to protrude from a fixed end at the base to a free end spaced apart from the base;
- at least one elongated through groove formed on said vibration arm;
- and
- a rigidity reinforcing member spanning the through groove.

A vibrating reed comprising:
- a base;
- and
- a vibration arm section formed so as to protrude from the base, wherein a through groove is formed in said vibration arm section, and a rigidity reinforcing section is provided in the through groove;
- wherein said rigidity reinforcing section further comprises a coupling section formed so as to span said through groove;
- wherein said through groove has longer sides and shorter sides, and said coupling section is a side bar which is coupled so as to span said longer sides;
- wherein a thickness of said side bar is shorter than a depth of said through groove;
- and
- wherein said side bar further comprises a half etched side bar which is shorter than the depth of said through groove.
