摘要:
A structure for supporting a vibrator 1 is provided. The structure comprises a substrate 12 and bonding wires 14A, 14B fixed to the substrate 12 and connected with the vibrator 1. The vibrator 1 is supported with the bonding wires so that the vibratctr 1 is not directly contacted with the substrate 12. "fd" and "fw" satisfy the following formula (1). "fd" represents a resonance frequency of a driving vibration mode of the vibrator and "fw" represents a characteristic frequency of a vibration mode of the bonding wire at room temperature. fd / 2 × 1.05 ≦ fw , or , fw ≦ fd / 2 × 0.95

A piezoelectric device comprises a piezoelectric resonator element (10); a lead wire (15A, 15B, 16A, 16B) holding the piezoelectric resonator element (10), one end portion of the lead wire being connected to the piezoelectric resonator element (10); and a support substrate (22) supporting the lead wire (15A, 15B, 16A, 16B), wherein the other end portion of the lead wire (15A, 15B, 16A, 16B) is affixed to a surface of the support substrate (22) that faces away from the resonator element (10).
摘要:
It is provided a supporting structure having a substrate 12 and bonding wires 14A, 14B fixed onto the substrate 12 and connected to a vibrator 1. The substrate 12 has a pair of fixed portions 12a opposing each other and a pair of non-fixed portions 12b opposing each other. The fixed portions 12a and the non-fixed portions 12b together define a through hole 13A in the substrate 12. The vibrator 1 is supported with the bonding wire so that the vibrator 1 is not directly contacted with the substrate 12. The bonding wires 14A, 14B are fitted to the fixed portion 12a and is not fitted to any of the non-fixed portions 12b.

摘要:
Disclosed is a vibrator unit comprising a support section (14) for supporting a vibrator (10) on a substrate (17), the vibrator comprising a drive section (11A,11B) and a detection section (12). The drive section (11A,11B) comprises first and a second parallel rod-shaped drive arms vibrating in a first direction perpendicular to the applied rotation; the detection section (12) comprises a rod-shaped detection arm disposed between and parallel to the first and the second drive arms and detecting the Coriolis force acting in a third direction. The vibrator further comprises a rod-shaped arm supporting section (13) parallel to the first direction, wherein the ends of the arm supporting section are connected to the centers of the first and second drive arms (11A,1B) and the center of the arm supporting section is connected to the center of the detection arm (12). A vibrator supporting mechanism (15A,15B) comprises a first elastic mechanism for supporting the supporting section along the third direction.
