Patent ID: 7148609

Claim:
A structure for supporting a vibrator comprising a terminal for electrical connection, a signal electrode for driving, a ground electrode for driving, a signal electrode for detection, and a ground electrode for detection, said structure comprising: a substrate; a frame provided on said substrate; a center hole formed inside of said frame; a bonding wire supported on a surface of said substrate, connected to said vibrator and fixed to said frame; wherein said vibrator is supported with said bonding wire so that said vibrator does not directly contact said substrate, at least a part of said vibrator is positioned over said center hole and said bonding wire is electrically connected with said terminal, and wherein the resonance frequency “fr” of said supporting structure, the driving frequency “fd” for said vibrator and the detuning “Δf” satisfy the following formula: 1.1 ·Δf≦fr≦ 0.9 ·fd.
