LOW G-SENSITIVITY CRYSTAL RESONATOR

Abstract: a crystal resonator includes a crystal plate and an electrode set. the crystal plate includes a first vibration section and a second vibration section arranged along an oscillating direction, and exhibits a thickness shear mode. the electrode set includes a first electrode pair disposed on the first vibration section, and a second electrode pair disposed on the second vibration section. the first electrode pair and the second electrode pair are configured to apply the applied voltages with opposite electrical polarities to the first vibration section and the second vibration section, respectively, which causes the first vibration section and the second vibration section to dynamically deform in the thickness shear mode along the oscillating direction, and do out of phase motion with respect to each other.
