ABSTRACT:
A tuning fork-shaped quartz oscillator comprises a U-shaped quartz oscillator body which comprises of a pair of vibration arms having a rectangular cross section and a base connecting the vibration arms at one end. Four excitation electrodes are provided respectively on the four sides of each vibration arm, each electrode having a portion laid on two adjacent sides. The oscillator further comprises connecting means including a first input terminal and a second input terminal which supply drive voltage to the excitation electrodes so that the vibration arms keep vibrating in opposite phase relation in both a bending mode and a twisting mode.
