ABSTRACT:
A tuning fork-type piezoelectric vibrator having electrodes for the excitation formed on the legs of the vibrator body which electrodes extend for at most subsequently half the length of said leg reveals a powerful suppression of the vibration modes of higher orders and substantially no increase in the series resonant impedance in the vibration modes of fundamental frequency.
