Abstract

A piezoelectric oscillator in the form of a tuning fork having two arms and being particularly useful as a time standard for timekeeping devices. The arms of the tuning fork which oscillate during operation of the device are decoupled or isolated from a carrier upon which the fork is mounted by two decoupling elements. The tuning fork is provided with electrodes carried by selected surfaces of the arms thereof in various symmetrical arrangements, including axial and central symmetry. One of the decoupling elements is disposed intermediate the arms of the tuning fork and the position at which the electrical connections are made to the electrodes so that the mass of the electrodes does not affect the oscillation of the arms. The piezoelectric oscillator is thus extremely frequency stable, efficient, and relatively uninfluenced by external factors.
