ABSTRACT:
A tubular piezoelectric oscillator having an electroconductive or non-electroconductive tubular casing, the vacuum interior chamber of which receives piezoelectric oscillating element rectangular plate supported at at least one end thereof by an elastic support element for protecting the piezoelectric oscillating element from thermal deformation and impulsive or vibratory force transmitted from the outside. The interior chamber of the tubular casing is maintained in a vacuum condition by a hermetically sealed pipe-like sealing member or members provided at either one or both axially opposite ends of the tubular casing, at which ends are arranged electroconductive members used as electric leads for extracting an electric oscillating signal from the piezoelectric oscillating element.
