Abstract

PURPOSE: To facilitate an easy adjustment for the spurious frequency in a simple form by providing a groove or hole to adjust the spurious frequency at the amplitude node or belly part of the spurious mode of the mechanical oscillator and thus to ensure the application of the oscillator in a wide frequency range.
CONSTITUTION: The electrostrictive mechanical oscillator consists of tuning bar 1 containing groove 3 for spurious adjustment provided at the center part and electrostrictive elements 2 which are provided at the upper and lower parts of bar 1 to secure the vertical vibration for bar 1. The frequency of the secondary curve can be varied freely for the spurious mode by adjusting depth D of groove 3 in order to secure setting of the spurious outside the range of the using frequency of the oscillator.
