ABSTRACT:
A piezoelectric flexural vibrator comprises a circular or polygonal disc of piezoelectric crystal such as quartz, lithium tantalate or lithium niobate which is formed by chemical etching and is supported around its periphery with electrodes on opposite faces comprising a pair of electrodes each of which is divided into two portions of which one is on one face of the disc and the other is on the opposite face of the disc. By reason of its small size -- 25 to 150 microns thick and less than 10mm across -- and its good frequency-temperature characteristics, the vibrator is suitable for use in wristwatches.
