ABSTRACT:
A hermetically sealed quartz crystal vibrator assembly having a flexible mounting plate for mounting a flexural mode quartz crystal vibrator adapted to vibrate in a first vibratory direction on a reference member. The mounting plate includes a first portion for supporting the vibrator and a second portion for coupling to the reference member. The mounting plate further includes a resilient portion between the first and second portions, the resilient portion being adapted to vibrate in the first vibratory direction and to further vibrate in a vibratory direction defining an angle of about 90.degree. with respect to the first vibratory direction. The resilient portion of the plate includes a stepwise bend to thereby define a gap between the vibrator and the resilient portion of the mounting plate overlapping the vibrator.
