Abstract
Crystal resonator with low acceleration sensitivity includes a piezoelectric quartz crystal, support structure for holding the crystal and a signal source for causing the crystal to resonate with an active region of vibration. The resonator is modified, if need be, to control (generally reduce) the gamma vector which is a measure of the acceleration senstivity. This may be done by adding mass, removing mass, or both adding and removing mass, all in order to move or change the shape of the active region of vibration and thereby reduce the gamma vector.
