Abstract
Structure for mounting a disc-shaped crystal, having a top and bottom surface, of a crystal resonator includes four attachment pads affixed to the crystal on the bottom surface near the perimeter thereof, four base pads affixed to a base surface, and four generally elongate parallel support elements, each extending from a different one of the base pads to a different one of the attachment pads to support the crystal. The support elements are generally longitudinally rigid and laterally elastic so that lateral movement of the crystal may take place without torque being applied to either the pads or the crystal. In other words, when the crystal is moved sideways, the plane of the crystal remains generally parallel with the previous plane occupied by the crystal.
