PIEZOELECTRIC RESONATOR WITH FREQUENCY CONTROL

摘要

A piezoelectric resonator with frequency control comprises a crystalline element and two exciting electrodes located coaxially relative to the crystalline element, a crystalline element holder and a body with first electrode is fixed stationary relative to the crystalline element, second electrode is fixed to movable armature of a linear electrodynamical drive. The said drive is fixed coaxially to the crystalline element and comprises an inductor winding, a movable armature and a spring; the armature is located on the inductor winding on the side of crystalline element and fixed by the spring to the body.
