ABSTRACT:
A damped piezoelectric ceramic resonator. The resonator is a thin flat plate of piezoelectric ceramic material which has parallel major planar surfaces and is polarized in one direction in such a way that said direction is at an angle of from 0.degree. to 60.degree. with respect to said major surfaces, the thickness dimension of said plate being such as to impart thereto a resonance of vibrations in a thickness-shear mode at a particularly selected frequency higher than one megacycle. Operating electrodes are applied to said major planar surfaces. Vibration damping means is attached tightly to the contour of the edge of said flat plate so as to suppress unwanted resonance vibrations in said flat plate during operating. The vibration damping means is a ring of a rubber material having a hardness from 20 to 70 on the Shore A Scale and is under a tension of 20-500 gm/cm.
