VIBRATION TRANSDUCER Russian patent published in 1995 - IPC

FIELD: design of reverse counters. SUBSTANCE: device has electromechanical transducer, which is designed as piezoelectric elements located between passive base and upper cover plate, concentrator of pitching and rotational oscillations, and rotor which engages with concentrator. Concentrator is attached to upper cover plate by elastic connection of at least three connecting ribs. Concentrator is attached to passive base by elastic connection of torsion having at least two rods. Said rods are positioned at angle with respect to vertical axis and are stretched to value given in invention specification. stiffness of connecting ribs along axis of oscillations of piezoelectric elements is much greater than stiffness of torsion along this axis. Stiffness of connecting ribs along orthogonal axis conforms to condition of equality of resonant frequency of piezoelectric elements with resonant frequency of connecting ribs oscillations along this axis. EFFECT: increased functional capabilities. 9 dwg
