Electromagnetic vibrator with tensile stress clamped leaf springs - with two weights coupled by springs and tuned to their natural frequency

摘要

Electro-magnetic vibrator consisting of two weights coupled by a spring system and tuned to their natural frequency and an exciter magnet system, consisting of two sections with synchronised oscillation. The spring system consists of leaf springs and is divided into sectional units (3a, 3b). The two weight sections (1a, 1b) attached to the ends of the leaf spring units (3a, 3b) are positioned between the sectional units (3a, 3b).
