Abstract

The vibrating body uses magnetic forces between on the one hand a contact-free, rotating or otherwise periodically varying driving system, and on the other hand a ferromagnetic or electro-dynamically acting systems of magnets or induction coils activating the vibration body and integrated in it. The vibrating body in its entirety is formed as a shell body open at one end and closed at the other, axially composed of two sections, of which the section (1), which faces towards the open end, has a rigid cover part extended in a axis direction. The section which has the closed end consists of an elastic plate (2) flat in the rest position, with radial extension at right-angles to the axis (4) and with its central point fixed. The plate is arranged to permit periodical bending in the axial direction.
