Abstract
Abstract The present invention concerns means for generating periodical mechanical vibrations by means of electric energy and deals with a greatly simplified and efficacious swing system which produces mechanical vibratory movements, which system dispenses with any active elements or components except for an energy or current source or cell, the energy losses produced by ohmic resistances in the system being reduced to a minimum and resulting in a high degree of efficiency, reliability, and accurate performance. Three electrodes are arranged to constitute a mechanical oscillating or swinging arrangement of which one electrode is resiliently supported and is capable of flexing and swinging along a predetermined length of an oscillating course and in a direction toward and away from the other electrodes, a charge compensation in condenser fashion occurring when the one electrode approaches one of the other two electrodes closely enough within an electric field established between said electrodes. In the position of rest said electrodes are sufficiently remote or spaced from each other but are aligned with their frontal faces confronting each other.
