DD273014A1 - METHOD AND DEVICE FOR GENERATING VIBRATIONS - Google Patents

Abstract

The invention can be applied to the generation of vibrations or low-frequency vibrations. The aim of the invention is to provide a reliable method and a largely maintenance-free and low-wear device for generating vibrations. The object of the invention is to guarantee the generation of vibrations by means of a current-carrying coil without the use of coil springs. According to the invention, an alternating voltage is applied to a coil in which there is a vertically movable coil core connected to at least one permanent magnet. A pair of the first permanent magnet arranged second permanent magnet keeps the spool by the opposite pole arrangement in equilibrium. Fig. 1

Method and device for generating vibrations

bi_et the Hrf

The invention can be applied to the generation of vibrations or low-frequency vibrations.

The generation of vibrations by means of a coil and one in the coil? -free moving spool core, which rests on a spiral spring, is known.

Dabcei has the disadvantage that the spring constant changes in the long term due to fatigue, until at last the device is no longer immune to the device.
