<p>A magnetic vibration or oscillation device has a return structure for lateral metric control consisting of a roller wheel mechanism, an expansion base, a moving part, a permanent magnet, and a Hall sensor. A permanent magnet is driven with the oscillation by the displacement. A sensor receives the signals from the varied magnetic field, the return structure is provided with an elastic bar which is held in place by a rod, and an elastic bar which extends through a guide aperture in the rod, to align this elastic bar according to the moving part and to guide this for checking purposes by the moving part.</p> |
