Abstract:
1. A magnetic oscillation metric controller is comprised of a scrolling wheel mechanism, an expansion base, a dancer, a permanent magnet, and a Hall sensor; the permanent magnet being driven by oscillation displacement to produce changes in magnetic field; a sensor retrieving signals of the changed magnetic field; a pivot being each provided in front and back of the scrolling wheel mechanism; both pivots striding over and respectively pivoted to their locking slots disposed in the front and the back of the expansion base; the dancer extending from either pivot and connected at its below a pendant; a trough being disposed in the pendant to merely accommodate the permanent magnet; the permanent magnet synchronously and laterally oscillating as driven by the scrolling wheel mechanism; and the Hall sensor disposed below the permanent magnet retrieves changed signals of the oscillation to achieve the purpose of control of lateral oscillation.
