LOW ACOUSTIC MAGNETIC MOUSE SCROLL WHEEL
This abstract first appeared for US patent application 20250004580 titled 'LOW ACOUSTIC MAGNETIC MOUSE SCROLL WHEEL
Original Abstract Submitted
an information handling system peripheral mouse accepts scroll inputs at a scroll wheel extending from the upper surface of the mouse. the scroll wheel rotates about an axis and has a geared wheel core with peaks and valleys that rotate past a magnet, such as a halbach magnet. the geared wheel core interacts with a magnetic field of the halbach magnet so that magnetic flux resistance to rotation varies based upon the distance between the peaks and valleys to the magnetic field. measuring changes in current at the geared wheel core related to changes in the magnetic field as the scroll wheel rotates provides an indication of wheel rotation, such as by spikes of current as the peaks pass the halbach magnet.
