Screen knob and electronic equipment

The invention relates to an on-screen knob and electronic equipment, the on-screen knob comprises a knob body and an induction assembly which are respectively located at two sides of a screen, the knob body is provided with a magnetic ring, a plurality of magnetic blocks are sequentially arranged on the magnetic ring along the circumferential direction of the magnetic ring, and the polarities of the adjacent magnetic blocks are opposite; the sensing assembly at least comprises a first linear Hall element, a plurality of second linear Hall elements and a recognition module, the recognition module is used for determining operation of the knob based on the magnetic field intensity obtained by the sensing assembly, and in the reference state of the knob, the first linear Hall element corresponds to the center position between any two adjacent magnetic blocks, and the second linear Hall element corresponds to the center position between any two adjacent magnetic blocks. And the plurality of second linear Hall elem
