Abstract
The utility model relates to electronic equipment and a virtual knob thereof. The electronic equipment comprises a knob main body, a processing module, a capacitance digital conversion circuit, a switch array and at least two detection modules, the knob body is a non-movable component protruding from the outer surface of the outer base body, one detection module is located on the side wall of the knob body, the other detection module is located on the side wall of the knob body or the outer surface of the base body, and one detection module is configured to comprise at least three first electrodes. The first electrodes are arranged in the circumferential direction of the knob body to form a partially-closed or fully-closed first discrete array, the other first electrode is configured to comprise electrode units surrounding the circumferential direction of the knob body, and the electrode units and the first discrete array are staggered in the array center axis direction. The capacitance digital conversion circuit is respectively coupled with each electrode through the switch array; the processing module is coupled with the capacitance-to-digital conversion circuit.
