Abstract
A knob assembly is provided that includes a knob having a rotatable shaft, a rotatable first circuit board rigidly attached to the rotatable shaft, and a fixed second circuit board positioned near the first circuit board. The first circuit board includes an encoding portion configured to provide positioning data of the knob, and an eccentric rotating mass (ERM) motor mounted to the rotatable, first circuit board with a shaft of the ERM motor perpendicular to the rotatable shaft of the knob. The ERM motor is configured to produce and transfer vibration to the rotatable shaft of the knob. The second circuit board includes a sensor configured to determine a position of the first circuit board and thereby the knob at least in part from the positioning data provided by the encoding portion.
