Abstract

A dial device includes a base, a cover, a column, a magnet, a magnetic sensor and a signal processing circuit. The cover includes a cap portion and a side wall vertically extending from the cap portion. The column surrounded by the wall includes a first end for connecting to the base and a second end for connecting to the cover. The magnet surrounds the column and is disposed on the base or the cover. The magnetic sensor is disposed on a side surface of the column and coupled to the signal processing circuit. When the cover rotates relative to the base, the magnet rotates around the magnetic sensor, and the magnetic field strengths sensed by the magnetic sensor vary. The signal processing circuit determines the relative rotation direction between the cover and the base according to the difference of the magnetic field strengths sensed by the magnetic sensor.

Dependent claims

A dial device, comprising

a base;
a cover comprising a cap portion and a side wall vertically extending from the cap portion;
a column surrounded by the side wall and including a first end for connecting to the base and a second end for connecting to the cover.
one or more magnets surrounding the column and disposed on the base or the cover;
a magnetic sensor disposed on a side surface of the column;
and
a signal processing circuit coupled to the magnetic sensor,
wherein when the cover rotates relative to the base, the one or more magnets will rotate around the column and the magnetic sensor, and the signal processing circuit will sense a plurality of magnetic signals having different values accordingly, and
the signal processing circuit determines a relative rotation direction between the cover and the base according to the plurality of magnetic signals sensed by the magnetic sensor, and outputs a clockwise rotation signal or a counterclockwise rotation signal.
