Embodiments of the present disclosure relate to a magnetic system, a magnetic system knob, equipment having the magnetic system, and a method for determining movement. The present invention relates toa magnetic knob system (100). The magnetic knob system (100) is provided with a plate (102) having a positioning magnet (106) and a knob (104) having a complementary positioning magnet (106'). The knob (104) is rotatable on the plate (102), and the knob (104) and plate (102) are separable from each other. The knob (104) includes: a vertically movable element (108), and a magnetic detection circuit (110) configured to detect a change in the magnetic field (112) caused by vertical movement of the vertically movable element (108). The invention also relates to a knob (104), equipment having a magnetic knob system (100) and a method (1000).
Description
technical field The example involves a magnetic system. Other examples relate to a knob with a magnetic system and a device with a magnetic system. Still other examples relate to a method for determining movement. Background technique The magnetic system may include a knob and may be configured to detect movement of the knob. The knob may include a magnet that induces a magnetic field. If the knob is moved, eg rotated, the magnetic field moves, rotates respectively according to the movement of the knob. Changes in the magnetic field can be used to detect movement of the knob. Such a magnetic system may be provided in an electronic device, for example a knob may be used as a controller for adjusting the function of the electronic device. A magnetic system may sense rotation of a magnetic knob, for example, by using a magnetic component to detect a corresponding movement of a magnetic field. Depending on the rotation of the knob, eg settings of the electronic device can ...
