Input device and electronic device

An input device, comprising:

• a support structure, wherein one end of the support structure is fixed to a substrate;
• a cover, wherein one side of the cover is fixed to another end of the support structure;
• at least one magnetic member disposed on the cover;
• a vertical substrate disposed perpendicular to the substrate;
• at least one magnetic sensor disposed on the substrate, wherein the at least one magnetic member is spaced apart from the at least one magnetic sensor, and the at least one magnetic sensor is positioned within an orthogonal projection area of the at least one magnetic member on the substrate;
• and
• a processor electrically connected to the at least one magnetic sensor;
• wherein the cover is operable to move relative to the substrate via the support structure, and the at least one magnetic member is movable with the cover, such that the at least one magnetic sensor senses a magnetic force change and correspondingly generates a sensing signal;
• wherein the processor converts the sensing signal into a control signal, and transmits the control signal to an electronic device;
• wherein the electronic device controls movement of a cursor according to the control signal, or the electronic device uses the control signal for direction control of an application program, or as a mouse single-click signal or a mouse double-click signal;
• wherein the at least one magnetic sensor included in the input device is plural in number;
• wherein at least one of the magnetic sensors is mounted on the vertical substrate and is defined as an auxiliary magnetic sensor;
• wherein the auxiliary magnetic sensor is positioned within an orthogonal projection footprint of the at least one magnetic member on the vertical substrate;
• wherein the magnetic sensors on the substrate is configured to provide X-Y cursor control, and the auxiliary magnetic sensor is configured to provide scroll or accelerated movement control without increasing an overall device height of the input device less than 4 mm enabled by an elastic restoring structure.
