A keyboard device is disclosed. The keyboard device includes a base, a key top, a film actuator, a position sensor, and a controller. The key top is movably arranged on the upper surface side of the base. Disposed between the base and the key top, the film actuator bends according to an applied voltage. Also disposed between the base and the key top, the position sensor detects a position of the key top. The controller applies a voltage to the film actuator in order to generate a repulsive force corresponding to the position of the key top detected by the position sensor.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

A keyswitch uses a combination of springs connected in serial for providing a return force to a keycap of the keyswitch. When the keycap moves toward a base of the keyswitch beyond a transition position, one of the springs stops continuously deforming. It leads to an increment of the elastic coefficient of the combination of springs and an increment of the elastic stored energy by the combination of springs. Therefore, during a pressing on the keycap, the keycap can provide a light force feedback and then a heavy force feedback to a user. Further, the keyswitch can use a switch with a lateral motion, which can reduce influence of a resilient force produced by the switch on the up and down movement of the keycap. The keyswitch also can use an elastic piece disposed beside the keycap, which can provide a tactile feedback to the user.

Keyboards, input devices, and related systems include key mechanisms with keycaps and actuators that provide adjustable feedback in response to user input. The actuators are controllable to provide variable tactile force or audible feedback that is dependent upon the user input. Encoders are able to transduce a location or relative position of a keycap as it is being pressed over time, and a signal is provided to actuators to cause them to provide feedback corresponding to the position of the keycap as it moves. The feedback can change the feel or sound of the keycap based on the keycap positions, time of operation, velocity, user identity, and other factors. Thus, the feel or sound of a keyboard or related input device can be adjusted electronically for efficient testing and increased user customization and feedback modes.

A magnetic press key includes a housing and a central shaft body disposed in the housing, wherein the bottom of the central shaft body is extended into the housing, and the central shaft body can reciprocate in the vertical direction in a base after the key cap seat is pressed, a first magnetic element is provided on the upper section of the central shaft body, a second magnetic element which can move up and down is provided under the coaxiality of the first magnetic element, and a third magnetic element is provided in the housing. The first magnetic element and the second magnetic element generate repulsive or attractive magnetic force, and the magnitude of the repulsive or attractive magnetic force can be adjusted by changing the magnitude of the energizing current of the energized coil, so that the use hand feeling of the key cap seat is improved.

A mouse includes a main housing, a key structure, and a pressing force adjusting component. The key structure has a connecting end, a free end, and an elastic section. The connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end. The pressing force adjusting component is movably disposed on the main housing and has a limiting portion, and the limiting portion limits elastic deformation of the elastic section. A location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section.

A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

A dynamic keyboard able to change and adapt the functionality of the keyboard depending on the scenario in which it is being implemented. Each key can have one or more modes assigned to it that is able to change depending on the use. Groups of keys can have more than one mode assigned to it. Different groups of keys can have different modes assigned to them.

A variable force key, comprising a housing, a central shaft, and a magnetic ring, the central shaft extends into the housing, the top end of the center shaft is fixedly provided with a key cap seat, the central shaft can reciprocate in the housing in the vertical direction, the bottom end of the central shaft is fixedly provided with a limit member, the outer wall or inner wall of the bottom end of the limit member is provided with a flange, the magnetic ring sleeves the outer wall of the limit member or is arranged inside the limit member and located at the upper end of the flange. The variable force key further comprises an electromagnet or a hollow coil, which is arranged at the bottom in the housing, and when the central shaft moves downward, the electromagnet or the hollow coil can penetrate inside the limit member.
