Aspects of the invention include a computer peripheral device comprising an input element that operates based on a performance characteristic, an electropermanent magnet (EPM) assembly including a permanent magnet configured to generate a magnetic field and a magnetizing assembly configured to set an intensity of the magnetic field generated by the permanent magnet, and a magnetorheological (MR) material coupled to the input element. The MR material has a viscosity that changes based on the magnetic field and affects the performance characteristic of the input element.

A keyboard device includes a bottom cover, a supporting plate, a flexible circuit board and plural key structures. The supporting plate is installed on the bottom cover. The supporting plate has a curved arc-shaped profile that is bent upwardly in a direction away from the bottom cover. The supporting plate includes plural perforations. The flexible circuit board is arranged between the bottom cover and the supporting plate. The plural key structures are installed on the supporting plate. The plural key structures are penetrated through the corresponding perforations and contacted with the flexible circuit board.

A keyboard includes: a recessed portion formed along a rear edge and open from a rear surface to a bottom surface; and a magnet located at a recessed portion top surface. A stand includes: a frame body that abuts a rear surface of an electronic apparatus; a plate connected to part of the frame body via a torque hinge, and having a distal edge abutting a placement surface in a state of being open relative to a frame surface of the frame body; a band portion connected to a long-side frame of the frame body along the long-side frame, and having a width that allows side surfaces of the electronic apparatus to be supported; and a bar of an iron material located along a distal edge of the band portion.

User interface apparatuses include a main body having a hinge portion integral with a long-edge at a top edge portion of the main body and a support body having a hinge portion integral with a long-edge at a bottom edge portion of the support body. The hinge portion of the support body is engaged with the hinge portion of the main body for enabling the support body to be pivoted between an in-plane orientation and a deployed orientation relative to the main body. Top and bottom surfaces of the support body each lay one of on and inboard of a reference plane defined by a respective one of a top surface and a bottom surface of the main body when the support body is in the in-plane orientation with respect to the main body. An overall thickness of the main body and the support body is preferably about the same.

An ergonomic keyboard is disclosed. The ergonomic keyboard includes a first key area, a second key area and an adjustment module. The adjustment module is pivotally connected between the first key area and the second key area. The adjustment module includes a first hearing, a second bearing, a rotary knob, an adjustment screw and a supporting base. The first and second bearings are pivotally connected to the first and second key areas respectively such that they allow adjustment of an included angle. The adjusting screw is fixedly connected to the rotary knob and can be rotated together with the rotary knob. The support base is supported on a plane, and an internal thread of the supporting base and the adjusting screw are screwed with each other. Thus, an inclination angle of the first and second key areas can be adjusted by the rotary knob.

The present invention extends adjustable keyboard components. A user can selectively adjust height, tilt, and other keyboard positioning aspects (e.g., pitch, tilt, roll, yaw etc.), to accommodate the specific preferences and/or physical or anatomical characteristics of the user. Keyboard adjustments can tailor a solid foundational position for the user's fingers and hands. The keyboard can include separate left and right modules. Adjustability and separability facilitate highly variable and independent movement of the user's left and right hands. Adjustments and re-adjustments allow a user to make a wide range of alterations to their typing position at any point in time based on circumstances and comfort. As such, adjustments and re-adjustments can (potentially significantly) reduce discomfort and/or injuries associated with repetitive motion.

The invention relates to a combination of a computer keyboard and an extension unit for providing user input to a computing device, e.g. a computer, wherein the keyboard comprises: a housing; buttons and/or keys held by the housing; an electronic module accommodated inside the housing to convert engagement with a button or key into coded form and to transmit the coded form to the computing device as user input,
wherein the extension unit comprises: a housing; a button and/or key held by the housing; an electronic module accommodated inside the housing to convert engagement with a button or key into coded form and to transmit the coded form to the electronic module of the keyboard for further transmittal to the computing device as user input,
and wherein the keyboard and the extension unit are configured to releasably attach the housing of the extension unit to the housing of the keyboard at a plurality of different locations.

The invention discloses a retractable computer keyboard with a hand-painted board and a using method thereof, comprising a support plate, a soft silicone keyboard and a coil spring strip, wherein the kickstand pad is provided with a hand-painted screen with a telescopic a switch, a power indicator is arranged under the telescopic switch, a circuit board is arranged in the kickstand pad, a MCU is arranged on the circuit board, an air pump is arranged on one side of the single chip, and a tee pipe is arranged under the air pump, the aerating tube is arranged under the tee pipe, and the fixing board is provided with a fixing groove with aerifours orifices. The utility model has the advantages such as speeding up of the keyboard unfolding, reducing the space occupation and the overall thickness of the soft silicone keyboard and convenient for storage.

A bracket and an electronic device are provided. The bracket includes a support mechanism and a keyboard. The support mechanism includes a fixed plate and a support seat rotatably connected to the fixed plate. The fixed plate is provided with a fixed surface and a mounting surface. The fixed surface and the mounting surface are respectively located on both sides of the fixed plate which are opposite each other, and the fixed surface can be detachably connected to the electronic equipment. The keyboard is connected to the support seat and is used for inputting data to the electronic device. The electronic equipment such as tablet computer or mobile phone can be detachably set on the fixed surface to support the electronic equipment. Users can input data to the electronic equipment through the operation keyboard without touching the screen of the electronic equipment, which is convenient for users to operate.
