A key sound generation device for a silicone keyboard includes a seat and a press block. The seat or the press block is provided with a torsion spring. The press block is biased by the torsion spring to move up so that the product provides better handfeel. Meanwhile, when the press block is pressed or released, the torsion spring hits the seat or the press block to produce a sound, providing a better auditory effect.

The present invention provides a keyboard device, including an elastic sheet-like member, a keycap configured to hold the elastic sheet-like member, a membrane circuit board disposed below the keycap, a key baseboard disposed below the membrane circuit board, and a positioning frame cover disposed above the elastic sheet-like member. The positioning frame cover and the key baseboard hold the keycap and the membrane circuit board in an up-and-down direction. The keycap is evenly born on the elastic sheet-like member held by the keycap. A shaking and unstable phenomenon does not occur and the elastic sheet-like member can block external foreign matters from falling into the keyboard device.

According to various embodiments, there is provided a key assembly including a housing including a sliding groove on an inner surface of the housing and further including a contact surface above the sliding groove; a plunger at least partially fitted into the housing, the plunger including a protrusion; a sound producing member provided at least partially in the sliding groove, the sound producing member configured to produce sound by impacting the contact surface; wherein the sound producing member includes a connecting portion obliquely extending to an abutting portion, the abutting portion arranged below the protrusion; wherein the plunger is displaceable downwards to deform the connecting portion using the protrusion, the deformed connecting portion being reboundable to cause impact the sound producing member to impact the contact surface.

A push switch includes a casing, an operation body movable into and out of the casing, and a switch element operable with the movement of the operation body into and out of the casing. The casing includes a first outer peripheral wall, a first inner peripheral wall, a first guide provided to the first outer peripheral wall, and a second guide provided to the first inner peripheral wall. The operation body includes a second outer peripheral wall, a second inner peripheral wall, a first engagement portion provided to the second outer peripheral wall and slidably engaged with the first guide, and a second engagement portion provided to the second inner peripheral wall and slidably engaged with the second guide. A clearance between the second guide and the second engagement portion is smaller than a clearance between the first guide and the first engagement portion.

A keyboard switch includes a base, a static contact, a movable contact, an upper cover, a button and a reset spring; the upper cover is buckled to the base; one end of the button is install on the base and the other end passes through the upper cover; the upper and lower ends of the reset spring respectively abut against the button and the base; at least two balance bars for preventing the button from tilting; at least four rotating grooves and guiding grooves for installing the balancing levers are further included; the body of the balance levers are rotatablely rotatably embedded in the rotation grooves, and both ends of the balancing lever are rotatablely rotatably embedded in the corresponding guiding grooves and move back and forth along the guiding grooves.

Provided is a button guide structure that makes it possible to achieve the reduction in cost and man-hour and the improvement in quality. In a button guide structure in which a push button 23 is provided on a front panel 11 through a guide unit in a slidable manner, the push button 23 operating a switch, the front panel 11 configuring a front surface of an electronic apparatus or the like, the front panel 11 includes a tubular portion 11b into which a part of the push button 23 is inserted, the push button 23 includes: a button main body portion 23a that is inserted into the tubular portion 11b; and an outer tubular portion 23b that is provided so as to surround the button main body portion 23a and that encloses the tubular portion 11b when the button main body portion 23a has been inserted into the tubular portion 11b, and the guide unit constituted by a rib 11k and a slit 23k is provided on an outer surface 11w of the tubular portion 11b and the outer tubular portion 23b.

Aspects of the disclosure relate generally to keyboards for computing devices. For example, rather than using a dome, the keycap may include one or more magnets. In one example, a second magnet may be placed adjacent to a switch or magnetic sensor on a circuit board. The magnets may be arranged so that they repel one another in order to force the keycap away from the switch. Webbing between the keycaps may be used to keep the keycaps from falling off of the device. To keep the keycap from moving laterally, the keycap may include two or more flanges held in place by rails. Other arrangements of magnets or magnetic plates may also be used. If a magnetic sensor is used, it may be calibrated to adjust the sensitivity of the keys, for example, how far a user must press the keycap in order to have the pressing register.

A keyboard structure and assembling method thereof are provided. The keyboard structure includes a baseplate, a keycap and a frame having a hook body. The keycap can be inserted into the frame and restricted by the hook body, so that the range of movement of the keycap is restricted. The keycap cannot be separated from the frame so that the coupling of the frame and the baseplate is not interfered by the keycap. Thus, the present invention can effectively simplify the assembling process of the keyboard.

A keyboard device includes a key structure, a base plate and a soft fixing element. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft fixing element. The soft fixing element is disposed on the base plate. The soft fixing element has an accommodation space. The stabilizer bar is inserted into the accommodation space, so that the stabilizer bar is connected with the base plate. After a fixing post of the soft fixing element is penetrated through a fixing hole of the base plate, the fixing post is thermally treated to form the hot melt fixing structure. Consequently, the soft fixing element is firmly fixed on the base plate. Since the metallic stabilizer bar and the metallic base plate are separated by the soft fixing element, the keyboard device is capable of reducing noise.
