A keyboard stabilizer is adapted to reduce the clanking and rattling sounds that it makes during operation. The invention takes advantage of the surprising result that adhesive, in proper amounts, can act as a sound dampener. First, a circumferential score is cut near each tip of the wire. Second, adhesive is applied to several critical points on the housings, stems, and wire. Third, lubricant is applied to several critical points on the housings, stems, and wire. The stabilizer is then assembled from the prepared parts.

Electrical equipment such as a tablet computer cover, a laptop computer, or other equipment may include keys. Each key may have a key member. Coatings such as opaque coating layers may be formed on the key members. Opaque coating layers may be patterned to form symbol-shaped openings associated with key labels. Opaque coating layers may also have recessed peripheral portions and other features to enhance the appearance of the keys. Metal coating layers such as physical vapor deposition metal layers may be incorporated into the keys. Key members may have outer surfaces and opposing inner surface on which patterned coating layers may be formed. Peripheral edge portions of the key members may extend between the outer and inner surfaces and may be coated with metal coating layers to form reflective metal trim structures. Backlight illumination for the keys may be formed form light sources such as light-emitting diodes.

A mobile terminal having a terminal main body including a front case forming an internal area including a submergence area into which water is introduced and a waterproof area into which water is blocked from being introduced, and an internal frame; a first unit including a key module mounted in the terminal main body, and generating a control command when a pressing occurs, the key module being positioned in the submergence area and moving due to an external force; a second unit positioned in the waterproof area, and when the pressing occurs, generates a signal; an elastic deformation layer of which a portion is elastically deformed due to movement of the first unit, so the second unit is pressed by the first unit; and a waterproof layer attaching the elastic deformation layer and the front case so partitioning results in the submergence area and the waterproof area.

A keyboard device includes a keyboard base, a flexible protection cover and a protective frame. The flexible protection cover is located over the keyboard base to cover the key structures that are disposed on the keyboard base. The protective frame is disposed on the flexible protection cover. Moreover, plural hollow protrusion structures of the flexible protection cover are partially penetrated through corresponding openings of the protective frame and exposed outside the protective frame. The elastic buffering parts of the flexible protection cover are disposed within corresponding concave structures of the protective frame and covered by the protective frame.

The present invention provides a mobile terminal comprising: a terminal main body comprising a front case and an internal frame forming an internal area including an inundation area in which terminal water flows in and a waterproof area in which the inflow of water is blocked; and a key module mounted on the terminal main body and forming, by pressing, a control command, wherein the key module comprises: a first unit disposed in the inundation area and moved by an external force; a second unit disposed in the waterproof area and a signal generated by pressing; an elastic deformation layer having one region elastically deformed by movement of the first unit such that the second unit is pressed by the first unit; and a through hole, which allows the elastic deformation layer and the front case to be attached so as to partition the inundation area and the waterproof area and through which the first unit penetrates.

A soft-rubber keyboard having hard sheets with convex switches includes: a printed circuit film, a keyboard base plate for supporting the printed circuit film, an integrated soft-rubber keycap and a plurality of hard sheets. The integrated soft-rubber keycap includes a plurality of key units. The key unit is formed by connecting a soft-rubber key surface, a soft-rubber supporting body and a soft-rubber key base. Each key unit corresponds to one hard sheet. A convex switch body is downwardly integrated with the center of the hard sheet. The hard sheet is bonded to via an adhesive or integrally formed by injection molding with the bottom surface of the soft-rubber key surface. The convex switch body in the center of the hard sheet corresponds to a circuit switching point of the printed circuit film. The soft-rubber keyboard has the characteristics of simple processing, low cost, simple assembling and good press stability.
