Abstract: A protective cover with ternary structure applied in an electronic product comprises a conjoint plate, a flexible plate connected to the conjoint plate, and a fastening plate connected to the flexible plate. The fastening plate snaps the bottom cover for covering the expansion slot of the electronic product. Also, the conjoint plate, the flexible plate, and the fastening plate are integrated as a whole by double injection technique, and the flexibility of the flexible plate controls the protective cover being closed or opened.

Abstract: A power switch apparatus is disclosed wherein the switch apparatus is applicable in an electronic product comprising a switch device capable of being switched between ON and OFF conditions. The power switch apparatus comprises an active element and a flexible arm. The active element installed inside the electronic product comprises a first connector and is coupled to the switch device. The ON and OFF conditions of the switch device correspond to the different positions of the active element. The flexible arm comprises a second connector and a contactor. The second connector is used to clip with the first connector at the ON condition. The electronic product is configured such that the contactor is not covered and remains accessible. The movement of the contactor is able to transform the shape of the flexible arm and to release the clipping relation between the first connector and the second connector.

Abstract: A wireless communication apparatus integrates a flat speaker (33) onto a liquid crystal display (12) or a rotational shield (3) of the apparatus. The flat speaker includes a vibrator (30) and a transparent vibrating membrane (31) which generates sound when the vibrator vibrates. The transparent vibrating membrane is mounted with a predetermined spacing over the liquid crystal display or over an inner surface of the rotational shield so as to gain a broader voicing surface. Thereby, by providing the flat speaker, the wireless communication apparatus can have a better audio effect.

Abstract: A push button apparatus includes a micro switch, an interface structure located on the micro switch, a push button top cap and a compression spring located between the interface structure and the push button top cap. The push button top cap has a bottom surface which has a protrusive hub located thereunder for housing a top section of the interface structure. The top section of the interface structure is hollow and includes at least one pair of independent and opposing elastic upper arms extending therefrom. Each upper arm has an outer surface that has a retaining jut formed thereon. The protrusive hub has a receiving opening of a selected height formed at a respective location corresponding to the retaining jut to form a restrictive sliding relationship in between and thereby allows the push button top cap sliding in the top section of the interface structure.
