An exemplary electronic device includes a main housing and a cover pivotably attached to the main housing. The main housing has a printed circuit board received therein. A Hall sensor is fixed and electrically connected to the printed circuit board. The cover has a display and a speaker located adjacent to the display. The speaker includes a magnet. The Hall sensor can detect variation of a magnetic field of the magnet to output different voltages, thereby actuating the display to turn on or turn off.

A casing includes a base plate and a supporting post extending upwardly from the base plate. The base plate and the supporting post are integrally formed as a single monolithic piece from the same material. The supporting post axially defines a fixing hole therein. The fixing hole has an opening at a top free end of the supporting post. The fixing hole includes a first section adjacent to the opening, a second section far from the opening and spaced from the first section, and a chamfer section between the first section and the second section. The first section has a diameter larger than that of the second section.

An electronic device includes a first housing, a second housing, a component member, a screw, and a gathering post. The first housing defines a through hole. The second housing combines with the first housing to form a receiving space. The component member is received in the receiving space. The screw passes through the through hole of the first housing to screw in a predetermined position of the component member. The gathering post gathers filings falling from the component member when the screw is screwed in the component member.

An electronic device includes at least an electric wire, a first cover, and a second cover. The electric wire is mounted between the first cover and the second cover. The first cover includes a wire retainer integrally forming a restraining portion to fix the electric wire on the first cover. The second cover includes a hook securely engaged with the wire retainer of the first cover to fix the second cover on the first cover.

An exemplary electronic device includes a cover, a circuit board and a driving module both mounted on the bottom cover, an electronic component fixed on the circuit board, and a top cover covering the bottom cover. The driving module has a rotating shaft adapted for supportively driving an optical disk to rotate. The electronic component generates heat during operation. Through holes are defined in the top cover and located at a periphery of the rotating shaft. When the optical disk is mounted on the rotating shaft and driven to rotate by the rotating shaft, air heated by the electronic component in the electronic device can flow out of the top cover via the through holes, and rotation of the optical disk facilitates such airflow.

An optical disk player includes a main body, a hinge, and a display. The main body includes a cover and an opposite base. The hinge includes a fixing portion coupled with the cover of the main body. The display is pivotably connecting to the main body by the hinge. The fixing portion defines a locating hole thereon. The cover defines a holding portion and a first locking portion. The first locking portion comprises a pole and a hook at an end of the pole. The holding portion of the cover is engaged in the corresponding locating hole of the fixing portion. The hook and the pole of the first locking portion are clasped different sides of the fixing portion.

An optical disk player includes a main body, a cover engaging with the main body, a pivot module, and a deceleration module. The pivot module includes a torsion spring, two ends of the torsion spring being fixed on the main body and the cover respectively. The deceleration module includes a first deceleration portion arranged on the main body and a second deceleration portion arranged on the pivot module. The first deceleration portion contacts the second deceleration portion and frictional forces therebetween reduces the speed of opening the cover.

A display device includes a shell, a display panel disposed within the shell and at least one securing member fixing the display panel to the shell. The display panel is covered with a front cover and a rear cover opposite to the front cover. The at least one securing member is fixed to the shell and resists at least the rear cover of the display panel. The at least one securing member includes a conducting member. The conducting member resists at least the front cover of the display panel to conduct static electricity therefrom.

An electronic device includes an EMI shielding board, two electronic components and a flat cable. The EMI shielding board includes a first side and a second side opposite to the first side. The two electronic components are arranged at the first side of the EMI shielding board. The flat cable is connected between the two electronic components. The EMI shielding board further includes a first through slot and a second through slot both configured therein. The flat cable passes through the EMI shielding board via the first and second through slots. A part of the flat cable is on the first side of the EMI shielding board, and the remaining part of the flat cable is on the second side of the EMI shielding board.
