Abstract:
An optical recording apparatus includes a traverse, a control circuit board, a shield substrate and an flexible flat cable (FFC). The traverse includes a spindle motor for rotating an optical disc and an optical pickup head for reading and/or writing the optical disc, the optical pickup head moves along a radial direction of the optical disc when reading and/or writing the optical disc. The FFC electrically connects the optical pickup head and the control circuit board and transmits signals between them, and a portion of the FFC adjacent to the second end is bent to facing the shield substrate. The shield substrate includes at least two limiting members, and the at least two limiting members are positioned at two opposite sides of the portion of the FFC facing the shield substrate to enable the portion of the FFC facing the shield substrate to move along the first direction.
Abstract:
A cable positioning mechanism to hold at least one cable in position includes a first sidewall, a second sidewall, and a third sidewall. The second sidewall and the third sidewall are respectively connected to opposite ends of the first sidewall. A first positioning member projects from the top of the first sidewall and extends in a direction substantially perpendicular to the first sidewall. A second positioning member projects from the top of the second sidewall, and a third positioning member projects from the top of the third sidewall. The first positioning member, the second positioning member, and the third positioning member cooperatively restrict the movement of the at least one cable.
Abstract:
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.

Abstract:
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.
Abstract:
An exemplary key device includes a circuit board, a frame, a cap, a partition board and two protrusions. The circuit board has two contacts thereon. The cap is configured on the frame and includes a bottom surface facing the circuit board. The partition board extends down from the bottom surface and abutting against the circuit board. The two protrusions are at two opposite sides of the partition board. The two protrusions extend down from the bottom surface, and each includes a distal end adjacent and above a respective one of the contacts of the circuit board.
Abstract:
A casing of an electronic device includes a holder, a cover and a wire baffle structure. The holder includes a supporting post. The supporting post axially defines a mounting hole therethrough. The cover includes a fixing post corresponding to the supporting post. The fixing post axially defines a fixing hole therethrough. The fixing hole communicates with the mounting hole. The wire baffle structure is formed at a top end of the supporting post. The wire baffle structure encircles a free end of the fixing post.
Abstract:
An exemplary electronic device with a speaker includes a mounting plate, a speaker mounted on the mounting plate, two fasteners mounting the speaker, and a buffer washer squeezed between the mounting plate and the speaker. The buffer washer is capable of absorbing vibration of the speaker. Each of the fasteners includes a head portion and a post portion. The post portion is mounted on the mounting plate and is located outside the speaker. The head portion presses the speaker to abut against the buffer washer.
Abstract:
A printed circuit board assembly (PCBA) includes a printed circuit board (PCB) with through holes, a supporting member standing on the PCB adjacent to the through holes, and an electronic component mounted on the PCB is provided. The electronic component includes a component body and a plurality of conductive leads. Fixing ends of the conductive leads of the electronic component is received in the though hole and electrically and mechanically fixed to the PCB. The component body of the electronic component is supported by the supporting member.
Abstract:
A cable positioning mechanism includes a main body and first and second positioning members arranged on the main body. The first positioning member includes a first surface and a second surface connecting with the first surface. The second positioning member includes a first end parallel to the second surface and a second end parallel to the first surface. The second end cooperates with the second surface to define a first holding space for allowing a cable being placed thereinto. The first end cooperates with the first surface to define a second holding space communicating with the first holding space. The second positioning member further includes a hook. The hook extends into the second holding space and clamps the cable to the main body when the cable is rotated to be received in the second holding space. An electronic device using the cable positioning mechanism is also provided.
