  • Patent number: 10321233
    Abstract: A method and a portable electronic apparatus for adaptively adjusting a playback effect of speakers are provided. The portable electronic apparatus includes a speaker enclosure volume adjusting device and a processor coupled to the speakers and the speaker enclosure volume adjusting device. In the method, the processor detects a usage demand for the portable electronic apparatus and accordingly determines an audio mode. Based on the determined audio mode, the processor selects and activates multiple speakers, and adjusts an enclosure volume of at least one of the activated speakers, so as to change an audio frequency range of the at least one speaker and an overall audio frequency range covered by the activated speakers. Finally, the processor plays an audio through the activated speakers.

  • Patent number: 7635199
    Abstract: The present invention is related to an illumination device capable of producing ambient light and whose structure can be efficiently manufactured and assembled. The illumination device comprises: a substrate electrically connect to a power supply, a plurality of light sources attached to a surface of the substrate, a reflection body with a reflection surface situated a distance from said plurality of light sources, a shell having a diffusion surface situated a distance from said reflection surface. The illumination device may further comprise a housing for receiving and supporting the substrate and the reflection body. The housing is configured to join with the shell and can be further attached to an external device receiving the ambient light. The light emitted from the light sources is reflected by the reflection body to the diffusion member and then radiates outwardly to the surrounding environment of the shell. The reflection surface of the reflection body is inclined at angle relative to the substrate.

  • Patent number: 6941565
    Abstract: A disk carrier mechanism is used for moving a disk between an insertion position and a reading position. The disk carrier mechanism includes a wedged member set, a fixing board, a sliding board, and a driver set. The wedged member set includes multiple wedged members, each with a wedged part for wedging a disk. The driver set is formed on the fixing board for driving the sliding board to move relative to the fixing board. After being inserted, a disk is wedged in the wedged part and the force of inserting the disk pushes the sliding board to move to the position where the sliding board makes contact with the driver set. Thus the driver set drives the sliding board to place the disk in the reading position. Thus fewer members are used to accomplish the goal of moving the disk, which simplifies the actions of members, the fabrication of the mechanism, and reduces cost.

  • Publication number: 20050011709
    Abstract: A dynamic vibration reduction system, applicable in an electronic product, includes a main buffering unit, an auxiliary buffering unit, and a driving module. The main buffering unit is connected to a carrier of the electronic product to reduce vibrations of the carrier. The auxiliary buffering unit is movably mounted on one side of the carrier. The driving module is assembled in the auxiliary buffering unit to either abut the auxiliary buffering unit against the carrier and reduce the vibration of the carrier, or space the auxiliary buffering unit away from the carrier at a predetermined distance. The vibration reduction of a system is variable with the control of the connection between the auxiliary buffering unit and the carrier to maximize the performance of the electronic product.

  • Patent number: 6817020
    Abstract: An ejection structure for an optical disk drive having a tray. The ejection structure is disposed on the back surface of the tray to eject the tray. The ejection structure comprises a base, a motor, a worm gear, a limit switch, a main gear, a first pushing arm, a second protruding pin, a twisting spring, a third protruding pin and a second pushing arm. When the motor drives the worm gear, the worm gear drives the main gear to rotate, so that the first pushing arm and the second pushing arm rotate and move relatively to eject the tray. When the first pushing arm is pushed from the outside of the tray, the first pushing arm drives the second pushing arm to move linearly to eject the tray.

  • Patent number: 6728190
    Abstract: A disc receiver device comprises a loader that can rotate through a motor and transmits power. The loader comprises a plurality of gears meshing with each other and includes a sun gear and a planet gear. The planet gear has two degrees freedom of motion of a self-rotation and a revolution that takes the sun gear as a center. The tray is driven to move by means of the self-rotation of the planet gear, enabling the tray has a retracting position projecting out of the disc driver and a loading position moving into the disc driver. And a set of sliding plates that are engaged with shafts of a mecha are driven to move by means of the revolution of the planet gear, enabling the sliding plate has a first position corresponding to the retracting position and a second position corresponding to reading position to control the inward and outward movement of the disc and the upward and downward movement of the mecha.

  • Patent number: 6717331
    Abstract: This specification discloses a piezoelectric ultrasonic motor with multi-layer thin disks. A buzzer disk made of a piezoelectric material is supplied with an alternate voltage to produce alternately expanding and shrinking deformation. An elastic vibration disk in connection with the buzzer disk produces standing waves to transport kinetic energy to the exterior. A driving module symmetric in the vertical or horizontal direction is also formed. This does not only reduce the abrasion among the components, but also provide homogeneous forward and reverse driving forces.
