The composite heat dissipation material comprises at least one artificial graphite layer and a graphitic heat dissipation layer. The graphitic heat dissipation layer includes a graphite material layer, and the graphite material layer is not formed from artificial graphite materials. Further, the graphitic heat dissipation layer is bonded to the artificial graphite layer. The composite heat dissipation material of the present application can efficiently and rapidly dissipate heat energy produced from a heating source, thereby lowering temperature thereof.

Composite heat dissipation material

The present invention relates to a heat-dissipating device for an electronic device, comprising a graphite planar body, one or more metal layers, an insulation film and an adhesive. The heat-dissipating device is optionally attached to a heat sink. The method of using the heat-dissipating device to dissipate heat is also disclosed.

Use of a graphite heat-dissipation device including a plating metal layer

An apparatus for a case for an electronic device containing one or more antennas is disclosed. The apparatus for the electronic device comprises a metal layer, a dielectric layer and a masking layer, wherein the masking layer has one or more channels, and some of the channels have antenna therein. The antenna extends from one wall to another wall of the case.

Apparatus for a case for an electronic device

A voice coil motor device for positioning is disclosed. The voice coil motor device for positioning includes a fixed element, a moving element and a connector. The moving element is movably disposed on the fixed element. One end of the connector is connected with the fixed element and the other end of the connector is connected with the moving element. A piezoelectric element is disposed on the connector or deposed between the moving element and the fixed element. The piezoelectric element can be deformed with the movement of the moving element to generate a displacement signal of a moving element. The positioning of the voice coil motor can be achieved precisely basing on the judgment on the displacement signal of the moving element generated with the movement of the moving element by the piezoelectric element.
