Abstract: A backlit logo device includes an elongated light guiding member and two sources. The two light sources are arranged at opposite ends of the light guiding member. The light guiding member includes a display surface. The display surface includes a transparent logo so light from the light sources passes through the logo. The light guiding member further includes a light reflecting surface opposite to the display surface. The light reflecting surface includes a plurality of light diffusing portions formed in a middle portion of light reflecting surface. The light diffusing portions are configured to diffusely reflect the light from the light sources to the display surface.

Abstract: An adjustable stand, for supporting a device having a lateral surface defining a number of recessed portions, includes a base, a rotating frame, and two connecting axles. The rotating frame includes a chassis and two opposing arms extending arcuately and upward from the chassis, wherein the chassis is rotatably connected to the base. The two connecting axles are rotatably connected to the two opposing arms, respectively. Each of the two connecting axles includes at least one elastic protrusion fitting into one of the plurality of recessed portions, and connecting the device to the two connecting axles, wherein the at least one elastic protrusion is able to deform to allow the device to rotatably connect with the two connecting axles.

Abstract: An electronic device includes a housing. The housing includes a transparent substrate, a transparent texture layer, and a colored texture layer. The transparent texture layer is printed on the inner surface of the transparent substrate and has an uneven surface. The colored texture layer is printed on the uneven surface of the transparent texture layer. A three-dimensional effect printing method is also provided.

Abstract: A vacuum suction base includes a base, a fixing mechanism secured on the base, an adjusting cam, and an adjusting bolt. The base includes a suction piece and a column extending upwardly from the center of the suction piece. The fixing mechanism includes a column housing resisting an edge of the suction piece, and a sleeve connected to the column and defining a through hole. The adjusting cam is rotatably installed in the through hole and partially extends out from the through hole. One end of the adjusting bolt is fixed in the adjusting cam and the other end is engaged in the column.

Abstract: A dual-hook latch formed on a housing of an electronic device includes an arm and two protrusions. The arm protrudes from the housing and defines an opening therein. The two protrusions are formed at opposite sides of the arm. The two protrusions are arranged at an end of the opening. The widths of the two protrusions are smaller than that of the opening.
