Abstract: A heat dissipation device includes a hollow housing and a speaker. The hollow housing has a first opening and a second opening. The speaker is disposed at the first opening, wherein the speaker includes a diaphragm oscillating within a frequency scope the human ear cannot or hardly hear so as to generate airflow through the second opening.

Abstract: A document snapshot device is provided. The document snapshot device comprises a baseboard, a camera and a foldable supporting means. The baseboard comprises a central area to place a document and a connecting chamfer. The camera comprises a pivot. The foldable supporting means comprises a first supporting means connecting the connecting chamfers, a second supporting means connecting the pivot of the camera and a third supporting means connecting the first and the second supporting means. The first, second and third supporting means can stretch along a first plane to form a first angle between the first and the third supporting means and a second angle between the second and the third supporting means. The camera can rotate along a second plane with the pivot to form a third angle relative to a stretching direction from the second supporting means to the camera to aim at the document to take a snapshot.

Abstract: A multimedia player is disclosed, including a base, a cover rotatably disposed on the base, an engaging mechanism disposed on the base, an elastic element connecting the base and the cover, and a carrier disposed on the cover to carry a media source. When the cover is closed to cover the base, the cover engages the base with the engaging mechanism, and the elastic element is biased to store an elastic potential and when the cover is released from the engaging mechanism, the elastic potential is released to open the cover.

Abstract: A thermal module includes an evaporator, a metal pipe, a main frame, a heat sink, a wick and a cooling liquid. The evaporator is in touch with a heat source and has a gas outlet and a liquid inlet. Two ends of the metal pipe connect separately with the gas outlet and the liquid inlet of the evaporator to from a closed loop. The metal pipe includes a vapor pipe, a condenser and a liquid pipe. The main frame connects with the wall of the metal pipe near the gas outlet. The heat sink is outside the condenser. The wick is positioned in an inner wall of the evaporator and in the gas outlet. The cooling liquid is in the closed loop.

Abstract: An insert-molding mold to combine an inserted piece and a plastic as a product includes a male mold, a female mold, and at least one adjustable support structure. The insert-molding mold may fit different inserted pieces with different thickness. The male mold includes a male mold body, and a male mold core disposed in the male mold body. The inserted piece has an inserted piece thickness. A distance may be generated between the female mold and the male mold core when the male mold matching with the female mold. The distance is larger than the inserted piece thickness. The support structure of the insert-molding mold may support the male mold core and adjust the distance between the female mold and the male mold core to fit the inserted piece thickness.
