Abstract: A slidable and automatic rotatable apparatus disposed in a portable electronic device and providing the portable electronic device, which includes a first housing and a second housing, with a first status and a second status is provided. The apparatus includes a third housing, a protruding part disposed on the second housing and opposite to the first track, and a rotary module passing through the second track. The third housing, which is fixed on the first housing and movably connected with the second housing, includes a first track, a second track, and a first rib disposed on a first side of the second track. A first end of the rotary module is fixed on the second housing, while a second end is disposed between the first housing and the third housing. The rotary module has at least one protruding point positioned at the second end for contacting the first rib.

Abstract: A mobile phone has a circuit board and a connector capable of assembling both a microphone and a coin battery. The connector includes an insulative body having a first engaging sink for positioning the microphone and a second engaging sink for positioning the coin battery. The connector has a first, second, and third conductive terminals for connecting the microphone and the circuit board, and a fourth and fifth conductive terminals for connecting the coin battery and the circuit board.

Abstract: The present invention provides an antenna engaging mechanism in a wireless communication device, which has a circuit board. The antenna engaging mechanism comprises a housing that has a nut, an antenna, and an elastic metal piece. The antenna comprises an antenna metal tube and an antenna shell covering one end of the antenna metal tube, wherein the other end has an engaging protrusion column with a taper head and a taper bottom. The elastic metal piece comprises a fixing portion for fixing the elastic metal piece and an elastic arm for holding the engaging protrusion column. While the engaging protrusion column is rotated into the nut of the housing, the taper head holds open the elastic arm. After the taper head passes, the elastic arm springs back due to the elasticity and enables the engagement of the elastic metal piece and the engaging protrusion column at the taper bottom.

Abstract: A hinge mechanism for pivotally connecting a flip onto a housing includes a bush, a spring, and a camshaft. The bush is connected to the flip and has a sidewall, a receiving space defined by the sidewall, and a protrusion. The protrusion is protruded from the sidewall. The camshaft has a first end, a second end, and a shaped notch. The shaped notch includes a first concave portion and a second concave portion, and the protrusion is slidably received within the shaped notch. The first end of the camshaft is slidably coupled to the bush, and the second end of the camshaft is restrictedly coupled to the housing. When the flip is pivoted on the housing, the bush simultaneously rotates around the pivoting axis of the hinge mechanism so that the protrusion slides within the shaped notch from the first concave portion to the second concave portion.

Abstract: A hinge mechanism for pivotally connecting a flip onto a housing includes a bush, a compression spring, and a release button. The bush has a sidewall, a receiving space defined by the sidewall, and a protrusion. The protrusion is protruded from the sidewall. The release button has a shaped notch, which includes a concave portion, a stop portion, and a convex portion formed between the concave portion and the stop portion. The stop portion extends substantially parallel to the pivoting axis. The protrusion is slidably received within the shaped notch. The compression spring is disposed within the receiving space and pressed by the release button and the bush. When closing the flip, the bush rotates synchronously with the flip and the protrusion moves in the shaped notch. When pushing the release button, the flip opens automatically.

Abstract: The present invention relates to a protection structure for use with an electronic device having an interchangeable housing. The protection structure includes a first protection element and a second protection element. The first protection element is disposed between an upper cover and an electronic module of the electronic device. The second device is disposed between a lower cover and the electronic module of the electronic device and coupled to the first protection element. When a user disassembles the upper and lower covers, the first and second protection elements protect the electronic module.

Abstract: A mobile phone with a dual PCB structure. The mobile phone includes a first PCB with electronic elements disposed thereon. A conductive enclosure is disposed on the first printed circuit board. A second printed circuit board has a plurality of layers and contacts the conductive enclosure. The first printed circuit board, the conductive enclosure and the second printed circuit board form a closed space within which the electronic elements are disposed. The first layer next to the conductive enclosure is an exposed copper layer grounded to protect the electronic elements from EMI.
