Abstract: A portable electric device, to provide mobile phones and PDA functions, includes a main body and a sub-body. The main body has a first keyboard and a second keyboard that are operated in different directions. The sub-body has a large display screen on one side and a small display screen on the other side. The sub-body is pivotally coupled on one side of the main body, corresponding to a QWERTY keyboard through a biaxial hinge. The sub-body may be selectively having a large display screen or a small display screen, folding over the main body, to cover the QWERTY keyboard, or to be lifted, to form an angle with the main body, to provide different operation modes for the mobile phone or PDA functions.

Abstract: A loudspeaker apparatus includes a speaker unit and a front cover. The speaker unit generates acoustic waves according to an external electronic signal. The front cover located in front of the speaker unit includes a plurality of elastic spacers and a diaphragm, and the elastic spacers and the diaphragm form an enhanced chamber, such, that the acoustic waves generated by the speaker unit go through the enhance chamber, and then drives the diaphragm to generate the acoustic waves again.

Abstract: A portable electronic product with a Qwerty keyboard has a single display for reducing the manufacturing cost and a Qwerty keyboard for inputting data more conveniently. The portable electronic product includes a housing, a Qwerty keyboard mounted in the housing and a display. The Qwerty keyboard is exposed to a bottom surface of the housing and has an outer surface that is lower than the bottom surface of the housing. The display is assembled on a top surface of the housing and has a side edge that is partially or fully mounted with one edge of the housing pivotally. Therefore, the display is able to swivel relative to the housing. When the user needs to input data, the display can be turned to a position that simultaneously faces to the user with the Qwerty keyboard.

Abstract: A handheld electronic data processing device includes a first body, a second body and a hinge seat. The first body has a first keypad and a second keypad located in different directions. The second body has a display screen. The first body and the hinge seat are coupled through a first hinge such that the hinge seat is rotatable relative to the first body about a first rotational axis. The second body and the hinge seat are coupled through a second hinge such that the second body is rotatable about two rotational axes relative to the hinge seat. Thereby the second body may be swiveled relative to the first body about three rotational axes to provide varying operation modes corresponding to different functions.

Abstract: A portable electronic device includes a housing and a pressure sensor installed on the housing for sensing pressure applied to the portable electronic device. The portable electronic device further includes a logic unit for controlling operation of the portable electronic device according to a sensing result of the pressure sensor.

Abstract: A rotation shaft mechanism is proposed, whereby a display portion of a portable computer is upheld when the display portion is lifted, so that turning of the display portion will not rub against the surface of base portion of the portable computer. The rotation shaft mechanism includes a vertical shaft and two horizontal shafts each has an eccentric protuberance. The vertical shaft includes a first component having a pair of symmetric projective ears and a cylinder body, a second component slipped onto the cylinder body, and a third component also slipped onto the cylinder body. The horizontal shafts pass through and join the projective ears. The second component has projective walls corresponding to the eccentric protuberances. The first and second components interfere each other to rotate synchronously. An elastic component is disposed between the lower portion of the cylinder body and the bottom face of the third component.
