Abstract: A mobile phone includes a main display; a subsidiary display; and a main body mounted between the main display and the subsidiary display. The subsidiary display is retractable along a first direction relative to the main display, and the main body is retractable along a second direction perpendicular to the first direction.

Abstract: An upper case of the display section includes a first connecting portion having a cylindrical hole, into which an inner cylinder of a dummy hinge composed of two cylindrical portions having the same axis and different diameters is inserted rotatably, wherein the first connecting portion protrudes from an end of the upper case. An upper case of the keybutton section includes a second connecting portion located, along a hinge axis, on the center side of the first connecting portion, and having a cylindrical hole into which an outer cylindrical portion of the dummy hinge is inserted unrotatably, wherein the second connecting portion protrudes from an end of the upper case. The hinge structure comprises a stopper for fixing the dummy hinge, which can be inserted as the dummy hinge is buried in the cylindrical hole, with the inner cylindrical portion inserted into the cylindrical hole of the first connecting portion.

Abstract: One embodiment of the present disclosure relates to a radio frequency (RF) device for communicating on a wireless network. The device includes an antenna coupled to an RF circuit. The device further includes a body housing the RF circuit and the antenna. The device yet further includes a support member extending from the body. The support member is configured to be coupled to an object. The support member is prevented from moving laterally and vertically relative to the object when coupled to the object. The support member and body are configured to allow the body and the antenna to rotate about an axis when the support member is prevented from moving laterally and vertically relative to the object.

Abstract: A wireless communication device includes a wireless communication device housing member, and a modular keypad removably attachable to the wireless communication device housing member without use of a separate tool.

Abstract: The present invention is to provide a mobile phone comprising a body and a housing. A hollow is formed within the housing and the body is slidably disposed in the hollow. The hollow has an opening in an end of the housing and the other end terminated at a closed end of the housing distal the opening. A display (e.g., LCD (liquid crystal display)) is disposed on a front surface of the housing. The body comprises a circuit board and an input device. The circuit board is installed within the body and comprises electronic circuits and devices for controlling the components of the mobile phone. The input device (e.g., alphanumeric keypad) is disposed on a front surface of the body for operating the mobile phone. The body is capable of being engaged with the housing and being slid towards outside of the hollow through the opening to expose the input device for a user to make a phone call.

Abstract: An automatic sliding-type mobile communication terminal comprising a motor, a pair of engaging members, which are selectively engageable with each other, and position detecting means so that a first terminal body and a second terminal body are smoothly slid relative to each other in an automatic/semi-automatic mode or an automatic/manual mode, a method of automatically driving an automatic sliding-type mobile communication terminal, and a method of detecting an incoming call to an automatic sliding-type mobile communication terminal.

Abstract: A mobile terminal includes a speaker arrangement for providing surround sound. The terminal includes a folder hinged at a main body and having an LCD attached thereto, speakers mounted at the folder and implementing a three-dimensional surround-sound effect, and a sliding unit for sliding at least one of the speakers when the speakers produce the three-dimensional surround-sound effect. Because the distance between the speakers can be widened according to a user's selection, three-dimensional surround-sound can be maximized and thus product quality can be significantly enhanced.

Abstract: An object of the invention is to smoothen the loading of a battery pack, to ensure the electric connection between the battery pack and the main body of a mobile electronic apparatus, and to reduce the manufacture cost.

Abstract: A remote (or wire) control auxiliary push button dialing system includes a push button device, and a mobile telephone auxiliary dialing device. The mobile telephone auxiliary dialing device together with a mobile telephone is mounted in a receptacle. The push button device includes a keyboard push button and a key signal processor. The mobile telephone auxiliary dialing device includes a signal receiving controller, a pair of X/Y axis sliding arms, and a press module. In such a manner, the signal receiving controller receives push button coding signals transmitted by the push button device to serially control the pair of X/Y axis sliding arms to move longitudinally and transversely to fixed coordinate positions so as to further perform auxiliary push button dialing action of the mobile telephone by the press module.

Abstract: A fixation arrangement for detachably mounting a battery pack onto a cellular phone includes two parallel guide rails defined on the cellular phone, a sloping depression defined between the guide rails and sloping outward to the guide rails, a recess defined adjacent to the sloping depression and in a position opposite to the sloping direction of the depression, and a coupling plate integrally formed with the battery pack and having two parallel lips corresponding to the guide rails for slidably engaging onto the cellular phone, a U-shaped slot provided in a position corresponding to the recess and the slot and defining a tongue portion with a tip over the slot when the battery pack is engaged with the cellular phone, a tab protruding from the tip of the tongue portion for inserting into the slot when the battery pack is engaged with the cellular phone, and two cutouts respectively extending between one of the lips and the U-shaped slot and in a direction substantially parallel to the guide rails.

Abstract: The cellular phone of the present invention includes a display device provided on the front surface of a main body, and a cover movable relative to and preferably, rotatably mounted on, the main body and having keypads provided on the front and rear surfaces thereof, respectively. A plurality of number keys for a mobile communication are preferably arranged on the keypad provided on the front surface of the cover, and a plurality of character keys for the Internet are preferably arranged on the keypad provided on the rear surface of the cover. Also, another keypad wherein keys for the mobile communication and the Internet are arranged may be provided on the main body. The cover may be in the form of a flip or folder. The cover may have an area smaller than the main body or a window so that a portion of the display device is exposed even when the cover is closed.
