Abstract: A speaker system for a mobile device includes first and second audio processing units and first and second speakers for reproducing audio signals and outputting the reproduced audio signals. The speaker system also includes a controller configured for transferring the audio signal to the second speaker if a battery is connected to the mobile device. The first speaker is embedded in a main body of the mobile device and the second speaker is embedded in the battery of the mobile device.

Abstract: The present invention relates to installation of a speaker in a notebook computer. A notebook computer of the present invention comprises a main body including a plurality of input keys; and a display unit installed to be folded with respect to the main body. Further, a speaker is installed below the input keys of the main body. For example, the speaker is installed on a bottom surface of a keyboard plate installed below the input keys. Some of the input keys where the speaker is installed are formed with a sound-passing portion including a plurality of holes.

Abstract: The present invention relates to a hinge frame for a portable computer and a structure for mounting the same. The hinge frame of the present invention comprises a frame body through which a plurality of fastening holes are perforated, a hinge fastening portion which is formed at a portion of the hinge body and to which a hinge unit is fastened, and a plurality of covering portions which are formed along an edge of the frame body and cause parts mounted on a board to be seated therein. The present invention provides the advantages of the hinge unit being more firmly fixed to the main body, improved installation strength of connectors and the like mounted on the main board, and relatively reinforcement of the main board.

Abstract: The present invention relates to a flexible printed circuit board assembly. A flexible printed circuit board assembly of the present invention comprises a flexible printed circuit board having a plurality of circuit patterns; a connector mounted at a location spaced apart by a certain distance from an end of the flexible printed circuit board and electrically connected to the, circuit patterns; and a stiffener attached to a region on a bottom surface of the flexible printed circuit board below the connector and having a size corresponding to that of the connector. A connector inside portion and a connector outside portion of the flexible printed circuit board located inside and outside with respect to the connector can be bent. The connector outside portion is bent and bonded to a bottom surface of the stiffener, and the connector inside portion is bent and bonded to a bottom surface of the connector outside portion.
