Abstract: An apparatus for mounting a speaker module to a portable terminal is provided. The speaker module is mounted to a casing frame of the terminal using a coupling part formed outside a housing of the speaker module, so as not to leave a space between the speaker module and the casing frame in a sound output direction of the speaker module. Therefore, better speaker performance can be achieved by raising the height of the speaker module of the slim portable terminal or increasing the space for the back volume.

Abstract: A Printed Circuit Board (PCB) and an embedded antenna for a mobile communication terminal having double feed points using the same are provided. The embedded antenna includes a PCB having an emission carrier. The emission carrier includes first and second feed points connected to a feed wiring layer of the PCB, as well as an emission pattern to which the feed points are connected. The feed wiring layer supplies a current to one of the feed points, and has a connection wiring for supplying a current from the feed point to the other feed point. Through overlapping between a first resonance spot created by the first feed point, and a second resonance spot, which branches off from the first feed point and connects to the PCB, the frequency bandwidth can be expanded, which accommodates any frequency shift minimizes deterioration resulting from the influence of human bodies, and maintains stable antenna characteristics.

Abstract: The semiconductor laser diode formed with a window at a cleavage facet and a fabricating method thereof are disclosed, wherein a ridge adjacent to a cleavage facet of the semiconductor laser diode and part of the p-clad layer underneath the ridge are etched to form a window, such that a current is not applied to along the cleavage facet to thereby prevent the cleavage facet from being degraded and to enhance reliability of the diode.
