Abstract: A speaker device installed in an earpiece, for improving an antenna property in a wireless portable terminal is provided. The speaker device includes a housing, a magnet is installed on the housing, a diaphragm located a predetermined distance away over the magnet and includes a coil situated at a position corresponding to the magnet, and a cover covers the diaphragm and is in engagement with the housing, thereby forming a module. At least one inductor is provided at a feeding portion of the coil formed or installed on the diaphragm, thereby preventing the speaker device from resonating at a radio frequency (RF).

Abstract: A built-in antenna apparatus and a portable terminal including the same are provided. The apparatus includes a substrate, an antenna carrier, a plate type antenna radiator operating in at least one resonance band, and at least one sub antenna radiator. The substrate has a feeding pad for electrically coupling with a Radio Frequency (RF) connector. The antenna carrier for establishing preset distance from the substrate. The plate type antenna radiator is disposed on the antenna carrier. The sub antenna radiator is electrically coupled with the plate type antenna radiator.
