摘要:
The present invention relates to a portable terminal, and to a method and apparatus for improving broadcasting reception performance of the portable terminal by filtering a transmission frequency of a radio frequency unit introduced to a broadcasting reception path without experiencing broadcast signal loss. The filtering can be achieved using a filter that includes a variable capacitor in the broadcasting reception path. Accordingly, the transmission frequency of the radio frequency unit may be filtered without a broadcast signal loss. A capacitance of the variable capacitor may be controlled according to the broadcast channel.

An earphone connector of a mobile terminal prevents noise from occurring when inserting and removing an earphone. The earphone connector of a mobile terminal includes a main body having a passage for inserting an earphone. Aground terminal, aright sound terminal, and a left sound terminal are disposed at a preset position of the main body to contact with a corresponding ground terminal, right sound terminal, and left sound terminal of the earphone, respectively, when the earphone is inserted into the passage. A microphone terminal contacts with a corresponding microphone terminal of the earphone when the earphone is fully inserted. And an elastic member applies an external force such that the microphone terminal does not contact with at least one of the corresponding right sound terminal and the left sound terminal of the earphone before the earphone is fully inserted.
