PURPOSE: A mobile terminal is provided to output synthesized sensing information through a single line by synthesizing the sense information about the connected state and the wearing condition of an earphone into one. CONSTITUTION: A first sensor part senses the wearing condition of an earphone. A second sensor part senses whether the earphone is connected to. A synthesizing part outputs the synthesized sensing information by synthesizing the first and the second sensing information into one. The first sensor part outputs a digital signal by sensing the attachment/detachment state of an earphone through all kinds of the sensors. The second sensor part outputs the connection state between a mobile terminal and an ear-jack to a digital signal. The synthesizing part converts the synthesized signal of the digital signals of the first and the second sensor into analog data. |
