A multifunctional earphone in a mobile terminal is provided to improve the convenience of a user by installing an antenna at the earphone of a mobile terminal in order to receive the broadcasting signal of a preset frequency band. A multifunctional earphone(200) in a mobile terminal(300) is comprised of an antenna(100), an impedance matching unit(210), the first amplification unit(220), the second amplification unit(230), and a speaker(240). The antenna(100) receives broadcasting signals of a specific frequency band. The impedance matching unit(210) matches the impedance of the antenna(100). The first amplification unit(220) amplifies received broadcasting signals and transmits the amplified broadcasting signals to the mobile terminal(300). The second amplification unit(230) amplifies the audio signals outputted from the mobile terminal(300). The speaker(240) outputs the amplified audio signals.
