An earphone device having an integrated antenna, comprising a coaxial cable, a receiver and a signal processing module. The coaxial cable includes a first end and a second end. The receiver includes an antenna module and a speaker module, where the antenna module and the speaker module are in connection and are electrically connected to the first end of the coaxial cable. The signal processing module includes a baseband unit and a radio frequency unit, where the baseband unit and the radio frequency unit are in connection and are electrically connected to the second end of the coaxial cable. Thus, the earphone device having an integrated antenna of the instant disclosure can reduce the surface area of the main board effectively to enhance the efficiency of the antenna.
