An earphone antenna includes: earphone cords; an earphone portion; a coaxial cable; and a pin plug connector portion; wherein the earphone cords cooperate with a shielded line of the coaxial cable using a connection point with the coaxial cable as a feeding point to constitute an antenna for receiving RF signals; wherein conductor lines constituting a core wire of the coaxial cable form signal lines for transmitting audio signals and a ground line; and wherein the coaxial cable is connected with a separation-superimposition circuit portion which is mounted at a side of the pin plug connector portion or at a side of a wireless electronic device and acts to separate the RF signals and the audio signals and to superimpose the audio signals. |
