The present invention discloses an audio extension system. The audio extension system comprises a permanent magnet; a holder having a concave portion for holding the permanent magnet; a tube disposed at a gap between a side of the permanent and a side of the concave portion of the holder for holding a coil surrounded a periphery of the permanent magnet and supported the coil to vibrate freely; and a conducting part, mounted at one end of the tube for vibration to a vibrating member disposed therein; wherein two ends of a conducting cable formed the coil are directly connecting to a jack of an earphone or a headphone of outputting an audio signal, and the conducting part on the audio signal outputted from the jack is conducting the vibration of the coil through the tube to output a sound from the vibrating member.
