- The present invention relates to a sound transmission system using a human body as a propagation medium. The transmission system includes a first signal transmitter and a second signal transmitter respectively generating signals having frequencies corresponding to each other, the first and second signal transmitters being coupled to the human body, wherein the first and second signal transmitters respectively generate high frequency signals having an opposite phase to each other, and the respective signal transmitters combine the audio signals and the high frequency signals to transmit the combined signals to the human body. The respective signal transmitters combine the generated audio signals and high frequency signals, adjust an output phase of the combined signals, and transmit the combined signals through the human body.
