Human body sound transmission system and method for transmitting a plurality of signals

A human body sound transmission method, comprising:

• generating a sound signal and a high frequency signal;
• generating high frequency sound signal by synthesizing the sound signal with the high frequency signal;
• coupling the high frequency sound signal with the high frequency signal;
• amplifying the coupled signal;
• generating a plurality of signals having the same magnitude, phase, and frequency as the amplified signal;
• and
• applying the plurality of signals to the human body,
• wherein a magnitude of the sound signals recovered around a human's ear is increased in proportion to the number of signals transmitted through the human body by transmitting the plurality of signals including the same sound signals through the human body.

A human body sound transmission method, comprising:

• generating sound signal and high frequency signal;
• generating a plurality of sound signals and a plurality of high frequency signals that are the same as the sound signal and the high frequency signal;
• generating a plurality of high frequency sound signals by synthesizing the plurality of sound signals with the plurality of high frequency signals, respectively, by using different signal synthesizing methods;
• coupling the plurality of high frequency sound signals with the plurality of high frequency signals, respectively;
• amplifying the plurality of coupled signals;
• and
• applying the plurality of amplified signals to the human body, respectively.
