Title: Sound wave communication of human body apparatus and method
Inventor: HWANG JUNG HWAN
IPC: H04B13/00
Filed: 2007-09-27
Abstract: A method and an apparatus for communicating a sound wave of a human body are provided to simply and efficiently communicate data among apparatuses contacting the human body by using a phenomenon of transmitting the sound wave through the human body. A sound wave converter(120) connected to an input/output unit(110) converts an electrical signal of output data into a sound wave, applies the sound signal to a human body(10), and converts the sound wave transmitted through the human body into an electrical signal. Here, the sound wave signal applied to the human body is transmitted from a part of the human body which contacts a first apparatus for communicating the sound wave of the human body to a part of the human body which contacts a second apparatus for communicating the sound wave of the human body and input into the second apparatus for communicating the sound wave of the human body. Since the input sound wave signal is converted into an electrical signal, again, data is communicated between the first and second apparatuses for communicating the sound wave of the human body. A switch(130) is connected to the sound wave converter and input and output ports of a data processor(140). The switch switches the input/output data by changing the switch to the input port or output port in response to a control signal generated by the data processor. In a case where there is data to be transmitted, the data processor outputs a data signal having an analog or digital form to the output port in an electrical signal form. At this time, the data processor generates a control signal and changes the switch so as to connect the output port to the sound wave converter. In addition, in a case where there is a sound wave signal to be transmitted through the human body, the data processor generates a control signal and changes the switch so as to connect the data processor to the input port. The sound wave converter receives the converted electrical signal. The apparatus for communicating the sound wave of the human body according to the first embodiment of the present invention communicates data through the human body.
