Portable audio listening apparatus
First Claim
1. A portable audio listening apparatus comprising:
- a transmission apparatus and a portable receiving apparatus electrically and mechanically structured as different units,the portable transmission apparatus comprising;
means for generating an audio modulated signal modulated in a band in which a signal is transferred by using a human body of a single user, wherein the audio modulated signal is generated based on stored audio data; and
a first electrode for outputting the generated audio modulated signal, andthe portable receiving apparatus comprising;
a second electrode for receiving the audio modulated signal transferred through the first electrode and then through the body of the single user;
means for demodulating the audio modulated signal received by the second electrode and downloading said demodulated signal into said audio listening apparatus for storage; and
means for generating audible sound according to the stored demodulated signal;
wherein said second electrode is adapted to receive the audio module signal sent from an audio-signal transmission apparatus, wherein the portable receiving apparatus further comprises a transmitter for transmitting a second audio modulated signal through the body of the single user; and
wherein the portable audio listening apparatus includes a second portable receiving apparatus, wherein the second portable receiving apparatus includes;
a third electrode for receiving the second audio modulated signal transferred through the body of the single user;
second means for demodulating the second audio modulated signal received by the third electrode; and
second means for generating audible sound according to the demodulated second audio modulated signal.

Abstract
A portable audio listening apparatus includes, for example, a portable audio playback apparatus serving as a portable transmission apparatus and a headphone serving as a portable receiving apparatus. The portable audio playback apparatus has an electrode at its side. The headphone includes an ear pad made from an electrically conductive material and an electric-circuit unit. The ear pad serves as an electrode and is connected to the electric-circuit unit by wiring. The electric-circuit unit includes a signal processing circuit and a battery. When the user wears the portable audio playback apparatus and the headphone, a transmission path is formed through the body of the user. A signal reproduced by the portable audio playback apparatus is sent through the body of the user and the ear pad to the electric-circuit unit of the headphone.
