Abstract:
A method for producing sound, comprising the steps of:providing a base unit having a signal output portion adapted to be positioned in use in contact with or in close proximity to the surface of a user's body, and a reception unit for mounting adjacent the user's ear(s),locating the signal output portion in contact with or in close proximity to the surface of the user's body,applying a radio-frequency signal, modulated with an audio signal, to the signal output portion of the base unit,transmitting the radio-frequency signal from the signal output portion into the user's body,locating the reception unit in contact with or in close proximity to the user's head,receiving the radio-frequency signal from the base unit at the reception unit after transmission substantially solely through the user's body,demodulating the received signal with the reception unit to extract the audio signal therefrom, andgenerating sound adjacent the user's ear(s) from the audio signal.
