Method and apparatus to transmit audio into the human ear

摘要

Apparatus and method for generating an audio signal, comprising a first cylindrical electrode adapted to generate a first acoustic field and a first frequency generator coupled therewith. A second cylindrical electrode is positioned coaxially to the first cylindrical electrode and is adapted to generate a second acoustic field. An audio mixer drives the second cylindrical electrode with a modulated difference signal between a signal received from the first frequency generator and an input audio signal. The first and second acoustic fields exhibit an overlapping portion which generates an audible audio signal.
