Embodiment Construction

[0180]FIG. 1 is a schematic illustration of a computer 20 and an electronic device 30, which are operative to communicate using sound waves, in accordance with a preferred embodiment of the invention. Most computers currently on sale include a sound system 24, usually a sound card, connected to at least one microphone 26 and at least one speaker 28. Many electronic devices include a microphone 34 and a speaker 36. In a preferred embodiment of the invention, computer 20 and electronic device 30 communicate using these standard components, which are usually not designed for computer communication but for human communication. In some cases, the electronic device (or the computer) may include a jack to which one or more speakers and one or more microphones may be connected. Preferably, such connected acoustic elements are positioned on a difficult to obstruct portion of the device, preferably at positions where the elements have a wide field of view.
