The invention claimed is: 1. A method of communicating with an electronic device, comprising: providing an electronic device having an audible sound receiving and generating sub-system including a microphone; transmitting from an electronic source at least one acoustic signal encoded with information; receiving said at least one acoustic signal by said microphone; extracting said encoded information by the electronic device or by a different device that received a representation of the at least one acoustic signal from the electronic device; and determining at least one of a spatial position, distance or movement of the microphone relative to the source, responsive to the at least one acoustic signal encoded with information. 2. A method according to claim 1, comprising transmitting to said source, using a loudspeaker associated with the electronic device, at least a second acoustic signal, encoded with information, in response to said received acoustic signal. 3. A method according to claim 2, wherein at least one of said at least one acoustic signal and at least a second signal comprise an ultrasonic signal. 4. A method according to claim 1, wherein said electronic device comprises a computer. 5. A method according to claim 4, wherein said source comprises a computer peripheral. 6. A method according to claim 5, wherein said peripheral comprises a printer. 7. A method according to claim 4, wherein said computer comprises a personal digital assistant (PDA) or a portable computer. 8. A method according to claim 1, comprising extracting said encoded information by the electronic device. 9. A method according to claim 1, wherein determining a spatial position, distance or movement comprises determining a distance between said microphone and said source. 10. A method according to claim 1, wherein determining a spatial position, distance or movement comprises determining movement of said microphone relative to said source. 11. A method according to claim 9, wherein said movement comprises angular movement. 12. A method according to claim 1, wherein determining at least one of a spatial position, distance or movement comprises determining a spatial position of said microphone relative to said source. 13. A method according to claim 12, wherein said spatial position is a one-dimensional spatial position. 14. A method according to claim 12, wherein said spatial position is a two-dimensional spatial position. 15. A method according to claim 12, wherein said spatial position is a three-dimensional spatial position. 16. A method according to claim 1, wherein the source comprises a pointing implement and comprising emulating a touch screen or pointing device behavior on a screen of the electronic device responsive to the received at least one acoustic signal. 17. A method according to claim 1, wherein said source comprises a toy. 18. A method according to claim 17, comprising controlling at least one action of the toy, responsive to said received at least one acoustic signal. 19. A method according to claim 1, wherein said information comprises music. 20. A method according to claim 1, wherein said information comprises personal information. 21. A method according to claim 1, wherein said source comprises a smart card. 22. A method according to claim 1, wherein said source comprises a computer. 23. A method according to claim 1, comprising logging into a computer system responsive to said received at least one acoustic signal. 24. A method according to claim 1, wherein said acoustic signal comprises human audible sound. 25. A method according to claim 24, wherein said acoustic signal has a main frequency over 10 kHz. 26. A method according to claim 1, wherein said acoustic signal has a main frequency which is infra-sonic. 27. A method according to claim 1, wherein said information is encoded on the acoustic signal using below human-threshold amplitudes. 28. A method according to claim 1, wherein said information is encoded using below human-threshold amplitude variations. 29. A method according to claim 1, wherein said acoustic signal has a main frequency below 50 kHz. 30. A method according to claim 1, wherein said acoustic signal has a main frequency below 25 kHz. 31. A method according to claim 1, comprising retransmitting said acoustic signal to a remote computer which analyses said received acoustic signal to determine information encoded by said acoustic signal. 32. A method according to claim 1, wherein transmitting the at least one acoustic signal encoded with information comprises transmitting a signal encoded using at least one of AM, FM, PSK, QPSK, pulse length encoding, frequency modulation, Pulse Width Modulation and On-Off Keying. 33. A method according to claim 1, wherein extracting the encoded information comprises performing one or more of: demodulating the encoded information into bits; and error checking using an error detection code. 34. A method according to claim 1, wherein the at least one acoustic signal is encoded according to a digital binary code. 35. A method according to claim 1, wherein the at least one acoustic signal includes an error detection code. 36. A method according to claim 1, further comprising: a step of transmitting an RF signal, said transmission of the RF signal being simultaneous with said transmission of the at least one acoustic signal; and a step, before said step of determining, of receiving the RF signal by said microphone; wherein said step of determining comprises determining the distance between the microphone and the source, based on the delay between said step of receiving the RF signal and said step of receiving the at least one acoustic signal. 37. A method according to claim 36, wherein the at least one acoustic signal and the RF signal are generated by a single device. 38. A method according to claim 37, wherein said single device comprises a computer speaker. 39. A method according to claim 36, wherein the at least one acoustic signal and the RF signal are generated by separate devices. 40. A method according to claim 39, wherein the at least one acoustic signal and the RF signal are generated by a computer speaker and a BlueTooth RF link, respectively. 41. A method according to claim 36, wherein the at least one acoustic signal and the RF signal are detected by a microphone on a smart card.
