Non-wireless communication using sound
First Claim
1. Apparatus for use in a first device to receive digital data non-wirelessly from a second device and to transmit digital data non-wirelessly to the second device, the apparatus comprising:
- a single jack configured to couple to either one of a headphone or a headset and to receive analog signals encoded with the digital data from the second device and to transmit analog signals encoded with digital data to the second device;
a first conversion unit coupled to the single jack and configured to encode digital data into analog signals for transmission to the second device; and
a second conversion unit coupled to the single jack and configured to recover the digital data from the analog signals received from the second device;
wherein the first device is one of a mobile phone, a personal digital assistant or a smart phone and wherein the second device is one of a mobile phone, a personal digital assistant or a smart phone.

Abstract
Method and apparatus are disclosed to allow non-wireless transmission or reception of data from one device to at least another device. More particularly, in one embodiment, a jack of a first device is configured to receive incoming analog signals encoded with digital data from the second device and to transmit outgoing analog signals encoded with digital data to the second device. The first device may also comprise a first conversion unit configured to encode digital data into the outgoing analog signals and a second conversion unit configured to recover digital data from the incoming analog signals.
