1. An electronic device comprising:
- a speaker;
a digital audio player to drive the speaker; and
a magnetic field signature generator to drive the speaker in accordance with a magnetic field signature signal that is encoded with an identification value of the electronic device so that the speaker can produce a change in a local magnetic field of the electronic device in order to produce a magnetic field signature that is detectable by an electronic compass in a nearby portable electronic device and that identifies the electronic device for purposes of network device discovery.

Abstract
A compass output in a first portable electronic device is monitored as the first device and a second electronic device come closer to each other. It is determined, by a process running in the first device, whether a magnetic field signature that is based on the monitored compass output is associated with a previously defined type of electronic device with which a network device discovery process is to be conducted. Other embodiments are also described and claimed.

8. A method for creating a magnetic field signature in an electronic device, comprising:
-
receiving a magnetic field signature signal that is encoded with an identification value of the electronic device; driving a speaker in accordance with the magnetic field signature signal, thereby changing a local magnetic field that is detected by an electronic compass in a portable electronic device when the electronic device is sufficiently proximate to the portable electronic device; and performing a network device discovery process with the portable electronic device, in response to the portable electronic device having detected the local magnetic field as identifying said electronic device. - View Dependent Claims (9, 10, 11)
