Claim:
1. A method comprising: producing a first audio output from a first device; and producing an electromagnetic field from one or more coils of the first device, where the electromagnetic field is configured for at least partially producing a second audio output from a second device based upon one or more coils of the second device being in the presence of the electromagnetic field from the first device, and inductive coupling the one or more coils of the first device to the one or more coils of the second device, where information sent by the electromagnetic field is provided through the inductive coupling, where the information at least partially comprises an audio signal, where the electromagnetic field is configured to provide a relationship between the first and second audio outputs such that: when the first audio output is the first acoustic sound, producing the second audio output as the second acoustic sound from the second device at least partially based upon the information from the electromagnetic field, where the first acoustic sound constructively interacting with the second acoustic sound, where the constructive interacting provides a loudness from a combination of the first acoustic sound and the second acoustic sound which is louder than a loudness of the first acoustic sound from the first device alone, and buffering the first audio output in the first device to provide a delay between the first acoustic sound and the second acoustic sound.
