Claim:
1. A system, comprising: a sound-producing device that includes a power source, an audio transducer, a digital controller, and a first electronic coupling member, the digital controller coupled to the power source and having an input coupled to the first electronic coupling member and an output coupled to the audio transducer; and an external interface comprising signal conversion circuitry and a second electronic coupling member, the signal conversion circuitry configured to convert a first audio-encoded signal to a conditioned audio-encoded signal, the conditioned audio-encoded signal being compatible with the sound-producing device but the first audio-encoded signal not being compatible with the sound-producing device, and wherein the second electronic coupling member is configured to removably mate with the first electronic coupling member; wherein the power source in the sound-producing device powers the signal conversion circuitry in the external interface through the first and second electronic coupling members; and wherein the external interface provides the conditioned audio-encoded signal to the sound-producing device through the first and second electronic coupling members.
