Abstract (en)
A method for identifying an accessory coupled to an electronic device. The method includes applying at least one detection pulse to the audio accessory, each detection pulse being spectrally shaped to be generally inaudible to a human user, receiving at least one response signal corresponding to each detection pulse that is indicative of the impedance of the accessory, and based on the impedance, identifying the accessory.
