Abstract
A circuit including headset type detection provides compatibility with different transducer types, such as headphones provided by different manufacturers. An audio circuit that generates or receives an audio signal includes electrical terminals for coupling to a transducer device, at least one of which carries the audio signal. A transducer device type detection circuit is included and detects a type of a transducer device coupled to the audio device from characteristics measured at the multiple electrical terminals when the transducer is coupled to the audio device. The circuit also includes a configuration control circuit for altering a configuration of the audio device according to a detected type of the transducer device.
