Abstract
Embodiments of the invention include methods, apparatus, systems and means for determining a type of microphone button of a headset plugged into a device jack are described. In some embodiments, a type of microphone button or headset is determined from a plurality of button or headset types based on whether or not a headset plug is detected in a headset jack of a device and whether or not a signal received at a first contact of the headset jack includes an overcurrent or an undercurrent. In some embodiments, the behavior of the device may be controlled based on the type of microphone button or headset determined. For example, a predetermined circuit, a predetermined algorithm, or a predetermined process may be selected to signal process the audio signal of the microphone, based on the type of microphone button or headset.
