HEADPHONE ON-HEAD DETECTION USING DIFFERENTIAL SIGNAL MEASUREMENT

摘要

A headset includes a first speaker coupled to a first compensation network and a second speaker coupled to a second compensation network. The headset also includes a differential sensing module configured to determine a differential signal between a first input signal associated with the first speaker and a second input signal associated with the second speaker. The differential signal is used to determine whether the headset is detected as worn by a user. A controller adjusts a power level supplied to the headset based on the differential signal.
