Document Type and Number:
WIPO Patent Application WO/2016/155528
Kind Code:
A1
Abstract:
A method for a terminal to detect a headset status, and the terminal. A processor closes a passage for performing an audio signal output on a second headset, detects electrical signals of a first audio output end and a third audio output end of a first headset, then determines the frequency value of a low frequency resonance point of the first headset according to the electrical signals of the first audio output end and the third audio output end, and judges whether the first headset is in an in-place status according to the frequency value of the low frequency resonance point. As long as the electrical signals of a first audio output end and a third audio output end are detected, whether a headset is in place can be determined according to the change of the electrical signals. Thus, the status of a first headset can be detected simply and quickly.
