Abstract
Disclosed are an in-ear detection method for a wireless earphone and a wireless earphone. This method includes acquiring a position parameter sent by a position detection module; determining that the wireless earphone has left a charging box based on the position parameter; controlling an audio playback module to emit a detection acoustic wave; acquiring a detection signal and identifying acoustic parameters of the detection signal, the detection signal being generated from a reflected wave of the detection acoustic wave collected by an acoustic wave sensor; and determining whether the wireless earphone is worn in a user's ear based on the acoustic parameters.
