Abstract
Disclosed are a noise reduction method for a microphone array of an earphone, an apparatus, and an earphone comprising: acquiring, when an earphone wearer speaks, a first sound signal collected by a bone conduction microphone arranged on the earphone and second sound signals collected respectively by a preset number of microphones arranged on the earphone; determining, according to the first sound signal and the second sound signal, a delay time from a time when the voice signal arrives at each microphone to a time when the voice signal arrives at the bone conduction microphone; computing, according to the delay time, a pointing angle of the microphone array formed by the microphones relative to the wearer's mouth; and adjusting a beam pointing angle of the microphone array according to the pointing angle, such that the microphone array forms a beam by an adjusted beam pointing angle.
