WIPO Patent Application WO/2019/191950
Kind Code:
A1
Abstract:
The present invention pertains to the technical field of earphones, and in particular, to an earphones noise reduction method and apparatus, a master earphone, a slave earphone, and an earphones noise reduction system. The earphones noise reduction method is applied to the master earphone. The master earphone is wirelessly connected to the slave earphone. The master earphone comprises a first transducer, and the slave earphone comprises a second transducer. The master earphone and/or the slave earphone are wirelessly connected to an audio source device. The earphones noise reduction method comprises: acquiring a first ambient noise signal collected by the first transducer; receiving, based on wireless communications, a second ambient noise signal collected by the second transducer; and generating a first noise cancellation signal according to the first ambient noise signal and the second ambient noise signal.
