METHOD AND DEVICE FOR AUTOMATICALLY SWITCHING MASTER-AND-SLAVE RELATIONSHIP OF WIRELESS EARPHONES AND WIRELESS EARPHONES

Document Type and Number:

WIPO Patent Application WO/2019/090539

Kind Code:

A1

Abstract:

A method and device for automatically switching a master-and-slave relationship of wireless earphones, and wireless earphones. Because a first wireless earphone and a second wireless earphone each has an MAC address and a key of the other stored therein, scanning connection can be performed between the first wireless earphone and the second wireless earphone. Further, because the first wireless earphone and the second wireless earphone each has an MAC address and a key of the same terminal device stored therein, the first wireless earphone and the second wireless earphone can be separately connected with the terminal device. Therefore, either the first wireless earphone or the second wireless earphone can be used as a master earphone or a slave earphone. When the master earphone is power-off, the slave earphone can be switched as a master earphone for continuous use. When one of the first wireless earphone and the second wireless earphone is first connected with the terminal device, the connected wireless earphone is set as a master mode, and the other wireless earphone connected afterwards is switched to a slave mode; therefore, a user does not need to distinguish a master earphone from a slave earphone.
