Method for Controlling Earphone Switching and Earphone

An earphone, comprising:

• at least one processor;
• and
• a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, causes the at least one processor to carry out actions comprising:
• acquiring a first remaining power and a first operating parameter of the earphone and a second remaining power and a second operating parameter of other earphone, the earphone being configured to be coupled with an electronic device and the other earphone and serving as a master earphone, and the other earphone serving as a slave earphone;
• predicting a first battery life of the earphone according to the first remaining power and the first operating parameter;
• predicting a second battery life of the other earphone according to the second remaining power and the second operating parameter;
• and
• switching the other earphone to serve as the master earphone and the earphone to serve as the slave earphone, when a difference between the second battery life and the first battery life is greater than a first preset threshold.

An earphone system, comprising a first earphone and a second earphone with only one of them being capable of coupling with an electronic device at a time, the first earphone being currently coupled with the electronic device and the second earphone and comprising:

• at least one processor;
• and
• a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, causes the at least one processor to:
• acquire a first remaining power and a first operating parameter of the first earphone and a second remaining power and a second operating parameter of a second earphone;
• determine a first battery life of the first earphone according to the first remaining power and the first operating parameter;
• determine a second battery life of the second earphone according to the second remaining power and the second operating parameter;
• and
• disconnect a first data transmission link between the first earphone and the electronic device and establish a second data transmission link between the second earphone and the electronic device, when a difference between the second battery life and the first battery life is greater than a first preset threshold.
