Bluetooth earphone of auto-switch terminal application program

The invention discloses a Bluetooth earphone for automatically starting/closing a terminal application program, and a method. The invention provides a method for automatically closing the terminal application program, comprising the steps as follows: induction signals are obtained every prearranged first time interval, whether the Bluetooth earphone is disconnected is judged according to the induction signal; if so, whether the terminal closes the audio playing application program is judged; if not, a closing signal is sent to the terminal. The embodiment of the invention also provides a method used for automatically starting the terminal application program, comprising the steps as follows: induction signals are obtained every prearranged first time interval, whether the Bluetooth earphone is disconnected is judged according to the induction signal; if not, whether the terminal closes the audio playing application program is judged; if so, a starting signal is sent to the terminal. Furthermore, the invention also provides the Bluetooth earphone which can automatically start or close the terminal application program. The Bluetooth and the method of the invention judge the disconnection state of the earphone by the induction signal, thus achieving the beneficial effects of automatically starting/closing the terminal application program by the Bluetooth earphone and reducing thepower dissipation.
