Abstract: An earphone control method, an earphone control system and an earphone. The earphone control method includes: selecting a motion state judgement parameter of a wearer for controlling an earphone and setting an alert condition according to the selected motion state judgement parameter; real-timely monitoring and acquiring behavior data of the earphone wearer; calculating the motion state judgement parameter by using the acquired behavior data to obtain a motion state judgement parameter value; and judging whether or not the motion state judgement parameter value satisfies the alert condition; if the motion state judgement parameter value satisfies the alert condition, determining to enter an earphone alert state and controlling to perform corresponding alert operation on the earphone.

Abstract: The present invention discloses a method and an apparatus for measuring a posture angle of an object. The method comprises the following steps: arranging a sensor in a measured object, the sensor being used for measuring characteristic quantities of magnetic field in three dimensional directions; actuating the sensor at the beginning of the measurement, and acquiring, by using the sensor, a current measured value of the characteristic quantity of magnetic field of the measured object in a carrier coordinate system; acquiring reference values of the characteristic quantities of magnetic field of the measured object in a geographic coordinate system; and calculating a current posture angle of the measured object according to numerical values of the characteristic quantities of magnetic field indicated by the reference value and the measured value in each direction respectively.
