Head posture detection method and apparatus, and earphone

Abstract

The invention discloses a head posture detection method and apparatus, and an earphone. The method comprises the following steps: separately obtaining acceleration data collected by an acceleration sensor and a magnetic field data collected by a magnetic sensor at the same moment; using the acceleration data and the magnetic field data at the same moment to calculate a posture angle at the moment; judging whether a head posture is abnormal according to the posture angle; and if the head posture is abnormal, sending a head posture abnormality instruction to a motor in the earphone, so that the motor performs vibration prompting according to the head posture abnormality instruction. In the technical scheme of the invention, the acceleration data and the magnetic field data can be accurately collected by directly using the acceleration sensor and the magnetic sensor, the backswing error of a gyroscope is avoided, the head posture detection accuracy of the user is improved, the cost and the power consumption of the earphone are reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a head posture detection method, device and earphones. Background technique [0002] In modern life, wearing earphones has become a daily living habit of users. For example, on the way to work, wearing earphones to listen to music or news can make full use of time. However, when the user wears the earphone, the user often has a bad posture, which brings bad consequences. For example, in a public place, shaking his head constantly with the music played in the earphone will cause a bad public image on the one hand, and on the other hand. On the one hand, it is not conducive to the physical and mental health of users. Therefore, there is a need for an earphone that detects the user's head posture, so that when the user is in an incorrect head posture, the user is reminded to make adjustments in time. [0003] The head attitude detection technology of the earphone in the prior ar...

AI Technical Summary

Problems solved by technology

However, due to the back-swing phenomenon of the gyroscope itself, the inaccuracy of the head posture detection is caused, and the cost and power consumption are relatively large.

If the selected time threshold is 3s, the measurement result is inaccurate due to the error of the gyroscope itself in the first 1-2 seconds, which will affect the solution or analysis result
