Earphone working mode switching method and device, audio circuit, earphone and earphone system

The present invention relates to the technical field of earphones, and in particular, to an earphone working mode switching method and device, an audio circuit, an earphone and an earphone system.Theearphone working mode switching method comprises: determining a current working mode of a first earphone and/or a second earphone; acquiring a relative motion state between the first earphone and thesecond earphone; and controlling switching of the current working mode of the first earphone and/or the second earphone according to the relative motion state. Therefore, without the participation ofbuttons, users can flexibly and quickly switch the working mode of the earphone, thereby improving the user experience. Moreover, it can also reduce the design cost and difficulty caused by designingthe buttons. 本发明涉及耳机技术领域，特别是涉及种耳机工作模式切换方法及装置、音频电路、耳机及耳机系统。其中，耳机工作模式切换方法包括：确定第耳机和/或第二耳机的当前工作模式；获取第耳机与第二耳机之间的相对运动状态；根据相对运动状态，控制第耳机和/或第二耳机的当前工作模式的切换。因此，无需按键的参与，用户便可以灵活快速地切换耳机的工作模式，从而提高用户体验感。并且，其还可降低因设计按键而带来的设计成本与困难。
