Earphone work method and earphone

The invention discloses an earphone work method, comprising steps of controlling a micro-control unit inside the earphone to go into a low power consumption mode when detecting that working modules related to the audio frequency broadcasting in the earphone are started up, and wakening up the micro-control unit when the interrupt event is detected by a general input-output port of the micro-control unit. The invention also discloses an earphone. The earphone work method of the invention can effectively reduce the electric quantity loss of the micro-control unit without affecting the normal audio frequency playing of the earphone, and improves the audio frequency playing time. 本发明公开了一种耳机的工作方法，包括以下步骤：当检测到耳机中与音频播放相关的工作模块开启时，控制耳机中的微控制单元进入预设低功耗模式；当通过所述微控制单元的通用输入输出口检测到中断事件时，唤醒所述微控制单元。本发明还公开了一种耳机。本发明在不影响耳机正常音频播放功能的情况下，能有效地降低微控制单元的电量损耗，从而提高耳机的音频播放时间。
