在一个实施例中，当第一开关600闭合时，控制单元300的第一端301侦测到低电平，控制单元300不作任何输出，第一开关600对应的第一电阻400与手机内部电路分压；当第二开关800闭合时，控制单元300的第三端303侦测到低电平，控制单元300不作任何输出，第二开关800对应的第二电阻700与手机内部电路分压。手机根据第一电阻400或第二电阻700分压所得的电压值辨别闭合的是第一开关600还是第二开关800，实现一种操作***（例如Android）的耳机音量调节、或上一曲和下一曲等功能。
当第一开关600或第二开关800从闭合状态变为断开状态的瞬间，控制单元300的第一端301或第三端303侦测到高电平，此时，控制单元300输出预设编码脉冲信号。
当第一开关600断开时，控制单元300输出大约116KHz的编码脉冲信号；当第二开关800断开时，控制单元300输出大约154KHz的编码脉冲信号。滤波单元200把控制单元300输出的编码脉冲信号叠加到主电路上反馈给连接耳机的手机，手机根据编码脉冲信号辨别第一开关600或第二开关800的操作，实现另一操作***（例如IOS）的耳机音量调节、或上一曲和下一曲等功能。

同理，当第二开关800闭合时，控制单元300的第三端303侦测到低电平，第二开关800对应的第二电阻700与手机内部电路分压，Android操作***的手机根据第二电阻700分压所得的电压值辨别第二开关800闭合的动作从而作出响应；控制单元300产生频率为270KHz（0.9ms）+ 165KHz（1.8ms）的第一预设编码脉冲信号反馈给连接该耳机线控装置的Android操作***的手机，Android操作***的手机无法识别该第一预设编码脉冲信号从而不作任何响应。
Android操作***的手机根据第一电阻400或第二电阻700分压所得的电压值辨别闭合的是第一开关600还是第二开关800，实现一种操作***Android的耳机音量调节、或上一曲和下一曲等功能。
当第一开关600或第二开关800断开时，即从闭合状态变为断开状态的瞬间，控制单元300侦测到高电平，控制单元300输出频率为270KHz （0.9ms） +95KHz（1.8ms）的第二预设编码脉冲信号，Android操作***的手机无法识别该第二预设编码脉冲信号从而不作任何响应。
在本实施例中，举例说明，耳机连接到iOS操作***的手机，在耳机***手机的瞬间，控制单元300会产生频率为270KHz（0.9ms）+ 130KHz（5.5ms）的编码脉冲信号发送给手机，以用于耳机初始化。
当第一开关600闭合时，控制单元300的第一端301侦测到低电平，控制单元300产生频率为270KHz（0.9ms）+ 130KHz（1.8ms）的第一预设编码脉冲信号发送给连接该耳机线控装置的iOS操作***的手机，iOS操作***的手机识别到该第一预设编码脉冲信号从而作出响应；第一开关600对应的第一电阻400与手机内部电路分压，iOS操作***的手机无法识别第一电阻400分压所得的电压值从而不作任何响应。
同理，当第二开关800闭合时，控制单元300的第三端303侦测到低电平，控制单元300产生频率为270KHz（0.9ms）+ 165KHz（1.8ms）的第一预设编码脉冲信号反馈给连接该耳机线控装置的iOS操作***的手机，iOS操作***的手机识别到所述编码脉冲信号从而作出响应；第二开关800对应的第二电阻400与手机内部电路分压，iOS操作***的手机无法识别第二电阻700分压所得的电压值从而不作任何响应。

当第一开关600或第二开关800断开时，即从闭合状态变为断开状态的瞬间，控制单元300侦测到高电平，控制单元300输出频率为270KHz （0.9ms） +95KHz（1.8ms）的第二预设编码脉冲信号。滤波单元200把控制单元300输出的第二预设编码脉冲信号叠加到主电路上发送给连接耳机的手机，手机根据编码脉冲信号辨别第一开关600或第二开关800的操作结束，即耳机音量调节、或上一曲和下一曲等功能的操作结束。
在上述实施例中，第一二极管500的作用非常重要，当第一开关800闭合时，第二电阻700与手机内部电路分压，控制单元300的第三端303为低电平，如果没有第一二极管500，将导致控制单元300的第一端301也变成低电平，从而引起误动作。
如图2所示，其为另一实施例中的耳机线控装置的结构示意图。在该实施例中，供电管理单元100包括第二二极管D2和第一电容C1，其中，第二二极管D2的正极与电源相连，第二二极管D2的负极和第一电容C1的一端相连，第一电容C1的另一端接地。第一电容C1可以由两个电容并联组成。
