具体实施方式
本实施例为本发明优选实施方式，其他凡其原理和基本结构与本实施例相同或近似的，均在本发明保护范围之内。
本发明为一种超低功耗待机的蓝牙装置的实现方法，其方法为在蓝牙装置主体上设有触发开关，蓝牙装置不使用时，通过触发开关触发深度睡眠控制引脚，使蓝牙装置处于深度睡眠状态；蓝牙装置使用时，通过触发开关唤醒深度睡眠模式，蓝牙装置处于正常使用状态。
请参看附图1、附图2和附图3，本发明主要包括了蓝牙耳机主机1和开关装置两大部分，本实施例中，开关装置采用底座2。本实施例中，底座2上设有一个容置槽8，用于放置蓝牙耳机主体1，底座2上设有一个盖体3，盖体3可旋转，当蓝牙耳机主体1放入容置槽8内时，翻转盖体3，将蓝牙耳机主体1挡住，防止其脱出，本实施例中，蓝牙耳机主体1顶部固定设有一个限位环4，盖体3上对应于限位环4位置处开有通孔9，当盖体3盖合时，限位环4设置在通孔9内，将其卡住。本实施例中，在底座2和蓝牙耳机主体1分别固定设有磁铁（图中未画出），可通过磁铁的吸合将底座2和蓝牙耳机主体1配合在一起，使底座2和蓝牙耳机主体1上的触点相处接触。本实施例中，底座2和蓝牙耳机主体1通过3个触点相互接触，其中，蓝牙耳机主体1上的触点分别包括蓝牙耳机out_contact触点5、蓝牙耳机MCU_charger触点7和蓝牙耳机GND触点6，底座2上的触点分别包括底座out_contact触点12、底座charger_5v触点10和底座GND触点11。
请结合参看附图6和附图7，本实施例中，在蓝牙耳机主体1和底座2内分别设有控制电路，蓝牙耳机主体1内的控制电路主要包括蓝牙模块、低电平触发超低功耗开关模块和高电平触发复位开关模块，蓝牙模块主要为蓝牙芯片，蓝牙耳机主体1内还设有给蓝牙芯片供电的内置锂电池，其中，低电平触发超低功耗开关模块连接在蓝牙模块的深度睡眠控制引脚，高电平触发复位开关模块连接在蓝牙模块的ON/OFF端，开关装置控制低电平触发超低功耗开关模块和高电平触发复位开关模块工作。本实施例中，低电平触发超低功耗开关模块包括MOS管Q7和电容C15，MOS管Q7和电容C15串联连接，MOS管连接到正电源端，电容C15连接到蓝牙模块的深度睡眠控制引脚，MOS管Q7的触发端与开关装置连接。高电平触发复位开关模块包括电容C16、三极管Q1和三极管Q8，电容C16一端连接在开关装置上，电容C16另一端连接在三极管Q8的基极上，三极管Q8一端接地，另一端与三极管Q1的基极连接，三极管Q1一端与正电源连接，另一端连接在蓝牙模块的ON/OFF端。本实施例中，蓝牙耳机主体1内out_contact触点5与低电平触发超低功耗开关模块和高电平触发复位开关模块电连接，即out_contact触点5分别与电容C16和MOS管Q7的触发端（即栅极）连接，GND触点6接地，MCU_charger触点7给主体的内置锂电池充电，底座2内的out_contact触点12通过电阻R5与GND触点11连通，charger_5v触点10与充电输出接口电连接。
请参看附图4，本发明在使用时，当蓝牙耳机主体1放到底座2上后，盖上盖体3即可，此时，蓝牙耳机主体1和底座2上的触点会通过里面的磁铁吸附住，而相互导通，蓝牙耳机主体1上的三个触点out_contact，MCU_charger和GND，分别与底座2上的三个触点out_contact，charger_5v和GND相接触，。其中charger 5V只是给耳机电池充电用的。蓝牙耳机主体1和底座2上的两个out_contact触点相连通时，使得蓝牙耳机主体1内的out_contact触点处被拉到低电位，MSO管Q7的G脚也同时为低电位，此时MOS管Q7会处于导通状态。由于电容C15的瞬变作用，在PIO8端口处会产生一个3.7v的正向脉冲，PIO8端口是直接连到主蓝牙芯片的深度睡眠控制引脚上，当蓝牙芯片收到PIO8端口送来的正脉冲后，蓝牙芯片会自动进入深度睡眠模式，此时的待机电流为0.5uA，达到超低功耗的目的。
请参看附图5，本发明正常使用时，翻开盖体3，从底座2上拿起蓝牙耳机主体1触点断开后，蓝牙耳机会自动进入开机正常模式。只要将蓝牙耳机主体1从底座2上拿起来后，蓝牙耳机主体1内的out_contact触点变为高电位，由于电容C16的瞬变作用，在三极管Q8的B极（即积极）会有一个高脉冲使三极管Q8导通，此时，在三极管Q1的B极（即积极）为低电位，使得三极管Q1同时导通，于是ON/OFF端点也会有一个3.7V的正脉冲，ON/OFF端是直接连接到蓝牙耳机的开机脚位上的，蓝牙耳机收到来自ON/OFF端的高电位脉冲后，蓝牙耳机会自动唤醒深度睡眠模式，进入正常的开机连通电话的功能。
本发明在蓝牙耳机上使用50MAH的电池的时候，其待机电流为0.5uA，理论待机时间可以达到2500小时，折合104天，在蓝牙耳机上使用新型技术后，待机时间可从4天增加到104天，提高了100天的待机时间，大大降低了充电频率，增加了使用方便性。
