本发明的实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
如图1和图2所示，本发明实施例提供了一种耳机电路结构，包括：充放电装置101、用电装置103和耳机插头107；其中，充放电装置101和用电 装置103均电连接到耳机插头107上。
需要说明的是，本发明实施例耳机电路结构还可以包括：麦克风104、左听筒105、右听筒106中的部分或全部，例如、仅包括：麦克风104和左听筒105，或仅包括左听筒105和右听筒106。
该实施例中，通过设置一充放电装置101，一方面能够为耳机电路结构中的其他器件进行供电，或者对与之连接的终端设备进行充电，另一方面还可以通过终端设备向该充放电装置进行充电。该耳机电路结构的充放电状态和音频状态可以同时进行，并且相互之间不会产生影响。
可选地，如图3所示，耳机插头107包括：连接充电线的充电触点1071、连接左声道线的左声道触点1072、连接右声道线的右声道触点1073、连接麦克风线的麦克风触点1074和连接接地线的接地触点1075，且在充电触点1071与左声道触点1072之间、左声道触点1072与右声道触点1073之间、右声道触点1073与麦克风触点1074之间以及麦克风触点1074与接地触点1075之间均设有一绝缘环1076。
充电触点1071连接一充电线，左声道触点1072连接左声道线，右声道触点1073连接右声道线，麦克风触点1074连接麦克风线，接地触点1075连接一接地线。
该实施例中的耳机插头107相比图4中的四段式耳机插头在左声道触点1072的闲置端增加了一个绝缘环和一个充电触点1071。该充电触点1071在耳机电路结构中连接一个充电线。充电线路(充电线和接地线)连接充放电装置101，或者直接通过该充电线路外接充放电电路，以使该耳机电路结构具备充放电功能。此外，还可以是在现有的耳机插头上不增加充电触点的设置，而是改用左声道触点或者右声道触点中的一个作为充电线路。
可选地，充放电装置101的一端通过充电线连接到充电触点1071，充放电装置101的另一端通过接地线连接到接地触点1075。用电装置103的一端通过充电线连接到所述充电触点1071，用电装置103的另一端通过接地线连接到接地触点1075。
该实施例中，充放电装置和用电装置分别单独连接至充电线路中，能够 保证充放电装置在放电状态时，用电装置可以从充电装置处获得电压；充放电装置在放电状态时，用电装置可以在与该耳机电路结构连接的终端设备处获得电压。
可选地，该耳机电路结构还包括：控制信号发生装置102；控制信号发生装置102的一端连接到充放电装置101上，控制信号发生装置102的另一端通过麦克风线连接到耳机插头107上。
该实施例中，控制信号发生装置102可以是按键或者滑块的形式，可以在充放电模式和音频模式之间进行切换。例如，当控制信号发生装置102发送能够和语音信号区别的信号A时，一方面，耳机电路结构中的充放电装置101根据信号A进入放电状态，同时终端设备根据信号A进入充电状态，这样耳机侧可以向终端设备侧进行充电；另一方面，充放电装置可以直接向用电装置103供电。当控制信号发生装置102发送信号B时，一方面，充放电装置101根据信号B进入充电状态，同时终端设备根据信号B进入放电状态，这样终端设备侧可以向耳机侧进行充电；另一方面，终端设备向用电装置103供电。当控制信号发生装置102发送语音信号时，麦克风可以进入语音状态。该方案中的耳机电路结构实现了自身的蓄电功能、向其他器件供电的功能以及向外界用电设备进行充电的功能。该耳机电路结构的充放电状态和音频状态可以同时进行，并且相互之间不会产生影响。
可选地，充放电装置101包括：控制电路1011、升降压电路1012和蓄电电池1013；其中，控制电路1011和升降压电路1012均连接到蓄电电池1013上；控制电路1011还连接于控制信号发生装置102和升降压电路1012；升降压电路1012连接到耳机插头107上。
可选的，控制电路1011的第一端子连接到蓄电电池的第一端子上，控制电路1011的第二端子连接到控制信号发生装置102的第一端子上，控制电路1011的第三端子连接到升降压电路1012的第二端子上。升降压电路1012的第一端子连接到蓄电电池1013的第二端子上，升降压电路1012的第三端子通过充电线连接到耳机插头107上，升降压电路1012的第四端子通过接地线连接到耳机插头107上。
该实施例中，蓄电电池1013用于存储电能，即在充放电装置101处于放 电状态时，提供电能；在充放电装置101处于充电状态时，存储电能。控制电路1011设置为对蓄电电池1013的电量进行采样，以及根据控制信号发生装置102发送的充电或放电信号，控制升降压电路1012在充电或放电模式之间切换。控制电路1011对应异常情况，例如：蓄电电池1013发热严重，电压过保护等情况时，可以进行对应的切断保护动作。
升降压电路1012设置为在充电状态时，通过降压电路将外接高电压转换为低电压进行充电；在放电状态时，通过升压电路将低电压转换为高电压进行放电。例如，升降压电路1012通过一控制器进行电压检测及充放电控制。在充电状态时，通过降压电路(电感线圈)将外接的高电压(例如：5伏(V)电压)降低为低电压(例如4.2V电压)进行充电，当蓄电电池1013的电压达到4.2V时停止充电。在放电状态时，通过升压电路将电压升高到5V进行放电(向终端设备或者用电装置供电)，当蓄电电池的电量低至保护值(例如：3V)时，结束放电。另外，还可以通过指示灯对蓄电电池的电量进行检测来控制显示，例如：第一灯亮时表示电量小于3.5V，第二灯亮时表示电量在3.5V～3.7V之间，第三灯亮时表示电量在3.7V～3.9V之间，第四灯亮时表示电量大于3.9V。
可选地，用电装置103包括：保护电路1031和用电电路1032；其中，
保护电路1031连接到耳机插头107上；用电电路1032连接到保护电路1031上。
可选的，保护电路1031的第一端子通过充电线连接到耳机插头107上，保护电路1031的第二端子通过接地线连接到耳机插头107上，保护电路1031的第三端子和第四端子均连接到用电电路1032上。
该实施例中，在用电电路1032获取充放电电压前加设保护电路1031，保护电路1031可以将该充放电电压进行转换，以免在充放电电压与用电电路1032的工作电压不一致时损坏用电电路1032。保护电路1031和用电电路1032直接与充电线路以及充放电装置101的输出端(充放电装置的第一端子和第二端子)同时连接，可以保证在充放电装置101处于放电状态时，该用电装置103能够从充放电装置101的输出端获得稳定的电压；在充放电装置101处于充电状态时，该用电装置103能够从充电线路获得稳定的电压。
如图5所示，本发明实施例提供了一种终端设备，包括上述的耳机电路结构。该终端设备还包括：耳机接口201、终端控制信号发生装置202和终端电池203；其中，耳机接口201和终端控制信号发生装置202均连接到终端电池203上；耳机接口201与终端控制信号发生装置202连接；耳机插头107***耳机接口201中。
该实施例中，通过将耳机插头107***耳机接口201中，实现耳机电路结构和终端设备之间的电路连接。终端控制信号发生装置202根据耳机电路结构中的控制信号发生装置102发送的充电信号，控制终端电池203向耳机侧进行充电；根据耳机电路结构中的控制信号发生装置102发送的放电信号，控制终端电池203通过耳机侧进行充电。
上述方案中，通过在耳机插头107上设置一充电触点1071并通过一充电线对应连接一充放电装置101，该耳机电路结构可以实现向终端设备侧进行充电，还可以向耳机电路结构中的其他器件供电，并且不影响耳机电路结构的音频状态。同时，终端设备侧也可以向该耳机电路结构进行充电。该方案可以实现充放电状态和音频状态同时进行。
以上所述的是本发明的可选实施方式，应当指出对于本技术领域的普通人员来说，在不脱离本发明所述的原理前提下还可以作出若干改进和润饰，这些改进和润饰也在本发明的保护范围内。
虽然本申请所揭露的实施方式如上，但所述的内容仅为便于理解本申请而采用的实施方式，并非用以限定本申请，如本发明实施方式中的具体的实现方法。任何本申请所属领域内的技术人员，在不脱离本申请所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本申请的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
工业实用性
上述技术方案实现了充放电状态和音频状态同时使用。
