背景技术
耳机是手机等常用电子设备最为重要的配件之一。越来越多的人们习惯在嘈杂的环境（例如在公交车上、火车上或其他交通工具）中利用手机等智能终端来打电话、听音乐或看视频等，都需佩戴耳机以隔离外界噪声，导致对降噪耳机的需求迅速增长。
不同于普通的耳机，降噪耳机在现有的耳机插头与音频播放单元之外，还设置有用于消除噪声的噪声消除模块。这类噪声消除模块需要使用专门的电源，该等电源通常包含电池和电压转换与稳压电路，使降噪耳机的外形尺寸、重量和成本与普通耳机相比均有所增加。同时，常用的电池提供的电压一般并不适合直接驱动这类噪声消除模块，因此还需要设置电压转换电路来将电池提供的电压调整到适合噪声消除模块使用的范围，这就更加造成了降噪耳机结构的复杂化，导致零部件数量较多、不易大规模生产、成本较高，且用户使用携带不方便等诸多问题。

具体实施方式
下面结合附图和实施例对本发明作进一步的说明。
本发明的实施例1：一种用电子设备的电源向降噪耳机供电的方法，在电子设备的耳机插座内或电子设备的PCB电路板上设置电源接脚，在降噪耳机的耳机插头上设置电源端，通过电源接脚将耳机插头上的电源端与电子设备的电源相连接，以利用所述电子设备的电源向降噪耳机的噪声消除模块供电。
在电子设备中设置控制装置，通过控制装置打开或关闭电子设备的电源对电源接脚的电源输出，对应地激活或停用与电源接脚连接的包括噪声消除模块的降噪耳机。通过控制装置设置及调节与电源接脚连接的包括噪声消除模块的降噪耳机的工作参数。
所述电子设备为手机、个人电脑、笔记本电脑、平板电脑、音乐播放器、视频播放器、多媒体播放器、便携式游戏机中的任意一种。
一种实现上述方法所使用的设备，包括降噪耳机和电子设备90，如图1、图2、图3、图4及图7所示，降噪耳机包括耳机插头10、音频播放单元50及噪声消除模块60，音频播放单元50和噪声消除模块60均与耳机插头10连接，耳机插头10用于插入耳机插座20的插孔27，与麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25依照上述方式连接以传输音频信号，音频播放单元50包括扬声器，用于播放耳机插头10传来的音频信号。噪声消除模块60装设于所述音频播放单元50中；噪声消除模块60用于消除外界的噪音，使耳朵听到的外来的环境噪音大大降低，达到令人满意的收听效果。具体地，该噪声消除模块60包括相互电性连接的噪声消除单元61和音频放大器62。该噪声消除单元61包括噪声消除电路，用于把与外界噪声信号相位相反的除噪信号叠加在耳机插头10接收到的音频信号上，使耳朵听到的外界噪声大大降低，从而能更加清楚地听到耳机插头10接收到的音频信号经由音频播放单元50播放出的声音。该音频放大器62用于对噪声消除单元61从耳机插头10接收到的音频信号进行预定倍数的放大，再将放大后的音频信号传输到音频播放单元50进行播放，以获得更好的音频信号播放质量。
如图11所示，该耳机插头10包括柱状的插头本体11，用于插入电子设备90例如手机的耳机插座。该插头本体11的外表面上设置有多个用于建立不同类型电性连接的连接端，按照从插头本体11基部到插头本体11顶端的顺序依次为麦克风端12、公用回路端13、右声道端14、左声道端15和电源端16。其中麦克风端12、公用回路端13、右声道端14、左声道端15的设置顺序与目前一种常用的四段式耳机插座制式（以下简称第一制式）是相同的。因此，如图9所示，本发明的耳机插座20的麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25能够按照现有方式与采用该第一制式的耳机配合使用。这样，该耳机插座20即可兼容上述耳机插头10与现有的采用该第一制式的耳机。
该降噪耳机的主要改进在于电源端16，该电源端16设置于插头本体11的顶端（即最前端），在所述插头本体11插入电子设备90的耳机插座20时与电子设备90的电源91（例如电池）连接，以从电子设备90获得电源。这样，当该降噪耳机连接到电子设备90以播放音频信号时，就可以通过该电源端16把从电子设备90获得的电源电压传输到噪声消除模块60，供噪声消除模块60作为工作电源使用，而无需为噪声消除模块60单独设置专用的电源(如电池等)。这样，该噪声消除模块60就不需要设置专门的电源，有利于简化硬件结构、降低成本、提高使用的便利性。
另外，耳机插头10的插头本体11上在所述麦克风端12、公用回路端13、右声道端14、左声道端15及电源端16中任何相邻设置的两者之间都设置有绝缘环17。绝缘环17用于将上述各连接端（12/13/14/15/16）相互之间电性隔离，防止出现短路现象。另外，该耳机插头10还可以包括与插头本体11同轴连接的圆盘状底座18，该底座18用绝缘材料制成，可为拿取该耳机插头10提供便利。
与上述耳机插头10相配合使用的电子设备90包括设于其内的音频模块92、电源91和耳机插座20，该耳机插座20用于与上述的降噪耳机的耳机插头10配合使用。该耳机插座20包括座体21，该座体21可以由塑料等绝缘材料制成，并开设有形状与上述耳机插头10对应的插孔27。该座体21内设置有麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25和电源接脚26，其中麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25用于连接到电子设备的音频模块以传输音频信号，电源接脚26则用于连接到电子设备的电源以传输电源电压和电流。所述麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25和电源接脚26都用金属弹片制成，均包括具有弹性的，用于与上述耳机插头10的麦克风端12、公用回路端13、右声道端14、左声道端15和电源端16分别抵持并建立电性连接的抵持部。麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25和电源接脚26的抵持部都设于插孔27内，并依照从插孔27的开口到插孔27的底部的顺序依次排列在插孔27内。
所述耳机插座20除了用于接入上述降噪耳机之外，还可以用于接入带有所述耳机插头10的其他需要电源的电子设备配件，例如便携式扬声器（图未示），或者用于连接无线耳机或无线扬声器的无线音频发射器（图未示）。与将上述降噪耳机连接到电源91的方法相似，所述电源接脚26可用于将便携式扬声器、无线音频发射器或其他需要电源的电子设备配件连接到电源91，从而利用所述电源91向这些电子设备配件供电。
该电子设备90可以是手机、个人电脑、笔记本电脑、平板电脑、音乐播放器、视频播放器、多媒体播放器、便携式游戏机等各种能够播放音频文件的电子设备。该电子设备90包括的电源91是采用电池或是电插头等方式提供电能的电源模块，其中还可以包括电压转换电路、稳压电路和整流电路等辅助性的电路，用于依照常规方式为该电子设备90提供工作电压和电流。所述的音频模块92可以是现有的音频播放电路。
进一步地，所述电子设备90还包括控制装置93，该控制装置93可以是硬件、软件模块或固件，其与电源91电性连接，用于打开或关闭所述电源91对所述耳机插座20的电源输出，从而对应地激活或停用与所述耳机插座20连接的上述降噪耳机、便携式扬声器、无线音频发射器或其他需要电源的电子设备配件。另外，该控制装置93还可用于设置及调节与所述耳机插座20连接的上述降噪耳机、便携式扬声器、无线音频发射器或其他需要电源的电子设备配件的工作参数，例如功率、音量等。
本发明的实施例2：本实施例与实施例1的区别仅在于:如图5所示，所述耳机插座20是将公用回路接脚23、麦克风接脚22、右声道接脚24、左声道接脚25和电源接脚26的抵持部依照从插孔27的开口到插孔27的底部的顺序依次排列在插孔27内。
如图6所示，该耳机插头10中在插头本体11上设置的连接端按照从插头本体11基部到插头本体11顶端的顺序依次为公用回路端13、麦克风端12、右声道端14、左声道端15和电源端16。
所述噪声消除模块60装设于所述底座18中。
由于另一种常用的四段式耳机制式（以下简称第二制式）中，设置在耳机插头的插头本体上的连接端按照从插头本体基部到插头本体顶端的顺序依次为公用回路端、麦克风端、右声道端与左声道端，与本实施例中耳机插座20的公用回路接脚23、麦克风接脚22、右声道接脚24、左声道接脚25的抵持部在插孔27内的设置顺序一致，因此耳机插座20的公用回路接脚23、麦克风接脚22、右声道接脚24、左声道接脚25能够按照现有方式与采用该第二制式的耳机配合使用。这样，该耳机插座20即可兼容上述耳机插头10与现有的采用该第二制式的耳机。
本发明的实施例3：本实施例与实施例1相比，区别仅在于: 所述降噪耳机还包括连接于所述耳机插头10与所述音频播放单元50之间的控制单元30。控制单元30包括用于控制音频播放单元50的开关、音量调节按键或旋钮、音质调节按键或旋钮，以及用于向电子设备输入语音信号的麦克风。
本实施例中音频播放单元50的数量为两个，其中一个音频播放单元50直接与所述耳机插头10电性连接。另一个音频播放单元50则经由所述控制单元30与所述耳机插头10电性连接。在其他实施例中，也可以将两个所述音频播放单元50都经由所述控制单元30与所述耳机插头10电性连接。
所述噪声消除模块60装设于所述控制单元30中。
本发明的实施例4：本实施例与实施例2相比，区别仅在于: 所述降噪耳机还包括连接于所述耳机插头10与所述音频播放单元50之间的控制单元30。控制单元30包括用于控制音频播放单元50的开关、音量调节按键或旋钮、音质调节按键或旋钮，以及用于向电子设备输入语音信号的麦克风。
所述噪声消除模块60连接于所述耳机插头10与所述控制单元30之间，或连接于所述控制单元30与所述音频播放单元50之间。
本发明的实施例5：如图10所示，本实施例与实施例1的区别仅在于：电源接脚26直接设置在PCB电路板19上。
本发明的实施例6：一种用电子设备的电源向便携式扬声器或无线音频发射器供电的方法，在电子设备的耳机插座内或电子设备的PCB电路板上设置电源接脚，在便携式扬声器或无线音频发射器与电子设备的接头上设置电源端，通过电源接脚将便携式扬声器或无线音频发射器接头上的电源端与电子设备的电源相连接，以利用电子设备的电源向便携式扬声器或无线音频发射器供电。
通过控制装置打开或关闭电子设备的电源对电源接脚的电源输出，对应地激活或停用与电源接脚连接的便携式扬声器或无线音频发射器。
所述控制装置是硬件、软件模块或固件；通过控制装置设置及调节与电源接脚连接的便携式扬声器或无线音频发射器的工作参数。
本发明的工作原理：当降噪耳机的耳机插头10插入该插孔27内时，所述麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25和电源接脚26可以分别与麦克风端12、公用回路端13、右声道端14、左声道端15和电源端16的抵持部对应地抵持在一起，从而相互接触并建立对应的电性连接。而且，所述麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25和电源接脚26的抵持部在自身弹性的作用下，均产生回弹趋势而压紧在所述插头本体11上，将耳机插头10稳定地卡持在插孔27内。这样，电子设备的音频模块提供的音频信号即可通过右声道接脚24与左声道接脚25传输到所述耳机插头10，而电源接脚26也可以把电子设备的电源提供的电压和电流传输到所述耳机插头10的电源端16。该降噪耳机的音频播放单元50对经由右声道接脚24与左声道接脚25传来的音频信号进行播放，同时所述噪声消除模块60利用经由电源接脚26和电源端16传输过来的电子设备的电源电压作为能量来源，消除来自外界的噪声，使耳朵听到的外界噪声大大降低，从而能更加清楚地听到耳机插头10接收到的音频信号经由音频播放单元50播放出的声音。这样就可以由电子设备为噪声消除模块60提供工作电源，而无需为噪声消除模块60单独设置专用的电源，有利于简化降噪耳机的硬件结构，降低成本，提高使用便利性。
另外，本发明的耳机插座20也可以兼容现有的绝大部分耳机插头。例如，请参阅图8及图9，其分别为现有的三段式耳机插头和四段式耳机插头插入上述耳机插座20的示意图。由现有的三段式耳机插头和四段式耳机插头的结构很容易得知，现有三段式耳机插头仅包括设置在插头本体上的公用回路端、右声道端、左声道端，也就是相当于将上述降噪耳机的耳机插头10中的麦克风端12与电源端16去除后留下的部分；现有四段式耳机插头仅包括设置在插头本体上的麦克风端、公用回路端、右声道端、左声道端，也就是相当于将上述降噪耳机的耳机插头10中的电源端16去除后留下的部分。因此，现有的三段式耳机插头插入上述耳机插座20的插孔27后，所述公用回路接脚23、右声道接脚24、左声道接脚25的抵持部可以分别与现有的三段式耳机插头的公用回路端、右声道端、左声道端对应地抵持在一起，从而相互接触并建立对应的电性连接，这样上述耳机插座20就可以依照现有方法与现有的三段式耳机插头配合使用。现有的四段式耳机插头插入上述耳机插座20的插孔27后，所述麦克风接脚22、公用回路接脚23、右声道接脚24、左声道接脚25的抵持部可以分别与现有的四段式耳机插头的麦克风端、公用回路端、右声道端、左声道端对应地抵持在一起，从而相互接触并建立对应的电性连接，这样上述耳机插座20就可以依照现有方法与现有的三段式或四段式耳机插头配合使用。
