请参阅图1和图2，本申请实施方式提供一种电路结构100，电路结构100包括电芯11和导电 结构12，电芯11包括正极片110和负极片111，正极片110和负极片111卷绕设置，沿负极片111的卷绕方向，负极片111的外侧端部1110越过正极片110的外侧端部1100的部分为外延段1111；导电结构12包括第一端部120和第二端部121，第一端部120和第二端部121中的至少一端与正极片110或负极片111连接，导电结构12被配置为产生的电磁场与外延段1111产生的电磁场相互削弱。

请参阅图1，本申请实施方式提供一种电池1000，电池1000包括本申请实施方式中所提供的电路结构100。
本申请实施方式中的电池1000因为应用有本申请中提供的电路结构100，电池1000内部电芯11外延段1111部分产生的电磁场能够与导电结构12产生的电磁场相互削弱，达到降低电芯11产生的磁场对外干扰的作用，可以理解的，将电路结构100封装在电池1000中可以有效降低电池的漏磁。
请参阅图11，本申请实施方式还提供一种电子设备10000，电子设备10000包括本申请一些实施方式中所提供的电路结构100。
本申请实施方式的电子设备10000中，由于应用有本申请中的电路结构100，在电子设备10000工作的情况下，导电结构12所提供的磁场能够与电芯11的外延段1111部分产生的磁场相互削弱，例如部分抵消或者完全抵消，从而可以降低外延段1111部分产生的磁场辐射对喇叭等敏感器件的干扰，进而使得电子设备10000的噪声得到有效削弱，甚至消除，提高设备性能和用户使用体验。
随着技术的发展，电子类产品广泛应用在人们生活中，在使用耳机等小型电子产品时，内置的电池电芯为麦克风、喇叭、蓝牙等供电。小型电子产品的内置电池一般为小型充电电池(例如钢壳电池或软包电池)，电池电芯的制作方式一般为卷绕式，虽然相关技术通过一些绕卷方式的改善来降低电池的漏磁，但是漏磁仍难以避免。申请人发现，由于负电极片与正电极片长度不同，或者为了安全负电极片要包裹住正极片的外侧端部，从而负极片的外侧端部越正极片的外侧端部的部分在使用时可能会产生电磁场，造成漏磁。
然而，近年来TWS(True Wireless Stereo，真无线立体声)蓝牙耳机被广泛地使用，TWS蓝牙耳机的体积紧凑，使得电池与喇叭的堆叠距离近，因此，申请人发现上述少量的漏磁在TWS耳机中也可能引起噪声。特别地，随着技术的发展使得大多数蓝牙耳机也带有降噪功能，在使用无线蓝牙耳机的相关功能时，以及在特定使用场景如回连、播放特定格式音频时，噪声更为明显。
经申请人研究发现，引起上述噪声的原因包括：在蓝牙耳机中，由于蓝牙芯片发射蓝牙信号可能会引起电池的电流发生波动，基于前面所述由于电池电芯设计的原因导致漏磁，当电流为变化的情况下，电池漏出的电磁场也是变化的，变化的磁场会对喇叭等敏感器件进行干扰产生噪声。申请人进一步研究发现，在蓝牙芯片进行蓝牙连接，例如蓝牙回连时(例如Page寻呼阶段)，会由于频繁发送ID包和等待接收导致电流波动明显，产生的噪声也更明显。
因此，蓝牙模块引起的电流波动更容易使得与蓝牙模块连接的麦克风、喇叭等声电器件受电池产生电磁场的干扰引发噪声。经过申请人仔细研究发现，针对卷绕电池带来的噪声问题，可以设计有反向线圈，然后通过一定的布置方式使得通电后线圈可以产生与电芯相反的磁场，从而抵消电芯产生的磁场，以减弱对负载的干扰，但受限于空间的影响，以及为了保证对电芯产生的磁场的良好抵消作用，对抵消线圈的设计要求越来越高。
有鉴于此，本申请中提供一种改进后的电路结构100，导电结构12的第一端部120和第二端部121中的至少一端与正极片110或负极片111连接，导电结构12被配置为产生的电磁场与外延段1111产生的电磁场相互削弱，此处的相互削弱可以理解为相互抵消，进一步地，可以是导电结构12产生的电磁场与外延段1111产生的电磁场全部抵消，或者，导电结构12产生的电磁场与外延段1111 产生的电磁场部分抵消，可见，本申请中提供的导电结构12是针对负极片外延段产生的磁场干扰而设计的，抵消的更有针对性，能够有效改善外延段1111产生的干扰磁场对喇叭300等敏感器件的干扰使其产生的噪声等问题。
具体地，本申请中的电子设备10000可以为手机、平板电脑、音频播放器、视频播放器、有线耳机、无线蓝牙耳机例如TWS耳机、音箱等设备，本申请中的电子设备10000的电池1000可以为自带电池。电子设备10000包括的负载200可以包括蓝牙模块21，此外，喇叭300也可以认为是负载200的一部分，也可以理解为负载200以外的部分。电子设备10000应用有本申请中的电路结构100，电路结构100中采用导电结构12针对外延段1111产生的干扰电磁场进行削弱(包括对干扰电磁场的部分抵消或全部抵消)，从而实现抑制负载200引起的电流变化导致电芯11产生干扰磁场对喇叭300等声电器件的影响，进而改善喇叭300发出电流噪声等问题。
下文所提及的电子设备10000以TWS耳机为例进行解释说明。
需要说明的是，在某些实施方式中，本申请中的电子设备1000还包括负载200，电芯11被配置为负载供电。负载可以包括蓝牙模块21，变化电流可以包括电芯11为蓝牙模块21供电的情况下，由于蓝牙模块21收发蓝牙信号引起电芯21产生的波动电流。可以容易理解，电子设备1000中所包括的负载可以与电路结构100中所涉及的负载200为同一负载。
本申请中的电池1000具体可以为卷绕式电池，例如可以为钢壳纽扣电池和微型软包电池等，电芯11可以位于电池1000的内部，电芯11可以为卷绕式电芯11，在电池1000正常工作时，基于电芯的设计，电流流过电芯11可能会产生一个垂直于电池1000顶盖或者电池1000底壳的磁场。
如图2所示，图2的电芯11的卷绕形式和安全要求决定了电芯11的负极片111的外侧端部1110越过正极片110的外侧端部1100。可以理解，电池1000工作时，交变的电流在闭合线圈上会产生磁场，那么对于卷绕式电池1000而言，电池1000电流波动时电芯11正极片110和负极片111所产生的大部分磁场都会相互抵消，而此时，由于负极片111的外侧端部1110越过正极片110的外侧端部1100，越过的部分则没有被抵消，会对外产生磁场辐射。也即是说，外延段1111部分在电芯11通有变化电流时所产生的磁场不会被抵消，而是会对外产生磁场辐射。
因此，电池1000中的电路结构100还设计有导电结构12，导电结构12可以与电芯11串联。需要说明的是，在某些实施方式中，电芯11可以为软包电池或钢壳电池的电芯，和/或，导电结构12可以为导线、FPC或电路板；和/或，导电结构12可以设置在电芯11靠近喇叭200的一侧，或者，导电结构12可以设置在电池1000和喇叭200之间。
可以理解的，导电结构12的第一端部120和第二端部121中的至少一端可以与电芯11的正极片110或负极片111连接，进一步地，导电结构12的第一端部120和第二端部121中的至少一端可以与正极片110的外侧端部1100或负极片111的外侧端部1110连接。导电结构12的实现形式可以是通过柔性电路板、印刷电路板、铜丝绕线等方式。当电芯11通电时，导电结构12中同样存在电流。导电结构12可以为一定弧度的导电线圈，导电结构12的直径、粗细和材料等可以根据需要抵消的磁场辐射强度来综合确定。
导电结构12被配置为产生的电磁场与外延段1111产生的电磁场相互削弱，可以理解为对外延段1111产生的电磁场的部分抵消或全部抵消，从而电子设备10000所包括的负载200(也即电路结构100连接的负载200)，如蓝牙模块21在工作时产生的变化电流通到电芯11后，电芯11的外延段1111部分产生的电磁场可以被导电结构12产生的电磁场所削弱，从而减少了干扰磁场对负载200所连接的喇叭300等器件的影响，进而改善喇叭300发出电流噪声等问题。
请参阅图3-图5，在某些实施方式中，第一端部120的位置与负极片111的外侧端部1110对应，第二端部121的位置与正极片110的外侧端部1100对应，导电结构12的电流被配置为与负极片111的外延段1111的电流方向相反。
如此，导电结构12的设置能够准确对齐外延段1111的位置(当然也允许一定程度的偏离，可根据对噪声控制的实际需要调整)，同时由于将导电结构12的电流被配置为与负极片111的外延段1111的电流方向相反，导电结构12能够产生与外延段1111产生的磁场相反的磁场，从而对外延段1111产生的干扰磁场起到抵消作用，减少磁场对负载200所连接的喇叭300等声电器件的干扰，从 而降低声电器件产生的电流噪声。
可以理解的，第一端部120的位置与负极片111的外侧端部1110对应，第二端部121的位置与正极片110的外侧端部1100对应，上述对应所指代的是第一端部120的投影与负极片111的外侧端部1110的投影在位置上为完全重叠，当然也可以允许有一定误差范围内的错开，可以根据实际设计需求而定。
例如，在一些可行的实施方案中，导电结构12可以通过两个焊盘与正极片110的外侧端部1100或负极片111的外侧端部1110连接，由于焊盘有一定的面积，因此导电结构12的端部(例如第一端部120或第二端部121)可以分别设置在两个焊盘中的任何位置，也可以通过在焊盘不同位置的设置来调整第一端部120到第二端部121的长度或弧度，从而满足抵消外延段1111电磁场的需要。上述在两个焊盘上导电结构12的两个端部(例如第一端部120或第二端部121)与两个焊盘不同的位置建立连接都可认为属于上述“对应”的范畴。
可以理解的，第一端部120的位置与负极片111的外侧端部1110对应，第二端部121的位置与正极片110的外侧端部1100对应，可以是第一端部120的位置设置在靠近负极片111的外侧端部1110的位置，第二端部121的位置可以设置在靠近正极片110的外侧端部1100的位置，这样在第一端部120和第二端部121之间可以形成与外延段1111形状类似的导电结构12，加之导电结构12与外延段1111的电流相反，从而二者产生的电磁场可以相互抵消(包括部分抵消或者全部抵消)。
可以理解的，第一端部120的位置与负极片111的外侧端部1110对应，第二端部121的位置与正极片110的外侧端部1100对应，还可以是第一端部120的位置设置在负极片111的外侧端部1110的位置(例如二者在不同平面上重叠)，第二端部121的位置可以设置于正极片110的外侧端部1100对应的位置(例如电芯11的绕线形成圆的圆心和正极片110的外侧端部1100连线于负极片111的交点处，或者可以理解为，外延段1111的起始位置与第二端部121的位置对应，外延段1111的终止位置，也即负极片111的外侧端部1110所在位置，与第一端部120对应，从而可以将导电结构12设置为在外延段1111所在平面上的投影与外延段1111完全重叠或部分重叠，当完全重叠时，导电结构12产生的磁场和外延段1111产生的磁场的抵消效果可能更明显。
可以理解的，当电池1000正常工作时，流经电芯11的电流也将流过导电结构12，而导电结构12的电流被配置为与负极片111的外延段1111的电流方向相反，在此情况下，导电结构12会产生一个与电芯11所产生的磁场方向相反的磁场，这样导电结构12所产生的磁场便可以抵消(部分抵消或者完全抵消)外延段1111部分对外产生的磁场辐射。
特别地，图2也示出了，电芯11的负极片111的内侧端部也会超出正极片110的内侧端部，但是由于实际情况中电芯11的内圈，即内侧的弧度非常小，超出部分可以忽略不计；并且，电芯11内圈所流过的电流也较小，电芯11的电流由内圈到外圈逐渐增大，对于电池1000而言，电芯11内圈的磁场强度较弱，因此在设计导电结构12时，可以仅考虑消除外延段1111部分对外的辐射磁场来设计导电结构12的具体结构。
请参阅图3，在某些实施方式中，第一端部120被配置为连接负极片111的外侧端部1110，和/或，第二端部120被配置为连接正极片110的外侧端部1100。
可以理解的，第一端部120被配置为连接负极片111的外侧端部1110，第二端部120被配置为连接正极片110的外侧端部1100第一端部120；或者，第一端部120被配置为连接负极片111的外侧端部1110；或者，第二端部120被配置为连接正极片110的外侧端部1100。
其中，第一端部120连接负极片111的外侧端部1110，可以是通过焊盘、镍片等连接方式连通；同样，第二端部121连接正极片110的外侧端部1100，可以是通过焊盘、镍片等连接方式连通。一般来说，正极片110的外侧端部1100与正极耳连接和负极片111的外侧端部1110与负极耳连接，此外，正极耳可以直接与正极焊盘连接或通过镍片与正极焊盘连接，同样的，负极耳可以直接与负极焊盘连接或通过镍片与负极焊盘连接。
请参阅图2与图3，在某些实施方式中，在第一端部120被配置为连接负极片111的外侧端部1110的情况下，第二端部121的位置设于正极片110的外侧端部1100处；或者，在第二端部121被配置为连接正极片110的外侧端部1100的情况下，第一端部120的位置设于负极片111的外侧端 部1110处。
可以理解的，在第一端部120被配置为连接(可以直接连接也可以间接连接，例如通过极耳、镍片、焊盘等至少一种间接连接)负极片111的外侧端部1110的情况下，第二端部121的位置设于正极片110的外侧端部1100处，即第二端部121的位置与正极片110的外侧端部1100对应；在第二端部121被配置为连接正极片110的外侧端部1100的情况下，第一端部120的位置设于负极片111的外侧端部1110处，即第一端部120的位置与负极片111的外侧端部1110对应。
可以理解的，由于正极片110的外侧端部1100与外延段1111靠近正极片110的外侧端部1100的一端比较接近，因此第二端部121的位置设于正极片110的外侧端部1100处，也可以包括第二端部121的位置设于外延段1111靠近正极片110的外侧端部1100的一端。
可以理解的，导电结构12与电极片(正极片110和负极片111)可以不在一个平面，因此“对应”或者“处”也可以理解为投影上的重叠或部分重叠。
这样，导电结构12的设置能够对应外延段1111的位置；同时，又由于将导电结构12的电流被配置为与负极片111的外延段1111的电流方向相反，导电结构12能够产生与外延段1111产生的磁场相反的磁场，从而对外延段1111产生的干扰磁场起到抵消作用，避免干扰磁场影响负载所连接的喇叭300等声电器件使声电器件产生电流噪声。
另外，如图2所示，在电芯11内部电流由负极片111流向正极片110，从而电芯11的负极片111的电流方向为逆时针方向，正极片110的电流方向为顺时针方向，从而正极片110和负极片111产生的部分磁场可以相互抵消，但外延段1111产生的磁场无法被电池1000本身的设计抵消，因此需要通过本申请设计的导电结构12进一步抵消外延段1111产生的电磁场(包括部分抵消或全部抵消)。那么如图3所示，导电结构12上流过的电流方向需要为顺时针方向，即，在第一端部120被配置为连接负极片111的外侧端部1110的情况下，第二端部121的位置设于正极片110的外侧端部1100处；或者如图4所示，在第二端部121被配置为连接正极片110的外侧端部1100的情况下，第一端部120的位置设于负极片111的外侧端部1110处，导电结构12上流过的电流方向仍为顺时针方向，需要另外说明的是，图4中为区别导电结构12与电芯11，将导电结构12以虚线形式表示，并不代表实际结构。
这样，如图2所示，未设置导电结构12前电池1000出线的正极与负极位于不同侧，在经过导电结构12的绕线后，如图3所示，电芯11与导电结构12结合作为一个模组的情况下，电池1000负极的出线位置相当于延长到了第二端部121，从而与电池1000的正极位于同一侧，当然如果将导电机构12和电芯11封装在电池1000内部，则通过该设计可使得电池1000最终出线的正极与负极位于同一侧，因此，都可以方便后续引出导线与其他元件相接。当然也可以如图4所示，在电芯11与导电结构12结合作为一个模组的情况下，电池1000正极的出线位置相当于延长到了第一端部120，从而与电池1000的负极位于同一侧，当然如果将导电机构12和电芯11封装在电池1000内部，则通过该设计可使得电池1000最终出线的正极与负极位于同一侧，因此，都可以方便后续引出导线与其他元件相接。
在某些实施方式中，电芯11被配置为给负载200供电，第一端部120被配置为连接负极片111的外侧端部1110，正极片110的外侧端部1100被配置为连接负载200的电流输入端，第二端部121被配置为连接负载200的电流输出端。
可以理解的，电子设备10000可以为耳机，例如可以为无线蓝牙耳机，那么负载200可以包括蓝牙模块21，电芯11可以被配置为蓝牙模块21供电，在第一端部120被配置为连接负极片111的外侧端部1110的情况下，正极片110的外侧端部1100被配置为连接负载200的电流输入端，第二端部121被配置为连接负载200的电流输出端。在电芯11与导电结构12形成一个整体时，相当于电池1000的整体出线位于同一侧。
在某些实施方式中，电芯11被配置为给负载200供电，第二端部121被配置为连接正极片110的外侧端部1110，第一端部120被配置为连接负载200的电流输入端，负极片111的外侧端部1110被配置为连接负载200的输出端。
可以理解的，电子设备10000可以为耳机，例如可以为无线蓝牙耳机，那么负载200可以包括 蓝牙模块21，电芯11可以被配置为蓝牙模块21供电，在第二端部121被配置为连接正极片110的外侧端部1100的情况下，第一端部120被配置为连接负载200的电流输入端，负极片111的外侧端部1110被配置为连接负载200的输出端。
请参阅图5与图6，在某些实施方式中，在第一端部120被配置为连接负极片111的外侧端部1110，第二端部121被配置为连接正极片110的外侧端部1100的情况下，导电结构12还包括第三端部122和第四端部123，第一端部120至第三端部122构成导电结构12的第一部分124，第二端部121至第四端部123构成导电结构12的第二部分125，第三端部122与第四端部123间隔设置。
可以理解的，间隔设置可以间隔一小段距离，避免导致导电结构12的整体长度影响磁场的抵消效果，此外第三端部122和第四端部123不直接连接，例如通过负载形成环路。
请参阅图5与图6，在某些实施方式中，第三端部122和第四端部123能够设置于导电结构12的任意位置；和/或，第一部分124的长度和第二部分125的长度相同或不同。
如此，可以实现导电结构12的负极走线与正极走线结合，如果导电结构12和电芯11封装在电池内部，则可以选择在导电结构12的任意位置引出电池1000的正负极接线；如果导电结构12位于电池1000外部，则相当于可以在导电结构12的任意位置引出电池1000的正负极接线。
可以理解的，如图2所示，在电芯11内部电流由负极片111流向正极片110，从而电芯11的负极片111的电流方向为逆时针方向，正极片110的电流方向为顺时针方向，从而正极片110和负极片111产生的部分磁场可以相互抵消，但外延段1111产生的磁场无法被电池1000本身的设计抵消，因此需要通过本申请设计的导电结构12进一步抵消外延段1111产生的电磁场(包括部分抵消或全部抵消)。
那么如图5和图6所示，为了能够与外延段1111的磁场形成抵消作用，导电结构12上流过的电流方向需要为顺时针方向，进一步的为了方便与负载连接，导电结构12可以包括有第一部分124和第二部分125。其中，第一部分124包括第一端部120至第三端部122，第一端部120可以被配置为电连接负极片111的外侧端部1110，从而第一部分124与电芯11的负极片111电连接，第一部分124的走线由对应电芯11的负极片111的外侧端部1111的位置开始到第三端部122结束；第二部分125可以包括第二端部121至第四端部123，第二端部121可以电连接正极片110的外侧端部1100，从而第二部分125与电芯11的正极片110电连接，第二部分125的走线由对应电芯11的正极片110的外侧端部1100的位置开始到第四端部123结束。
进一步地，若导电结构12和电芯11封装在电池1000中，则第一部分124与第二部分125上还形成有电池1000最终出线的正负电极，即第一部分124和第二部分125的走线停止位置第三端部122和第四端部123分别为电池1000最终的负极接线位置和正极接线位置；如果导电结构12设置在电池1000外部，则第三端部122和第四端部123相当于延长了电池1000的负极接线位置和正极接线位置。
如图5和图6所示，电芯11串联有第一部分124和第二部分125的情况下，第三端部122和第四端部123能够位于导电结构12的任意位置，或者说，第一部分124的长度与第二部分125的长度相同或者不同。如图5中，第一部分124的长度大于第二部分125的长度，图6中，第一部分124的长度小于第二部分125的长度，此时第一部分124和第二部分125上流过的电流方向均为顺时针方向。
可以理解的，无论第三端部122和第四端部124位于导电结构12的哪个位置，导电结构12所起的作用在电池1000中是相同的，即导电结构12所产生的磁场抵消效果一致。上述实施例或实施方式中(包括但不限于图3-图6的任一方案)，无论导电结构12采用哪种与电池的连接方式及与负载连接的出线方式，其形状(例如长度或弧度)的设置要与外延段1111对应，从而使得导电结构12与外延段1111产生的电磁场可以相互削弱(包括部分抵消或全部抵消的情况)。且导电结构12的形状设计(例如长度或弧度)可以根据需要抵消磁场的程度进行调整。
请参阅图7-图10，在某些实施方式中，电芯11被配置为给负载200供电，第三端部122被配置为连接负载200的电流输出端，第四端部123被配置为连接负载200的电流输入端。
可以理解的，如上文所提及的，在一些实施例中，第一部分124与第二部分125上还形成有电 池1000最终出线的正负电极，即第一部分124和第二部分125的走线停止位置第三端部122和第四端部123分别为电池1000最终的负极接线位置和正极接线位置。在电芯11为负载200，如蓝牙模块21供电的情况下，第三端部122被配置为连接负载200的电流输出端，第四端部123被配置为连接负载200的电流输入端，电流由第一端部电流由第四端部123流入负载200，然后由第三端部122流出负载200。需要说明的是，上述连接可以是直接连接也可以是间接连接，例如通过连接结构进行连接。可以理解的，本申请实施例中第一端部120和第二端部121是导电结构12上的指定点，这种端部可能与其连接的部分一体成型，例如第一端部120和第二端部121分别与其各自的连接机构一体成型，例如为一根导线。当然也可以是能够与连接结构进行拆分的形式，在此不做限制。
请参阅图7-图10，在某些实施方式中，第三端部122被配置为通过第一连接结构126与负载200的电流输出端连接，第四端部124配被配置为通过第二连接结构127与负载200的电流输入端连接，第一连接结构126与第二连接结构127重叠走线。如此，将第一连接结构126与第二连接结构127重叠走线可以使得第一连接结构126产生的电磁场和第二连接结构127产生的电磁场相互抵消，从而降低或避免对负载200或负载200连接的喇叭300等其他模块产生干扰磁场，引起电流声等问题。
具体地，在电子设备10000为耳机的情况下，图7与图8为分别为左耳机、右耳机在一种实施方式下的内部走线示意图，图9与图10分别为左耳机、右耳机在另一种实施方式下的内部走线示意图。在图7与图8中，第一部分124与第二部分125的长度基本相同，在图9与图10中，第一部分124的走线长度大于第二部分125的走线长度。
在图7-图10示出的两种走线方案中，第一端部120被配置为连接负极片111的外侧端部1110，第二端部121被配置为连接正极片110的外侧端部1100的情况下，那么导电结构12还包括第三端部122和第四端部123，第三端部122与第四端部123与负载200连接的情况下，内部走线需要经过与负载200连接的喇叭300所覆盖的地方。
此时为了避免产生新的干扰磁场，在第三端部122被配置为通过第一连接结构126与负载200的电流输出端连接，第四端部124配被配置为通过第二连接结构127与负载200的电流输入端连接的情况下，第一连接结构126与第二连接结构127需要重叠走线，来对第一连接结构126和第二连接结构127各自产生的电磁场进行相互抵消。特别地，图7-图10中所示的连接正极耳112(如图2所示)的正极焊盘114，以及连接负极耳113(如图2所示)的负极焊盘115可以用于连接导电结构12或者其他外部器件。
请参阅图3-图10，在某些实施方式中，导电结构12的形状可以与外延段1111的形状对应。如此，通过将外延段1111与导流结构12的形状对应，使得电池1000工作时，导流结构12所产生的磁场与外延段1111所产生的磁场方向相反以相互抵消(部分抵消或全部抵消)，从而有效抑制外延段1111产生的干扰磁场。
具体地，如图2所示的电芯11卷绕形式和安全要求决定了电芯11的负极片111的外侧端部1110越过正极片110的外侧端部1100，也即是负极片111所包括的外延段1111。可以理解，电池1000工作时交变的电流在闭合线圈上会产生磁场，那么对于卷绕式电池1000而言，电池1000电流波动时电芯11正极片110和负极片111所产生的大部分磁场都会相互抵消，而此时，由于负极片111的外延段1111的存在，外延段1111部分对应所产生的磁场无法被抵消，外延段1111处会对外产生磁场辐射。
为了抵消外延段1111对外产生的磁场辐射设置有导电结构12，为了保证导电结构12所产生的磁场尽可能的与外延段1111对外辐射的磁场相互抵消，外延段1111与导电结构12的形状可以对应，需要说明的是，此处的对应可以是将导电结构12在负极片111卷绕平面的投影与外延段12部分重叠或全部重叠。
请参阅图3-图10，在某些实施方式中，导电结构12可以被配置为不超过一圈的弧状结构。具体地，由于电芯11为卷绕形式，负极片111的外延段1111可以为弧状结构；由于为了使导电结构12充分抵消外延段1111对外辐射的磁场，导电结构12可以与外延段1111形状对应，因此导电结构12也可以呈弧状结构。特别地，为了保证导电结构12的走线简单，避免多圈绕线导致的无法布线、布 线困难，以及绕线圈数过多导致电池走线过长带来导通阻抗变大等问题，以及考虑到外延段1111的长度、形状，导电结构12可以被配置为不超过一圈的弧状结构。
进一步地，请参阅图2与图3，在某些实施方式中，导电结构12的弧度与外延段1111相同或相近，或者，导电结构12的长度与外延段1111的长度相同或相近。具体地，外延段1111与导流结构12的形状对应，可以是导电结构12的弧度与外延段1111相同或相近，或者，导电结构12的长度与外延段1111的长度相同或相近。这样，使得电池1000工作时，导流结构12所产生的磁场与外延段1111所产生的磁场方向相反，可以相互抵消，从而有效抑制外延段1111产生的干扰磁场。
在某些实施方式中，导电结构12的弧度或长度被配置为根据喇叭300发出的电流声确定，其中，电芯11为负载200供电，负载200与喇叭300连接。
可以理解的，负载200可以包括蓝牙模块21，负载200可以与喇叭300连接，负载200在工作时所引起的变化电流会导致喇叭300受到影响产生电流噪声，因此导电结构12为了消除喇叭300产生的电流噪声，需要抵消变化电流引起的干扰磁场，因此为了抵消效果更好，导电结构12的弧度或长度被配置为根据喇叭300发出的电流声确定。例如在出厂前通过检测喇叭产生电流声的情况来调整导电结构的长度、弧度、位置等参数，当调整到某个参数使得电流声满足设计要求时，例如超出人耳听到的范围或者比较微小大部分人听不到的情况，则确定该参数下的导电结构12为满足需要的导电结构。
特别地，在一些实施方式中，还可以根据外延段1111所产生的辐射磁场的强度，调整导电结构12的弧度，例如，若是外延段1111对外辐射强度过大，导电结构12的弧度可以调整为较大的弧度，若是外延段1111对外辐射强度较小，导电结构12的弧度可以对应调整为小弧度。此时，调整弧度可以是第一端部120与第二端部121保持电连接负极片111的外侧端部1110以及位于正极片110的外侧端部1100不变，调整由第一端部120向第二端部121延伸的导电结构12的弧度。
请参阅图2-图6，在某些实施方式中，电芯11可以包括正极耳112和负极耳113(如图2所示)，正极片110的外侧端部1100被配置为通过正极耳112和第二端部121连接；和/或，负极片111的外侧端部1110被配置为通过负极耳113与第一端部120连接。
请参阅图2、图7-图10，进一步地，在某些实施方式中，正极耳112可以通过正极焊盘114与第二端部121连接；和/或，负极耳113可以通过负极焊盘115与第一端部120连接。
可以理解的，正极片110的外侧端部1100被配置为通过正极耳112和第二端部121连接以及负极片111的外侧端部1110被配置为通过负极耳113与第一端部120连接，或者正极片110的外侧端部1100被配置为通过正极耳112和第二端部121连接，或者负极片111的外侧端部1110被配置为通过负极耳113与第一端部120连接等情况下，正极耳112可以通过正极焊盘114与第二端部121连接；和/或，负极耳113可以通过负极焊盘115与第一端部120连接。其中，如前面所描述的，由于焊盘具有一定的面积，为了调整导体结构12的参数(例如长度、弧度、位置等)，第二端部121可以在正极焊盘114上调整连接位置，第一端部120也可以在负极焊盘115上调整连接位置。
此时，正极焊盘114可以通过镍片与正极耳112连接，负极焊盘115也可以通过镍片和负极耳113连接，当然也可以不通过镍片直接将正极焊盘114、负极焊盘115分别与正极耳112和负极耳113连接，又或者，第一端部120和/或第二端部121可以不连接负极焊盘115和/或正极焊盘114，直接与负极耳113和/或正极耳112连接在一起。
可以理解的，无论是正极焊盘114还是负极焊盘115，都有一定的面积，从而可以在焊盘上选取更合适的导电结构12的连接位置，从而使得导电结构12与正极片110或者负极片111的外侧端部1110位置有一定的偏差，但也仍属于对应的范围。
在某些实施方式中，电芯11与导电结构12封装在电池1000内部；或者，电芯11封装在电池1000内部，导电结构12设置在电池1000外部。
请参阅图1，在某些实施方式中，导电结构12可以设置在电芯11靠近喇叭300的一侧；或者，导电结构12可以设置在电池1000和喇叭300之间。
可以理解的，导电结构12设置在电芯11靠近喇叭300的一侧，可以包括电芯11和导电结构12封装在电池内部的情况；导电结构12设置在电池1000和喇叭300之间，可以包括导电结构12 设置在电池1000外部的情况。
上述，通过将导电结构12靠近喇叭300设置，使得导电结构12起到的抵消干扰磁场的作用更好，可以降低或消除干扰磁场引起喇叭300产生的噪声。
具体地，在一个实施例中，TWS耳机一类电子设备10000的内置电池的电芯11具有更高的高度，这使得如果将导电结构12设置在电芯11远离喇叭300的一侧上，导电结构12由于距离喇叭300较远，在电子设备10000工作过程中导电结构12所产生的磁场抵消作用会减弱，容易造成磁场抵消不足，从而影响对喇叭300产生的噪声的降噪效果，或者为了满足控制噪声的效果，需要加大的线圈，导致结构堆叠困难，也增加耳机的重量和成本等。
因此，本申请中将导电结构12设置在电芯11和负载200之间，从而使得导电结构12距离喇叭300的距离较近，避免导电结构12产生的反向磁场出现抵消不足的问题，此外，导电结构12可以更小巧，磁场抵消效果较好。
请参阅图1，在某些实施方式中，导电结构12所在的平面与负极片111卷绕形成的平面平行或基本平行。如此，导电结构12在保证对外延段1111产生的磁场的削弱效果的同时可以控制堆叠空间。
可以理解的，在一个实施例中，电芯11为卷绕式电芯11，导电结构12可以为弧线状。将导电结构12所在的平面与负极片111卷绕形成的平面平行或基本平行，例如设置在远离喇叭300一侧的电芯11的顶面并且平行于电芯11的顶面设置，或者设置在靠近喇叭300一侧的电芯11的底面并平行于电芯11的底面，这样，可以更好地布置导电结构12，减小导电结构12占用的空间，减小设备的整体体积，并且还能更好地对应抵消电芯11的负极片111的外侧端部1110越过正极片110的外侧端部1100的部分产生的干扰磁场，从而电子设备10000的内部避免布置复杂的防磁场干扰结构，进而降低了电子设备10000的成本。
可以理解的，当导电结构12封装在电芯11内部时，可以嵌入到电芯11中，类似于抵消电芯11的负极片111长度或补齐电芯11的正极片110长度的方式，设置导电结构12。
在某些实施方式中，导电结构12被配置为在通变化电流时产生第一电磁场，电芯11被配置为在通变化电流时产生第二电磁场，第一电磁场与第二电磁场相互削弱，第二电磁场包括在通变化电流时外延段1111产生的电磁场。
需要说明的是，相互削弱包括相互抵消，其中抵消可以是部分抵消，也可以是全部抵消。
进一步地，在某些实施方式中，电芯11为负载200供电，负载200可以包括蓝牙模块21，变化电流可以包括电芯11为蓝牙模块21供电的情况下，蓝牙模块21收发蓝牙信号引起的电芯11产生的波动电流。
具体地，导电结构12与电芯11串联，导电结构12的电流可以被配置为与负极片111的外延段1111的电流方向相反。蓝牙模块21可以与喇叭300、麦克风等连接，可以理解，在某些实施方式中，电子设备10000可以包括耳机，耳机可以为蓝牙耳机,例如TWS蓝牙耳机，在蓝牙模块21工作时，电芯11可以为蓝牙模块21供电，此时蓝牙模块21会进行蓝牙信号的收发从而引起电芯11产生电流波动，即波动电流，也即形成变化电流。
因此，导电结构12在被通变化电流时产生第一磁场，电芯11被通变化电流时产生第二电磁场，也即是，自负极片111上与正极片110的外侧端部1100对应位置延伸至负极片111的外侧端部1110形成的外延段1111通变化电流时产生的电磁场，此时，第一电磁场与第二电磁场的方向相反，第一电磁场与第二电磁场相互削弱。
在某些实施方式中，由于蓝牙模块21收发蓝牙信号引起的波动电流可以包括：在蓝牙回连过程中引起的电芯11产生的波动电流。如此，导电结构12的设置可以避免在使用蓝牙模块21回连外部设备时引起的电池1000的电流波动导致电子设备10000产生电流噪声。
请参阅图11，具体地，电子设备10000可以包括蓝牙模块21，电子设备10000可以用于通过蓝牙模块21与外部设备无线通信连接。如此，可以实现电子设备10000的无线连接，为用户带来更方便的使用电子设备10000的体验，
具体地，外部设备可以是手机、平板电脑、音频播放器等设备。在一个实施中，电子设备10000可以为TWS耳机，电子设备10000通过蓝牙模块21与外部设备无线通信连接，从而使用户使用便 携、摒弃耳机线材缠绕的烦恼，增强用户体验。
在一个实施例中，电子设备10000可以为耳机，进一步地可以为无线蓝牙耳机，外部设备可以为手机，在电子设备10000的使用过程中，电子设备10000在与外部设备配对建立连接后，保存有连接记录，当与外部设备断开连接后，重新连接时，例如蓝牙TWS耳机的开盖自动连接到上一个连接过的设备或超距重连，可以理解为回连。进一步地，电子设备10000在回连模式时会产生800Hz，3.2KHz频率的电流波动，电池1000就会产生800Hz，3.2KHz频率的交变磁场。然而，在开启降噪模式使得蓝牙模块21的编码译码器需要打开的情况下，由于如喇叭300、麦克风等声电器件连接到蓝牙模块21，喇叭300与蓝牙模块21构成闭合的回路，喇叭300在干扰磁场(例如第一磁场)的作用下会振动发出噪声，噪声的频率即为800Hz，3.2KHz以及它们的倍频。
此时，为了避免电流噪声的产生，电子设备10000的电池1000设置有导电结构12，导电结构12可以和负极片111形成感应磁场相互抵消，即电芯11产生第一感应磁场，导电结构12产生第二感应磁场，第一感应磁场与第二感应磁场相互削弱，从而抵消(部分抵消或完全抵消)电芯11的负极的外延段1111所产生的干扰磁场，避免干扰磁场影响喇叭300使电子设备10000产生电流噪声。
在某些实施方式中，蓝牙模块21可以包括蓝牙编解码器，变化电流可以包括电芯11为蓝牙模块21供电时，收发LHDC格式的文件引起的波动电流。如此，导电结构12的设置可以避免电子设备10000通过收发LHDC格式的文件时，电子设备10000产生电流噪声。
那么为了避免电流噪声的产生，电子设备10000的电池1000内或电池1000外部设置有导电结构12，导电结构12可以和负极片111形成感应磁场相互抵消，即电芯11产生第一感应磁场，导电结构12产生第二感应磁场，从而抵消电芯11的负极的外延段1111所产生的干扰磁场，降低干扰磁场影响喇叭300使电子设备10000在收发LHDC格式的文件的情况下产生电流噪声。
在某些实施方式中，第二电磁场干扰喇叭300引起噪声，变化电流、第二电磁场和噪声的频率相同，频率至少包括以下一种：800Hz、1.6KHz、3.2KHz及其中任一个的倍频。
