具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
以下，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。
在本申请的描述中，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“竖向”、“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“设置”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
无线耳机可以与手机、笔记本电脑、手表等电子设备配合使用，处理电子设备的媒体、通话等音频业务，以及其他一些数据业务。例如，该音频业务可以包括为用户播放音乐、录音、视频文件中的声音、游戏中的背景音乐、来电提示音等媒体业务；还可以包括在电话、微信语音消息、音频通话、视频通话、游戏、语音助手等通话业务场景下，为用户播放对端的语音数据，或采集用户的语音数据发送给对端等。
在现有技术中，无线耳机可以包括一对配合使用的耳机本体，每个耳机本体可以包括两个电连接器。示例性的，如图1所示，无线耳机01包括两个耳机本体10，该耳机本体10可以包括杆体11，和与杆体11顶部相连的耳塞。杆体11底端设置有两个电连接器111。耳机本体11的外壳上的两个电连接器111，暴露于耳机本体10之外，且分别通过连接线与耳机本体10中电源模块的两个电极(即正极和负极)直连，即电连接器111与电源模块的电极之间不经过其他器件。并且，每个耳机本体中还可以包括电池。当耳机本体上的两个电连接器与充电盒上对应设置的两个电连接器电连接时，可以通过充电盒为耳机本体中的电池充电。
日常的生产和生活中普遍存在静电放电ESD现象。例如，耳机本体与其他物体摩擦，或者用户用手触摸耳机本体等，均可能发生ESD现象。由于雷电、电气设备启停和故障等原因还可能发生浪涌现象。例如，耳机本体在充电时接通电路的瞬间可能发生浪涌现象。干扰信号，例如ESD和浪涌等产生的高频、高压干扰信号以及其他干扰信号，可以通过暴露于耳机本体外部的电连接器，导入耳机本体内部。其中，高频、高压干扰信号是指频率高于预设频率值，或者电压高于预设电压值的干扰电信号。以下实施例主要以从电连接器导入耳机本体内部的干扰信号，包括高频、高压干扰信号为例进行说明。
在现有技术中，由于耳机本体上设置的两个电连接器通过连接线与电源模块的正极和负极直连，因而该电连接器从耳机本体外部导入的ESD、浪涌等高频、高压干扰信号，可能会 击穿耳机本体的电路系统中的器件，或对电路系统造成其他的干扰和影响，降低耳机系统的稳定性。
随着无线耳机的体积越来越小，ESD、浪涌等对无线耳机的干扰问题也越来越严重。无线耳机暴露在外面的电连接器，更容易将ESD、浪涌等高频、高压干扰信号导入无线耳机内部，从而可能干扰或损坏无线耳机内部的器件和电路。
参见图2中的(a)和(b)，本申请实施例提供了一种无线耳机21，该无线耳机21可以包括配合用户的左、右耳使用的一对耳机本体211。该耳机本体具体可以为耳塞式，挂耳式或入耳式耳机等。例如，该无线耳机可以是真无线立体声(true wireless stereo，TWS)耳机。
具体的，每个耳机本体可以包括两个电连接器(或称触点)。每个耳机本体上的至少一个电连接器，通过抗干扰器件(或称串联抗干扰器件后)与耳机本体中电源模块的电极(即正极或负极)电连接。该抗干扰器件可以用于抑制耳机本体的电连接器从外部导入的干扰信号，例如ESD、浪涌等产生的高频、高压干扰信号，减小这些干扰信号对耳机本体的电路系统的干扰和影响，提高无线耳机系统的稳定性。其中，抗干扰器件抑制高频、高压干扰信号可以包括衰减、吸收或过滤高频、高压干扰信号，以使得高频、高压干扰信号失去高频、高压特性，从而减小对耳机电路中的器件造成的影响。
并且，耳机本体内还可以包括电池。参见图2，当耳机本体211上的两个电连接器，与用于收纳无线耳机21的充电盒22上对应设置的两个电连接器电连接时，可以通过耳机盒22为耳机本体211中的电池进行充电。

在图5A所示的方案中，在耳机本体进行充电时，从耳机电连接器导入的正常充电信号以及高频、高压干扰信号都可以经过抗干扰器件后，再接入电源模块；在不进行充电时，从耳机电连接器导入的高频、高压干扰信号可以经过抗干扰器件后，再接入电源模块。
这样，从耳机电连接器导入的高频、高压干扰信号可以被抗干扰器件抑制后，再接入电 源模块，从而可以减小高频、高压干扰信号对耳机本体内电路系统的干扰和影响，提高耳机系统的稳定性。
其中，耳机电连接器通过抗干扰器件与耳机本体电源模块的电极电连接是指，耳机电连接器先通过连接线与抗干扰器件电连接，而后再通过抗干扰器件与耳机本体电源模块的电极电连接。即，耳机电连接器先通过抗干扰器件后，才连接到耳机本体中的其他电路。
在一些实施例中，耳机电连接器输入的电信号通过电源管理单元进行电压调节等处理后，再为耳机本体中的电池进行充电。因而，第一耳机电连接器或第二耳机电连接器中的至少一个，可以通过抗干扰器件与电源管理单元的电极相连。电池中的电量可以通过电源管理单元的升压/降压等处理后，为系统其他电路供电。该种情况对应的电路原理图可以参见图5B。在不进行充电时，从耳机电连接器导入的高频、高压干扰信号可以经过抗干扰器件后，再进入电源管理单元；在充电时，从耳机电连接器导入的正常充电信号以及高频、高压干扰信号可以经过抗干扰器件后，再进入电源管理单元，并通过电源管理单元的处理后，再输入电池进行充电。
这样，从耳机电连接器导入的高频、高压干扰信号可以被抗干扰器件抑制后再进入电源管理单元及其他电路，因而可以减小ESD、浪涌等高频、高压干扰信号对耳机本体内电路系统的干扰和影响，可以提高无线耳机系统的稳定性。
具体的，当第一耳机电连接器与电源管理单元的正极通过抗干扰器件电连接时，第二耳机电连接器可以与电源管理单元的负极直连，或者与电源管理单元的负极通过抗干扰器件电连接。当第一耳机电连接器与电源管理单元的负极通过抗干扰器件电连接时，第二耳机电连接器可以与电源管理单元的正极直连，或者与电源管理单元的正极通过抗干扰器件电连接。
在如图1所示的现有方案中，两个耳机电连接器均设置于耳机本体的杆体底端。示例性的，现有方案中杆体底端两个电连接器的安装示意图可以参见图5C中的(a)，两个电连接器501安装在杆体底端的电路板502上。杆体底端电路板的电路原理图可以参见图5C中的(b)，杆体底端的电路板502上包括两个用于焊接耳机电连接器的焊盘503，麦克风收音电路中器件的设置区域504和收音孔505等。对应于电路板502上的收音孔505的位置，耳机本体的杆体底端也设置有收音孔506，以使得用户的话音信号可以通过收音孔506和收音孔505传送到麦克风。并且，如图5C中的(a)所示，收音孔506外部还设置有防尘网507，用于防止灰尘和杂质通过收音孔506进入耳机本体内部。
如图5C所示，由于杆体底部的空间有限，因而杆体底部电路板上的空间也有限，考虑到可能存在器件的安装误差，电路板上不同器件之间需要预留一定的距离；并且，考虑到信号之间的相互耦合等影响，电路板上不同信号之间也要间隔一定的距离，因而杆体底部耳机电连接器附近的空间较为紧张。若为了降低ESD、浪涌等信号的影响，在耳机电连接器和电源模块之间增加抗干扰器件，则将使得杆体底部的空间更为紧张，从而增大了无线耳机电路设计的难度。
在本申请的一些实施例中，两个耳机电连接器在耳机本体上分散设置，即两个耳机电连接器并不是都设置在杆体的底端。其中，分散设置是指，耳机本体上的两个电连接器之间的距离大于或者等于预设值。这样，分散设置的每个耳机电连接器，在耳机本体内部都可以有较为充分的空间来设置抗干扰器件，从而使得电路设计较为简单。示例性的，图4所示的耳机本体可以包括在耳机外壳上分散设置，且与内部部件相连的第一耳机电连接器43和第二耳机电连接器44。
图6A示出了耳机本体600的一种结构示意图。该耳机本体600可以包括杆体601，以及 与杆体601顶部相连的耳塞602。杆体601和耳塞602内部可以包括电路板和电池等内部部件。电路板上可以包括处理器、存储器、充电电路等多种组件，以实现上述无线通信模块303、音频模块304和电源模块305等各项功能。例如，电池可以设置在杆体601的腔体内部。音频模块304中的扬声器组件可以设置于耳塞602的腔体内部。当用户戴上耳塞时，可以听到扬声器组件发出的声音信号，从而为用户实现播放音乐、接/打电话等功能。第一耳机电连接器设置在杆体601的底部，第二耳机电连接器设置在耳机本体600除杆体601底端以外的其他位置，以与第一耳机电连接器分散设置。
其中，当仅有一个第一耳机电连接器设置在杆体底端时，整个杆体底部的空间都可以用于设置该第一耳机电连接器，因而第一耳机电连接器的面积较大，充电时与盒电连接器的接触面积较大，接触性较好，接触电阻较小，充电效率也较高。
此外，当杆体底端仅设置一个耳机电连接器时，杆体底端可以设计得更为美观。当另一个耳机电连接器设置在耳塞外侧壁上与杆体向底端延伸的一侧相对的位置时，该耳机电连接器不易被用户看到，可能会被杆体或耳塞遮挡，因而使得耳机本体看起来更为简洁美观。
在一些实施例中，第一耳机电连接器设置在杆体601的底端，第二耳机电连接器设置在耳塞602外侧壁605上的任意位置，以与第一耳机电连接器分散设置。
例如，如图6A所示，第一耳机电连接器603设置在杆体601的底端，或者说第一耳机电连接器603设置在杆体601的底端，与杆体601配合设置；第一耳机电连接器603并不在杆体601的外侧壁上。第二耳机电连接器604设置在耳塞602的外侧壁605上，与杆体601向底端延伸的一侧相对的位置(或称朝向杆体601向底端延伸的一侧的位置)。
在一些实施例中，第一耳机电连接器603和第二耳机电连接器604通过抗干扰器件与电源管理单元的两个电极分别电连接。该抗干扰器件可以是磁珠或电阻等占用空间较小的器件。
示例性的，参见图6B所示的电路图，电源管理单元可以包括电池充放电接口，用于测量电量的电量计集成电路(integrated circuit，IC)，保护IC，以及电源管理集成电路(power management integrated circuit，PMIC)等。其中，PMIC具有充电电路和压降调节电路等电路的功能。第二耳机电连接器通过磁珠，与电池充放电接口电连接，并通过电池充放电接口与PMIC输入端的正极电连接，PMIC进行升压/降压等处理后的输出端的正极通过电量计IC与电池的正极和保护IC的正极电连接。第一耳机电连接器通过磁珠接地(GND)。并且，PMIC和保护IC的负极均接地。也就是说，第一耳机电连接器通过磁珠与PMIC和保护IC的负极电连接，即第一耳机电连接器通过磁珠与电源管理单元的负极电连接。并且，如图6B所示，PMIC还与系统其他电路电连接，从而在对电池中的电量进行电压调节等处理后，输出给系统其他电路进行供电。
在一些实施例中，耳机本体内部的电路板可以为软硬结合板，即软板(也称柔性电路板(flexible printed circuit，FPC))和硬板(即印制电路板或称印刷电路板)相结合的电路板。例如，该电路板可以包括第一硬板、第二硬板以及用于电连接第一硬板和第二硬板的软板。其中，第一硬板为主板，音频模块中的其他电路(例如音频输出电路)，电源管理单元中的充电电路、防护电路，以及无线通信模块中的数据处理电路等主要设置在主板上。第二硬板上可以设置有麦克风收音电路。软板上可以设置有用于连接第一硬板和第二硬板的排线。第二硬板可以设置在杆体的底部。软板可以设置于杆体内部。第一硬板可以设置于耳塞内部。
在一些实施例中，图6A所示的第一耳机电连接器603与耳机本体600中电源管理单元的一个电极电连接，耳塞602外侧壁605上与杆体601向底端延伸的一侧相对的位置可以设置有开孔，第二耳机电连接器604穿过该开孔与耳机本体600中电源管理单元的另一个电极 电连接。
在一些实施例中，第一耳机电连接器通过第一抗干扰器件与第二硬板上的电路的负极电连接。其中，第一抗干扰器件可以设置在第二硬板上的任意位置。由于电路板上各电路的负极通常电连接在一起(例如均接地)，因而当第一耳机电连接器通过第一抗干扰器件与第二硬板上的电路的负极或其他电路的负极电连接时，第一耳机电连接器通过第一抗干扰器件与电源管理单元的负极以及电源模块的负极电连接。
这样一来，当第一耳机电连接器和第二耳机电连接器分别与耳机盒中的第一盒电连接器和第二盒电连接器建立电连接时，第一耳机电连接器可以从耳机盒接收信号，该信号中的高频、高压干扰信号经过第一抗干扰器件的抑制后，输入电源管理单元，从而再通过电源管理单元的处理，输入耳机本体中的电池进行充电。在不充电的情况下，第一耳机电连接器从外部导入的高频、高压干扰信号，可以先被第一抗干扰器件抑制后，再进入电源管理单元及其他电路。因而，可以降低第一耳机电连接器从外部导入的ESD、浪涌等高频、高压干扰信号对电路系统的影响，提高耳机系统的稳定性。
示例性的，第二硬板的电路图可以参见图7。如图7所示，第二硬板上可以包括第一耳机电连接器的焊盘701，第二硬板上的电路负极702，第一抗干扰器件700的设置区域703以及连接线704。其中，区域703包括两个矩形焊接区，用于焊接第一抗干扰器件700。第一耳机电连接器通过焊盘701与第二硬板焊接，并通过PCB走线704与第一抗干扰器件703电连接，焊接在第二硬板上的第一抗干扰器件700，通过连接线与第二硬板上的电路负极702电连接，即与电源模块的负极电连接。另外，第二硬板上还可以包括第一收音孔706，麦克风及麦克风的设置区域707，以及麦克风收音电路中的其他器件等。
这样，在第二硬板上，只有一个焊盘用于焊接耳机电连接器。通过该焊盘焊接的第一耳机电连接器通过连接线连接到第一抗干扰器件。当采用万用表或其他工具测量第一耳机电连接器与第一抗干扰器件之间的电阻时，若该电阻几乎为0欧姆，则可以表明第一耳机电连接器通过PCB走线与第一抗干扰器件电连接，并未通过其他器件与第一抗干扰器件电连接；从而，第一耳机电连接器可以通过第一抗干扰器件连接到耳机本体中的其他电路。
此外，如图6A所示，杆体601底端还可以设置有一个或多个第二收音孔606。该第二收音孔606可以贯穿于第一耳机电连接器603，以使得用户的语音信号可以通过第二收音孔606和第二硬板上的第一收音孔传入第二硬板上的麦克风，实现麦克风的收音功能。
其中，杆体底部的面积较小，例如直径可以为5mm。设置于杆体底部的第二硬板的面积也较小，例如面积可以为5mm×5mm。因而，用于抑制ESD、浪涌等高频、高压干扰信号的第一抗干扰器件占用的空间也应较小。示例性的，该第一抗干扰器件可以为磁珠或电阻。
在一些实施例中，为了防止由于安装误差导致的器件无法安装的问题，电路板上的第一耳机电连接器与其他器件之间的距离应大于预设距离1(例如0.5mm)。为了避免距离太近而导致ESD、浪涌等高频、高压干扰信号直接导入其他信号，电路板上用于连接第一耳机电连接器和抗干扰器件的PCB走线704与其他PCB走线(包括电路板上的焊盘)之间的距离应大于预设距离2(例如8mil)。
示例性的，图6A所示的第一耳机电连接器603，具体可以为如图8中的(a)所示的，与杆端相配合的半球形导电体81。在一些实施例中，整个半球形导电体81可以为导电材料。例如，该导电材料可以为金属或合金等。在另一些实施例中，该半球形导电体81通过在半球形塑料体的外表面镀上导电材料来形成；该种情况下，第一耳机电连接器的重量较小，耳机本体更为轻便。并且，如图8中的(a)所示，杆体80底部的第二硬板82形成卡槽83和卡 槽形焊盘84。如图8中的(b)所示，该导电体81上设置有卡扣部件811和连接部件812。其中，该卡扣部件811可以为与卡槽83的形状和大小相匹配，且向内形成凸起(或称向内伸出的台阶)。该连接部件812可以为与卡槽形焊盘84的形状和大小相匹配，且向内形成凸起(或称向内伸出的台阶)。该卡扣部件811卡扣于卡槽83所在的位置；该连接部件812焊接于卡槽形焊盘84所在的位置，从而使得该导电体81与第二硬板82相连。可以理解的是，卡槽83和卡槽形焊盘84的位置也可以互换。另外，导电体81还可以包括其他部件，用于将导电体81固定于杆体80的底端。例如，如图8中的(b)所示，导电体81包括伸出外部的部件813和部件814，可以通过胶体与杆体80的外壳粘接在一起，从而使得导电体81固定于杆体80的底端。
此外，如图8中的(a)和(b)所示，导电体81上设置有三个第二收音孔，即收音孔815、收音孔816和收音孔817。其中，收音孔815和收音孔816(即第一开孔和第二开孔)穿出导电体81设置，也可以说收音孔815和收音孔816设置在导电体81的外壁上。且收音孔815和收音孔816的直径较小，例如为0.8mm，明显小于图5C中的(a)所示的收音孔506的直径。收音孔815和收音孔816通过导电体81内部的管道818连通，管道上朝向第二硬板82的一侧开设有收音孔817(即第三开孔)，该收音孔817从管道818开始朝第二硬板82所在的一侧延伸，直至穿出导电体81。收音孔815、收音孔816和收音孔817呈T型结构。该种结构的第二收音孔在不设置防尘网的情况下，也可以防止灰尘和水进入耳机本体内部，达到防尘防水的效果。并且，收音孔817的位置可以与第二硬板82上的第一收音孔706的位置相对。用户的语音信号可以通过收音孔815和收音孔816传到收音孔817，并通过收音孔817传到第一收音孔706，从而传到第二硬板82上的麦克风。
可以理解的是，设置于杆体底端的第一耳机电连接器也可以为图8所示情况之外的其他形态，本申请实施例不予限定。例如，第一耳机电连接器也可以为弹片、接触垫等。
在一些实施例中，在第一耳机电连接器通过第一抗干扰器件，与耳机本体的电源模块相连，从而抑制ESD、浪涌等高频、高压干扰信号的基础上，第二电连接器可以不经过抗干扰器件而直接与耳机本体的电源模块电连接。
在另一些实施例中，在第一耳机电连接器通过第一抗干扰器件，与耳机本体的电源模块相连，从而抑制ESD、浪涌等高频、高压干扰信号的基础上；第二电连接器可以通过第二抗干扰器件接入耳机本体的电路系统，从而能够更好地抑制ESD、浪涌等高频、高压干扰信号。
其中，用于抑制ESD、浪涌等高频、高压干扰信号的第二抗干扰器件，可以为占用空间较小的磁珠、电阻等器件，也可以为占用空间较大的，用于抑制高频、高压干扰信号的其他器件。例如，当第二电连接器设置在如图6A所示的位置时，由于耳塞部分的空间较大，因而第二抗干扰器件既可以为磁珠、电阻，也可以为其他器件，本申请实施例不予限定。
示例性的，图6A所示的第二耳机电连接器604，具体可以为图9A和图9B中的(a)和(b)所示的导电贴片91，该导电贴片91焊接在软板92上，并通过磁珠与第一硬板上电源管理单元的正极电连接，即与电源模块的正极电连接。耳机本体的外壳上设置有开孔，该导电贴片91可以从该开孔伸出，从而暴露于耳机本体之外，以方便与盒电连接器相接触。其中，该导电贴片91可以先焊接在软板92上后，再与软板92一起从耳塞的外壳93的内部装入。并且，安装时，导电贴片91的周围可以涂有粘结材料(例如热熔胶)，以使得导电贴片固定在耳塞的外壳93上。示例性的，参见图9C，导电贴片91可以通过第一硬板上94上设置的磁珠95，与第一硬板94上电源管理单元的正极电连接。其中，磁珠95可以通过磁珠焊盘96焊接在第一硬板94上。
其中，软板92可以在杆体80内部沿着杆体80的配置方向设置，以连接杆体80底部的第二硬板82和耳塞内部的第一硬板。另外，耳机本体内的电池也可以为长条形状，在杆体80内部沿着杆体80的配置方向设置。
在一些实施例中，如图10所示，耳机本体的腔体内可以包括多个硬板，以及用于连接多个硬板的软板。其中，第二硬板可以为设置于杆体底部的硬板1001，第一耳机电连接器及对应的磁珠可以设置在硬板1001上。第一硬板可以包括图10所示的硬板1002-1006。电池可以通过软板1007上的焊点1008焊接在软板1007上，从而通过软板1007和第一硬板电连接。第二耳机电连接器可以设置在软板上，并通过第一硬板中的硬板1005上的磁珠，与第一硬板上的电源管理单元电连接。其中，硬板1005上可以包括部分或全部电源管理单元，例如硬板5上设置有PMIC等。硬板1002-1006上还可以包括无线通信模块中的数据处理电路，音频处理电路等现有无线耳机中具有的其他电路，具体可以参见现有技术，本申请实施例不予赘述。
需要说明的是，在现有的一些无线耳机中，耳机电连接器可以通过瞬态二极管(transient voltage suppressor，TVS)与电源模块的电极电连接。TVS器件通过将静电干扰信号卸放到电路系统的接地端，通过接地端与大地之间形成的电容来处理卸放的电能，从而降低静电干扰信号对无线耳机电路系统的影响。而实际上，由于无线耳机的体积较小，整个电路系统较小，电路系统接地端的配置面积也较小，接地端与大地之间形成的电容处理电能的能力也较小，因而难以实现将高能量的静电信号卸放到接地端的效果，静电干扰信号仍然可能会击穿耳机本体的电路系统中的器件，或对电路系统造成其他的干扰和影响，降低耳机系统的稳定性。
而在本申请实施例中，磁珠或电阻等抗干扰器件可以抑制和衰减静电、浪涌等产生的高频、高压干扰信号(例如可以将8000V的高压干扰信号降低到3000V)，从而阻止高频、高压干扰信号进入耳机本体的电路系统，从而可以减小干扰信号对耳机本体的电路系统的干扰和影响，提高无线耳机系统的稳定性。
此外，由于磁珠一般用于耐受电流较小的场景，而无线耳机中的电流较小，因而可以通过磁珠来抑制高频、高压干扰信号，达到降低干扰的目的。
可以理解的是，设置于耳塞外侧壁上的第二电连接器也可以为图9A所示情况之外的其他形态，本申请实施例不予限定。例如，第二电连接器也可以为pogo pin、插针等。
在其他一些实施例中，图6A所示的第一耳机电连接器也可以通过第一抗干扰器件和连接线与电源管理单元的正极连接；第二耳机电连接器也可以与电源模块的负极电连接。
其中，由于杆体底端的第一耳机电连接器通常会与用户的脸部接触，因而与杆体底端的第一耳机电连接器与电源管理单元的正极电连接相比，当杆体底端的第一耳机电连接器通过接地与电源管理单元的负极电连接时，可以较好地避免用户出汗时由于电离而导致的第一耳机电连接器的腐蚀等影响。
可以理解的是，第一耳机电连接器和第二耳机电连接器还可以设置在耳机本体上的其他位置。第一耳机电连接器或第二耳机电连接器中的至少一个，可以通过抗干扰器件后再与耳机本体电源模块的电极连接。并且，第一耳机电连接器和第二耳机电连接器还可以在耳机本体上分散设置。这样，两个耳机电连接器之间的距离较远，每个耳机电连接器在耳机本体内部均能够有足够的空间来设置抗干扰器件，从而可以减小ESD、浪涌等高频、高压干扰信号对耳机本体中电路系统的影响，并降低电路设计的难度。
例如，如图11中的(a)所示，第一耳机电连接器位于杆体底端，第二耳机电连接器位于耳塞外侧壁上除图6A所示位置以外的其他位置。
再例如，如图11中的(b)所示，第一耳机电连接器位于杆体底端，第二耳机电连接器 位于杆体外侧壁上靠近杆体顶部的位置。
再例如，如图11中的(c)所示，第一耳机电连接器位于杆体底端，第二耳机电连接器位于杆体外侧壁上，且两个耳机电连接器之间的距离大于或者等于第一预设值(例如可以为1cm)。
在图11中的(a)、(b)或(c)所示的情况下，在一些实施例中，耳机本体的腔体内可以包括上述第一硬板、第二硬板和软板。第一耳机电连接器可以通过抗干扰器件与第二硬板上的电路的电极电连接，第二硬板上电路的电极通过软板与第一硬板上电源模块的电极电连接。第二耳机电连接器可以设置在软板上，并通过抗干扰器件和软板与第一硬板上电源模块的另一个电极电连接。
再例如，第一耳机电连接器和第二耳机电连接器均设置在杆体外侧壁上，且两个耳机电连接器所在位置之间的距离大于或者等于第二预设值(例如可以为2cm)。示例性的，如图12中的(a)所示，第一耳机电连接器和第二耳机电连接器均设置在杆体外侧壁上，且一个靠近杆体顶部，另一个靠近杆体底部。在一些实施例中，耳机本体的腔体内可以包括上述第一硬板、软板和第三硬板，软板用于连接第一硬板和第三硬板，第三硬板可以设置于杆体内部。靠近杆体底部的耳机电连接器可以通过抗干扰器件与第三硬板上电路的电极电连接，第三硬板上电路的电极通过软板与第一硬板上电源模块的电极电连接。靠近杆体顶部的耳机电连接器可以设置在软板上，通过抗干扰器件和软板与第一硬板上电源模块的另一个电极电连接。
再例如，如图12中的(b)所示，第一耳机电连接器设置在杆体外侧壁上，第二耳机电连接器设置在耳塞外侧壁上。在一些实施例中，耳机本体的腔体内可以包括上述第一硬板、软板和第三硬板，软板用于连接第一硬板和第三硬板，第三硬板可以设置于杆体内部。杆体外侧壁上的第一耳机电连接器可以通过抗干扰器件与第三硬板上电路的电极电连接，第三硬板上电路的电极通过软板与第一硬板上电源模块的电极电连接。耳塞外侧壁上的耳机电连接器可以设置在软板上，通过抗干扰器件和软板与第一硬板上电源模块的另一个电极电连接。
再例如，第一耳机电连接器和第二耳机电连接器均设置在耳塞外侧壁上，且两个耳机电连接器所在位置之间的距离大于或者等于第三预设值(例如可以为1cm)。示例性的，如图12中的(c)所示，无线耳机包括杆体和耳塞，一个耳机电连接器设置在耳塞靠近顶部的位置，另一个耳机电连接器设置在耳塞靠近底部的位置。在一些实施例中，耳机本体的腔体内可以包括上述第一硬板，两个耳机电连接器可以设置在第一硬板上，且通过抗干扰器件分别与第一硬板上电源模块的两个电极电连接。在另一些实施例中，耳机本体的腔体内可以包括上述第一硬板和软板，软板可以用于连接第一硬板上的信号，两个耳机电连接器可以设置在软板上，并通过抗干扰器件和软板分别与第一硬板上电源模块的两个电极电连接。在另一些实施例中，耳机本体的腔体内可以包括上述第一硬板，设置在杆体内部的第四硬板，以及用于连接第一硬板和第二硬板的软板。两个耳机电连接器可以设置在软板上，并通过抗干扰器件和软板分别与第一硬板上电源模块的两个电极电连接。
在其他一些实施例中，无线耳机包括耳塞但不包括杆体，第一耳机电连接器和第二耳机电连接器均设置在耳塞外侧壁上，且两个耳机电连接器所在位置之间的距离大于或者等于第三预设值。
在图11-图12所示情况下，分散设置的第一耳机电连接器或第二耳机电连接器中的至少一个，也可以通过抗干扰器件后再与耳机本体电源模块的电极连接。
其中，当耳机电连接器设置于杆体外侧壁上，朝向耳塞的一侧(比如图12中的(b)等 所示的情况)时，耳机电连接器容易被杆体和用户的脸部遮挡，从而使得耳机本体看起来更为简洁美观。
当以上描述的第一耳机电连接器和第二耳机电连接器分别与耳机盒中的第一盒电连接器和第二盒电连接器接触，并建立电连接后，耳机盒可以通过该电连接为耳机本体充电。
例如，在一种情况下，在第一耳机电连接器与第一盒电连接器接触后建立电连接，第二耳机电连接器与第二电连接器接触后建立电连接，耳机盒可以通过该电连接，自动为第一耳机电连接器和第二耳机电连接器所在的耳机本体中的电池充电。
在另一种情况下，在第一耳机电连接器与第一盒电连接器接触后建立电连接，第二耳机电连接器与第二电连接器接触后建立电连接，且耳机盒通过盖子附近设置的接近光传感器、环境光传感器、压力传感器等传感器，检测到耳机盒的盖子被盖合后，可以通过该电连接，为第一耳机电连接器和第二耳机电连接器所在的耳机本体中的电池充电。
在另一种情况下，在第一耳机电连接器与第一盒电连接器接触后建立电连接，第二耳机电连接器与第二电连接器接触后建立电连接，且耳机盒检测到用户指示充电操作后，可以通过该电连接为第一耳机电连接器和第二耳机电连接器所在的耳机本体中的电池充电。示例性的，用户指示充电的操作可以为用户按下/触摸充电控件的操作，该充电控件可以设置于耳机盒的外表面上。
类似于发起为耳机本体进行充电，耳机盒还可以停止为耳机本体充电。例如，耳机盒在检测到盒电连接器与任意一个或两个耳机本体的耳机电连接器断开电连接后，可以停止为断开电连接的耳机本体充电。再例如，耳机盒在检测到任意一个或两个耳机本体从耳机盒中被取出后，可以停止为取出的耳机本体充电。再例如，耳机盒在检测到用户指示停止充电的操作后，停止为耳机本体充电。
此外，上述耳机电连接器用于与盒电连接器电连接，可以由各种导电材料制作而成，例如铜等金属，本申请实施例对具体材料不予限定。
