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，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。当电连接器与耳机盒上的电连接器接触时，可以传输电流从而通过耳机盒为耳机本体充电。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，电路板上不同信号线之间也要间隔一定的距离，因而杆体底部电连接器附近的空间较为紧张。
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。
其中，每个耳机本体可以包括两个电连接器(或称触点)，这两个电连接器与耳机本体中系统电源的两个电极(即正极和负极，或称阳极和阴极)分别电连接。并且，这两个电连接器在耳机本体上分散设置。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。也就是说，这两个电连接器并不是都设置在耳机本体的杆体底端，只有一个电连接器设置在杆体底端，与该电连接器分散设置的另一个电连接器设置在杆体外侧壁上或耳塞外侧壁上；或者，两个电连接器分散设置于杆体外侧壁上；或者，两个电连接器分散设置在耳塞的外侧壁上；或者，一个电连接器设置在杆体的外侧壁上，另一个电连接器设 置在耳塞的外侧壁上。这样，耳机本体内部可以有更为充足的空间来设置每个电连接器。
此外，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，可以通过充电盒22为耳机本体211中的电池进行充电。
随着无线耳机的体积越来越小，静电放电(electro-static discharge，ESD)、浪涌等对无线耳机的干扰问题越来越严重。无线耳机暴露在外面的电连接器，更容易将ESD、浪涌等产生的高频、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。
为了降低ESD、浪涌等高频、高压干扰信号的影响，可以将无线耳机电连接器输入的电信号经过抗干扰器件后，再接入无线耳机内部的电路系统。该抗干扰器件可以用于抑制电连接器从外部导入的ESD、浪涌等高频、高压干扰信号，减小这些干扰信号对无线耳机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。
而增加抗干扰器件将使得杆体底部的空间更为紧张，从而增大了杆体内部电路设计的难度。
在本申请实施例中，分散设置的每个电连接器，在耳机本体内部都可以有较为充足的空间来设置抗干扰器件，从而使得耳机本体内部的电路设计较为简单。
示例性的，图3示出了一种无线耳机300的结构示意图。该无线耳机300可以包括至少一个处理器301、至少一个存储器302、无线通信模块303、音频模块304、电源模块305以及输入/输出接口306等。该处理器可以包括一个或多个接口，用于与无线耳机300的其他部件相连。该无线耳机300通过耳机盒进行收纳。

在另一些实施例中，耳机盒内还可以包括处理器，存储器等部件。该存储器可以用于存储应用程序代码，并由耳机盒的处理器来控制执行，以实现耳机盒的各项功能。例如。耳机盒的处理器通过执行存储在存储器中的应用程序代码，在检测到无线耳机被放入耳机盒，且耳机盒的盖子被盖合后向无线耳机充电等。
此外，该耳机盒上还可以设置有充电接口，用于耳机盒为自身的电池进行充电。耳机盒内还可以包括无线充电线圈，用于对耳机盒自身的电池进行无线充电。可以理解的是，该耳机盒还可以包括其他部件，此处不再一一说明。
在本申请的一些实施例中，图4A示出了无线耳机中的一种耳机本体40的结构示意图。该耳机本体40可以包括外壳41和内部部件42。内部部件42设置于外壳41形成的腔体内。内部部件42可以包括上述无线通信模块303、音频模块304、电源模块305等模块中的器件。耳机本体还可以包括，与内部部件相连，分散设置在外壳上的第一耳机电连接器(即第一电连接器)43和第二耳机电连接器(即第二电连接器)44。
其中，分散设置在外壳上的第一耳机电连接器和第二耳机电连接器，暴露在耳机本体外部，以便于与盒电连接器接触从而建立电连接。第一耳机电连接器和第二耳机电连接器可以通过压接、焊接、卡扣、绕接等多种方式与内部部件相连。
并且，第一耳机电连接器和第二耳机电连接器分别与耳机本体电源模块的电极(即正极或负极，或称阳极或阴极)电连接，从而为耳机本体中的电池充电。电源模块可以为系统其他电路供电。对应的电路原理图可以参见图4B。在充电时，从耳机电连接器导入的充电信号可以进入电源模块，从而为电源模块中的电池充电。通常，电源模块的负极以及其他电路的负极均接地。
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，参见图4C，第一耳机电连接器和第二耳机电连接器 可以分别与电源管理单元的电极相连。在充电时，从耳机电连接器导入的充电信号可以先进入电源管理单元，并通过电源管理单元的处理后，再输入电池进行充电。并且，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。
图5A示出了一种耳机本体500的结构示意图。该耳机本体500可以包括杆体501，以及与杆体501顶部相连的耳塞502。杆体501和耳塞502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501的腔体内部。音频模块304中的扬声器组件可以设置于耳塞502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501的底端，且暴露于耳机本体500的外部。第二耳机电连接器设置在耳机本体500除杆体501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(或称朝向杆体向底端延伸的一侧的位置)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501的底端，第二耳机电连接器设置在耳塞502外侧壁505上的任意位置，以与第一耳机电连接器分散设置。
例如，如图5A所示，第一耳机电连接器503设置在杆体501底部的杆端，或者说第一耳机电连接器503设置在杆体501的底端，与杆体501配合设置；第一耳机电连接器503并不在杆体501的外侧壁上。第二耳机电连接器504设置在耳塞502外侧壁505上，且与杆体501相对的位置(或称朝向杆体501的位置)。
其中，图5A所示的第一耳机电连接器503可以与耳机本体500中系统电源的一个电极电连接；耳塞502外侧壁505上与杆体501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504穿过该开孔与耳机本体500中系统电源的另一个电极电连接。
在一些实施例中，参见图5B所示的电路图，第一耳机电连接器503和第二耳机电连接器504分别与电源管理单元的两个电极分别电连接。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5B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(柔性电路板)和硬板(硬质电路板)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电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。
此外，如图5A所示，杆体501底端还可以设置有一个或多个第二收音孔605。该第二收音孔605可以贯穿于第一耳机电连接器503，以使得用户的语音信号可以通过第二收音孔605和第二硬板上的第一收音孔传入第二硬板上的麦克，实现麦克收音。
在一些实施例中，第一耳机电连接器与第二硬板上的电路的负极电连接。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与第二硬板上的电路的负极电连接时，第一耳机电连接器与电源管理单元的负极以及系统电源的负极电连接。
当第一耳机电连接器和第二耳机电连接器与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输入的电信号，该电信号通过电源管理单元的处理后，输入电池进行充电。
其中，第一耳机电连接器与第二耳机电连接器可以为相同的类型，也可以为不同的类型，还可以分别有多种不同的安装方式。示例性的，图5A所示的第一耳机电连接器503，具体可以为如图6中的(a)所示的，与杆端相配合的半球形导电体61。在一些实施例中，整个半球形导电体61可以为导电材料，例如金属或合金等。在另一些实施例中，该半球形导电体61通过在半球形塑料体的外表面镀上导电材料制成；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6中的(a)所示，杆体60底部的第二硬板62形成卡槽63和卡槽形焊盘64。如图6中的(b)所示，该导电体61上设置有卡扣部件611和连接部件612。其中，该卡扣部件611可以为与卡槽63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612可以为与卡槽形焊盘64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611卡扣于卡槽63所在的位置；该连接部件612焊接于卡槽形焊盘64所在的位置，从而使得该导电体61与第二硬板62相连。另外，导电体61还可以包括其他部件，用于将导电体61固定于杆体60的底端。例如，如图6中的(b)所示，导电体61包括伸出外部的部件613和部件614，可以通过胶体与杆体60的外壳粘接在一起，从而使得导电体61固定于杆体60的底端。
示例性的，图5A所示的第二耳机电连接器504，具体可以为图7A所示的导电贴片71，该导电贴片71贴在软板72上，并与电源管理单元的正极连接，即与系统电源的正极连接。耳机本体的外壳上设置有开孔，该导电贴片71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71可以先贴在软板72上后，再与软板72一起从外壳内部装入。
示例性的，图5A所示的第二耳机电连接器504，具体可以为图7A和图7B中的(a)和(b)所示的导电贴片71，该导电贴片71焊接在软板72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71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71可以先焊接在软板72上后，再与软板72一起从耳塞的外壳73的内部装入。并且，安装时，导电贴片71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73上。示例性的，参见图7C，导电贴片71可以与第一硬板74上电源管理单元的正极电连接。
其中，软板72可以在杆体60内部沿着杆体60的配置方向设置，以连接杆体60底部的 第二硬板62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，在杆体60内部沿着杆体60的配置方向设置。
在一些实施例中，如图8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801，第一耳机电连接器可以设置在硬板801上。第一硬板可以包括图8所示的硬板802-806。电池可以通过软板807上的焊点808焊接在软板807上，从而通过软板807和第一硬板电连接。第二耳机电连接器可以设置在软板上，并通过软板与第一硬板中的硬板805上的电源管理单元电连接。其中，硬板805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802-806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。
可以理解的是，第一耳机电连接器也可以为图6所示情况之外的其他形态，第二电连接器也可以为图7A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，第二电连接器也可以为pogo pin、插针等。
在其他一些实施例中，在分散设置的第一耳机电连接器和第二耳机电连接器中，至少一个耳机电连接器可以通过抗干扰器件与耳机本体的系统电源的电极(正极或负极)电连接。该抗干扰器件可以用于衰减从耳机电连接器，导入的ESD、浪涌等产生的高频、高压干扰信号，减小从电连接器导入的高频、高压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。例如，该抗干扰器件可以为占用空间较小的磁珠、电阻等器件。
例如，在图5A所示的情况下，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较为充分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，减小干扰信号对耳机本体内部电路系统的影响，并降低电路设计的难度。示例性的，图5A所示的第一耳机电连接器可以通过第一抗干扰器件和连接线与系统电源或电源管理单元的负极连接；第二耳机电连接器可以与系统电源的正极电连接。
在其他一些实施例中，图5A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系统电源或电源管理单元的正极连接；第二耳机电连接器也可以与系统电源的负极电连接。
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。
在另一些实施例中，在第一耳机电连接器设置在杆体501的底端的情况下，与第一耳机电连接器分散设置的第二耳机电连接器，可以位于耳塞502外侧壁上除图5A所示位置以外的其他位置。例如，第二耳机电连接器可以位于如图9A中的(a)-(c)所示的位置。再例如，如图9B中的(a)-(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靠近杆体顶部的一端，即远离杆体底部的一端。
在其他一些实施例中，如图10中的(a)或(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，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)。
这样，分散设置的每个耳机电连接器在耳机本体内部均能够有较为充分的空间设置抗干扰器件，从而可以减小ESD、浪涌等高频、高压干扰信号对电路系统的影响，并降低耳机本体内部电路设计的难度。
在其他一些实施例中，第一耳机电连接器和第二耳机电连接器，可以分散设置于除杆体底端以外的其他位置。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11中的(a)或(b)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。
再例如，如图12中的(a)-(c)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。
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13所示，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。
这样，两个耳机电连接器之间的距离较远，分散设置的每个耳机电连接器在耳机本体内部均能够有较为充分的空间设置抗干扰器件，从而可以抑制ESD、浪涌等高频、高压干扰信号，并降低电路设计的难度。
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9B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。
耳机盒用于收纳上述无线耳机。当上述无线耳机收纳于耳机盒中时，耳机盒与耳机本体之间可以过盈连接。耳机盒中可以设置有分别与盒电源模块的两个电极相连，且与耳机本体的第一耳机电连接器和第二耳机电连接器分别对应的第一盒电连接器(即第三电连接器)和第二盒电连接器(即第四电连接器)。第一盒电连接器和第二盒电连接器分别与第一耳机电连接器和第二耳机电连接器配合使用。在一些实施例中，耳机本体和耳机盒的对应位置分别设置有磁吸部件，当耳机本体放入耳机盒中时，通过磁吸器件之间的相互吸引可以使得耳机本体固定于耳机盒中。
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从而建立电连接后，耳机盒可以通过该电连接为耳机本体中的电池充电。
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。
与第一耳机电连接器和第二耳机电连接器类似，第一盒电连接器和第二盒电连接器也可以分别有多种不同的结构和安装方式。并且，当无线耳机上第一耳机电连接器和第二耳机电连接器在耳机本体上的位置不同时，与第一耳机电连接器和第二耳机电连接器配合使用的，第一盒电连接器和第二盒电连接器在耳机盒中的位置也不同。
示例性的，当第一耳机电连接器和第二耳机电连接器位于图5A所示的位置时，若无线耳机在耳机盒中竖向收纳，则与第一耳机电连接器配合使用的第一盒电连接器1401的位置，可以参见图14中的(a)所示的顶视图以及图14中的(b)所示的侧视图。如图14所示，该第一盒电连接器1401为碗状的导电片(或称碗状触点)。与第二耳机电连接器配合使用的第二盒电连接器1501的位置，可以参见图15中的(a)所示的俯视图以及图15中的(b)所示的侧视图。并且，如图2中的(a)所示，无线耳机可以放入耳机盒中。如图15所示，该第二盒电连接器1501为弹簧针或pogo pin。

第二子腔体1502的侧壁上设置有第二盒电连接器1501。该第二盒电连接器1501与第二耳机电连接器504配合使用。当耳机本体收纳于耳机盒中时，该第二盒电连接器1501与第二耳机电连接器504相互接触。
需要注意的是，无线耳机包括两个耳机本体，每个耳机本体包括一对第一耳机电连接器和第二耳机电连接器，则无线耳机包括两对第一耳机电连接器和第二耳机电连接器。相对应的，耳机盒上可以包括与两对第一耳机电连接器和第二耳机电连接器配合使用的，两对第一盒电连接器和第二盒电连接器。
再示例性的，当第一耳机电连接器和第二耳机电连接器位于图5A所示的位置时，若无线耳机在耳机盒中卧向(或称横向)收纳，则第一盒电连接器1601和第二盒电连接器1602的位置示意图可以参见图16。
