在一些实施例中，对讲设备2可以包括第一外接接口201。也即，对讲设备2可以提供有第一外接接口201，用于扩展对讲设备2的功能，通过连接不同的外接模块可以实现不同的功能。例如，外接模块可以包括外接通信模块、存储模块、故障检测模块和电源检测模块等。外接通信模块可以作为骨传导耳机1和对讲设备2之间进行蓝牙通信的媒介，存储模块可以存储对讲设备2的信息，故障监测模块和电源监测模块可以保证终端的稳定运行。第一外接接口201还可以用于供外部终端对对讲设备2进行编程等。第一外接接口201可以包括多个间隔设置的触点(图1已示出，但未标注)，例如为7个触点。
在一些实施例中，外接通信模块3可以包括第二外接接口301和第二蓝牙模块302。外接通信模块3可拆卸地设置于对讲设备2，例如外接通信模块3 以卡接的方式固定于对讲设备2。第二外接接口301也可以具备和第一外接接口201同样多的触点。外接通信模块3安装在对讲设备2时，第一外接接口201和第二外接接口301连接。外接通信模块3通过第一外接接口201和第二外接接口301耦接对讲设备2。对讲设备2可以通过外接通信模块3实现蓝牙功能。
如图2所示，对讲设备2可以通过外接通信模块3和骨传导耳机1建立蓝牙连接。在对讲设备2和骨传导耳机1通过外接通信模块3建立起蓝牙连接后，可以使用骨传导耳机1控制对讲设备2，例如可以使用骨传导耳机1接听对讲设备2所接收到的音频，也可以使用骨传导耳机1的麦克风发送相应的语音，还可以控制对讲设备2的其他功能。当然，对讲设备2也可以控制骨传导耳机1。
在一些实施例中，在骨传导耳机1未被佩戴时，如果通过骨传导耳机1进行拾音或者语音播放，可能会导致无法有效地拾音或者使用者无法听到骨传导耳机1所传输的语音，此时可以通过对讲设备2进行拾音和/或语音播放，进而使得播放的语音能够被听到和/或有效地拾音。在骨传导耳机1被佩戴时，则可以通过骨传导耳机1进行拾音和/或语音播放，如此便于使用者发送语音或者听到播放的语音。为了能够根据实际使用情况对设备功能进行切换，在一些实施例中，可以通过传感器进行佩戴方式的感应或设备激活等。
在一些实施例中，骨传导耳机1还包括传感器组件17，用于检测骨传导耳机1是否被佩戴。在一些实施例中，骨传导耳机1在被佩戴时，可以控制骨传导耳机1进行拾音和/或语音播报；骨传导耳机1在未佩戴时，可以控制对讲设备2进行拾音和/或语音播报。
在一些实施例中，用于感应是否佩戴骨传导耳机1的传感器组件17可以是加速度传感器、重力传感器、陀螺仪传感器、触摸传感器、距离传感器和接触传感器中的一个或多个。例如，可以在骨传导耳机1内设置陀螺仪传感器和加速度传感器，通过检测用户佩戴情况或佩戴姿势，根据实际情况选择激活设备。
在一些实施例中，具体的，传感器组件17例如包括光学传感器，通过发 射和/或接受相应的光信号来检测是否被佩戴。光学传感器可以是近光传感器，可以发射相应光信号，在骨传导耳机1被佩戴时会对光信号进行反射产生发射光，在骨传导耳机1未被佩戴时就不产生反射光，近光传感器可以通过是否接收反射光来检测骨传导耳机1是否被佩戴或者进行测距。在一些实施例中，近光传感器可以是红外近光传感器，需要说明的是，在其他实施例中根据实际情况还可以选择不同的传感器和不同传感器的组合方式，在此不做限制。
在一些实施例中，进一步的，骨传导耳机1和对讲设备2处于蓝牙连接状态下，在传感器组件17检测到骨传导耳机1被佩戴时，控制骨传导耳机1和对讲设备2中的骨传导耳机1用于进行拾音和/或语音播放，而骨传导耳机1和对讲设备2中的对讲设备2不用于进行拾音和/或语音播放。也即，在骨传导耳机1被佩戴时，通信系统是通过骨传导耳机1的麦克风工作进行拾音和/或扬声器工作进行语音播放。在一些实施例中，在传感器组件17检测到骨传导耳机1未被佩戴时，控制骨传导耳机1和对讲设备2中的对讲设备2进行拾音和/或语音播放，而骨传导耳机1和对讲设备2中的骨传导耳机1不用于进行拾音和/或语音播放。也即，在骨传导耳机1未被佩戴时，通信系统是通过对讲设备2的麦克风工作进行拾音和/或扬声器工作进行语音播放。
在一些实施例中，在传感器组件17检测到骨传导耳机1未被佩戴时，骨传导耳机1和对讲设备2可以同时拾音，对讲设备2进行语音播放。在一些实施例中，在传感器组件17检测到骨传导耳机1被佩戴时，骨传导耳机1和对讲设备2可以同时拾音，骨传导耳机1进行语音播放。通过传感器组件17检测骨传导耳机1是否被佩戴，进而便于通信系统实现上述自动切换，避免语音信息被遗漏，可以适应不同的使用场景，提高工作效率。
在一些实施例中，为了便于骨传导耳机和对讲设备2快速地进行蓝牙连接，可以在骨传导耳机1和对讲设备2之间快速地交换蓝牙地址，以便于快速进行配对。如图2所示，骨传导耳机1可以具有NFC近场通信功能，具体可以包括第一NFC模块102，可以用于实现近场通信功能。而外接通信模块3还可 以包括第二NFC模块303，可以使得对讲设备2可以实现近场通信。
在一些其他实施例中，骨传导耳机还可以具有ZigBee通信模块。例如，对讲设备2将请求配对的信号发送到骨传导耳机1，响应于接收到的配对请求信息，骨传导耳机1将个人识别码请求信息发送到对讲设备2，以进行与骨传导耳机1的配对。
在一些实施例中，个人识别码由用户输入到对讲设备2，将所输入的个人识别码发送骨传导耳机1，检查骨传导耳机1所接收到的个人识别码是否与存储在骨传导耳机中的个人识别码对应。如果所接收到的个人识别码不与其存储在骨传导耳机中的个人识别码对应，则骨传导耳机1将个人识别码请求信息重新发送到对讲设备2。如果所接收到的个人识别码与存储在骨传导耳机中的个人识别码对应，则骨传导耳机1与对讲设备2完成配对。
在一些实施例中，骨传导耳机1和对讲设备2可以通过第一NFC模块102和第二NFC模块303的近场通信交换蓝牙地址，使得第一蓝牙模块101和第二蓝牙模块302进行蓝牙配对以建立蓝牙连接。对于上述交换蓝牙地址而言，可以有以下方式：
第一种方式：骨传导耳机1将蓝牙地址发送给对讲设备2，可以节省对讲设备2搜索和选择骨传导耳机1的时间。也即，第一NFC模块102可以存储或者获取第一蓝牙模块101的蓝牙地址。第一NFC模块102和第二NFC模块303进行近场通信时，第一NFC模块102可以将蓝牙地址发送给第二NFC模块303，进而使得外接通信模块3可以获取到第一蓝牙模块101的蓝牙地址，实现蓝牙地址交换，进而可以进行快速配对和连接。
第二种方式：对讲设备2将蓝牙地址发送给骨传导耳机1，可以节省骨传导耳机1搜索和选择对讲设备2的时间。也即，第二NFC模块303可以存储或者获取第二蓝牙模块302的蓝牙地址。第一NFC模块102和第二NFC模块303进行近场通信时，第二NFC模块303可以将第二蓝牙模块302的蓝牙地址发送给第一NFC模块102，进而使得骨传导耳机1可以获取到第二蓝牙模块302的 蓝牙地址，实现蓝牙地址交换，进而可以进行快速配对和连接。
第三种方式：对讲设备2和骨传导耳机1均主动发送彼此的蓝牙地址，节省彼此之间进行搜索和选择的时间，实现快速配对和连接。也即，第一NFC模块102可以存储或者获取第一蓝牙模块101的蓝牙地址，第二NFC模块303可以存储或者获取第二蓝牙模块302的蓝牙地址。第一NFC模块10和第二NFC模块303进行近场通信时，第一NFC模块102和第二NFC模块303交换彼此的蓝牙地址，实现蓝牙地址的交换。
对讲设备2通过外接通信模块3的第二NFC模块303和骨传导耳机1的第一NFC模块102实现快速的蓝牙连接，如此可以使得对讲设备2可以快速匹配不同的骨传导耳机1。以工业现场作业为例，不同的工作人员配置不同的骨传导耳机1，比如两个工作人员可以共用一台对讲设备2，该两个工作人员在轮班时可以交替使用共用的对讲设备2，通过骨传导耳机1可以快速连接对讲设备2。在一个工作人员在值班时，使用其的骨传导耳机1和对讲设备2实现“一碰即连”，进而可以使用对讲设备2和骨传导耳机1组成的通信系统。在该工作人员下班，另一个工作人员开始值班时，该另一个工作人员同样也可以将骨传导耳机1和对讲设备2“一碰即连”，进而使用对讲设备2和骨传导耳机1组成的通信系统，形成“独立”和“共用”并存的作业逻辑，独立的是每个人可以使用自个的骨传导耳机1，共用的是对讲设备2。本实施例的通信系统，还可以将骨传导耳机1标识个人，进而可以多人使用同一台对讲设备2，可以实现快速切换，还可以实现考勤打卡、识别个人身份等作用。
对讲设备2和骨传导耳机1通过NFC近场通信的方式快速进行蓝牙配对进而建立蓝牙连接，骨传导耳机1被佩戴时能够释放使用者的双耳，通过骨传导的方式传递声音，能够减少周围环境的噪声对声音传输的影响，提升语音通信的质量，而且通过骨传导耳机1来播放对讲设备2所接收到的音频信号或者通过骨传导耳机1来拾取声音经对讲设备2传输至其他对讲设备2，能够避免传统对讲外放的方式，更加能够保护隐私，此外对于工厂车间等应用场景而言，使用 者在使用骨传导耳机1进行对讲通信的同时也能够注意到周围环境的变化，能够保证使用者的安全。
对于骨传导耳机1而言，第一NFC模块102可以为无源型NFC模块。第一NFC模块102可以存储有第一蓝牙模块101的蓝牙地址，可以向第二NFC模块303发送第一蓝牙模块101的蓝牙地址。当然，第一NFC模块102也可以是有源型NFC模块，可以发送第一蓝牙模块101的蓝牙地址，也可以接收到第二NFC模块303所发送过来的第二蓝牙模块302的蓝牙地址。同理，第二NFC模块303也可是无源型NFC模块，也可以是有源型NFC模块。
在一些实施例中，第一NFC模块102可以贴设于骨传导耳机1的电池组件上，如此安装方便且结构简单，还能够节省空间。在需要和对讲设备2进行蓝牙连接时，将骨传导耳机1的电池组件对应的位置靠近对讲设备2上的外接通信模块3，即可快速地进行蓝牙配对。
在一些实施例中，骨传导耳机1的靠接左耳和右耳的两端可以分别包括一个第一NFC模块102和一个第一蓝牙模块101，两端的两个第一蓝牙模块101可以通过TWS(True Wireless Stereo)建立连接。在实际进行配对过程中，可以通过所述靠接左耳和右耳的两端的任意一端的第一NFC模块102与第二NFC模块303进行通讯，从而实现所述靠接左耳和右耳的两端的任意一端的第一蓝牙模块101和第二蓝牙模块302的快速配对。
图3是根据本申请一些实施例所示的骨传导耳机的整体结构俯视示意图，图4是根据本申请一些实施例所示的骨传导耳机的整体结构爆炸示意图。
在一些实施例中，如图3所示，骨传导耳机还包括耳挂组件12，以传感器组件17包括光学传感器为例，耳挂组件在佩戴时靠近佩戴者耳根的位置上开设有透射所述光学传感器的光信号的窗口，可选地，窗口可以呈跑道形设置。关于窗口的详细说明可参见本申请图9的相关描述，此处不做赘述。
在一些实施例中，如图3和图4所示，骨传导耳机可以包括两个扬声器组件11、两个耳挂组件12、连接于两个耳挂组件12之间的后挂组件13、电池 组件14和控制电路组件15。
在一些实施例中，两个扬声器组件11分别对应连接两个耳挂组件12，耳挂组件12连接于后挂组件13和扬声器组件11之间。耳挂组件12可以形成有容纳空间120，其中一个耳挂组件12的容纳空间120用于容纳电池组件14，另一个耳挂组件12的容纳空间120用于容纳控制电路组件15。电池组件14用于给骨传导耳机1进行供电，控制电路组件15用于控制骨传导耳机1的工作和实现相应的操作。
在一些实施例中，骨传导耳机1包括棍咪组件16，用于拾取声音。棍咪组件16可转动地连接扬声器组件11。棍咪组件16可以包括弹性连接杆161和拾音组件162。棍咪组件16的数量可以为一个，其连接两个扬声器组件11中的一个，例如棍咪组件16可以连接与电池组件14所对应的扬声器组件11。当然，在其他一些实施例中，每个扬声器组件11均可以连接一个棍咪组件16。如图4所示，弹性连接杆161的一端连接扬声器组件11。弹性连接杆161的另一端连接拾音组件162。拾音组件162可以具有一个或者多个麦克风。例如，拾音组件162的麦克风数量大于或者等于2个，麦克风之间可以间隔设置。例如，一个麦克风位于拾音组件162远离扬声器组件11的端部，其他麦克风可以位于拾音组件162与端部连接的侧面。便于多个麦克风之间协同工作，能够起到降噪以及提升拾音质量等作用。骨传导耳机1能够将音频转化成机械振动，也即，扬声器组件11在播放相应的音频时，该音频对应的语音频段时会使得扬声器113产生相应的振动。在一些实施例中，弹性连接杆161可以设置成使得扬声器组件11所产生的语音频段的振动从弹性连接杆161的一端传递到弹性连接杆161的另一端时的平均振幅衰减率不小于预设衰减率阈值。例如，所述均振幅衰减率不小于35％。又例如，上述平均振幅衰减率不小于45％。再例如，平均振幅衰减率不小于50％。再例如，平均振幅衰减率不小于55％。再例如，上述振幅衰减率不小于60％。再例如，上述振幅衰减率不小于70％。
在实际的使用中，骨传导耳机1的扬声器组件11所产生的机械振动会对 棍咪组件16的拾音效果造成不良影响，如回声等，为此，将弹性连接杆161设置成使得扬声器组件11所产生的语音频段的振动从弹性连接杆161的一端传递到弹性连接杆161的另一端时的平均振幅衰减率不小于所述预设衰减率阈值(例如35％)，如此弹性连接杆161在振动传递的过程中可以有效地吸收振动，减少经弹性连接杆161的一端传递到另一端的振动幅度，进而减少了扬声器组件11所产生的振动而导致的拾音组件162的振动，能够有效地降低扬声器组件11的振动对拾音组件162的拾音效果的影响，提升拾音质量。
图5是根据本申请一些实施例所示的骨传导耳机中棍咪组件的结构拆解示意图。
在一些实施例中，如图5所示，弹性连接杆161可以包括棍咪弹性金属丝1611以及连接于棍咪弹性金属丝1611两端的接插部1612。也即棍咪弹性金属丝1611的两端各自连接有一个接插部1612。其中一个接插部1612用于与拾音组件162接插配合。另一个接插部1612用于和扬声器组件11接插配合。两个接插部1612的接插结构可以相同也可以不同，分别与拾音组件162和扬声器组件11相应的接插结构相适配。
在一些实施例中，棍咪弹性金属丝1611的弹性模量可以为70-90GPa。可选为，棍咪弹性金属丝1611的弹性模量为75-85GPa。可选为，棍咪弹性金属丝1611的弹性模量为80-84Gpa。可选为，棍咪弹性金属丝1611的弹性模量为81-83Gpa。棍咪弹性金属丝1611的材料可以为弹簧钢、钛、其他金属或非金属材料。通过设置棍咪弹性金属丝1611的弹性模量为70-90GPa，可以使得棍咪弹性金属丝1611具有良好地吸收振动的能力，可以满足棍咪组件16的吸振能力的要求，进而可以提高拾音组件162的拾音质量。
在一些实施例中，如图5所示，弹性连接杆161可以包括包覆于棍咪弹性金属丝1611外周的棍咪弹性覆层1613，棍咪弹性覆层1613的弹性模量为0.5-2Gpa。可选为，棍咪弹性覆层1613的弹性模量为0.8-1.5Gpa。可选为，棍咪弹性覆层1613的弹性模量为1.2-1.4Gpa。棍咪弹性覆层1613可以进一步覆盖部分 接插部1612，进而可以保护棍咪弹性金属丝1611和接插部1612。棍咪弹性覆层1613的材料可以为硅胶、橡胶、塑胶等。可选地，棍咪弹性覆层1613沿其长度方向可以开设有导线通道，导线通道可以和棍咪弹性金属丝1611并列间隔设置。接插部1612可以开设有连通导线通道的埋线槽，用于连接拾音组件162的导线组可以经相邻的接插部1612的埋线槽进入到导线通道内，进而再经另一个接插部1612进入到扬声器组件11内。
通过将棍咪弹性覆层1613的弹性模量设置为0.5-2Gpa，而且由于棍咪弹性覆层1613包覆在棍咪弹性金属丝1611外，可以将棍咪弹性金属丝1611所往外传递的振动进一步吸收，形成了内外协同吸振的效果，能够较大地提升棍咪组件16的吸振效果，有效地减少传递到拾音组件162的振动，提升拾音质量。
图6是根据本申请一些实施例所示的骨传导耳机中扬声器组件的结构一爆炸示意图。在一些实施例中，如图6所示，扬声器组件11可以包括第一扬声器壳体111、第二扬声器壳体112、扬声器113、转动件114以及压持件115。第一扬声器壳体111和第二扬声器壳体112配合连接，以形成用于容纳扬声器113的收容空间110。
第一扬声器壳体111可以与弹性连接杆161的一端接插配合。为了便于调节棍咪组件16的拾音位置，可以设置棍咪组件16能够相对于第一扬声器壳体111进行转动。在一些实施例中，扬声器组件11可以包括转动件114。第一扬声器壳体111可以开设有第一通孔1110。转动件114可转动地插设于第一通孔1110内，接插部1612可以与转动件114接插配合，以使得棍咪组件16可以相对于第一扬声器壳体111转动。
在一些实施例中，第一扬声器壳体111可以开设有与第一通孔1110间隔设置的第二通孔1111。第二通孔1111用于供耳挂组件12进行接插配合，进而使得扬声器组件11和耳挂组件12连接。其中，第一通孔1110和第二通孔1111均连通收容空间110。
具体地，第一扬声器壳体111可以包括相互连接的底壁1112和侧壁1113。 侧壁1113环绕连接底壁1112，第二扬声器壳体112盖设于侧壁1113远离底壁1112的一侧，以形成用于容纳扬声器113的收容空间110。第一通孔1110形成于底壁1112，第二通孔1111形成于侧壁1113。第一通孔1110可以形成于底壁1112邻近第二通孔1111的一侧，以使得第一通孔1110和第二通孔1111相邻。具体地，底壁1112具有背离收容空间110凸起的第一凸部1114，第一通孔1110形成于第一凸部1114，侧壁1113具有背离收容空间110凸起的第二凸部1115，第二通孔1111形成于第二凸部1115，第一凸部1114的凸起方向和第二凸部1115的凸起方向相互垂直，且第一凸部1114和第二凸部1115之间弧形连接。
通过底壁1112设置的第一凸部1114和侧壁1113设置的第二凸部1115，两者的凸起方向相互垂直且弧形连接，能够增强第一扬声器壳体111的结构强度和结构稳定性，而且转动件114嵌入到第一凸部1114的第一通孔1110内，第一凸部1114具有相应的高度可以使得棍咪组件16的转动不会受到第一扬声器壳体111的干扰，第一凸部1114和第二凸部1115的凸起方向相互垂直也可以减少耳挂组件12和棍咪组件16之间产生相互干涉的可能。
在本实施例中，拾音组件162可以通过相应的导线组连接骨传导耳机1上的其他相关部件，例如电池组件14或者控制电路组件15，用于将所获取的音频信号传输至相关部件上进行后续的处理。棍咪组件16的导线组可以穿过弹性连接杆161的棍咪弹性覆层1613，并经接插部1612引出。棍咪组件16的导线组可以经接插部1612穿出后进入到第一扬声器壳体111内。在一些实施例中，棍咪组件16的导线组可以穿入第一通孔1110，并经收容空间110穿至第二通孔1111内。棍咪组件16的导线组可以进一步从第二通孔1111依次穿经耳挂组件12进入到容纳空间120内，电性连接电池组件14或者控制电路组件15。
在实际的使用中，棍咪组件16能够相对于第一扬声器壳体111转动，会使得棍咪组件16的导线组移动，如此可能会由于导线组的不当移动而限制棍咪组件16的转动，而且导线组也可能会将扬声器组件11的振动传递到拾音组件162，进而影响拾音组件162的拾音效果，而且还可能影响电连接稳定性，为此， 本申请发明人提出下述方案，以改善上述技术问题。
图7是根据本申请一些实施例所示的骨传导耳机中扬声器组件的结构另一爆炸示意图。在一些实施例中，如图7所示，扬声器组件11可以包括压持件115，用于压持棍咪组件16的导线组。具体地，压持件115可以设置于收容空间110内且覆盖第一通孔1110，以用于压持经第一通孔1110穿引至第二通孔1111的棍咪组件16的导线组。如此，可以限制棍咪组件16的导线组的活动空间，减少导线组的晃动或者移动，进而能够减少由于扬声器组件11的振动而产生的振动和传递到拾音组件162的振动，提到拾音组件162的拾音效果，也能够提升电性稳定性，此外，压持件115的压持也可以减少导线组和第一扬声器壳体111的摩擦，进而可以保护导线组。收容空间110是第一扬声器壳体111和第二扬声器壳体112配合连接之后所形成的，在图7中将收容空间110标注在第一扬声器壳体111处，仅是为了便于理解和说明。此外，由于转动件114插置于第一通孔1110内，第一通孔1110被转动件114占据，因此，在图7中将第一通孔1110标注在转动件114处，也是为了便于理解和说明。
在一些实施例中，压持件115可以包括层叠设置的硬质盖板1151和弹性体1152。硬质盖板1151相较于弹性体1152远离第一通孔1110，弹性体1152用于接触棍咪组件16的导线组，硬质盖板1151的硬度大于弹性体1152的硬度。硬质盖板1151通过压持弹性体1152接触导线组，由于硬质盖板1151的硬度比弹性体1152的硬度大，硬度较大的硬质盖板1151可以保证了压持导线组的刚度，而硬度较小的弹性体1152可以提高对导线组移动或者振动的吸收，减少导线组的振动，起到缓冲和保护的作用。
具体地，第一扬声器壳体111在第一通孔1110的外围设置有往收容空间110内凸出的多个凸柱1117。多个凸柱1117可以间隔设置于第一通孔1110的外围。硬质盖板1151可以固定于多个凸柱1117，弹性体1152可以设置于多个凸柱1117之间。例如，凸柱1117的数量为三个。通过设置于第一通孔1110外围的多个凸柱1117固定硬质盖板1151，进而将弹性体1152压持棍咪组件16的 导线组，可以提高硬质盖板1151的稳定性，进而可以提高弹性体1152跟导线组接触的稳定性。
可选地，硬质盖板1151为钢片，弹性体1152为泡棉。硬质盖板1151也可以是其他材料，比如塑料、陶瓷等，弹性体1152也可以是其他材料、比如硅胶、纤维等。
基于上述描述，通过设置压持件115压持棍咪组件16的导线组，可以减少导线组由于扬声器组件11的振动而产生的振动，也可以增强棍咪组件16在转动过程导线组的稳定性，也能够保护棍咪组件16的导线组。此外，棍咪组件16的转动也需要具备良好的稳定性，也即转动件114和第一通孔1110的配合结构对棍咪组件16的转动稳定性起到较大作用。
图8是根据本申请一些实施例所示的骨传导耳机中耳挂组件的结构一爆炸示意图，图9是根据本申请一些实施例所示的骨传导耳机中耳挂组件的结构另一爆炸示意图。
在一些实施例中，如图8和图9所示，耳挂组件12可以包括第一耳挂壳体121、连接部件122以及第二耳挂壳体123。连接部件122的一端可以连接第一耳挂壳体121。连接部件122的另一端连接扬声器113。例如，连接部件122的另一端插置于第一扬声器壳体111的第二通孔1111内，以和扬声器组件11接插配合。第一耳挂壳体121和第二耳挂壳体123可以配合连接，以形成收容电池组件14或者控制电路组件15的容纳空间120。在本实施例中，其中一个耳挂组件12的容纳空间120用于收容电池组件14，如图8所示的耳挂组件12。另一个耳挂组件12的容纳空间120用于收容控制电路组件15，如图9所示的耳挂组件12。
在一些实施例中，如图8所示，电池组件14可以包括电池壳体(未标注)和设置于电池壳体内的电芯(图未示)，电芯用于存储电量。上述本申请耳机通信系统实施例中所提及的第一NFC模块102可以贴设于电池组件14上，例如贴设于电池壳体上，如此可以减小骨传导耳机1的体积，也减少第一NFC模块 102与控制电路组件15之间的电磁干扰或者信号干扰等情况。
在一些实施例中，如图9所示，控制电路组件15可以包括电路板151、电源接口152、按键153、天线154等。如图2所示的第一蓝牙模块101可以集成于控制电路组件15。控制电路组件15还可以集成有其他的电路以及元件。例如，第一蓝牙模块101可以集成于电路板151上。传感器组件17也可以集成于电路板151上。
在一些实施例中，如图9所示，以传感器组件17包括光学传感器为例，第一耳挂壳体121可以形成用于透射光学传感器的光信号的窗口1200。窗口1200可以邻近连接部件122设置，以使得骨传导耳机1在被佩戴时窗口1200贴近使用者的邻近耳朵根部的位置。此外，在一些实施例中，窗口还可以设置在后挂组件13或其他位置。在一些实施例中，若传感器组件17为加速度传感器时，还可以将其设置在容纳空间120内。
在一些实施例中，窗口1200呈跑道形设置，需要说明的是，在一些其他实施例中，根据传感器组件17的形式，窗口1200的形状和样式还可根据实际情况进行调整，如为了避免传感器被污染或水气、灰尘进入骨传导耳机1中，传感器组件17为光学类传感器时，可以在窗口1200上设置玻璃等结构。另一个示例，当传感器组件17为接触传感器时，窗口1200可以根据接触部的形状设置为其他形状。
可选地，连接部件122的中轴线的延长线和窗口1200的长轴相交，如图9中示意性示出大致的相交关系。通过设置连接部件122的中轴线的延长线和窗口1200的长轴相交，可以使得窗口1200能够有效地贴近使用者邻近耳朵根部的位置，进而可以保证传感器组件7的灵敏性和检测的有效性。具体地，用于容纳控制电路组件15的耳挂组件12的第一耳挂壳体121可以形成上述窗口1200。
骨传导耳机1的发展趋势会朝向轻便化、体积小型化，而耳挂组件12用于容纳电池组件14或者控制电路组件15以及相关的走线等，往往是骨传导耳机1体积较大的地方，而耳挂组件12中的相关扣位、卡扣结构的设计会影响整 个耳挂组件12的体积。为了减少耳挂组件12的体积，本实施例提供了如下耳挂组件的壳体结构。
在一些实施例中，骨传导耳机1可以包括两个扬声器组件11和两个耳挂组件12，每个扬声器组件11和两个耳挂组件12单独组成用于佩戴的耳机左耳和耳机右耳，具体的，电池组件14和控制电路组件15可以分别设置于两个耳挂组件围成的容纳空间120内。在一些实施例中，如图2中所述，两个第一蓝牙模块101可以分别设于两容纳空间120内，并通过TWS建立连接。需要说明的是，在上述实施例中，可以通过耳挂组件保持与用户耳部的固定，因此可以无需耳挂组件12，此外，骨传导耳机1还可以包括耳挂组件12，但由于两个第一蓝牙模块101通过TWS连接，因此耳挂组件内无需走线。
图10是根据本申请一些实施例所示的骨传导耳机中第一耳挂壳体和第二耳挂壳体的一结构示意图，图11是根据本申请一些实施例所示的骨传导耳机中第一耳挂壳体和第二耳挂壳体的另一结构示意图，图12是图3中以B-B为剖切线的截面结构示意图。
在一些实施例中，如图10所示，第一耳挂壳体121可以形成有间隔设置的第一卡槽1211和第二卡槽1212，第二耳挂壳体123可以形成有间隔设置的第一卡块1231和第二卡块1232，第一卡槽1211和第一卡块1231可以卡接配合，第二卡槽1212和第二卡块1232卡接配合，进而使得第一耳挂壳体121和第二耳挂壳体123可以卡接配合。
在一些实施例中，容纳空间120可以具有相互垂直的长度方向和厚度方向。本实施例下述内容，若无特殊注明，长度方向均指容纳空间120的长度方向，厚度方向均指容纳空间120的厚度方向。
如图10和图11所示，第一耳挂壳体121和第二耳挂壳体123沿垂直于长度方向和厚度方向的拼接方向彼此拼接，进而形成容纳空间120。例如，第一耳挂壳体121具有第一子容纳空间1210，第二耳挂壳体123具有第二子容纳空间1230，第一耳挂壳体121和第二耳挂壳体123拼接后，第一子容纳空间1210 和第二子容纳空间1230组合成容纳空间120。
在一些实施例中，第一耳挂壳体121沿长度方向间隔可以形成有开口方向相同的第一卡槽1211和第二卡槽1212。也即，第一卡槽1211和第二卡槽1212的开口所朝向的方向是相同的。第二耳挂壳体123沿长度方向凸出设置有延伸方向相同的第一卡块1231和第二卡块1232。也即，第一卡块1231和第二卡块1232在长度方向上间隔设置，且两者的凸出方向相同，进而两者朝向同一方向，可以使得第一卡块1231和第二卡块1232可以沿同一方向分别嵌入到第一卡槽1211和第二卡槽1212内。
在一些实施例中，如图12所示，第一卡块1231可以嵌入第一卡槽1211内，第二卡块1232可以嵌入第二卡槽1212内，以限制第一耳挂壳体121和第二耳挂壳体123在拼接方向和厚度方向上的相对移动。
在一些实施例中，第一耳挂壳体121的拼接边缘1201和第二耳挂壳体123的拼接边缘1202可以彼此契合，以限制第一耳挂壳体121和第二耳挂壳体123在长度方向相对移动。在本实施例中，第一耳挂壳体121和第二耳挂壳体123拼接可以是指第一耳挂壳体121的拼接边缘1201和第二耳挂壳体123的拼接边缘1202大致上接触且连接。其中，第一耳挂壳体121的拼接边缘1201可以是指第一耳挂壳体121朝向第二耳挂壳体123一侧的边缘，用于和第二耳挂壳体123进行拼接，如图10所示的拼接边缘1201。同理，第二耳挂壳体123的拼接边缘1202可以是指第二耳挂壳体123朝向第一耳挂壳体121一侧的边缘，用于和第一耳挂壳体121进行拼接，如图11所示的拼接边缘1202。例如，第一耳挂壳体121的拼接边缘1201和第二耳挂壳体123的拼接边缘1202的形状相适应，两者能够契合或者互补，进而形成一个稳定的配合结构，可以限制两者在长度方向上的相对移动。
在一些实施例中，对于第一卡块1231和第二卡块1232的延伸方向相反而言，第一卡块1231和第二卡块1232分别向相反的方向凸出，必然会导致第一卡块1231和第二卡块1232额外占用的空间增大，第一卡槽1211和第二卡槽 1212为了能够使得第一卡块1231和第二卡块1232能够嵌入，也需要在长度方向上增大距离，以能够罩住第一卡块1231和第二卡块1232，而本实施例通过设置开口方向相同的第一卡槽1211和第二卡槽1212以及延伸方向相同的第一卡块1231和第二卡块1232，如此可以使得第一卡块1231和第二卡块1232与第一卡槽1211和第二卡槽1212的配合方向是相同的，由于第一卡块1231和第二卡块1232的延伸方向相同，可以减少第一卡块1231和第二卡块1232所额外占用的体积，进而可以减小第一卡块1231和第二卡块1232和第一卡槽1211和第二卡槽1212配合的所占据的体积，如此可以有效地减小耳挂组件12的体积，此外，利用第一耳挂壳体121的拼接边缘1201和第二耳挂壳体123的拼接边缘1202彼此契合，可以无需设置额外的卡扣、凸起等结构，如此使得耳挂组件12结构更紧凑且也可以减小耳挂组件12的体积。同时，通过第一卡块1231和第二卡块1232与第一卡槽1211和第二卡槽1212的配合能够限制拼接方向和厚度方向的位移，通过拼接边缘1201、1202的契合能够限制长度方向的位移，如此能够使得第一耳挂壳体121和第二耳挂壳体123的拼接更稳定，结构更可靠。
在一些实施例中，如图10所示，第一卡槽1211和第二卡槽1212可以分别位于第一耳挂壳体121沿长度方向上的两侧，第一卡槽1211的开口方向朝向容纳空间120，第二卡槽1212的开口方向背离容纳空间120。也即，第一卡槽1211的开口方向朝向第一子容纳空间1210，第二卡槽1212的开口方向背离第一子容纳空间1210。可选地，第一卡槽1211开设于第一耳挂壳体121靠近连接部件122的一侧，第二卡槽1212开设于第一耳挂壳体121远离连接部件122的一侧。
在一些实施例中，如图11所示，第一卡块1231和第二卡块1232可以分别位于第二耳挂壳体123沿长度方向上的两侧，第一卡块1231的延伸方向背离第一卡槽1211，第二卡块1232的延伸方向朝向第一卡槽1211内。也即，第一卡块1231的延伸方向背离第二子容纳空间1230，第二卡块1232的延伸方向朝向第二子容纳空间1230。相应地，第一卡块1231设置于第二耳挂壳体123靠近 连接部件122的一侧，第二卡块1232设置于第二耳挂壳体123远离连接部件122的一侧。由于第二卡块1232向容纳空间120内凸出延伸，相对于向容纳空间120外凸出延伸而言，不需要占据额外的空间，能够节省了相应的空间，第二卡槽1212在配合时位于第二卡块1232延伸方向的前方，两者嵌入配合，也能够减小耳挂组件12的体积。
在一些实施例中，第一耳挂壳体121的拼接边缘1201设置有第一止挡部1213，第二耳挂壳体123的拼接边缘1202设置有第二止挡部1234，第一止挡部1213和第二止挡部1234彼此契合，以限制第一耳挂壳体121和第二耳挂壳体123在长度方向上的相对移动。例如，第一止挡部1213为第一耳挂壳体121的拼接边缘1201所形成的开口部，第二止挡部1234为第二耳挂壳体123的拼接边缘1202形成的凸出部，开口部和凸出部的外形相适应，能够彼此契合，进而使得第一耳挂壳体121的拼接边缘1201和第二耳挂壳体123的拼接边缘1202可以互补，以限制两者在长度方向的相对移动。
第一卡槽1211的开口方向朝向容纳空间120的，如果直接第一子容纳空间1210内形成第一卡槽1211，在利用相应模具形成第一子容纳空间1210和第一卡槽1211的过程中，形成第一子容纳空间1210的拔模方向和形成第一卡槽1211的拔模方向可能相互干扰，由于的第一卡槽1211的拔模方向是在第一子容纳空间1210内，还可以与其他结构的拔模方向产生冲突，给生产上带来较大的困难。
图13是根据本申请一些实施例所示的骨传导耳机中第一耳挂壳体和第二耳挂壳体的又一结构示意图。在一些实施例中，如图13所示，第一耳挂壳体121可以开设有从容纳空间120外到容纳空间120内的方向上彼此连通的外侧孔段1215和内侧孔段1216。也即，外侧孔段1215的开口方向背向容纳空间120，内侧孔段1216的开口方向朝向容纳空间120，外侧孔段1215和内侧孔段1216连通。外侧孔段1215内填设有填充件1217。填充件1217例如是橡胶件，例如是硬胶。外侧孔段1215被填充封堵后，内侧孔段1216就可以作为第一卡槽1211， 内侧孔段1216的开口方向朝向容纳空间120，可以和第一卡块1231进行配合。
在实际的制造过程中，可以从第一耳挂壳体121外到第一耳挂壳体121内，依次形成有外侧孔段1215和内侧孔段1216，拔模方向不在第一子容纳空间1210内进行，而是在第一耳挂壳体121外，接着再使用填充件1217填充外侧孔段1215，使得剩下的内侧孔段1216可以作为第一卡槽1211，如此有效地减低制造难度和制造的复杂性，节省成本。
在一些实施例中，外侧孔段1215垂直于外侧孔段1215和内侧孔段1216的连通方向的横截面积大于内侧孔段1216垂直于外侧孔段1215和内侧孔段1216的连通方向的横截面积。由于外侧孔段1215相应的横截面积大于内侧孔段1216相应的横截面积，可以便于在外侧孔段1215内填设填充件1217，进而可以具有更好的封堵效果，进而更快速地形成第一卡槽1211。
在一些实施例中，如图10至图12所示，第二耳挂壳体123远离连接部件122的部分壳体开设有电源插孔1233。电源插孔1233连通容纳空间120，电源插孔1233用于容纳电源接口152。例如，第二耳挂壳体123也可以具有壳体底部和壳体侧部，壳体侧部环绕连接壳体底部，以形成第二子容纳空间1230。壳体侧部远离壳体底部的一侧边缘则作为与第一耳挂壳体121进行拼接的拼接边缘1202。电源插孔1233开设于壳体侧部，连通第二子容纳空间1230，也即连通容纳空间120。
在一些实施例中，如图12所示，第二卡块1232邻近电源插孔1233设置。也即，第二卡块1232凸出设置于第二耳挂壳体123远离连接部件122的部分壳体，且朝向容纳空间120内。在本实施例中，第二卡块1232相较于电源插孔1233更靠近容纳空间120。可以换言之，第二卡块1232相较于电源插孔1233更靠近连接部件122。
在一些实施例中，第二卡块1232和电源插孔1233在垂直于长度方向的第一基准面上的投影彼此重叠。在本实施例中，彼此重叠包括部分重叠(也即，重叠的部分是第二卡块1232投影的一部分，也是电源插孔1233投影的一部分)， 也包括全部重叠(也即第二卡块1232的投影完全落入到电源插孔1233的投影内)。可选地，以垂直于长度方向的平面作为第一基准面，第二卡块1232在第一基准面上的投影位于电源插孔1233在第一基准面上的投影内，也即两者的投影范围全部重叠。如此设置第二卡块1232和电源插孔1233的位置，可以在不影响电源接口152的安装的情况下使得第二耳挂壳体123的结构紧凑，减小耳挂组件12的体积。
在一些实施例中，第二卡块1232和电源插孔1233在垂直于拼接方向的第二基准面上的投影彼此重叠。此处的彼此重叠也同样是包括部分重叠，也包括全部重叠。可选地，以垂直于拼接方向的平面作为第二基准面，第二卡块1232在第二基准面上的投影也位于电源插孔1233在第二基准面上的投影内，也即两者的投影范围也全部重叠。如此可以使得第二卡块1232和电源插孔1233无论是在拼接方向还是长度方向上结构安排都比较紧凑，能够较大化地节省电源插孔1233和第二卡块1232所占用的空间，以提升耳挂组件12的结构紧凑性。
此外，在工业等生产制造领域使用骨传导耳机1，对于骨传导耳机1的操控体验有极大的要求，将电源插孔1233开设于第二耳挂壳体123远离连接部件122的部分壳体可以提高骨传导耳机1的操作体验，原因如下：
骨传导耳机1一般会具有音量按键等，按照现有的常规手段，按键153等对应的按键孔1235和电源插孔1233一般会开设第二耳挂壳体123的壳体底部，也即第二耳挂壳体123远离第一耳挂壳体121的部分壳体。由于壳体底部的面积比较受限，因此按键孔1235和电源插孔1233之间比较紧凑，按键孔1235和电源插孔1233尽可能不多占地方。在工业等生产制造领域，佩戴者可能穿着工作服或者手套等，按键孔1235较小，排列太紧凑，会导致佩戴者的操控体验下降，极容易导致误操控。而本实施例不在壳体底部上开设电源插孔1233，而是在壳体侧部上开设电源插孔1233，那么按键孔1235的大小可以设计得较大，相互之间排列可以较为宽松，如此可以便于使用者进行操作，减少误操控的发生。
此外，基于上述电源插孔1233的设计，如果将第二卡块1232设置于第 二耳挂壳体123邻近电源插孔1233且朝向第一耳挂壳体121的顶部位置(如图11所示的连接第二卡块1232的平台区域，也即第二卡块1232可以视为从该平台区域往第二子容纳空间1230内延伸形成的)，会挤压第一耳挂壳体121的接插孔1218的空间，进而会影响到耳挂组件12和后挂组件13之间的接插配合，第二卡块1232需要占据额外的空间，会使得第一耳挂壳体121和第二耳挂壳体123在拼接方向上的拼接占据较大的空间，不够紧凑，因此，本实施例通过将电源插孔1233设置于第二耳挂壳体123的壳体底部，以及以上述投影关系设置第二卡块1232和电源插孔1233之间结构关系，使得第二耳挂壳体123在拼接方向上结构更紧凑，第二卡块1232朝向容纳空间120内延伸，可以不用占据额外的空间，进而可以将耳挂壳体12的体积小型化。
基于上述详细描述，第一耳挂壳体121和第二耳挂壳体123之间稳定的拼接结构可以保护容纳空间120内的电池组件14和控制电路组件15。当然，为了能够减少骨传导耳机1的故障率，不仅需要保证结构的稳定性，也需要保证电气连接的稳定性。骨传导耳机1内到导线组在扬声器组件11、耳挂组件12之间走线，走线的稳定性关系到骨传导组件的可靠性。为了提高走线的可靠性，耳挂组件12可以设置相应的卡线结构，以在导线组穿过耳挂组件12时保证导线的稳定，具体可以参见如下描述。
在一些实施例中，连接部件122可以包括耳挂弹性金属丝1221和连接于耳挂弹性金属丝1221一端的接头部1222。为了保护耳挂弹性金属丝1221，连接部件122也可以包括至少包覆于耳挂弹性金属丝1221的外周的耳挂弹性覆层1223(如图10所示)。当然，耳挂弹性金属丝1221还可以进一步包覆第一耳挂壳体121。接头部1222用于与扬声器组件11进行接插配合。耳挂弹性金属丝1221的另一端连接第一耳挂壳体121。
图14是根据本申请一些实施例所示的骨传导耳机中后挂组件的结构爆炸示意图，图15是根据本申请一些实施例所示的骨传导耳机中耳挂组件的结构示意图。
在一些实施例中，如图14所示，后挂组件13可以包括后挂弹性金属丝131、包覆在后挂弹性金属丝131上的后挂弹性覆层132以及设置于后挂弹性金属丝131两端的插置部133。后挂弹性覆层132还可以包覆至少部分插置部133。
在一些实施例中，插置部133用于与耳挂组件12接插配合。具体地，第一耳挂壳体121远离连接部件122的一侧开设有连通容纳空间120的接插孔1218。接插孔1218和第二卡槽1212相邻设置。插置部133可以和接插孔1218接插配合。至少一个插置部133在其长度方向上间隔开设有两组开槽1331。也即，至少一个插置部133在插置部133的长度方向上间隔开设有两组开槽1331，每组开槽1331包括至少一个开槽1331。后挂弹性金属丝131经插置部133的一端插置于插置部133内。一组开槽1331邻近插置部133，另一组开槽1331远离插置部133的一端。
在一些实施例中，插置部133从插置部133的一端到插置部133的另一端的方向上，依次开设有上述两组开槽1331。靠近插置部133的一端的开槽1331用于进行模具定位。远离插置部133的一端的开槽1331用于与第一耳挂壳体121进行卡接配合。
例如，两组开槽1331分为第一组开槽1331和第二组开槽1331，第一组开槽1331远离插置部133的一端，并用于和耳挂组件12进行卡接配合。如图14和18所示，第一耳挂壳体121凸出设置有卡接部12181。例如，第一耳挂壳体121的接插孔1218内凸出设置有卡接部12181。插置部133插接于接插孔1218内且卡接部12181嵌入第一组开槽1331内，进而限制耳挂组件12和后挂组件13的相对移动。
第二开槽1331靠近插置部133的一端，并用于进行模具定位。也即，第二组开槽1331用于和模具上相应的凸出结构进行配合，进而将插置部133精确地固定于某个位置，进而能够对其进行其他的工序，提升良品率。例如利用第二组开槽1331对插置部133和后挂弹性金属丝131进行定位，进而可以通过注塑方式形成后挂弹性覆层132。
可选地，开槽1331自插置部133位于其中轴线两侧的边缘往中轴线方向延伸设置。每组开槽1331包括两个开槽1331，每组的两个开槽1331相背设置。
