Description

骨传导发声装置 【技术领域】
本申请涉及耳机技术领域，特别是涉及一种骨传导发声装置。
【背景技术】
通常，声音会通过两种传递途径传递入耳朵，即气传导和骨传导，进而产生听觉。
在骨传导途径中，骨传导振动扬声器能将音频电信号转换成机械振动信号，并将振动信号通过生物体组织及骨头传导入耳蜗，使使用者听到声音。相对于通过振膜产生声波的经典声音传导方式，骨传导省去了许多声波传递的步骤，能在嘈杂的环境中实现清晰的声音还原，而且声波也不会因为在空气中扩散而影响到他人。
然而，本申请的发明人在长期的研发过程中发现，当前常见的骨传导发声装置中，通常是将骨传导扬声器贴合至乳突(如骨传导助听器)、耳屏前端(如骨传导立体声耳机)、头骨其他位置(如骨传导通讯头盔)等，上述的骨传导传递路径均是声音/振动经过皮肤及皮下软组织后传递到硬质骨上，进而传导至耳蜗产生骨传导听觉，这样会缩小骨传导声音/振动的频宽，使得音质变差，听音体验不佳。
【发明内容】
本申请主要解决的技术问题是如何能够改善骨传导发声装置的音质。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种骨传导发声装置，该骨传导发声装置包括：骨传导扬声机构；固定机构，该固定机构作用于骨传导扬声机构，使得至少在骨传导扬声机构处于使用状态时，将该骨传导扬声机构贴合于用户的耳廓背面。
本申请的有益效果是：区别于现有技术的情况，本申请骨传导发声装置，在用户使用时，能够将发声机构贴合于用户的耳廓背面，从而能够利用耳廓的耳软骨传递骨传导声音/振动，由于耳软骨的刚度较小，对低频声音/振动的传递效率较高，能够减少低频在传递过程中的缺失；且耳廓本身及其相连组织也会产生相应振动，产生相应空气传导声，进一步补偿骨传导声音/振动在传递过程中的低频缺失和由皮肤及皮下软组织造成的高频缺失，从而能够改善骨传导发声装置的音质。

【具体实施方式】
在阐述本申请各实施方式之前，先对相关的现有技术进行简单介绍。
区别于空气传导途径，骨传导途径传递声音/振动的介质为固体或固液混合体，传递路径的特性对骨传导音质有显著影响，因此，选择合适的骨传导传递路径，调节和控制传递路径的特性为改善骨传导音质的重要手段。
常见的方案是将骨传导扬声器贴合至乳突(如骨传导助听器)、耳屏前端(如骨传导立体声耳机)、头骨其他位置(如骨传导通讯头盔)等，上述的骨传导传递路径均是声音/振动经过皮肤及皮下软组织后传递到硬质骨上，进而传导至耳蜗产生骨传导听觉，具体传递路径请参阅图1。这种传递途径会对骨传导音质带来如下两方面的主要影响：(1)皮肤及皮下软组织有较大机械阻尼，其对高频声音/振动的传递效率较低，使得骨传导声音的高频变弱或缺失；(2)传递路径上的硬质骨有较大的刚度，其对低频声音/振动的传递效率较低，使得骨传导声音的低频变弱或缺失。
另外，利用数学计算的方法可以计算出皮肤及皮下组织、硬质骨的刚度对传递路径的频域特性的影响。首先，请参阅图2，由图2可以看出，皮肤及皮下组织的作用，使得传递路径的幅频曲线在中高频段有明显下降，表明了皮肤及皮下组织对骨传导声音中对高频具有削弱作用。另外，请参阅图3，硬质骨的刚度的改变，使得传递路径的幅频曲线在全频段均产生变化。特别地，其能显著影响中低频的传递特性，将硬质骨的刚度提高，中低频的幅频曲线下降，表明了硬质骨刚度对骨传导声音中中低频具有削弱作用。
也就是说，上述两个因素会导致缩小骨传导声音/振动的频宽，进而使得音质变差，听音体验不佳。
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清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性的劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参阅图4，图4是本申请骨传导发声装置一实施方式的结构示意图。
需要指出的是，本申请实施方式中的骨传导发声装置可以是具有骨传导的耳机功能的各种设备，例如既可以是骨传导耳机，还可以是具有骨传导发声功能的眼镜、帽子、头饰、 或者其它头戴工程用品、头戴军工用品、或者助听器等助听装置，此处不做具体限定。
其中，该骨传导发声装置包括：固定机构10和骨传导扬声机构20。其中，固定机构10作用于骨传导扬声机构20，使得至少在骨传导扬声机构20处于使用状态时，将骨传导扬声机构20贴合于用户的耳廓背面。
需要指出的是，耳廓为外耳的一部分，主要由软骨构成。本实施方式中，将骨传导扬声机构20贴合至耳廓背面，进而可利用耳廓的软骨传递骨传导声音/振动。
由于相对于硬质骨，耳软骨的刚度较小，其对低频声音/振动的传递效率较高，能较好地传递低频，减少低频在传递过程中的缺失；并且由于耳廓呈扇形，在传递骨传导声音/振动的过程中，耳廓本身及其相连组织也会产生相应振动，进而产生相应空气传导声；同时，在耳道内，耳廓振动引起的耳道壁面震动使得耳道内的气声产生高频谐振。这些空气传导声能进一步补偿骨传导声音/振动在传递过程中的低频缺失和由皮肤及皮下软组织造成的高频缺失。具体地，当骨传导扬声器贴合耳廓时，骨传导声音/振动的传递路径如图5所示，也就是说，在传递路径中增加了耳廓软骨传递的环节。
另外，请进一步参阅图6，利用数学计算的方法可以计算出骨传导扬声机构20贴合耳廓背面的方案与相关现有技术中的贴合方案传递路径的频域特性。相对于现有技术中的贴合方案，由于传递路径中增加了耳廓软骨环节，使得传递路径的幅频曲线在中低频有明显提升，这进一步表明了本实施方式中将骨传导扬声机构20与用户耳廓背面贴合能够减小传递过程中的低频损失。
进一步地，将骨传导扬声机构20在耳廓背面贴合，在提高音质的同时，还能够减小声音传递过程中对耳道的影响，同时，由于骨传导扬声机构20贴合在耳廓背面，进而使得骨传导扬声机构20能够隐藏在耳后而不显现出来以满足用户的不同需求。
可选地，固定机构10作用于骨传导扬声机构20，使骨传导扬声机构20贴合于用户的耳廓背面的预定区域。进一步地，由于耳轮脚正对的耳廓背面区域较为平坦，适合骨传导扬声机构20以较大面积贴合，以获得更高的振动传递效率以及更大音量；此外，该区域内的软骨层较厚，更贴近内耳道，韧性更强，在获得较好音质的同时，能够避免通过耳廓边缘传振造成的振动、麻痒等不适感受，因此，可以以耳轮脚正对的耳廓背面的区域作为预定区域，具体请参阅图7和图8。具体地，预定区域可以为以耳轮脚位置正对的耳廓背面位置为中心面积为20cm 2的区域；还可以是以耳轮脚位置正对的耳廓背面位置为中心面积为10cm 2的区域，即耳廓背面除去耳轮的部分；或者还可以是以耳轮脚位置正对的耳廓背面位置为中心面积为5cm 2的区域，即耳甲腔对应的耳廓背面的区域。
另外，固定机构10可以是专门用于固定骨传导发声装置的机构，在用户需要使用骨传导发声装置时，将该固定机构10固定在用户耳朵附近，以使得骨传导扬声机构20贴合在耳廓背面；或者，固定机构10也可以是与骨传导扬声机构20连接的具有独立功能的其它设备，在用户佩戴该设备时，可以直接或者通过一定的手段间接将骨传导扬声机构20贴合于用户的耳廓背面，从而在用户使用该物件的其它功能的同时，还可以使用骨传导发声装置的功能。
请继续参阅图4，在一个应用场景中，固定机构10为眼镜架30，眼镜架30包括眼镜框31以及眼镜腿32，眼镜腿32包括与眼镜框31连接的镜腿主体321以及与镜腿主体321远离眼镜框31的端部通过铰链40进行铰接的连接件322。骨传导扬声机构20进一步设置于连接件322上。
其中，本应用场景中的眼镜架30可以是近视镜、远视镜、太阳镜、3D眼镜、智能眼镜、虚拟现实眼镜、全息眼镜、增强现实眼镜、等各种眼镜的眼镜架，具体不做限定。
可选地，连接件322设置成使得骨传导扬声机构20相对于镜腿主体321能够在第一相对固定位置和第二相对固定位置之间进行切换，并在骨传导扬声机构20处于第一相对固定位置时能够贴合于用户的耳廓背面。具体地，骨传导扬声机构20相对于镜腿主体321的第一相对固定位置如图9中所示，骨传导扬声机构20相对于镜腿主体321的第二相对 固定位置如图4中所示。需要指出的是，本应用场景中骨传导扬声机构20在相对于镜腿主体321处于其中一个相对固定位置时，需要通过向铰链40施加预设大小的力才能够将骨传导扬声机构20切换至另一相对固定位置，而不会因为骨传导扬声机构20的自身重力等原因导致骨传导扬声机构20的相对固定位置的自动改变，从而能够使得用户能够准确得定位骨传导扬声机构20的位置。
在一个具体的应用场景中，骨传导扬声机构20相对于镜腿主体321仅具有第一相对固定位置和第二相对固定位置，而无中间过渡状态。例如在骨传导扬声机构20相对于镜腿主体321处于如图4中的第二相对固定位置时，该骨传导眼镜可作为正常的眼镜使用，此时，用户可手动向铰链40施加大于预设大小的力扳动连接件322，连接件322和骨传导扬声机构20相对于镜腿主体321发生折叠而使得骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置，使骨传导扬声机构20的贴合面21贴合用户的耳廓背面，从而使得用户能够同时使用该骨传导眼镜的眼镜功能和耳机功能，而不会出现介于第一相对固定位置和第二相对固定位置之间的其它位置。
当然，在其它应用场景中，骨传导扬声机构20相对于镜腿主体321还可具有上述第一相对固定位置和第二相对固定位置之外的一个或多个其它相对固定位置，以满足用户的不同使用需求。
可选地，骨传导扬声机构20包括贴合面21，用于在骨传导扬声机构20处于使用状态时，贴合于用户的耳廓背面，进而实现声音/振动通过耳廓背面进行传递。
其中，贴合面21至少部分为曲面，例如可以包括朝向耳廓背面凸起的弧面，这使得骨传导扬声机构20与形状不规则的耳廓背面能够良好贴合。具体地，贴合面21还可以包括凸起的且曲率不大于1的弧面，使得骨传导扬声机构20与耳廓背面能够进一步充分接触，从而提高骨传导扬声机构20通过耳廓背面进行声音/振动的传递的效率。
另外，请参阅图10，在一个应用场景中，贴合面21包括位于中部的平面21a，以及沿平面周向延伸的曲面21b，该平面21a和曲面21b共同构成朝向耳廓背面凸起的弧面。
可选地，贴合面21的面积不小于0.5cm 2，或不小于1cm 2。由于本实施方式中贴合面21面积足够大，能够进一步使得骨传导扬声机构20与耳廓背面的接触面积足够大，从而一方面能够减小骨传导扬声机构20的贴合面21对用户耳廓背面的压强，提升用户佩戴该骨传导发声装置的舒适度；另一方面能够提高骨传导声音/振动的传递效率，且使得声音的音量足够大，以满足用户的使用需求。
在一个应用场景中，如图4所示，连接件322可以为与耳廓匹配的凹弧形，且凹处朝向用户耳朵前部，使得在用户使用骨传导发声装置时，连接件322能够环绕用户的耳廓背面设置。
其中，连接件322可以为具有弹性的柔性连接杆，该柔性连接杆可以是橡胶材质，或橡胶和弹性金属丝的复合结构，例如可以是橡胶与钛丝或钛合金丝的复合结构，或者橡胶与记忆合金丝的复合结构。
在用户佩戴该骨传导发声装置且至少在骨传导发声装置处于使用状态时，在眼镜架30支持下，连接件322能够施加弹力至骨传导扬声机构20，使该骨传导扬声机构20以预定压力贴合于用户的耳廓背面。
其中，预定压力是指在用户使用正常佩戴骨传导发声装置时，贴合面21在垂直贴合面21方向上贴合用户耳朵的压力。连接件322的不同弹性系数的材料、以及连接件322的不同形状、规格等，均会影响骨传导扬声机构20对用户的耳廓背面施加的预定压力的大小。具体可以通过测试得出贴合面21对用户耳廓背面的压力大小，具体地，请参阅图11，在用户正常使用的状态下，骨传导扬声机构20的贴合面21与耳廓背面贴合良好。镜腿主体321与连接件322连接的中心点为固定点将铰链40固定，使用测力装置沿与贴合面21垂直的方向将骨传导扬声机构20拉离耳廓背面。取骨传导扬声机构20恰与耳廓背面分离时所测得的力作为骨传导扬声机构20对用户的耳廓背面施加的压力，然后根据测 得的压力值，进一步确定合适的连接件322的材料以及形状、规格等，以调节对应的压力于合适的范围之内。
当然，预定压力并不一定为固定值，例如用户在佩戴骨传导发声装置时，不同的佩戴状态，以及不同的头型的人佩戴，其所对应的预设压力的值是不同的。此时，由于连接件322为柔性连接杆，从而能够根据不同的头型等进行不同程度的变形，以适应不同的情况。
具体地，预定压力的上限可以为1N，该压力上限能够使得骨传导扬声机构20不会因压力过大而产生较大变形造成使用者产生痛觉等其他不适感；下限可以为0.1N，以使得骨传导扬声机构20在工作时贴合面21始终与耳廓背面贴合，不会出现因骨传导扬声器振动造成骨传导扬声机构20与耳廓背面脱离的情况。
可选地，预定压力的上限还可以为0.8N，能够进一步减小耳廓的变形，确保使用者长时间佩戴不会产生不适；同时下限值还可以为0.3N，使得骨传导扬声机构20能稳固贴合用户耳廓背面的同时，使耳廓背面与骨传导扬声机构20接触的面积因耳廓的适当变形而变大，进而有足够大的接触面积传递骨传导声音/振动，从而使得骨传导发声装置有足够大的音量。
具体地，预定压力的上限及下限还可以为0.1N～1N之间的其他数值，以适应例如欧美人、亚洲人、男性、女性等人群的不同需求，此处不做具体限定。
可选地，铰链40的铰链转轴41的中垂面α、连接件322的对称面β以及骨传导扬声机构20贴合耳朵的贴合面21中心点O同在一个平面内，或在相对平面的预定误差范围内。
其中，铰链转轴41的中垂面α是指垂直于铰链转轴41的轴向且将该铰链转轴41对称分割的面，具体请参阅图12。
连接件322的对称面β是指将连接件322对称分割的面，即在连接件322的对称面β两侧，连接件322呈对称分布，具体请参阅图13。
其中，预定误差范围可以根据经验以及连接件的材料、规格以及耳朵的形状的统计数据等综合得出。
需要指出的是，铰链转轴41的中垂面α、连接件322的对称面β以及骨传导扬声机构20贴合耳朵的贴合面21中心点同在一个平面内时，能够使得与连接件322连接的骨传导扬声机构20能够直接贴合用户的耳廓背面，连接件322受力发生形变时，形变方向、以及骨传导扬声机构20的移动方向一致，且都位于该平面内，而避免在上述各面和点不在同一平面内，且连接件322受力发生弹性形变时，因连接件322及骨传导扬声机构20发生扭转而导致骨传导扬声机构20无法贴合或完全贴合到用户的耳廓背面，从而造成声音/振动传递效率的降低，进而降低骨传导发声装置的音质。当然，铰链转轴41的中垂面α、连接件322的对称面β以及骨传导扬声机构20贴合耳朵的贴合面21中心点可在相对平面的预定误差范围内，这样能够使得在实际使用过程当中，不会对用户使用造成过多影响，但是需要指出的是，此时，会在一定程度上影响骨传导扬声机构20的贴合面21与用户耳廓背面的贴合效果。
可选地，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，由两条镜腿主体321的顶部所定义的水平参考平面γ与连接件322的对称面β之间的夹角为65°～85°。
其中，由两条镜腿主体321的顶部所定义的水平参考平面γ是指与两条镜腿主体321的顶部同时相切的平面，在一个应用场景中，该平面进一步垂直于眼镜框31的对称面，具体如图14所示；连接件322的对称面β与如上述图13中所示相同，此处不再赘述。
容易理解地，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，若由两条镜腿主体321的顶部所定义的水平参考平面γ与连接件322的对称面β之间的夹角较大，则骨传导扬声机构20会较为靠近耳廓背面的外侧，过大时甚至不能贴合到耳廓；而若该夹角较小，则会太靠近耳廓背面的内侧，甚至压迫头部的颅骨，进而一方面会降低用户的舒适度；另一方面，会影响骨传导扬声器通过耳软骨进行声音/振动的传递，进而降 低骨传导扬声机构20的音质。而在该夹角位于65°～85°范围内时，则可以使得骨传导扬声机构20能够贴合在用户耳廓背面较为的适中的位置。
另外，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，由两条镜腿主体321的顶部所定义的水平参考平面γ与连接件322的对称面β之间的夹角还可以为70°～82°，以使得骨传导扬声机构20的贴合面21更进一步靠近耳轮脚位置正对的耳廓背面区域。
具体地，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，由两条镜腿主体321的顶部所定义的水平参考平面γ与连接件322的对称面β之间的夹角可以为上述范围内的任意角度，如70°、75°、80°、82°等均可，此处不做具体限定。
可选地，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，眼镜框31的对称面λ与连接件322的对称面β之间的夹角为5°～30°。
其中，眼镜框31的对称面λ是指将眼镜框31对称分割的对称平面，具体如图15所示。连接件322的对称面β与上述图13中所示相同，此处不再赘述。
其中，上述眼镜框31的对称面λ与连接件322的对称面β之间的夹角与用户的头型有关，例如，欧美人群与亚洲人群对应的该角度是不同的。在用户佩戴时，一方面靠用户的耳朵支撑镜腿主体321的底面，另一方面还需要靠镜腿主体321的侧面抵靠用户的头部的侧面进而将骨传导扬声机构20固定在合适的位置。因此，若该角度较大，镜腿主体321的前部抵靠头部，而后部远离头部；若该角度较大，则镜腿主体321的前部远离头部，而后部抵靠头部，两种情况下，镜腿主体321均不能与头部良好接触，从而容易导致骨传导扬声机构20的贴合面21脱离耳廓背面，从而降低骨传导扬声机构20的音质，且给用户使用带来不便。
其中，在骨传导扬声机构20相对于镜腿主体321处于第一相对固定位置时，眼镜框31的对称面λ与连接件322的对称面β之间的夹角还可以为10°～25°，具体还可以为10°、15°、20°、25°等，此处不做限定。
可选地，请参阅图16，两条眼镜腿32对应的铰链转轴41的中心点之间的距离h 1可以为90～150mm。该距离h 1对应于用户头部的左右宽度。
容易理解地，两条眼镜腿32放置在用户的耳朵上部并夹持在头部两侧，若两条眼镜腿32对应的铰链转轴41的中心点之间的距离h 1较大，则眼镜腿32朝向用户头部的夹持力较小，会出现“夹不紧”的情况，从而导致容易从用户头部松离，进而导致骨传导扬声机构20偏离对应耳廓背面的位置；而若该内收角交小，则眼镜腿32会过于夹紧用户的头部，容易给用户带来不适。
其中，两条眼镜腿32对应的铰链转轴41的中心点之间的距离h 1还可以为100～130mm，具体还可以为100mm、110mm、120mm、130mm等。需要指出的是，不同用户的头型不同，可以选择该距离h 1的范围较为合适的耳机。例如男款的距离h 1可以为115～130mm，女款的范围则可以为100～115mm，当然也可以设置为两个范围的中间值，以同时适应两种人群。
可选地，请继续参阅图16，眼镜框31的对称中心点到两个铰链转轴41的中心点的连线的垂直距离h 2为105～170mm。
需要指出的是，眼镜框31的对称中心点为位于眼镜框31中间的鼻梁的中点位置，该垂直距离对应于用户头部的前后长度。
容易理解地，若该垂直距离h 2较大，则在骨传导扬声机构20的贴合面21能够贴合到耳廓背面时，眼镜框31可能离用户的眼部较远，而在耳机眼镜框31佩戴合适时，则骨传导扬声机构20的贴合面21由于离耳廓背面较远而不能够合适得贴合在耳廓背面；若该距离较小，则在同时使用眼镜功能以及耳机功能时，眼镜框31和骨传导扬声机构20同时在用户头部前后过紧夹持头部，给用户带来不适，或者在距离过小时，甚至难以同时使用两个功能。
其中，眼镜框31的对称中心点到两个铰链转轴41的中心点的连线的垂直距离h 2还可以为130～150mm，具体还可以为130mm、140mm、150mm等。需要指出的是，不同的使用人群，可以对应不同的距离范围，例如，男款的距离h 2可以为140～160mm，女款的范围则可以为或105～135mm，当然也可以设置为两个范围的中间值，以同时适应两种人群。
可选地，请一并参阅图16和图10，每个铰链转轴41的中心点到对应的骨传导扬声机构20的贴合面21的中心点O之间的距离h 3与眼镜框31的对称中心点到两个铰链转轴41的中心点的连线的垂直距离h 2的比例h 3/h 2为0.1～1.5。
其中，每个铰链转轴41的中心点到对应的骨传导扬声机构20的贴合面21的中心点O之间的距离h 3对应于铰链转轴41的中心点到贴合面21与用户耳廓背面的贴合处的距离；而眼镜框31的对称中心点到两个铰链转轴41的中心点的连线的垂直距离h 2对应于用户头部的前部到耳后的垂直距离。在用户头部的前部到耳后的垂直距离为一定时，若铰链转轴41的中心点到贴合面21与用户耳廓背面的贴合处的距离较大，即上述比例较大时，说明铰链转轴41的中心点到对应的骨传导扬声机构20的贴合面21的中心点O之间的距离较大，则骨传导扬声机构20容易贴合在耳廓背面较为靠下的部位；而在上述比例较小时，说明铰链转轴41的中心点到对应的骨传导扬声机构20的贴合面21的中心点O之间的距离较小，则骨传导扬声机构20容易贴合在耳廓背面较为靠上的部位，从而会影响骨传导扬声机构20对声音/振动的传递效率，进而影响音质。
其中，h 3/h 2还可以为0.125～0.35，具体如0.125、0.15、0.20、0.25、0.30、0.35等，可根据用户的不同需求设计不同的比例，此处不做限定。
进一步地，还可以根据上述各参数的不同设置不同规格的骨传导发声装置，以使得用户可以根据自己的头型进行选择，以满足用户的使用需求。
请进一步一并参阅图17和图18，图17是本申请骨传导发声装置一实施方式的局部截面示意图，图18是图17中A部分的放大结构示意图。本实施方式中，骨传导发声装置进一步包括第一连接线50，眼镜架30进一步包括转轴组件33。
其中，第一连接线50为起机械连接作用或电连接作用的连接线，本实施方式中，两条眼镜腿112内分别设置有功能组件，且需要通过第一连接线50进行电性连接，以实现特定功能。转轴组件33的数量为两个，分别用于连接眼镜框31和两条眼镜腿32，以使得眼镜框31和眼镜腿32能够绕转轴组件33进行相对转动。其中，转轴组件33沿轴向设置有转轴走线通道331，第一连接线50穿设于转轴走线通道331内并分别延伸至眼镜框31及眼镜腿32。
具体地，本实施方式中，第一连接线50通过转轴走线通道331后，一端直接延伸至一条眼镜腿32，另一端进入至眼镜框31，并沿第一安装槽111进一步延伸至另一条眼镜腿32，进而电连接分别位于两条眼镜腿32内的两个功能组件16。
容易理解地，眼镜框31和眼镜腿32之间发生折叠时，转轴组件33附近的结构的相对位置会产生改变，而此时，若位于眼镜框31和眼镜腿32之间的连接处的第一连接线50直接绕转轴组件33的外围设置，那么此处的第一连接线50将会随着眼镜框31或者眼镜腿32的折叠而发生挤压或拉扯，甚至变形、断裂，从而影响第一连接线50的稳定性，缩短第一连接线50的使用寿命。
而本实施方式中，转轴组件33沿轴向设置有转轴走线通道331，位于眼镜框31和眼镜腿32的连接处的第一连接线50贯穿于该转轴走线通道331内部，从而在眼镜框31与眼镜腿32之间发生折叠时，位于转轴走线通道331内的第一连接线50仅会随转轴组件33的转动而产生一定量的旋转，以减少对第一连接线50的折叠挤压或拉扯，从而对第一连接线50起到一定的保护作用，提高第一连接线50的稳定性，延长第一连接线50的使用寿命。
本实施方式中转轴走线通道331的内径大于第一连接线50的外径，例如，转轴走线通道331的内径可以为第一连接线50的外径的两倍，从而能够减小转轴走线通道331的 内侧壁对第一连接线50的束缚作用，以在眼镜框31与眼镜腿32之间发生折叠时减小第一连接线50的转动幅度。
请进一步一并参阅图18和图19，图19是本申请骨传导发声装置一实施方式中转轴组件的与第一连接线结构示意图。本实施方式中，转轴组件33包括第一转轴332，第一转轴332的两端分别连接眼镜框31和眼镜腿32，转轴走线通道331沿第一转轴332的轴向设置，转轴走线通道331通过设置于第一转轴332的至少一端面上的走线口3321与外部连通，第一连接线50经走线口3321延伸至眼镜框31或眼镜腿32。
需要指出的是，本实施方式中第一转轴332可与眼镜框31和眼镜腿32的其中之一转动连接，并与其中另一固定连接，以使得眼镜框31和眼镜腿32绕第一转轴332转动连接。
具体地，本实施方式中，转轴走线通道331设置于第一转轴332内，并进一步通过走线口3321与外部连通。
具体地，转轴走线通道331贯穿第一转轴332的至少一端面而形成转轴走线通道331的走线口3321，从而使第一连接线50能够通过第一转轴332的至少一端面由转轴走线通道331延伸而出，进而延伸至眼镜框31或眼镜腿32。容易理解地，第一转轴332的端面外围具有较大的活动空间，由该第一转轴332的端面延伸而出的第一连接线50能够容置于该活动空间之内，而若该端面处第一转轴332与对应的眼镜框31或眼镜腿32是转动连接，那么当眼镜框31和眼镜腿32之间发生折叠转动时，该端面上的走线口3321附近的第一连接线50随着第一转轴332的转动而发生一定的程度的扭转时能够通过该活动空间进行适当的缓冲，并能够变扭转为移动，从而进一步降低第一连接线50的扭转程度，提高第一连接线50的稳定性。
请参阅图20，图20是本申请骨传导发声装置一实施方式中第一转轴的结构示意图。本实施方式中，走线口3321包括第一走线口33211和第二走线口33212，并分别设置于第一转轴332的两端面，转轴走线通道331分别通过两个走线口3321与外部连通，从而使得第一连接线50贯穿第一转轴332的两端面并经第一走线口33211和第二走线口33212分别延伸至眼镜框31和眼镜腿32。
也就是说，本应用场景中，眼镜框31和眼镜腿32之间的连接处的第一连接线50设置于第一转轴332内的转轴走线通道331中，并分别通过第一转轴332的两端面由转轴走线通道331延伸而出。此时，由于第一转轴332的两端面外围均有较大的活动空间，因此由第一转轴332两端面延伸而出的第一连接线50在眼镜框31与眼镜腿32之间发生相对转动时仅发生移动或小幅度扭转而均不会发生挤压拉扯而变形。
请继续参阅图19，本实施方式中，走线口3321包括第一走线口33213和第二走线口33214。其中，第一走线口33213设置于第一转轴332的端面上，第二走线口33214则设置于第一转轴332的侧壁上，使得转轴走线通道331一端沿轴向通过第一走线口33213贯通第一转轴332的端面，另一端通过第二走线口33214贯通第一转轴332的侧壁，进而与外部连通，第一连接线50经第一走线口33213和第二走线口33214分别延伸至眼镜框31和眼镜腿32。
同样地，设置第一走线口33213的第一转轴332端面附近具有较大的活动空间，在眼镜框31和眼镜腿32之间发生相对运动时，第一走线口33213附近的第一连接线50仅发生相对移动，或者小幅度的扭转。
在一个应用场景中，第一转轴332与眼镜框31和眼镜腿32中靠近第二走线口33214设置的一者固定连接，且与眼镜框31和眼镜腿32中靠近第一走线口33213设置的另一者转动连接。也就是说，第一转轴332在设置于端面的走线口3321处与眼镜框31或眼镜腿32中的一个转动连接，而第一转轴332在设置于侧壁的走线口3321处与眼镜框31或眼镜腿32中的另一个固定连接。
在一个应用场景中，第一转轴332在第一走线口33213处靠近眼镜框31，并与眼镜框31转动连接，第一转轴332在第二走线口33214处靠近眼镜腿32，并与眼镜腿32固定连 接。
需要指出的是，本应用场景中，虽然第一转轴332与眼镜框31转动连接，在眼镜框31与眼镜腿32之间发生相对转动时会带动第一连接线50在第一走线口33213处发生相对运动，但是由于第一走线口33213设置于第一转轴332的端面上，与上述实施方式中类似，第一转轴332的端面处具有较大的活动空间，而当眼镜框31和眼镜腿32之间发生折叠转动时，该端面上的走线口3321附近的第一连接线50随着第一转轴332的转动而发生一定的程度的扭转时能够通过该活动空间进行适当的缓冲，并能够变扭转为移动，或者小幅度的扭转，而不会对连接线产生挤压或拉扯，从而能够提高连接线的稳定性以及延长连接线的使用寿命。
另外，第一转轴332在第二走线口33214处与眼镜腿32固定连接，容易理解地，在眼镜框31与眼镜腿32之间发生相对转动时，眼镜腿11与第一转轴332之间保持同步，因此，转轴走线通道331内的第一连接线50经第二走线口33214延伸入眼镜腿11的第一连接线50不会发生扭转、挤压、拉扯。因此，此时第二走线口33214无论是设置在第一转轴332的端面上还是设置在第一转轴332的侧壁上，眼镜框31和眼镜腿32之间的相对转动均不会对此处的第一连接线50产生上述扭转、挤压、拉扯等。
而在其它实施方式中，若在第二走线口33214处第一转轴332与眼镜腿32转动连接，在二者之间发生相对转动而带动第一连接线50发生移动时，会受到第二走线口33214处第一转轴332的侧壁的约束，从而使得第一连接线50受到第一转轴332的侧壁与眼镜腿32之间的挤压。
若第一转轴332在第一走线口33213处靠近眼镜腿32，并与眼镜腿32转动连接，第一转轴332在第二走线口33214处靠近眼镜框31，并与眼镜框31固定连接，同样的道理，在眼镜框31与眼镜腿32之间发生折叠时，转轴走线通道331内及第一走线口33213和第二走线口33214附近的第一连接线50仍然仅是发生小幅度扭转或者移动。
请继续参阅图19，在一实施方式中，转轴组件33进一步包括与第一转轴332同轴且间隔的第二转轴333。
本实施方式中，第二转轴333设置在第一转轴332靠近第一走线口33213的一侧。当然，在其他实施方式中，第二转轴333也可以设置在第一转轴332靠近第二走线口33214的一侧。
请进一步参阅图21，图21是本申请骨传导发声装置一实施方式的局部结构爆炸图。本实施方式中，眼镜框31包括第一凸耳311，具体地，第一凸耳311的数量为两个，分别设置在眼镜框31连接两条眼镜腿32的两端，并分别凸出朝向对应的眼镜腿32。
眼镜腿32包括间隔设置的第二凸耳3201和第三凸耳3202。其中，第二凸耳3201和第三凸耳3202均朝向所在的眼镜腿32所连接的眼镜框31的端部。且在用户佩戴该眼镜时，第二凸耳3201和第三凸耳3202于远离用户头部的一侧连接在一起，从而使得眼镜在外观上更加整体更加美观。在一个应用场景中，间隔设置的第二凸耳3201和第三凸耳3202通过在眼镜腿32朝向眼镜框31的一端的中部设置凹槽而形成。
进一步地，第一转轴332和第二转轴333互相靠近的端部均与第一凸耳311连接，第一转轴332和第二转轴333互相远离的端部分别与第二凸耳3201和第三凸耳3202连接，以将第一凸耳311保持在第二凸耳3201与第三凸耳3202之间。
其中，请继续参阅图19，在一实施方式中，第一走线口33213设置于第一转轴332靠近第二转轴333的端面，第二走线口33214设置于第一转轴332靠近第二凸耳3201的侧壁上，第一转轴332与第一凸耳311转动连接，并与第二凸耳3201固定连接。
具体地，本实施方式中，转轴走线通道331内的第一连接线50的一端由第一走线口33213并经过第一转轴332与第二转轴333之间的间隔延伸而出。进一步地，在一应用场景中，第一凸耳311设置有与第一走线口33213连通的走线通道，从而使得第一连接线50进一步由第一凸耳311进入眼镜框31。
另外，转轴走线通道331内的第一连接线50的另一端由第二走线口33214延伸而出。进一步地，在一应用场景中，第三凸耳3202设置有与第二走线口33214连通的走线通道，从而使得第一连接线50能够进一步经由第三凸耳3202的走线通道进入眼镜腿32。
其中，第二走线口33214可以为设置在第一转轴332的侧壁上而不与第一转轴332的端部贯通的一与转轴走线通道331连通的通孔。本实施方式中，第二走线口33214进一步沿第一转轴332的侧壁贯通至第一转轴332远离第一走线口33213的端部。容易理解地，本实施方式中的第二走线口33214处具有更大的空间，从而在此处的第一连接线50因一些原因而产生移动时，能够进一步减小对第一连接线50的限制，进一步减少因第一转轴332的侧壁的阻挡而受到的损伤。
请进一步一并参阅图21、图22和图23，图22为本申请骨传导发声装置一实施方式中眼镜框与眼镜片的结构示意图，图23为本申请骨传导发声装置一实施方式中眼镜腿的局部结构示意图。本实施方式中，第一凸耳311和第二凸耳3201分别同轴设置有第一容置孔3111和第二容置孔32011，其中第一容置孔3111和第二容置孔32011的尺寸设置成允许第一转轴332从眼镜腿32的外部经第二容置孔32011插入到第一容置孔3111内，并且使得第一转轴332与第二容置孔32011过盈配合且与第一容置孔3111间隙配合。
具体地，第二容置孔32011为贯通第二凸耳3201的通孔，第一容置孔3111则对应于第二容置孔32011贯穿至少部分第一凸耳311。其中，第一容置孔3111的内径大于第二容置孔32011，第一转轴的外径尺寸介于第一容置孔3111与第二容置孔32011之间，从而使得第一转轴332与眼镜腿32固定连接，而与眼镜框31转动连接，从而使得眼镜框31与眼镜腿32之间能够绕第一转轴332转动而折叠或打开。
进一步地，在一实施方式中，第一凸耳311和第三凸耳3202分别同轴设置有第三容置孔3112和第四容置孔32021，其中第三容置孔3112和第四容置孔32021的尺寸设置成允许第二转轴333从眼镜腿32的外部经第四容置孔32021插入到第三容置孔3112内，并且使得第二转轴333与第三容置孔3112过盈配合且与第四容置孔32021间隙配合，或使得第二转轴333与第三容置孔3112间隙配合且与第四容置孔32021过盈配合。
本实施方式中，第三容置孔3112和第四容置孔32021均与第一容置孔3111和第二容置孔32011同轴设置。其中，第三容置孔3112贯穿至少部分第一凸耳311，在一个应用场景中，第一容置孔3111与第三容置孔3112同轴且贯通设置。具体地，如上述实施方式中所述，眼镜框31的第一凸耳311设置有与第一走线口33213连通的走线通道，第一容置孔3111与第三容置孔3112分别设置于该位于第一凸耳311内的走线通道的两侧，并均贯通该走线通道。第四容置孔32021贯通第三凸耳3202设置。其中，第二转轴333的外径尺寸介于第三容置孔3112与第四容置孔32021的内径之间，且第三容置孔3112的内径大于第四容置孔32021，或者，第四容置孔32021的内径大于第三容置孔3112，从而使得第二转轴333与眼镜腿32固定连接，而与眼镜框31转动连接，或者第二转轴333与眼镜框31固定连接，而与眼镜腿32转动连接，进而使得眼镜框31与眼镜腿32之间能够绕第一转轴332转动而折叠或打开。
其中，在一实施方式中，第二转轴333可以为实心轴，其直径小于第一转轴332的直径。在佩戴状态下，第二转轴333位于眼镜腿32的上侧，第一转轴332位于眼镜腿32的下侧。
需要指出的是，由于转轴走线通道331设置在第一转轴332的内部，从而使得第一转轴332的外径较大，而不利于满足用户在美观上的需求。因此，本实施方式中进一步设置具有较小外径的第二转轴333，并使得在用户佩戴眼镜时，第二转轴333设置在容易被发现的上部，而第一转轴332则设置在不容易被观察到的下部，由于第二转轴333的外径较小，从而能够在一定程度上改善眼镜的整体美观效果。
当然，在其它实施方式中，第一转轴332和第二转轴333也可以为其它情况，例如，第二转轴333还可以为空心轴，且第二转轴333的直径也可以大于第一转轴332的直径， 或者，在佩戴状态下，第二转轴333位于眼镜腿32的下侧，第一转轴332位于眼镜腿32的上侧等，此处不做限定。
另外，请继续参阅图19，第一转轴332的用于设置第一走线口33213的端面3322与第一转轴332的用于定义转轴走线通道331的内壁面3323的连接处呈弧形设计。容易理解地，在眼镜框31与眼镜腿32之间通过转轴组件33进行转动时，由于第一转轴332与眼镜框31之间为转动连接，从而会带动第一走线口33213处的第一连接线50移动，本实施方式中，将第一转轴332的上述端面3322与内壁面3323的连接处进行弧形设计，能够避免在第一走线口33213处的第一连接线50移动并与第一转轴332接触时因上述连接处过于尖锐而割伤第一连接线50，从而进一步对第一连接线50起到保护作用。
在一个应用场景中，第一转轴332的用于设置第二走线口33214的端面与第一转轴332的用于定义转轴走线通道331的内壁面3323的连接处也呈弧形设计，同样地，通过这种方式也能够进一步对第一连接线50起到保护作用。
请进一步参阅图24和图25，铰链40还包括铰链座42以及铰链臂43，其中，铰链臂43通过铰链转轴41与铰链座42转动连接。
其中，铰链40的铰链座42连接设置在镜腿主体321上，进而将铰链40设置于镜腿主体321远离眼镜框31的端部。
具体地，镜腿主体321沿长度方向设置有与镜腿主体321远离眼镜框31的端部的的端面连通的铰链腔3211，镜腿主体321的侧壁上设置有与铰链腔3211连通的第一插置孔3212，铰链座42的远离铰链臂43的一端从镜腿主体321的端面插入至铰链腔3211，并由插置在第一插置孔3212内的固定件323固定在铰链腔3211内而将铰链40与镜腿主体321连接。
其中，镜腿主体321在成型过程中形成铰链腔3211，例如，镜腿主体321的材质可以为橡胶或者塑料等，此时可在镜腿主体321注塑成型过程中形成铰链腔3211。铰链腔3211的形状与铰链座42匹配，以使得铰链座42能够容置于铰链腔3211内。在本实施方式中，镜腿主体321沿长度方向可以为长直杆状，对应地，镜腿主体321则可以为沿长度方向的直杆，铰链腔3211设置于直杆中，进一步地，铰链座42与铰链腔3211匹配以容置于铰链腔3211内进而实现铰链40的安装。当然，在其它实施方式中，镜腿主体321也可以为弧形杆等其它形状。
另外，第一插置孔3212也可在镜腿主体321成型过程中形成，或者在成型后进一步通过钻孔等方法在镜腿主体321的侧壁上形成。具体地，本实施方式中，第一插置孔3212的形状可以为圆形，在其它实施方式中还可以为方形、三角形等其它形状。固定件323的形状与第一插置孔3212匹配，以使得固定件323能够从镜腿主体321的外部插入第一插置孔3212，并进而通过抵紧铰链座42的侧壁的方式，或者进一步穿透铰链座42的外壁以插接的方式等将铰链座42固定在铰链腔3211内。具体地，可以在第一插置孔3212的内壁与固定件323的外壁上设置匹配的螺纹，以使得固定件323能够通过螺接的方式与第一插置孔3212连接以进一步将铰链座42固定在铰链腔3211内。当然，也可以通过其它方式，例如通过第一插置孔3212与固定件323的过盈配合等方式进行连接。
进一步地，铰链臂43可与连接件322连接，从而使得连接件322在与铰链臂43连接后，进一步通过将铰链座42装设在镜腿主体321的铰链腔3211内从而与镜腿主体321之间能够绕铰链转轴41进行转动，且将骨传导扬声机构20连接设置在铰链臂43远离铰链座42一端，从而通过铰链40连接在镜腿主体321远离眼镜框31的端部。
上述方式中，镜腿主体321上设置有与镜腿主体321的端面连通的铰链腔3211，铰链40通过将铰链座42容置于该铰链腔3211内，并进一步将固定件323通过第一插置孔3212穿透镜腿主体321的侧壁从而将容置于铰链腔3211内的铰链座42固定在铰链腔3211内，从而能够实现铰链40相对于镜腿主体321可拆装，从而在骨传导扬声机构20或眼镜框31、镜腿主体321等损坏时，便于进行更换。
进一步地，请继续参阅图25，在一实施方式中，铰链座42上设置有与第一插置孔3212对应的第二插置孔421，固定件323进一步插置于第二插置孔421内。
具体地，第二插置孔421的形状与固定件323匹配，以使得固定件323在穿过第一插置孔3212后，进一步插入第二插置孔421中以将铰链座42固定，从而减少铰链座42在铰链腔3211内的晃动，使得铰链40固定得更加牢固。具体地，与第一插置孔3212和固定件323的连接方式相似，第二插置孔421的内侧壁上可设置有与固定件323对应的外壁上互相匹配的螺纹，以使得固定件323与铰链座42螺接在一起；或者，第二插置孔421的内壁与固定件323的对应接触的位置处的外侧壁均为平滑的面，固定件323与第二插置孔421过盈配合，此处不做具体限定。
进一步地，第二插置孔421还可贯穿铰链座42的两侧边设置，从而使得固定件323能够进一步穿透整个铰链座42，以将铰链座42更加牢固得固定在铰链腔3211内。
请进一步参阅图26，本实施方式中，在垂直于镜腿主体321的长度方向的截面上，铰链座42的截面形状与铰链腔3211的截面形状相匹配，以使得在插入后铰链座42与镜腿主体321之间形成密封配合。
其中，在图26中所示的截面上，铰链座42的截面形状和铰链腔3211的截面形状可以为任意形状，只要能够使得铰链座42从镜腿主体321的远离铰链臂43的端面插入至该铰链腔3211中即可。进一步地，第一插置孔3212设置在铰链腔3211的侧壁上，并贯通铰链腔3211的侧壁与铰链腔3211连通。
在一个应用场景中，铰链座42的截面形状和铰链腔3211的截面形状均呈矩形设置，第一插置孔3212垂直于矩形的一侧边设置。
具体地，本应用场景中，可以进一步对铰链座42外侧壁的棱角或铰链腔3211的内侧壁的角倒圆角设置，使得铰链座42与铰链腔3211的接触更加平滑，从而使得铰链座42能够顺利得插入至铰链腔3211内。
需要进一步指出的是，在铰链40装配前，铰链腔3211内存储有一定量的气体，因此若铰链腔3211仅为一端开口的腔体，那么在装配过程当中将会由于铰链腔3211内的气体难以排出而不利于铰链座42插入，从而影响装配。本实施方式中的第一插置孔3212贯通铰链腔3211的侧壁而与铰链腔3211连通，能够在装配过程中辅助将内部的气体通过铰链腔3211由第一插置孔3212排出，从而有助于铰链40的正常装配。
请进一步参阅图27，在一实施方式中，骨传导发声装置进一步包括设置于铰链40外侧的第二连接线60。
其中，第二连接线60与第一连接线50类似，可以为具有电性连接作用和/或机械连接作用的连接线。本实施方式中，铰链40等用于将骨传导扬声机构20连接于镜腿主体321远离眼镜框31的端部，而与骨传导扬声机构20相关的控制电路等可设置于镜腿主体321当中，此时，需要第二连接线60将骨传导扬声机构20与镜腿主体321中的控制电路等电连接在一起。具体地，第二连接线60可位于铰链座42和铰链臂43的一侧，与铰链40设置于同一容置空间当中，其中，第二连接线60与第一连接线50可互相连接，或者也可互相独立。
进一步地，铰链座42包括第一端面422，铰链臂43具有与第一端面422相对设置的第二端面431，容易理解地，第一端面422和第二端面431之间存在一定的间隙，以使得铰链座42和铰链臂43能够绕铰链转轴41进行相对转动。本实施方式中，在铰链臂43与铰链座42进行相对转动过程中，第一端面422与第二端面431之间也随之发生相对位置的变化，从而使得二者之间的间隙变大或者变小。
而本实施方式中，第一端面422与第二端面431之间的间隙始终保持为大于或小于第二连接线60的直径，从而使得位于铰链40外侧的第二连接线60不至于在铰链座42与铰链臂43的相对转动过程中夹入第一端面422与第二端面431之间的间隙中，进而减少铰链对第二连接线60的损伤。具体地，第一端面422与第二端面431之间的间隙在铰链臂 43与铰链座42进行相对转动过程中与第二连接线60的直径的比例可始终保持为大于1.5或小于0.8，例如大于1.5、1.7、1.9、2.0等，或小于0.8、0.6、0.4、0.2等，此处不做具体限定。
其中，在一实施方式中，骨传导发声装置还可进一步包括保护套管70。请一并参阅图4、图28至图31，该保护套管70套设在铰链40的外围，并随铰链40发生弯折，其中保护套管70包括沿保护套管70的长度方向间隔设置的多个环状凸脊部71以及设置于环状凸脊部71之间并用于连接相邻设置的两个环状凸脊部的环状连接部72，其中环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度。
其中，保护套管70的长度方向与铰链40的长度方向一致，保护套管70具体可沿铰链座42和铰链臂43的长度方向设置。该保护套管70可以由软质材料做成，例如软质的硅胶、橡胶等。
环状凸脊部71可由保护套管70的外侧壁进一步向外凸出形成，而环状凸脊部71对应的保护套管70的内侧壁的形状此处不做具体限定。例如，内侧壁可以为平滑的，或者内侧壁上对应环状凸脊部71的位置还可设置凹陷等。
环状连接部72用于连接相邻的环状凸脊部71，具体连接于环状凸脊部71的靠近保护套管70内部的边缘区域，从而在保护套管70的外侧壁一侧可相对于环状凸脊部71呈凹陷设置。
具体地，环状凸脊部71和环状连接部72的数量可以根据实际使用情况而定，例如，可以根据保护套管70的长度、环状凸脊部71和环状连接部72本身在保护套管70长度方向上的宽度等情况设定。
进一步地，环状凸脊部71和环状连接部72的管壁厚度分别是指环状凸脊部71和环状连接部72所对应的保护套管70的内侧壁与外侧壁之间的厚度。本实施方式中，环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度。
容易理解地，在铰链40的铰链座42和铰链臂43之间绕铰链转轴41相对转动时，铰链座42和铰链臂43之间的角度发生变化，从而使得保护套管70发生弯折，如图30和图31中所示。具体地，在保护套管70随铰链40发生弯折时，位于保护套管70所形成的弯折形状的外侧区域的环状凸脊部71和环状连接部72处于拉伸状态，而位于弯折形状的内侧区域的环状凸脊部71和环状连接部72处于挤压状态。
本实施方式中，环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度，从而使得环状凸脊部71相对于环状连接部72更硬，从而在保护套管70处于弯折状态时，处于弯折形状的外部一侧的保护套管70处于拉伸状态，环状凸脊部71能够为保护套管70提供一定的强度支撑；同时，处于弯折状态的内部一侧的保护套管70区域受到挤压，环状凸脊部71还能够承受一定的挤压力，从而对保护套管70起到保护作用，提高保护套管70的稳定性，延长保护套管70的寿命。
进一步地，需要指出的是，保护套管70的形状与铰链40所处的状态一致。在一个应用场景中，保护套管70的沿长度方向上且绕转轴转动的两侧都可能受到拉伸或者挤压。在另一个应用场景中，铰链40的铰链座42和铰链臂43仅能够绕铰链转轴41在小于或等于180°的范围内进行转动，也就是说，保护套管70仅能够朝向一侧进行弯折，那么保护套管70的沿长度方向上的两侧中有一侧可受到挤压，另一侧可受到拉伸，此时，可以根据保护套管70两侧受力的不同，而将保护套管70受力不同的两侧设置为不同的结构。
在一实施方式中，环状凸脊部71在保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状外部一侧的沿保护套管70长度方向的宽度大于朝向弯折形状内部一侧的沿保护套管70长度方向的宽度。
其中，沿保护套管70长度方向上，增大环状凸脊部71的宽度能够进一步提高保护套管的强度。同时，本实施方式中，铰链座42和铰链臂43之间的初始夹角的角度小于180°，此时，若保护套管70的环状凸脊部71均匀设置，则会使得保护套管70在原始状态下便 受到挤压。本实施方式中，对应于弯折状态时朝向弯折形状的外侧区域一侧的环状凸脊部71的宽度较大，从而能够扩大该侧保护套管70的长度，从而在提高保护套管70的强度的同时，还使得在保护套管70弯折时，在一定程度上减少拉伸侧的拉伸程度；同时，环状凸脊部71在保护套管70处于弯折状态时朝向弯折形状的内侧区域一侧的沿保护套管70长度方向的宽度较小，能够增大挤压的环状连接部72在保护套管70长度方向上的空间，从而能够在一定程度上缓解挤压侧的挤压。
进一步地，在一个应用场景中，环状凸脊部71的宽度在从朝向弯折形状的外侧区域一侧向朝向弯折形状的内部区域一侧逐渐变小，从而使得保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状的外侧区域一侧的宽度大于朝向弯折形状的内侧区域一侧的宽度。
容易理解地，环状凸脊部71围绕设置在保护套管70的外围，在保护套管70的长度方向上，一侧对应拉伸侧，另一侧对应挤压侧。本实施方式中，环状凸脊部71的宽度从朝向弯折形状的外侧区域一侧向朝向弯折形状的内侧区域一侧逐渐变小，从而使得宽度的较为均匀，能够在一定程度上提高保护套管70的稳定性。
其中，在一实施方式中，环状凸脊部71在保护套管70处于弯折状态时朝向保护套管70所形成的弯折形状的外侧区域一侧的保护套管70内部的内环面设置有凹槽711。
具体地，本实施方式中的凹槽711沿垂直于保护套管70的长度方向设置，进而使得对应的环状凸脊部71在保护套管70在长度方向上受到拉伸时能够进行适当的伸展。
如上所述，在保护套管70处于弯折状态时，朝向保护套管70所形成的弯折形状外部一侧的保护套管70处于拉伸状态，本实施方式中，进一步在对应的环状凸脊部71对应的保护套管70内部的内环面上设置凹槽711，从而能够在该侧保护套管拉伸时，凹槽711对应的环状凸脊部71能够适当伸展以承担部分拉伸，从而减少该侧保护套管所受到的拉力，进而对保护套管70起到保护作用。
需要指出的是，在保护套管70处于弯折状态时，朝向弯折形状的内侧区域的一侧的环状凸脊部71可在对应的保护套管70的内侧壁上不设置凹槽71。在一实施方式中，凹槽71沿保护套管70长度方向的宽度在从朝向弯折形状的外侧区域一侧向朝向弯折形状的内侧区域一侧逐渐变小，从而使得在朝向弯折形状的内侧区域一侧的环状凸脊部71所对应的保护套管70的内侧壁上没有凹槽711设置。
具体地，保护套管70可以与分别设置在保护套管70的长度方向上的两侧的镜腿主体321以及骨传导扬声机构20连接在一起。在一个应用场景中，保护套管70还可以与骨传导发声装置中的其它结构如一些部件的保护盖层等一体成型，从而使得骨传导发声装置更加封闭、一体。
具体地，请进一步一并参阅图32至图36，在一实施方式中，铰链40的铰链臂43具有彼此连接的第一支撑面432和第二支撑面433。铰链40还包括支撑件44和弹性件45。支撑件44活动设置于铰链座42上，且具有第三支撑面441，弹性件45用于将支撑件44朝向铰链臂43进行弹性偏置，以使得第三支撑面441能够分别弹性抵接于第一支撑面432和第二支撑面433上。
其中，在骨传导扬声机构20或连接件322受到外力作用而带动铰链臂43相对铰链座42进行转动时，由第一支撑面432和第二支撑面433的连接处434推动支撑件44克服弹性件45的弹性偏置而反向移动，进而使得第三支撑面441从与第一支撑面432和第二支撑面433中的一者弹性抵接切换到与第一支撑面432和第二支撑面433中的另一者弹性抵接。
在一个应用场景中，支撑件44连接设置在弹性件45朝向铰链臂43的一端，且使得第三支撑面441朝向铰链臂43一侧，在铰链臂43受到外力作用而绕铰链转轴41相对铰链座42转动的过程中，能够推动第三支撑面441而使得支撑件44压迫弹性件45，并进一步在弹性件45的作用下发生弹性偏置。当然，支撑件44也可以与弹性件45不连接，而 仅仅是抵接在支撑件44的一侧，只要能够使得支撑件44实现上述弹性偏置即可。
其中，第一支撑面432和第二支撑面433分别为铰链臂43的相邻的且至少部分与铰链转轴41的中轴线平行的两个侧面，或者是两个侧面的一部分，在铰链臂43相对铰链座42转动时，第一支撑面432和第二支撑面433随铰链臂43围绕铰链转轴41发生转动，从而使得铰链臂43的不同侧面朝向铰链座42，进而使得铰链臂43相对于铰链座42能够具有不同的相对位置关系。
另外，弹性件45为能够提供弹力且能够在弹力方向上压缩以提供一定的压缩空间的构件。例如，弹性件45可以为弹簧，弹簧的一端抵接支撑件44，在支撑件44的第三支撑面441受到朝向弹性件45的推动作用时，弹性件45反抗支撑件44并发生压缩从而为支撑件44的第三支撑面441所朝向的方向上提供空间，以使得在铰链转轴41的相对位置不变时，仍有足够的空间使得铰链臂43不同的侧面转动至铰链转轴41与第三支撑面441之间。
具体地，在铰链臂43相对于铰链座42转动时，铰链转轴41的相对位置不发生改变，铰链臂43与铰链座42的第三支撑面441的接触位置发生变化，而由于铰链臂43的不同的位置到铰链转轴41的距离不同，因此，在铰链臂43的不同的位置如第一支撑面432和第二支撑面433的不同位置与第三支撑面441接触时，所述需要的铰链转轴41到铰链臂43与第三支撑面441的接触点之间的空间不同。而受弹力作用以及空间等的限制，弹性件45压缩而提供的空间可能是有限的。因此，在铰链臂43相对于铰链座42转动的过程中，在垂直于铰链转轴41的中轴线的截面上若铰链臂43上某一位置与铰链转轴41的距离过大，该位置在转动过程中将会卡持于第三支撑面上的另一位置而无法使得铰链臂43继续转动，从而使得铰链臂43和铰链座42仅能够在一定的范围内相对转动。在一个应用场景中，在铰链臂43与铰链座42之间绕铰链转轴41相对转动的过程中，仅有第一支撑面432与第二支撑面433以及第一支撑面432与第二支撑面433的连接处434所对应的区域能够与第三支撑面441抵接。
进一步地，本实施方式中，第一支撑面432和第二支撑面433可以均为平面，铰链40可具有第三支撑面441抵接于第一支撑面432，以及第三支撑面441抵接于第二支撑面433两种相对稳定的状态。
当然，在本实施方式中，第一支撑面432和第二支撑面433也可能是具有一定弧度的曲面，甚或还可包括不同的子支撑面，只要能够使得铰链臂43和铰链座42之间的位置关系具有对应的至少两种相对稳定的状态即可，此处不做具体限定。另外，铰链臂43上还可以设置其它更多的支撑面，以在铰链臂43受到外力而绕铰链转轴41与铰链座42之间发生相对转动时，通过铰链臂43上不同的支撑面与第三支撑面441发生弹性抵接而使得铰链臂43与铰链座42之间具有多种不同的相对位置关系，此处不做具体限定。
具体地，以初始状态为第一支撑面432与支撑件44的第三支撑面441抵接为例，具体如图32和图33中所示。此时弹性件45可以具有弹性压缩形变，也可以处于原始的自然状态，此处不做限定。在铰链40受到外力作用而使得铰链臂43绕铰链转轴41与铰链座42发生相对转动以使得第二支撑面433逐渐靠近第三支撑面441时，第一支撑面432和第二支撑面433的连接处434与第三支撑面441接触，由于连接处434到铰链转轴41的距离大于第一支撑面432到铰链转轴41的距离，从而使得连接处434抵接支撑件44并推动支撑件44移动朝弹性件45的方向移动，进而使得弹性件45克服推力而产生压缩。且在铰链臂43进一步受力时，连接处434逐渐靠近铰链转轴41的与第三支撑面441之间的区域，在此过程中，铰链转轴41到第三支撑面441之间的距离逐渐增大；容易理解地，在连接处434与铰链转轴41的连线垂直于第三支撑面441时，在垂直于铰链转轴41的中轴线的截面上，铰链转轴41到第三支撑面441的距离等于铰链转轴41到连接处434的距离，此时铰链转轴41距离第三支撑面441最远；而在此时，若继续对铰链40施力，则铰链转轴41到第三支撑面441的距离将会逐渐变小，从而所需要的弹性件45压缩的空间减 小，并进而使得弹性件45逐渐释放弹力而回复，直到连接处434离开第三支撑面441而使得第二支撑面433与第三支撑面441抵接，从而实现从第一支撑面432与第三支撑面441抵接到第二支撑面433与第三支撑面441抵接之间的切换。
同样地，在初始状态为第二支撑面433与支撑件44的第三支撑面441抵接而向第一支撑面432与支撑件44的第三支撑面441抵接转换的过程(具体如图35和图36中所示)与上述过程类似。
需要指出的是，在第三支撑面441从与第一支撑面432和第二支撑面433中的一者弹性抵接切换到与第一支撑面432和第二支撑面433中的另一者弹性抵接时，铰链40带动骨传导扬声机构20相对于镜腿主体321能够在第一相对固定位置和第二相对固定位置之间进行切换，并在骨传导扬声机构20处于第一相对固定位置时能够贴合于用户的耳廓背面。
本实施方式中，铰链转轴41到连接处434的距离均大于到第一支撑面432和第二支撑面433的垂直距离，从而使得在第三支撑面441从与第一支撑面432和第二支撑面433中的一者弹性抵接切换到与第一支撑面432和第二支撑面433中的另一者弹性抵接的过程中铰链40的状态发生一定程度的跳变。
以第一支撑面432与第三支撑面441弹性抵接切换到第二支撑面433与第三支撑面441弹性抵接为例，铰链转轴41到连接处434的最大距离h 1与铰链转轴41到第一支撑面432的最短距离h 2之间的比例不同时，切换过程中产生的跳变的程度不同。
在一实施方式中，在垂直于铰链转轴41的中轴线的截面上，铰链转轴41到连接处434的最大距离h 1与铰链转轴41到第一支撑面432的最短距离h 2之间的比例介于1.1和1.5之间。
具体地，可通过将铰链转轴41远离第二支撑面433而靠近与第二支撑面433相对的铰链臂43的一侧面设置，来实现铰链转轴41到连接处434的最大距离h 1大于铰链转轴41到第一支撑面432的最短距离h 2，进而满足上述比例。
需要指出的是，h 1与h 2之间的比例过大时，跳变明显，但是可能需要施加较大的力度才能够将第一支撑面432与第三支撑面441弹性抵接切换到第二支撑面433与第三支撑面441弹性抵接，从而在一定程度上为使用带来不便；而h 1与h 2之间的比例过小时，虽然状态的切换较为容易，但是可能跳变程度较小，例如在用户扳动铰链40时没有明显的触感，从而也会带来不便。本实施方式中的将h 1与h 2的比例设置为介于1.1和1.5之间，能够使得第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接时，铰链40的具有较为明显的跳变，从而使得在使用过程中，用户扳动铰链40时具有较为明显的手感，同时也不至于跳变状态太突兀而使得用户难以切换铰链40的状态。
在一个应用场景中，h 1与h 2的比例还可以介于1.2和1.4之间，具体地，h 1与h 2的比例还可以为1.1、1.2、1.3、1.4、1.5等，此处不做具体限定。
另外，第一支撑面432与第二支撑面433在铰链臂43上的位置的设置会影响第三支撑面441与第一支撑面432或第二支撑面433中的一者抵接时铰链臂43与铰链座42之间的夹角的角度，因此，可根据具体的使用需求，而对第一支撑面432与第二支撑面433在铰链臂43上的位置进行不同的设置。其中，铰链臂43与铰链座42之间的夹角具体如图32和图35所示，ω 1为第三支撑面441与第一支撑面432抵接时铰链臂43与铰链座42之间的夹角，ω 2为第三支撑面441与第二支撑面433抵接时铰链臂43与铰链座42之间的夹角。在一实施方式中，铰链臂43与铰链座42均具有一定的长度，铰链臂43设置在铰链座42的长度方向上的端部一侧，第一支撑面432设置在铰链臂43长度方向上靠近铰链座42的端部，而第二支撑面433设置在铰链臂43宽度方向上的一端，且均平行于铰链转轴41的中轴线设置。此时，当第三支撑面441与第一支撑面432弹性抵接时，铰链臂43与铰链座42之间的夹角最大，而在第三支撑面441与第二支撑面433弹性抵接时，铰链臂43与铰链座42之间的夹角最小，从而在第三支撑面441从与第一支撑面432弹性抵接 切换到与第二支撑面433弹性抵接时，铰链座42与铰链臂12之间的夹角由ω 1变为ω 2而变小。
需要进一步指出的是，若将第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接时对铰链臂43所施加的力的方向与铰链臂43自身重力的方向一致，那么在该状态的切换会使得铰链座42与铰链臂12之间的夹角变小时，本实施方式中上述h 1与h 2之间的比例的设置还可以使得在第三支撑面441与第一支撑面432弹性抵接时，骨传导扬声机构20不会随铰链臂43因自身重力而自发得减小其与铰链座42之间的角度。
其中，在本申请骨传导发声装置一实施方式中，请参阅图34，在垂直于铰链转轴41的中轴线的截面上，第一支撑面432和第二支撑面433之间的夹角ω 3为钝角。
其中，铰链40在由第一支撑面432与第三支撑面441弹性抵接的状态向第二支撑面433与第三支撑面441弹性抵接的状态切换时，第一支撑面432和第二支撑面433之间的夹角ω 3越小，则状态切换时铰链座42和铰链臂43之间相对需要转动的角度越大，也就是说，在铰链座42固定不动时，用户需要将铰链臂43扳动较大的角度才能够对铰链40进行状态切换，从而用户使用费力，给用户使用带来不便。
而由于铰链臂43具有一定的长度，且第一支撑面432设置于铰链臂43的长度方向上的一端，而第二支撑面433与第一支撑面432相邻设置于铰链臂43的宽度方向上。通常情况下，第一支撑面432与第二支撑面433垂直设置，此时，在铰链40在上述两种状态之间进行切换时，需要将铰链臂43与铰链座42相对扳动90°。
而本实施方式中，在垂直于铰链转轴41的中轴线的截面上，第一支撑面432和第二支撑面433之间的夹角ω 3为钝角，从而在铰链40于两种状态之间切换时，所铰链臂43与铰链座42所需要相对扳动的角度小于90°。具体地，铰链40用于将镜腿主体321和骨传导扬声机构20连接在一起，在铰链40处于第二支撑面433与第三支撑面441弹性抵接的第二状态时，骨传导扬声机构20处于第一相对固定位置以贴合于用户的耳廓背面，因此在用户需要使用眼镜的骨传导扬声机构20的功能时，仅需要将骨传导扬声机构20转动小于90°的角度即可将其贴合于用户的耳廓背面；另外，在铰链40处于第一支撑面432与第三支撑面441弹性抵接的第一状态时，铰链臂43和连接的骨传导扬声机构20形成一定的角度，从而在用户佩戴眼镜时，铰链臂43和连接的骨传导扬声机构20能够位于用户耳后且朝向用户耳朵的方向设置，从而能够对眼镜起到一定的阻拦、固定作用，不易从用户头部掉落。
需要指出的是，第一支撑面432和第二支撑面433之间的夹角ω 3的具体角度可以根据实际需要进行设定。在该夹角的角度过大时，铰链臂43和连接于铰链臂43远离铰链座42的端部的功能件20与铰链座42之间的夹角将较小，从而在用户佩戴时，铰链臂43与骨传导扬声机构20会因过于靠近用户耳朵而对用户耳朵造成压迫，降低用户的舒适度；而若夹角的角度过小，一方面用户在扳动骨传导扬声机构20而使其在第一相对位置与第二相对位置之间进行切换时，所需要扳动的角度过大，用户使用不方便，另一方面，镜腿主体321与铰链40和骨传导扬声机构20之间所形成的夹角较小而难以起到对眼镜的阻拦、固定的作用，从而使得用户佩戴眼镜时，眼镜容易从用户头部前侧掉落。具体地，可以根据用户的头型设置第一支撑面432和第二支撑面433之间的夹角的具体角度。
具体地，在一个应用场景中，在垂直于铰链转轴41的中轴线的截面上，第一支撑面432和第二支撑面433之间的夹角ω 3的角度介于100°和120°之间，具体可以为100°、110°、120°等。该角度的设置，能够使得用户在佩戴且骨传导扬声机构20处于第一相对固定位置时，骨传导扬声机构20不会过于靠近用户耳朵而对用户耳朵造成不适，且在对骨传导扬声机构20的两种相对位置进行切换时也无需将铰链转动过大的角度，从而方便用户使用。
其中，在第三支撑面441从与第一支撑面432和第二支撑面433中的一者弹性抵接切换到与第一支撑面432和第二支撑面433中的另一者弹性抵接的过程当中，第一支撑面432 和第二支撑面433之间的连接处434抵接第三支撑面441，并推动支撑件44克服弹性件45的弹性偏置而反向移动。以切换前第三支撑面441与第一支撑面432弹性抵接为例，在初始切换时，第一支撑面432逐渐远离第三支撑面441的同时，连接处434逐渐抵接第三支撑面441，并在切换过程中，由第三支撑面441的一侧滑动至第三支撑面441的另一侧，最后进一步过渡至由第二支撑面433与第三支撑面441弹性抵接。在状态切换过程中，连接处434始终与第三支撑面441抵接而相互作用，而连接处434的形状会对状态切换过程产生一定的影响。例如，若第一支撑面432与第二支撑面433之间线连接，那么，连接处434具有较为尖锐的角度，从而在用户扳动铰链座42和/或铰链臂43以进行铰链40的状态切换过程中，一方面，在连接处434与第三支撑面441抵接与连接处434与第一支撑面432和第二支撑面433抵接进行切换时，缓冲较小，切换突兀，从而扳动铰链40的手感差；另一方面，连接处434较为尖锐，会在反复的切换过程中对第三支撑面441造成一定的磨损。
而本申请一实施方式中，在垂直于铰链转轴41的中轴线的截面上，连接处434呈弧形设置。从而使得第一支撑面432与第二支撑面433的连接为弧面连接，进而在铰链40的状态切换的过程当中，与第三支撑面441抵接的连接处434较为平滑，从而用户扳动铰链40时具有较好的手感，而且能够减少在反复的切换过程中对第三支撑面441的损伤。
具体地，在一实施方式中，连接处434呈圆弧设置，而圆弧的曲率不同，其所带来的效果也不同，具体的曲率值需要结合实际使用情况进行设置。本实施方式中圆弧的曲率介于5与30之间，具体还可以为5、10、15、20、25、30等，此处不做限定。
需要指出的是，本实施方式中，圆弧设置的连接处434的曲率能够使得用户在扳动铰链40以使得骨传导扬声机构20在第一相对固定位置与第二相对固定位置之间切换时，具有较好的手感。
在一实施方式中，第三支撑面441设置成使得在第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接时所需的外力不同于在第三支撑面441从与第二支撑面433弹性抵接切换到与第一支撑面432弹性抵接时所需的外力。
需要指出的是，铰链40状态的切换会带动骨传导扬声机构20相对于镜腿主体321在第一相对固定位置和第二相对固定位置之间进行切换。对应地，两种相对固定位置分别对应用户使用骨传导扬声机构20和用户不使用骨传导扬声机构20两种情况，而用户在佩戴眼镜时，手在头部后侧施力以切换两种状态时施力的难易程度并不相同，因此，对应地将不同状态的切换设计为需要施加不同的外力，能够方面用户使用。
具体地，在一实施方式中，当第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接时，对应于将骨传导扬声机构20由第二相对固定位置扳动至第一相对固定位置从而贴合于用户的耳廓背面。
进一步地，本实施方式中，第三支撑面441设置成使得在第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接时所需的外力小于在第三支撑面441从与第二支撑面433弹性抵接切换到与第一支撑面432弹性抵接时所需的外力。
在使用骨传导扬声机构20时，需要将第三支撑面441从与第一支撑面432弹性抵接切换到与第二支撑面433弹性抵接，而在不使用骨传导扬声机构20时，需要将第三支撑面441从与第二支撑面433弹性抵接切换到与第三支撑面441弹性抵接，根据本实施方式，在用户使用骨传导扬声机构20时所需要施加的力小于不需要使用骨传导扬声机构20所需要施加的力，从而能够在一定程度上方便用户使用眼镜的骨传导扬声机构20的功能。
具体地，请一并参阅图34和图36，在一个应用场景中，在第三支撑面441从与第一支撑面432弹性抵接向与第二支撑面433弹性抵接切换时，连接处434初始接触于第三支撑面441的第一位置4411，在第三支撑面441从与第二支撑面433弹性抵接向与第一支撑面432弹性抵接切换时，连接处434初始接触于第三支撑面441的第二位置4412，其中在垂直于铰链转轴41的中轴线的截面上，第一位置4411与弹性件45和支撑件44的接触点 沿弹性件45的弹性偏置方向上的距离d 1小于第二位置4412与接触点沿弹性偏置方向上的距离d 2。
需要指出的是，第三支撑面441与第一支撑面432弹性抵时，连接处434位于靠近第三支撑面441的一端的位置，而在第三支撑面441与第二支撑面433弹性抵接时，连接处434位于靠近第三支撑面441的另一端的位置。因此，上述的第一位置4411与第二位置4412分别位于靠近第三支撑面441的两端处。也就是说，本实施方式中，支撑件44的第三支撑面441的靠近两端的位置与弹性件45和支撑件44的接触点在弹性件45的弹性偏置方向上的距离不同，且第二位置4412对应的距离小于第一位置4411对应的距离。此时，在第三支撑面441从与第一支撑面432弹性抵接向与第二支撑面433弹性抵接切换时，连接处434初始并未立即抵接第三支撑面441而受到弹性件45的反作用力，而是在切换的过程中逐渐抵接第三支撑面441而受到弹性件45的反作用力；而在第三支撑面441从与第一支撑面432弹性抵接向与第二支撑面433弹性抵接切换时，连接处434初始便抵接第三支撑面441而受到弹性件45的反作用力，或者至少相对于第三支撑面441从与第二支撑面433弹性抵接向与第一支撑面432弹性抵接的切换要早受到弹性件45的反作用力。因此，这种情况下，铰链40在由与第一支撑面432弹性抵接向与第二支撑面433弹性抵接切换时所需要的作用力较小，从而使得用户在使用骨传导扬声机构20时所扳动骨传导扬声机构20所需要施加的力较小，从而方便用户使用。
进一步地，第三支撑面441包括第一子支撑面4413和第二子支撑面4414，其中第一位置4411设置于第一子支撑面4413，第二位置4412设置于第二子支撑面4414。即第一子支撑面4413和第二子支撑面4414分别设置于靠近第三支撑面441的两端的位置。
其中，第二子支撑面4414可以为平面，具体地，在第一支撑面432或第二支撑面433与第三支撑面441弹性抵接时，第二子支撑面4414可与第一支撑面432或第二支撑面433平行。而第一子支撑面4413可以为平面，也可以为弧面，此处不做限定。
进一步地，第一子支撑面4413与第二子支撑面4414不位于同一平面上，第一子支撑面4413相对于第二子支撑面4414倾斜设置，且二者之间的夹角可不大于10°，例如可以为不大于2°、4°、6°、8°、10°等。具体地，第一子支撑面4413朝向远离铰链臂43的方向设置，从而使得在垂直于铰链转轴41的中轴线的截面上，第一位置4411与弹性件45和支撑件44的接触点沿弹性件45的弹性偏置方向上的距离小于第二位置4412与接触点沿弹性偏置方向上的距离。其中，在第一子支撑面4413为弧面而第二子支撑面4414为平面时，第一子支撑面4413与第二子支撑面4414之间的夹角为在二者的相交处与第一子支撑面4413相切的平面与第二子支撑面4414之间的夹角。
请进一步参阅图37，在一实施方式中，铰链座42包括座本体423以及从座本体423凸出且彼此间隔设置的第四凸耳424和第五凸耳425，铰链臂43包括臂本体435以及从臂本体435凸出设置的第六凸耳436，第六凸耳436插入至第四凸耳424和第五凸耳425之间的间隔区域，并通过铰链转轴41与第四凸耳424和第五凸耳425转动连接，第一支撑面432和第二支撑面433设置于第六凸耳436上，支撑件44至少部分设置于间隔区域内且位于第六凸耳436朝向座本体423的一侧，座本体423上设置有与间隔区域连通的容置腔4231，弹性件45设置于容置腔4231内，并将支撑件44朝向第六凸耳436进行弹性偏置。
具体地，第四凸耳424、第五凸耳425和第六凸耳436的对应位置处可分别设置有位于同一轴向上的第一通孔、第二通孔和第三通孔，三个通孔的内径均可不小于铰链转轴41的外径，从而在铰链转轴41穿设于对应的通孔中时，第四凸耳424和第五凸耳425所在的铰链座42能够与第六凸耳436所在的铰链臂43转动连接在一起。
其中，第一支撑面432和第二支撑面433均设置于第六凸耳436上，且平行于铰链转轴41的中轴线，从而使得在铰链臂43绕铰链转轴41相对于铰链座42转动时，使得第一支撑面432和第二支撑面433均可能进入第四凸耳424和第五凸耳425之间的间隔区域。
进一步地，支撑件44位于座本体423的第四凸耳424和第五凸耳425之间，且支撑件44的第三支撑面441朝向第六凸耳436设置。在一个应用场景中，弹性件45完全设置于容置腔4231内，并在朝向第四凸耳424和第五凸耳425之间的间隔区域的一侧与支撑件44接触。在弹性件45处于自然状态时，支撑件44靠近弹性件45的区域至少部分位于容置腔4231内。需要指出的是，支撑件44位于容置腔4231内的部分的形状与容置腔4231匹配，从而使得在弹性件45将支撑件44进行弹性偏置时，支撑件44位于容置腔4231的部分能够在容置腔4231内稳定滑动。
在一个应用场景中，在垂直于铰链座42的长度方向的截面上，容置腔4231的截面面积小于第四凸耳424和第五凸耳425之间的间隔区域的截面面积，支撑件44位于容置腔4231外的区域的形状与间隔区域匹配，从而使得支撑件44在朝向弹性件45一侧移动时，不至于全部进入容置腔4231内。
当然，在其它实施方式中，在垂直于铰链座42的长度方向的截面上，容置腔4231的截面形状也可以与第四凸耳424和第五凸耳425之间的间隔区域相同，此时，支撑件44可完全容置于容置腔4231内，从而使得在支撑件44收到推动作用时，在整个容置腔4231内滑动。
进一步地，铰链座42的第一端面422为第四凸耳424和第五凸耳425的朝向铰链臂43的端面，由臂本体435朝向凸出设置的第六凸耳436位于第四凸耳424和第五凸耳425之间的间隔区域内，从而使得第四凸耳424和第五凸耳425的第一端面422朝向臂本体435设置。在铰链转轴41的中轴线方向的截面上，臂本体435进一步凸出于第六凸耳436从而形成朝向铰链座42的第四凸耳424和第五凸耳425的第二端面431。
本实施方式中，在铰链臂43与铰链座42进行相对转动的过程中，第四凸耳424和第五凸耳425的第一端面422与臂本体435的第二端面431之间的间隙始终大于或小于第二连接线60的直径，从而使得第二连接线60不至于在铰链座42与铰链臂43的相对转动过程中夹入第四凸耳424和第五凸耳425与臂本体435之间，进而减少铰链40对第二连接线60的损伤。
在一个应用场景中，在第四凸耳424和第五凸耳425的第二端面431与臂本体435的第一端面422之间的间隙在铰链臂43与铰链座42进行相对转动过程中始终保持为远大于或远小于第二连接线60的直径，从而进一步减少铰链40对第二连接线60的损伤。
需要指出的是，本实施方中，第一端面422与第二端面431之间的间隙可以为尺寸相同的均匀的间隙，从而均满足上述大于或者小于第二连接线60直径的条件；或者在另一实施方式中，可以仅是两端面靠近第二连接线60的位置处的间隙满足大于或者小于第二连接线60的直径，而两端面的其它位置处的间隙可以无需满足上述条件。
具体地，在一个应用场景中，在垂直于铰链转轴41的中轴线的截面上，第四凸耳424和第五凸耳425朝向铰链臂43的端面和臂本体435朝向铰链座42的端面中的至少一者可采用倒角设置，以使得在铰链臂43与铰链座42进行相对转动过程中二者之间的间隙靠近第二连接线60的位置始终保持为大于第二连接线60的直径。
其中，倒角设置既可以是倒圆角，或者也可以是直接切角均可。
本应用场景中，仅需要将靠近第二连接线60位置处的第四凸耳424和第五凸耳425朝向铰链臂43的端面和臂本体435朝向铰链座42的端面中的至少一者进行倒角设置而使得在铰链臂43与铰链座42进行相对转动过程中不会将第二连接线60夹入两端面之间的间隙中。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
