在一些实施例中，第一传振件1可以由不锈钢材料制成，当其厚度在0.1-0.2mm并且三根第一支杆112的宽度在0.5-1.0mm的时候，能够使得扬声器的低频谐振峰在300-900Hz；当第二振动件第二支杆122的宽度在1.6-2.6mm，厚度在0.8-1.2mm的时候，能够使得扬声器的高频谐振峰在7500-9500Hz。同时，第一传振件1和第二传振件2的结构也不仅限于三根直杆的结构，只要他们的结构能够使得传振片和振动板产生适当的柔度，十字杆、弯曲杆或者其他杆状结构也是适用的。在一些实施例中，通过改变第一传振件1和第二传振件2的材料、厚度，以及调整第一/第二支杆122的宽度等，可以获得扬声器满足不同条件的低频/高频谐振峰。例如，扬声器的低频谐振峰可以在100-1000Hz，优选地，在100-900Hz，更优选地，在200-800Hz，进一步优选地，在300-800Hz，更进一步优选地，在400-700Hz。再例如，扬声器的高频谐振峰可以在4000-10000Hz，优选地，在4000-9500Hz，更优选地，在5000-9000Hz，进一步优选地，在5500-8000Hz，更进一步优选地，在6000-7000Hz。再例如，扬声器的低频谐振峰和高频谐振峰之间的频率差不小5000Hz，优选地，不小于6000Hz，更优选地，不小于7000Hz，进一步优选地，不小于8000Hz，更进一步优选地，不小于10000Hz，更进一步优选地，不小于12000Hz。
当然如果复合振动部件越多则得到的谐振峰越多，在拟合下曲线也会趋于平坦，声音更为宽广。因此，根据实际的应用场景，可以采用多于两个的第一传振件1和第二传振件2等类似部件进行重叠设置。
图4是根据本申请的一些实施例的扬声器复合振动装置的频率响应的示意图。如图4所示，由第一传振件1和第二传振件2构成的复合振动装置产生了两个谐振峰，具体包括谐振峰4001、谐振峰4002。最终可以拟合成图4所示的虚线的频率响应曲线，也就是理想状态下的平坦的频率响应，这些谐振峰范围都可以在耳朵所能听到的频响范围内，这样就拓宽了音响的谐振响应范围，得到了理想的声音。在一些实施例中，通过调节第一传振件1和第二传振件2的尺寸和/或材料等参数，可以改变谐振峰的位置，例如，可以使低频的谐振峰位于频率更低的位置，或者使高频的谐振峰位于频率更高的位置。
在一些实施例中，振动组件104还可以包括线圈。例如，第二传振件2下方可以固定有线圈，线圈的至少一部分可以位于磁路系统内。线圈能够接收电信号，将电信号在磁场的作用下转化为机械振动信号。在一些实施例中，第一传振件1可以与壳体106连接，能够将所述振动信号传递给壳体106。
在一些实施例，当所述扬声器为骨传导扬声器时，壳体106可以将机械振动传递给人体，使人体能够听到声音。壳体106可以构成一个容置空间，磁路组件102和振动组件104可以设置在壳体106内部。在一些实施例中，壳体106的内壁可以和振动组件104直接或者间接相连接，当用户佩戴骨传导扬声器时，壳体106的外壁与用户接触并将振动组件104的机械振动经由骨骼传递到听觉神经，使人体听到声音。
在一些实施例中，壳体106外表面可以具有贴合面。所述贴合面为当用户佩戴扬声器时，扬声机构20的与人体相接触的外表面。当骨传导扬声器能够将贴合面压紧在预设区域(耳屏前端、头骨位置或耳廓背面)，从而有效地将振动信号经由骨骼传递给用户的听觉神经，改善骨传导扬声器的音质。
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，在一些实施例中，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。
例如，可以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5。例如，骨传导耳机可以贴合至耳柄前端，通过皮肤将骨传导耳机产生的振动信号传递到头部硬质骨，再进一步传导至耳蜗，使人体听到声音。
需要指出的是，耳廓为人体外耳的一部分，主要由软骨构成。在一些实施例中，将骨传导扬声器的贴合面贴合至耳廓背面，也可以利用耳廓的软骨传递骨传导声音/振动。
在一些实施例中，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，进而产生相应的空气传导声；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空气传导声产生高频谐振。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，当骨传导扬声器的贴合面贴合耳廓时，骨传导声音/振动的传递路径如图6所示，相比于其他贴合部位的传递路径(例如，图5显示的传递路径)，在传递路径中增加了耳廓软骨传递的环节。
此外，请进一步参阅图7，图7展示了利用数学计算的方法可以计算出骨传导扬声器的扬声机构(例如，扬声机构20)贴合耳廓背面的方案与其他贴合方案(例如，贴合在耳廓前面)传递路径的频域特性。相对于其他贴合方案，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，这表明将扬声机构20的贴合面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，由于扬声机构20的贴合面贴合在耳廓背面，进而使得扬声机构20能够隐藏在耳后而不显现出来以满足用户的不同需求。
在一些实施例中，固定机构可以作用于扬声机构20，使扬声机构20的贴合面能够贴合于用户的耳廓背面的预定区域，提高用户的佩戴体验。进一步地，由于耳轮脚正对的耳廓背面区域较为平坦，适合扬声机构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8和图9。在一些实施例中，预定区域可以为以耳轮脚正对的耳廓背面的一定范围的区域，例如5cm 2、10cm 2、20cm 2、30cm 2等。
在一些实施例中，扬声机构可以设置在固定机构上，通过固定机构使扬声机构固定在预设位置，例如，耳廓背面的区域。在一些实施例中，扬声机构和固定机构之间还可以设置有连接件，通过连接件，扬声机构可以相对固定机构有多个位置状态，实现 扬声机构的位置的调整和变换。在一些实施例中，连接件上可以设置有铰链，并通过铰链实现不同位置的变换。在一些实施例中，铰链可以具有铰链座和铰链臂，铰链臂能够相对铰链座转动连接，在铰链臂相对铰链座转动不同角度时，可以使扬声机构处于不同的位置状态。
在一些实施例中，固定机构可以是眼镜架、帽子、头饰或其他头戴用品中的一种或几种组合。例如，扬声机构可以是两个，分别设置在眼镜腿的两端。又例如，扬声机构可以设置在帽子上，并位于帽子上对应耳廓背面的位置处。下面将以固定机构是眼镜架为例，具体说明固定机构和连接件等扬声器各部件的结构。在一些实施例中，眼镜架可以是近视镜、远视镜、太阳镜，3D眼镜等各种眼镜的眼镜架，具体不做限定。
图10为本申请中的一种实施例所示的扬声器的结构示意图。如图10所示，扬声器具有扬声器机构20、连接件322、铰链40和固定机构10，其中，固定机构10为眼镜架。
眼镜架30可以包括眼镜框31以及眼镜腿32，眼镜腿32可以包括与眼镜框31连接的镜腿主体321以及与镜腿主体321远离眼镜框31的端部连接的连接件322。在一些实施例中，扬声机构20可以设置于连接件322上。
在一些实施例中，连接件322可以用于将扬声机构20与固定机构10进行连接。连接件322可以使扬声机构20位于第一固定位置或第二固定位置。当用户佩戴该扬声器时，第一固定位置可以为扬声机构20远离人体时的固定位置(如图10所示)，第二固定位置可以扬声机构20靠近人体时的固定位置(如图11所示)，连接件322可以使得扬声机构20在第一固定位置和第二固定位置之间转换。
在一些实施例中，当扬声机构20位于第一固定位置时，也可以被认为是扬声器处于非工作状态，即用户佩戴眼镜，但没有使用眼镜的扬声器功能(如听歌)，或者用户没有佩戴眼镜。在一些实施例中，当扬声机构20位于第二固定位置时，也可以被人为是扬声器处于工作状态，即用户佩戴眼镜并使扬声机构20贴在人体预设区域，保持与人体接触的状态。
在一些实施例中，所述第二固定位置时可以使得扬声机构20贴合于用户的耳廓背面。具体的，扬声机构20可以具有与人体相接触的贴合面21，当连接件322处于第二固定位置时，扬声机构20能够以一定压力将贴合面21压紧在耳廓背面的预定区域，从而有效地将振动信号传递给人体。
在一些实施例中，贴合面21可以至少部分为曲面，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，使得扬声机构20与耳廓背面能够充分接触，从而提高扬声机构20通过耳廓背面进行声音/振动的传递的效率。
图12所示为根据本申请一些实施例所示的扬声机构的结构示意图。在一些实施例中，贴合面21可以包括位于中部的平面21a，以及沿平面周向延伸的曲面21b，平面21a和曲面21b可以共同构成朝向耳廓背面凸起的弧面。在一些实施例中，贴合面21的面积不小于0.5cm 2，或不小于1cm 2。由于本实施例中贴合面21面积足够大，能够进一步使得扬声机构20与耳廓背面的接触面积足够大，一方面能够减小扬声机构20的贴合面21施加在用户耳廓背面的压强，减少用户的佩戴负担，提升用户佩戴该扬声器的舒适度；另一方面能够提高声音/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。
在一些实施例中，当扬声机构20处于其中一个固定位置时，可以通过向连接件322施加预设大小的力将扬声机构20切换至另一固定位置。其中，由于需要向连接件322施加超过预设大小的力才能够改变扬声机构20的固定位置，可以避免扬声机构20因为自身重力等原因导致扬声机构20的位置的自动改变，一方面能够使得用户能够准确得定位扬声机构20的位置，一方面能够减少因为扬声机构20抖动而带来的不好的使用体验。
在一些实施例中，扬声机构20相对于镜腿主体321可以具有第一固定位置和第二固定位置，而无中间过渡状态。例如在扬声机构20相对于镜腿主体321处于第一固定位置时，该眼镜可作为正常的眼镜使用(例如，没有使用扬声器功能的眼镜)，此时，用户可手动向连接件322施加大于预设大小的力调整连接件322的位置，连接件322和扬声机构20相对于镜腿主体321发生折叠而使得扬声机构20相对于镜腿主体321处于第二固定位置，使扬声机构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眼镜的扬声器功能，而不会出现介于第一固定位置和第二固定位置之间的其它位置。
当然，在另一些实施例中，扬声机构20相对于镜腿主体321还可具有上述第一固定位置和第二固定位置之外的一个或多个其它固定位置，以满足用户的不同使用需求。例如，扬声机构20还可以具有第三固定位置，当用户不佩戴眼镜时，扬声机构20调整成第三固定位置，然后收纳在眼镜盒或眼镜袋中，更便于携带。
在一些实施例中，连接件322可以具有铰链40，铰链40可以用于实现扬声机构20在第一固定位置和第二固定位置之间的转换。在一些实施例中，铰链可以具有铰链座和铰链臂，铰链臂可以至少具有第一支撑面和第二支撑面，铰链座包括第三支撑面，所述第一支撑面和所述第二支撑面能够分别与所述第三支撑面抵接，以实现所述第一固定位置和所述第二固定位置之间的切换。具体的，连接件322可以与镜腿主体321远离眼镜框31的端部通过铰链40进行铰接。
图13为所示为根据本申请一些实施例所示的扬声器的局部结构示意图；图14所示为根据本申请一些实施例所示的扬声器的局部结构爆炸图。如图13和14所示，在一些实施例中，铰链40可以具有铰链座42和铰链臂43。其中，铰链臂43可以通过转轴41与铰链座42转动连接。参见图21，在一些实施例中，铰链臂43可以至少具有第一支撑面432和第二支撑面433，铰链座42可以包括第三支撑面441，第一支撑面432和第二支撑面433能够分别与第三支撑面441抵接，以实现第一固定位置和第二固定位置之间的切换。
在一些实施例中，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，在其它实施例中，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，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，在另一些实施例中，还可以通过第一插置孔3212与固定件323的过盈配合等方式进行连接从而将铰链座42固定在铰链腔3211内。
在一些实施例中，铰链臂43可以与连接件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之间能够绕转轴41进行转动，且将扬声机构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。
在上述实施例中，镜腿主体321上可以设置有与镜腿主体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。
请继续参阅图13，在一些实施例中，铰链座42上可以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的形状可以与固定件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。
此外，请进一步参阅图15，图15是图13中扬声器局部沿B-B轴线的剖视图。在一些实施例中，在垂直于镜腿主体321的长度方向的截面上，铰链座42的截面形状可以与铰链腔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15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(如柱形、棱形)，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。本实施例中的第一插置孔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。
图16所示为根据本申请另一些实施例所示的扬声器的局部结构示意图。请进一步参阅图16，在一些实施例中，铰链40等可以用于将扬声机构20连接于镜腿主体321远离眼镜框31的端部。
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之间可以存在一定的间隙，即第一端面和第二端面间隙配合，以使得铰链座42和铰链臂43能够绕转轴41进行相对转动。在本实施例中，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。
具体地，请进一步一并参阅图17至图21，在一些实施例中，铰链40的铰链臂43至少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。在一些实施例中，铰链40还可以具有多个支撑面，每个支撑面都可以与第三支撑面进行抵接，实现多个固定位置的转换。
在一些实施例中，在扬声机构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，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，需要的转轴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，在垂直于转轴41的中轴线的截面上若铰链臂43上某一位置与转轴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441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，在本实施例中，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，在其他实施例中，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，如图17和图18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到转轴41的距离大于第一支撑面432到转轴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逐渐靠近转轴41的与第三支撑面441之间的区域，在此过程中，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与转轴41的连线垂直于第三支撑面441时，在垂直于转轴41的中轴线的截面上，转轴41到第三支撑面441的距离等于转轴41到连接处434的距离，此时转轴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(如图20和图21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带动扬声机构20相对于镜腿主体321在第一固定位置和第二固定位置之间进行切换，并在使得扬声机构20在处于第一固定位置时能够贴合于用户的耳廓背面。
在一些实施例中，转轴41到连接处434的距离可以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。
具体的，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，转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离之间的比例不同时，切换过程中产生的跳变的程度不同。
在一些实施例中，在垂直于转轴41的中轴线的截面上，转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离之间的比例介于1.1和1.5之间。具体地，可通过将转轴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，来实现转轴41到连接处434的最大距离大于转轴41到第一支撑面432的最短距离，进而满足上述比例。
需要指出的是，转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离之间的比例过大时，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；而转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离之间的比例过小时，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。本实施例中的将转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离的比例设置为介于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。
在一些实施例中，转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离的比例还可以介于1.2和1.4之间，具体地，转轴41到连接处434的最大距 离与转轴41到第一支撑面432的最短距离的比例还可以为1.1、1.2、1.3、1.4、1.5等，此处不做具体限定。
进一步的，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17和图20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。在一些实施例中，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4312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4312之间的夹角变小时，本实施例中上述转轴41到连接处434的最大距离与转轴41到第一支撑面432的最短距离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，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。
请继续参阅图19，在一些实施例中，在垂直于转轴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可以为钝角。
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。因此，如果第一支撑面432与第二支撑面433为垂直设置，那么当铰链40需要在上述两种状态之间进行切换时，将铰链臂43与铰链座42相对扳动90°即可实现。
在一些实施例中，在垂直于转轴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可以为钝角，从而在铰链40于两种状态之间切换时，所铰链臂43可以与铰链座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，扬声机构20处于第一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扬声机构20的功能时，仅需要将扬声机构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。
在一些实施例中，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。需要说明的是，当该夹角ω 3的角度过大时，铰链臂43和连接于铰链臂43远离铰链座42的端部的扬声机构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；当夹角ω 3的角度过小时，一方面用户需要切换扬声机构20的固定位置，扳动扬声机构20时，所需要扳动的角度过大，用户使用不方便，另一方面，如上述实施例所述，镜腿主体321与铰链40和扬声机构20之间所形成的夹角较小，而难以起到对眼镜的固定的作用，从而使得用户佩戴眼镜时，眼镜容易从用户头部前侧掉落。在一些实施例中，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ω 3的具体角度，以便用户更好的佩戴。
具体地，在一个应用场景中，在垂直于转轴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扬声机构20处于第一固定位置时，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，且在对扬声机构20的两种相对位置进行切换时也无需将铰链40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。
在一些实施例中，第三支撑面441可以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状态的切换会带动扬声机构20相对于镜腿主体321在第一固定位置和第二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扬声机构20和用户不使用扬声机构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。在一些实施例中，当用户从不使用扬声机构20功能切换到使用扬声机构20功能的时需要施加的外力可以大于用户从使用扬声机构20功能切换到不使用扬声机构20功能的时需要施加的外力。
在一些实施例中，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，对应于将扬声机构20由第二固定位置扳动至第一固定位置从而贴合于用户的耳廓背面。
图22所示为根据本申请另一些实施例所示的扬声器的局部结构爆炸图。请进一步参阅图22，在一些实施例中，铰链座42可以包括座本体423以及从座本体423凸出 且彼此间隔设置的第一凸耳424和第二凸耳425，铰链臂43包括臂本体435以及从臂本体435凸出设置的第三凸耳436，第三凸耳436插入至第一凸耳424和第二凸耳425之间的间隔区域，并通过转轴41与第一凸耳424和第二凸耳425转动连接，第一支撑面432和第二支撑面433设置于第三凸耳436上，支撑件44至少部分设置于间隔区域内且位于第三凸耳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朝向第三凸耳436进行弹性偏置。
具体地，第一凸耳424、第二凸耳425和第三凸耳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转轴41的外径，从而在转轴41穿设于对应的通孔中时，第一凸耳424和第二凸耳425所在的铰链座42能够与第三凸耳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均设置于第三凸耳436上，且平行于转轴41的中轴线，从而使得在铰链臂43绕转轴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均可能进入第一凸耳424和第二凸耳425之间的间隔区域。
进一步地，支撑件44位于座本体423的第一凸耳424和第二凸耳425之间，且支撑件44的第三支撑面441朝向第三凸耳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，并在朝向第一凸耳424和第二凸耳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。
在一些实施例中，铰链座42的第一端面422为第一凸耳424和第二凸耳425的朝向铰链臂43的端面，由臂本体435朝向凸出设置的第三凸耳436位于第一凸耳424和第二凸耳425之间的间隔区域内，从而使得第一凸耳424和第二凸耳425的第一端面422朝向臂本体435设置。在转轴41的中轴线方向的截面上，臂本体435进一步凸出于第三凸耳436从而形成朝向铰链座42的第一凸耳424和第二凸耳425的第二端面431。
在一些实施例中，连接件322可以为弹性结构，能够在扬声机构20处于第二固定位置时，提供一定压力将扬声机构20的贴合面21贴在耳廓背面。
其中，所述压力是指在用户使用正常佩戴扬声器(如眼镜)时，贴合面21在垂直贴合面21方向上施加在用户耳朵的压力。制作连接件322的材料的弹性系数不同、以及连接件322的形状、规格等因素，均会影响扬声机构20的贴合面21对用户的耳廓背面施加的压力的大小。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23，在用户正常使用的状态下，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垂直的方向将扬声机构20拉离耳廓背面。取扬声机构20恰与耳廓背面分离时所测得的力作为扬声机构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。
在一些实施例中，连接件322的形状可以根据用户的实际需求进行改变，从而由此产生的压力可以是一个变化的数值。例如用户在佩戴眼镜时，不同的佩戴状态，以及不同的头型的人佩戴，以及个人的佩戴习惯，其所对应的压力的值是不同的。例如，有的用户喜欢更贴合头部，有的用户则需要无触感的佩戴体验(即贴合的压力不容易被感知)，有的用户头部较宽，有的用户较窄。此时，由于连接件322为柔性连接杆，且形状可以调整，从而能够根据佩戴者的不同需求等进行不同程度的变形，以适应不同的情况。
在一个应用场景中，压力的上限可以为1N，该压力上限能够使得扬声机构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，不会出现因扬声器振动造成扬声机构20与耳廓背面脱离的情况。
可选地，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声音/振动，从而使得扬声器有足够大的音量。
具体地，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。
在一些实施例中，铰链40的转轴41的中垂面α、连接件322的对称面β以及扬声机构20贴合耳朵的贴合面21中心点O可以同在一个平面内，或可以在相对平面的预定误差范围内。
其中，铰链40的转轴41的中垂面α可以是指垂直于铰链40的转轴41的轴向且将该铰链40的转轴41对称分割的面，具体请参阅图24。
在一些实施例中，连接件322的对称面β可以是指将连接件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25。
其中，预定误差范围可以根据经验以及连接件322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40的转轴41的中垂面α、连接件322的对称面β以及扬声机构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及扬声机构20发生扭转而导致扬声机构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，进而降低扬声器的音质。当然，铰链40的转轴41的中垂面α、连接件322的对称面β以及扬声机构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，在扬声机构20相对于镜腿主体321处于第一固定位置时，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可以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26所示；连接件322的对称面β与如上述图25中所示相同，此处不再赘述。
容易理解地，在扬声机构20相对于镜腿主体321处于第一固定位置时，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，会影响扬声器通过耳软骨进行声音/振动的传递，进而降低扬声 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，在扬声机构20相对于镜腿主体321处于第一固定位置时，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，在扬声机构20相对于镜腿主体321处于第一固定位置时，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。
在一些实施例中，在扬声机构20相对于镜腿主体321处于第一固定位置时，眼镜框31的对称面λ与连接件322的对称面β之间的夹角可以为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27所示。连接件322的对称面β与上述图25中所示相同，此处不再赘述。
在一些实施例中，上述眼镜框31的对称面λ与连接件322的对称面β之间的夹角可以与用户的头型有关，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，从而容易导致扬声机构20的贴合面21脱离耳廓背面，从而降低扬声机构20的音质，且给用户使用带来不便。
在一些实施例中，在扬声机构20相对于镜腿主体321处于第一固定位置时，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。
请参阅图28，两条眼镜腿32对应的铰链40的转轴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，当用户佩戴眼镜时，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40的转轴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，从而导致眼镜容 易从用户头部松离，进而导致扬声机构20偏离对应耳廓背面的位置；而若距离h 1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。
在一些实施例中，两条眼镜腿32对应的铰链40的转轴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。例如男士的头部较大，因此设计男款的距离h 1可以为115～130mm，女士的头部较小，因此设计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。
请继续参阅图30，在一些实施例中，眼镜框31的对称中心点到两个铰链40的转轴41的中心点的连线的垂直距离h 2可以为105～170mm。
需要指出的是，眼镜框31的对称中心点可以为位于眼镜框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，当该垂直距离h 2较大时，则在用户佩戴眼镜，扬声机构20的贴合面21能够贴合到耳廓背面时，眼镜框31离用户的眼部较远，此时虽然贴合面21贴合耳廓背面，但是眼镜框31离用户的眼部较远，导致用户的眼睛非常不适。而在耳机眼镜框31佩戴合适时，则扬声机构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40的转轴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，例如男士的头部较大，因此设计男款的距离h 2可以为140～160mm，女士的头部较小，因此设计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12和图28，每个铰链40的转轴41的中心点到对应的扬声机构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40的转轴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40的转轴41的中心点到对应的扬声机构20的贴合面21的中心点O之间的距离h 3对应于铰链40的转轴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40的转轴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40的转轴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40的转轴41的中心点到对应的扬声机构20的贴合面21的中心点O之间的距离较大，则扬声机构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40的转轴41的中心点到对应的扬声机构20的贴合面21的中心点O之间的距离较小，则扬声机构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扬声器，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。
图29所示为根据本申请一些实施例所示的连接件的动力机构的模块示意图。如图29所示，在一些实施例中，连接件322可以具有液压传动装置302。通过液压传动装置302提供外力，可以将扬声机构20在第一固定位置和第二固定位置之间进行切换。
在一些实施例中，液压传动装置302可以包括液压缸、液压油、伸缩杆和复位弹簧。当扬声机构20由第一固定位置切换为第二固定位置时，可以驱动液压油进入液压缸，推动伸缩杆伸出，带动铰链臂转动，由第一支撑面切换为第二支撑面与铰链座的第三支撑面抵接，使扬声机构20处于第二固定位置以贴合于用户的耳廓背面。当扬声机构20由第二固定位置切换为第一固定位置时，可以驱动液压油流出液压缸，复位弹簧拉动伸缩杆复位，带动铰链臂由第二支撑面切换为第一支撑面与铰链座的第三支撑面抵接，使扬声机构20处于第一固定位置。
在一些实施例中，液压传动装置302可以辅助用户对扬声机构20的固定位置进行切换。
具体的，在一个应用场景中，液压传动装置302可以包括一个传感器，当用户切换扬声机构20的固定位置，需要扳动扬声机构20，传感器会感应到用户施加在扬声机构20上的作用力，然后对施加的作用力进行判断，若用户施加在扬声机构20的力大于传感器设定的阈值(例如1N、2N、3N等)，此时传感器就会判断用户此时需要切换扬声机构20的固定位置，进而控制液压传动装置302切换扬声机构20的固定位置，而不用用户施加较大的力才能切换扬声机构20的固定位置。一方面，给传感器设定一个阈值，可以防止因为其他的外力(例如不小心的触碰或者挤压等)导致扬声机构20的固定位置发生变化。
在一些实施例中，液压传动装置302也可以自动完成扬声机构20的固定位置切换而无需用户进行手动的位置切换。例如，可以增加一个由用户控制的驱动部件(例如，一个控制按钮)，用户通过该驱动部件可以自行控制液压传动装置302进而对扬声机构20的固定位置进行切换，而不需要用户实际扳动连接件322或者扬声机构20，提高用户体验。在一些实施例中，由用户控制的部件与液压传动装置302连接并且能够控制液压传动装置302，该部件的类型可以根据实际情况而定。
具体的，在一个应用场景中，液压传动装置302可以包括一个液压推动杆，液压推动杆可以设置在连接件322上并与液压传动装置302进行连接。当用户需要在第一固定位置和第二固定位置进行切换的时候，按压液压推动杆，液压推动杆控制液压传动装置302中的液压油是进入液压缸还是流出液压缸，即可实现第一固定位置和第二固定位置的切换。进一步的，连接件322上可以设置有一个容纳液压推动杆的容纳孔，液压推动杆处于正常状态时，至少一部分凸出于容纳孔，当用户按压液压推动杆时，液压推动杆被按压至容纳孔中并控制与其连接的液压传动装置302切换扬声机构20的固定位置。
在另一个应用场景中，液压传动装置302可以包括一个按键。按键可以设置在连接件322上并与液压传动装置302进行连接。当用户需要在第一固定位置和第二固定位置进行切换的时候，按压按键，按键控制与之连接的液压传动装置302中的液压油的流向以实现位置切换功能。可替代地，所述按键可以是一个虚拟按键。该虚拟按键可以是一个与扬声器无线连接的控制设备(例如，手机)上的特定程序。当用户触动该虚拟按键后，控制设备会向扬声器发送特定的指令，控制扬声器上液压传动装置302的运行。
进一步的，液压传动装置302的工作方式，可以根据具体情况而定，例如，当液压传动装置302辅助用户切换时，铰链臂上与第二支撑面相对的一侧可以设置有与液压传动装置302之间连接的液压推杆，液压传动装置304中的伸缩杆可以设置在铰链臂上与第二支撑面相同的一侧，用户在进行位置切换时，转动铰链臂的同时可以带动液压推杆向液压缸移动或远离液压缸移动，从而推动液压油进入或流出液压缸，伸缩杆伸出或复位实现辅助铰链臂的转动。又例如，用户可以通过控制部件驱动液压转动装置302自动完成位置切换，液压推杆可以与控制部件连接，例如液压推杆与控制按键连接或液压推杆直接充当控制部件，用户通过按压液压推杆将液压油推入液压缸，或是通过释放按压推杆使得液压油流出液压缸。再例如，如果通过电信号驱动液压推杆，可以在液压 推杆中设置电磁驱动装置，将电磁驱动装置通过导线连接至扬声器的控制电路，通过接受用户的指令驱动液压推杆运动。
在一些实施例中，液压传动装置302可以在扬声机构20处于第二固定位置时，使得扬声机构20以一定压力贴合在人体上。例如，在液压传动装置302驱动连接件322切换至第二固定位置后，液压传动装置302可以通过控制液压缸内的油压控制伸缩杆的伸出或缩回的长度，从而控制扬声机构20贴合人体的压力。以保证扬声机构能够贴合在人体的预定位置处，同时控制压力使得人体受到长时间按压而不会有不适感。液压传动装置302所提供的压力与前述实施例中使用铰链40时提供的压力作用相似，故不再赘述。
在一些实施例中，连接件322还可以包括压力反馈装置304，用于获取压力。在一些实施例中，压力反馈装置304可以包括扫描仪和压力检测装置(如压力传感器)。其中，当用户佩戴好眼镜时，扫描仪可以对用户的头部结构进行扫描并得到适用于该用户头部结构的压力所需要的数据(例如两耳之间的间距，头部前后两侧的间距等)，当扫描仪获得这些数据之后传输给其他部件。可替代地，压力传感器也可以测量获取此时用户佩戴眼镜时，贴合面21的贴合压力，并将贴合压力的具体数值传输给其他部件，以供对扬声机构20的贴合面与耳廓背面的贴合压力进行调整。
在一些实施例中，连接件322还可以包括压力调节装置306，用于根据压力反馈装置304获取的压力，调节扬声机构20与人体之间的接触压力。
在一些实施例中，压力调节装置306可以具有改变扬声机构20贴合压力的结构(例如流量阀)。
在一个应用场景中，当扫描获取用户头部结构数据并分析出适用于该用户头部结构的压力之后，将该信息传输给压力调节装置306。或者当压力反馈装置304接收到来自压力传感器获取的扬声机构20的贴合面21与耳廓背面之间的贴合压力后，将贴合压力的数值传输给压力调节装置306。压力调节装置306接收到信息后，根据压力，对贴合压力进行调节，从而提高用户的佩戴体验。例如，当贴合压力大于预定压力时，压力调节装置306将减小流量阀的流量，降低贴合压力，当贴合压力小于预定压力时，压力调节装置306将增大流量阀的流量，增大贴合压力，防止佩戴过程中扬声器脱离用户的头部。
扬声器还具有传输电信号的导线。在一些实施例中，扬声器的导线可以隐藏在固定机构、连接件和扬声机构的内部，例如，固定机构中可以具有第一连接线，连接件 中可以具有第二连接线，扬声机构内部可以具有内部导线。控制电路和电池可以设置在眼镜腿内，第一连接线和第二连接线可以分别与控制电路或电池连接，第二连接线可以与扬声机构中的内部导线连接。在一些实施例中，固定机构的转轴处，例如眼镜框和眼镜腿的连接处，可以设置方便走线的通孔，以便于所述第一连接线在该转轴处的走线。
图30所示为根据本申请一些实施例所示的扬声器的局部截面示意图，图31是图30中D部分的放大结构示意图。如图31和30所示，在一些实施例中，扬声器可以进一步包括第一连接线50，眼镜架30可以进一步包括转轴组件33。
在一些实施例中，第一连接线50可以为起机械连接作用或电连接作用的连接线。在本实施例中，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。在一些实施例中，转轴组件33的数量可以为两个，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。
在一些实施例中，第一连接线50通过转轴走线通道331后，一端可以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。
在一些实施例中，转轴组件33沿轴向可以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。
在一些实施例中，转轴走线通道331的内径可以大于第一连接线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31和图32，图32所示为根据本申请一些实施例所示的转轴组件与连接线结构示意图。如图所示，在一些实施例中，转轴组件33可以包括第一转轴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，本实施例中，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。
在一些实施例中，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。
图33所示为根据本申请一些实施例所示的第一转轴的结构示意图。如图33所示，在一些实施例中，走线口3321可以包括第一走线口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。
在一个应用场景中，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32，在一些实施例中，走线口3321可以包括第一走线口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。
在另一个应用场景中，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。
在一些实施例中，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，与上述实施例中类似，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。
而在其它实施例中，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。
其中，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32，在一些实施例中，转轴组件33可以进一步包括与第一转轴332同轴且间隔的第二转轴333。
本实施例中，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，在其他实施例中，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34，图34所示为根据本申请一些实施例所示的扬声器的局部爆炸图。在一些实施例中，眼镜框31可以包括第一凸耳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。
在一些实施例中，眼镜腿32可以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互相靠近的端部可以均与第一凸耳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33，在一些实施例中，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，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。
在一些实施例中，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。本实施例中，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，本实施例中的第二走线口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34、图35和图36，图35所示为根据本申请一些实施例所示的眼镜框与眼镜片的结构示意图，图38所示为根据本申请一些实施例所示的眼镜腿的局部结构示意图。在一些实施例中，第一凸耳311和第二凸耳3201可以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。
在一些实施例中，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，在一些实施例中，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。
本实施例中，第三容置孔3112和第四容置孔32021可以均与第一容置孔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，如上述实施例中所述，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，在一些实施例中，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，本实施例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。
在其它实施例中，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。
请继续参阅图34，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，本实施例中，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。
在一些实施例中，连接件中具有第二连接线。参见前述图16，第二连接线60可以设置在铰链40的外侧。
与扬声机构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。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之间可以存在一定的间隙，以使得铰链座42和铰链臂43能够绕转轴41进行相对转动。在本实施例中，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。
在一些实施例中，第一端面422与第二端面431之间的间隙可以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。
在一些实施例中，第二连接线60进一步延伸，可以与扬声机构的内部导线连接，以实现电信号的输入和输出。
以上对扬声器结构的描述仅仅是具体的示例，不应被视为是唯一可行的实施方案。显然，对于本领域的专业人员来说，在了解扬声器的基本原理后，可能在不背离这一原理的情况下，对实施扬声器的具体方式与步骤进行形式和细节上的各种修正和改变，但是这些修正和改变仍在以上描述的范围之内。例如，扬声器可以包括外壳、连接件322等。连接件322可以连接扬声器组件40与外壳。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述发明披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，本领域技术人员可以理解，本申请的各方面可以通过若干具有可专利性的种类或情况进行说明和描述，包括任何新的和有用的工序、机器、产品或物质的组合或对他们的任何新的和有用的改进。相应地，本申请的各个方面可以完全由硬件执行、可以完全由软件(包括固件、常驻软件、微码等)执行、也可以由硬件和软件组合执行。以上硬件或软件均可被称为“数据块”、“模块”、“引擎”、“单元”、“组件”或“系统”。此外，本申请的各方面可能表现为位于一个或多个计算机可读介质中的计算机产品，该产品包括计算机可读程序编码。
此外，除非权利要求中明确说明，本申请所述处理元素和序列的顺序、数字字母的使用或其他名称的使用，并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、 附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，相应地，在一些实施例中，说明书和权利要求中使用的数值数据均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值数据应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和数据为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
最后，应当理解的是，本申请中所述实施例仅用以说明本申请实施例的原则。其他的变形也可能属于本申请的范围。因此，作为示例而非限制，本申请实施例的替代配置可视为与本申请的教导一致。相应地，本申请的实施例不仅限于本申请明确介绍和描述的实施例。
