在一个应用场景中，第一壳体护套21和第二壳体护套92并不完全包覆整个电路壳体101，例如可以在对应于按键的位置，或者对应于电源接口的位置等开设有外露孔，以将相应的结构露出 而方便用户操作。
其中，第一第一壳体护套21和第二壳体护套92在套装在电路壳体101的外围后，可进一步通过一定的手段将二者固定在电路壳体101上，从而将电路壳体101与对应的壳体护套固定在一起。
具体地，在一些实施例中，第一壳体护套21和第二壳体护套92与主侧壁11对应的内表面上分别一体成型有定位凸块212和定位凸块315，主侧壁11的外表面上分别对应设置有定位凹槽111和定位凹槽112。
其中，定位凸块212设置在靠近开口端211的内侧壁上。其中，定位凸块212可以为环绕第一壳体护套21的内侧壁的环形凸块，或者也可以为间隔设置在第一壳体护套21的内侧壁上的多个凸块等，具体可根据实际需求设置。本实施例中，定位凸块212的数量为两个，分别设置在第一壳体护套21的对应于电路壳体101的两个主侧壁11的内侧壁上；类似地，定位凸块315的数量也对应为两个，分别设置在第二壳体护套92的与于电路壳体101的两个主侧壁11对应的内侧壁上。
具体地，在将第一壳体护套21与第二壳体护套92分别套设在电路壳体101的两侧后，进一步将定位凸块212嵌入定位凹槽111，并将定位凸块315嵌入定位凹槽112，以使得第一壳体护套21的开口端211与第二壳体护套92的开口端911弹性抵接在一起，从而包覆电路壳体101。
进一步地，在一些实施例中，第二壳体护套92的覆盖电路壳体101的端壁13的区域的外侧壁317相对于辅侧壁12倾斜设置。具体地，在用户佩戴时，第二壳体护套92的该外侧壁317的靠近用户头部上侧的一侧到靠近用户头部下侧的一侧沿逐渐远离后挂90的方向倾斜。
其中，定位凸块212和定位凸块315可分别沿开口端211和开口端911呈条状设置，并可相对于辅侧壁12倾斜；进一步地，第一壳体护套21和第二壳体护套92在电路壳体101的主侧壁11上的接合缝也可相对于辅侧壁12倾斜设置。其中定位凸块212和定位凸块315，以及第一壳体护套21和第二壳体护套92在电路壳体101的主侧壁11上的接合缝的倾斜方向均可与第二壳体护套92的覆盖电路壳体101的端壁13的区域的外侧壁317的倾斜方向一致，从而使得扬声器装置在外观上更加一致。
在一个应用场景中，第一壳体护套21和第二壳体护套92中的任意一者对电路壳体101的包覆面积不小于另一者对电路壳体101的包覆面积的二分之一。例如，第一壳体护套21对电路壳体101的包覆面积不小于第二壳体护套92对电路壳体101的包覆面积的二分之一，或者第二壳体护套92对电路壳体101的包覆面积不小于第一壳体护套21对电路壳体101的包覆面积的二分之一。其中，第一壳体护套21对电路壳体101的包覆面积和第二壳体护套92对电路壳体101的包覆面积以及二者之间的比例可以根据需求而设置为其它，例如可以各占一半，此处不做具体限定。
其中，电路壳体101与后挂90可以通过一体成型，或者还可以通过插接、卡接等方式连接在一起。
在一些实施例中，后挂90还包括朝向电路壳体101设置的接插端37，第二壳体护套92套设于至少部分接插端37的外部。具体地，接插端37可注塑于第二弹性金属丝的端部，后挂护套93 可进一步注塑于第二弹性金属丝及部分接插端37的外部，并在接插端37处一体成型第二壳体护套92，从而使得第二壳体护套92进一步套设在接插端37的没有被后挂护套93覆盖的区域的外围。
进一步地，电路壳体101设置有朝向后挂90的接插孔14，其中，该接插孔14可设置在电路壳体101的靠近后挂90的端壁13上，并于该端壁13靠近一辅侧壁12的一侧朝向后挂90延伸形成。
其中，接插端37至少部分插入至接插孔14内。其中，在接插端37的相对两侧分别设置有与接插端37相对于接插孔14的插入方向垂直设置的开槽331，两个开槽331可间隔且对称设置于接插端37的两侧。进一步地，该两个开槽331可均在垂直于插入方向上与接插端37的对应的侧壁连通。
相应地，定义接插孔14的第一侧壁15上设置有与两个开槽331位置对应的第一通孔151。其中，接插孔14的第一侧壁15设置在接插孔14外围，且在佩戴状态下，朝向用户头部下侧。
其中，扬声器装置进一步包括一固定件53，该固定件53包括两条平行设置的插脚531和用于连接插脚531的连接部532。本实施例中，两条插脚531平行设置，连接部532可垂直连接设置于两条插脚531的同一侧，从而形成U型的固定件53。
进一步地，插脚531可从由接插孔14的第一侧壁15的外侧壁经通孔插入至开槽331，进而将连接部532阻挡于接插孔14的外侧，从而实现电路壳体101与后挂90的接插固定。
进一步地，在一些实施例中，定义接插孔14的与第一侧壁15相对的第二侧壁16上进一步设置有与第一通孔151相对的第二通孔161，插脚531进一步经开槽331插入至第二通孔161内。其中，第二侧壁16可以为电路壳体101的靠近接插孔14一侧的辅侧壁12，在扬声器装置处于佩戴状态时，该辅侧壁12朝向用户头部上侧。
在本实施例中，插脚531经第一通孔151插入至开槽331内，并进一步经开槽331插入至第二通孔161内，也就是说插脚531能够将后挂90的接插端37的相对两侧壁以及接插端37完全贯穿并连接于一起，从而能够使得电路壳体101与后挂90之间接插更加稳固。
进一步地，在一些实施例中，接插端37沿接插端相对于接插孔14的插入方向进一步划分为第一接插段332和第二接插段333。在垂直于接插端37相对于接插孔14的插入方向的截面方向上，第一接插段332的截面大于第二接插段333的截面。
其中，后挂护套93具体可注塑在接插端的第一接插段332上，并可于第一接插段332与第二接插段333的连接处一体注塑第二壳体护套92。进一步地，开槽331设置于第二接插段333上，且第二接插段333插入于接插孔14内，而接插端37暴露于接插孔14的外部。
进一步地，在一些实施例中，第一接插段332上设置有沿接插端37相对于接插孔14的插入方向设置的第一走线槽3321，第二接插段333远离第一接插段332的外端面上设置有沿垂直于插入方向延伸并贯通至少一外侧面的第二走线槽3331。具体地，第一走线槽3321设置于第一接插段332的靠近用于定义接插孔14的辅侧壁12的一侧，并沿接插端37相对于接插孔14的插入方向贯通第一接插段332的两端面。第二走线槽3331可贯通第二接插段333的垂直于该第二走线槽3331 的延伸方向的外两侧面。
另外，接插孔14的内侧壁上设置有一端与第一走线槽3321连通，另一端与第二走线槽3331连通的第三走线槽162，该第三走线槽162具体由第二侧壁16的内壁面凹陷而形成。
进一步地，电路壳体101包括设置在壳体内部的内隔壁17，以形成一与接插孔14间隔设置的容置腔18。具体地，电路壳体101的主侧壁11、辅侧壁12及端壁13共同构成一容置空间，该内隔壁17的设置将该容置空间分隔为容置腔18及接插孔14两部分。其中，内隔壁17上进一步设置有一走线孔171，以通过该走线孔171将接插孔14及容置腔18连通。
该扬声器装置进一步设置有后挂导线94，该后挂导线94经过后挂90，且两端分别与控制电路和电池连接。具体地，该后挂导线94由后挂90依次经过第一走线槽3321、第三走线槽162及第二走线槽3331，并穿过走线孔171而进入容置腔18，以与控制电路或电池连接。
需要注意的是，以上对扬声器装置的耳机芯壳体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，在了解扬声器装置的耳机芯壳体的基本原理后，可能在不背离这一原理的情况下，对实施扬声器装置的耳机芯壳体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，电路壳体与后挂可以通过一体成型。诸如此类的变形，均在本申请的保护范围之内。
在一些实施例中，本申请中的耳挂20可以是耳机、近视镜、远视镜、太阳镜、3D扬声器装置等各种扬声器装置的耳挂，具体不做限定。在一些实施例中，功能件80(即扬声器组件83)可以通过铰链组件122与耳挂20连接在一起，使扬声器装置进一步具有一些其它功能的组件或构件。
进一步地，如前述实施例所述，扬声器组件83可以包括耳机芯。其中，耳机芯和耳挂20可以通过铰链连接，铰链设置在耳挂20上靠近耳机芯一端。
图5-图18是本申请一些实施例提供的铰链组件的结构示意图，图5是本申请一些实施例提供的铰链组件的结构示意图，图6是本申请一些实施例提供的铰链组件的爆炸结构示意图。在一些实施例中，本申请铰链组件122可用于本申请实施例中的扬声器装置当中。
本申请中，铰链组件122包括铰链30，铰链30是用来连接两个固体并允许两者之间做相对转动的结构。
具体地，本实施例中的铰链组件122在用于上述扬声器装置实施例中时，铰链组件122设置于耳挂20远离电路壳体101的端部，并进一步通过铰链30将功能件80连接至耳挂20远离电路壳体101的端部。
在一些实施例中，铰链组件122还包括杆状件40和固定件50。在一些实施例中，铰链30可以包括铰链座31以及铰链臂32，在一些实施例中，铰链臂32通过转轴33与铰链座31转动连接。容易理解地，铰链座31与铰链臂32可分别连接在需要转动连接的两个构件上，以使得两个构件通过铰链30的转轴33转动连接在一起。
在一些实施例中，铰链30的铰链座31连接设置在杆状件40上。在一些实施例中，杆状件40可以是通过铰链30转动连接的两个构件中的一个的部分结构或者整体结构，或者也可以是需要 转动连接的两个构件中的一个与铰链30进行连接的连接结构。本实施例中的铰链组件122在用于扬声器装置时，杆状件40可以为扬声器装置的耳挂20的至少一部分，例如可以是耳挂20的全部，或者是耳挂20远离电路壳体101的一端的一部分，进而通过该部分耳挂20，将铰链30设置于耳挂20远离电路壳体101的端部。
具体地，杆状件40沿长度方向设置有与杆状件40的端面连通的铰链腔41，杆状件40的侧壁上设置有与铰链腔41连通的第一插置孔42，铰链座31的远离铰链臂32的一端从杆状件40的端面插入至铰链腔41，并由插置在第一插置孔42内的固定件50固定在铰链腔41内。
本实施例中，铰链腔41连通耳挂20远离电路壳体101的端部的端面，从而使得铰链座31插入至铰链腔41内而将铰链30与耳挂20连接。
在一些实施例中，可在杆状件40成型过程中形成铰链腔41，例如，杆状件40的材质可以为橡胶或者塑料等，此时可通过注塑形成铰链腔41。铰链腔41的形状与铰链座31匹配，以使得铰链座31能够容置于铰链腔41内。在本实施例中，耳挂20沿长度方向可以为长直杆状，对应地，杆状件40则可以为沿长度方向的直杆，铰链腔41设置于直杆中，进一步地，铰链座31与铰链腔41匹配以容置于铰链腔41内进而实现铰链30的安装。当然，在其它实施例中，杆状件40也可以为弧形杆等其它形状。
另外，第一插置孔42也可由杆状件40在成型过程中形成，或者在成型后进一步通过钻孔等方法在杆状件的侧壁上形成。具体地，本实施例中，第一插置孔42的形状可以为圆形，在其它实施例中还可以为方形、三角形等其它形状。固定件50的形状与第一插置孔42匹配，以使得固定件50能够从杆状件40的外部插入第一插置孔42，并进而通过抵紧铰链座31的侧壁的方式，或者进一步穿透铰链座31的外壁以插接的方式等将铰链座31固定在铰链腔41内。具体地，可以在第一插置孔42的内壁与固定件50的外壁上设置匹配的螺纹，以使得固定件50能够通过螺接的方式与第一插置孔42连接以进一步将铰链座31固定在铰链腔41内。当然，也可以通过其它方式，例如通过第一插置孔42与固定件50的过盈配合等方式进行连接。
进一步地，铰链臂32还可与其它构件连接，从而使得该构件在于铰链臂32连接后，进一步通过将铰链座31装设在杆状件40的铰链腔41内从而与杆状件40或者与杆状件40连接的其它构件之间能够绕转轴33进行转动。例如，铰链组件122在应用于上述扬声器装置中时，功能件80(例如扬声器组件83)连接设置在铰链臂32远离铰链座31一端，从而通过铰链30连接在耳挂20远离电路壳体101的端部。
上述方式中，杆状件40上设置有与该杆状件40的端面连通的铰链腔41，铰链30通过将铰链座31容置于该铰链腔41内，并进一步将固定件50通过第一插置孔42穿透杆状件40的侧壁从而将容置于铰链腔41内的铰链座31固定在铰链腔41内，从而能够实现铰链30相对于杆状件40可拆装，以方便铰链30或者杆状件40的更换。在应用于本申请上述扬声器装置实施例中的扬声器装置当中时，能够实现铰链30与功能件80相对于耳挂20可拆装，从而在功能件80或后挂90、耳挂20等损坏时，便于进行更换。
进一步地，请继续参阅图6，在一些实施例中，铰链座31上设置有与第一插置孔42对应的第二插置孔311，固定件50进一步插置于第二插置孔311内。
具体地，第二插置孔311的形状与固定件50匹配，以使得固定件50在穿过第一插置孔42后，进一步插入第二插置孔311中以将铰链座31固定，从而减少铰链座31在铰链腔41内的晃动，使得铰链30固定得更加牢固。具体地，与第一插置孔42和固定件50的连接方式相似，第二插置孔311的内侧壁上可设置有与固定件50对应的外壁上互相匹配的螺纹，以使得固定件50与铰链座31螺接在一起；或者，第二插置孔311的内壁与固定件50的对应接触的位置处的外侧壁均为平滑的面，固定件50与第二插置孔311过盈配合，此处不做具体限定。
进一步地，第二插置孔311还可贯穿铰链座31的两侧边设置，从而使得固定件50能够进一步穿透整个铰链座31，以将铰链座31更加牢固得固定在铰链腔41内。
请进一步参阅图7，图7是图5中铰链组件沿A-A轴线的剖视图。本实施例中，在垂直于杆状件40的长度方向的截面上，铰链座31的截面形状与铰链腔41的截面形状相匹配，以使得在插入后铰链座31与杆状件40之间形成密封配合。
在一些实施例中，在图7中提供的截面上，铰链座31的截面形状和铰链腔41的截面形状可以为任意形状，只要能够使得铰链座31从杆状件40的远离铰链臂32的端面插入至该铰链腔41中即可。进一步地，第一插置孔42设置在铰链腔41的侧壁上，并贯通铰链腔41的侧壁与铰链腔41连通。
在一个应用场景中，铰链座31的截面形状和铰链腔41的截面形状均呈矩形设置，第一插置孔42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31外侧壁的棱角或铰链腔41的内侧壁的角倒圆角设置，使得铰链座31与铰链腔41的接触更加平滑，从而使得铰链座31能够顺利得插入至铰链腔41内。
需要进一步指出的是，在铰链30装配前，铰链腔41内存储有一定量的气体，因此若铰链腔41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41内的气体难以排出而不利于铰链座31插入，从而影响装配。本实施例中的第一插置孔42贯通铰链腔41的侧壁而与铰链腔41连通，能够在装配过程中辅助将内部的气体通过铰链腔41由第一插置孔42排出，从而有助于铰链30的正常装配。
请进一步参阅图8，图8是本申请一些实施例提供的铰链组件的结构示意图。本申请铰链组件122实施例中，铰链组件122进一步包括设置于铰链30外侧的连接线36。
在一些实施例中，连接线36可以为具有电性连接作用和/或机械连接作用的连接线36。在应用于本申请上述扬声器装置实施例中的扬声器装置当中时，铰链组件122用于将功能件80连接于耳挂20远离电路壳体101的端部，而与功能件80相关的控制电路等可设置于耳挂20当中，此时，需要连接线36将功能件80与耳挂20中的控制电路等电连接在一起。具体地，连接线36可位于铰链座31和铰链臂32的一侧，与铰链30设置于同一容置空间当中。
进一步地，铰链座31包括第一端面312，铰链臂32具有与第一端面312相对设置的第二端面321，容易理解地，第一端面312和第二端面321之间存在一定的间隙，以使得铰链座31和铰链臂32能够绕转轴33进行相对转动。本实施例中，在铰链臂32与铰链座31进行相对转动过程中，第一端面312与第二端面321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。
而本实施例中，第一端面312与第二端面321之间的间隙始终保持为大于或小于连接线36的直径，从而使得位于铰链30外侧的连接线36不至于在铰链座31与铰链臂32的相对转动过程中夹入第一端面312与第二端面321之间的间隙中，进而减少铰链对连接线36的损伤。具体地，第一端面312与第二端面321之间的间隙在铰链臂32与铰链座31进行相对转动过程中与连接线36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。
请一并参阅图5、图9至图12，图9是本申请一些实施例提供的铰链组件中保护套管的原始状态图，图10是本申请一些实施例提供的铰链组件中保护套管的原始状态的局部截面图，图11是本申请一些实施例提供的铰链组件中保护套管的弯折状态图，图12是本申请一些实施例提供的铰链组件中保护套管的弯折状态的局部截面图。本实施例中，铰链组件122还可进一步包括保护套管70。
具体地，该保护套管70套设在铰链30的外围，并随铰链30发生弯折，在一些实施例中，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，在一些实施例中，环状凸脊部71的管壁厚度大于环状连接部72的管壁厚度。
在一些实施例中，保护套管70的长度方向与铰链30的长度方向一致，保护套管70具体可沿铰链座31和铰链臂32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。
进一步地，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。
在进一步地，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。本实施例中，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30的铰链座31和铰链臂32之间绕转轴33相对转动时，铰链座31和铰链臂32之间的角度发生变化，从而使得保护套管70发生弯折，如图11和图12中所示。具体地，在保护套管70随铰链30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。
本实施例中，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30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30的铰链座31和铰链臂32仅能够绕转轴33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。
在一些实施例中，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。
在一些实施例中，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，本实施例中，铰链座31和铰链臂32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。本实施例中，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。本实施例中，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。
在一些实施例中，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，本实施例中的凹槽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，本实施例中，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711。在一些实施例中，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，在本实施例中的铰链组件122应用于本申请扬声器装置实施例中的扬声器装置当中时，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耳挂20以及功能件80连接在一起。在一个应用场景中，保护套管70还可以为扬声器装置中的其它结构如一些部件的保护盖层等一体成型，从而使得扬声器装置更加封闭、一体。
需要指出的是，本申请实施例中的铰链组件122不仅仅可以用于本申请实施例中的扬声器装置，还可以用于其它装置当中，而且铰链组件122还可以包括除了上述杆状件40、固定件50、连接线36、保护套管70等之外的其它与铰链30相关联的构件以实现相应的功能。
具体地，请进一步一并参阅图13至图17，图13是本申请一些实施例提供的扬声器装置的局部剖面图，图14是图13中A部分的放大图，图15是图14中B部分在由第一支撑面与第三支撑面抵接向第二支撑面与第三支撑面抵接转变而使得第一支撑面与第二支撑面的连接处与第三支撑面初始接触时的放大图，图16是本申请一些实施例提供的铰链的局部剖面图，图17是图16中C部分的放大图。需要指出的是，本申请实施例中的铰链30可用于本申请实施例中的扬声器装置当中，也可用于本申请实施例中的铰链组件122，还可以应用于其它装置当中，此处不做具体限定。
本实施例中，铰链30的铰链臂32具有彼此连接的第一支撑面322和第二支撑面323。
铰链30还包括支撑件34和弹性件35。支撑件34活动设置于铰链座31上，且具有第三支撑面341，弹性件35用于将支撑件34朝向铰链臂32进行弹性偏置，以使得第三支撑面341能够分别弹性抵接于第一支撑面322和第二支撑面323上。
在一些实施例中，在铰链臂32受到外力作用而相对铰链座31进行转动时，由第一支撑面322和第二支撑面323的连接处324推动支撑件34克服弹性件35的弹性偏置而反向移动，进而使 得第三支撑面341从与第一支撑面322和第二支撑面323中的一者弹性抵接切换到与第一支撑面322和第二支撑面323中的另一者弹性抵接。
在一个应用场景中，支撑件34连接设置在弹性件35朝向铰链臂32的一端，且使得第三支撑面341朝向铰链臂32一侧，在铰链臂32受到外力作用而绕转轴33相对铰链座31转动的过程中，能够推动第三支撑面341而使得支撑件34压迫弹性件35，并进一步在弹性件35的作用下发生弹性偏置。当然，支撑件34也可以与弹性件35不连接，而仅仅是抵接在支撑件34的一侧，只要能够使得支撑件34实现上述弹性偏置即可。
在一些实施例中，第一支撑面322和第二支撑面323分别为铰链臂32的相邻的且至少部分与转轴33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32相对铰链座31转动时，第一支撑面322和第二支撑面323随铰链臂32围绕转轴33发生转动，从而使得铰链臂32的不同侧面朝向铰链座31，进而使得铰链臂32相对于铰链座31能够具有不同的相对位置关系。
另外，弹性件35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35可以为弹簧，弹簧的一端抵接支撑件34，在支撑件34的第三支撑面341受到朝向弹性件35的推动作用时，弹性件35反抗支撑件34并发生压缩从而为支撑件34的第三支撑面341所朝向的方向上提供空间，以使得在转轴33的相对位置不变时，仍有足够的空间使得铰链臂32不同的侧面转动至转轴33与第三支撑面341之间。
具体地，在铰链臂32相对于铰链座31转动时，转轴33的相对位置不发生改变，铰链臂32与铰链座31的第三支撑面341的接触位置发生变化，而由于铰链臂32的不同的位置到转轴33的距离不同，因此，在铰链臂32的不同的位置如第一支撑面322和第二支撑面323的不同位置与第三支撑面341接触时，所述需要的转轴33到铰链臂32与第三支撑面341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35压缩而提供的空间可能是有限的。因此，在铰链臂32相对于铰链座31转动的过程中，在垂直于转轴33的中轴线的截面上若铰链臂32上某一位置与转轴33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32继续转动，从而使得铰链臂32和铰链座31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32与铰链座31之间绕转轴33相对转动的过程中，仅有第一支撑面322与第二支撑面323以及第一支撑面322与第二支撑面323的连接处324所对应的区域能够与第三支撑面341抵接。
进一步地，本实施例中，第一支撑面322和第二支撑面323可以均为平面，转轴33到二者的连接处324的距离均大于转轴33到第一支撑面322的距离和到第二支撑面323的距离，铰链30可具有第三支撑面341抵接于第一支撑面322，以及第三支撑面341抵接于第二支撑面323两种相对稳定的状态。
当然，在本实施例中，第一支撑面322和第二支撑面323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32和铰链座31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32上还可以设置其它更多的支撑 面，以在铰链臂32受到外力而绕转轴33与铰链座31之间发生相对转动时，通过铰链臂32上不同的支撑面与第三支撑面341发生弹性抵接而使得铰链臂32与铰链座31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322与支撑件34的第三支撑面341抵接为例，具体如图14和图15中所示。此时弹性件35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30受到外力作用而使得铰链臂32绕转轴33与铰链座31发生相对转动以使得第二支撑面323逐渐靠近第三支撑面341时，第一支撑面322和第二支撑面323的连接处324与第三支撑面341接触，由于连接处324到转轴33的距离大于第一支撑面322到转轴33的距离，从而使得连接处324抵接支撑件34并推动支撑件34移动朝弹性件35的方向移动，进而使得弹性件35克服推力而产生压缩。且在铰链臂32进一步受力时，连接处324逐渐靠近转轴33的与第三支撑面341之间的区域，在此过程中，转轴33到第三支撑面341之间的距离逐渐增大；容易理解地，在连接处324与转轴33的连线垂直于第三支撑面341时，在垂直于转轴33的中轴线的截面上，转轴33到第三支撑面341的距离等于转轴33到连接处324的距离，此时转轴33距离第三支撑面341最远；而在此时，若继续对铰链30施力，则转轴33到第三支撑面341的距离将会逐渐变小，从而所需要的弹性件35压缩的空间减小，并进而使得弹性件35逐渐释放弹力而回复，直到连接处324离开第三支撑面341而使得第二支撑面323与第三支撑面341抵接，从而实现从第一支撑面322与第三支撑面341抵接到第二支撑面323与第三支撑面341抵接之间的切换。
同样地，在初始状态为第二支撑面323与支撑件34的第三支撑面341抵接而向第一支撑面322与支撑件34的第三支撑面341抵接转换的过程(具体如图16和图17中所示)与上述过程类似。
需要指出的是，本实施例中的铰链30可应用于本申请实施例中的铰链组件122当中。在一个实施例中，功能件80可以为扬声器组件83。在一些实施例中，在第三支撑面341从与第一支撑面322和第二支撑面323中的一者弹性抵接切换到与第一支撑面322和第二支撑面323中的另一者弹性抵接时，铰链组件122带动扬声器组件83相对于耳挂20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，并在扬声器组件83处于第一相对固定位置时能够贴合于用户的耳廓背面。其中，耳廓为外耳的一部分，主要由软骨构成。在一些实施例中，扬声器组件83可以为骨传导扬声器组件83，通过将扬声器组件83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。将扬声器组件83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。
需要指出的是，转轴33到连接处324的距离均大于到第一支撑面322和第二支撑面323的垂直距离，从而使得在第三支撑面341从与第一支撑面322和第二支撑面323中的一者弹性抵接切换到与第一支撑面322和第二支撑面323中的另一者弹性抵接的过程中铰链30的状态发生一定程度的跳变。
以第一支撑面322与第三支撑面341弹性抵接切换到第二支撑面323与第三支撑面341弹 性抵接为例，转轴33到连接处324的最大距离h1与转轴33到第一支撑面322的最短距离h2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33的中轴线的截面上，转轴33到连接处324的最大距离h1与转轴33到第一支撑面322的最短距离h2之间的比例介于1.1和1.5之间。
具体地，可以通过将转轴33远离第二支撑面323而靠近与第二支撑面323相对的铰链臂32的一侧面设置，来实现转轴33到连接处324的最大距离h1大于转轴33到第一支撑面322的最短距离h2，进而满足上述比例。
需要指出的是，h1与h2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322与第三支撑面341弹性抵接切换到第二支撑面323与第三支撑面341弹性抵接，从而在一定程度上为使用带来不便；而h1与h2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30时没有明显的触感，从而也会带来不便。本实施例中的将h1与h2的比例设置为介于1.1和1.5之间，能够使得第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时，铰链30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30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30的状态。
在一个应用场景中，h1与h2的比例还可以介于1.2和1.4之间，具体地，h1与h2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322与第二支撑面323在铰链臂32上的位置的设置会影响第三支撑面341与第一支撑面322或第二支撑面323中的一者抵接时铰链臂32与铰链座31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322与第二支撑面323在铰链臂32上的位置进行不同的设置。在一些实施例中，铰链臂32与铰链座31之间的夹角具体如图12和图15所示，ω 1为第三支撑面341与第一支撑面322抵接时铰链臂32与铰链座31之间的夹角，ω 2为第三支撑面341与第二支撑面323抵接时铰链臂32与铰链座31之间的夹角。在一些实施例中，铰链臂32与铰链座31均具有一定的长度，铰链臂32设置在铰链座31的长度方向上的端部一侧，第一支撑面322设置在铰链臂32长度方向上靠近铰链座31的端部，而第二支撑面323设置在铰链臂32宽度方向上的一端，且均平行于转轴33的中轴线设置。此时，当第三支撑面341与第一支撑面322弹性抵接时，铰链臂32与铰链座31之间的夹角最大，而在第三支撑面341与第二支撑面323弹性抵接时，铰链臂32与铰链座31之间的夹角最小，从而在第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时，铰链座31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341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时对铰链臂32所施加的力的方向与铰链臂32自身重力的方向一致，那么在该状态的切换会使得铰链座31与铰链臂12之间的夹角变小时，本实施例中上述h1与h2之间的比例的设置还可以使得在第三支撑面341与第一支撑面322弹性抵接时，铰链臂32不会或者难以因自身重力而自发得减小其与铰链座31之间的角度。
在一些实施例中，请参阅图15，在垂直于转轴33的中轴线的截面上，第一支撑面322和第二支撑面323之间的夹角ω 3为钝角。
在一些实施例中，铰链30在由第一支撑面322与第三支撑面341弹性抵接的状态向第二支撑面323与第三支撑面341弹性抵接的状态切换时，第一支撑面322和第二支撑面323之间的夹角ω 3越小，则状态切换时铰链座31和铰链臂32之间相对需要转动的角度越大，也就是说，在铰链座31固定不动时，用户需要将铰链臂32扳动较大的角度才能够对铰链30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32具有一定的长度，且第一支撑面322设置于铰链臂32的长度方向上的一端，而第二支撑面323与第一支撑面322相邻设置于铰链臂32的宽度方向上。通常情况下，第一支撑面322与第二支撑面323垂直设置，此时，在铰链30在上述两种状态之间进行切换时，需要将铰链臂32与铰链座31相对扳动90°。
而本实施例中，在垂直于转轴33的中轴线的截面上，第一支撑面322和第二支撑面323之间的夹角ω 3为钝角，从而在铰链30于两种状态之间切换时，所铰链臂32与铰链座31所需要相对扳动的角度小于90°，从而能够在一定程度上为用户提供便利。
具体地，在本实施例中的铰链30用于本申请扬声器装置实施例中时，铰链30用于连接耳挂20和扬声器组件83。在一些实施例中，扬声器组件83可以为骨传导扬声器组件83。例如，在铰链30处于第二支撑面323与第三支撑面341弹性抵接的第二状态时，扬声器组件83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扬声器装置的扬声器组件83的功能时，仅需要将扬声器组件83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30处于第一支撑面322与第三支撑面341弹性抵接的第一状态时，铰链臂32和连接的扬声器组件83形成一定的角度，从而在用户佩戴扬声器装置时，铰链臂32和连接的扬声器组件83能够位于用户耳后且朝向用户耳朵的方向设置，从而能够对扬声器装置起到一定的阻拦、固定作用，不易从用户头部掉落。
需要指出的是，第一支撑面322和第二支撑面323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32和连接于铰链臂32远离铰链座31的端部的功能件80与铰链座31之间的夹角将较小，从而在用户佩戴时，铰链臂32与功能件80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，一方面用户在扳动扬声器组件83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，耳挂20与铰链30和扬声器组件83之间所形成的夹角较小而难以起到对扬声器装置的阻拦、固定的作用，从而使得用户佩戴扬声器装置时，扬声器装置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322和第二支撑面323之间的夹角的具体角度。
具体地，在一个应用场景中，在垂直于转轴33的中轴线的截面上，第一支撑面322和第二支撑面323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扬声器装置且扬声器组件83处于第一相对固定位置时，扬声器组件83不会过于靠近用户耳朵而对用户耳朵造成不适，且在对扬声器组件83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。
在一些实施例中，在第三支撑面341从与第一支撑面322和第二支撑面323中的一者弹性抵接切换到与第一支撑面322和第二支撑面323中的另一者弹性抵接的过程当中，第一支撑面322和第二支撑面323之间的连接处324抵接第三支撑面341，并推动支撑件34克服弹性件35的弹性偏置而反向移动。以切换前第三支撑面341与第一支撑面322弹性抵接为例，在初始切换时，第一支撑面322逐渐远离第三支撑面341的同时，连接处324逐渐抵接第三支撑面341，并在切换过程中，由第三支撑面341的一侧滑动至第三支撑面341的另一侧，最后进一步过渡至由第二支撑面323与第三支撑面341弹性抵接。在状态切换过程中，连接处324始终与第三支撑面341抵接而相互作用，而连接处324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322与第二支撑面323之间线连接，那么，连接处324具有较为尖锐的角度，从而在用户扳动铰链座31和/或铰链臂32以进行铰链30的状态切换过程中，一方面，在连接处324与第三支撑面341抵接与连接处324与第一支撑面322和第二支撑面323抵接进行切换时，缓冲较小，切换突兀，从而扳动铰链30的手感差；另一方面，连接处324较为尖锐，会在反复的切换过程中对第三支撑面341造成一定的磨损。
而本申请一些实施例中，在垂直于转轴33的中轴线的截面上，连接处324呈弧形设置。从而使得第一支撑面322与第二支撑面323的连接为弧面连接，进而在铰链30的状态切换的过程当中，与第三支撑面341抵接的连接处324较为平滑，从而用户扳动铰链30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341的损伤。
具体地，在一些实施例中，连接处324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。本实施例中圆弧的曲率介于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，在本实施例中的铰链30应用于上述实施例中的扬声器装置时，圆弧设置的连接处324的曲率能够使得用户在扳动铰链30以使得扬声器装置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。
在一些实施例中，第三支撑面341设置成使得在第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时所需的外力不同于在第三支撑面341从与第二支撑面323弹性抵接切换到与第一支撑面322弹性抵接时所需的外力。
需要指出的是，在具体的使用场景当中，铰链30不同的状态所对应的铰链30、或者铰链30所连接的结构的功能不同，或者由于铰链30设置的位置问题，而使得某一种状态向另一种状态进行切换时不便于用户施力等原因，而在用户对铰链30的状态进行切换时需要在扳动铰链30的力度上进行区分，以方便用户施力，或者为用户区分两种铰链状态提供直观的感受等。
具体地，在本实施例中的铰链30应用于上述扬声器装置中时，铰链30状态的切换会带动扬声器组件83相对于耳挂20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扬声器组件83和用户不使用扬声器组件83两种情况，而用户在佩戴扬声器装置时，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，在一些实施例中，当第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时，对应于将扬声器组件83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，本实施例中，第三支撑面341设置成使得在第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接时所需的外力小于在第三支撑面341从与第二支撑面323弹性抵接切换到与第一支撑面322弹性抵接时所需的外力。
需要指出的是，在应用于上述扬声器装置时，在使用扬声器组件83时，需要将第三支撑面341从与第一支撑面322弹性抵接切换到与第二支撑面323弹性抵接，而在不使用扬声器组件83时，需要将第三支撑面341从与第二支撑面323弹性抵接切换到与第三支撑面341弹性抵接，根据本实施例，在用户使用扬声器组件83时所需要施加的力小于不需要使用扬声器组件83所需要施加的力，从而能够在一定程度上方便用户使用扬声器装置的扬声器组件83的功能。
具体地，请一并参阅图15和图17，在一个应用场景中，在第三支撑面341从与第一支撑面322弹性抵接向与第二支撑面323弹性抵接切换时，连接处324初始接触于第三支撑面341的第一位置3411，在第三支撑面341从与第二支撑面323弹性抵接向与第一支撑面322弹性抵接切换时，连接处324初始接触于第三支撑面341的第二位置3412，在一些实施例中，在垂直于转轴33的中轴线的截面上，第一位置3411与弹性件35和支撑件34的接触点沿弹性件35的弹性偏置方向上的距离d 1小于第二位置3412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341与第一支撑面322弹性抵时，连接处324位于靠近第三支撑面341的一端的位置，而在第三支撑面341与第二支撑面323弹性抵接时，连接处324位于靠近第三支撑面341的另一端的位置。因此，上述的第一位置3411与第二位置3412分别位于靠近第三支撑面341的两端处。也就是说，本实施例中，支撑件34的第三支撑面341的靠近两端的位置与弹性件35和支撑件34的接触点在弹性件35的弹性偏置方向上的距离不同，且第二位置3412对应的距离小于第一位置3411对应的距离。此时，在第三支撑面341从与第一支撑面322弹性抵接向与第二支撑面323弹性抵接切换时，连接处324初始并未立即抵接第三支撑面341而受到弹性件35的反作用力，而是在切换的过程中逐渐抵接第三支撑面341而受到弹性件35的反作用力；而在第三支撑面341从与第一支撑面322弹性抵接向与第二支撑面323弹性抵接切换时，连接处324初始便抵接第三支撑面341而受到弹性件35的反作用力，或者至少相对于第三支撑面341从与第二支撑面323弹性抵接向与第一支撑面322弹性抵接的切换要早受到弹性件35的反作用力。因此，这种情况下，铰链30在由与第一支撑面322弹性抵接向与第二支撑面323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扬声器组件83时所扳动扬声器组件83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341包括第一子支撑面3413和第二子支撑面3414，在一些实施例中，第一位置3411设置于第一子支撑面3413，第二位置3412设置于第二子支撑面3414。即第一子支撑面3413和第二子支撑面3414分别设置于靠近第三支撑面341的两端的位置。
在一些实施例中，第二子支撑面3414可以为平面，具体地，在第一支撑面322或第二支撑面323与第三支撑面341弹性抵接时，第二子支撑面3414可与第一支撑面322或第二支撑面323平行。而第一子支撑面3413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3413与第二子支撑面3414不位于同一平面上，第一子支撑面3413相对于第二子支撑面3414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3413朝向远离铰链臂32的方向设置，从而使得在垂直于转轴33的中轴线的截面上，第一位置3411与弹性件35和支撑件34的接触点沿弹性件35的弹性偏置方向上的距离小于第二位置3412与接触点沿弹性偏置方向上的距离。在一些实施例中，在第一子支撑面3413为弧面而第二子支撑面3414为平面时，第一子支撑面3413与第二子支撑面3414之间的夹角为在二者的相交处与第一子支撑面3413相切的平面与第二子支撑面3414之间的夹角。
请进一步参阅图18，图18是本申请一些实施例提供的铰链的爆炸结构图。本实施例中，铰链座31包括座本体313以及从座本体313凸出且彼此间隔设置的第一凸耳314和第二凸耳316，铰链臂32包括臂本体325以及从臂本体325凸出设置的第三凸耳326，第三凸耳326插入至第一凸耳314和第二凸耳316之间的间隔区域，并通过转轴33与第一凸耳314和第二凸耳316转动连接，第一支撑面322和第二支撑面323设置于第三凸耳326上，支撑件34至少部分设置于间隔区域内且位于第三凸耳326朝向座本体313的一侧，座本体313上设置有与间隔区域连通的容置腔3121，弹性件35设置于容置腔3121内，并将支撑件34朝向第三凸耳326进行弹性偏置。
具体地，第一凸耳314、第二凸耳316和第三凸耳326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33的外径，从而在转轴33穿设于对应的通孔中时，第一凸耳314和第二凸耳316所在的铰链座31能够与第三凸耳326所在的铰链臂32转动连接在一起。
在一些实施例中，第一支撑面322和第二支撑面323均设置于第三凸耳326上，且平行于转轴33的中轴线，从而使得在铰链臂32绕转轴33相对于铰链座31转动时，使得第一支撑面322和第二支撑面323均可能进入第一凸耳314和第二凸耳316之间的间隔区域。
进一步地，支撑件34位于座本体313的第一凸耳314和第二凸耳316之间，且支撑件34的第三支撑面341朝向第三凸耳326设置。在一个应用场景中，弹性件35完全设置于容置腔3121内，并在朝向第一凸耳314和第二凸耳316之间的间隔区域的一侧与支撑件34接触。在弹性件35处于自然状态时，支撑件34靠近弹性件35的区域至少部分位于容置腔3121内。需要指出的是，支撑件34位于于容置腔3121内的部分的形状与容置腔3121匹配，从而使得在弹性件35将支撑件34进行弹性偏置时，支撑件34位于容置腔3121的部分能够在容置腔3121内稳定滑动。
在一个应用场景中，在垂直于铰链座31的长度方向的截面上，容置腔3121的截面面积小 于第一凸耳314和第二凸耳316之间的间隔区域的截面面积，支撑件34位于容置腔3121外的区域的形状与间隔区域匹配，从而使得支撑件34在朝向弹性件35一侧移动时，不至于全部进入容置腔3121内。
当然，在其它实施例中，在垂直于铰链座31的长度方向的截面上，容置腔3121的截面形状也可以与第一凸耳314和第二凸耳316之间的间隔区域相同，此时，支撑件34可完全容置于容置腔3121内，从而使得在支撑件34收到推动作用时，在整个容置腔3121内滑动。
进一步地，在上述实施例中的铰链30应用于本申请实施例中的铰链组件122时，铰链座31的第一端面312为第一凸耳314和第二凸耳316的朝向铰链臂32的端面，由臂本体325朝向凸出设置的第三凸耳326位于第一凸耳314和第二凸耳316之间的间隔区域内，从而使得第一凸耳314和第二凸耳316的第一端面312朝向臂本体325设置。在转轴33的中轴线方向的截面上，臂本体325进一步凸出于第三凸耳326从而形成朝向铰链座31的第一凸耳314和第二凸耳316的第二端面321。
本实施例中，在铰链臂32与铰链座31进行相对转动的过程中，第一凸耳314和第二凸耳316的第一端面312与臂本体325的第二端面321之间的间隙始终大于或小于连接线36的直径，从而使得连接线36不至于在铰链座31与铰链臂32的相对转动过程中夹入第一凸耳314和第二凸耳316与臂本体325之间，进而减少铰链30对连接线36的损伤。
在一个应用场景中，在第一凸耳314和第二凸耳316的第二端面321与臂本体325的第一端面312之间的间隙在铰链臂32与铰链座31进行相对转动过程中始终保持为远大于或远小于连接线36的直径，从而进一步减少铰链30对连接线36的损伤。
需要指出的是，本实施例中，第一端面312与第二端面321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连接线36直径的条件；或者在另一些实施例中，可以仅是两端面靠近连接线36的位置处的间隙满足大于或者小于连接线36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，在垂直于转轴33的中轴线的截面上，第一凸耳314和第二凸耳316朝向铰链臂32的端面和臂本体325朝向铰链座31的端面中的至少一者可采用倒角设置，以使得在铰链臂32与铰链座31进行相对转动过程中二者之间的间隙靠近连接线36的位置始终保持为大于连接线36的直径。
在一些实施例中，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，仅需要将靠近连接线36位置处的第一凸耳314和第二凸耳316朝向铰链臂32的端面和臂本体325朝向铰链座31的端面中的至少一者进行倒角设置而使得在铰链臂32与铰链座31进行相对转动过程中不会将连接线36夹入两端面之间的间隙中。
本申请中上述铰链实施例中的铰链可应用于本申请实施例中，但是并不做限定，在其它实施例中还可以应用于其它的铰链组件当中，或者两个需转动连接的构件直接连接均可。
需要注意的是，以上对扬声器装置的铰链组件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，在了解扬声器装置的铰链组件的基本原理后，可能在不背离这一原理的情况下，对实施扬声器装置的铰链组件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，扬声器装置的铰链组件还可以有第三固定位置，即用户不适用扬声器装置时，可以将铰链组件调整为第三固定位置，便于保管或者存放扬声器装置。诸如此类的变形，均在本申请的保护范围之内。
在一些实施例中，如图1所示，与眼镜架相连的功能件20可以为一种扬声器组件83。在一些实施例中，扬声器组件83可以包括但不限于耳机、MP3播放器、助听器等。
在一个应用场景中，本实施方式中的骨传导扬声器组件为上述眼镜实施方式中的扬声器组件83的一种仅仅为了说明的目的，以下将基于骨传导扬声器组件进一步描述扬声器组件83在人体上的贴合位置。需要知道的是，在不违背原理的情况下，以下描述的内容也可以同样适用于气导扬声器组件。
在一些实施例中，扬声器组件83在MP3播放器的位置可以是不固定的，扬声器组件83可以贴合用户脸颊的不同部位(例如耳前、耳后等)，使用户感受到不同的音质，用户可根据自己的喜好自行调节，还可方便不同头型大小的用户使用。扬声器装置通过耳挂20固定在人耳上，扬声器组件83位于耳前。在一些实施例中，耳挂20可以是弹性可发生形变的，将耳挂20进行折弯以改变扬声器组件83在人体的贴合位置。在一些实施例中，耳挂20用于与扬声器组件83的连接端可以根据用户习惯的位置进行设置，例如，用户习惯将扬声器组件83佩戴于耳后，可在保持耳挂20固定功能的前提下将耳挂20的连接端设置于耳后。关于耳挂20和扬声器组件83之间卡接的连接方式可以参考本申请其他地方的具体内容。需要注意的是，耳挂20与扬声器组件83之间的连接方式不限于上述的卡接，例如，耳挂20与扬声器组件83之间还可以通过铰接的方式进行连接，关于铰接的具体内容可以参考本申请其他地方的具体内容。
在一些实施例中，扬声器组件83可以贴合在使用者头部的任意位置，例如，头顶、额头、脸颊、鬓角、耳廓、耳廓背面等。在一些实施例中，扬声器组件83可以和头部的贴合方式可以为面贴合或者点贴合。贴合表面设有梯度结构，梯度结构指的是接触面表面存在高度变化的区域。梯度结构可以是接触面外侧(与使用者贴合的一侧)存在的凸起/凹下或者台阶状等结构，也可以是接触面内侧(背向使用者的一侧)存在的凸起/凹下或者台阶状等结构。
需要注意的是，以上对扬声器组件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，在了解扬声器组件的基本原理后，可能在不背离这一原理的情况下，对实施扬声器组件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，耳挂20耳挂20的形状可以根据扬声器组件83与人体头部的贴合位置进行调整。诸如此类的变形，均在本申请的保护范围之内。
正常情况下，扬声器装置的音质受到扬声器装置本身各组成部分的物理性质、各组成部分间振动传递关系、扬声器装置与外界的振动传递关系以及振动传递系统在传递振动时的效率等多方面的影响因素。扬声器装置本身的各组件部分包括产生振动的组件(例如但不限于耳机芯)，固定 扬声器装置的组件(例如但不限于耳挂20)，传递振动的组件(例如但不限于机芯壳体82上的面板、振动传递层等)。各组成部分间振动传递关系以及扬声器装置与外界的振动传递关系由扬声器与使用者间的接触方式(例如但不限于夹紧力、接触面积、接触形状等)决定。
仅仅为了说明的目的，以下将基于扬声器装置进一步描述音质和扬声器装置各组成部分的关系。需要知道的是，在不违背原理的情况下，以下描述的内容也可以同样适用于骨传导和气导扬声器装置。图19是本申请一些实施例提供的扬声器装置振动产生和传递系统的等效模型，如图19所示，包括固定端1101，传感终端1102，振动单元1103，以及耳机芯1104。在一些实施例中，固定端1101可以通过传递关系K1(图19中k 4)与振动单元1103相连，传感终端1102可以通过传递关系K2(图19中R 3，k 3)与振动单元1103相连，振动单元1103可以通过传递关系K3(图19中R 4，k 5)与耳机芯1104相连。
这里所说的振动单元是机芯壳体82，传递关系K1，K2和K3是扬声器装置等效系统中相应部分之间作用关系的描述(将在下文中详细描述)。等效系统的振动方程可以表示为：
m 3x″ 3+R 3x′ 3-R 4x′ 4+(k 3+k 4)x 3+k 5(x 3-x 4)＝f 3  (1)
m 4x″ 4+R 4x″ 4-k 5(x 3-x 4)＝f 4(2)
其中，m 3是振动单元1103的等效质量，m 4是耳机芯1104的等效质量，x 3是振动单元1103的等效位移，x 4是耳机芯1104的等效位移，k 3是传感终端1102和振动单元1103之间的等效弹性系数，k 4是固定端1101和振动单元1103之间的等效弹性系数，k 5是耳机芯1104和振动单元1103之间的等效弹性系数，R 3是传感终端1102和振动单元1103之间的等效阻尼，R 4是耳机芯1104和振动单元1103之间的等效阻尼，f 3和f 4分别是振动单元1103和耳机芯1104之间的相互作用力。系统中振动单元的等效振幅A 3为：
Figure PCTCN2019102403-appb-000001
其中，f 0表示单位驱动力，ω表示振动频率。由此可见，影响扬声器装置频率响应的因素包括振动的产生部分(例如但不限于振动单元1103、耳机芯1104、外壳以及相互连接方式，如公式(3)中m 3，m 4，k 5，R 4等)，振动传递部分(例如但不限于，与皮肤接触方式，耳挂的属性，如公式(3)中k 3，k 4，R 3等)。改变扬声器装置各部分的结构和各组件之间连接的参数，例如，改变夹紧力的大小相当于改变k 4的大小、改变胶水的粘结方式相当于改变R 4和k 5的大小、改变相关材料的硬度、弹性、阻尼等相当于改变k 3和R 3的大小，这些都可以改变扬声器装置的频率响应和音质。
在一个具体的实施例中，固定端1101可以是扬声器装置在振动过程中位置相对固定的点或者位置相对固定的区域(例如，耳挂顶端)，这些点或区域可以看做是扬声器装置在振动过程中的固定端，固定端可以是由特定的部件组成，也可以是根据扬声器装置整体结构确定的位置。例如，可以通过特定的装置将扬声器装置悬挂、粘接或吸附在人耳附近，也可以设计扬声器装置的结构和外形使得扬声器组件83部位能够贴住人体皮肤。
传感终端1102是人体接收声音信号的听力系统，振动单元1103是扬声器装置上用于保护、支撑、连接耳机芯1104的部分，包含将振动传递给使用者的振动传递层或者面板(机芯壳体82上 靠近人体的一侧)等与使用者直接或间接接触的部分，以及保护、支撑其他振动产生元件的外壳等。
传递关系K1连接固定端1101和振动单元1103，表示扬声器装置在工作过程中振动产生部分和固定端1101的振动传递关系，K1取决于扬声器装置的形状和构造。例如，扬声器装置可以以U型耳机架/耳机挂带形式固定在人体头部，也可以装置在头盔、消防面罩或者其他特殊用途的面具、扬声器装置等设备上使用，不同的扬声器装置的形状和构造都会对振动传递关系K1产生影响，进一步地，扬声器装置的构造还包括扬声器装置不同部分的组成材质、质量等物理性能。传递关系K2连接传感终端402和振动单元1103。
进一步的，K2取决于传递系统的组成，传递系统包括但不限于将声音振动通过使用者组织传递给听力系统。例如，声音通过皮肤、皮下组织、骨骼等传递给听力系统时，不同人体组织的物理性质以及相互连接关系都会对K2产生影响。进一步地，振动单元1103和人体组织接触，在不同实施例中，振动单元上的接触面可以是振动传递层或者是面板的一个侧面，接触面的表面形状、大小、与人体组织间的相互作用力等都会影响传递系数K2。
在一些实施例中，振动单元1103和耳机芯1104的传递关系K3是由扬声器装置振动产生装置内部的连接属性决定，耳机芯1104和振动单元1103通过刚性或弹性方式相连，或者改变连接件在耳机芯1104和振动单元1103间的相对位置，都会改变耳机芯1104将振动传递给振动单元1103，尤其是面板的传递效率，从而影响传递关系K3。
进一步的，在扬声器装置的使用过程中，声音的产生和传递过程都会影响到最终人体感受到的音质。例如以上提到的固定端1101、人体感觉终端1102、振动单元1103、耳机芯1104以及传递关系K1、K2和K3等，都可能对扬声器装置的音效质量产生影响。需要注意的是，此处K1、K2、K3只是对振动传递过程中涉及到不同装置部分或系统连接方式的一种表示，可以包含但不限于物理连接方式、力的传导方式、声音的传递效率等。
图20是本申请一些实施例提供的扬声器装置的复合振动装置的截面示意图；图21是本申请一些实施例提供的扬声器装置及其复合振动装置的爆炸示意图。
在一些实施例中，扬声器装置还设置有复合振动装置。在一些实施例中，复合振动装置可以是耳机芯中的一部分。扬声器装置上扬声器的复合振动装置的实施例如图20和图21所示，传振片1801和振动板1802组成一个复合振动装置，传振片1801设置为一第一圆环体1813，并在该第一圆环体内设置有向中心辐辏的三个第一支杆1814，其辐辏中心位置与振动板1802的中心固定。振动板1802的中心为配合辐辏中心及第一支杆的凹槽1820。振动板1802设置具有与传振片1801半径不同的第二圆环体1821，以及与第一支杆1814不同粗厚的三个第二支杆1822，在装配时第一支杆1814和第二支杆1822错开设置，可以但不限于呈60度角。
上述第一支杆和第二支杆都可以采用直杆或者设置成其它符合特定要求的形状，支杆数目可以设置为两个以上，采用对称或非对称排布，以满足经济、实用效果等方面的要求。传振片1801具有薄的厚度并且可增加弹力，传振片1801是卡在振动板1802的凹槽1820中心的。在振动板1802的第二圆环体1821下侧粘结设置有音圈1808。复合振动装置还包括底板1812，在该底板1812上 设置有环形磁体1810，在该环形磁体1810内同心设置有内磁体1811。在内磁体1811的顶面设置有内导磁板1809，同时在环形磁体1810上设置有环形导磁板1807，在环形导磁板1807上方固定设置有垫圈1806，传振片1801的第一圆环体1813与该垫圈1806相固定连接。该整个复合振动装置通过一面板1830与外部连接，面板1830固连传振片1801的辐辏中心位置，并卡合固定在传振片1801和振动板1802的中心位置。利用上述振动板和传振片组成的复合振动装置，可以得到如图22提供的频率响应，产生了两个谐振峰。通过调节两个部件的尺寸和材料等参数，可以使得让谐振峰出现在不同的位置，例如，使得低频的谐振峰出现在更低频移动的位置，和/或使得高频的谐振峰出现在更高频的位置。优选地，振动板的劲度系数大于传振片的劲度系数，振动板产生两个谐振峰中的高频谐振峰，传振片产生两个谐振峰中的低频谐振峰。这些谐振峰的范围可以设置在人耳可听到的声音的频率范围之内，也可以不在其中，优选地，两个谐振峰都不在人耳可听到的声音的频率范围内；更优选地，一个谐振峰在人耳可听到的声音的频率范围之内，另一个谐振峰在人耳可听到的声音的频率范围之外；更优选的，两个谐振峰都在人耳可听到的声音的频率范围内。这样就拓宽了扬声器的谐振响应范围，得到满足条件的音质。值得注意的是，在实际的使用过程中，可以设置多个传振片和振动板，形成多层振动结构，分别对应不同的频响范围，实现全音域全频响高品质的扬声器振动，或者使频率响应曲线在某些特定频率范围内达到使用要求。例如，在骨传导助听器中，为了满足正常听力要求，可以选择谐振频率在100Hz-10000Hz的范围内的一个或多个振动板、传振片构成的耳机芯。关于振动板和传振片构成的复合振动装置的描述出现于2011年12月23日提交的中国专利申请号201110438083.9中披露的，名称为“一种骨传导扬声器及其复合振动装置”的专利申请中，该专利文献全文引用在此作为参考。
图23是本申请一些实施例提供的扬声器装置及其复合振动装置的截面示意图；图24是本申请一些实施例提供的扬声器装置振动产生部分的等效模型图。
在另一个实施例中，如图23所示，扬声器装置的复合振动装置包括一个振动板2002，第一传振片2003和第二传振片2001。第一传振片2003将振动板2002和第二传振片2001固定在外壳2019(即，机芯壳体82)上，由振动板2002、第一传振片2003和第二传振片2001组成的复合振动装置可以产生不少于两个谐振峰，在听力系统可听范围内产生更加平坦的频率响应曲线，从而改善扬声器装置的音质。
在第一传振片的三重复合振动系统产生的谐振峰数多于没有第一传振片的复合振动系统产生的谐振峰。优选地，三重复合振动系统可以产生至少有三个谐振峰；更优选地，至少有一个谐振峰不在人耳可听到的范围之内；更优选地，谐振峰都在人耳可听到的范围之内；更进一步优选地，谐振峰都在人耳可听到的范围之内，且其峰值频率不高于18000Hz；更进一步优选地，谐振峰都在人耳可听到的声音的频率范围内，且其峰值在100Hz-15000Hz之间；更进一步优选地，谐振峰都在人耳可到的声音的频率范围内，且其峰值在200Hz-12000Hz之间；更进一步优选地，谐振峰都在人耳可到的声音的频率范围内，且其峰值在500Hz-11000Hz之间。在一个实施例中，通过利用振动板、第一传振片和第二传振片组成的三重复合振动系统，可以得到如图25提供的频率响应，产生了三个 明显的谐振峰，能够使扬声器装置频响在低频范围(600Hz左右)的灵敏度得到较大提升，提高了音质。
通过改变第一传振片的尺寸和材料等参数，可以让谐振峰发生移动，最终获得更理想的频率响应。优选地，第一传振片为一弹性片。该弹性由第一传振片的材料、厚度、结构等多方面决定。第一传振片的材料，例如但不限于，钢材(例如但不限于不锈钢、碳素钢等)、轻质合金(例如但不限于铝合金、铍铜、镁合金、钛合金等)、塑胶(例如但不限于高分子聚乙烯、吹塑尼龙、工程塑料等)，也可以是能达到同样性能的其他单一或复合材料。对于复合材料，例如但不限于玻璃纤维、碳纤维、硼纤维、石墨纤维、石墨烯纤维、碳化硅纤维或芳纶纤维等增强材料，也可以是其它有机和/或无机材料的复合物，例如玻璃纤维增强不饱和聚酯、环氧树脂或酚醛树脂基体组成的各类玻璃钢。第一传振片的厚度不低于0.005mm，优选地，厚度为0.005mm-3mm，更优选地，厚度为0.01mm-2mm，再优选地，厚度为0.01mm-1mm，进一步优选地，厚度为0.02mm-0.5mm。第一传振片的结构可以设定成环状，优选地，包含至少一个圆环，优选地，包含至少两个圆环，可以是同心圆环，也可以是非同心圆环，圆环间通过至少两个支杆相连，支杆从外环向内环中心辐射，进一步优选地，包含至少一个椭圆圆环，进一步优选地，包含至少两个椭圆圆环，不同的椭圆圆环有不同的曲率半径，圆环之间通过支杆相连，更进一步优选地，第一传振片包含至少一个方形环。第一传振片结构也可以设定成片状，优选地，上面设置镂空图案，镂空图案的面积不小于没有镂空的面积。以上描述中材料、厚度、结构可以组合成不同的传振片。例如，环状传振片具有不同的厚度分布，优选地，支杆厚度等于圆环厚度，进一步优选地，支杆厚度大于圆环厚度，更进一步优选地，内环的厚度大于外环的厚度。
本申请中针对上述的内容还公开了关于振动板、第一传振片、第二传振片的具体的实施例，图26是本申请一些实施例提供的扬声器装置的振动产生部分的截面示意图。如图26所示，耳机芯包括由导磁板2210，磁铁2211和导磁体2212组成的磁路系统，振动板2214，线圈2215，第一传振片2216和第二传振片2217。面板2213突出外壳2219，和振动片2214通过胶水粘结，第一传振片2216将耳机芯连接固定在外壳2219上，形成悬挂结构。
上述实施例中的壳体、机芯壳体和外壳也可以是同一结构。都可以用于指代容纳扬声器装置的外部壳体的结构。在一些实施例中，上述实施例中的面板可以是同一结构，都可以用于指代扬声器装置的外部壳体的与人体接触的部分。
在扬声器装置工作的过程中，由振动板2214，第一传振片2216和第二传振片2217组成的三重振动系统能够产生更为平坦的频率响应曲线，从而改善扬声器装置的音质。第一传振片2216将耳机芯弹性连接在外壳2219上，可以减少耳机芯传递给外壳的振动，从而有效地降低由于壳体振动导致的漏音，也减少了壳体的振动对扬声器装置音质的影响。图27是本申请一些实施例提供的扬声器装置振动产生部分的振动响应曲线。其中，粗线显示的是使用第一传振片2216后振动产生部分的频率响应，细线显示的是不使用第一传振片2216后振动产生部分的频率响应。可以看出，在500Hz以上的频率范围，不含有第一传振片2216的扬声器外壳的振动明显大于含有第一传振片2216的扬 声器的外壳的振动。图28所示是含有第一传振片2216和不含有第一传振片2216两种情况下的漏音比较。其中，含有第一传振片2216的装置在中频(例如1000Hz左右)范围的漏音小于不含有第一传振片2216的装置在对应频率范围的漏音。由此可以看出，面板和外壳间使用第一传振片后可以有效地降低外壳的振动，从而降低漏音。在一些实施例中，第一传振片可以采用包括但不限于不锈钢、铍铜、塑胶、聚碳酸酯材料，其厚度在0.01mm-1mm的范围内。
图29A和29B是本申请的一些实施例提供的扬声器装置的振动产生部分结构示意图和截面示意图。在一些实施例中，扬声器装置可以包括外壳26(即前述实施例中的机芯壳体82)、面板24和耳机芯25。在一些实施例中，外壳26与上述实施例中的机芯壳体82可以为同样的机构，都可以用于指代扬声器模块的外部壳体，耳机芯25可以包括前述实施例中的复合振动装置，同样的，面板24也可以遵循此原则。在一些实施例中，耳机芯25可以容置在外壳26的内部并产生振动。耳机芯25的振动会引起外壳26的振动，并由此推动壳外空气振动而产生漏音。外壳26的至少一部分上开设有至少一个引声孔60，引声孔60用于将外壳26内部空气振动所形成的壳内声波引出至外壳26的外部，与外壳26振动推动壳外空气所形成的漏音声波发生干涉。在一些实施例中个，干涉可以降低漏音声波的振幅。
面板24与耳机芯25固定相连，在耳机芯25的带动下同步振动。面板24从外壳26的开口伸出外壳26，至少部分与人体皮肤贴合，振动通过人体组织与骨骼传递到听觉神经，从而使人听到声音。在耳机芯25与外壳26之间可以通过连接件23相连，连接件23将耳机芯25定位在外壳26中。
连接件23可以为一个或多个独立的部件，也可以与耳机芯25或外壳26一体设置。在一些实施例中，为了减小对振动的约束，连接件23可以选择弹性材料制成。
在一些实施例中，引声孔60可以设置在侧壁高度的上部，例如，从顶部(面板24)到侧壁高度方向1/3高度的部分。
以圆柱形外壳为例，对于设置位置，根据不同的需求，引声孔60可以开设于外壳侧壁261和/或外壳底壁262。优选引声孔60开设在外壳侧壁261的上部和/或下部。开设在外壳侧壁261的引声孔数量可以为至少两个，优选是呈环状周向均匀分布。开设在外壳底壁262的引声孔数量可以为至少两个，以底壁的中心为圆心，呈环状均匀分布。呈环状分布的引声孔可以设置至少一圈。开设在外壳底壁262的引声孔数量可以为仅有一个，该引声孔设置在底壁262的中心处。
对于数量，引声孔可以为一个或多个，优选是有多个，均匀布设。对于环状布设的引声孔，每圈引声孔的数量例如可以为6-8个。
引声孔的形状可以为圆形、椭圆形、矩形或长条形等。长条形一般是指沿直线、曲线或弧线的条状。各种形状的引声孔60在一个扬声器上可以相同或不同。
在一些实施例中，在外壳26的侧壁下部(侧壁高度方向2/3高度到底部的部分)开设有贯通的引声孔60。引声孔60的数量可以是，例如，8个，形状可以是，例如，矩形。各引声孔60呈环形均匀分布在外壳26的侧壁上。
在一些实施例中，外壳26为圆柱状，在外壳26的侧壁中部(侧壁高度方向1/3高度到2/3高度的部分)开设有贯通的引声孔60。引声孔60的数量为8个，形状为矩形，各引声孔60呈环形均匀分布在外壳26的侧壁上。
在一些实施例中，在外壳26的底壁的周向开设有贯通的引声孔60。引声孔60的数量例如为8个，形状例如为矩形，各引声孔60呈环形均匀分布在外壳26的底壁上。
在一些实施例中，在外壳26侧壁的上部和下部分别开设有贯通的引声孔60。引声孔60呈环状均匀分布在外壳26侧壁的上部和下部，每圈引声孔60的数量为8个。且上部和下部设置的引声孔60相对于外壳26的中截面对称设置。每个引声孔60的形状为圆形。
在一些实施例中，在外壳26侧壁的上部和下部，以及外壳26的底壁分别开设有贯通的引声孔60。侧壁开设的引声孔60呈环状均匀分布在外壳26侧壁的上部和下部，每圈数量为8个，且上部和下部设置的引声孔60相对于外壳26的中截面对称设置。侧壁开设的每个引声孔60为矩形。底壁开设的引声孔60的形状为沿弧线设置的长条形，数量为4个，以底壁的中心为圆心呈环形均匀分布。且底壁开设的引声孔60还包括开设在中心处的圆形的通孔。
在一些实施例中，在外壳26侧壁的上部开设有贯通的引声孔60，呈环状均匀分布在外壳26侧壁的上部，数量例如为8个，引声孔60的形状为圆形。
在一些实施例中，为了显示出抑制漏音的较优效果，分别在外壳侧壁261的上部、中部和下部均周向均布有引声孔60，在外壳底壁262也周向开设有一圈引声孔60。各引声孔60的孔径大小和孔的个数均相同。
在一些实施例中，引声孔60可以为无遮挡的贯通孔，以在引声孔60的开口处设置阻尼层。阻尼层的材料选择和设置位置可以有多种方式，例如，阻尼层为调音纸、调音棉、无纺布、丝绸、棉布、海绵或橡胶等对音质传导具有一定阻尼的材料，可以在引声孔60内壁贴附阻尼层，或者在引声孔60的孔口外侧罩设阻尼层等。
在一些实施例中，对应不同引声孔之间，可以将所设置的阻尼层设置为不同引声孔60之间具有相同的相位差以抑制相同波长的漏音，或设置为不同的引声孔60之间具有不同的相位差以抑制不同波长的漏音(即特定波段的漏音)。
在一些实施例中，同一引声孔60的不同部位之间设置为具有相同的相位(例如，使用预先设计好的阶梯或台阶状的阻尼层)，以抑制相同波长的漏音声波；或者，同一引声孔60的不同部位之间，设置为具有不同的相位，以抑制不同波长的漏音声波。
耳机芯25不仅带动面板24振动，耳机芯25自身也是一个振动源，其容置在外壳26的内部，耳机芯25表面振动使外壳内空气随之振动，形成的声波是在外壳26内部的，可称为壳内声波。面板24和耳机芯25通过连接件23定位在外壳26上，不可避免地会将振动作用于外壳26上，带动外壳26同步振动，所以外壳26推动壳外空气振动即形成了漏音声波。漏音声波向外传播，就形成了漏音。

上包含了完整的相位和幅度信息，其相位、幅度与扬声器装置的外壳26尺寸、耳机芯的振动频率、引声孔的开设位置、形状、数量、尺寸及孔上是否有阻尼都有密切关系，这就使我们可以通过调整引声孔的开设位置、形状和数量和/或增加阻尼和/或调整阻尼材料来达到抑制漏音的目的。
壳内声波和漏音声波相当于中提供的两个声源。本发明实施例在外壳的壁面上开设了贯通的引声孔60，能够将壳内声波引导传播至壳外，与漏音声波同在空气中进行传播，发生干涉，从而降低漏音声波的振幅，即减小了漏音。因此，本申请的技术方案，通过在外壳上开设引声孔这一便捷改进，即在一定程度上解决漏音问题，且不增加扬声器装置的体积和重量。
根据发明人所推导的上述公式，本领域技术人员容易理解的是，漏音声波的消除效果，与扬声器装置的外壳尺寸、耳机芯的振动频率、引声孔的开设位置、形状、数量、尺寸及孔上是否有 阻尼都有密切关系，所以，引声孔60的开设位置、形状、数量、孔上的阻尼材料等可以根据需要有多种不同的变化方案。
图30是本申请的一些实施例提供的扬声器装置的抑制漏音的效果图。在扬声器装置(例如，如图29A和29B提供的扬声器装置)附件的目标区域中，漏音声波传递至目标区域的相位，与壳内声波经引声孔传播至该目标区域的相位之间，相差接近180度。通过此设置，可使得外壳产生的漏音声波在目标区域显著降低、甚至消除。
如图30所示，在1500Hz～4000Hz频段内，漏音声波被显著抑制。其中，在1500Hz～3000Hz频段内，被抑制的漏音基本超过10dB。特别是在2000Hz～2500Hz这个频段内，在外壳侧面上部开设引声孔后，漏音比未开设引声孔的方案降低了超过20dB。
需要注意的是，以上对扬声器装置的描述仅仅是具体的示例，不应该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，在了解扬声器装置的基本原理后，可能在不背离这一原理的情况下，对实施扬声器装置的具体方式和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，引声孔60的孔径大小可以不一致，以抑制不同波段的漏音。诸如此类的变形，均在本申请的保护范围之内。
图31是本申请一些实施例提供的双定位式扬声器装置的分解立体示意图；图32是本申请一些实施例提供的双定位式扬声器装置的剖视示意图，图33是图32中A向局部放大示意图。图34是本申请一些实施例提供的双定位式扬声器装置的组合示意图(去除支撑部)；图35是图34中磁性组件、定位组件以及音圈的组装示意图；图36是图34中磁性组件和定位组件的组装示意图；图37是图34中磁性组件的结构示意图；图38是图37的剖视示意图。请参阅图31-图38，在一些实施例中，双定位式扬声器装置可以包括耳机芯和支撑部(即前述实施例中的机芯壳体)。其中，耳机芯可以包括磁性组件、设于磁性组件与支撑部之间的(弹性)定位组件、音圈和垫圈。

结合图31和图32，在一些实施例中，支撑部(即前述实施例中的机芯壳体)可以包括第一壳体1和第二壳体9，第一壳体1与第二壳体9相接可形成用于容纳磁性组件、弹性元件和/或音圈的容纳空间。第一壳体1可以与第一导磁体5处于同一侧，两者之间可以具有间隙。第二壳体9 可以与第二导磁体7处于同一侧，两者之间可以具有间隙。这里所说的支撑部可以为支架，也可以为其它可对磁性组件和定位组件起到支撑作用的装置。
在一些实施例中，第一壳体1与第二壳体9所形成的容纳空间里可以固定设置一垫圈3，该垫圈3优选为环形。环形垫圈3的内径小于第一壳体1和第二壳体9的内径，使得该环形垫圈3的内侧边相对于第一壳体1和第二壳体9朝向内侧凸出，环形垫圈3的外径与第一壳体1和第二壳体9的外径可以相同，也可以不同。优选地，环形垫圈3的外径与第一壳体1和第二壳体9的外径相同，以形成光滑、平整的外平面。垫圈3可以固定设置于第一壳体1与第二壳体9相接处，也可固定安装于第一壳体1与第二壳体9形成的容纳空间的内侧。垫圈3、第一壳体1和第二壳体9之间可以采用一定的方式连接为一体。上述连接方式可以是物理方式，例如卡接和焊接，也可以是化学方式，例如粘结，优选地，垫圈3、第一壳体1和第二壳体9之间可采用粘接方式连接为一体。
在一些实施例中，在第二壳体9内侧，即朝向第一壳体1的一侧，底面上设置台阶面91，第二弹性元件8的下表面固定设置于台阶面91上。第二弹性元件8和台阶面91可以一定的方式连接在一起，上述连接方式可以是物理方式，例如卡合和焊接，也可以是化学方式，例如粘结，优选地，第二弹性元件8与台阶面91之间可以通过粘结方式连接。
在一些实施例中，垫圈3上可以固定设置一音圈4，音圈4可固定于垫圈3的内侧下表面上。该垫圈3与音圈4之间可以采用一定的方式连接为一体。该连接方式可以是物理方式，例如卡接和焊接，也可以是化学方式，例如粘结，优选地，垫圈3与音圈4之间采用粘接方式连接为一体。音圈4从垫圈3的内侧下表面继续向下延伸，并处于第一导磁体5与第二导磁体的环形侧边73所形成的磁间隙内。
结合图31、图33、图34、图35、图36以及图37，在一些实施例中，第一导磁体5的中心，可以设置有凸出的第一台阶51，第一台阶51延伸的方向为远离磁铁6和第二导磁体7，通过第一台阶51在第一导磁体5与第一弹性元件2之间形成振动空间，保证第一弹性元件2能带动第一导磁体5振动，如果没有设置此第一台阶51，第一弹性元件2虽然能带动磁性组件振动，但是会产生杂音。弹性元件的中心区域沿对称轴线方向变形最大，边上和壳体粘接的区域变形最小。由于弹性元件带动磁性组件振动，而磁性组件沿轴线方向的位移是弹性元件中心的变形量，第一台阶51的高度可以保证磁性组件和弹性元件之间形成振动空间大小，优选地，第一台阶51的高度大于弹性元件在中心区域沿对称轴线方向形变的最大值，以避免磁性组件在运动过程中打到弹性元件，形成杂音。在第一台阶51的中心，可以设置有凸出的第一定位部52，第一定位部52延伸的方向为远离磁铁6和第二导磁体7，通过第一定位部52对第一导磁体5进行定位。

在一些实施例中，第二导磁体7的中心可以设置具有一个台阶部，其内底可以设置为更低 更薄，由此相对于台阶部可以形成凹部，第二导磁体7的中心也可以不设置该台阶部及凹部。这里所说的凹部可以用来放置磁铁，可以采用一定的方式将磁铁固定连接在第二导磁体7的凹部内，可以是物理方式，例如卡接和焊接，也可以是化学方式，例如粘结，优选地，磁体采用粘接方式固定连接在第二导磁体7的凹部内。这里所说的凹部的设置方便了装配但会导致磁场的减弱，优选地，可以根据需要设计调整不同深度的台阶部及凹部，也可以不设置该台阶部及凹部。
在一些实施例中，第二导磁体7的中心，可以设置有凸出的第二台阶74，第二台阶74延伸的方向为远离磁铁6和第一导磁体5，通过第二台阶74在第二导磁体7与第二弹性元件8之间形成振动空间，保证第二弹性元件8能带动第二导磁体7振动，如果没有设置此第二台阶74，第二弹性元件8虽然能带动磁性组件振动，但是会产生杂音。弹性元件的中心区域沿对称轴线方向变形最大，边上和壳体粘接的区域变形最小。由于弹性元件带动磁性组件振动，而磁性组件沿轴线方向的位移是弹性元件中心的变形量，第二台阶74的高度可以保证磁性组件和弹性元件之间形成振动空间大小，优选地，第二台阶74的高度大于弹性元件在中心区域沿对称轴线方向形变的最大值，以避免磁性组件在运动过程中打到弹性元件，形成杂音。在第二台阶74中心，可以设置有凸出的第二定位部75，第二定位部75延伸的方向为远离磁铁6和第一导磁体5，通过第二定位部75对第二导磁体7进行定位。
在一些实施例中，定位组件可以包括第一弹性元件2和第二弹性元件8，第一弹性元件2和第二弹性元件8可以分别位于磁性组件的两侧。第一弹性元件2可被固定在第一定位部52和垫圈3上，第二弹性元件8可被固定在第二壳体9和第二定位部75上。第一弹性元件2和垫圈3可以组成复合振动装置，通过双重的复合振动可产生两个谐振峰。进一步地，调节两个部件的尺寸和材料参数，可以让谐振峰发生移动，低频的谐振峰向越低频移动，高频的谐振峰向越高频移动，使得这些谐振峰范围都在耳朵所能听到的范围内，拓宽了音响的谐振相应范围，得到理想的声音。第一弹性元件2和/或第二弹性元件8可以采用包括但不限于不锈钢、铍铜、塑胶、PC等弹性材质，优选地，第一弹性元件2和/或第二弹性元件8的厚度为0.04mm～0.20mm，更优选地，第一弹性元件2和/或第二弹性元件8的厚度为0.08mm～0.12mm。优选地，第一弹性元件2为一弹性板，可以设置为具有第一内圆环体和第一外圆环体，第一内圆环体位于第一外圆环体的中心，在该第一外圆环体中可以向中心辐辏地设置了不少于一个的第一支杆822，在第一内圆环体中心可以设置有第一定位孔；优选地，第二弹性元件8为一弹性板，可以设置为具有第二内圆环体和第二外圆环体，第二内圆环体位于第二外圆环体的中心，在该第二外圆环体中可以向中心辐辏地设置了不少于一个的第二支杆882，在第二内圆环体中心可以设置有第二定位孔。第一支杆和第二支杆的数目可以相同，也可以不同，优选地，第一支杆和第二支杆的数目为大于等于二。优选地，支杆为直杆；优选地，支杆的宽度为0.4mm～1.5mm，更优选地，支杆的宽度为0.6mm～1.0mm。
优选地，第一弹性元件2的外径，即第一外圆环体的外径，小于第一壳体1的内径；优选地，在磁性组件的轴向上，第一弹性元件2与第一壳体1也具有间隙，第一弹性元件2与第一壳体1没有直接的接触。第一弹性元件2与垫圈3之间以一定的方式连接在一起，上述连接方式可以是 物理方式，例如卡合和焊接，也可以是化学方式，例如粘结，优选地，第一弹性元件2与垫圈3之间的连接方式为粘结。
在一些实施例中，第一弹性元件2中的第一定位孔27与第一导磁体5上的第一定位部52相配合，两者采用一定的方式固接在一起，可以是物理方式，例如卡合，螺栓和焊接，也可以是化学方式，例如粘结，优选地，采用卡合或粘接的方式固接，更优选地，固接方式为同心固接；第二弹性元件8中的第二定位孔81与第二导磁体7上的第二定位部75相配合，两者采用一定的方式固接在一起，可以是物理方式，例如卡合，螺栓和焊接，也可以是化学方式，例如粘结，优选地，采用卡合或粘接的方式固接，更优选地，固接方式为同心固接。在具体的安装过程中，第一导磁体5的中心凸设第一定位部52，对应的在第一弹性元件2的中心凹设第一定位孔27，安装时将第一定位部52插入第一定位孔27内，实现第一导磁体5与第一弹性元件2同心固接；第二导磁体7的中心凸设第二定位部75，对应的在第二弹性元件8的中心凹设第二定位孔81，安装时将第二定位部75插入第二定位孔81内，实现第二导磁体7与第二弹性元件8同心固接。
需要说明的是，本申请实施例的双定位式的扬声器装置可以是基于气传导或者骨传导技术。在一些实施例中，当扬声器装置为双定位式的骨传导扬声器装置时，由第一导磁体5、磁铁6和第二导磁体7组成的磁性系统在音圈4通电时产生电流感应，进而使磁性系统的磁场强度发生变化，电感等参数也随之发生变化，音圈4在磁场中受到安培力的作用，从而使得音圈4与第一导磁体5、磁铁6、第二导磁体7之间产生纵向的往返运动。振动由垫圈3传递给第一壳体1、第二壳体9，并由与人骨直接接触的部位将声音振动传递到人骨，从而让人感应声音。音圈4固定在垫圈3上，使得在扬声器工作时，音圈4的安装位置不会发生偏移，由于第一导磁体5和第二导磁体7与弹性元件之间的位置相对固定，也即磁间隙10的安装位置不变，进而保证了音圈的安装稳定性，从而从根本上保证了扬声器装置的音质。
以上对双定位式扬声器装置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，在了解双定位式扬声器装置的基本原理后，可能在不背离这一原理的情况下，对实施双定位式扬声器的具体方式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，第一支杆和第二支杆的数目均为三。诸如此类的变形，均在本申请的保护范围之内。
在一些实施例中，以上描述的扬声器装置可以通过气传导的方式将声音传递给用户。当采用气传导的方式传递声音时，扬声器装置可以包括一个或多个声源。声源可以位于用户头部的特定位置，例如，头顶、额头、脸颊、鬓角、耳廓、耳廓背面等，而不用堵塞或者覆盖耳道。出于描述的目的，图39是显示一种通过气传导的方式传递声音的示意图。
如图39所示，声源3010和声源3020可以产生相位相反的声波(图中以“+”和“-”表示相位相反)。为简单起见，这里所说的声源指的是扬声器装置上输出声音的出声孔。例如，声源3010和声源3020可以是分别位于扬声器装置上特定位置(例如，机芯壳体82，或者电路壳体101)的两个出声孔。
在一些实施例中，声源3010和声源3020可以由同一个振动装置3001产生。振动装置3001包括振膜(未显示在图中)。当振膜受到电信号驱动而振动时，振膜正面驱动空气振动，通过导声通道3012在出声孔处形成声源3010，振膜背面驱动空气振动，通过导声通道3022在出声孔处形成声源3020。所述导声通道指的是振膜到对应出声孔的声音传播路径。在一些实施例中，所述导声通道是由扬声器上特定结构(例如，机芯壳体82，或者电路壳体101)围成的路径。需要知道的是，在一些可替代的实施例中，声源3010和声源3020还可以由不同的振动装置，分别通过不同的振膜振动产生。
由声源3010和声源3020产生的声音中，一部分传递给用户耳朵形成用户听到的声音，另一部分传递到环境中形成漏音。考虑到声源3010和声源3020距离用户耳朵的位置较近，为了描述方便，传递到用户耳朵的声音可以称为近场声音，传递到环境中的漏音可以称为远场声音。在一些实施例中，扬声器装置产生的不同频率的近场/远场声音与声源3010和声源3020之间的间距有关。一般说来，扬声器装置产生的近场声音会随着两个声源之间间距的增大而增大，而产生的远场声音(漏音)会随着频率的增加而增大。
针对不同频率的声音，可以分别设计声源3010和声源3020之间的间距，使得扬声器装置产生的低频近场声音(例如，频率小于800Hz的声音)尽可能大，且高频远场声音(例如，频率大于2000Hz的声音)尽可能小。为了达到以上目的，所述扬声器装置中可以包括两组或两组以上的双声源，每组双声源包含类似于声源3010和声源3020的两个声源，并分别产生特定频率的声音。具体地，第一组双声源可以用于产生低频声音，第二组双声源可以用产生高频声音。为了获得较大的低频近场声音，第一组双声源中两个声源之间的距离可以设置为较大的值。并且由于低频信号的波长较长，双声源之间较大的距离不会在远场形成过大的相位差，因而也不会在远场中形成过多的漏音。为了使得高频远场声音较小，第二组双声源中两个声源之间的距离可以设置为较小的值。由于高频信号的波长较短，双声源之间较小的距离可以避免在远场形成大的相位差，因而可以避免形成大的漏音。第二组双声源之间的距离小于所述第一组双声源之间的距离。
本申请实施例可能带来的有益效果包括但不限于：(1)将电路壳体和壳体护套分别成型，可以避免高温对控制电路或电池的损伤。(2)第一壳体护套和第二壳体护套并不完全包覆整个电路壳体，能够露出用于用户操作的部件，方便用户使用。(3)由振动板、第一传振片和第二传振片组成的复合振动装置可以产生不少于两个谐振峰，在听力系统可听范围内产生更加平坦的频率响应曲线，从而改善扬声器装置的音质。(4)保证了音圈的安装稳定性，从而从根本上保证了扬声器装置的音质。需要说明的是，不同实施例可能产生的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种的组合，也可以是其他任何可能获得的有益效果。
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。
最后，应当理解的是，本申请中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。
