为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
本申请一些实施例提供一种头戴耳机。
请参阅图1、图2以及图9，在一实施例中，该头戴耳机包括头带100和分别连接于头带100两端的两个耳机头200，其中，耳机头200包括耳壳220、耳罩230以及万向调节件210；耳壳220连接于头带100的一端；耳罩230内置发声器；万向调节件210连接于耳壳220和耳罩230之间并可让耳罩230相对与耳壳220进行任意调 节。
基于此结构设计，由于耳壳220的连接环222和耳罩230的外端之间通过万向调节件210连接，故在头戴耳机的实际使用过程中，耳罩230就会根据与使用者耳部的实际贴合情况，通过万向调节件210的变形调节，而实现耳罩230可相对耳壳220的万向任意调节，从而可以有效提高耳罩230与人体耳部的贴合性，进而使得使用者在佩戴本头戴耳机时的舒适性大大增加。
请参阅图1和图9，在一个实施例中，耳壳220上端与头带100连接，下端设有呈环形设置的连接环222，耳罩230远离耳朵的外端位于连接环222的内环面所围成的空间中；万向调节件210连接于连接环222和耳罩230的外端之间，并可让耳罩230相对耳壳220进行万向调节。在此需特别说明的是，连接环222即为一个空框，万向调节件210即置于该空框内，换言之，在本实施例中，呈环状的万向调节件210的外环面直接与连接环222的内环面贴合连接，且万向调节件210的内环面也位于连接环222的内环面所围成的空间中。
在一个实施例中，万向调节件210由以下材料中的至少一种制成：弹性硅胶、弹性橡胶、弹性塑料、弹性织物、弹性膜材料，例如，万向调节件210的材质可优选为成本低廉且成型便利的橡胶圈或硅胶圈。如此，当耳罩230需要相对耳壳220进行角度调整时，就可以充分利用弹性材料的弹性拉伸或回复性能来完成，其角度调整十分方便。在此，为保持万向调节件210的弹力性能一致，万向调节件210优选采用同一种弹性软性材料制成，当然，于其他实施例中，也可以根据特殊的设计需求，万向调节件210也可以由多种弹性材料复合制成，且尺寸规格等根据需要设计。
请参阅图1、图9和图5，在一个实施例中，万向调节件210为由弹性膜材料制成的万向调节膜240，且万向调节膜240呈环状设置，万向调节膜240的外环面与连接环222的内环面连接，万向调节膜240的内环面与耳罩230的外端外边缘连接。在耳机佩戴过程中，当耳罩230需要调整与人体耳部的贴合程度时，以朝向另一耳机头200的方向为内侧，耳罩230向外移动的部分就会使得位置对应处的部分膜弹性压缩，而耳罩230向内移动的部分就会使得位置对应处的部分膜弹性拉伸，这样，无论耳罩230朝哪个方向调节，其相应位置的万向调节膜240都会发生 对应的弹性改变，从而可顺利实现其万向调节作用。
在一个实施例中，万向调节膜240与连接环222和耳罩230之间均通过二次成型密封连接，其装配和制作过程均十分便利；且如图5和图6所示万向调节膜240的外环面和内环面之间的区域呈凹凸立体环状设置，可以有效增加万向调节膜240的调节量，使得耳罩230相对耳壳220的万向任意调节更加灵活。
在一个实施例中，万向调节膜240的外环面与连接环222的内环面之间，以及万向调节膜240的内环面与耳罩230的外端外边缘之间均通过超声密封焊接。当然，于其他实施例中，万向调节膜240还可以但不限于通过粘胶粘接等方式连接，但在本实施例中，超声密封焊接的方式生产效率更高且连接效果更好。在此，密封连接的设置，一方面可使得万向调节膜240和耳壳220及耳罩230之间连接更紧密，而不易出现因万向调节膜240脱离而导致角度调整不顺利的情况发生；另一方面，密封连接还可以对耳罩230内部的重要元器件起到很好的保护作用，可防止水和灰尘等进入，且头戴耳机的外表也更简洁美观。
请参阅图5和图6，在一个实施例中，万向调节膜240的外环面上设有第一限位部，连接环222的内环面设有与第一限位部适配限位连接的第二限位部，万向调节膜240的内环面的外边缘向外延伸形成有连接凸缘242。可以理解，第一限位部和第二限位部的适配限位连接，可使得万向调节膜240与连接环222的位置相对固定，进而方便成型连接，还可以进一步提高两者之间的连接密封性。具体在本实施例中，第一限位部为设于万向调节膜240的外环面上的环状限位槽241，第二限位部为于连接环222的内环面上凸设的环状限位凸条225。然本设计不限于此，于其他实施例中，也可以在万向调节膜240的外环面上设置环状限位凸条225，而在连接环222的内环面上设置适配的环状限位槽241；或者，环状限位凸条225也可以由多个沿周向间隔分布的凸块替代，相应地，在万向调节膜240的外环面上设置适配的插槽等，在此不做限制。此外，连接凸缘242的设计可以增大万向调节膜240和外盖231外边缘之间的有效连接面积，从而有利于增强两者之间的连接牢固性和密封性。
在一实施例中，如图1所示，连接凸缘242的外端端面与耳罩230的外端端面平齐，如此，可使本头戴耳机的外形更加简洁美观，且不易积攒灰尘等在连接缝 隙中。此外，万向调节膜240的外环面和内环面之间的区域向内凹设形成有环状的内凹槽243。此内凹槽243的设计可以有效增加万向调节膜240的调节量，使得耳罩230相对耳壳220的万向任意调节更加灵活。当然，于其他实施例中，万向调节膜240的外环面和内环面之间的区域也可以向外凸出设计，但在本实施例中，内凹设计可防止万向调节膜240在外凸时易磨损损坏的现象发生。
在一个实施例中，连接环222与耳罩230共中心轴设置，且万向调节膜240沿各径向的宽度一致。这样，就可以实现万向调节膜240在各个方向上的调节量均一致，从而有利于方便耳罩230相对耳壳220的万向调节，从而提高耳机佩戴的舒适性。
请参阅图13，在另一个实施例中，万向调节件210还可以为连接于耳壳220和耳罩230之间的多个弹簧。弹簧的具体数量为四个，其中两个弹簧相对共轴设置，另外两个弹簧也相对共轴设置；且两相对的弹簧的轴线与另外两个相对的弹簧的轴线交叉垂直。这样，不但结构设计简单，便于装配，而且可以很好的同时兼顾上下左右前后方向的角度和位置调节，而两相对弹簧共轴的设置可使得弹簧在弹性变形时，尽可能减少无用的弹性力矩和变形，从而提高弹簧的寿命。当然，于其他实施例中，还可以根据实际设计需要，设置合适的弹簧数量，但优选设置数量为偶数，以获得更好的调节力度平衡。
在一实施例中，弹簧至少一端与耳壳220或耳罩230枢接，如此，也可实现耳罩230相对耳壳220的多轴向旋转，并配合弹簧的弹性变形，从而获得较好的角度和位置调节效果。
请参阅图2至图4，以及图9，在一个实施例中，耳罩230包括耳罩壳体232、外盖231以及内盖233，耳罩壳体232具有向外敞口设计的安装腔234，安装腔234中内置有发声组件，外盖231可拆卸盖合安装腔234的敞口，内盖233与耳罩壳体232可拆卸连接，如此，不但有利于万向调节膜240的安装固定便利，而且也有利于整个耳罩230的装配便利。在本实施例中，耳壳220具有安装腔234，发声组件内置于安装腔234中，发声组件包括电池310、PCB板320和喇叭，喇叭(未示出)分别与电池310和PCB板320电连接，如此，就可实现耳机的放声功能。此外，在安装腔234中，还设有双面胶350、喇叭后盖330、密封圈340等部件。其中， 双面胶350用于粘接固定电池310，喇叭后盖330和耳罩壳体232围合形成用以安装喇叭的容置空间，在喇叭后盖330与耳罩230的内盖233之间还设有密封圈340，以起到一定的密封作用。
一并参照图10至图12，在一个实施例中，外盖231与耳罩壳体232可拆卸螺接。当然，于其他实施例中，两者可以通过但不限于卡接等其他可拆卸方式连接。但在本实施例中，螺接方式可使外盖231和耳罩壳体232连接得更加牢固。具体在本实施例中，外盖231的内板面上间隔设有多个第一螺接柱231a，每一第一螺接柱231a上设有具有内螺纹的螺孔，耳罩壳体232的安装腔234的槽底凸设有与第一螺接柱231a适配连接的第二螺接柱232a，第二螺接柱232a设有沿轴向贯穿第二螺接柱232a的贯穿孔232c，连接件穿设贯穿孔232c后与第一螺接柱231a螺接。
请参阅图10至图12，在一实施例中，第二螺接柱232a朝向第一螺接柱231a的前端端面上内凹形成有限位孔232b，贯穿孔232c设于限位孔232b的孔底面，第一螺接柱231a的后端适配插置于限位孔232b中，且第一螺接柱231a的后端端面与限位孔232b的孔底面抵接。如此，就可保证第一螺接柱231a和第二螺接柱232a的装配到位，从而确保安装腔234的尺寸容积等与设计一致，而且，在装配过程中，此设计也能确保安装腔234中的各重要元器件不会受挤压而损坏。此外，如图11和图12所示，第一螺接柱231a的外周侧面间隔分布有多个限位加强筋231b，主要起到加强第一螺接柱231a与外盖231内侧面的连接，以及在第一螺接柱231a插置于限位孔232b中时加强限位等作用；同理，第二螺接柱232a的外周侧面也设有多个加强筋232d，以加强第二螺接柱232a与耳罩壳体232之间的连接强度。
请参阅图9至图10，在一实施例中，外盖231呈类矩形设计，其四个转角处呈圆倒角设计，四个第一螺接柱231a分别邻近外盖231的四个转角设置。这样，在装配时，外盖231的四角均能得到固定，且连接力度均匀分布。此外，在外盖231的内侧面上还间隔凸设有多个定位片，主要用于在装配好后抵接电池310，以防止电池310位置移动。安装腔234的底面向内凸出形成出音凸台235，出音凸台235上设有若干贯穿的出音孔235a，喇叭发出的声音可通过出音孔235a发出。在此，出音凸台235的设置有效增大了安装腔234的容积，方便了喇叭的安装，而且还可使喇叭更接近人体耳部，其音效效果更好。此外，耳罩230还包括内盖233 ，内盖233和耳罩壳体232可以但不限于通过螺接等方式可拆卸连接，内盖233上开设有较大的通孔以供出音凸台235凸出显露出来，内盖233的内侧面连接有软质的与人体耳部贴合的环套，环套内填充有海绵等软性材料，以使耳机佩戴更加舒适。
请参阅图9和图11，在一个实施例中，耳罩壳体232的外周侧面包括位于邻近连接环222一侧的环状让位区域232e，以及位于远离连接环222一侧的内侧区域232f，让位区域232e呈内凹的环状槽设置，内侧区域232f上开设有供连接线400穿设的第一通孔232h。由于该让位区域232e呈内凹设置，即耳罩壳体232与外盖231的连接处低于内侧区域232f的外周平面，故可为万向调节件210的运动提供充足的活动空间，使得耳罩230相对耳壳220的角度调节更加灵活。
在一个实施例中，如图11所示，让位区域232e的邻近头带100的顶部设有第二通孔232g，第二通孔232g与发声组件连通。第二通孔232g和喇叭后盖330上设置的上敞口的振动腔连通，以进一步提高喇叭的音效，使本头戴耳机获得更好的使用体验。
请参阅图2、图3、图7和图8，在一个实施例中，头戴耳机还包括拉伸臂结构和连接线400；拉伸臂结构包括拉伸臂221和位置调节机构，拉伸臂221的两端分别与头带100和连接环222连接，位置调节机构设于拉伸臂221和头带100之间，拉伸臂221可通过位置调节机构在上下方向上调节与头带100的相对位置；连接线400的一端穿过头带100与另一耳机头200电性连接，另一端穿过耳罩壳体232后与发声组件电连接，连接线400位于头带100和耳罩壳体232之间的部分呈弯曲状态，故当耳罩230进行万向调节时，弯曲的连接线400就可以适应性地调整长度，从而不会对耳罩230的角度调节造成干涉或影响，使得耳罩230的角度调节更加灵活。
在一个实施例中，如图7和图8所示，拉伸臂221包括依次连接的第一连接部221a、第二连接部221b和第三连接部221c，第一连接部221a的弯曲弧度与头带100一致，并与头带100连接；第二连接部221b的两端分别与第一连接部221a和第三连接部221c连接，且第二连接部221b呈内凹的圆弧状设计；第三连接部221c与连接环222连接，并呈向外凸出的圆弧状设计。在此，耳壳220可由塑胶一体成型制 成，且拉伸臂221的波浪凹凸形设计，不但有利于耳机美观，并能有效增强耳壳220整体的结构强度，当然，第三连接部221c外凸出的圆弧状设计也可以为耳罩230连接线400的调节提供一定的避位空间。
在一个实施例中，拉伸臂221与连接环222一体设置，以便两者连接更牢固以及方便制作成型，且外表更简洁美观。
请参阅图2和图8，在一个实施例中，位置调节机构包括设于头带100的外侧面的下端的有弹性的调节卡扣224，以及设于第一连接部221a的内侧面上的沿拉伸臂221长度方向延伸的调节卡位223，调节卡位223的截面呈锯齿状，第一连接部221a通过调节卡扣224卡入调节卡位223中的不同位置，而实现相对头带100的位置调节。
在一个实施例中，连接线400位于头带100和耳罩壳体232之间的部分呈螺旋状设置。当然，于其他实施例中，该部分连接线400也可以呈其他弯曲形状设置，但在本实施例中，螺旋状的弯曲设计能够尽可能地增加连接线400的有效调节长度，达到尽量不干涉影响耳罩230的角度调节运动的技术目的。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
