具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳的实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
如图1和图2所示，在一实施例中，提供一种耳机10，耳机10可以为真正无线立体声(True Wireless Stereo，TWS)耳机，也可以为其它类型的无线耳机或者蓝牙耳机等。
如图4和图5所示，在一实施例中，耳机10包括主体20和耳柄30，主体20包括相背设置的第一侧21和第二侧22，用户使用耳机10时，主体20的第一侧21的至少部分结构能够塞于用户的耳朵内，耳柄30挂于用户的耳朵外。主体20包括第一壳体100和第二壳体200，第一侧21位于第一壳体100，第二侧22位于第二壳体200。第一壳体100和第二壳体200装配形成第一容纳空间40，第一壳体100上设有凸出的出音嘴110，出音嘴110开设有出音腔111，出音腔111与第一容纳空间40连通。如图3所示，第一容纳空间40内设有电池600、扬声器700和电路板500。耳柄30包括第三壳体300和第四壳体400，第三壳体300和第四壳体400装配形成第二容纳空间50，第二容纳空间50与第一容纳空间40连通，电路板500的部分结构延伸至第二容纳空间50内。可以理解的是，耳机10还包括天线，天线可以位于第一容纳空间40内，也可以位于第二容纳空间50内。天线可以固定于电路板500上。
如图3和图4所示，主体20具有第一方向即Y方向、第二方向即X方向和第三方向即Z方向。X方向、Y方向和Z方向两两相互垂直。主体20的长度方向沿Y方向设置，主体20的宽度方向沿X方向设置，主体20的厚度方向沿Z方向设置。主体20在XY平面上的投影大致为椭圆。主体20可以大致为椭圆体，也可以为椭圆体的部分结构。同样的，主体20也可以为其它圆滑或平滑的形状，也在本申请的保护范围之内。第一侧21和第二侧22位于主 体20的Z方向的相背设置的两侧。可以理解的是，耳柄30的厚度方向可以沿Z方向设置，耳柄30的长度方向可以与X方向和Y方向均存在一定夹角，即耳柄30的长度方向沿X方向和Y方向之间的某一方向延伸。
如图6和图7所示，在一实施例中，第二壳体200和第三壳体300为一体成型结构，第一壳体100安装于第二壳体200的一侧，第四壳体400安装于第三壳体300的一侧，即第一壳体100和第四壳体400分别位于第二壳体200和第三壳体300的相背的两侧。第二壳体200的内腔和第三壳体300的内腔连通，电路板500安装时，首先将电路板500的部分结构置于第二壳体200的内腔，移动电路板500，使得电路板500的部分结构移动至第三壳体300的内腔，然后将第四壳体400安装于第三壳体300，得到如图8所示的结构。将扬声器700和电池600安装于第一壳体100，将第一壳体100与第二壳体200装配，形成耳机10。可以理解的是，也可以首先将第四壳体400安装于第三壳体300，然后安装电路板500。
如图3和图4所示，在一实施例中，电池600和扬声器700在第一容纳空间40内沿第一方向即Y方向排列设置。电池600包括第一端610和第二端620，扬声器700包括第三端710和第四端720。可以理解的是，第一端610和第二端620为一体结构，第三端710和第四端720为一体结构。第一端610背向主体20的设置出音嘴110的一侧，第二端620朝向主体20的设置出音嘴110的一侧，即第一端610朝向第二侧22，第二端620朝向第一侧21。第三端710背向出音嘴110，第四端720朝向出音嘴110，即第三端710朝向第二侧22，第四端720朝向第一侧21。第一端610与电路板500之间贴合或存在间隙。
如图3和图4所示，在一实施例中，第一端610的外表面为圆柱状结构，第二端620为圆台状结构或类似圆台状结构，圆台状结构的直径较大的一端与圆柱状结构连接。可以理解的是，类似圆柱状结构和类似圆台状结构也在本申请的保护范围之内。第三端710和第四端720均为圆柱状结构。在XY平面上，第一端610的投影尺寸大于第二端620的投影尺寸，即第一端610的 直径大于第二端620的直径。可以理解为，第二端620为圆台状结构，随着第二端620远离第一端610，则第二端620直径越小，第二端620与第一端610结合处，第二端620的直径等于第一端610的直径。在XY平面上，第三端710的投影尺寸小于第四端720的投影尺寸，即第三端710的直径小于第四端720的直径，使得扬声器700为T形结构。
如图9所示，在一实施例中，在第一方向即Y方向上，电池600和扬声器700并排设置，第一端610和第三端710位于同一侧，第二端620和第四端720位于同一侧。第三端710为第一端610提供避让空间，第二端620为第四端720提供避让空间，使得第一容纳空间40在Y方向上得到充分使用，从而减小主体20在Y方向上的尺寸。
在一实施例中，电池600为软包电池，即在结构上采用铝塑膜包装，在发生安全隐患的情况下，软包电池最多只会鼓气裂开，而不会产生其它损害。由于圆形软包电池的生产工艺的影响，通常做出来的电池600不是均匀的圆柱形。为了充分利用空间，本申请将扬声器700做成与电池600配合的T形结构，以便充分利用空间，减小主体20在第一方向即Y方向的尺寸。
可以理解的是，主体20的长度方向即Y方向的尺寸主要由第一壳体100或第二壳体200的壁厚、电池600直径、扬声器700直径和元器件之间的间隙组成。由于壳体强度、注塑条件等因素，目前第一壳体100或第二壳体200的壁厚是确定的参数，在保证使用时间和音质的前提下，电池600和扬声器700的直径也为确定值，组装等因素也确定了组装间隙，所以通过将扬声器700的形状配合电池600的形状，以减小主体20在长度方向即Y方向的尺寸。
如图3、图10和图11所示，在一实施例中，扬声器700相对于电池600倾斜错位，以便更顺应第一容纳空间40的形状，并使得第三端710靠近电池600，在第三方向即Z方向上，第四端720凸出于第二端620。扬声器700偏离第一方向即Y方向，使得扬声器700在第一容纳腔内倾斜设置。图3中示出，在电池600固定后，通过将扬声器700倾斜设置，由于第三端710直径较小，使得扬声器700能够更进一步向电池600侧靠近，使得扬声器700在 第一方向即Y方向上占据的空间减小，节省主体20在Y方向上的空间，从而主体20在Y方向的尺寸能够减小。且扬声器700倾斜后覆盖出音腔111的朝向第一容纳空间40的一端，使得扬声器700发出的声音能够直接通过出音腔111传递出来，即扬声器700的出音方向与出音嘴110的方向保持一致，提升耳机10音质体验。
如图3所示，在一实施例中，出音嘴110具有中心轴线112，可以理解的时，中心轴线112位于出音腔111的中心。在垂直于中心轴线的平面上，第三端710的投影尺寸小于第四端的投影尺寸，即第三端的直径小于第四端的直径。在另一实施例中，扬声器700的中心线与中心轴线112平行，即中心轴线112垂直于第三端710和第四端720。再一实施例中，扬声器700的中心线与中心轴线112重合，可以理解为，中心轴线112贯穿扬声器700的中心，即扬声器700正对出音腔111，使得耳机10具有较好的音质。
扬声器700相对于电池600倾斜设置后，根据电池600和扬声器700的形状以及尺寸的设定，以及扬声器700相对于电池600的倾斜情况，电池600在XY平面上的投影和扬声器700在XY平面上的投影存在重合，从而进一步减小主体20在长度方向即Y方向上的尺寸。可以理解的是，扬声器700相对于电池600倾斜后，即使电池600在XY平面上的投影和扬声器700在XY平面上的投影不重合，由于扬声器700的倾斜设置，也同样能够减小主体20在长度方向即Y方向上的尺寸。
如图3和图12所示，在一实施例中，第一壳体100内设有定位槽120，以固定扬声器700的第四端720。定位槽120的槽壁凸出于第一壳体100的内表面。出音腔111贯穿定位槽120的槽底，使得出音腔111与第一容纳空间40连通，使得扬声器700发出的声音能够通过出音腔111传递至耳机10之外。出音腔111位于定位槽120围设的区域内，使得扬声器700的出音方向与出音嘴110的方向一致，提升用户音质体验。
在一实施例中，可以根据不同形态的耳机10的主体20的外形，专门定制异形电池600和扬声器700，充分利用扬声器700和电池600的外形特性 将主体20的外形尺寸做到最小，以减小用户使用耳机10时的压迫感，提升产品表现力。
本申请的耳机10，在保证使用时间即电池600容量和音质即喇叭直径的前提下，通过采用外形与电池600相配合的扬声器700，使得电池600和扬声器700在主体20的长度方向即Y方向上充分利用空间，以减小主体20的长度方向即Y方向的尺寸。通过将扬声器700相对于电池600倾斜错位，使得主体20的长度方向即Y方向的尺寸进一步减小，改善人机佩戴体验，做出来的耳机10的主体20的长度尺寸比市面上的同类堆叠方式长度尺寸更小，更具产品竞争力。扬声器700相对于电池600倾斜错位后，扬声器700的出音方向和出音嘴110的方向一致，提升用户音质体验。本申请的耳机10与常规堆叠方式的耳机10相比并没有增加任何成本，且还有利于扬声器700更好的发挥其音质性能。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
