在本申请实施例中，充电盒的展示面为倾斜面，当耳机放置于耳机槽时，耳机相对充电盒露出的部分较多，从而能够便于用户拿取，提高了提升用户从充电盒中拿取耳机的使用体验，同时也保证了一定的美观性，提升了产品的外观精致度。
一些可能的实现方式中，底槽的开口与顶槽的开口间隔设置。此时，底槽的开口靠近顶槽的开口的一端，低于顶槽的开口的靠近底槽的开口的一端。在本实现方式中，底槽的开口可以较大幅度地低于顶槽的开口，使得耳机放置于耳机槽时，耳机相对充电盒露出的部分更多。
一些可能的实现方式中，顶槽的底壁的最低处不低于底槽的开口的最低边缘。在本实现方式中，耳机放置于耳机槽时，耳机相对充电盒露出的部分更多。
一些可能的实现方式中，盒体具有相对设置的第一端和第二端，盒盖具有相对设置的第一端和第二端，盒盖的第一端转动连接盒体的第一端，盒盖的第二端远离盒体的第二端，以相对盒体打开，或者，盒盖的第二端靠近盒体的第二端，以相对盒体闭合。顶槽相对底槽靠近盒体的第一端。
一些可能的实现方式中，盒体的第一端高于盒体的第二端。
一些可能的实现方式中，盒体包括盒体外壳和盒体内衬，盒体内衬固定于盒体外壳的内侧，盒体内衬具有顶槽和底槽，盒体内衬的顶部相对盒体外壳凸起。此时，盒体外壳的顶面相对盒体内衬的顶面凸起，用户能够更为便捷地拿取放置于充电盒中的耳机，提高了用户体验。
一些可能的实现方式中，盒体外壳的顶面为平面，以降低盒体外壳和盒盖外壳的加工难度，也使得盒体外壳与盒盖外壳容易闭合，充电盒的分型面呈平面，充电盒的外观精致、简洁。在其他一些实施例中，充电盒的分型面也可以为曲面，本申请实施例对此不作严格限定。
盒体内衬的顶面为曲面，以使顶槽的开口和底槽的开口的形状更好地匹配和支撑耳机，此时，耳机于充电盒中的放置稳定可靠，同时也便于用户拿取，此外，也使得充电盒的展示面美观、精致。在其他一些实施例中，盒体外壳的顶面也可以为平面，本申请实施例对此不作严格限定。

关于耳机10的壳体1：
请结合参阅图1A、图1B、图6以及图7，图6是图3所示壳体1的分解结构示意图，图7是图3所示壳体1的内部结构示意图。
一些实施例中，壳体1包括主壳11和前壳12，前壳12固定于主壳11的前侧，前壳12的内部空间121与主壳11的内部空间111连通。耳机10处于佩戴状态时，前壳12朝向用户耳部，具体的，前壳12可以位于耳甲腔、接触耳甲腔，并朝向用户耳部的耳道。前壳12和主壳11的连接前壳12的部分结构形成耳机10的耳包10a的外壳，主壳11的另一部分结构形成耳机10的耳杆10b的外壳。
其中，主壳11包括第一端11a和第二端11b，主壳11的第一端11a靠近前壳12并接触前壳12，主壳11的第二端11b远离前壳12。主壳11具有脊背线112，脊背线112自主壳11的第一端11a延伸至主壳11的第二端11b。其中，脊背线112位于主壳11的后侧，脊背线112位于耳机10的中心面10c上。脊背线112为平滑的曲线。其中，如图1B所示，耳机10处于左视视角中时，主壳11的朝后一侧(也即背向前壳12一侧)的轮廓线对应于脊背线112。其中，脊背线112可以为实体线条，也可以为非实体线条，本申请实施例对此不作严格限定。
示例性的，在主壳11的第一端11a向主壳11的第二端11b的方向上，主壳11的外轮廓先收缩、后扩大。其中，主壳11的外轮廓先收缩、后扩大的情况包括：第一种情况是主壳11的外轮廓先收缩、后扩大、再收缩，第二种情况是主壳11的外轮廓先收缩、后扩大。
其中，对于第一种情况：在主壳11的第一端11a向主壳11的第二端11b的方向上，主壳11位于耳包10a的部分呈收缩形态，主壳11位于耳杆10b的部分呈现先收缩、后扩大、再收缩的形态，主壳11的底部可以由弧面或近似弧面形成底部端面，以具有圆润的形态。此时，主壳11的形状设计使得耳机10的耳杆10b能够具有与“自由垂落的水滴”近似的形状。
对于第二种情况：在主壳11的第一端11a向主壳11的第二端11b的方向上，主壳11位于耳包10a的部分呈收缩形态，主壳11位于耳杆10b的部分呈现先收缩、后扩大，也即主壳11的底部可以由平面或近 似平面形成底部端面。在第二种情况中，主壳11的底部可能存在与底部端面连接的小圆角过渡区域，这部分过渡区域的形态变化很小，可以忽略。
示例性的，如图7所示，主壳11的内部空间111包括依次连通的顶部空间111a、中部空间111b及底部空间111c，主壳11的顶部空间111a靠近主壳11的第一端11a，主壳11的底部空间111c靠近主壳11的第二端11b。主壳11的顶部空间111a连接前壳12的内部空间121。在主壳11的第一端11a向主壳11的第二端11b的方向上，主壳11的内部空间111先收缩、后扩大。主壳11的顶部空间111a的截面积基本大于主壳11的中部空间111b的截面积，主壳11的底部空间111c的截面积基本大于主壳11的中部空间111b的截面积。也即，主壳11的内部空间111中最窄的位置处于主壳11的中部空间111b中。在本实施例中，主壳11为壳件结构，主壳11的内部空间111的形态变化与主壳11的外轮廓的形态变化是相同或相近的。
可以理解的是，本申请实施例的附图中对主壳11的顶部空间111a、中部空间111b及底部空间111c的划分位置为示例性位置，并非严格的、唯一的位置划分，耳机10在整体设计上满足主壳11的内部空间111于其中部空间111b收缩到最窄即可，主壳11的顶部空间111a、中部空间111b及底部空间111c的划分位置可以根据实际情况发生适应性变化。
示例性的，脊背线112由主壳11的第一端11a向主壳11的第二端11b延伸时，脊背线112先向后延伸，后向前延伸。其中，主壳11的与脊背线112向后延伸的线段对应的部分，呈现先收缩、后扩大的形态；主壳11的与脊背线112向前延伸的线段对应的部分，呈现收缩形态。在本实施例中，通过设置脊背线112的形状，使得耳机10的背部呈现自由滑落的形态，耳机10的整体形态自然、美观。
其中，脊背线112可以包括多个平滑连接的弧线段，在脊背线112的延伸方向上，多个弧线段的半径先增加后减小。其中，半径最大的弧线段可以对应主壳11的中部空间111b设置。
一些实施例中，如图1B、图6以及图7所示，主壳11包括主壳件113和封盖件114。主壳件113具有间隔设置的第一开口1131和第二开口1132，第一开口1131和第二开口1132均朝前设置。也即，耳机10处于佩戴状态时，第一开口1131和第二开口1132均朝向用户耳部。主壳件113包括依次连接的顶部113a、中部113b及底部113c，第一开口1131形成于主壳件113的顶部113a，第二开口1132形成于主壳件113的底部113c。前壳12安装于第一开口1131，封盖件114安装于第二开口1132，封盖件114位于主壳件113的底部113c的前侧。其中，如图7所示，主壳件113的顶部113a的内侧空间形成主壳11的顶部空间111a，主壳件113的中部113b的内侧空间形成主壳11的中部空间111b，封盖件114与部分主壳件113(也即主壳件113的底部113c)共同围设出主壳11的底部空间111c。其中，主壳件113可以为一体成型的结构件，例如主壳件113可以通过注塑工艺成型。
在本实施例中，壳体1由前壳12、主壳件113及封盖件114这三个主要壳件构成，数量少，结构简单，易于组装。此外，主壳件113的中部113b为完整壳件结构，未设置开口，有利于提高主壳件113的结构强度，使得主壳11及壳体1的整体结构强度较高。
示例性的，结合参阅图1A、图6以及图7，主壳11包括抵接端面113d，抵接端面113d位于主壳件113且环绕第一开口1131设置，抵接端面113d接触前壳12。抵接端面113d所在平面垂直于耳机10的中心面10c。主壳件113在抵接端面113d所在平面上具有第一投影，封盖件114在抵接端面113d所在平面上具有第二投影，第一投影覆盖第二投影。
其中，耳机10在后视视角中的表面为主要外观面，也即由后向前看，耳机10露出的表面为主要外观面；耳机10在前视视角中的表面为次要外观面，也即由前向后看，耳机10露出的表面为主要外观面；耳机10处于佩戴状态时，次要外观面面向用户耳部、而被隐藏，主要外观面背向用户耳部，而露出。主壳件113由后向前投影形成第一投影，封盖件114由后向前投影形成第二投影，由于第一投影覆盖第二投影，在耳机10的后视视角中，主壳件113遮挡封盖件114，耳机10将封盖件114与主壳件113的分型线隐藏在次要外观面，使得耳机10的主要外观面完整，保持了良好的视觉整体感。封盖件114与主壳件113的分型线为封盖件114与主壳件113交接处于耳机10的外观面上形成的线。其中，主壳件113在左右方向上的最大轮廓线如图1B中虚线所示，封盖件114与主壳件113的分型线位于该最大轮廓线的前侧。
在一些实施例中，耳机10的整体高度可以在35mm至45mm的范围内，例如38mm、39.56mm、41.5mm、43.21mm等；耳机10的整体宽度可以在19mm至26mm的范围内，例如21mm、22.83mm、24.5mm等。主壳件113的整体高度可以在35mm至45mm的范围内，例如37mm、39.38mm、41.2mm、42.8mm等。主壳件113的底部113c的最厚处的厚度可以在8mm至12mm的范围内，例如8.2mm、9mm、9.74mm、10.11mm、10.53mm等；主壳件113的底部113c的最宽处的宽度可以在11mm至16mm的范围内，例如 12mm、12.8mm、13.53mm、14.2mm等。主壳件113在前后方向上最窄的位置处的厚度可以在6mm至8.5mm的范围内，例如6.5mm、7.2mm、7.4mm等；主壳件113在左右方向上最窄的位置处的宽度在5mm至8.5mm的范围内，例如6.47mm。封盖件114与前壳12在前后间距可以在5mm至8mm的范围内，例如5.7mm、6mm、6.54mm、7.12mm等。耳包10a的中轴10d与中心面10c的夹角可以在50°至70°的范围内，例如55°、60°、67°等。耳包10a与耳杆10b的分界线与主壳件113的抵接端面113d的夹角可以在7°至10°的范围内，例如7.6°、8.4°、9.2°等。在其他一些实施例中，耳机10的上述尺寸中一者或多者也可以依据需要进行调整。
可以理解的是，前文关于壳体1的结构描述只为示例性描述，在其他一些实施例中，壳体1也可以具有其他结构，本申请对此不做严格限定。
在上述实施例中，耳机10具有极致的空间利用率且匹配全新的外观造型，不仅能满足用户对产品的精致化、佩戴舒适性、全新的外观造型的需求；同时还能够满足用户对无线耳机10本身的音质、降噪及续航的需求。
关于充电盒：
传统的充电盒的上、下盖采用比较规则的水平展示面，耳机垂直放置在充电盒内，耳机从充电盒取出的过程受耳机露出高度、耳机磁吸力、耳机形态的影响，成为用户使用过程中的一大痛点；例如，为满足耳机入盒的磁吸力要求，耳机与充电盒之间需要满足一定的磁吸力要求，耳机拿取便捷性受到严重影响，用户体验差；而为了提升耳机拿取的便捷性，常常需要产线严格管控磁吸力大小，增加了耳机组件的成本。此外，传统耳机组件中，耳机露出充电盒部分过少，用户可拿捏的区域小，也导致了用户拿取耳机困难。
请结合参阅图8、图9、图10A及图10B，图8是本申请实施例提供一种耳机组件100在一些实施例中的结构示意图，图9是图8所示耳机组件100在另一使用状态中的结构示意图，图10A是图9所示耳机组件100的充电盒20在另一使用状态中的结构示意图，图10B是图10A所示充电盒20在另一角度的结构示意图。
一些实施例中，耳机组件100包括充电盒20、第一耳机10’以及第二耳机10”，充电盒20具有间隔设置的第一耳机槽20a和第二耳机槽20b，第一耳机槽20a和第二耳机槽20b用于收容耳机。其中，第一耳机10’能够可拆卸地容置于第一耳机槽20a，第二耳机10”能够可拆卸地容置于第二耳机槽20b。第一耳机10’和第二耳机10”中的一者为左耳机，另一者为右耳机。本实施例中，以第一耳机10’为左耳机，第二耳机10”为右耳机为例，进行举例说明。在其他一些实施例中，第一耳机10’和第二耳机10”可以互换。其中，第一耳机10’和第二耳机10”均采用前文实施例中耳机的全部结构或大部分结构。
其中，第一耳机10’的壳体1’与第二耳机10”的壳体1”为互相对称结构，第一耳机槽20a与第二耳机槽20b为互相对称结构。其中，第一耳机10’的壳体1’本身为非对称结构，第一耳机槽20a本身为非对称结构，第一耳机槽20a的形状与第一耳机10’的壳体1’的形状相同。第二耳机10”的壳体1”本身为非对称结构，第二耳机槽20b本身为非对称结构，第二耳机槽20b的形状与第二耳机10”的壳体1”的形状相同。简言之，第一耳机槽20a与第一耳机10’适配，第二耳机槽20b与第二耳机10”适配。一些示例中，当第一耳机10’装入第一耳机槽20a、第二耳机10”装入第二耳机槽20b中时，两个耳机放置正确，充电盒20可以闭合；当第一耳机10’装入第二耳机槽20b、第二耳机10”装入第一耳机槽20a中时，两个耳机放置错误，充电盒20不能闭合。
示例性的，充电盒20具有相互垂直的宽度方向、厚度方向及高度方向，第一耳机槽20a和第二耳机槽20b排布于充电盒20的宽度方向，充电盒20在高度方向上的尺寸大于充电盒20在厚度方向上的尺寸。其中，充电盒20包括盒体201和盒盖202，盒盖202转动连接盒体201。
示例性的，如图10B所示，盒体201具有相对设置的第一端201a和第二端201b，盒盖202具有相对设置的第一端202a和第二端202b，盒盖202的第一端202a转动连接盒体201的第一端201a，且转动中心平行于充电盒20的宽度方向。盒盖202的第二端202b远离盒体201的第二端201b，以相对盒体201打开，或者，盒盖202的第二端202b靠近盒体201的第二端201b，以相对盒体201闭合。盒体201的第一端201a高于盒体201的第二端201b，换言之，在充电盒20的高度方向上，盒体201的第一端201a的尺寸大于盒体201的第二端201b的尺寸。此时，盒体201的顶部整体倾斜。
请结合参阅图9和图11，图11是图9所示充电盒20的部分分解结构示意图。
