在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
本公开的说明书和权利要求书中的术语“第一”和“第二”等是用来区别不同的对象，而不是用来描述对象的特定顺序。例如，第一摄像头和第二摄像头是为了区别不同的摄像头，而不是为了描述摄像头的特定顺序。
在本公开实施例中，“示例性的”或者“例如”等词来表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，此外，在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。
为了便于理解和说明，下面通过图1至图5详细地阐述本公开实施例提供的耳机结构及真无线立体声耳机。
在一个实施例中，请参考图1及图4，其为本公开实施例提供的一种耳机结构的整体示意图。该耳机结构100包括前壳组件101以及与前壳组件101相连接的后壳组件102，其中前壳组件101用于输出音频信息，而后壳组件102用于固定主板1021和天线1022。示例性地，该 后壳组件102可以包括第一容置腔1023和第二容置腔1024，而第一容置腔1023和第二容置腔1024弯折设置，比如弯折部为弧形，其中第一容置腔1023内置有主板1021，第二容置腔1024内置有天线1022，主板1021和天线1022通过线缆1025进行连接。这样设置的好处在于，一方面天线1022与主板1021间隔较远，比如距离大于2mm，此时能够对天线1022周围进行禁空处理，使得信号干扰较小，并且天线1022可以不受主板1021面积的限制而能够增加辐射面积，极大提升了天线超远距离连接性能，另一方面外形美观，同时方便抓取，增强了用户体验。
可选地，本公开一些实施例中线缆1025可以包括但不限于同轴线缆，实际装配时如图2和图3所示，天线1022通过同轴线缆一端的连接端子1026并经由该同轴线缆之后，利用该同轴线缆另一端的同轴座1027扣合到主板1021上实现连通，这样设置的好处是能够减少信号损耗，提升天线性能。
可选地，本公开一些实施例中第二容置腔1024容纳天线1022的面积为80mm 2～120mm 2，比如优选为100mm 2，由此可以兼顾天线连接性能和耳机尺寸大小，即不仅能够提升天线超远距离连接性能，还能够使得耳机小巧，便于携带。
可选地，本公开一些实施例中第二容置腔1024内部设置有支架1028，而天线1022粘贴于该支架1028上，这样设置的好处是固定牢靠，同时装配工艺简单，降低了生产成本。比如，天线1022可以包括但不限于柔性电路板(Flexible Printed Circuit，FPC)天线和激光直接成型(Laser Direct Structuring，LDS)天线中的至少一种，由此能够兼顾耳机空间和生产成本这两个因素，满足了多样化的使用需求。
可选地，如图4所示，本公开一些实施例中支架1028上与天线1022相对的位置还设置有柔性电路板1029，该柔性电路板1029通过连接器1030与主板1021电连接。比如，连接器1030可以包括但不限于板对板(Board To Board，BTB)连接器和柔性电路板连接器中的至少一种。这样设置的好处是能够充分利用耳机狭小的空间，便于小型化，方便携带，进一步提升了用户良好的体验感。
可选地，如图5所示，本公开一些实施例中柔性电路板1029上设置有主麦克风(Microphone，MIC)1031、副麦克风1032和充电柱1033，其中主麦克风1031和充电柱1033位于柔性电路板1029上远离主板1021的一端，而副麦克风1032位于柔性电路板1029上靠近主板1021的一端。这样设置的好处是一方面便于接收用户发送的语音信息，提高通信质量，另一方面可以对耳机进行充电，增加续航能力。
可选地，本公开一些实施例中后壳组件102还可以包括设置在远离前壳组件101一端的尾塞1034，由此能够对该后壳组件102进行封装，同时方便耳机充电和麦克风固定，可靠性强。
可选地，如图4所示，本公开一些实施例中前壳组件101可以包括第三容置腔，该第三容置腔内部堆叠设置有喇叭1011和电池1012，其中喇叭1011和电池1012分别与主板1021电连接，比如通过线束焊接的方式实现连接。这样设置的好处在于能够节省耳机内部狭小的空间，提高利用率。
可选地，本公开一些实施例中前壳组件101还可以包括设置在远离后壳组件102一端的耳塞1013，比如该耳塞1013与人耳道形体匹配，没有突兀感，同时为柔性材质，更加人性化。
上述耳机结构中，由于主板设置在后壳组件的第一容置腔内，天线设置在后壳组件的第二容置腔内，主板和天线之间通过线缆进行连接，而第一容置腔和第二容置腔弯折设置，由此天线和主板可以间隔较远，能够对天线周围进行禁空处理，使得信号干扰较小，同时天线可以不受主板面积的限制而能够增加辐射面积，极大地提升了天线超远距离连接性能，增强了用户体验。
在一个实施例中，本公开实施例提供了一种真无线立体声耳机，该耳机可以包括左耳机和右耳机，其中左耳机和右耳机均包括图1～图5对应实施例中任意一项的耳机结构100。
可选地，本公开一些实施例中真无线立体声耳机还可以包括充电盒，该充电盒内部设置有用于对左耳机和右耳机进行快速充电的充电组件，由此增加了耳机的续航能力。
上述真无线立体声耳机中，由于其所包括的耳机结构内主板设置 在后壳组件的第一容置腔内，天线设置在后壳组件的第二容置腔内，主板和天线之间通过线缆进行连接，而第一容置腔和第二容置腔弯折设置，由此天线和主板可以间隔较远，能够对天线周围进行禁空处理，使得信号干扰较小，同时天线可以不受主板面积的限制而能够增加辐射面积，极大地提升了天线超远距离连接性能，增强了用户体验。
以上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。
以上实施例仅表达了本公开的几种实施方式，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，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
工业实用性
本公开提供的耳机结构及真无线立体声耳机，一方面天线与主板间隔较远，比如距离大于2mm，此时能够对天线周围进行禁空处理，使得信号干扰较小，并且天线可以不受主板面积的限制而能够增加辐射面积，极大提升了天线超远距离连接性能，另一方面外形美观，同时方便抓取，增强了用户体验，具有很强的工业实用性。
