Description

一种线控组件及线控式蓝牙耳机 技术领域
本申请涉及耳机技术领域，特别是涉及一种线控组件及线控式蓝牙耳机。
背景技术
随着无线蓝牙技术的广泛应用，蓝牙耳机在耳机领域的占比越来越高。而目前喜欢户外运动(例如，跑步、登山、旅游等)的人群越来越多，线控式蓝牙耳机(又名，运动式蓝牙耳机)由于其轻便小巧、方便携带的特点，正成为耳机市场的新宠儿。
目前市面上对线控式蓝牙耳机的防水等级要求为IPx5(即，向线控式蓝牙耳机的外壳各个方向喷水无有害影响)。为达到IPx5等级的防水要求，一般需要将印刷电路板上的关键器件保护，同时将整片印刷电路板的表面镀上一层防水镀膜；另外，在线控式蓝牙耳机的外壳上对应通用串行总线母座的开口位置增加一通用串行总线母座盖体。
本申请的发明人在长期的研发过程中发现，目前市面上的线控式蓝牙耳机大多数进水进汗都发生在通用串行总线母座处，消费者运动时产生的汗液从通用串行总线母座处进入耳机内部后，容易产生印刷电路板腐蚀、短路等问题，严重时使整个耳机报废。
发明内容
本申请主要解决的技术问题是提供一种线控组件及线控式蓝牙耳机，能够提高线控组件的通用串行总线母座处的防水效果。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种线控组件，所述线控组件包括：第一壳体，设有连通内外空间的第一贯穿孔；印刷电路板，位于所述第一壳体内空间，与所述第一壳体设有所述第一贯穿孔的区域内表面间隔设置；防水件，夹持于所述印刷电路板与所述第一壳体设有所述第一贯穿孔的区域内表面之间，与两者的接触均密封设置，且设有连通所述第一贯穿孔的第二贯穿孔；通用串行总线母座，插设于所述第一贯穿孔和所述第二贯穿孔中，且与所述印刷电路板电连接。
为解决上述技术问题，本申请采用的另一个技术方案是：提供一种线控式蓝 牙耳机，包括耳机本体和上述任一实施例中所述的线控组件。
本申请的有益效果是：区别于现有技术的情况，本申请所提供的线控组件包括第一壳体、印刷电路板、防水件和通用串行总线母座；第一壳体设有连通内外空间的第一贯穿孔，防水件设有连通所述第一贯穿孔的第二贯穿孔，且夹持于印刷电路板与第一壳体设有第一贯穿孔的区域内表面之间，通用串行总线母座插设于所述第一贯穿孔和所述第二贯穿孔中。本申请所提供的通用串行总线母座的外围设置有防水件，外界的液体只能接触到通用串行总线母座，而不会渗透到印刷电路板上，降低印刷电路板发生腐蚀、短路等问题的概率。
在一个应用场景中，通用串行总线母座的第一端形成第一开口，第一开口远离所述印刷电路板，所述第一开口方向与所述印刷电路板垂直；该设计方式与传统的第一开口方向与印刷电路板平行的设计方式相比，需要控制的间隙减少，因虹吸效应渗透到印刷电路板上的液体的概率降低；另外，本申请所提供的第一壳体的第一贯穿孔处无需设置传统的通用串行总线母座盖体，进而使线控组件的成本降低，且充电更方便。

USB母座16插设于第一贯穿孔100和第二贯穿孔140中，且与PCBA12电连接。在一个应用场景中，USB母座16的第一端160形成第一开口162，USB母座16位于PCBA12与第一壳体10围成的空间内，USB母座16的第一开口 162远离PCBA12，且第一开口162方向与PCBA12垂直。传统的USB母座的设计为卧式，即第一开口162方向与PCBA12表面平行，本申请中USB母座的设计为立式，即第一开口162方向与PCBA12表面垂直，该立式设计方式相比卧式设计而言，需要控制的间隙减少，因虹吸效应渗透到PCBA12上的液体的概率降低；另外，本申请所提供的第一壳体10的第一贯穿孔100处无需设置传统的USB母座盖体，进而使线控组件1的成本降低，且充电更方便。
在一个实施方式中，为将USB母座16的位置固定，请参阅图6和图7，图6为图1-图5中通用串行总线母座一实施方式的结构示意图，图7为图6中图1-图5中通用串行总线母座与印刷电路板一实施方式的剖面示意图。USB母座16包括第二壳体20；第二壳体20包括前端面200、后端面202及两侧面204、206，第二壳体20的前端面200形成有第一开口162，第二壳体20的两侧面204、206朝向后端面202的方向分别延伸出至少一个固定脚208，固定脚208插置于PCBA12上相应设置的插孔300中，进而将USB母座16固定在PCBA12上。在一个应用场景中，请继续参阅图6-图7，第二壳体20两侧面204、206朝向后端面202的方向上对称设置有两个固定脚208(仅示意标出一个)，PCBA12上相应位置设置有两个插孔300(仅示意标出一个)，固定脚208插置于对应的插孔300中，进而将USB母座16固定在PCBA12上。
请继续参阅图6，在另一个实施方式中，本申请所提供的USB母座16的第二壳体20的后端面202形成有第二开口(未标示)，即第二壳体20为中空结构，第二壳体20可以是通过折弯工艺和/或五金翻边工艺制作而整体成型形成的，具有高强度、高密封性、高稳固性的特点。本申请所提供的USB母座16还包括介电板22和导电端子24；介电板22的第一端(未标示)位于第二壳体20的第二开口处，且与第二开口匹配，进而使得USB母座16形成5面封闭的结构；导电端子24包括多个金属导片，设置于介电板22上，用于传输电信号，导电端子24的一端凸伸至介电板22的第一端(未标示)外，即USB母座16外部，以便于导电端子24与PCBA12电连接，进而与PCBA12进行电信号传输。在一个应用场景中，可以利用焊接的工艺将凸伸出的导电端子24与PCBA12的对应位置处进行连接，从而实现USB母座16与PCBA12之间电连接。
在另一个实施方式中，请继续参阅图3-图4，防水件14包括第一表面142和第二表面144，其中，第一表面142面向PCBA12，PCBA12面向且对应第一表面144的区域为第一区域122，第一表面142与第一区域122的表面相互贴 合；在一个应用场景中，第一区域122的表面为平面，第一表面142也为平面，或者，第一区域122的表面具有凹部或凸部，第一表面142对应位置处也设置有与其贴合的凸部或凹部。第二表面144与第一表面142相背；第一壳体10面向第二表面144的区域为第二区域106，第一贯穿孔100位于第二区域106中，第二表面144与第二区域106的表面相互贴合；在一个应用场景中，第二区域106包括多个表面在同一平面上凸部，第二表面144与多个凸部构成的平面贴合；或者，第二表面144对应位置处也设置有与多个凸部贴合的凹部。防水件14的第二贯穿孔140贯通第一表面142和第二表面144，第二贯穿孔140的形状与USB母座16的外围匹配。
在另一个实施方式中，请继续参阅图5，为进一步固定防水件14的位置，线控组件1还包括第一背胶13，第一背胶13位于防水件14的第一表面142与PCBA12的第一区域122之间，用于将第一表面142与第一区域122的表面连接；在一个应用场景中，第一背胶13为3M不干胶，在其他应用场景中，第一背胶13也可为其他具有粘附性的材料。
在另一个实施方式中，线控组件1还包括第二背胶11，第二背胶11位于防水件14的第二表面144与第一壳体10的第二区域106的表面之间，用于将第二表面144与第二区域106的表面连接；在一个应用场景中，第二背胶11为3M不干胶，在其他应用场景中，第二背胶11也可为其他具有粘附性的材料，本申请对此不作限定。
在另一个实施方式中，请参阅图8，图8为图1-图5中防水件与第一壳体一实施方式的俯视图。防水件14(图8中斜线部分区域)还包括垂直于第一表面142、第二表面144的四个侧面146、148、141、143，第一壳体10内表面104围绕第一贯穿孔100凸设有围墙，以形成第一凹槽(未标示)，第一凹槽(未标示)包括四个侧壁A、B、C、D，防水件14的四个侧面146、148、141、143分别与第一凹槽的四个侧壁A、B、C、D贴合。在一个应用场景中，请继续参阅图3，第一凹槽中还设置有四个朝向PCBA12的柱体108(仅示意标出一个)，该柱体108与PCBA12对应位置连接固定。防水件14对应位置处设置有第三贯穿孔145(仅示意标出一个)，以使得柱体108从对应的第三贯穿孔145中伸出，而后与PCBA12连接。在某种程度上，该柱体108和第三贯穿孔145的设置能进一步固定防水件14的位置。
在又一个实施方式中，该防水件14为上述实施例中的可变形弹性材料，该 类型的防水件14在装配进线控组件1之前的高度为第一高度，防水件14在装配进线控组件1之后的高度为第二高度，第一高度大于第二高度，以使得防水件14装配进线控组件1内后，发生形变，进而使得防水件14的第二贯穿孔140内围与USB母座的外围紧密贴合。在一个应用场景中，第一高度与第二高度具有预设高度差，预设高度差为0.1-0.3mm，例如0.1mm、0.2mm、0.3mm等。
请参阅图9，图9为本申请线控式蓝牙耳机一实施方式的结构示意图，该线控式蓝牙耳机4包括耳机本体40和上述任一实施例中的线控组件42。在一个应用场景中，耳机本体40包括左耳机400和/或右耳机402，左耳机400和/或右耳机402上还分别设置有能够将其挂设于使用者耳朵上的耳挂404、406。
总而言之，本申请所提供的线控组件包括第一壳体、印刷电路板、防水件和通用串行总线母座；第一壳体设有连通内外空间的第一贯穿孔，防水件设有连通所述第一贯穿孔的第二贯穿孔，且夹持于印刷电路板与第一壳体设有第一贯穿孔的区域内表面之间，通用串行总线母座插设于所述第一贯穿孔和所述第二贯穿孔中。本申请所提供的通用串行总线母座的外围设置有防水件，外界的液体只能接触到通用串行总线母座，而不会渗透到印刷电路板上，降低印刷电路板发生腐蚀、短路等问题的概率。在一个应用场景中，通用串行总线母座的第一端形成第一开口，第一开口远离所述印刷电路板，所述第一开口方向与所述印刷电路板垂直；该设计方式与传统的第一开口方向与印刷电路板平行的设计方式相比，需要控制的间隙减少，因虹吸效应渗透到印刷电路板上的液体的概率降低；另外，本申请所提供的第一壳体的第一贯穿孔处无需设置传统的通用串行总线母座盖体，进而使线控组件的成本降低，且充电更方便。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
