Description

一种电子设备及喇叭装配壳 【技术领域】
本发明涉及通信技术领域，特别是涉及一种电子设备及喇叭装配壳。
【背景技术】
对讲机在户外使用时被淋雨或者产品浸水后，为了避免内部积水造成喇叭振膜异常使得发声异常，要求对讲机的喇叭音腔具有独立排水功能，能够自行排出水份，而不需要长时间额外晾晒，可以继续无障碍使用。其次，随着产品更新换代的变化，屏占比在终端产品中越来越重要，而户外音频的需求却越来越高，在喇叭技术没有重大突破前，整机的喇叭布局形式也要求越来越隐蔽，结构性的喇叭排水方式也需要更创新可靠。但现有的对讲机的喇叭排水结构不仅结构复杂、体积大，无法满足现在终端屏占比越来越大的需求，而且排水效果不理想，影响用户体验。
【发明内容】
本发明主要解决的技术问题是提供一种电子设备，能够解决现有技术中排水结构复杂、体积大，无法满足终端屏占比变大的需求，而且排水效果不理想，影响用户体验的技术问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种电子设备，包括喇叭装配壳、喇叭和背壳。喇叭装配壳设有喇叭装配腔、与喇叭装配腔连通的出音孔和排水通道，喇叭安装于喇叭装配腔内并面向出音孔，背壳与喇叭装配壳连接并罩盖喇叭的背部，其中，外部水从出音孔进入到喇叭装配腔时能够依次经喇叭装配壳与喇叭的正面之间的间隙、排水通道排出，所述排水通道经所述背壳的后表面引出。
其中，排水通道的截面与喇叭装配腔的截面呈L型连接并经背壳的后表面引出。
其中，喇叭安装于电子设备的上部，电子设备的上部为手持电子设备使用时朝上的一端。
其中，喇叭装配壳包括基板、装配环台和排水导管。装配环台凸设于基板 一表面以与基板共同构成所述喇叭装配腔，出音孔设于装配环台的内周贯通基板，排水导管凸设于基板一表面并位于装配环台的外侧或外端面，排水导管设有排水通道。
其中，基板设有与排水导管连通的凹陷槽，凹陷槽伸入装配环台的底部。出音孔呈弓型并靠近装配环台的内侧壁。凹陷槽设于出音孔的相对侧。背壳设有与排水导管匹配的通孔。
其中，电子设备还包括密封圈或密封胶，密封圈或密封胶设于排水导管的外侧壁与通孔的内侧壁之间以形成防水密封。
其中，电子设备包括显示屏，显示屏设于喇叭装配壳背离喇叭的一侧。喇叭装配壳背离喇叭装配腔的一侧设有凹陷区以嵌合收容装配显示屏。
其中，电子设备包括保护网，保护网设于显示屏的顶部并安装于出音孔处。电子设备为对讲机或手机。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种喇叭装配壳，包括喇叭装配腔、与喇叭装配腔连通的出音孔和排水通道，喇叭装配腔用于装配喇叭，外部水从出音孔进入到喇叭装配腔时能够依次经喇叭装配壳与喇叭的正面之间的间隙、排水通道排出，所述排水通道经所述喇叭装配壳的后表面引出。
其中，排水通道的截面与喇叭装配腔的截面呈L型连接并经喇叭装配壳的后表面引出。
其中，喇叭装配壳包括基板、装配环台和排水导管。装配环台凸设于基板一表面以与基板共同构成喇叭装配腔，出音孔设于装配环台的内周贯通基板，排水导管凸设于基板一表面并位于装配环台的外侧或外端面，排水导管设有排水通道。
其中，基板设有与排水导管连通的凹陷槽，凹陷槽伸入装配环台的底部。出音孔呈弓型并靠近装配环台的内侧壁。凹陷槽设于出音孔的相对侧。喇叭装配壳背离喇叭装配腔的一侧设有凹陷区以用于嵌合收容装配显示屏。
本发明的有益效果是：区别于现有技术的情况，本发明提供的电子设备的喇叭装配壳设有喇叭装配腔、与喇叭装配腔连通的出音孔和排水通道，使得外部水从出音孔进入到喇叭装配腔时能够依次经喇叭装配壳与喇叭的正面之间的间隙、排水通道排出，排水通道经背壳的后表面引出，由于背壳主要放置电池，可使用空间更大，排水结构设置也相对更加容易，且排水从后表面引出，可使 得电子设备的前表面的屏幕保持干燥，提升用户体验，同时无需在前表面预留喇叭排水结构，可以提升产品整体的美感，更适合于全屏化产品的堆叠结构。

【具体实施方式】
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参与图1和图2，图1是本申请的电子设备的爆炸结构示意图，图2是本申请的电子设备的剖面结构示意图。本申请提供一种电子设备，该电子设备包括喇叭装配壳100、喇叭200、背壳300和显示屏400。其中，喇叭装配壳100设有喇叭装配腔110、与喇叭装配腔110连通的出音孔120和排水通道130。喇叭200安装于喇叭装配腔110内并面向出音孔120，背壳300与喇叭装配壳100连接并罩盖喇叭200的背部。
喇叭装配壳100包括基板140、装配环台150和排水导管160。装配环台150 凸设于基板140的一表面，用来与基板140共同构成喇叭装配腔110，出音孔120在装配环台150的内周，并贯通于基板140，排水导管160凸设于基板140的一表面并位于装配环台150的外侧或外端面，并导通到背壳300的外表面，排水导管160设有排水通道130。基板140设有与排水导管160连通的凹陷槽141，凹陷槽141伸入装配环台150的底部。在外部水从出音孔120进入到喇叭装配腔110时能够依次经喇叭装配壳100与喇叭200的正面之间的间隙、排水通道130从而排出电子设备外。
在本实施例中，喇叭装配壳100与喇叭200安装于电子设备的上部，即手持电子设备使用时朝上的一端，用以在竖直放置使用时更方便利用重力排出积水。在外部水从出音孔120进入到喇叭装配腔110时，经过基板140与喇叭200的正面之间的间隙，由于水往低处流动，所以水大部分会到达基板140上的凹陷槽141，凹陷槽141与排水导管160连通，从而使得水能够通过排水导管160从背壳300的背面排出电子设备外，避免因喇叭装配腔110内部积水，造成喇叭振膜异常的发声正常。这种向后排水的喇叭结构不仅克服了侧向水道方案中在结构非常紧凑的前面板由上而下设置排水道非常困难，且使得电子设备的体积变大且影响美观的缺点，同时也克服了前向水道方案中，使用电子设备时排水易接触到用户的嘴唇，大大影响到用户的体验感。后向排水的喇叭装配壳100的排水结构，不仅不会影响喇叭200的正常组装，还可避免因喇叭200上的防水膜导致的压差，无法倒出积水的问题，使得电子设备的排水效果更好，满足用户的体验，而且排水导管160与喇叭装配壳100一体成型，使得电子设备整体的组装结构简单可靠，同时通过从背壳300的背面设置排水导管160，结构设计更加容易，且无需在出音孔120方向另外增加排水结构的位置和尺寸，可减小电子设备的体积及提升产品整体的美感，给显示屏400预留了更大的位置空间，更适用于全屏化的产品堆叠结构。
请参与图3～图6，排水通道130可设置在喇叭装配腔110的下方，排水通道130的结构有多种形式。
优选地，请参阅图3，图3是本申请的电子设备所采用的L型后表面排水结构内部排水流向的示意图。排水导管160可垂直于背壳300的方向设置，使得排水通道130的截面a与喇叭装配腔110的截面b呈L型连接(如图4左图所示)，可选地，排水导管160可倾斜于背壳300的方向设置，排水通道130的截面a与喇叭装配腔110的截面b倾斜连接(如图4右图所示)，这样更方便利用 重力进行排水。外部水从出音孔120进入到喇叭装配腔110时，并依次经过喇叭装配壳100与喇叭200的正面之间的间隙、排水通道130，经凹陷槽141，通过排水导管160从背壳300的背面排出。在本实施例中，采用的就是此种优选排水结构方式。喇叭装配壳100通过此种排水结构方式，不仅不会影响喇叭200的正常组装，如图3所示，还可以避免因喇叭200的防水膜导致的压差，无法倒出喇叭装配腔110内的积水的问题，通过排水导管160从背壳300的背面排出积水，使得电子设备的排水效果更好，满足用户的体验，而且排水导管160与喇叭装配壳100一体成型，使得电子设备整体的组装结构简单可靠，同时通过从背壳300的背面设置排水导管160，结构设计更加容易，且无需在出音孔120方向另外增加排水结构的位置和尺寸，可减小电子设备的体积及提升产品整体的美感，给显示屏400预留了更大的位置空间，更适用于全屏化的产品堆叠结构。
可选地，请参阅图5，图5本申请的电子设备所采用的L型前表面排水结构内部排水流向的示意图。当在喇叭装配壳100的前表面(即背离喇叭装配腔110的表面)设置有按键500之类的活动结构，排水通道130的截面与喇叭装配腔110的截面可呈L型连接，外部水从出音孔120进入到喇叭装配腔110时，并依次经过喇叭装配壳100与喇叭200的正面之间的间隙、排水通道130，从设置在喇叭装配壳100的前表面上的按键500的顶部排出电子设备外。
可选地，请参阅图6，图6是本申请的电子设备所采用的直线型侧表面排水结构内部排水流向的示意图。当喇叭200距离电子设备底部比较近时，排水通道130的截面与喇叭装配腔110的截面可呈直线连接，外部水从出音孔120进入到喇叭装配腔110时，并依次经过喇叭装配壳100与喇叭200的正面之间的间隙、排水通道130，从喇叭装配壳100或背壳300的侧表面排出电子设备外。
在本实施例中，出音孔120呈弓型并靠近装配环台150的内侧壁，凹陷槽141设置在出音孔120的相对侧，使得外部水从出音孔进入喇叭装配腔110后，能汇聚到凹陷槽141以便于排水。背壳300设有与排水导管160匹配的通孔310，从而使得外部水通过排水导管160从背壳300排出电子设备外。可选地，出音孔也可为其他形状，比如椭圆形或者矩形。
请参阅图2，电子设备还包括密封圈或密封胶161，密封圈或密封胶161设置在排水导管160的外侧壁与通孔310的内侧壁之间，防止从排水导管160排出的水进入背壳300，以形成防水密封。
请参阅图7～图8，图7是本申请的电子设备的喇叭装配壳的结构示意图，图8是本申请的电子设备的组合状态的结构示意图。电子设备包括显示屏400和保护网410，保护网410设于显示屏400的顶部并安装在出音孔120处。喇叭装配壳100背离喇叭装配腔110的一侧设有凹陷区170，显示屏400嵌合装配在凹陷区170内。
请参阅图9，图9是本申请的电子设备的喇叭的密封腔体音频测试图。其中，第一线条11为正常密封腔体状态下的音频曲线，第二线条12为采用排水结构设计下的音频曲线，第三线条13为采用排水结构，浸水排水后的音频曲线，从中可看出，本实施例中的电子设备采用的喇叭装配壳100的排水结构对喇叭200的音频影响不大。
本实施例提供的电子设备可为对讲机、手机或其他需要使用出音孔120的喇叭200的其他产品，如终端、车台等。
本申请还提供喇叭装配壳100的一实施方式，其中，喇叭装配壳100为上述任一实施方式所述的喇叭装配壳100。
综上所述，本领域技术人员容易理解，本申请通过在喇叭装配腔110的最低位置设计凹陷槽141，与排水导管160形成L型排水通道130，使得外部水可通过排水导管160从背壳300的后表面排出电子设备外，避免因喇叭200上的防水膜导致的压差，无法倒出积水的问题，使得电子设备的排水效果更好，而且排水导管160与喇叭装配壳100一体成型，使得电子设备整体的组装结构简单可靠，通过从背壳300的背面设置排水导管160，结构设计更加容易，且无需在出音孔120方向另外增加排水结构的位置和尺寸，可减小电子设备的体积及提升产品整体的美感，给显示屏400预留了更大的位置空间，更适用于全屏化的产品堆叠结构。
