Description

喇叭组件和电子设备
本申请要求于2016年03月16日提交中国专利局、申请号为201610150132.1、发明名称为“喇叭组件和电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电子设备的电声组件技术领域，更具体地说，涉及一种喇叭组件和电子设备。
背景技术
喇叭组件是电子设备的重要组成部分，例如智能手机、平板电脑等。该喇叭组件主要包括：喇叭前壳、喇叭后壳和喇叭振子，喇叭振子与喇叭前壳形成前腔，喇叭振子与喇叭后壳形成后腔，喇叭组件的工作性能主要取决于前腔和后腔的体积，通常后腔体积越大，喇叭组件的工作性能越好。
随着客户的需求，电子设备越来越轻薄，导致电子设备的内部设计空间越来越小，而喇叭组件的后腔为体积固定的腔，则在电子设备有限的内部设计空间内很难获得较大的后腔体积，使得喇叭组件的工作性能较差。
综上所述，如何提高电子设备中喇叭组件的工作性能，是目前本领域技术人员亟待解决的问题。
发明内容
本发明的目的是提供一种喇叭组件，提高其工作性能。本发明的另一目的是提供一种具有上述喇叭组件的电子设备。

本发明提供的喇叭组件，通过设置可变形的柔性密封袋和用于向柔性密封袋内填充介质的进口，随着介质的填充，柔性密封袋沿着电子设备内部的剩余空间发生变形，并将该剩余空间填满，由于柔性密封袋被填充介质后，柔性密封袋的容腔变大，又由于柔性密封袋的容腔、喇叭后壳和喇叭振子形成后腔，则有效扩大了后腔体积，提高了该喇叭组件的工作性能。
基于上述提供的喇叭组件，本发明还提供了一种电子设备，该电子设备包括喇叭组件，所述喇叭组件为上述任意一项所述的喇叭组件。
优选地，所述电子设备为智能手机。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本发明实施例提供的喇叭组件的爆炸图；
图2为本发明实施例提供的喇叭组件的主视图；
图3为本发明实施例提供的喇叭组件的仰视图。
上图1-3中：
1为喇叭前壳、2为喇叭振子、3为喇叭后壳、4为柔性密封袋、5为连接管、6为进管。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
如图1-3所示，本发明实施例提供的喇叭组件，包括：喇叭前壳1，喇叭后壳3，喇叭振子2，可变形的柔性密封袋4，用于向柔性密封袋4内填充介质的进口；其中，喇叭振子2与喇叭前壳1形成前腔，柔性密封袋4、喇叭后壳3与喇叭振子2形成后腔；柔性密封袋4和/或喇叭后壳3与喇叭前壳1连接。
可以理解的是，柔性密封袋4的容腔与柔性密封袋4的外形同步变形。
本发明实施例提供的喇叭组件，通过设置可变形的柔性密封袋4和用于向柔性密封袋4内填充介质的进口，随着介质的填充，柔性密封袋4沿着电子设备内部的剩余空间发生变形，并将该剩余空间填满，由于柔性密封袋4被填充介质后，柔性密封袋4的容腔变大，又由于柔性密封袋4的容腔、喇叭后壳3和喇叭振子2形成后腔，则有效扩大了后腔体积，提高了该喇叭组件的工作性能。
同时，本发明实施例提供的喇叭组件，通过改变介质的填充量来改变柔性密封袋4的容积，从而改变后腔的体积，可根据该喇叭组件的前腔体积来调节后腔体积，能够获得较好的工作性能。
同时，本发明实施例提供的喇叭组件，随着介质的填充，柔性密封袋4沿着电子设备内部的剩余空间发生变形，并将该剩余空间填满，则充分利用了电子设备内部的剩余空间，减小了占用的电子设备内部的设计空间，为获得较 薄的电子设备提供了前提。
需要说明的是，向柔性密封袋4内填充的介质可为气体、或者其他满足要求的填料。本发明实施例对介质的具体地类型不做限定。
上述喇叭组件中，喇叭前壳1与柔性密封袋4连接、喇叭前壳1与喇叭后壳3连接、或者喇叭前壳1与柔性密封袋4和喇叭后壳3连接。具体地，当喇叭前壳1与柔性密封袋4连接时，喇叭后壳3与柔性密封袋4连接；当喇叭前壳1与喇叭后壳3连接时，柔性密封袋4与喇叭后壳3连接；喇叭前壳1与柔性密封袋4和喇叭后壳3连接时，即柔性密封袋4与喇叭前壳1的一部分连接，柔性密封袋4与喇叭前壳1的另一部分连接。
为了便于安装，优先选择喇叭后壳3与喇叭前壳1相连，喇叭振子2位于喇叭前壳1和喇叭后壳3之间；喇叭振子2与喇叭后壳3形成第一后腔，柔性密封袋4的容腔形成第二后腔，第一后腔和第二后腔连通且形成后腔。
进一步地，上述柔性密封袋4与喇叭后壳3连接。当然，也可选择柔性密封袋4与喇叭前壳1连接且柔性密封袋4的容腔与前腔不连通。
为了便于安装，上述柔性密封袋4通过连接管5与第一后腔连通，如图1所示。
对于柔性密封袋4和喇叭后壳3的相对位置，可根据实际使用的电子设备的内部空间进行设计。优选地，连接管5的轴向与喇叭后壳3的厚度方向垂直。需要说明的是，喇叭后壳3的厚度方向是指，喇叭后壳3与喇叭前壳1的对接方向，即图2中的竖直方向。
为了便于生产，上述连接管5与喇叭后壳3为一体式结构。
优选地，上述进口设于喇叭后壳3，且进口通过第一后腔与柔性密封袋4的容腔连通，如图1所示。这样，方便了生产和安装；同时，介质先进入第一后腔内，也便于柔性密封袋4发生变形。当然，也可选择进口直接设在柔性密封袋4上，并不局限于上述实施例。
为了便于向柔性密封袋4内填充介质，上述喇叭组件还包括与进口连通的进管6。对于进管6的大小和长度，需要根据实际需要进行设计，本发明实施例对此不做限定。
优选地，上述进管6自远离上述进口的一端向靠近上述进口的一端渐扩， 如图3所述。可以理解的是，进管6的内径自远离进口的一端向靠近进口的一端逐渐增大。这样，可降低介质进入后腔前的流速，提高了安全可靠性。当然，也可选择进管6为等径直管，并不局限于此。
当上述进口设于喇叭后壳3时，优先选择上述进管6与喇叭后壳3为一体式结构。
进一步地，上述连接管5、进管6与喇叭后壳3为一体式结构。此时，连接管5、进管6与喇叭后壳3可通过注塑工艺获得。
上述柔性密封袋4由柔性材料制作，柔性材料种类较多，则柔性密封袋4的种类也较多，例如橡胶袋、塑料袋、乳胶袋等。为了便于取材，优先选择柔性密封袋4为乳胶袋或者塑料袋。进一步地，乳胶袋为气球。
基于上述实施例提供的喇叭组件，本发明实施例还提供了一种电子设备，该电子设备包括喇叭组件，该喇叭组件为上述任意一项所述的喇叭组件。
由于上述实施例提供的喇叭组件具有上述技术效果，上述实施例提供的电子设备具有上述喇叭组件，则上述实施例提供的电子设备也具有相应地技术效果，本文不再赘述。
上述电子设备可为笔记本电脑、平板电脑、或者智能手机等。优选地，上述电子设备为智能手机。
对所公开的实施例的上述说明，使本领域技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
