技术领域
本申请属于电子产品技术领域，具体涉及一种电子设备。
背景技术
近年来，电子设备迅猛发展，为了给使用者更好的使用体验，一些电子设备配置了双扬声器，以提升音效品质。双扬声器的电子设备基本是以听筒受话器作为增加的第二扬声器。听筒受话器需要具有足够大的音腔体积，以达到较佳的音效品质，但较大的音腔体积会与电子设备的轻薄化发展以及电子设备内部电子元器件的紧凑布局产生矛盾。
发明内容
本申请实施例的目的是提供一种电子设备，能够解决电子设备音效品质与外观轻薄化无法兼得的问题。
为了解决上述技术问题，本申请是这样实现的：
本申请实施例提供了一种电子设备，该电子设备包括：
壳体组件，所述壳体组件包括可相对移动的第一壳体和第二壳体；

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，所描述的实施例是本申请一部分实施例，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作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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例进行详细地说明。
本申请实施例公开了一种电子设备，所公开的电子设备包括壳体组件100、柔性屏200和扬声器300。
壳体组件100为电子设备的基础安装构件，其可以为柔性屏200、扬声器300等器件提供安装基础。本申请实施例中，壳体组件100包括第一壳体110和第二壳体120，且第一壳体110和第二壳体120可相对移动，以实现壳体组件100的伸缩运动。可选地，第一壳体110和第二壳体120之间可以设置滑动结构，如滑轨、滑槽、滑杆等结构，通过上述滑动结构可以起到导向作用，从而保证第一壳体110与第二壳体120相对移动的精度和稳定性。
柔性屏200为电子设备的显示构件，其可以用于显示信息、图像、视频等内容，还可以供用户触摸操控。本申请实施例中，柔性屏200设置于壳体组件100，且柔性屏200能够随第一壳体110和第二壳体120的相对移动而展开或收合。可选地，柔性屏200的一端可运动地设置于第一壳体110，另一端固定于第二壳体120。在一些实施例中，可以在第一壳体110内设置牵引装置，柔性屏200的一端与牵引装置相连，如此，在第一壳体110与第二 壳体120相对伸展时，牵引装置释放部分柔性屏200，以使柔性屏200随着第一壳体110和第二壳体120的伸展而展开；在第一壳体110与第二壳体120相对收缩时，牵引装置牵引柔性屏200，以使柔性屏200随着第一壳体110和第二壳体120的收缩而收合。
扬声器300为电子设备的发声构件，通过扬声器300可以使电子设备释放声音，例如，放音乐、放视频等。本申请实施例中，扬声器300设置于第一壳体110，其中，扬声器300包括可变音腔320，可变音腔320与第二壳体120连接，且可变音腔320的体积能够随第一壳体110和第二壳体120的相对移动而增大或减小。由于音腔的大小对于音质产生一定影响，本申请实施例中，通过改变音腔体积的大小以提升音质。
本申请实施例提供的电子设备，通过可变音腔320可以扩展扬声器300的腔体的体积，并且，该电子设备为一种屏幕可伸缩的电子设备，柔性屏200可以在第一壳体110和第二壳体120相对移动时随着展开或收合，从而使显示区域的面积增大或缩小，当柔性屏200展开时，可以为用户提供更大的显示区域，以方便用户观看或操作，提升了用户体验；当柔性屏200收合时，可以使电子设备的整体体积较小，以方便用户携带、收纳或把持。在第一壳体110和第二壳体120相对移动的过程中，可变音腔320的体积也随之变化，如此，在第一壳体110与第二壳体120相对伸展时，可变音腔320的体积增大，直至第一壳体110与第二壳体120完全伸展，此时可变音腔320的体积达到最大，从而可以使声音播放水平更加优秀，以为用户提供更好的听觉体验；在第一壳体110与第二壳体120相对收缩时，可变音腔320的体积减小，直至第一壳体110与第二壳体120完全收缩，可变音腔320的体积达到最小，此时可变音腔320也可以满足普通场景的播放和音质水平。
基于上述设置，本申请实施例中，柔性屏200与可变音腔320均可以随第一壳体110和第二壳体120的相对移动而产生变化，如此，可以实现在柔性屏200处于展开状态的同时可变音腔320体积最大，从而可以同时实现更 大的显示区域和更优秀的声音播放水平，进而给用户提供更好的视听体验；另外，在柔性屏200处于收合状态的同时可变音腔320的体积最小，此时可以实现基本的显示功能和满足普通场景的播放和音质水平。
相比于电子设备中采用足够大体积的音腔来提高音效品质的方式，本申请实施例中的可变音腔320的体积可随着用户需求改变体积，从而无需在电子设备中直接设置较大体积的音腔，进而不会影响电子设备的轻薄化发展，并且可变音腔320不会影响电子设备内部电子元器件的布局。因此，有效解决了电子设备中存在的较大的音腔体积与电子设备的轻薄化发展以及电子设备内部电子元器件的紧凑布局产生矛盾的问题。
参考图3至图5，在一些实施例中，可变音腔320包括第一音腔321和第二音腔322，且第一音腔321可相对于第二音腔322移动。可选地，第一音腔321与第二音腔322滑动连接，通过第一音腔321和第二音腔322相对滑动，可以实现可变音腔320体积的变化。第一音腔321与第一壳体110连接，第二音腔322与第二壳体120连接。基于此，在第一壳体110与第二壳体120相对移动的过程中，会带动第一音腔321与第二音腔322相对移动，从而改变可变音腔320的体积。可选地，第一音腔321和第二音腔322可以相互套接设置，也即，一者的至少部分位于另一者内部，且可以相对移动。除此以外，还可以是两者之间通过连接件实现连接，该连接件可变形，从而在第一音腔321和第二音腔322相对移动时，连接件可发生变形，既能够将第一音腔321和第二音腔322连接在一起，又可以保证第一音腔321与第二音腔322相对移动。进一步地，第一音腔321的内腔与第二音腔322的内腔连通。基于此，扬声器300产生的声音能够充斥在第一音腔321的内腔与第二音腔322的内腔中，从而使声音能够在更大体积的腔体内回荡，在一定程度上提升了音质水平。
参考图5和图7，在一些实施例中，第二壳体120与第二音腔322中的一者设有第一限位块410，第一限位块410上形成有限位槽411，另一者设有 第一限位齿510，且第一限位齿510与限位槽411卡接配合。可选地，第一音腔321与第一壳体110固定连接，第二音腔322与第二壳体120之间通过卡接配合的限位槽411和第一限位齿510实现固定。
可选地，第二音腔322沿第二方向的两侧分别设有第一限位齿510，该第二方向与第一壳体110及第二壳体120相对移动的方向垂直。相应地，第二壳体120的朝向第二音腔322的表面沿第二方向间隔设有两排第一限位块410，每排包括至少一个第一限位块410。每个第一限位块410上对应开设有限位槽411。当第二音腔322装配于第二壳体120时，第一限位齿510对应嵌设于限位槽411中，通过限位槽411可以限制第一限位齿510移动，从而通过限位槽411与第一限位齿510之间的卡接配合，实现了第二音腔322与第二壳体120之间的卡接固定，以使第二音腔322能够随着第二壳体120同步移动。
当然，除了上述实施方式之外，还可以通过其他固定方式将第二音腔322固定于第二壳体120。例如，两者之间通过紧固螺钉实现固定，还可以采用焊接、粘接等方式实现固定。本申请实施例中不限制第二音腔322与第二壳体120之间的具体固定方式，只要满足第二音腔322能够随第二壳体120移动即可。
由于第一音腔321与第二音腔322可以随着第一壳体110和第二壳体120的伸展或收缩而改变体积，为了防止在第一壳体110与第二壳体120伸展过程中第一音腔321与第二音腔322相对脱离而导致可变音腔320遭到损坏，以及第一壳体110与第二壳体120收缩过程中第一音腔321与第二音腔322相互挤压而遭到损坏，本申请实施例中增设了限位结构。
进一步考虑到一些电子设备中的第一壳体110与第二壳体120相对移动的距离较大，而第一音腔321与第二音腔322之前相对移动的距离较小，在第一壳体110与第二壳体120相对伸展时，有可能使第一音腔321与第二音腔322脱离，从而导致可变音腔320遭到损坏。基于此，本申请实施例中将 第一壳体110与第二壳体120相对移动的过程分为有效行程和空行程，当第一壳体110与第二壳体120在有效行程内相对移动时，第一音腔321与第二音腔322也会随着相对移动，当第一壳体110与第二壳体120在空行程内相对移动时，第一音腔321与第二音腔322不会相对移动。
参考图8和图9，在一些实施例中，第二壳体120与第二音腔322滑动连接，且两者中的一者设有沿第一方向间隔设置的第二限位块420和第三限位块430，另一者设有第二限位齿520，其中，第二限位齿520可移动地设置于第二限位块420和第三限位块430之间，第一方向与第一壳体110及第二壳体120相对移动的方向平行。可选地，第二音腔322沿第二方向的两侧分别设有第二限位齿520，相应地，第二壳体120的朝向第二音腔322的表面沿第二方向设有两排限位块，且每排包括沿第一方向间隔设置的第二限位块420和第三限位块430，第二限位块420与第三限位块430之间的间隔大于第二限位齿520在第一方向上的尺寸，从而可以保证第二限位齿520可以在第二限位块420和第三限位块430之间移动。当第二音腔322装配于第二壳体120时，第二限位齿520位于第二限位块420与第三限位块430之间，通过第二限位块420与第三限位块430可以分别从两个方向限制第二限位齿520的移动范围。
基于上述设置，在第一壳体110与第二壳体120相对伸展时，在初始一段时间内，也即，在空行程范围内，第二限位齿520在第二限位块420和第三限位块430之间移动，此过程中第二音腔322相对于第二壳体120滑动，且第一音腔321与第二音腔322相对静止，因此，可变音腔320的体积不变。与此同时，在空行程中，柔性屏200会随着第一壳体110与第二壳体120的相对伸展而适应性展开，以增大显示区域面积。随着第一壳体110与第二壳体120继续相对伸展，当第三限位块430触碰到第二限位齿520时，第三限位块430会挤压第二限位齿520，从而使第二壳体120带动第二音腔322同步移动，此时开始进入有效行程。在有效行程范围内，第一音腔321与第二 音腔322会随着第一壳体110与第二壳体120的相对伸展而伸展，从而使可变音腔320的体积增大，直至第一壳体110与第二壳体120完全伸展开。与此同时，在有效行程中，柔性屏200会随着第一壳体110与第二壳体120的相对伸展而继续展开，以使显示区域面积增大。当第一壳体110与第二壳体120完全伸展时，可变音腔320的体积最大，柔性屏200的显示区域面积最大，从而可以为用户提供较佳的视听体验。
相反，在第一壳体110与第二壳体120相对收缩的过程中，首先进入空行程范围，此过程中第二限位齿520在第二限位块420与第三限位块430之间移动，使得第二壳体120不会带动第二音腔322移动，从而使可变音腔320的体积不发生变化。在此过程中，柔性屏200会随着第一壳体110与第二壳体120的相对收缩而适应收合，以减小显示区域面积。随着第一壳体110与第二壳体120继续相对收缩，当第二限位块420触碰到第二限位齿520时，第二限位块420会挤压第二限位齿520，从而使第二壳体120带动第二音腔322同步移动，此时开始进入有效行程。在有效行程范围内，第一音腔321与第二音腔322会随着第一壳体110与第二壳体120的相对收缩而收缩，从而使可变音腔320的体积减小，直至第一壳体110与第二壳体120完全收缩。与此同时，在有效行程范围内，柔性屏200会随着第一壳体110与第二壳体120的相对收缩而继续收合，以使显示区域面积减小。当第一壳体110与第二壳体120完全收缩时，可变音腔320的体积最小，柔性屏200的显示区域面积最小，从而可以在保证基本视听需求的情况下保持电子设备小巧的特征，便于携带和把持。
参考图10和图11，在另一些实施例中，电子设备还包括连杆组件，该连杆组件包括相互铰接的第一连杆530和第二连杆540，第一连杆530与第二壳体120铰接，第二连杆540与第二音腔322铰接，第二壳体120与第二音腔322滑动连接。可选地，第一连杆530的一端与第二壳体120之间通过转轴或销钉连接，第一连杆530的第二端与第二连杆540的第二端之间通过 转轴或销钉连接，第二连杆540的第一端与第二音腔322之间通过转轴或销钉连接。如此，在第二壳体120与第二音腔322之间相对移动时，第一连杆530和第二连杆540之间可以相对摆动，从而适应第二壳体120与第二音腔322的相对移动。为了保证第二壳体120与第二音腔322之间连接的稳定性，本申请实施例中在第二音腔322的沿第二方向的两侧分别设置一排连杆组件，且每排包括至少一组连杆组件。当第二音腔322装配于第二壳体120时，连杆组件连接在第二音腔322与第二壳体120之间。
基于上述设置，在第一壳体110与第二壳体120相对伸展时，在初始一段时间内，也即，在空行程范围内，第一连杆530与第二连杆540相对摆动，此过程中第二音腔322相对于第二壳体120滑动，并使第二音腔322与第一音腔321相对静止，因此，可变音腔320的体积不变。与此同时，在空行程中柔性屏200会随着第一壳体110与第二壳体120的相对伸展而适应性展开，以增大显示区域面积。随着第一壳体110与第二壳体120继续相对伸展，当第一连杆530与第二连杆540之间共线或近似于共线时，两者则无法继续相对摆动，第二壳体120通过第一连杆530拉动第二连杆540，并由第二连杆540拉动第二音腔322同步移动，此时开始进入有效行程。在有效行程范围内，第一音腔321与第二音腔322会随着第一壳体110与第二壳体120相对伸展而伸展，从而使可变音腔320的体积增大，直至第一壳体110与第二壳体120完全伸展开。与此同时，在有效行程范围内，柔性屏200会随着第一壳体110与第二壳体120的相对伸展而适继续展开，以使显示区域面积增大。当第一壳体110与第二壳体120完全伸展时，可变音腔320的体积最大，柔性屏200的显示区域面积最大，从而可以为用户提供较佳的视听体验。
相反，在第一壳体110与第二壳体120相对收缩的过程中，首先进入空行程范围，此过程中第一连杆530与第二连杆540相对摆动，使得第二壳体120不会带动第二音腔322移动，从而使可变音腔320的体积不发生变化。在此过程中，柔性屏200会随着第一壳体110与第二壳体120的相对收缩而 适应收合，以减小显示区域面积。随着第一壳体110与第二壳体120继续相对收缩，当第一连杆530与第二连杆540之间无法继续相对摆动时，第二壳体120开始通过第一连杆530和第二连杆540带动第二音腔322同步移动，此时开始进入有效行程。在有效行程范围内，第一音腔321与第二音腔322会随着第一壳体110与第二壳体120的相对收缩而收缩，从而使可变音腔320的体积减小，直至第一壳体110与第二壳体120完全收缩。与此同时，在有效行程范围内，柔性屏200会随着第一壳体110与第二壳体120的相对收缩而继续收合，以使显示区域面积减小。当第一壳体110与第二壳体120完全收缩时，可变音腔320的体积最小，柔性屏200的显示区域面积最小，从而可以在保证基本视听需求的情况下保持电子设备小巧的特征，便于携带和把持。
参考图6，为了使可变音腔320的体积可调，本申请实施例中的可变音腔320还可以包括第三音腔323。其中，第三音腔323设置于第一音腔321与第二音腔322之间，并将第一音腔321和第二音腔322连接，与此同时，还将第一音腔321和第二音腔322连通，第三音腔323为弹性音腔。可选地，第三音腔323可以采用弹性囊管的形式。由此，第三音腔323在受到作用力时，可以发生弹性变形，且在弹性变形后同样可以将第一音腔321和第二音腔322连通。
基于上述设置，当第一壳体110与第二壳体120相对伸展时，第一音腔321与第二音腔322随着第一壳体110与第二壳体120的相对伸展而伸展，此时第一音腔321与第二音腔322相对远离，从而将第三音腔323拉长。随着第三音腔323的拉长，使得第一音腔321、第三音腔323和第二音腔322三者共同组成的可变音腔320的体积增大，以便于提升音质。相反，当第一壳体110与第二壳体120相对收缩时，第一音腔321与第二音腔322随着第一壳体110与第二壳体120的相对收缩而收缩，此时第一音腔321与第二音腔322相对靠近，第三音腔323弹力恢复。随着第三音腔323弹力恢复，使 得第一音腔321、第三音腔323和第二音腔322三者共同组成的可变音腔320的体积减小，以满足基本音质要求。
考虑到一些实施例中可变音腔320包括相对移动的第一音腔321和第二音腔322，并保证在第一壳体110与第二壳体120相对移动的过程中第一音腔321与第二音腔322形成的内腔与外界不连通，本申请实施例中将第一音腔321与第二音腔322套接在一起，从而既满足两者的相对移动，又使两者不会脱离，且保证时刻连通。参考图4，第一音腔321包括相连或一体设置的容纳部3211和滑动部3212，其中，容纳部3211和滑动部3212具有连通的腔体，扬声器单体310(即，发声元件)设置在容纳部3211的腔体中，第二音腔322可移动地套设在滑动部3212的外侧，且第二音腔322的内腔与容纳部3211和滑动部3212的腔体连通。如此，扬声器单体310发出的声音可以在第一音腔321和第二音腔322形成的可变音腔320的内腔中回荡。
进一步地，在容纳部3211的侧壁上开设出声孔3213。可选地，将扬声器单体310与出声孔3213相对设置。通过出声孔3213可以将扬声器单体310发出的声音向外界传播，以供用户聆听。
由于第二音腔322套设于滑动部3212，并可相对于滑动部3212移动，考虑到第二音腔322的内壁与滑动部3212的外壁之间存在间隙导致声音从间隙处外传，而影响音质，本申请实施例中在滑动部3212与第二音腔322之间设置用于密封两者的密封件330。继续参考图4，密封件330可以是密封环，其套设在滑动部3212的外壁上。另外，可以根据实际需求在滑动部3212与第二音腔322之间设置至少一个密封件330，以达到良好密封的效果。密封件330可以采用可压缩的弹性密封材料制成，其在滑动部3212与第二音腔322之间可以发生压缩变形，从而分别抵紧滑动部3212的外壁和第二音腔322的内壁，进而提升了密封效果。
在可变音腔320的体积增大或减小时，考虑到可变音腔320内部与外界气压差而阻碍可变音腔320体积变化的问题，本申请实施例中，可变音腔320 的侧壁上设有气压平衡阀340。参考图3和图6，气压平衡阀340安装在第二音腔322的侧壁上。通过气压平衡阀340可以在可变音腔320的体积增大或减小过程中平衡内外侧气压，从而缓解内外压差影响音质或者阻碍可变音腔320体积的变化。
参考图3、图4和图6，为了使柔性屏200能够适应第一壳体110与第二壳体120的伸展或收缩，本申请实施例中还设置了卷轴600，通过卷轴600可以在第一壳体110与第二壳体120相对伸展时释放柔性屏200，并在第一壳体110与第二壳体120相对收缩时储存柔性屏200。可选地，卷轴600设置于第一壳体110，例如，卷轴600设置在第一壳体110内侧，并位于远离第二壳体120的一端。卷轴600可以相对于第一壳体110转动，以通过卷绕的方式实现释放或储存柔性屏200。进一步地，柔性屏200包括相背设置的第一端和第二端，其中，第一端卷绕于卷轴600，第二端固定于第二壳体120。
基于上述设置，在第一壳体110与第二壳体120相对伸展的过程中，卷轴600释放柔性屏200，此时第二壳体120同步拉动柔性屏200的第二端，以使柔性屏200展开。在第一壳体110与第二壳体120相对收缩的过程中，卷轴600卷绕柔性屏200的第一端，以适应第一壳体110与第二壳体120相对收缩的过程，从而可以防止柔性屏200褶皱不平。
本申请实施例中，柔性屏200设置于壳体组件100上，在第一壳体110与第二壳体120相对伸展的过程中，为了防止第一壳体110与第二壳体120相互分离而失去对柔性屏200的支撑作用，本申请中的第一壳体110与第二壳体120之间采用交叉的方式布置。参考图12和图13，在一些实施例中，第一壳体110包括第一支撑架111和分别设置于第一支撑架111两端的第一横梁112，相应地，第二壳体120包括第二支撑架121和分别设置于第二支撑架121两端的第二横梁122。其中，第一支撑架111与第二支撑架121之前采用梳齿交错排列方式滑动连接，第一横梁112与对应设置的第二横梁122滑动连接。可选地，第一支撑架111包括多个间隔设置的条形结构，相连两 个条形结构之间形成间隔腔，同样地，第二支撑架121包括多个间隔设置的条形结构，相邻两个条形结构之间形成间隔腔。在第一壳体110与第二壳体120装配后，第一支撑架111的条形结构对应插设于第二支撑架121的间隔腔中，第二支撑架121的条形结构对应插设于第一支撑架111的间隔腔中。如此，在第一壳体110与第二壳体120相对伸展或收缩时，条形结构在所对应的间隔腔中移动，从而使第一壳体110与第二壳体120之间不会相互分离。
为了使柔性屏200更加平整，将第一支撑架111的条形结构的与柔性屏200相对的表面与第二支撑架121的条形结构的与柔性屏200相对的表面平齐设置，也即，在同一平面，从而能够保证柔性屏200的平整度。
参考图15，第一横梁112与第二横梁122滑动连接。可选地，两者中的一者可以设置滑槽或滑轨，另一者与滑槽或滑轨滑动连接，从而可以保证第一壳体110与第二壳体120相对伸展或收缩。
为了使第一壳体110与第二壳体120相对伸展或收缩，以实现柔性屏200的展开或收合，以及可变音腔320体积的增大或减小，本申请实施例中增设了驱动装置700，该驱动装置700用于驱动第二壳体120相对于第一壳体110移动。可选地，驱动装置700可以包括电机、丝杆、滑块等结构，电机通过丝杆带动滑块移动，从而驱动第二壳体120相对于第一壳体110移动。当然，驱动机构还可以包括电磁件和永磁件，在以不同形式通电时，电磁件与永磁件相互作用，实现相吸或相斥，从而驱动第二壳体120相对于第一壳体110移动。除上述方式之外，还可以是其他方式，本申请实施例中对于驱动装置700的具体形式不作限定。
综上所述，本申请实施例中的电子设备能够同时实现大屏和较佳的音质，从而为用户提供较佳的视听体验，并且还能够实现基本的显示功能和满足普通场景的音质水平。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的， 本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
