请参阅图1，图1是本申请实施例还提供的一种移动终端200，所述移动终端200包括电声装置100。可以理解的是，所述移动终端200可以是手机、平板电脑、笔记本电脑等具有发音功能的产品。为了便于描述，以移动终端200为手机为例说明，定义移动终端200的宽度方向为x向，定义移动终端200的长度方向为y向，定义移动终端200的厚度方向为z向。
请参阅图2及图3，本申请实施例一种电声装置100，包括外框体10、分隔板20、电声组件30和吸声介质40。所述外框体10具有密封腔110及与所述密封腔110导通的插孔120。吸声介质40位于密封腔110内。所述分隔板20滑动连接所述外框体10的插孔120，以使分隔板20能够位于所述密封腔110内或至少部分伸出外框体10。当所述分隔板20位于密封腔110内时，所述分隔板20阻隔所述吸声介质40并将所述密封腔110形成第一腔室111和第二腔室112，所述第二腔室111充满所述吸声介质40，第一腔室112不具有吸声介质。所述电声组件30位于所述第一腔室111中，电声组件30用于发出声波。所述吸声介质40位于所述第二腔室112中，吸声介质40用于吸收穿透所述分隔板20的声波。
由于分隔板20与外框体10为滑动连接，在组装过程中，可以先将吸声介质填40充于密封腔110中，再采用分隔板20阻隔吸声介质40，以形成充满吸声介质40的第二腔室112和收容电声组件30的第一腔室111，从而使得吸声介质40能够最大量的位于第二腔室112中，极大地提高了吸声效果，减少杂音，提升音质；而且，通过在外框体10插接分隔板20来封装吸声介质40的方式，无需将分隔板20粘胶于外框体10的内壁，这种组装方式更加方便，提高了电声装置100组装效率，且封装效果良好。
进一步地，分隔板20将密封腔110分隔成沿图中横向并排设置的第一腔室111和第二腔室112，可以避免第一腔室111和第二腔室112沿图中纵向堆 叠设置时造成的电声装置100厚度较大的问题，以提高所述电声装置100的音质的同时，还减少了电声装置100厚度，促进移动终端的轻薄化。

一种实施方式中，所述网片230具有多个网孔，所述吸声介质40为吸音颗粒，所述吸声介质40的粒径大于所述网孔的孔径。
本实施方式中，通过所述吸声介质40的粒径大于所述网孔的孔径，避免所述吸声介质40进入所述第一腔室111，从而影响所述电声组件30发声。所述分隔板20封装所述吸声介质40，使得所述吸声介质40可以完全位于第二腔室112，而不需要先对所述吸声介质40进行封装后再位于所述第二腔室112内，既提升了所述电声装置100的音质，又减少了所述电声装置100的生产成本。
请参阅图14，本申请实施例还提供了一种电声装置制作方法400，用于制作上述的电声装置100，包括以下的步骤。

404、成型电声组件30，将所述电声组件30设于所述第一腔室111。此步骤中，通过所述外框体110的安装孔117将所述电声组件30固定所述第一腔室111中。所述安装孔117位于与所述顶板113相对设置的底板114上，所述安装孔117与所述出声孔116相对设置。所述电声组件30与外框体10之间为可拆卸连接，便于在填充和封装所述吸声介质40后，安装电声组件30。进一步地，可以将电声组件30的第二盖板320与外框体110的底板114固定连接，以使电声组件30与外框体110的结构固定在一起，增加电声装置100的整体牢固性。
通过在所述外框体10的密封腔110中填充吸声介质40之后，将所述分隔板20从所述插孔120中插入密封腔110，可以分隔出填满吸声介质40的第二腔室112，并将所述吸声介质40封装于所述第二腔室112中，从而使得吸声介质40能够最大量的位于所述第二腔室112中，极大地提高了吸声效果，减少杂音，提升音质；而且，通过在外框体10插接分隔板20来封装吸声介质40的方式，无需粘胶连接，安装方便，提高电声装置100组装效率，且封装效果良好。
以上是本申请实施例的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
