本公开涉及通信技术领域，尤其涉及一种电子设备。
背景技术
随着电子设备的迅速发展，电子设备的密封性能越来越好。在实际的运用中，盖体与受话器之间一般具有间隙，当盖体受到外部压力时，导致间隙变小，从而导致受话器的气压急剧变化，使得受话器的气压不平衡，进而导致受话器发出的声音中会包括杂音，可见，当前受话器的发声效果较差。
发明内容
本公开实施例提供一种电子设备，以解决当前受话器的发声效果较差的问题。
为了解决上述技术问题，本公开是这样实现的：
本公开实施例提供了一种电子设备，包括：盖体、受话器、扬声器和第一腔体，所述受话器容置于所述第一腔体内，所述盖体与所述受话器以及所述扬声器之间具有间隙，所述间隙与所述第一腔体连通，所述间隙通过所述扬声器的出音孔与外界环境连通。
在本公开实施例中，电子设备包括：盖体、受话器、扬声器和第一腔体，所述受话器容置于所述第一腔体内，所述盖体与所述受话器以及所述扬声器之间具有间隙，所述间隙与所述第一腔体连通，所述间隙通过所述扬声器的出音孔与外界环境连通。这样，第一腔体可以通过间隙和出音孔与外界环境保持连通，当盖体受到外力时，第一腔体内的气压可以始终保持平衡，减少了受话器发出的声音中包括杂音的现象的发生，从而提升了受话器的发声效 果。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例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公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是本公开实施例提供的一种电子设备的结构示意图；
图2是本公开实施例提供的另一种电子设备的结构示意图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
参见图1，本公开实施例提供一种电子设备的结构示意图，如图1所示，电子设备包括：盖体10、受话器20、扬声器30和第一腔体40，所述受话器20容置于所述第一腔体40内，所述盖体10与所述受话器20以及所述扬声器30之间具有间隙50，所述间隙50与所述第一腔体40连通，所述间隙50通过所述扬声器30的出音孔60与外界环境连通。
其中，受话器20和扬声器30可以位于电子设备的不同侧面，例如：受话器20和扬声器30可以位于电子设备上相对的第一侧面和第二侧面。
其中，参见图1，当受话器20容置于第一腔体40内时，受话器20可以与第一腔体40的内壁抵接，从而可以将第一腔体40分隔为两个腔体，上述两个腔体可以分别被称为受话器20的前腔和后腔(即受话器前腔和受话器后腔)。
其中，第一腔体40与间隙50之间可以直接连通。当然，第一腔体40与间隙50之间可以设置有挡板，且挡板上可以设置有通孔，该通孔可以连通第一腔体40与间隙50。这样，挡板可以达到防水防尘的效果。
其中，间隙50的宽度在此不做限定，需要说明的是，间隙50的宽度越小越好，这样，可以降低整个电子设备的厚度。另外，盖体10与受话器20以及扬声器30之间具有间隙50可以为：盖体10与受话器20之间具有第一间隙，盖体10与扬声器30之间可以具有第二间隙，而第一间隙和第二间隙组成间隙50。需要说明的是，第一间隙和第二间隙之间是相互连通。第一间隙和第二间隙的宽度可以相同也可以不相同，具体在此不做具体限定。
其中，出音孔60的数量在此不做限定。通常电子设备上包括有多个出音孔60，且多个出音孔60中任意两个相邻出音孔60之间的距离可以相等，当然，每一个出音孔60的孔径也可以相等。出音孔60与外界环境连通，这样，可以将扬声器30发出的声音通过出音孔60传递至外界环境中，减少了扬声器30发出的声音在传递过程中的损失，从而使得扬声器30的发声效果较好。

可选的，参见图1和图2，所述电子设备还包括第二腔体70和出音通道80，所述扬声器30容置于所述第二腔体70内，所述第二腔体70与所述间隙50连通，所述第二腔体70通过所述出音通道80与所述出音孔60连通。
其中，扬声器30容置于第二腔体70内时，扬声器30可以与第二腔体70的内壁抵接，从而可以将第二腔体70分隔为两个腔体，上述两个腔体可以分别被称为扬声器30的前腔和后腔(即扬声器前腔和扬声器后腔)。
本公开实施例中，由于第二腔体70通过出音通道80与出音孔60连通，且扬声器30容置于第二腔体70内，使得扬声器30发出的声音可以通过出音通道80和出音孔60扩散至外界环境中，而声音在出音通道80和出音孔60 内传播时损失较小，从而使得声音的传播效果较好。
可选的，所述第二腔体70与所述间隙50之间设置有第一侧壁90，所述第一侧壁90上设置有第一通气孔91，所述第一通气孔91对应所述出音通道80或者所述第二腔体70设置。
其中，第一侧壁90的厚度以及第一通气孔91的孔径在此均不做限定。
另外，第一通气孔91的一端可以与间隙50连通，第一通气孔91的另一端可以与出音通道80或者第二腔体70连通。
本公开实施例中，第二腔体70与间隙50之间设置有第一侧壁90，这样，可以增强电子设备的防水防尘效果，另外，由于第一侧壁90上设置有第一通气孔91，这样，可以实现间隙50与第二腔体70之间的连通，且第一通气孔91的加工工艺简单，从而降低了加工成本。
可选的，所述第二腔体70包括扬声器前腔71和扬声器后腔72，所述扬声器前腔71和所述出音通道80连通，所述第一通气孔91分别与所述间隙50和所述扬声器前腔71连通。
其中，扬声器30可以包括膜片、单体和喇叭，扬声器30的膜片可以设置于扬声器前腔71内，且朝向第一侧壁90设置，喇叭可以对应膜片设置，单体可以设置于喇叭的一侧。另外，单体可以设置于扬声器后腔72内，喇叭用于分隔扬声器前腔71和扬声器后腔72。而第一通气孔91可以分别与扬声器前腔71和间隙50连通。
本公开实施例中，第二腔体70包括扬声器前腔71和扬声器后腔72，且扬声器前腔71和出音通道80连通，这样，使得扬声器30发出的声音可以通过扬声器前腔71、出音通道80和出音孔60传递至外界环境中，而声音在扬声器前腔71和出音通道80的损失较少，从而使得声音的传播效果较好。
可选的，所述第二腔体70包括扬声器前腔71和扬声器后腔72，所述扬声器前腔71和所述出音通道80连通，所述第一通气孔91分别与所述间隙50和所述出音通道80连通。
其中，扬声器30可以包括膜片、单体和喇叭，具体描述可以参见上个实施例。
本公开实施例中，由于扬声器30的膜片设置于扬声器前腔71内，且第 一通气孔91分别与间隙50和出音通道80连通，即第一通气孔91直接对应出音通道80设置，未对应扬声器30的膜片设置，从而不会对扬声器30的膜片的性能造成影响，进而使得扬声器30的发声效果较好。
可选的，所述电子设备还包括中框61，所述出音孔60设置于所述中框61上。
其中，出音孔60在中框61上的设置位置在此不做限定。
另外，中框61与受话器20和扬声器30之间也可以设置有间隙，且该间隙可以为间隙50的一部分。
本公开实施例中，由于出音孔60设置在中框61上，既使得出音孔60可以较好的与外界环境连通，保证了出音效果，又减轻了整个电子设备的重量。
可选的，参见图1和图2，所述出音通道80相对于所述盖体10倾斜设置。
其中，出音通道80的第一端与扬声器前腔71连通，出音通道80的第二端与出音孔60连通。而出音通道80的第一端可以靠近盖体10设置，出音通道80的第二端可以远离盖体10设置。
本公开实施例中，出音通道80相对于盖体10倾斜设置，可以减少水经出音孔60和出音通道80回流至扬声器前腔71内的现象的发生，增强了电子设备的防水效果。
可选的，参见图1和图2，所述第一通气孔91内还设置有防水透气膜92。
其中，防水透气膜92可以为一种高分子防水材料，可以采用聚四氟乙烯树脂经过拉伸等工艺方法制成，该防水透气膜92可以保证气体通过的同时阻碍液体通过。
本公开实施例中，由于第一通气孔91内还设置有防水透气膜92，从而可以阻止水等液体通过第一通气孔91进入包括有主板等器件的电子设备的内部，进而可以进一步增强电子设备的防水效果。
可选的，参见图1和图2，所述防水透气膜92设置于所述第一通气孔91靠近所述间隙50的一端。
本公开实施例中，防水透气膜92设置于第一通气孔91靠近间隙50的一端，这样，在装配的过程中，可以直接在防水透气膜92装配在第一通气孔91 靠近间隙50的一端，与装配在第一通气孔92内的方式相比，装配方式较为简单，装配效率更高，且方便后续的维修或者更换。
可选的，所述第一侧壁90上设置有多个第一通气孔91。
其中，多个第一通气孔91的孔径可以相同，也可以不相同，可选的，上述多个第一通气孔91的孔径均相同，这样，使得加工更加方便。
另外，由于多个第一通气孔91设置在第一侧壁90的不同位置，且第一侧壁90的不同位置的厚度可能不相同，则不同第一通气孔91的深度也可能不相同。
本公开实施例中，由于第一侧壁90上设置有多个第一通气孔91，与只设置一个第一通气孔91的方式相比，当某一个第一通气孔91阻塞之后，间隙50和第二腔体70之间还可以通过其他第一通气孔91进行通气，提高了通气的稳定性。
可选的，所述多个第一通气孔91等间距设置。
其中，多个第一通气孔91等间距设置，即任意相邻两个第一通气孔91之间的距离可以相等。
本公开实施例中，多个第一通气孔91等间距设置，可以使得间隙50和第二腔体70之间的通气效果较为均匀。
可选的，参见图1和图2，所述第一腔体40和所述间隙50之间设置有第二侧壁100，所述第二侧壁100上设置有第二通气孔101，所述第二通气孔101分别与所述间隙50和所述第一腔体40连通。
本公开实施例中，由于第二侧壁100上设置有第二通气孔101，第一腔体40可以通过第二通气孔101与间隙50连通，并通过间隙50、第一通气孔91和出音孔60与外界环境连通，从而使得第一腔体40内的气压可以始终保持平衡，减少了受话器20发出的声音中包括杂音的现象的发生，从而提升了受话器20的发声效果。
可选的，所述第一腔体40包括受话器前腔41和受话器后腔42，所述第二通气孔101与所述受话器后腔42连通。
其中，受话器20的单体和振膜可以均设置于受话器前腔41内。
本公开实施例中，第二通气孔101与受话器后腔42连通，可以认为整个 间隙50为受话器20的后腔的一部分，从而增大了受话器20的后腔的空间。
可选的，参见图1和图2，所述第二侧壁100上设置有两个第二通气孔101，所述两个第二通气孔101分别设置于所述第二侧壁100上相对的两侧边缘。
其中，受话器20可以相对于第二侧壁100的中心位置设置。
另外，上述两个第二通气孔101的孔径以及深度均在此不做限定。当第二侧壁100的厚度均相等时，两个第二通气孔101的深度也均相等，可选的，两个第二通气孔101的孔径也相等。
本公开实施例中，第二侧壁100上设置有两个第二通气孔101，与第二侧壁100上只设置一个第二通气孔101的方式相比，当某一个第二通气孔101阻塞之后，间隙50和第一腔体40之间还可以通过另外一个第二通气孔101进行通气，提高了通气的稳定性。另外，两个第二通气孔101分别设置于第二侧壁100上相对的两侧边缘，可以使得间隙50和第一腔体40之间的通气效果更佳均匀。
上面结合附图对本公开的实施例进行了描述，但是本公开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公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
