技术领域
本公开涉及通信技术领域，尤其涉及一种马达及移动终端。
背景技术
随着移动终端的快速发展，移动终端已经成为人们生活中不可缺少的通信设备。为了便于用户及时查看通信信息，当移动终端接收到通信信息时，移动终端通常会输出提示信息以提示用户，例如，移动终端振动或者移动终端输出铃声。
相关技术中，移动终端通过振动马达实现移动终端的振动，而铃声的输出则通过设置扬声器来实现。这样，由于扬声器与振动马达为两个元器件，占用移动终端内部空间较大，且在生产移动终端时，需要分别对扬声器和振动马达进行制作和安装，导致制作和安装过程繁琐。
发明内容
本公开实施例提供一种马达及移动终端，以解决移动终端的扬声器和振动马达的制作和安装过程繁琐的问题。

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马达的结构剖面图；
图2是本公开实施例提供的马达的结构爆炸图。
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，图1是本公开实施例提供的马达的结构剖面图。如图1所示，马达包括：
发音组件1、振动组件2和壳体3；
其中，所述壳体3内部具有中空腔室，所述发音组件1和所述振动组件2设于所述中空腔室内；
所述马达在接收第一电信号时，控制所述发音组件1发出声音；所述马达在接收第二电信号时，控制所述振动组件2振动。
其中，发音组件1包括具有发音功能的组件，振动组件2包括具有振动功能的组件，例如，将具备发音功能的扬声器和具备振动功能的线性马达同 时置于壳体3中；或者在壳体3设置包括线圈和振动膜的发音组件，以及包括磁体和弹性部件的振动组件。
本实施例中，将发音组件1和振动组件2同时设置于壳体内部的中空腔室内，壳体能够对发音组件和振动组件进行保护，防止发音组件和振动组件损坏。其中，壳体3可以是由一个或者多个器件组合形成，壳体3的形状具体可以根据移动终端内部的空间设计，设计为圆柱体或者长方体的形状等，提高空间利用率。另外，发音组件1和振动组件2位于壳体内，便于对马达进行安装。
上述第一电信号可以是电流频率与发音组件1的共振频率相近的电流信号，在马达接收第一电信号时，发音组件1振动发音，可以提高发音效果。第二电信号可以是电流频率与振动组件2的共振频率相近的电流信号，在马达接收第二电信号时，振动组件2的振动频率达到共振频率，可以提高振动效果。
这样，本公开的马达，通过对马达输入不同的电信号，即可以控制马达实现发音或者振动的效果，实现方式简单，能够降低生产成本。由于本公开的马达是将发音组件和振动组件合成一个器件，便于对马达进行制作和安装，能够提高生产效率，降低生产成本。
可选的，如图1和图2所示，所述发音组件1包括线圈11和振动膜12，其中，所述振动膜12的一侧固定于所述壳体3的第一位置，且与所述壳体3的第一位置之间具有间隙，所述线圈11固定于所述振动膜12的另一侧，且所述线圈11与电路板(图中未示出)电连接；
所述振动组件2包括磁体21和弹性部件22，所述弹性部件22位于所述磁体21和所述壳体3之间，且所述弹性部件22连接所述壳体3的第二位置；
所述线圈11在接收第一电信号时，控制所述振动膜12发出声音；所述线圈11在接收第二电信号时，控制所述振动组件2振动。
在该实施方式中，壳体3可以是用于容置发音组件1和振动组件2的部件，这样，壳体3能够保护发音组件1和振动组件2，且能够便于对马达进行安装。壳体3内部的构件也可以与壳体3的形状匹配，从而节约空间。
其中，振动膜12的中部区域向振动膜12的一侧隆起，线圈11可以通过 胶水等方式固定于振动膜12一侧的隆起的区域，振动膜12另一侧的边缘区域固定于壳体3上，这样，隆起的区域与壳体3之间形成一定的间隙。振动膜12的结构形式可以参见图2所示，但不限于此。线圈11还与电路板电连接，当向线圈输入电流时，线圈11振动，可以带动振动膜12振动，从而发出声音。
对于振动组件2，可以将弹性部件22的一侧连接磁体21，弹性部件22的另一侧连接壳体3。其中，磁体21的位置可以靠近线圈11的位置，且与线圈11之间具有一定间隙。这样，当磁体21振动时，不会和线圈11碰撞，能够保护磁体21和线圈11不被损伤，从而提高马达的寿命。且线圈距离磁体位置较近，磁场较强，振动效果好。
另外，壳体3的第一位置和第二位置可以是壳体3上相对的两个位置，例如，第一位置和第二位置分别位于如图1所示的壳体顶部和底部。这样，能够节约空间，且能够兼顾振动和发音的效果。
在实际操作时，将线圈11通过电路板与外电路连接。当线圈11接收第一电信号，例如，高频的电流时，线圈11产生磁场，线圈11带动振动膜12振动，从而引起周围的空气振动，发出声音。其中，第一电信号可以是电流频率与振动膜12的共振频率相近的电流信号。在第一电信号的电流频率远远高于振动组件2的共振频率的情况下，当输入第一电信号时，振动膜12的振动频率达到共振频率而发音，而振动组件2振动微弱。
当线圈11接收第二电信号时，例如，低频的电流时，线圈11产生磁场，引起磁体21振动，从而带动弹性部件22振动，进而带动移动终端振动。其中，第二电信号可以是电流频率与振动组件2的共振频率相近的电流信号，且电流频率与振动膜12的共振频率相差较大，这样，在振动组件2振动时，发音组件1不发音。
本公开实施例的马达，其是将扬声器与振动马达集成为一个器件，能够同时实现发音和振动，这样，在生产移动终端时，仅需要对马达进行制作和安装，简化制作和安装过程，能够提高生产效率，减少生产成本。

如图2所示，第一壳体31的底部为开口端，且具有腔体结构，第二壳体32连接于第一壳体31的底部，这样，第一壳体31和第二壳体32之间形成如图1所示的中空腔室，发音组件1和振动组件2设于中空腔室内。
如图1所示，振动膜12固定于壳体3的第一位置，即第一壳体31内侧的顶部，弹性部件22连接壳体3的第二位置，即第二壳体32上，且弹性部件22设于所述中空腔室内。在具体制作时，可以先将振动膜、弹性部件以及其他部件分别固定于第一壳体31和第二壳体32上，再将第一壳体31和第二壳体32连接形成中空腔室。这样，便于对发音组件1和振动组件2进行安装。
可选的，如图1和图2所示，所述振动组件2还包括质量块23，所述磁体21固定于所述质量块23上，所述质量块23连接所述弹性部件22。
在该实施方式中，当磁体21的质量较小时，可以增加质量块23，具体可以将磁体21固定于质量块23上，使得振动组件2的质量增大。质量块23连接弹性部件22，在具体实施时，可以将质量块23与弹性部件固定连接，使弹性部件22在振动时增大形变，提高振动效果。
可选的，如图1和图2所示，所述马达还包括限位块4，所述限位块4固定于所述壳体3上，且位于所述振动膜12和所述质量块23之间。
其中，限位块4的部分区域位于振动膜12和质量块23之间，这样，在振动膜12或者质量块23振动时，能够防止质量块23和振动膜12发生碰撞而损伤振动膜12，可以提高马达的寿命。
在具体实施时，可以将限位块4设于壳体3内侧的顶部，也可以将限位块4设于壳体3的内侧壁上，当质量块23或振动膜12的振动位移较大时，限位块4能够限制其位移，防止质量块23和振动膜12发生碰撞，从而保护振动膜12。

其中，弹性部件22的边缘区域可以用于连接质量块23，具体可以通过 点焊的方式将质量块23底部连接弹性部件22的边缘，可以提高连接的牢固性。弹性部件22的中部区域设有弹簧，弹簧通过点焊与第二壳体32固定连接，能够提高弹性变形效果，从而提高振动效果。
可选的，如图2所示，所述质量块23为环状结构，所述质量块23的内环侧面设有N个凹槽231；所述磁体包括N个子磁体，所述N个子磁体分别置于所述N个凹槽231内，且与所述质量块23固定连接；其中，所述N为大于1的整数。
其中，质量块23可以是圆环或者方环结构，具体可以和壳体3的结构相匹配。质量块23的内环侧面设有N个凹槽231，N个凹槽231可以均匀设于质量块23内环的侧面，每个子磁体设于一个凹槽231内，这样，可以提高振动的稳定性。另外，将磁体21设于质量块23的内部区域，一方面，磁体21靠近线圈11的位置，能够提高磁体21的振动效果；另一方面，质量块23设于弹性部件22的边缘，能够提高弹性部件22的振动效果。
可选地，当N为偶数时，将子磁体两两对称设于质量块23上，例如，如图2所示，在质量块内环侧边分别设置2对凹槽，每对凹槽对称设置。
另外，磁体21可以是磁钢，在具体实施时，可以将磁钢通过胶水固定于质量块的凹槽内，提高连接的牢固性。
可选的，如图2所示，所述线圈11为环状结构，所述线圈11可容置于所述质量块23的内环形成的空间中。
在该实施方式中，线圈11也可以是环状结构，具体形状可以和质量块23的内环结构形状匹配。其中，线圈11的外环小于质量块23的内环，当线圈11或者质量块23振动时，线圈11可以容置于质量块23内，线圈11和质量块23之间不会发生碰撞，能够保护线圈11，且能够节约空间。
可选的，如图2所示，所述振动膜12的中间区域为平面，所述线圈11固定于所述振动膜12的中间区域。
在该实施方式中，振动膜12的中部区域为平面，当振动膜12和壳体3连接时，平面区域和壳体3之间形成间隙。另外，线圈11固定于振动膜12的中间区域，能够提高振动膜12的振动效果，且振动膜12和壳体3之间形成的间隙便于振动膜12振动。
可选的，所述壳体3在与所述振动膜12的中间区域对应的部位设有出声孔33。
如图2所示，壳体3上设有出声孔33。由于出声孔33的位置对应于振动膜12隆起的中间区域，振动膜12的中间区域振动时发音，并通过出声孔33发出，能够提高发音效果。
本公开实施例的马达，将扬声器与振动马达集成为一个器件，能够同时实现发音和振动的双重功能，能够集成零件，减少零件数目，降低制作成本。
本公开实施例还提供一种移动终端，该移动终端包括如上任一实施方式中的马达。由于该移动终端具有上述马达，因此，该移动终端具有同上述任一实施方式中的马达相同的有益效果，为避免重复，此处不再赘述。该移动终端具有上述马达，能够简化移动终端的安装和制作过程，提高生产效率，降低移动终端的生产成本。
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。
