本公开涉及通信技术领域,尤其涉及一种马达及移动终端。
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

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。

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***,线圈11可以通过 胶水等方式固定于振动膜12一侧的***的区域,振动膜12另一侧的边缘区域固定于壳体3上,这样,***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***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。

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***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。
