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描述，显然，所描述的实施例仅仅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做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。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本实施例公开了一种喇叭与马达的组合结构，结合图1所示，本实施例的喇叭与马达的组合结构包括前盖1和后壳2，前盖1和后壳2构成容纳腔。盆架3设在容纳腔内，并将容纳腔分割为第一腔室4和第二腔室5，其中盆架3与前盖1围成的空间为第一腔室4，盆架3与后壳2围成的空间为第二腔室5。喇叭设置于第一腔室4内，马达设置于第二腔室5内。
其中，结合图1所示，马达包括马达线圈7、配重磁钢8和刚性支架9；马达线圈7绕制在位于第二腔室5中的盆架3上。配重磁钢8与刚性支架9连接，且刚性支架9装配在盆架3的背面，配重磁钢8设置在马达线圈7和后壳2之间，其中通过刚性支架9固定在盆架3上能够对配重磁钢8起到支撑的作用；
动圈式喇叭包括盆架3，还包括磁铁10、华司11、振膜12和喇叭线圈 13；盆架3和华司11分别设置在磁铁10的两侧，而喇叭线圈13设置在盆架3与磁铁10之间的磁场间隙中，且振膜12与喇叭线圈13连接。其中，磁铁10用于产生磁场，并通过盆架3和华司11的传导使该磁场为均匀磁场。喇叭工作时，对喇叭线圈13输入音频电信号，输入音频电信号后的喇叭线圈13在均匀磁场中受力并产生振动，喇叭线圈13的振动带动振膜12产生振动，进而通过振膜12推动空气发声。
马达和喇叭共用盆架3，其中，通过将马达线圈7缠绕在盆架3上，并利用盆架3固定刚性支架9，且盆架3还能对磁铁10的磁场进行传导；进而减少零部件的使用，并达到节约空间的效果。
喇叭和马达被设计成各自独立接入电信号，这样喇叭和马达不仅各自能够单独工作，还能够实现共同工作，方便用户根据使用场景的不同选择马达和喇叭的工作模式。
并且，盆架3的中心设有连通第一腔室4和第二腔室5的第一通孔6。通过盆架3上的第一通孔6连通马达和喇叭所在的空间，当喇叭和马达均工作的时候，通过控制二者振动方向同步，达到互相增强振动的效果，提高喇叭的音量并增强马达的振感。
具体地，当喇叭工作时，推动第一腔室4内的空气振动，第一腔室4内的空气振动进一步通过第一通孔6推动第二腔室5内的空气振动，从而加强马达的振动幅度，增强马达振感。当马达工作时，推动第二腔室5内的空气振动，第二腔室5内的空气振动进一步通过第一通孔6推动第一腔室4内的空气振动，从而加强喇叭振膜12的振动幅度，提高喇叭的音量。
进一步的，配重磁钢8与刚性支架9通过粘结进行连接，从而使配重磁钢8在第二腔体中正常振动。
结合图1所示，喇叭的振膜12与前盖1之间构成喇叭工作时的前声腔，前盖1设有出音孔101。振膜12在振动过程中推动前声腔中的空气发声，并进一步通过出音孔101将声音对外传播。喇叭的振膜12与后壳2之间构成喇叭工作时的，后壳2设有泄气孔21。利用泄气孔21将后声腔中的空气排出，从而降低后声腔空气中的振动阻尼，增强喇叭的发声音量。
本申请的一个实施例中，仍结合图1所示，配重磁钢8的中心设有第二通孔81，且第二通孔81和盆架3的第一通孔6相连通。利用第二通孔81将 喇叭的后声腔与马达所在的第二腔室5相连通，扩充了喇叭工作时的后声腔，可以进一步提高喇叭在低音频段的音质，同时还可以对配重磁钢8的线性振动起到均衡压力的作用。
本申请的一个实施例中，刚性支架9设有多个，相邻刚性支架9彼此间隔设置。通过刚性支架9之间的间隔使喇叭的后声腔与第二腔室5相连通的途径增多，防止第二通孔81堵塞后造成喇叭后声腔的密闭，影响到喇叭的音质，并且还能够避免由于金属热胀冷缩会导致刚性支架9的永久变形或损坏。
本申请的一个实施例中，马达为线性马达。线性马达的结构简单，其动力是通过空气传递的，可以减少机械接触，降低线性马达内零件间的摩擦，从而增加马达的寿命。该线性马达工作时，对马达线圈7输入交变的电信号，使马达线圈7产生周期性变化的电磁场。在电磁场的作用下，配重磁钢8在第二腔室5中线性振动，进而使该喇叭与马达的组合结构产生振感。
本申请的一个实施例中，喇叭采用动圈式结构设计，动圈式喇叭具有高灵敏度和低失真的优点。结合图1所示，喇叭工作时，对喇叭线圈13输入音频电信号，输入音频电信号后的喇叭线圈13在均匀磁场中受力并产生振动，喇叭线圈13的振动带动振膜12产生振动，进而通过振膜12推动空气发声。
本申请的一个实施例中，结合图1所示，盆架3上还设有第三通孔31，第二腔室5与喇叭线圈13振动所在的磁场间隙之间通过第三通孔31连通。在喇叭工作的过程中，利用第三通孔31将喇叭线圈13振动所在的磁场间隙与马达所在的第二腔室5相连通，扩充了喇叭工作时的后声腔，可以进一步提高喇叭在低音频段的音质，同时通过第三通孔31还可以加快喇叭线圈13的散热。
本申请的一个实施例中，结合图1所示，在前盖1的内壁紧邻华司11位置处设有连接环14，振膜12的外缘装配在连接环14上。该连接环14可以是金属材质也可以是非金属材质的圆环，例如钢环、塑料环、橡胶环等。其中，装配的方式例如可以是，先将连接环14通过打胶与华司11进行固定连接，然后再将振膜12的外缘通过打胶与连接环14连接，通过连接环14对振膜12进行固定。由于振膜12是一个对于磁场变化很敏感的元件，利用连接环14还能够对前盖1的振动起到缓冲作用，将振膜12的外缘借助连接环14固定到华司11上，相比于将振膜12的外缘直接固定到华司11上，可以减少 华司11的磁场对振膜12发声的干扰，保证喇叭的音质。
本申请的一个实施例中，结合图1所示，在环绕马达线圈7的外圈位置，盆架3内设有非金属环32，用于阻隔盆架3的导磁。通过非金属环32将盆架3分为两部分：一部分用于磁铁10的导磁，另一部分用于支撑马达线圈7。防止在马达和喇叭共同工作时，磁铁10产生的磁场和马达线圈7通电后产生的电磁场同时将盆架3磁化，造成磁场的叠加，从而造成喇叭的灵敏度降低，甚至造成喇叭的失真。
最后需要说明的是，可以通过线圈的绕线方式、接入的正负极以及电路的设计等方式，控制马达和喇叭的振动方向同步。在调节马达和喇叭的振动方向的同步时，通过向喇叭线圈输入直流电，当喇叭线圈和马达线圈同步向出音孔方向移动时，定义此时的喇叭线圈电流的输入端为正极。且当配重磁钢向出音孔方向移动时，定义此时的马达线圈电流的输入端为正极。然后对马达线圈和喇叭线圈的正极输入同相位的交流电信号，使得马达和喇叭的振动方向同步。
本申请实施例的电子产品，由于采用了上述的喇叭与马达的组合结构，能够节约电子产品的内部空间；且当电子产品中喇叭与马达共同工作时，控制二者振动方向同步，达到互相增强振动的效果。提高喇叭的音量的同时，还能增强马达的振感。且马达所在的第二腔室5扩充了喇叭工作时的后声腔体积，还能够进一步提高喇叭在低音频段的音质。
其中，电子产品可以是手表、手环、耳机等。
本说明书中各个实施例采用并列或者递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同或相似部分互相参见即可。
还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的 要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
