本发明的实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，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方式，都属于本申请保护的范围。
需要说明的是，当组件被称为“固定于”另一个组件，它可以直接在另一个组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中组件。
除非另有定义，本申请所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本申请中在说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本申请所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
现有的扬声器包括平面弹波、振膜和音圈，平面弹波适于连接振膜和音圈，并为振膜和音圈提供稳定的支撑。音圈在磁场中受到电流驱动而移动时，平面弹波确保振膜能够跟随音圈的运动而振动。音圈振动带动振膜振动，进而压缩空气产生声波。同时，平面弹波需为振膜提供必要的恢复力，使得平面弹波在扬声器的振膜在音圈在停止移动后能带动振膜迅速回到初始位置，平面弹波还能防止音圈在振动时与磁铁或其他部件接触。
一种实施方式中，扬声器还包括磁路系统，磁路系统包括磁铁、导磁板和场心柱，磁铁、导磁板和场心柱共同作用使得磁路系统的磁场分布均匀，使得音圈能够平稳的振动。
可选的，扬声器可为纸盆式、号筒式、球顶形等，不做限制。
现有的平面弹波一般使用单一的铜箔层来为整个扬声器提供导电性能和回复力，由于铜箔的回复力较低，因此使用该平面弹波制作的扬声器功率不能太大，大功率的扬声器会导致振幅增大，最终由于铜箔的沿展性和回复力的不足导致平面弹波断裂，造成扬声器机械损坏。因此现有的平面弹波只能适用于小功率扬声器，不适用于大功率扬声器。
可参考图1，本申请提供一种平面弹波100，包括导电层10和回复层20。回复层20设置于导电层10在第一方向上的一侧，回复层20适于在第一方向上提供回复力和在第二方向上限制平面弹波100的移动，第一方向与第二方向相交。
导电层10可为金属构件，具体的，导电层10可为铜、铜合金、银、铝合金等，不做限制。设置导电层10使平面弹波100具有电磁屏蔽的作用，有助于减少或消除电磁干扰对扬声器性能的影响，确保音频信号的纯净传输。此外，使用导电层10后无需设置锦丝线，从而极大的降低了扬声器的厚度，也避免了由于锦丝线断裂导致的扬声器失声，延长的产品的使用寿命，并优化了产品的生产工艺。
可选的，导电层10和回复层20在第一方向上的正投影相同。
具体的，在第二方向上限制平面弹波100的移动可为在第二方向上让平面弹波100不发生位移，也可为使平面弹波100在第二方向上发生的位移小。
本申请的平面弹波100通过设置层叠的导电层10和回复层20，且回复层20可在第一方向提供回复力，在第二方向上限制平面弹波100的移动，本申请的平面弹波100同时具备良好的导电性和回复力，回复层20使得平面弹波100不会由于在第一方向上沿展性和回复力的不足导致导电层10断裂，也可在第二方向上保持平面弹波100以及与平面弹波100连接的音圈在磁场中的位置稳定，避免出现声音失真、音质下降和额外的噪音，使平面弹波100能应用于大功率的扬声器。
一种实施方式中，回复层20为弹簧钢构件、玻璃纤维构件、碳纤维构件的任一者。
具体的，弹簧钢构件的主要组成材料为65Mn，65Mn的抗拉强度为a1，满足：a1≥980MPa，65Mn的屈服强度为b1，满足：b1≥740MPa。
具体的，碳纤维构件的主要组成材料可为一维碳纤维和/或二维碳纤维以及作为基体的树脂基材料，碳纤维的抗拉强度为a2，满足：a2≥1600MPa，碳纤维的屈服强度为b2，满足：b2≥1000MPa。
具体的，玻璃纤维的抗拉强度为a3，满足：a3≥1000MPa，玻璃纤维的屈服强度为b3，满足：b3≥1000MPa。
使用弹簧钢构件、玻璃纤维构件、碳纤维构件等具有良好的抗拉强度和屈服强度的材质作为回复层20，使得回复层20在第一方向上具有良好的回复力，使得平面弹波100在扬声器的振膜在音圈在停止移动后能带动振膜迅速回到初始位置，同时还可避免平面弹波100由于沿展性和回复力的不足出现断裂等现象。
可参考图1，一种实施方式中，回复层20在第一方向上的尺寸为d1，满足：130μm≤d1≤170μm。
可选的呢，d1可为130μm、140μm、150μm、160μm、170μm等，不做限制。
d1＜130μm时，回复层20的厚度过薄，回复层20的回复力不足以支撑回复层20带动平面弹波100的其余结构在第一方向上回复至初始位置；d1＞170μm时，回复层20的厚度已经能满足回复力要求，过厚的回复层20会导致材料的浪费；130μm≤d1≤170μm时，回复层20的厚度适中且能提供足够的回复力。
可选的，回复层20在第一方向上的尺寸可根据实际情况进行调整，大功率的扬声器的平面弹波100的回复层20的尺寸大于小功率(例如功率小于1瓦)的扬声器的平面弹波100的回复层20的尺寸，因为d1更大的回复层20能承受更大的振动。
可参考图1，一种实施方式中，导电层10在第一方向上的尺寸为d2，满足：10μm≤d2≤15μm。
可选的，d2可为10μm、11μm、12μm、13μm、14μm、15μm等，不做限制。
d2＜10μm时，导电层10的结构强度过低，可能在振动回复过程中，出现断裂等情况；d2＞15μm时，导电层10过厚，使得平面弹波100的整体重量和成本增高；10μm≤d2≤15μm时，既能保证导电层10的结构强度，也能降低平面弹波100的整体重量。
可参考图1，一种实施方式中，平面弹波100还包括第一绝缘层30，第一绝缘层30设置于导电层10和回复层20之间。
第一绝缘层30的材质可为塑料、橡胶等，具体的，塑料可为聚氯乙烯、聚乙烯、聚酰亚胺等，不做限制。
第一绝缘层30在第一方向上的尺寸为d3，满足：10μm≤d3≤15μm。可选的，d3可为10μm、11μm、12μm、13μm、14μm、15μm等，不做限制。
设置第一绝缘层30避免导电层10和回复层20之间电连通，导致扬声器功效受损。
可参考图1，一种实施方式中，平面弹波100还包括第一粘接层31和第二粘接层32，第一粘接层31设置于回复层20和第一绝缘层30之间，第二粘接层32设置于导电层10和第一绝缘层30之间。
可选的，第一粘接层31和第二粘接层32的材质可为树脂、橡胶、固化剂等，不做限制。具体的，第一绝缘层30的材质为聚酰亚胺，聚酰亚胺与第一粘接层31和第二粘接层32之间能形成部分交联结构，有利于提高第一绝缘层30与第一粘接层31和第二粘接层32的粘接强度，使平面弹拨的层结构之间不易发生整体的分离，提高平面弹波100的结构强度。
可选的，第一粘接层31和回复层20之间，和/或，第一粘接层31和第一绝缘层30之间，和/或，第二粘接层32和导电层10之间和/或，第二粘接层32和第一绝缘层30之间可能还设置有其余的结构层。
第一粘接层31在第一方向上的尺寸为d4，满足：20μm≤d4≤30μm。可选的，d4可为20μm、22μm、25μm、28μm、30μm等，不做限制。
第二粘接层32在第一方向上的尺寸为d5，满足：10μm≤d5≤15μm。可选的，d5可为10μm、11μm、12μm、13μm、14μm、15μm等，不做限制。
由于回复层20在第一方向上的尺寸大于导电层10的尺寸，第一粘接层31的尺寸需更大才能提供足够的粘接力，有利于提高平面弹波100的结构稳定性。
可参考图1，一种实施方式中，平面弹波100还包括第二绝缘层40，第二绝缘层40设置于回复层20远离导电层10的一侧。
