参见图1至3，本发明提供了一种扬声器，包括：振动系统40以及与振动系统40配合在一起的磁路系统60；
振动系统40包括振膜41以及结合于振膜上的音圈；振膜41的前侧与前音腔盖20之间的空间形成前音腔，振膜41的背侧与后音腔盖30之间的空间形成后音腔。
其中，还包括多个沿振膜41的振动方向设置的注塑嵌件50，注塑嵌件50包括相对设置的第一端和第二端，第一端与前音腔盖20的靠近振膜41的一面相接合，第二端与后音腔盖30的靠近振膜41的一面相接合。
扬声器包括收容振动系统40和磁路系统60的外壳10以及与外壳10组配在一起的前盖；前音腔盖20为扬声器的前盖；外壳10的底面开口，磁路系统60包括导磁轭，导磁轭装配在所述外壳10的底面开口处，作为所述后音腔盖30。
注塑嵌件50的第一端为前音腔支撑面51、第二端为后音腔支撑面52，还包括设置于第一端和第二端之间的振膜连接面53，振膜41连接固定在振膜连接面上53。
本发明实施例的一个技术效果在于，在外壳10内设置多个注塑嵌件50，通过注塑嵌件50的前音腔支撑面51、后音腔支撑面52及振膜连接面53连接前音腔盖20、后音腔盖30以及收容于所述外壳10内的振动系统40。注塑嵌件50不会在注塑成型后出现翘曲变形的情况，能够保证外壳10的振膜连接面53相对于前音腔支撑面51及后音腔支撑面52的相对距离及 平行度的稳定性，从而确保扬声器的声学性能的稳定。
下面对本发明实施例提供的扬声器做进一步的具体介绍。
本发明实施例中，注塑嵌件50为刚性注塑嵌件。刚性注塑嵌件可通过金属材料支撑，金属材料支撑的刚性注塑嵌件，相对于现有技术中的塑胶托台，在加工制作时的精度较高，平面度误差较小，并且在外壳10注塑成型后不会发生翘曲变形以及外壳10外观缩水的情况，可有效保证外壳10的振膜连接面53相对于前音腔支撑面51及后音腔支撑面52的相对距离及平行度的稳定性。
本发明实施例中提供的注塑件的实现方式包括多种，一种可实现的方式是，参见图4，可选地，注塑嵌件50包括嵌件主体54及支撑板55，嵌件主体包括第一嵌体541和第二嵌体542。其中，嵌件主体54相对的两端为前音腔支撑面51及后音腔支撑面52，前音腔支撑面51及后音腔支撑面52均与嵌件主体54的轴线垂直。也就是说前音腔支撑面51与后音腔支撑面52相互平行。
可选地，嵌件主体54为一体结构。支撑板55环绕嵌件主体54的外周一圈与嵌件主体54的外侧壁连接，支撑板55朝向前音腔支撑面51的表面为振膜连接面53，振膜连接面53与前音腔支撑面51平行。也就是说前音腔支撑面51、后音腔支撑面52及振膜连接面53均相互平行。振膜连接面53与振膜41之间可通过粘贴层进行连接。
进一步地，为保证扬声器不会发生偏振的情况，外壳10内的多个注塑嵌件50的前音腔支撑面51处于同一平面内，进而多个后音腔支撑面52处于同一个平面内，多个振膜连接面53处于同一个平面内。前音腔盖20、后音腔盖30以及振膜41的相对距离稳定且相同，进而保证扬声器不会出现偏振的情况，保证了扬声器的声学性能。
注塑嵌件50的另一种可实现的方式是，继续参见图4，可选地，嵌件主体54为分体结构。嵌件主体54包括第一嵌体541及第二嵌体542。此种方式与上一种方式的区别在于嵌件主体54为分体结构。其中，第一嵌体541的一端与支撑板55连接，另一端为前音腔支撑面51。第二嵌体542的一端与支撑板55连接，另一端为前音腔支撑面51。前音腔支撑面51及后 音腔支撑面52均与嵌件主体54的轴线垂直，振膜连接面53与前音腔支撑面51平行。
继续参见图4，为了增强外壳10与注塑嵌件50之间的连接面积，本发明实施例中，可选地，嵌件主体54上设置有粗糙结构56。通过粗糙结构56增强了外壳10与注塑嵌件50之间的连接面积，使得两者之间的接合更加牢固，而且增强了外壳10的气密性，降低了潜在的气密性风险。粗糙结构56的设置位置可根据不同的连接强度需求，粗糙结构56位于粗糙结构位于第一嵌体541和/或第二嵌体542。图4中所示的粗糙结构56位于第二嵌体542。
本发明实施例中，粗糙结构56的实现方式包括多种，可选地，粗糙结构56包括螺旋结构、连续凸凹结构及不规则花纹。当然还包括其他形式的粗糙结构56，此处不做一一介绍。
本发明实施例中，一种外壳10的实现方案是，外壳10是通过预埋注塑嵌件50后，再通过注塑成型得到的。举例来说，在注塑之前，将注塑嵌件50预先设置在外壳10的四个角位置处，采用注塑工艺得到外壳10。此时的外壳10内具有四个注塑嵌件50。
外壳10可根据不同的需求设计为不同的形状，例如矩形、圆形等等。根据外壳10的不同形状，注塑嵌件50的设置位置也不同，例如，如图5所示，外壳10为矩形结构，注塑嵌件50为四个，并分别设置在外壳10的四个角。外壳10为矩形结构，注塑嵌件50为多个时，多个注塑嵌件50可沿着外壳10的长度方向的对称轴和/或宽度方向的对称轴对称设置。再例如，外壳10也为圆形结构，注塑嵌件50为多个，均布设置在外壳10的内侧壁上。
本发明实施例中，根据不同形式的扬声器，前音腔盖20实现方式不同，例如，扬声器为侧发声形式，扬声器的出声口设置在外壳10的侧壁上，前音腔盖20可为钢片，以阻挡声音从上方传出。
进一步地，本发明实施例还提供了一种扬声器模组，包括：模组壳体及如上述中所述的扬声器；
扬声器设置在所述模组壳体中，模组壳体具有出声口，扬声器所发出 的声音可从出声口传出。
虽然已经通过示例对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
