 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。显然，所描述的实施方式仅是本申请的一部分实施方式，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它实施方式，都属于本申请保护的范围。
如图1所示，本申请提供的一种发声器件100，其包括盆架1、振动系统2以及磁路系统3。盆架1用于固定支撑振动系统2和磁路系统3。
如图2-5和9所示，振动系统2包括固定于盆架1的振膜21、驱动振膜21振动发声的音圈22以及固定于盆架1并与振膜21相对设置的弹性支撑组件23。其中，振膜21包括固定于盆架1的折环211、设置于折环211中央并靠近磁路系统3一侧的第一球顶212以及叠设于第一球顶上的第二球顶213。
所述磁路系统3具有磁间隙30，音圈22插设于磁间隙30内。
本实施方式中，第一球顶212包括球顶本体214，自球顶本体214靠近音圈22的一侧向音圈22延伸形成的第一壁215以及自第一壁215的末端弯折延伸形成的第二壁216。第二壁216通过第一壁215连接于音圈22，第二壁216与弹性支撑组件23连接且与音圈22间隔，第一壁215与音圈22的侧面相连接。进一步的，第一壁215和第二壁216分别包括两个且间隔设置于音圈22的相对两侧。每一第二壁216包括与音圈12间隔设置的第一段216a以及由第一段216a的相对两端分别向两个第一壁215延伸的第二段216b。其中，第一段216a与弹性支撑组件23连接，同一第二壁216的两个第二段216b分别与两个第一壁215连接，第一壁215和第二壁216用以将音圈22弹性悬挂于振膜21下方。
优选的，球顶本体214呈矩形结构，两个第一壁215和两个第二壁216分别位于球顶本体214的短轴两侧。另外，折环211为中空结构，其包括一横截面为弧形结构的突出部211a、自突出部211a向折环211内部水平延伸的第一边缘部211b以及自突出部211a向远离折环211水平延伸的第二边缘部211c；第二球顶213包括与第一球顶212胶合的中间部213a以及自中间部213a相对两侧向盆架1延伸的延伸部213b；第一边缘部211b叠设于延伸部213b上并与延伸部213b胶合。进一步的，延伸部213b正对间隔设置于第二壁216上方，优选的，延伸部213b与中间部213a为一体成型结构。第二球顶213的设置使得整个振膜21的强度增大并且双球顶的设置同时使得发声器件的高频特性也得到明显的改善。
优选的，球顶本体214与第一壁215和第二壁216可以是一体成型的结构，也可以是分体结构。例如，在本实施方式中，球顶本体214与第一壁215和第二壁216为一体成型结构，使得整个第一球顶212的成型更为可靠。进一步的，第一球顶212为镁铝合金、碳纤维、不锈钢或铝合金中的任意一种材料制成。当然，第一球顶212的材质并不限于此，只要是低密度、高硬度且易成型的材质均可作为制造第一球顶212的材料。第二球顶则为常规的铝箔、碳纤维、聚萘二甲酸乙二醇脂中的任意一种材料制成。
如图4-7所示，本实施方式中，弹性支撑组件23共同围成一中空区域231，音圈22远离第一球顶212的一端位于该中空区域231范围内。优选的，弹性支撑组件23包括两个且分别位于音圈22的相对两侧，两个弹性支撑组件23围成上述中空区域231。
具体的，每一弹性支撑组件23包括弹性件232以及贴设于弹性件232的辅助振膜233。第一段216a固定连接于弹性件232远离辅助振膜233的一侧。
弹性件232包括固定于盆架1的第一固定臂232a、分别支撑固定于同一第二壁216的两个第二段216b的两个第二固定臂232b以及由第一固定臂232a分别向两个第二固定臂232b延伸并形成固定连接的两个弹臂232c。两个第二固定臂232b与第一固定臂232a的固定连接可以为直接连接，也可以为间接连接。比如，在本实施方式中，每一第二固定臂232b与盆架1间隔设置并通过与其同侧的弹臂232c与第一固定臂232a形成直接连接；当然，两个第二固定臂232b分别固定于盆架1，每一第二固定臂232b通过与其同侧的弹臂232c与第一固定臂232a形成间接连接也是可行的。
辅助振膜233包括横截面呈弧形结构的第二折环233a，由第二折环233a的相对两侧分别延伸的第一连接部233b和第二连接部233c。第一连接部233b固定于第一固定臂232a，第二连接部233c固定于第二壁216的第一段216a。
弹性支撑组件23用于提高振动系统2振动的可靠性。本实施方式中，通过两个弹性支撑组件23的设置，形成了双弹性支撑组件的对称结构，使得对音圈22的支撑效果更稳定，更好的防止音圈22的横向摆动，提高振动系统2振动的可靠性，进而使得发声器件的可靠性很好。
优选的，弹性件 232为柔性线路板，音圈22 与弹性件232电连接，一方面可用于提供对音圈22 的支撑，另一方面为音圈22 引入外部电信号，避免了通过引线为音圈22 引入外部电信号时容易断线的问题，提高其可靠性。
上述结构中音圈 22 通过第一壁215与振膜21形成固定，该结构一方面通过第一壁215 实现对音圈22的横向摆动的有效抑制，提高发声器件100 的可靠性和稳定性；同时，第一壁215 固定胶合于音圈22 的侧面，该结构释放了音圈22 的结构设计，其位置可沿振膜21的振动方向上下浮动，音圈22高度不再受限于弹性支撑组件23，发声器件整体高度可以设计的更加轻薄。
在本实施方式中，以音圈22 呈圆角的矩形结构为例进行说明，四个第一壁215 分别位于音圈22 的四个圆角位置。使得第一球顶212更可靠地胶合于音圈22，更加有效地抑制了音圈22 的横向摆动，从而进一步提高振动系统2 振动的可靠性。此外，第一球顶212和叠设在其上的第二球顶213的双球顶结构的设置，使得整个振动系统强度增大的同时也有效的改善了发声器件100的高频特性。
另外，上述结构中，第一球顶212的两个第二壁216的设置。辅助振膜233与音圈22非直接连接，即辅助振膜233通过第二壁216与音圈22形成间接连接，使得辅助振膜233与音圈22之间形成一定的让位空间，该让位空间可以设置磁钢，从而释放了磁路系统3 的结构设计，弹性支撑组件23不直接与音圈22底部胶合，有效避开了磁路系统3与弹性支撑组件23的干涉，磁路系统3无需让位弹性支撑组件23，磁路系统可实现最大化结构，有效提高了所述发声器件100的声学性能。
值得一提的是，弹性支撑组件23与音圈22相互间隔设置或相互连接的。在本实施方式中，两个弹性支撑组件23分别与音圈22相连接，两个弹性件23的四个第二固定臂232b分别固定于音圈22的底面。第二固定臂232b为音圈22提供底部支撑，提高音圈22的振动可靠性，从而提高发声器件的可靠性。
如图8-10所示，磁路系统3包括磁轭31、固定于磁轭31的主磁钢32以及分别间隔设置于主磁钢32相对两侧并与主磁钢32形成磁间隙30的两个第一副磁钢34；每一第一副磁钢34位于与其同侧的第一段216a与音圈22 之间，即每一第一副磁钢34收容于与其同侧的弹性支撑组件23与音圈22形成的收容空间4内。此时，磁路系统3具有三个磁钢，实际应用中可以根据需求来优化设计，可以将磁路系统3设置为三磁钢磁路，亦可以进一步将磁路系统3优化为五磁钢磁路。
当磁路系统 3 为三磁钢磁路时，以音圈22呈圆角矩形结构为例说明，两个弹性支撑组件23位于音圈22的短轴的两侧，两个第一副磁钢34位于音圈22的短轴的两侧，且每一第一副磁钢34位于与其同侧的第一段216a 与音圈22之间，即每一第一副磁钢34收容于与其同侧的弹性支撑组件23 与音圈22形成的收容空间4内。此时，该三磁钢磁路结构使得磁路系统3的驱动性能更好，从而使得发声器件100的声学性能好。
当磁路系统3为五磁钢磁路时，比如，在本实施方式中，为了进一步有效利用空间，加强磁路系统3的体积，磁路系统3还包括分别间隔设置于主磁钢32另外相对两侧的两个第二副磁钢35；两个第二副磁钢35位于两个弹性支撑组件23之间。
进一步的，以音圈22呈圆角的矩形结构为例说明，两个弹性支撑组件23位于音圈22的短轴的两侧，两个第一副磁钢34位于音圈22的短轴的两侧，且每一第一副磁钢34位于与其同侧的第一段216a与音圈22之间，即每一第一副磁钢34收容于与其同侧的弹性支撑组件23与音圈22形成的收容空间4内，两个第二副磁钢35位于音圈22的长轴的两侧。此时，该五磁钢磁路结构的驱动性能更强，使得发声器件100的振动效果更优。
为了更进一步提高磁路系统3的性能，使磁路系统3的磁力线尽可能多的被音圈22切割，以形成更大的驱动力，磁路系统3还包括叠设于主磁钢32的主极芯36、分别叠设于两个第一副磁钢34的两个第一副极芯37以及嵌设于盆架1的上夹板38，上夹板38包括固定于盆架1的呈环状的固定环381和由固定环381分别向第二副磁钢35延伸的两个第二副极芯382，两个第二副极芯382分别叠设于两个第二副磁钢35。
综上，与相关技术相比，本申请的发声器件中，所述振膜包括固定于所述盆架的折环、设置于所述折环中央并靠近所述磁路系统一侧的第一球顶以及叠设于所述第一球顶上的第二球顶。所述第一球顶包括球顶本体、自所述球顶本体靠近所述音圈的一侧向所述音圈延伸形成的第一壁以及所述第一壁的末端弯折延伸形成的第二壁。所述第二壁通过所述第一壁连接于所述音圈，所述第二壁与所述弹性支撑组件连接且与所述音圈间隔，所述第一壁与所述音圈的侧面相连接，所述第一壁和所述第二壁用以将所述音圈弹性悬挂于所述振膜下方。
该结构中，所述音圈通过所述第一壁与所述振膜形成固定，该结构一方面实现对所述音圈振动时的横向摆动的抑制，提高其可靠性。
同时，所述第一壁固定胶合于所述音圈的侧面，该结构释放了所述音圈的结构设计，音圈高度不再受限于所述弹性支撑组件，发声器件整体高度可以设计的更加轻薄。
另外，通过所述球顶的两个所述第二壁的设置，所述辅助振膜与所述音圈非直接连接，即所述辅助振膜通过所述第二壁与所述音圈形成间接连接，使得所述辅助振膜与所述音圈之间形成一定的让位空间，该让位空间可以设置磁钢，消除了对磁路系统的设计的限制，磁路系统无需让位弹性支撑组件，磁路系统可实现最大化的多磁钢三磁路或五磁路结构，有效提高了所述发声器件的声学性能。
此外，在上述第一球顶之上设置了一层第一球顶，使得振动系统的整体强度得到增加的同时也使得发声器件的高频性能得到进一步的改善。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
