请参图1-6所示，本实用新型提供一种发声器件100，包括盆架1、分别固定于盆架1的振动系统2和磁路系统3，所述磁路系统3具有磁间隙30，所述磁路系统3用于驱动所述振动系统2振动发声。
本实施方式中，所述盆架1呈矩形。
所述振动系统2包括振膜21、音圈22、骨架23、球顶24以及弹性支撑组件25。
所述振膜21固定于所述盆架1。所述振膜21包括振动部213、由所述振动部213的周缘弯折延伸的折环部212、由所述折环部212远离所述振动部213的一侧弯折延伸的固定部211以及贯穿所述振动部的通孔210。所述固定部211固定于所述盆架1。
所述音圈22固定于所述振膜21并插设于所述磁间隙30以驱动所述振膜21振动发声。
所述音圈22为音圈线绕制。
所述骨架23将所述音圈22连接至所述振膜21。
具体的，所述骨架23包括骨架本体231、骨架连接臂232以及骨架侧壁233。
所述骨架本体231固定于所述振膜21靠近所述磁路系统3一侧。所述骨架本体231用于将所述振膜21和所述音圈22连接，以实现所述音圈22驱动所述振膜21振动发声。
具体的，所述骨架本体231包括贴合于所述振动部213的呈环形的主体部2311。
所述主体部2311与所述骨架侧壁232连接。所述主体部2311呈环形。所述主体部2311固定于所述振动部213。具体的，所述主体部2311固定于所述振膜21靠近所述磁路系统3的一侧。
所述主体部2311用于固定所述球顶24。

所述骨架连接臂232由所述骨架本体231向所述磁路系统3的方向延伸并与所述音圈22连接。具体的，所述骨架连接臂232由所述骨架本体231的内周缘向所述音圈22的方向弯折延伸形成。所述骨架连接臂232用于将所述音圈22固定，并使得所述音圈22可以较好插入到所述磁间隙30内，从而保证所述磁路系统3与所述骨架23和所述球顶24的间隔而不相互接触，从而提高所述发声器件100的可靠性。
更优的，所述骨架连接臂232由所述音圈22靠近所述振膜21的一端部分插入所述音圈22内并与所述音圈22形成一体，以将所述音圈22悬浮于所述磁间隙30内。本实施方式中，所述音圈线部分绕设于所述骨架连接臂232。沿所述振膜21的振动方向所述音圈22绕设于所述骨架连接臂232部分的高度小于所述音圈22的高度。也就是说，该结构中至少部分所述骨架连接臂232外露于所述音圈22。具体的，所述骨架连接臂232包括由所述骨架本体231沿所述振动方向延伸的第一段2321和由所述第一段2321远离所述骨架本体231的一端沿所述振动方向延伸的第二段2322。所述音圈线部分绕设于所述第二段2322。该结构相对于相关技术的方案来说取消了胶合工艺，从而使得避免溢胶的风险，提高了发声器件100的可靠性，同时该结构也避免胶合面平整度和胶的厚度影响，并使得发声器件100的振动空间和磁间隙30不受影响，从而使得发声器件100的声学性能好。
本实施方式中，所述骨架连接臂232沿所述振膜21的振动方向向所述音圈22的正投影完全落入所述音圈22内。该结构确保了所述骨架连接臂232在垂直于所述振膜21的振动方向的平面内不外露出所述音圈22，从而使得所述骨架连接臂232不干扰和不影响发声器件100的振动空间，从而使得发声器件100的声学性能好。
所述骨架侧壁232由所述骨架本体231的外周缘的相对两侧分别向所述磁路系统3的方向延伸。所述骨架侧壁232包括两个，两个所述骨架侧壁232分别间隔设置于所述音圈22的相对两侧。所述骨架侧壁232用于连接所述弹性支撑组件25。

所述第一弹性件2511为柔性线路板。所述第二延伸壁2511b与所述音圈22的引线电连接。所述第一弹性件2511结构一方面用于提高所述振动系统2的振动强度和平衡，抑制摇摆，另一方向为所述音圈22引出至连接外部电源，避免了音圈引线结构引出电源时音圈引线容易断裂的风险。
本实施方式中，所述主体部2311远离所述振膜21的一侧设有向远离所述磁路系统3的方向凹陷形成收容槽23110。所述第二延伸壁2511b收容于所述收容槽23110内。该结构利用所述收容槽23110形成的空间，该空间将所述第二延伸壁2511b收容固定，从而减少所述第二延伸壁2511b对所述发声器件100内部的振动空间的占用，保证了所述发声器件100内部的振动空间不受影响，从而使得发声器件100的声学性能好。
更优的，所述收容槽23110除了用于所述第二延伸壁2511b形成让位，所述收容槽23110还可以用于定位。具体的，所述收容槽23110突出于所述主体部2311靠近所述振膜21的一侧，所述球顶24对应所述收容槽23110的位置设有避让口240，所述收容槽23110卡设于所述避让口240并与所述球顶24平齐。该结构提高所述球顶24的安装效率，并实现对所述球顶24的定位，提高所述发声器件100的安装效率和可靠性。
