具体的，所述延伸部232包括由所述本体部231的周缘向远离所述振膜21方向弯折延伸并抵接于所述音圈22靠近所述振膜21一侧的第一延伸部2321和由所述第一延伸部2321的相对两侧沿所述音圈22的外周侧向远离所述振膜21方向弯折延伸的第二延伸部2322，所述第二延伸部2322贴合于所述音圈22的外周侧，该结构的设置进一步加强了骨架23与音圈22的固定强度，从而提高了所述发声器件100的可靠性。另外，所述第二延伸部2322可作为限位结构对所述音圈22进行限位，进而提高所述发声器件100的装配效率。

请参阅图4所示，图4为图3的另一种实施例的剖示图。在另一种实施例中提供一种发声器件，该实施方式与图3所示的实施方式区别在于，骨架结构不同。
所述骨架包括贴设固定于所述振动部211a靠近所述磁路系统3a一侧的本体部231a和由所述本体部231a的周缘向远离所述振膜21a方向弯折延伸的延伸部232a。所述本体部231a沿所述振膜21a的振动方向向所述振膜21a的正投影部分落入所述折环部212a范围内。该结构使得所述音圈22a的外径可以做大并超过所述振动部211a的内径，使得所述音圈22a的内侧可以设置更大的磁路，也就是说所述音圈22a的内侧可以设置尺寸更大的主磁钢33a，所述磁路系统3a的磁路可最大化，从而使得所述磁路系统3a的磁力线更强且驱动力更强，从而使得发声器件的声学性能优。
与相关技术相比，本实用新型的发声器件中，所述骨架包括贴设固定于所述振动部靠近所述磁路系统一侧的本体部和由所述本体部的周缘向远离所述振膜方向弯折延伸的延伸部，所述本体部呈平板状用以充当球顶结构，所述延伸部与所述音圈连接并将所述音圈悬置于所述磁间隙内。该结构的设置，使得该发声器件无需额外再设置一个的球顶来加强所述振膜的振动效果，而是直接将所述骨架的所述本体部用以充当球顶结构，节省了发声器件的内部空间，并且省略了相关技术中球顶分别与振膜和骨架连接的装配工序，进而提高了发声器件的装配效率，并降低了生产成本。另一方面，通过呈平板状的本体部充当球顶结构，增加了本体部与振动部的接触面积，进一步强加了所述振膜的固定效果，改善了所述发声器件的声学性能。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本实用新型的专利保护范围内。
