采用此种结构，磁碗31保持一周环绕音圈23，无需让位，性能最优化；利用所述第二段3132实现与所述盆架1的固定，固定面积大，可靠性好；同时所述第二段3132与所述盆架1的固定实现了所述磁路系统3的高度定位，使得所述磁路系统3与所述盆架1组装定位准确；即设置固定台阶3130与所述盆架1固定，不易于发生所述盆架1与所述磁碗31移动，有效保证了所述盆架1与所述磁碗31的固定的稳定度；节省了磁路系统3的内部空间，同时还保证预留了充足振动系统2的振动空间；避免了结构干涉，从而提高了所述发声器件100的可靠性。
优选的，所述第一段3131与所述第二段3132均沿垂直于所述振膜21的振动方向延伸形成；所述第二段3132靠近所述盆架1的一侧与所述盆架1的接触部分通过激光点焊固定，可靠性更好，更加稳定，同时第二段3132与盆架1焊接厚度大，不易击穿，防止激光损伤振膜21等结构；同时盆架1与振膜21的间距大，其振动空间更大。
即所述翻边313包括两个，所述第二段3132包括两个；所述缺口12与所述第二段3132一一对应，所述第二段3132收容于所述缺口12并固定于所述缺口12；即所述第二段3132固定于所述第二底壁112，使得整个发声器件100沿振膜21的振动方向上的高度减小。即通过此设置，使得发声器件100的结构布局更加合理，例如所述第二段3132收容于缺口12，所述弹性导电件24固定于盆架1的短轴边1a，空间利用率更高。
与相关技术相比，本实用新型的发声器件，所述磁碗包括磁碗底壁、由所述磁碗底壁的周缘向靠近所述振膜方向弯折延伸的呈环状的磁碗侧壁以及由所述磁碗侧壁靠近所述振膜的一端向靠近所述盆架方向弯折延伸的翻边，所述磁钢组件固定于所述磁碗底壁并与所述磁碗侧壁间隔形成所述磁间隙；所述翻边包括由所述磁碗侧壁靠近所述振膜的一端向靠近所述盆架方向弯折延伸的第一段以及自所述第一段远离所述磁碗侧壁的一端向靠近所述盆架方向延伸的第二段，所述第一段靠近所述振膜的一侧与所述振膜的间距小于所述第二段靠近所述振膜的一侧与所述振膜的间距；所述第一段靠近所述第二段的一侧与所述第二段围成固定台阶，所述第二段固定于所述盆架；采用此种结构，磁碗保持一周环绕音圈，无需让位，性能最优化；利用所述第二段实现与所述盆架的固定，固定面积大，可靠性好；同时所述第二段与所述盆架的固定实现了所述磁路系统的高度定位，使得所述磁路系统与所述盆架组装定位准确；即设置固定台阶与所述盆架固定，不易于发生所述盆架与所述磁碗移动，有效保证了所述盆架与所述磁碗的固定的稳定度；节省了磁路系统的内部空间，同时还保证预留了充足振动系统的振动空间；避免了结构干涉，从而提高了所述发声器件的可靠性。
