值得一提的是，所述磁碗31呈矩形结构，所述磁碗31的四个角的位置凹陷形成四个所述缺口3101，所述支撑脚12包括四个且分别插设于四个所述缺口3101内，所述第五臂52包括四个且分别设置于所述磁碗31的四个角的位置，四个所述第五臂52分别固定于四个所述支撑脚12远离所述盆架本体11的一端，通过支撑脚12的设置，使得所述第五臂52的装配可靠性更高。当然，磁碗呈其他的结构形式也是可行的，其可以根据实际情况进行具体的设置。
更优的，所述磁碗31靠近所述振膜21的一侧凹陷形成收容槽310，所述导电件5固定收容于所述收容槽310内，所述连接臂422收容于所述收容槽310内且夹设固定于所述主磁钢32和所述导电件5之间，进一步地提高所述导电件5和所述连接臂422固定的可靠性。
与相关技术相比，本实用新型的发声器件中，弹性导电件，所述弹性导电件包括固定于所述振膜朝向所述磁路系统一侧且与所述音圈电连接的固定臂以及由所述固定臂沿所述振膜的振动方向朝向所述磁路系统延伸的弹性臂，所述弹性臂沿所述振动方向产生弹性形变；所述主磁钢沿所述振动方向设有贯穿其上的通孔，所述弹性臂穿过所述通孔与外部电路电连接；上述结构中，所述弹性导电件的弹性臂沿所述振动方向延伸，避免了在振动过程中弹性臂因受到垂直的驱动力而损坏的问题，有效地提高了所述弹性导电件的使用寿命，提高了所述振动系统的可靠性，以保证所述发声器件的可靠性高。
