所述钢片本体315远离所述过渡部314的一侧向靠近所述上盖1方向弯折形成翻边316，所述翻边316与所述下壳本体33一体注塑成型。
所述下壳本体33对应所述挡墙17位置开设有避让缺口330，所述侧壁13包括自所述挡墙17远离所述发声单体5的一侧朝远离所述顶壁方向眼神的延伸壁131，所述延伸壁131远离所述顶壁11的一端延伸至所述缺口330并经所述缺口330暴露，所述延伸壁131相比所述挡墙17的高度大于所述平面部311的厚度，所述延伸壁131与所述平面部抵接并配合形成与所述沉槽313连通的密封槽，所述密封胶进一步填充至所述密封槽内。
所述发声单体5包括靠近所述上盖1的发声侧51以及与所述发声侧51相背的背侧52，所述发声侧51设有用于振动发声的振膜53，所述背侧52设有与所述振膜53相对的磁轭54，所述磁轭54穿过所述贯穿孔310露设于所述钢片31外，不需要额外占用所述后腔30的空间，同时由于所述钢片31的强度大，使得所述钢片31的厚度可以做小，进一步增加了所述后腔30的体积，提高所述扬声器箱100的声学性能。
更进一步的，所述磁轭54靠近所述钢片31的边缘至少部分朝所述上盖1方向凹陷形成有让位槽540，所述让位槽540与所述沉槽313连通，所述密封胶延伸至所述让位槽540内。
请参阅图6及图7，为保证所述沉槽313结构的成型，所述平面部311需要保证一定的直线长度；同时，考虑到所述钢片31成型模具的设计，所述钢片本体315也需要保证一定的直线长度，使得所述发声单体5的边缘与所述下壳本体33的间距d
1需要满足d
1≥1.4mm。
请参阅图6及图8，所述平面部311直接承载于所述挡墙17上，省去了钢片本体315的直线段及过渡部315的结构，使得所述发声单体5的边缘与所述下壳本体33之间的间距d
2可以缩减为0.2mm，大大减低了对安装距离的要求，同时使得所述钢片31的结构易于成型，并且节约了钢片31的制作材料，减少了成本。
可以理解的是，在本实施方式中，所述挡墙17仅仅设置于所述侧壁13的短边上，所述平面部311也仅有部分承载于所述挡墙17上，请参阅图9，在其他方式中，所述挡墙17还可以设置于所述侧壁13的长边上，所述平面部的整个外边缘均可以承载于所述挡墙17上，即所述第一侧边3111和第二侧边3312均承载于所述挡墙上，此时所述发声单体5边缘的任一位置与所述下壳本体33的间距均可以缩减为0.2mm，可以大幅缩小所述扬声器箱100的整体体积。
与相关技术相比，本申请提供的扬声器箱100中，所述钢片31贯穿开设有贯穿孔310。所述钢片31还包括环绕所述贯穿孔310的平面部311，所述上盖1包括挡墙17，所述平面部311承载于所述挡墙17上，所述平面部与所述下壳本体33配合围成环绕所述贯穿孔310的沉槽313,，所述沉槽313内填充密封胶，省去了相关技术中钢片本体315和过渡部315的结构，使所述发声单体5的边缘与所述上盖1的侧壁13的间距可以缩小，满足扬声器箱微小化的发展需求。
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。
