本实施方式中，所述上盖2还设有由其外侧凸出延伸的托壁25，所述第三段73贴设于所述托壁25，从而对第三段73形成支撑，方便与外部电信号源连接。
更优的，所述托壁25靠近所述第三段73的一侧设有定位柱251，所述第三段73设有贯穿其上的定位孔731，所述定位柱251插设于所述定位孔731内，形成对所述第三段73的定位，一方面提高装配效率，另一方面避免了第三段73的移动，提高其与外部电源信号连接的稳定性。
进一步，所述扬声器箱100还包括叠设固定于所述发声单体3靠近所述主体部41一侧的支撑件8，所述主体部41抵接于所述支撑件8。支撑件8形成了对所述主体部41的支撑，使得透气隔离件4的结构稳定，提升了在所述后腔102内填充吸音颗粒5的填充效果，进一步改善声学性能。
本实施方式中，所述支撑件8贴合于所述磁路系统32靠近所述主体部41的一侧。
具体的，所述支撑件8包括间隔相对设置的两个第一支撑部81和连接两个第一支撑部81的第二支撑部82，从而形成“工”字型结构，支撑效果更好。比如，第一支撑部81平行于发声单体3的长轴间隔正对设置，第二支撑部82平行于发声单体3的短轴设置。
所述扬声器箱100还设有灌粉孔9以及盖设所述灌粉孔9的密封盖91，所述灌粉孔9与后腔102连通，用于向后腔102内填充吸音颗粒5。
如图2所示，所述灌粉孔9包括至少两个，且分别设置于所述上盖2和所述下盖1。
当然，所述灌粉孔9的设置不限于上述方式，还可以单独设置，即只设置于上盖2或只设置于下盖1上。
与相关技术相比，本实用新型的扬声器箱将所述发声单体支撑固定于所述支撑壁且使透气隔离件位于发声单体与下盖之间，二者共同将所述收容空间分隔成前腔和后腔，所述透气隔离件包括盖设于所述发声单体并与所述下盖间隔设置的主体部和由所述主体部的周缘向所述支撑壁弯折延伸的延伸壁，所述延伸壁环绕所述发声单体的周侧设置，所述上盖包括由所述支撑壁的外周缘向所述下盖方向凸出延伸的固定壁，所述延伸壁与所述固定壁胶合固定，上述结构则使得透气隔离件远离所述发声单体一侧的后腔可全部填充吸音颗粒作为虚拟声腔，极大程度提高后腔的吸音颗粒的灌装效率，有效提高了扬声器箱的低频声学性能，同时，因透气隔离件通过固定壁胶合形成固定，所述固定壁还作为定位部以实现快速定位及胶合，有效提高了生产效率。
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。
