请参考图2、图5以及图7，本实施例中的所述底壁120和/或所述盖体200上开设有注入孔105，所述注入孔105与所述吸音腔103连通，所述吸音材料经所述注入孔105填充至所述吸音腔103内。
请参考图2，本实施例中的壳体还包括密封盖160，所述密封盖160盖设在所述注入孔105上。具体地，当通过所述注入孔105向所述吸音腔103内填充完成所述吸音材料后，用所述密封盖160将所述注入孔105密封封盖。
请参考图1以及图2，本实施例中的所述盖体200和/或所述底壁120还贯穿开设有与所述注入孔105间隔设置的泄漏孔106以及贴设于所述盖体200和/或所述底壁120并覆盖所述泄漏孔106的透气网布170，所述泄漏孔106与所述吸音腔103连通，所述泄漏孔106的孔径小于所述注入孔105的孔径。
请参考图3以及图4，本实施例中的所述发声单体300设有泄露部324，所述发声单体324依次经所述泄露部324、所述透气隔离件400以及所述吸音腔103与所述泄漏孔324连通，所述磁碗321与所述盆架312至少部分间隔形成所述泄露部324。
本实施例中的所述底壁120与所述挡墙140一体成型设置，优选为一体注塑成型，以简化生产装配。
本实施例中的所述吸音材料由沸石颗粒制成，当然还可以是由其它可改善声学性能的材料制成。
本实施例中的所述透气隔离件400为透气网布，所述透气隔离件400还可以是无纺布、尼龙编织网、羊毛编织网、金属网或纸张等。
本实施例中的扬声器模组不仅能够方便的进行生产装配，而且能够最大化的利用腔体101的空间用于填充吸音材料，从而能够很好的提高声学性能。且发声单体300上设置有支撑筋3211，而透气隔离件400抵压在支撑筋3211上，通过支撑筋3211对透气隔离件400的支撑，可以防止透气隔离件400因变形而贴在发声单体300的表面，进而可以防止因透气隔离件400的变形而影响扬声器模组的声学性能，并且透气隔离件400的装配也更便捷，本实施例中的扬声器模组的声学性能更加稳定。
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。
