请参考图1至图7，本实施例中的所述底壁110靠近所述顶壁120的一侧朝所述顶壁120方向凸设有挡墙140，所述透气隔离件300注塑在所述挡墙140靠近所述底壁110的一端并将所述收容空间分割成收容所述发声组件200的容纳腔101以及收容吸音材料的吸音腔102，所述透气隔离件300、所述挡墙140及所述底壁110围合形成所述容纳腔101，所述吸音腔102位于所述透气隔离件300与所述顶壁120之间，具体地，所述吸音腔102由所述透气隔离件300、所述挡墙140、所述底壁110以及所述顶壁120围合形成。由于收容空间内除容纳腔101外的所有区域均能够填充吸音材料，从而使收容空间内具有大量的空间可用于填充吸音材料，提高了扬声器模组的声学性能。
一些相关技术中，透气隔离件300往往放置在发声组件200的侧方，进而使放置发声组件200的容纳腔101占据很大的空间，致使吸音腔102太小，声学性能未能显著改善，另外，在一些相关技术中，透气隔离件300并非组成容纳腔101的一部分，从而使透气隔离件300与容纳腔101之间的部分空间不能充分利用，致使吸音腔102太小，声学性能未能显著改善。为解决上述问题，本实施例中的所述透气隔离件300位于所述发声组件200背离振膜211的一侧，而且所述透气隔离件300为组成所述容纳腔101的一部分，进而能够很好的利用所述顶壁120与所述透气隔离件300之间的空间以放置所述吸音材料。
优选地，所述容纳腔101的形状与所述发声组件200相适配，可以减小放置所述发声组件200的空间，从而可以留出更多的空间用于放置所述吸音材料，以使本实施例中的扬声器模组的低频声学性能更佳。
优选地，所述底壁110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。
请参考图2以及图3，本实施例中的所述发声组件200包括发声单体210以及收容并固定所述发声单体210的支架220，所述发声单体210具有背离所述顶壁120的振膜211，所述底壁110贯穿开设有安装孔111，所述支架220经所述安装孔111固定于所述壳体100并将所述发声单体210固定于所述底壁110与所述透气隔离件300之间。由于所述透气隔离件300与所述挡墙140一体成型设置，所以在装配时，可以省去将所述透气隔离件300胶合或焊接在所述挡墙140上的步骤，而且由于透气隔离件300为软性材料制成，故而将所述透气隔离件300胶合或焊接在所述支撑环上的步骤较为费时费力，因此，本实施例的扬声器模组在装配时，只需要将发声单体210安装在支架220上，然后将支架220经安装孔111固定在壳体100上，即完成装配，或者，首先将所述发声单体210经所述安装口安装在所述容纳腔101内，然后支架220经安装孔111固定在壳体100上，本实施例中的扬声器模组装配步骤简化，装配更为简单方便。
请参考图3，本实施例中的所述支架220包括与所述安装孔111适配并与所述透气隔离件300相对且间隔设置的安装部221、以及自所述安装部221朝所述透气隔离件300方向弯折延伸的支撑壁222，所述支撑壁222围设在所述发声单体210外周并与所述发声单体210固定，所述振膜211与所述安装部221相对且间隔设置形成前声腔103，所述发声单体210远离所述支撑壁222的一侧与所述透气隔离件300抵接。由于所述安装部221与所述安装孔111的大小适配，能够将所述安装孔111密封。
请参考图4以及图5，本实施例中的所述挡墙140靠近所述发声单体210的一侧对应朝远离所述发声单体210的方向凹陷形成与所述支撑壁222适配的避让部141，所述支撑壁222安装在所述避让部141并与所述挡墙140配合固定。通过将所述支撑壁222安装在所述避让部141，能够保证支架220安装的稳定性，可以防止支架220掉出。
在某些实施例中，所述支架220经所述安装孔111与所述壳体100胶合固定或超声焊接固定，具体地，所述安装部221与所述安装孔111的内侧壁130胶合固定或超声焊接固定，或所述支撑壁222与所述挡墙140胶合固定或超声焊接固定。
在某些实施例中，所述支架220仅具有安装部221，用于封盖所述安装孔111，装配时，首先将所述发声单体210经所述安装孔111安装在容纳腔101内，然后通过安装部221封盖所述安装孔111。
请参考图3，本实施例中的所述挡墙140高出所述发声单体210的与所述振膜211相反的表面，进而使所述透气隔离件300与所述发声单体210之间留有间隙，进而，所述发声单体210与所述透气隔离件300之间能够使空气充分流通，更利于声音的传播，能够提高本实施例中的扬声器模组的声学性能。
请参考图3，请参考图3，本实施例中的所述透气隔离件300与所述顶壁120之间存在间隙，进而能够保证所述容纳腔101与所述吸音腔102的空气流通的顺畅性能，从而提高了本实施例中的扬声器模组的可靠性能和低频声学性能。
请参考图3-图5，本实施例中的扬声器模组包括依次贯穿所述侧壁130、所述挡墙140及所述支撑壁222的出音通道400，所述出音通道400远离所述发声单体210的一端与外界连通，所述出音通道400靠近所述发声单体210的一端与所述前声腔103连通。
请参考图1-图3，本实施例中的所述扬声器模组还包括贴设于所述侧壁130并覆盖在所述出音通道400远离所述发声单体210一端的防尘透气网布410。
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300为透气网布，所述透气隔离件300还可以是无纺布、尼龙编织网、羊毛编织网、金属网或纸张等。
请参考图4以及图5，本实施例中的所述底壁110和/或所述顶壁120上开设有注入孔104，所述注入孔104与所述吸音腔102连通，所述吸音材料经所述注入孔104填充至所述吸音腔102内。
请参考图2，本实施例中的壳体100还包括密封盖150，所述密封盖150盖设在所述注入孔104上。具体地，当通过所述注入孔104向所述吸音腔102内填充完成所述吸音材料后，用所述密封盖150将所述注入孔104密封。
请参考图2、图4以及图5，本实施例中的所述顶壁120和/或所述底壁110还贯穿开设有与所述注入孔104间隔设置的泄漏孔105，通过所述泄漏孔105能够平衡所述吸音腔102的内外声压，所述扬声器模组还包括贴设于所述顶壁120和/或所述底壁110并覆盖所述泄漏孔105的透气网布160，所述泄漏孔105的孔径小于所述注入孔104的孔径。
优选地，所述泄漏孔105贯穿开设在所述顶壁120上，所述注入孔104贯穿开设在所述底壁110上。
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的空间用于填充吸音材料，从而能够很好的提高声学性能。
