请一并参阅图3与图4，所述圈铁支架20的周缘与形成腔体的壳体10内侧嵌合，所述圈铁支架20包括动铁支撑部21和动圈支撑部22，所述动圈支撑部22呈环形，所述动铁支撑部21设于所述动圈支撑部22的一侧；具体的，本发明实施例中，动圈支撑部22和动铁支撑部21呈上下关系设置，动铁支撑部21设于靠近壳体10音管12的一侧，动圈支撑部22设置在动铁支撑部21的下方。所述动圈支撑部22的环形内壁上设有朝向所述动铁支撑部21的凸舌221，所述凸舌221上设有一第一固定槽2211，所述动铁支撑部21呈拱形，包括位中部的固定部211以及位于两端的连接臂212。所述连接臂212的末端与所述圈支撑部22连接，具体的，所述连接臂212的末端的连线长度小于所述动圈支撑部22的内径。所述固定部211的中部朝向所述第一固定槽2211设有第二固定槽2111。
进一步的，请参阅图5与图6，所述第一固定槽2211包括第一底托2212和与所述第一底托2212垂直设置的第一夹持壁2213，所述第一夹持壁2213与所述第一底托2212围合形成第一L型支撑结构；所述第二固定槽2111由所述固定部211向内凹陷形成，包括与所述第一底托2212平行设置的第二底托2112以及与所述第二底托2112垂直设置的第二夹持壁2113，所述第二夹持壁2113与所述第二底托2112围合形成与所述第一固定槽对立的第二L型支撑结构。装 配时，所述动铁组件30的底部受所述第一底托2212和所述第二底托2112所支撑，所述动铁组件30的侧面部分受第一夹持壁2213和所述第二夹持壁2113限位。使得动铁组件30部分容置于圈铁支架20的上端。使得扬声模块的内部发声单元组装工序简单，组装稳定效果好。
进一步的，本发明实施例中，所述第一底托2212由所述凸舌221向外延伸形成。通过延伸的第一底托2212加强了对于动铁组件300的支撑性的同时，也优化了对于音膜41出音的避让空间。同时，所述动铁支撑部21的中部呈镂空型，使得所述凸舌221与所述动铁支撑部21围合形成一漏孔222。音膜41震动发出的音频可通过两个漏孔222向外传输，使得音膜41发出的音频受动铁支撑部21结构的遮蔽效果降低。从而让音膜41发出的音频传输效果更加理想。此外，动铁支撑部21通过靠向壳体10内壁呈拱形型结构设计也极大的提升了壳体内的空腔容积，使得音频输出效果更佳。
本发明实施例中，所述第一夹持壁2213和所述第二夹持壁2113与所述出音孔122的朝向对齐。进而使得所述动铁组件30装配后对向出音孔122。进而让动铁组件的出音朝向直接对向出音孔122。优化了出音效果。
进一步的，所述动铁组件300为柱体状。所述动铁组件30设于所述动铁支撑部21上，具体的，容置于所述第一固定槽2211和所述第二固定槽二固定槽2111之间。
进一步的，所述动圈组件40包括层叠设置的音膜41、音圈42、华司43、磁铁44，所述音膜41的周缘卡接固定于所述动圈支撑部22的内侧，所述音42圈、所述华司43、所述磁铁44与所述音膜41同轴设置；所述动圈组件40还包括U型杯45和动圈支架46，所述动圈支架46的上表面与所述音膜41的下端面的外缘贴合，所述U型杯45用于封堵所述动圈支架46的内环使所述动圈组件40的下端封闭。
本发明实施例中，在实际生产装配过程中，通过将动铁组件30***圈铁支架20内实现装配，动圈组件40依次层叠组装，并与圈铁支架20扣合组装，使得扬声模块的内部发声单元组装工序简单，组装稳定效果好。同时，动铁组件30以及动圈组件400的发声区域位于音膜41，圈铁支架20以及壳体10围合形 成的音腔内，利用动铁组件30能实现中高音段的清脆音质，利用动圈组件40能实现低音段的沉稳音质。两者发出的声音在音腔内形成共鸣，优化了输出的音质效果。
请参阅图7，为本发明实施例提出的扬声模块的壳体10内侧结构示意图。如图所示，所述壳体10的内壁设有容置拾音麦克风50的装配槽13，所述装配槽13仿形于所述拾音麦克风50，本发明实施例中，拾音麦克风50为长方体型，对应的，装配槽13仿形于拾音麦克风11也呈长方体的沉槽状。以使得所述拾音麦克风11嵌合与所述装配槽13内。
进一步的，请参阅图8，为本发明实施例提出的扬声模块的动圈支架46与U型杯45的结构示意图。其中，所述动圈支架46的内环设有三个向内延伸的凸起461，所述U型杯9的侧壁设有与所述凸起461配型的卡槽451。上述U型杯45用于封装动圈组件40，在动圈支架46装配后，实现了对于动圈组件40的初步封装，再通过上述U型杯45的卡槽451与动圈支架46的凸起461对位匹配后完成动圈组件40的封装。采用上述对位方式简化了整装过程。可以理解的，本发明实施例中采用三个凸起461结构对三个卡槽451结构对位匹配仅仅为一种较佳的实施方式，在本发明的其他实施例中，凸起461和卡槽451的设置个数还可以是其他设定数量。本发明对此不作具体限定。
此外，上述动圈支架46在面向所述圈铁支架20的一侧设有沉槽462，所述圈铁支架20的所述动圈支撑部22部分容置于所述沉槽462内。通过上述沉槽462用以实现与圈铁支架20的扣合装配。进一步的提升了装配稳固性。
进一步的，请参阅图9与图10，本发明实施例中，动圈支架46上设有两个透音孔463，所述动圈支架46被所述透音孔463轴向穿透，进而使得所述壳体10的腔体可通过透音孔463导通至位于动圈支架46下端的空间内(可以理解的，图示壳体10仅仅为形成扬声模块的上壳体，另一半的下壳体在图中并未示出，动圈支架46位于上壳体与下壳体的连接处，且外缘与上壳体内壁完全贴合，内部空气流通通过上述透音孔463实现)。具体的，上述透音孔463为弧形的弯孔，所述透音孔463沿所述动圈支架46的边缘弧形扩散形成。通过设置的透音孔463使得音膜41发出的音频还可以穿过动圈支架46传达到扬声模块下壳体 的腔体内。使得最终通过出音孔输出的音频更加绵长，音质效果进一步得到提升。
示例而非限定的，本发明实施例中，透音孔463仿形于动圈支架呈弧形设计，其具体用途为透音效果，在本发明的其他实施例中，对透音孔463的形状不做具体限定，同时，透音孔463设置为两个也是本发明的一种较佳实施方式，本发明对此亦不做具体限定。
综上，本发明上述实施例中的扬声模块，相比于现有技术，本发明扬声模块在实际生产装配过程中，通过将动铁组件30***圈铁支架20内实现装配，动圈组件40依次层叠组装，并与圈铁支架20扣合组装，使得扬声模块的内部发声单元组装工序简单；且通过圈铁支架20将动铁组件30和动圈组件40一体化装配，使得组装稳定效果更好。同时，动铁组件30以及动圈组件40的发声区域位于音膜41，圈铁支架20以及壳体10围合形成的腔体内，利用动铁组件30能实现中高音段的清脆音质，利用动圈组件40能实现低音段的沉稳音质。两者发出的声音在腔体内形成共鸣，优化了输出的音质效果；此外，动铁支撑部21通过靠向壳体10内壁呈拱形结构设计也极大的提升了壳体内的空腔容积，使得音频输出效果更佳；动铁组件30朝向向出音孔101方向，使得动铁组件30在输出的声音能直接通过腔体不受阻挡的传输至出音孔101。出音效果更好；通过U型杯45的卡槽451与动圈支架46的凸起461对位匹配后完成动圈组件40的封装，简化了整装过程。
此外，本发明还提出一种耳机，包括至少一上述的扬声模块。耳机可以为有线耳机或无线耳机等形式，或是入耳式耳机或外戴式耳机等形式，亦或是具备耳机形态的助听器等医疗设备，在此不做限定。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
