目前的一些扬声器中，为了F0(谐振频率)，提升低频频响，从而将后腔体积设计最大化，而后腔对应的后腔壳部的厚度也越来越小。但这样的设计带来的问题便是，后腔壳部容易在振膜的振动过程中发生谐振，出现失真，从而影响声学性能。
基于上述问题，本实用新型提出一种扬声器模组。
在本实用新型的一实施例中，如图1至图4所示，所述扬声器模组1包括：
模组外壳，所述模组外壳设有容腔；
扬声器组件200，所述扬声器组件200设于所述容腔，将所述容腔分隔成前腔111和后腔112；所述模组外壳与所述后腔112对应的部分为后腔壳部120；以及
支撑柱300，所述支撑柱300设于所述后腔112且与所述后腔壳部120连接，以支撑所述后腔壳部120。
在本实施例中，模组外壳设有容腔，该容腔用于容纳扬声器组件200(图中仅示出了振膜的结构)，扬声器组件是一种在通电情况下产生振动继而发出声音的部件。将扬声器组件200设于容腔中，从而将容腔分成前腔111和后腔112，与前腔111连通设有出声口131，扬声器组件200发出的声音经过前腔111传递出去。可以理解的是，扬声器组件200设于容腔中，即固定于容腔中，固定的方式有多种，例如将扬声器组件200固定于模组外壳。
模组外壳与后腔112对应的部分为后腔壳部120，相应地，与前腔111对应的部分为前腔壳部。支撑柱300设于后腔112，且连接于后腔壳部120，由于支撑柱300的支撑作用，沿支撑柱300的轴向，支撑柱300能承受较大的作用力，如此，将支撑柱300连接于后腔壳部120后，加强了后腔壳部120的结构强度。支撑柱300的数量可以为一个或多个。在扬声器组件200产生振动并将振动传递至后腔壳部120时，由于支撑柱300的结构加强作用，大大抑制了后腔壳部120谐振。又由于，只要设置支撑柱300，后腔壳部120的结构强度都得到提高，因此，支撑柱300的尺寸可以做到足够小，降低支撑柱300对后腔112的体积的占用，从而实现基本不减小后腔112体积的前提下抑制谐振，减弱噪声的发生，降低失真，改善声学性能。
在本实用新型一实施例中，如图1和图3，所述后腔壳部120具有顶板121、侧板122和底板123，所述顶板121与所述侧板122连接，所述侧板122与所述底板123连接；
所述支撑柱300的一端连接于所述顶板121，另一端连接于所述底板123。
在本实施例中，为了实现更好的声学性能，一般来说，后腔壳部120的顶板121和底板123跨度较大，因此顶板121和底板123是最容易发生谐振的部位。本实施例通过将支撑柱300连接顶板121和底板123，加强了顶板121和底板123的结构强度，从而抑制谐振的发生。
在本实用新型一实施例中，继续参见图1和图3所示，所述支撑柱300分别与所述顶板121和所述底板123垂直。在本实施例中，如上所述，支撑柱300能承受较大的轴向作用力，顶板121和底板123在发生谐振时，顶板121和底板123相对于后腔112高频率上下振动，如此将支撑柱300设置为与顶板121和底板123垂直，能最大限度的抑制谐振的发生，防止出现噪音。
在本实用新型的一实施例中，如图1和图2所示，在所述支撑柱300的数量为一个时，如上所述，在后腔112中设置支撑柱300并连接顶板121和底板123后，即能提高后腔壳部120的结构强度，因此，为了减少支撑柱300对后腔112体积的占用，将支撑柱300的数量设置为一个，并且尽可能地，将该支撑柱设置于后腔112的中心位置，使得支撑柱300对顶板121和底板123的支撑更为平衡。如此，既能抑制谐振，也能保证后腔112的体积。
在本实用新型的一实施例中，所述支撑柱300的数量为两个，两个所述支撑柱300相间设置。在本实施例中，将支撑柱300的数量设置为两个，两个支撑柱300相间设置，以更大支撑范围支撑顶板121和底板123，进一步避免谐振的发生。在通过设置两个支撑柱300，使得单个支撑柱300的尺寸可以做得更小，相对于一个支撑柱300，在缩小支撑柱300尺寸的前提下，两个支撑柱300所占用的后腔121空间不会变化过大，而且由于支撑的范围更广，可以更有效地抑制谐振。
在本实用新型的一实施例中，如图3和图4所示，所述支撑柱300的数量为多个，多个所述支撑柱300相间设置。与上一实施例类似，本实施例的支撑柱300的数量更多，为多个(即三个以上)，这样便可进一步地降低单个支撑柱300的尺寸，而且相对于后腔112体积较大扬声器模组，多个支撑柱300的相间 设置更能更加均衡地支撑后腔壳部120，有效地抑制谐振。
在本实用新型的一实施例中，继续参见图3和图4所示，在所述支撑柱300的数量为多个时，多个所述支撑柱300呈三角形分布。在本实施例中，多个支撑柱300呈三角形分布，可以理解的是，这里的三角形分布可以为全部支撑柱300整体呈三角形分布，形成一个三角形；也可以为全部支撑柱300形成多个三角形，如每三个支撑柱300形成一个三角形。如此，通过支撑柱300的三角形分布，进一步地提高了后腔壳部120的结构强度，进一步地抑制谐振。
在本实用新型的一实施例中，如图3和图4所示，所述支撑柱300的数量为三个。在本实施例中，所述支撑柱300的数量为三个，三个支撑柱300间隔且均匀分布于后腔112中。如此，在保证后腔壳部120足够的结构强度的前提下，防止支撑柱300对后腔112体积的占用。
在本实用新型的一实施例中，如图1至图4所示，所述支撑柱300为圆柱体。在本实施例中，在扬声器组件200的振动过程中，后腔112中存在微弱气流的流动，将支撑柱300设置为圆柱体，即支撑柱300的表面是呈圆滑过渡的，在气流遇到支撑柱300的阻挡时，能沿着支撑柱300的表面流动，从而降低对气流的阻碍，保证声学性能。
在本实用新型的一实施例中，所述支撑柱300的材质为金属、塑料或橡胶。在本实施例中，支撑柱300设置在后腔112并与顶板121和底板123连接，如此提高后腔壳部120的结构强度，因此支撑柱300可以选用多种材质，只要能对顶板和底板形成支撑即可，例如为金属、塑料或橡胶。
在本实用新型的一实施例中，所述支撑柱300分别与所述顶板121和所述底板123一体成型。在本实施例中，支撑柱300分别与顶板121和底板123一体成型，使得整体性更强，结构强度更好。例如，支撑柱300、顶板121和底板123通过注塑一体成型。
在本实用新型的一实施例中，所述支撑柱300分别与所述顶板121和所述底板123粘接。在本实施例中，在支撑柱300的两端涂覆胶黏剂，通过胶黏剂分别粘接于顶板121和底板123，待胶黏剂固化后，支撑柱300即固定于顶板121和底板123之间，从而形成对顶板121和底板123的支撑。
在本实用新型的一实施例中，所述支撑柱300分别与所述顶板121和所述底板123超声连接。超声连接又称超声波熔接、超声波焊接，超声连接把超声 波能量传送至顶板121和支撑柱300之间、底板123和支撑柱300之间，利用焊接的交界面处声阻大的特点，从而产生局部高温使得支撑柱300分别与顶板121和底板123融合在一起，这其中不需要添加溶剂、粘接剂或其他辅助品，可以完全代替胶黏剂粘合。
在本实用新型的一实施例中，所述扬声器组件200包括振动系统和磁路系统。
在本实施例中，振动系统包括振膜和音圈，音圈带动振膜振动从而发声。磁路系统。磁路系统包括内磁路部分和边磁路部分，内磁路部分和边磁路部分之间形成此间隙，音圈悬设于磁间隙内，音圈连通变化的电流从而实现振动。振动系统和磁路系统设于容腔，可以理解的是，即将振动系统和磁路系统固定于容腔，例如与模组外壳固定。
在本实用新型的一实施例中，所述扬声器组件200还包括辅助系统。在本实施例中，扬声器组件200还包括辅助系统，辅助系统收容振动系统和磁路系统，使得扬声器组件200形成一个扬声器单体。这里的辅助系统一般呈壳体状，从而更便捷地固定于容腔中。
以上所述仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是在本实用新型的实用新型构思下，利用本实用新型说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本实用新型的专利保护范围内。
