本发明提出一种扬声器模组。
在本发明的一实施例中，如图1至13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(图中仅示出了振膜结构)，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；所述后腔设有填充区1122，所述模组外壳与所述填充区1122对应的部分为填充区壳部120；
吸音材料(图中未示出)，所述吸音材料填充于所述填充区1122；以及，
结构加强部(310、321、322、323、331、332、333、334)，所述结构加强部设于所述填充区壳部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，扬声器组件200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，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。
后腔设有填充区1122，吸音材料填充于填充区1122，如此能有效降低F0，提升低频频响。
对于本领域技术人员来说，吸音材料有多种选择，例如沸石、活性炭、白炭黑等，其形态可以为粉末或颗粒，根据实际情况选择即可。
由于要在有限的填充区1122的体积中填充更多的吸音材料，因此填充区壳部120的壁厚通常较低，如此使得填充区壳部120的结构强度较低。在扬声器组件200产生振动并将振动传递至填充区壳部120时，填充区壳部120受到传递来的振动影响而发生谐振，这种谐振通常是高频率的，不仅产生噪音，还使得填充区壳部120与吸音材料发生擦碰，进一步地增加噪音，长时间工作下甚至引发吸音材料的破裂。因此，本实施例中通过在填充区壳部120中设置结构加强部(310、321、322、323、331、332、333、334)，即通过将结构加强部结合至填充区壳部120，如此提高填充区壳部120的结构强度，增加填充区壳部120发生振动变形的阻力，从而抑制填充区壳部120的谐振，减弱了噪音的发生，改善了声学性能。
在本发明的一实施例中，如图1至图4所示，所述结构加强部包括第一结构加强部，所述第一结构加强部为支撑柱310，所述支撑柱310设于所述填充区1122且与所述填充区壳部120连接，以支撑所述填充区壳部1122。
在本实施例中，结构加强部包括支撑柱310，沿支撑柱310的轴向，支撑柱310能承受较大的作用力。如此，将支撑柱310连接于填充区壳部120时，其相对于填充区壳部120形成轴向支撑，在填充区壳部120具有出现谐振的趋势时，支撑柱310增加了填充区壳部120振动形变的阻力。支撑柱310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填充区壳部120时，由于支撑柱310的支撑作用，大大抑制了填充区壳部120的谐振。又由于，只要设置支撑柱310，填充区壳部120的结构强度都得到提高，因此，支撑柱310的尺寸可以做到足够小，降低支撑柱310对填充区1122的体积的占用，从而实现基本不减小填充区1122体积的前提下抑制填充区壳部120谐振，减弱噪声的发生，降低失真，改善声学性能。
在本发明的一实施例中，如图5至图9所示，所述结构加强部包括第二结构加强部，所述第二结构加强部为筋条(321、322、323)，所述筋条(321、322、323)设于所述填充区壳部120。
筋条(321、322、323)呈条状，将筋条(321、322、323)设置于填充区壳部120(即结合至填充区壳部120)，加强了填充区壳部120的抗形变能力，从而提高填充区壳部120的结构强度。在扬声器组件200产生振动并将振动传递至填充区壳部120时，填充区壳部120具有形变的趋势，但是由于筋条(321、322、323)的设置，筋条(321、322、323)阻碍了填充区壳部120形变的发生，从而抑制了谐振的发生。由于单条筋条(321、322、323)呈条状，能覆盖较大的范围，因此在填充区壳部120上设置较少的筋条(321、322、323)即可提高填充区壳部120的结构强度。
筋条(321、322、323)的材质可以为塑料或金属等，或者与填充区壳部120的材质一致，通过一体成型、注塑结合的方式实现在填充区壳部120上设有筋条(321、322、323)。
在本发明的一实施例中，如图10至13所示，所述结构加强部包括第三结构加强部，所述第三结构加强部为凸起结构(331、332)，所述凸起结构(331、332)凸设于所述填充区壳部120的表面。
本实施例中在填充区壳部120的表面设有凸起结构(331、332)，凸起结构(331、332)在填充区壳部120的表面凸出，加强了填充区壳部120的结构强度，凸起结构(331、332)可以为一个或多个，这里的填充区壳部120的表面可以是内表面也可以是外表面，本实施例及以下实施例以内表面为例。在扬声器组件200产生振动并将振动传递至填充区壳部120时，由于凸起结构(331、332)的结构加强作用，大大抑制了填充区壳部120的谐振。
凸起结构(331、332)的材质可以与填充区壳部120的材质一致，在制备 填充区壳部120时直接将凸起结构(331、332)成型得出。
在本发明的一实施例中，如图12和13所示，在所述结构加强部包括第三结构加强部时，所述结构加强部还包括第四结构加强部，所述第四结构加强部为内凹结构(333、334)，所述内凹结构(333、334)内凹于所述填充区壳部120的表面。具体为内凹结构333内凹于顶板121，内凹结构334内凹于底板123。
在本实施例中，内凹结构(333、334)内凹于填充区壳部120的表面，可以是内表面，也可是外表面。本实施例及以下实施例以内表面为例。内凹结构(333、334)和凸起结构(331、332)相配合形成凹凸结构。由于填充区壳部120在谐振发生时会出现形变，内凹结构(333、334)配合凸起结构(331、332)，阻碍了填充区壳部120形变的发生，从而进一步地抑制了谐振的发生。此外，通过设置内凹结构(333、334)，相对于增加了填充区1122的体积，从而进一步地提高了声学性能。
在本发明的一实施例中，如图1和图3所示，所述填充区壳部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。
进一步地，在本发明的一实施例中，在所述结构加强部包括第一结构加强部，所述第一结构加强部为支撑柱310时，所述支撑柱310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，填充区壳部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310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。
进一步地，所述支撑柱310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310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相对于填充区1122高频率上下振动，如此将支撑柱310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。
在本发明的一实施例中，所述支撑柱310的数量为两个，两个所述支撑柱310相间设置；
或，所述支撑柱310的数量为多个，多个所述支撑柱310相间设置；
或，所述支撑柱310的数量为多个，多个所述支撑柱310相间设置，且多个所述支撑柱310呈三角形分布。
在本实施例中，在支撑柱310的数量为两个时，两个支撑柱310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310，使得单个支撑柱310的尺寸可以做得更小，相对于一个支撑柱310，在缩小支撑柱310尺寸的前提下，两个支撑柱310所占用的填充区1122体积不会变化过大，而且由于支撑的范围更广，可以更有效地抑制谐振。
在支撑柱310的数量为多个(即三个以上)时，便可进一步地降低单个支撑柱310的尺寸，而且相对于填充区1122体积较大扬声器模组，多个支撑柱310的相间设置更能更加均衡地支撑填充区壳部120，有效地抑制谐振。
多个支撑柱310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310整体呈三角形分布，形成一个三角形；也可以为全部支撑柱310形成多个三角形，如每三个支撑柱310形成一个三角形。如此，通过支撑柱310的三角形分布，进一步地提高了填充区壳部120的结构强度，进一步地抑制谐振。
在本发明的一实施例中，如图1至图4所示，所述支撑柱310为圆柱体；
和/或，所述支撑柱310的材质为金属、塑料或橡胶。
在本实施例中，支撑柱310设置在填充区1122并与顶板121和底板123连接，如此提高填充区壳部120的结构强度，因此支撑柱310可以选用多种材质，只要能对顶板121和底板123形成支撑即可，例如为金属、塑料或橡胶。
在本发明的一实施例中，所述支撑柱310与所述顶板121和所述底板123一体成型。支撑柱310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310、顶板121和底板123通过注塑一体成型。
在本发明的一实施例中，所述支撑柱310与所述顶板121和所述底板123粘接。在本实施例中，在支撑柱310的两端涂覆胶黏剂，通过胶黏剂粘接于顶板121和底板123，待胶黏剂固化后，支撑柱310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。
在本发明的一实施例中，所述支撑柱310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310之间、底板123和支撑柱310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310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。
在本发明的一实施例中，如图5至图9所示，在所述结构加强部包括第二结构加强部，所述第二结构加强部为筋条(321、322、323)时，所述筋条(321、322、323)设于所述顶板121的表面、所述侧板122的表面和所述底板123的表面。具体为，筋条321设置在顶板121的表面，筋条322设置在侧板122的表面，筋条323设置在底板123的表面。
在本实施例中，筋条321设置在顶板121的表面可以为内表面也可以为外表面，对于筋条322和筋条323的设置亦是如此，本实施例以筋条(321、322、323)设置在内表面为例。将筋条(321、322、323)设置在填充区壳部120的内表面，避免占用填充区壳部120外侧的空间，特别对于微型扬声器来说，更有利产品的小型化。
由于只要设置筋条(321、322、323)，便可提高填充区壳部120的结构强度，因此，筋条(321、322、323)的尺寸可以做到足够的小，从而实现基本不减小填充区1122的体积的前提下抑制填充区壳部120谐振的发生，从而减弱噪声的发生，降低失真，改善声学性能。
在本发明的一实施例中，设于所述顶板121的所述筋条321的数量至少为两条。在本实施例中，筋条321相对于顶板121来说，尺寸小得多，因此为了尽可能地使得顶板121的结构强度较为均衡地增加，避免局部结构强度大，局部结构强度小，将筋条321的数量设置为至少两条，那么这些筋条321便可以均匀分布，从而保证了顶板121的结构强度。
在本发明的一实施例中，设于所述顶板121的所述筋条321的数量至少为两条，且至少两条设于所述顶板121的所述筋条321相交设置。如上所述，通过至少两条筋条321的设置，避免顶板121的局部结构强度高，局部结构强度低。本实施例中进一步地通过将至少两条筋条321相交设置，相交的两条筋条321具有不同方向的抗形变能力，从而进一步地提高了顶板121的结构强度。
进一步地，设于所述顶板121的至少两条所述筋条321呈纵横交错状，例如十字状、网格状等。如此，能进一步地提高顶板121的结构强度，防止局部结构强度大，局部结构强度小，更有利于抑制谐振。
在本发明的一实施例中，设于所述底板123的所述筋条323的数量至少为两条。在本实施例中，筋323条相对于底板123来说，尺寸小得多，因此为了尽可能地使得底板123的结构强度较为均衡地增加，避免局部结构强度大，局部结构强度小，将筋条323的数量设置为至少两条，那么这些筋条323便可以均匀分布，从而保证了底板123的结构强度。
在本发明的一实施例中，设于所述底板123的所述筋条323的数量至少为两条，且至少两条设于所述底板123的所述筋条323相交设置。如上所述，通过至少两条筋条323的设置，避免底板123的局部结构强度高，局部结构强度低。本实施例中进一步地通过将至少两条筋条323相交设置，相交的两条筋条323具有不同方向的抗弯能力，从而进一步地提高了底板123的结构强度。
进一步地，设于所述底板123的至少两条所述筋条323呈纵横交错状，例如十字状、网格状等。如此，能进一步地提高底板123的结构强度，防止局部结构强度大，局部结构强度小，更有利于抑制谐振。
在本发明的一实施例中，如图5所示，设于所述侧板122的至少一条所述筋条322与设于所述顶板121的至少一条所述筋条321相接；
和/或，设于所述侧板122的至少一条所述筋条322与设于所述底板123的至少一条所述筋条323相接。
在本实施例中，设于侧板122的至少一条筋条322与设于顶板123的至少一条所述筋条321以及与设于底板123的至少一条筋条323相接，如此使得侧板122的结构强度也得到提高，从而提高整个填充区壳部120的结构强度，进一步地降低填充区壳部120发生谐振的可能性。
在本发明的一实施例中，如图7和图8，在所述结构加强部包括第二结构加强部，所述第二结构加强部为筋条时，
所述筋条(321、323)设于所述顶板121内和所述底板123内，具体为筋条321设于顶板121，筋条323设于底板123。
在本实施例中，将筋条(321、323)设于顶板121内和底板123内，如此 筋条(321、323)便不会占用填充区1122的体积，相对于以上实施例，在保证填充区壳部120的结构强度的前提下，本实施例中的填充区1122的体积更大，从而最大限度地保证声学性能。
在本发明的一实施例中，设于所述顶板121内的所述筋条321的数量为两条，两条设于所述顶板121内的所述筋条321相互间隔且平行；
或，设于所述顶板121内的所述筋条321的数量为多条，多条设于所述顶板121内的所述筋条321相互间隔且平行；
或，设于所述底板123内的所述筋条323的数量为两条，两条设于所述底板123内的所述筋条323相互间隔且平行；
或，设于所述底板123内的所述筋条323的数量为多条，多条设于所述底板123内的所述筋条323相互间隔且平行。
在本实施例中，在顶板121内设置两条相互间隔且平行的筋条321或设置多条相互间隔且平行的筋条321，提高顶板121各个部位的结构强度一致性，避免局部结构强度低局部结构强度高。而且通过筋条321的相互间隔且平衡设置，避免筋条321的相交设置从而导致的顶板121厚度增加，保证声学性能。对于在底板123设置筋条323，与在顶板121设置筋条321类似，不再重复。
在本发明的一实施例中，在所述结构加强部包括第三结构加强部，所述第三结构加强部为凸起结构(331、332)时，所述凸起结构(331、332)凸设于所述顶板121的表面和所述底板123的表面；具体为，凸起结构331设于顶板121的表面，凸起结构332凸设于底板123的表面。
在本实施例中，凸起结构331凸设于顶板121的表面，这里的表面可以为内表面也可以外表面，对于凸起结构332亦是如此，本实施例及以下实施例以内表面为例。将凸起结构(331、332)凸设于顶板121的内表面和底板123的内表面，从而加强了顶板121和底板123的结构强度，在保证扬声器模组1具有良好声学性能的前提下，抑制了填充区壳部120谐振的发生。由于只要设置凸起结构便可提高填充区壳部120的结构强度，因此，凸起结构的尺寸可以做到足够的小，从而实现基本不减小填充区1122的体积的前提下抑制填充区壳部120谐振的发生，从而减弱噪声的发生，降低失真，改善声学性能。
在本发明的一实施例中，设于所述顶板121的所述凸起结构331的数量至少为两个；
和/或，设于所述底板123的所述凸起结构332的数量至少为两个。
如上所述，既要实现对顶板121的结构强度的加强，也要尽可能地降低对填充区1122体积的占用，因此在本实施例中，将凸起结构331的数量设置为至少两个，从而可以对凸起结构331进行均匀排布，每个凸起结构331可以做得足够的小，避免对填充区1122体积的占用，而且能使得顶板121各个部位的结构强度均得到提高，避免局部的结构强度过小局部的结构强度过大的问题。对于底板123设置的凸起结构332亦是如此。
在一实施例中，设于所述顶板121的所述凸起结构331的数量与设于所述底板123的所述凸起结构332的数量相等，并且一一对应设置。在本实施例中，凸起结构331和凸起结构332的数量相等且一一对应，形成一个对称的结构，受力更为均衡，从而可以进一步地抑制谐振。
在本发明的一实施例中，如图10和11所示，所述凸起结构(331、332)呈圆台状。在本实施例中，以凸起结构331为例，将凸起结构331设置呈圆台状，如此，凸起结构331的底面(与填充区壳部120连接的一面)的面积大于凸起结构331的顶面的面积，也即保证凸起结构331具有与填充区壳部120较大的接触面积的前提下，降低对填充区1122体积的占用。
在本发明的一实施例中，在所述结构加强部包括第三结构加强部和第四结构加强部，所述第三结构加强部为凸起结构(331、332)，所述第四结构加强部为内凹结构(333、334)时，所述凸起结构(331、332)凸设于所述顶板121的表面和所述底板123的表面，所述内凹结构(333、334)内凹于所述顶板121的表面和所述底板123的表面。具体为，凸起结构331和内凹结构333设于顶板121，凸起结构332和内凹结构334设于底板123。
在本实施例中，以凸起结构和内凹结构设于内表面为例。凸起结构(331、332)为在顶板121的内表面和底板123的内表面成型得出，内凹结构(333、334)亦为在顶板121的内表面和底板122的内表面成型得出，虽然凸起结构(331、332)和内凹结构(333、334)均能增加顶板121和底板122的结构强度，但是凸起结构(331、332)和内凹结构(333、334)具有对顶板121和底板122发生形变时的不同的形变抑制方向，因此本实施例通过将凸起结构(331、332)和内凹结构(333、334)紧邻设置，以进一步地提高填充区壳部120的谐振抑制能力。
在本发明一实施例中，参见图13所示，所述凸起结构(331、332)的数量为多个，所述内凹结构(333、334)的数量为多个，所述凸起结构(331、332)和内凹结构(333、334)交替设置。如上所述，虽然凸起结构(331、332)和内凹结构(333、334)均能增加顶板121和底板123的结构强度，但是凸起结构(331、332)和内凹结构(333、334)具有对顶板121和底板123发生形变时的不同的形变抑制方向，因此本实施例通过将凸起结构(331、332)设置为多个，内凹结构(333、334)设置为多个，凸起结构(331、332)和内凹结构(333、334)交替设置，如此使得顶板121和底板123的结构强度得到均匀增加。
在本发明的一实施例中，所述凸起结构(331、332)呈凸条状，所述内凹结构(333、334)呈凹槽状，所述凸起结构(331、332)和所述内凹结构(333、334)交替且平行设置。凸条状的凸起结构331和凹槽状的内凹结构333能横跨顶板121，使得顶板121的整体结构强度更为均衡，对于底板123亦是如此。在凸起结构(331、332)和所述内凹结构(333、334)紧邻设置且交替设置时，形成连续的波纹状凹凸结构，不仅仅提高了顶板121和底板123的结构强度，抑制了谐振的发生，而且还能最大限度地增加填充区1122的体积，保证声学性能。
在本发明的一实施例中，所述填充区1122占据所述后腔的全部空间。在本实施例中，填充区1122占据后腔的全部空间，在填充吸音材料后，形成全灌装结构。
在本发明的一实施例中，所述填充区1122的数量为相互间隔的至少两个。在本实施例中，通过设置至少两个填充区，以满足声学性能的需求。
在本发明的一实施例中，所述后腔还设有非填充区1121。在本实施例中，可以理解的是，非填充区1121和填充区1122是相互隔离的，吸音材料填充于填充区1122，非填充区1121不需要填充吸音材料。
在本发明的一实施例中，所述后腔还设有非填充区1121，所述非填充区1121紧邻所述扬声器组件200且隔离所述扬声器组件200和所述填充区1122。
在本发明的一实施例中，所述吸音材料呈多孔球形颗粒状。
在本发明的一实施例中，所述扬声器组件200包括振动***和磁路***。在本实施例中，振动***包括振膜和音圈，音圈带动振膜振动从而发声。磁 路***。磁路***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***和磁路***设于容腔，可以理解的是，即将振动***和磁路***固定于容腔，例如与模组外壳固定。
在本发明的一实施例中，所述扬声器组件200包括振动***、磁路***和辅助***。本实施例与上一实施例类似，区别在于扬声器组件200还包括辅助***，辅助***收容振动***和磁路***，使得扬声器组件形成一个扬声器单体。这里的辅助***一般呈壳体状，从而更便捷地固定于容腔中。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明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发明的专利保护范围内。
