为了方便说明并且理解本申请的技术方案，以下说明所使用的方位词均以附图所展示的方位为准。
下述各个实施例所示的声学装置可以是受话器、扬声器、音响以及其它用于传输声音信号的声音设备。
请参阅图1和图2，该声学装置100包括上壳10、下壳20、声学组件30、声管40、应变消除管50及密封组件60，上壳10与下壳20连接，声学组件30容纳于下壳20与上壳10之间的收容空间70，声管40设置于下壳20的一侧，应变消除管50设置于下壳20的另一侧，密封组件60收容于该收容空间70，密封组件60的一边与下壳20的底面连接，并且该密封组件60的一边能够与下壳20的底面形成无缝接触。声管40用于向用户传输声音，其延伸进入该收容空间70内。应变消除管50用于连接外管80，使外管80连接至声学装置100。其中，声管40或应变消除管50可以采用金属材质或者塑胶材质或者其它类型材质。
请参阅图2，声学组件30包括隔膜框架301及驱动组件302。隔膜框架301的第一表面设置有振动模3011，振动模3011的一端设置有传导孔3011a。驱动组件302包括导电棒3021、线圈3022、永磁体3023、电枢3024及传动杆3025，电枢3024呈U形状，线圈3022缠绕并且固定设置于电枢3024的第一边的一端，永磁体3023设置于电枢3024的第一边的另一端，电枢3024的第一边的一端延伸有连接部30a，传动杆3025的一端连接至该连接部30a，传动杆3025的另一端连接至传导孔3011a。在导电棒3021输入变化音频信号时，线圈3022产生磁力，该磁力通过永磁体3023的作用，驱动电枢3024带动传动杆3025上下振动，进而使传动杆3025带动振动膜3011上下振动从而产生声音信号，声音信号通过声管40传输到外部。
为了实现声学装置100能够传输出更加优质的声音信号，需要将声学组件30的驱动组件302与振动模3011及相关产生或传输声音的环境进行隔离，因此，请一并参阅图2和图2a，隔膜框架301的一边与密封组件60的另一边连接，应变消除管50收容隔膜框架301的另一边，以将收容空间70分隔为第一容纳腔701与第二容纳腔702。其中，振动模3011可以收容于第一容纳腔701，驱动组件302可以收容于第二容纳腔702，由于声学装置100通过密封组件60、隔膜框架301及应变消除管50之间的配合连接，将收容空间分隔为各自密封的第一容纳腔701与第二容纳腔702，并且各个容纳腔的对应声学组件互不影响，从而使声学装置100能够传输优质的声音信号。
在一些实施例中，密封组件60可以是上壳10朝向收容空间70延伸出的凸块，其中，为了配合隔膜框架301及应变消除管50以将收容空间70分隔为各自密封的第一容纳腔701与第二容纳腔702，可以根据设计要求，通过注塑成型工艺在上壳10的预设距离注塑出密封组件60。同理，密封组件60还可以是下壳20朝向收容空间70延伸出的凸块，具体成型原理同上所述，在此不赘述。
密封组件60的安装方式与上述各个实施例的不同点在于，请继续参阅图2，密封组件60设置于声管40朝向收容空间70的一侧，密封组件60与声管40一体化连接。隔膜框架301的一边设置于密封组件60的上侧面60a，因此，隔膜框架301可以很方便地安装于密封组件60上并且与密封组件60形成密封连接。可选地，隔膜框架301的一边通过粘结剂粘结于密封组件60的上侧面60a，因此，其可以进一步将隔膜框架301固定于密封组件60的上侧面60a。
上壳10或下壳20通过注塑成型一体化形成密封组件60，或者，声管40通过注塑成型一体化形成密封组件60，在安装声学装置100时，无需确定密封组件60在声学装置100的位置，并且安装上壳10或下壳20时便安装密封组件60，并且有效地利用隔膜框架301（声学装置100的必备组件）和应变消除管50的形状及位置关系，从而方便安装和提高安装效率。
密封组件60除了可以与上壳10或下壳20或声管40一体成型之外，其还可以一个独立组件，根据设计要求，通过卡扣连接或者其它连接方式安装在上壳10或下壳20或声管40。
请一并参阅图2和图3，在一些实施例中，密封组件60的上侧面60a设置有挡板601，并且至少预留部分区域602，隔膜框架301的一边设置于部分区域602。安装声学装置100时，首先将隔膜框架301放置在部分区域602，应变消除管50收容隔膜框架301的另一边并且将隔膜框架301朝向声管40一侧推挤，使隔膜框架301的一边抵靠挡板601，此时，挡板601能够阻挡隔膜框架301的移动，因此，声学装置100通过密封组件60、隔膜框架301及应变消除管50之间的紧密配合，将收容空间70分隔为各自密封的第一容纳腔701与第二容纳腔702，从而使声学装置100能够传输优质的声音信号。
请参阅图3，挡板601可以是规则形状，亦可以是不规则形状。挡板601可以是与密封组件60一体化连接，亦可以是与密封组件60分离连接。进一步的，此处不对挡板601与密封组件60的连接方式作限定，其可以是螺纹连接，卡扣连接以及等等。
请继续一并参阅图2和图3，部分区域602为平面，挡板601与隔膜框架301的一边相接触的一面为接触面601a，平面与接触面601a的相交角度为90度。当平面与接触面601a的相交角度为90度时，挡板601与隔膜框架301的一边相接触的接触面601a的面积为最大，有效地降低应变消除管50推挤隔膜框架301的压力，提高声学装置100的整体密封的稳定性。当然，部分区域602还可以根据业务需要设置成其它形状。
请一并参阅图2和图4，应变消除管50的上边缘朝向收容空间的一侧延伸有凸出部501，隔膜框架301的另一边收容于凸出部501。进一步的，凸出部501的宽度等于隔膜框架301的另一边的宽度，以便能够将隔膜框架301紧密配合隔膜框架301。只要应变消除管50的凸出部501能够收容于隔膜框架301的另一边，将隔膜框架301紧密地与应变消除管50进行配合连接以实现密封的目的，应变消除管50的凸出部501可以选择任何形状。在一些实施例中，凸出部501可以是收容隔膜框架301的另一边的收容槽。如图4所示，凸出部501还可以是应变消除管50的上边缘朝向收容空间70的一侧延伸出的盖板，该盖板的宽度等于隔膜框架301的另一边的宽度，安装声学装置100时，该盖板覆盖隔膜框架301的另一边的上表面，从而实现隔膜框架301与应变消除管50的紧密配合连接。可选地，如图5所示，应变消除管50还设置档条502，在安装盖板和隔膜框架301的另一边并且进行推挤时，该档条502能够阻挡隔膜框架301的另一边的相对移动，从而实现能够将应变消除管50和隔膜框架301紧密配合连接。
在一些实施例中，通过注塑工艺一体化形成应变消除管50及应变消除管50的凸出部501。在安装声学装置100时，其能够便捷地通过安装声管40、隔膜框架301及应变消除管50便可以实现密封。
在一些实施例中，为了更好地将隔膜框架与声管进行紧密配合连接，图6所示的实施例与上述各个实施例的不同点在于，如图6所示，部分区域602设置有用于收容隔膜框架301的一边的凹槽6021，可选地，该凹槽6021的宽度等于隔膜框架301的一边的宽度。在安装声学装置100时，隔膜框架301的一边能够卡合在该凹槽6021内，以实现隔膜框架301与声管40紧密配合连接。
作为本申请实施例的又一方面，本申请实施例还提供一种电子设备，该电子设备包括上述各个实施例的声学装置。由于声学装置100通过密封组件60、隔膜框架301及应变消除管50之间的配合连接，将收容空间70分隔为各自密封的第一容纳腔701与第二容纳腔702并且各个容纳腔的对应声学组件互不影响，从而使声学装置100能够传输优质的声音信号。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
