本实用新型的实施方式
下面结合附图和实施方式对本实用新型作进一步说明。
请参阅图1至图11，该扬声器装置，其包括：上盖板1、与上盖板1围成收容腔的下盖板2、收容于收容腔内的发声单体3及部分收容于收容腔内的柔性电路板4，柔性电路板4包含：与发声单体3连接的主体部41、与外部电路电连接的连接部43及衔接主体部41和连接部43的固定部42，上盖板1与下盖板2合并形成供部分固定部42延伸至收容腔外的开口5，固定部42位于收容腔内靠近开口5的一侧面设有与开口5处的下盖板2贴合固定的双面胶6，固定部42的另一侧面设置有与上盖板1侧壁11相抵接的补强板7。
在本实用新型的实施例中，在柔性电路板4上设置补强板7，并利用扬声器装置中的靠近开口5处的侧壁11对补强板7进行水平面上的固定，以实现限制柔性电路板4的固定部42延伸至腔外的长度，使得连接部43刚好与其他电子设备的端口电连接；该种固定方式在对柔性电路板4在扬声器腔内进行固定时，可有效减少占用扬声器装置的后腔空间。
进一步的，上盖板1包括：上盖面12及自上盖面向下盖板方向延伸的侧壁11，上盖板1与下盖板2形成开口5的侧壁11处具有一固定侧壁111，位于固定部42的补强板7与固定侧壁111相抵接。
在本实用新型的实施例中，柔性电路板4的固定部42靠近扬声器装置的开口处的固定侧壁111，通过设置补强板7在柔性电路板4的固定部42上，使得补强板7与固定侧壁相抵接，提高了固定部42的强度，且限制柔性电路板4的连接部43在水平面上的延伸长度，使得连接部43刚好与扬声器装置外的其他电子设备的连接端口连接。
进一步的，补强板7的侧面与固定侧壁111贴合。在本实用新型实施例中，柔性电路板4的连接部43向扬声器装置腔外延伸时需要穿越该固定侧壁111，该固定侧壁111为侧壁11中与补强板7可匹配的唯一侧壁，补强板7与固定侧壁111贴合，完成补强板7与固定侧壁111之间的固定，以实现对柔性电路板4的连接部43在水平方向上的固定。
进一步的，固定部42包括与主体部及连接部43衔接的固定连接部421，及自固定连接部421分别向与固定侧壁111平行方向延伸的第一延伸部422和与第一延伸部422反向延伸的第二延伸部423；
固定侧壁111的两端分别包括向下盖板2延伸且与第一延伸部422抵接的第一凸台511及向下盖板2延伸且与第二延伸部423朝向固定侧壁111的面抵接的第二凸台512，固定部42的宽度大于第一凸台511与第二凸台512之间的距离。在本实用新型实施例中，柔性电路板4的固定部42的宽度大于固定侧壁111的第一凸台511与第二凸台512之间的距离，该第一凸台511与第二凸台512之间的距离可近似为柔性电路板4的连接部43的宽度，则固定部42的宽度大于连接部43的宽度，进一步的，以固定部42作为初步限定柔性电路板4的连接部43在腔外的水平面方向长度的初始端，并结合第一凸台511和第二凸台512可对固定部42的第一延伸部422和第二延伸部423进行限制，使得柔性电路板4的连接部43可延伸的长度更加准确；对于柔性电路板4的固定部42的宽度、连接部43的宽度及第一凸台511与第二凸台512之间的距离，在本实用新型实施例不作赘述。
进一步的，补强板7朝向固定部42的表面形状，与固定部42朝向补强板7的表面的形状相同。在本实用新型实施例中，补强板7与柔性电路板4的固定部42之间的贴合面的形状相同，且面积相同，把补强板7设置在柔性电路板4的固定部42，使得补强板7与固定部42的接触面完好贴合，使得补强板7充分利用了柔性电路板4的固定部42接触面的面积，有效地提高了补强板7对柔性电路板4的固定部42的固定力度。
下盖板2包含与固定侧壁111形成开口5的凹槽平台52，双面胶位于凹槽平台52与柔性电路板4之间，双面胶6将柔性电路板4粘贴固定于凹槽平台52的表面。在本实用新型实施中，利用双方面胶6对柔性电路板4的固定部42进行粘贴，同时对下盖板2的凹槽平台52进行粘贴，以实现在与下盖板2和上盖板1的垂直方向上对柔性电路板4进行有效固定，防止柔性电路板4在垂直方向上对上盖板1和下盖板2进行拍打，产生音差，影响声学性能。
进一步的，双面胶6包括与固定部42形状相同的主胶体61及自主胶体61向凹槽平台52延伸且与凹槽平台52匹配的第三延伸部62，主胶体61及第三延伸部62与柔性电路板4完好贴合。在本实用新型实施例中，下盖板2具有与上盖板1的第一凸台511和第二凸台512组成开口的凹槽平台52，双面胶6的一面与柔性电路板4的固定部42和部分的连接部43粘贴，双面胶6的另一面与凹槽平台52中的表面粘贴，无需在靠近开口5前的腔内特意设置具有坡度阶梯特征的爬坡区，便使得柔性电路板4的固定部42和连接部43在垂直方向上与下盖板2中的凹槽平台52固定，以防止柔性电路板4的固定部42和连接部43在垂直方向上晃动，与开口5拍打而产生音差，该种固定方式在对柔性电路板4垂直方向上固定的同时可有效减少后腔的空间，更进一步的，双面胶6可有效弥补开口5，杜绝超声间隙对声学带来负面的效果，提高了声学的性能。
进一步的，补强板7为玻璃纤维补强板。补强板7主要应在建筑、机械设备、电子产品或工艺加工中，在本实用新型实施例中，补强板7采用的是玻璃纤维补强板（GLASS EPOXY)，该玻璃纤维补强板又称为FR4，该材料为玻璃纤维环氧树脂复合，具有吸水率低、耐久性佳及弯强度好的特点，主要是应用于扬声器装置中辅助柔性电路板4，解决柔性电路板4的柔韧度性，提供柔性电路板的固定部42的强度，在水平方向上对柔性电路板4具有固定作用，以限制柔性电路板4的连接部43延伸在扬声器装置外部的长度，恰好与外部的电子产品端口连接；此外，还方便产品的整体组装，减少对后腔空间的占用，有效的改善了扬声器装置的后腔空间。
本实用新型的有益效果在于：提供一种扬声器装置，通过位于靠近收容腔内部的开口处的柔性电路板设置补强板和双面胶，以对柔性电路板进行水方向和垂直方向上的固定，无需在扬声器装置的后腔空间设置一些平面支撑结构来固定柔性电路板，可有效避免对后腔空间的占用，改善了扬声器装置的后腔空间。
以上的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
