 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
如图1至图5所示，本实施例的发声装置包括盆架10、磁路***01和振动***40，其中，磁路***01包括磁轭20和磁路结构30，振动***40包括振膜41和音圈43，盆架10具有收容空间，磁路***01和振动***40均收容于收容空间中，振膜41固定于盆架10，音圈43则用于驱动振膜41进行振动发声。具体地，振膜41包括折环410和球顶50，并且，折环410包括第一固定部411、第二固定部413和折环部412，折环410与音圈43连接，球顶50则设于折环的远离音圈43的一侧（实际上，球顶50连接于第一固定部411的外露侧面上，而音圈43则连接于第一固定部411的朝向收容空间的内侧面上），折环410的第二固定部413固定连接于盆架10上，折环部412的两端分别与第一固定部411、第二固定部413连接。在本实用新型中，折环部412由依次相连的第一侧壁4121、顶壁4122和第二侧壁4123组成，第一侧壁4121与第一固定部411连接，第二侧壁4123与第二固定部413连接，顶壁4122的两端则分别连接第一侧壁4121和第二侧壁4123，其中，第一侧壁4121的厚度与第二侧壁4123的厚度相等，且顶壁4122的厚度小于第一侧壁4121的厚度。
在终端设备上应用该发声装置，例如：在手机上应用该发声装置、在平板电脑上应用该发声装置等等，在该发声装置运行而发生的过程中，音圈43在变化电流以及磁路结构30的共同作用下，音圈43带动振膜41振动，从而使振膜41附近的空气振动而发声，在振膜41振动的过程中，通过将振膜41中的第一侧壁4121、第二侧壁4123和顶壁4122三者设置成不同的厚度，即：第一侧壁4121的厚度与第二侧壁4123的厚度相等，且第一侧壁4121的厚度大于顶壁4122，如图6所示，第一侧壁4121的厚度为H2，第二侧壁4123的厚度H1，顶壁4122的厚度为H3，即H1=H2＞H3，这样即可抑制振膜41的上下振幅左右偏移，从而改善折环部412振动过程中最高点左右不对称的问题，改善产品摇晃，降低失真，从而得以提高音质和立体声效果，进而改善了该发声装置的产品Q值或者SPL等性能。
在本实用新型的实施例中，第一侧壁4121与顶壁4122之间以及第二侧壁4123与顶壁4122之间均以渐变的方式过渡，即：第一侧壁4121的厚度自与顶壁4122连接的一端向第一固定部411连接的一端逐渐增大，第二侧壁4123的厚度自与顶壁4122连接的一端向与第二固定部413连接的一端逐渐增大，并且，第一侧壁4121与顶壁4122之间的连接处以顺滑渐变的方式逐渐缩小厚度而过渡连接，第二侧壁4123与顶壁4122之间的连接处顺滑渐变的方式逐渐缩小厚度而过渡连接。这样以实现抑制振膜41的上下振幅左右偏移的目的，从而改善折环部412振动过程中最高点左右不对称的问题，实现改善产品摇晃来降低失真的效果。
用于生产振膜41的材料可以是PEEK（Polyetheretherketone，聚醚醚酮）、TPE（Thermoplastic Elastomer，热塑性弹性体）、TPU（Thermoplastic polyurethanes，热塑性聚氨酯弹性体橡胶）、硅橡胶等高分子材料。
如图1所示，本实用新型的磁路***01包括磁轭20和磁路结构30，磁轭20连接于盆架10，磁路结构30设置在磁轭20上且磁路结构30位于收容空间中。磁路结构30包括主磁体31和极芯32，主磁体31连接在磁轭20上，极芯32装配在主磁体31的远离磁轭20的一侧，且极芯32被音圈43套住，并且音圈43也套住主磁体31的至少一部分。主磁体31的磁感应作用而驱动音圈43振动，而极芯32的使用能够进一步增强主磁体31的磁感应作用，从而增强主磁体31对于音圈43的磁力驱动力。
进一步地，磁路结构30还包括两个副磁钢33，两个副磁钢33设置在磁轭20的相对两侧，主磁体31安装在磁轭20上，磁轭20的底部、磁轭20的翻边21作为收容空间的腔壁与盆架10连接，并且两个副磁钢33均被放置在收容空间内，当副磁钢33被放置安装完成之后，副磁钢33的边缘与磁轭20之间具有一定的间隙。
在现有技术中，音圈43是直接胶粘固定与振膜41上而不再有其他的辅助固定方式或结构，在音圈43振动的过程中，音圈43与振膜41之间的胶粘连接处受到的应力使得胶粘能力下降，为了能够延长音圈43与振膜41之间的胶粘连接的作用寿命，因此，振动***40还包括加强支撑件44，通过加强支撑件44在音圈43的下端形成了支撑，如此，加强支撑件44与胶粘位置的胶粘作用一起承受音圈43在振动过程中所产生的应力作用。如图1所示，加强支撑件44由于连接头段441、中间弹性承接段442和支撑段443组成，连接头段441与支撑段443通过中间弹性承接段442连接，连接头段441固定连接于盆架10与磁轭20的翻边21之间，支撑段443连接于音圈43的下端。在音圈43振动的过程中，支撑段443对音圈43形成托举，而音圈43与振膜41之间的胶粘连接始终将音圈43稳定连接，相对于现有技术的发声器件而言，利用所增设的加强支撑件44能够进一步延长发声器件的使用寿命。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
