可以理解的是，通过设置所述胶合部56覆盖所述固定部553，可以良好的填充所述通孔555。在所述第二振膜54与所述弹性支撑件53以及所述盆架10胶合时胶合面更加平整，不容易发生溢胶，从而提升了产品的外观和性能。
与相关技术相比，本申请的振膜通过设置所述胶合部与所述固定部固定连接，并让所述胶合部覆盖所述固定部的所述通孔设置，使得所述振膜在装配时通过所述胶合部与其他部件胶合固定，胶合面更加的平整，不容易出现溢胶现象，改善了产品外观以及装配胶合状态的一致性，降低了装配难度。
相对应的，本申请提供的扬声器通过采用所述振膜可以有效地避免溢胶的问题，从而提升了所述扬声器的性能。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
