本实施例与实施一的区别在于，本实施例的扬声器100b，参见图5环绕图6，所述中心振动部211还包括第一凹陷部2113，第一凹陷部2113自所述第一内壁2141向靠近所述折环部212凹陷形成，所述垫边23还包括第二凹陷部234，第二凹陷部234自所述第二内壁232向靠近所述折环部212凹陷形成，且第二凹陷部234与所述第一凹陷部2113正对设置。所述球顶22还包括延伸部224、两相对的长边端225及两相对的短边端226，延伸部224自所述外壁221向靠近所述折环部212延伸形成，且延伸部224分别与所述第一凹陷部2113和第二凹陷部234相配合，所述延伸部224包括形成于所述长边端225的第一延伸部2241和形成于所述短边端226的第二延伸部2242，从而增加球顶22的胶合强度，降低产品对胶水等粘结剂的粘结能力的需求，降低成本，同时改善产品可靠性分离的问题。
借此，本实用新型通过在振膜21上一体成型一与球顶22相对设置的垫边23，垫边23提高振膜21刚性的同时，垫边选材较多，耐温耐压能力更强，强度更高，结构也更多元化，也不会因为一体成型过程中的工艺问题对球顶造成污染或者损坏，量产可行性更高。同时，将所述球顶胶合于振膜21的第一贯通孔214内，提供更高的产品上下空间，满足部分产品上下空间不同的需求，提高产品振幅空间，改善产品性能，通过在球顶22设置延伸部224与振膜21和垫边23相配合，从而增加球顶22的胶合强度，降低产品对胶水等粘结剂的粘结能力的需求，降低成本，同时改善产品可靠性分离的问题。
以上所述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。
