图1是本实用新型提供的扬声器的分解结构示意图，图2是图1中A处的侧面剖视图，参见图1和图2。
根据本实用新型的一个方面，提供了一种扬声器，包括：外壳10及容置在外壳10内的振动系统。
其中，振动系统包括振膜20及音圈21，音圈21接合于振膜20的中心部上，音圈21具有引线22。
外壳10的与振膜20的固定部连接的端面上设有导电部11。
引线22的位于所述固定部与所述外壳10之间的部分被配置为导线外露，形成外露导电端23，所述固定部与所述外壳10固定连接时，所述外露导电端23被压接在所述导电部11上，并与所述导电部11电性连接。
本实用新型实施例的技术效果在于，振膜20通过固定部与所述外壳10固定连接后，将音圈21的引线22的外露导电端23固定连接在外壳10的导电部11上，使得引线22与导电部11形成电连接。由于不使用热压焊工艺，导电部11与引线22的外露导电端23不需要预先进行镀锡，从物料和装配上降低成本，可有效规避焊接时虚焊问题，避免焊接不良，保证引线22与导电部11的稳定连接，从而保证扬声器的声学性能的稳定性。
下面对本实用新型实施例提供的扬声器做进一步的详细介绍。
本实用新型实施例中，振膜20通过固定部与外壳10在连接时，可通过超声工艺、热熔工艺及涂胶工艺等常规装配工艺连接即可。在一种可实现的方式中，音圈21具有两个引线22，外壳10设置有两个导电部11，两个引线22通过外露导电端23分别连接在不同的导电部11上，分别实现电连接。
继续参见图1，可选地，从引线22的出线端至外露导电端23，引线22具有依次连接的延伸段24和弯折段25，延伸段24沿着振膜20的折环 部延伸，使引线22整体能够更好的配合振膜20的振动一同振动，减弱引线22对振膜20和音圈21的振动的妨碍。弯折段25从音圈21与振膜20之间延伸到导电部11上，弯折段25上具有外露导电端23。外露导电端23与外壳10的导电部11连接后，用于导入声音信号。
为了防止在发生振动时，减少对外露导电端23的拉扯力，可选地，外壳10设置有支撑平台12，支撑平台12从导电部11沿着延伸段24的延伸路径延伸，延伸段24部分与支撑平台12连接。当引线22向靠近支撑平台12方向振动时，引线22的延伸段24被支撑平台12阻挡，支撑平台12为引线22的延伸段24提供支撑力，支撑平台12改变了振动的支点的位置，使得振动的支点的位置远离了外露导电端23，从而减小了外露导电端23的拉扯力，避免引线22与导电部11脱离。
继续参见图1和2，可选地，固定部朝向外壳10的一侧环设有连接壁26，固定部通过连接壁26与外壳10连接。连接壁26可增大振膜20的固定部的厚度，从而使得固定部与外壳10的连接方式变多，连接壁26与外壳10之间可通过超声工艺、热熔工艺及涂胶工艺等方式实现连接，可增强固定部与外壳10之间的连接强度。
为进一步增强连接壁26与外壳10的连接强度，可选地，外壳10上设置有多个连接挡板13，连接挡板13与连接壁26朝向音圈21的一侧连接。通过连接挡板13可以对连接壁26的连接位置实现定位，从而确保振膜20的连接位置的稳定。
本实用新型实施例中，可选地，外壳10的与振膜20的固定部连接的端面上设置有两个导电部11，且位于两个导电部11之间设有隔断挡板14，隔断挡板14与连接壁26朝向音圈21的一侧连接。通过隔断挡板14可防止在装配过程中，音圈21的引线22被连接在同一个导电部11上。且通过隔断挡板14还可以进一步增强连接壁26与外壳10的连接强度。
本实用新型实施例中，可选地，外壳10内嵌金属件，导电部11的一种可实现方式为所述金属件的与所述外露导电端23电连接的金属面，且金属面上不需要预先镀锡。外露导电端23的一种可实现方式为引线22的去除外层绝缘层后的金属线。例如，引线22可为一种漆包线，通过使用激光 将漆包线外部的绝缘层剔除，剔除绝缘层的部分露出内部的金属线，金属线被夹在振膜20的固定部与外壳10的导电部11之间，通过固定部将金属线固定在外壳10的导电部11上，以便引线22通过金属线与导电部11形成电连接。
本实用新型实施例中，引线22与音圈21可以为一体设置，即引线22与绕制音圈21的线材为一整体。引线22与音圈21还可以为分体设置，即引线22与绕制音圈21的线材为不同的线体。
引线22与音圈21为分体设置时，可选地，音圈21具有连接引脚，连接引脚与引线22连接。连接引脚用于将从引线22导入的声音信号传递到音圈21上。连接引脚从音圈21上伸出，连接引脚可以通过焊接、粘接的方式与引线22连接，以形成电连接。本实用新型的连接引脚和弯折段25不直接形成固定连接，从而减小了引线22受到的振动作用力，减小引线22断线的风险。
一种可实现的方式，音圈21具有两支引线22，相应地，音圈21上具有两支连接引脚。两支引线22分别焊接在两支连接引脚上，其中一支引线22与一支连接引脚形成电连接；将另一支引线22与另一支连接引脚形成电连接。这样，两支引线22通过不同的连接引脚分别电连接到音圈21的两个位置，为声音信号在音圈21上的导通形成完整回路。
引线22和音圈21采用分体设置时，进一步地，可以采用具有不同性能、尺寸的线材制成引线22和音圈21。进而使引线22和音圈21突出表现不同的性能特点。例如，引线22的抗拉伸强度大于绕制音圈21的线材的抗拉伸强度，绕制音圈21的线材的导电率大于引线22的导电率。引线22采用抗拉伸强度较大的材料制成，引线22的直径可以相对较大。引线22在随振膜20振动的过程中出现断线的风险降低。而用于绕制音圈21的线材则采用导电率相对较大的材料制成，音圈21的线材的直径可以相对较小。音圈21的导电率提高有助于改善振动组件对声音信号的响应灵敏度，提高其声学性能。
可选地，扬声器还包括磁路系统，磁路系统固定设置在外壳10内。参见图1，图1中磁路系统出侧壁30外其他部件均未示出，磁路系统包括 导磁轭、磁铁及华司，导磁轭包括底板及侧壁30，磁铁设置在底板上，华司设置在磁铁背向底板的一侧上，音圈21悬置于磁铁与导磁轭的侧壁30形成的间隙内。
侧壁30的远离底板的端面与引线22的部分抵接。侧壁30为引线22提供了支撑。侧壁30对引线的作用与支撑平台12的作用类似，例如，当引线22向靠近侧壁30方向振动时，引线22的延伸段24被侧壁30阻挡，侧壁30为引线22的延伸段24提供支撑力，侧壁30改变了振动的支点的位置，使得振动的支点的位置远离了外露导电端23，从而较小了外露导电端23的拉扯力，避免引线22与导电部11脱离。另外，通过侧壁30对引线22的支撑作用，使得引线22对音圈21及振膜20的振动造成的干扰相对较小，可减弱在振膜20振动时，引线22对振膜20和音圈21的振动的妨碍。
进一步地，本实用新型还提供了一种扬声器模组，包括模组壳体以及上述中的扬声器，扬声器设置在模组壳体中，模组壳体具有出声口，扬声器发出的声音从出声口传出。
不同于扬声器，扬声器模组可以由模组壳体构成有前出声腔、后声腔等结构，扬声器可以设置在模组壳体中。在扬声器模组中，振动系统与磁路系统的配合方式与扬声器中的方式可相互参考，此处不一一进行赘述。
虽然已经通过示例对本实用新型的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本实用新型的范围。本领域的技术人员应该理解，可在不脱离本实用新型的范围和精神的情况下，对以上实施例进行修改。本实用新型的范围由所附权利要求来限定。
