扬声器作为一种将电能转化为声能的器件，现已广泛应用于手机、电脑、MP3等电子装置中，而伴随着科学技术的不断进步以及电子产业的迅猛发展，人们对扬声器的性能也提出了更高的需求。扬声器通常包括磁路系统、振动系统和辅助系统，其中，磁路系统一般包括导磁轭、固定于导磁轭内的磁铁和导磁板；振动系统包括振膜以及音圈，辅助系统则包括外壳以及前盖。现有的扬声器产品，其音圈的引线与弹片电连接，进而与外部电路连通，当接收到外部电路的电流信号后，音圈会在电磁场内做往复切割磁力线的运动，带动振膜振动，从而策动空气发生，实现电声能之间的转换。
但是弹片安装在外壳上后，弹片受力下压时，弹片尾部的圆弧处没有固定结构，弹片下压易产生尾部翘起和整体倾斜，进而可能会造成与整机的焊盘发生短路，或者弹片尾部翘起凸出于外壳亦或者出现脱挂的现象。为了改善此现象，现有技术中通常在弹片的尾部涂固定胶或在外壳上增加定位柱，但是两种方式在制成工艺上都有一定的限制性。

请参阅图1至图5以及图10，本发明提出一种扬声器1，包括：
外壳10，所述外壳10包括一侧板11，所述侧板11上开设有插槽12，所述插槽12包括侧壁121和底壁122，所述底壁122即为插槽12的槽底；
弹性导电端子20，安装于所述插槽12，所述弹性导电端子20具有弹性自由端21，以及在所述侧板11的长度方向上与所述弹性自由端21相对的末端22；
扣台13，凸设于所述插槽12的侧壁121，所述扣台13伸入所述弹性导电端子20的末端，所述扣台13的背向所述插槽12的底壁122的一端形成有导向面131，所述导向面131在远离所述底壁122的方向上，与设置有所述扣台13的侧壁121的间距逐渐减小。
所述扬声器1还包括磁路系统，所述磁路系统收容于所述外壳10内，所述磁路系统包括导磁轭30、固定于所述导磁轭30内的磁铁40以及覆盖于所述磁铁表面的导磁板50，所述外壳10内还设置有音圈与振膜(图中未标示)。所述弹性导电端子20放入终端装置后，其弹性自由端21会受到下压力而向压， 进而与用于放置所述扬声器1的终端装置的导通焊盘接触，从而实现扬声器1内外部电路的导通。弹性导电端子20还包括与末端22连接的固定端，弹性导电端子20通过所述固定端卡扣在外壳10上，或者通过所述固定端焊接在外壳10上，所述固定端上设有焊盘用于与扬声器10内的音圈实现电连接。所述弹性导电端子20的末端22是指限位于所述扣台132的一端，弹性导电端子20的弹性自由端21则卡持在外壳1上或者卡持在所述固定端上的挂门上，对弹性自由端21有一定的限位作用。
所述弹性导电端子20的末端22的形状没有严格要求，只要能够使所述扣台13伸入所述弹性导电端子20的末端22即可，且在弹性自由端21受到下压的过程中，弹性导电端子20的末端22能够限位于所述扣台13，即所述末端22可以呈弧形段，扣台13位于所述弧形段内。另外，所述弹性导电端子20的数量没有严格要求，一般情况下，所述弹性导电端子20设置有两个，且分别设置在呈相对设置的两个侧板11上，呈相对设置的两个侧板11上分别设置有插槽12，两所述弹性导电端子20分别安装在两所述插槽12内。
本发明技术方案通过将所述导向面131在远离底壁122的方向上，与设置有扣台13的侧壁121的间距设置为逐渐减小，使得所述弹性导电端子20的末端22能够在朝向底壁122的方向上，将扣台13卡入所述末端22内。使得弹性导电端子20受到下压时，弹性导电端子20的末端22限位于所述扣台13，防止了弹性导电端子20的末端22翘起以及整体前倾的情况发生，避免了终端装置发生短路的情况。
请参阅图4至图9，为了使所述弹性导电端子20的末端22在靠近所述插槽12的底壁122方向上，能够更加顺畅的压向所述扣台13而使所述扣台13伸入所述末端22。在其中一实施例中，所述导向面131呈平面设置，且因为导向面131在远离所述底壁122的方向上，与设置有所述扣台13的侧壁121的间距逐渐减小，从整体上看，则所述导向面131呈斜面设置。所述弹性导电端子20的末端则沿所述导向面131向所述底壁122的方向滑动，呈斜面设置的导向面131使滑动更加舒畅，滑动到位后则使所述扣台13卡入所述末端22内。
进一步地，请参阅图3和图5，所述扣台13还包括连接所述导向面131、朝靠近所述插槽12的底壁122的方向延伸的台面132，所述台面132背对所述插槽12的侧壁121设置。因为将所述弹性导电端子20的末端22卡于所述扣台13处 后，即所述扣台13伸入所述弹性导电端子20的末端22后，为了保证扣台13的限位效果，所述台面132具有一定的延伸高度，进而防止了弹性导电端子20的末端22从扣台13上脱离出来。且较佳地，所述台面132平行于所述插槽12的侧壁121。
当所述弹性导电端子20的末端向靠近插槽12的底壁122方向上移动时，为了将末端22限位于所述扣台13，则末端22需要从接触导向面131一直向底壁122方向移动，为了进一步的保护弹性导电端子20不会刮到所述扣台13，防止扣台13发生损坏，较佳地，所述导向面131与所述台面132的连接处呈倒圆角设置。将连接处呈倒圆角设置，也更加便于弹性导电端子20组装到所述外壳10上，即更加方便将扣台13卡入弹性导电端子20的末端22。所述弹性导电端子20较佳的为一弹片。
所述弹性导电端子20除了可以从靠近插槽12的底壁122方向上，将末端20卡于所述扣台13，进而将弹性导电端子20安装于外壳10外，也可以在靠近插槽12的侧壁121方向上，即将弹性导电端子20的末端22向靠近插槽12侧壁121的方向上运动，从而使扣台13伸入末端22内，而将弹性导电端子20的末端22限位于扣台13。
具体地，请参阅图6至图10，所述弹性导电端子20的末端22为一朝向所述弹性导电端子20的弹性自由端21开口的弧形段，所述扣台132伸入所述弧形段。将所述末端22设置为弧形段，使得所述末端22在弹性导电端子20受到下压的过程中具有一定的旋转自由度，使弹性导电端子20在长时间使用下不易损坏，延长弹性导电端子20的使用寿命。在上一实施例的基础上，较佳地，所述弧形段为圆弧段，且所述圆弧段的弧度为0.5π～1.5π，即可以为0.5π、0.6π、0.7π、0.8π、π、1.2π、1.3π、1.5π等。呈圆弧段使弹性导电端子20的末端22具有更好的柔度，使其更加不易损坏，且圆弧段是较标准的弧段，使其加工生产时也更加方便。
进一步地，所述弹性导电端子20安装在所述插槽12上后，为了使其末端22与插槽12具有更好的装配效果，请参阅图5，较佳地，所述插槽12的底壁122上凹设有用于容置所述弧形段的凹陷部122a。则所述弹性导电端子20的末端22与所述凹陷部122a相适配，对所述末端22具有一定的保护作用，且为放置所述末端22提供了一定的容纳空间。
所述弹性导电端子20安装于所述外壳10后，所述末端22卡于所述扣台13，则所述末端22与扣台13具有一定的配合关系。在其中一较佳的实施例中，请参阅图3和图5，所述扣台13还包括设于所述插槽12的底壁122上的限位面133，所述限位面133与所述底壁122呈相对设置，所述限位面133呈与所述弧形段的内表面适配的弧形设置。即所述弹性导电端子20在受到下压时，所述末端22则会绕着所述限位面133旋转一定角度，通过将限位面133与弧形段的内表面相适配设置，使两者间产生相对转动时，能够降低两者间受到的损害。
进一步地，所述扣台13在所述插槽12的侧壁121上的投影呈半圆设置，如此不仅使末端22限位于所述扣台13时，两者间具有较佳的配合关系，而且外观更加美观。
本发明还提供一种智能终端，该智能终端包括上述任一实施例的扬声器，因此，上述任一实施例的扬声器的所有有益效果本智能终端也应当一一具有，在此不一一赘述。所述智能终端可以为手机或平板电脑等。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
