参见图1-3，为本发明提供的一种扬声器的较佳实施例，该扬声器包括扬声器单体10和接触端子20，所述接触端子20设于所述扬声器单体10的背离出音孔的第一表面101，所述接触端子20包括底壁1，底壁1的一侧折弯形成侧壁2，侧壁2设有通槽21，底壁1的另一侧折弯形成力臂3，力臂3与侧壁2相对设置，力臂3的端部向侧壁2延伸并伸入通槽21内，力臂3的端部与通槽21的远离底壁1的一侧内壁相抵，底壁1设有支撑臂4，支撑臂4与力臂3对应设置，支撑臂4的一端向力臂3延伸，当力臂3向底壁1方向被挤压时，力臂3可与支撑臂4的端部相抵，此时支撑臂4具有使力臂3远离底壁1的弹力。
本发明提供的扬声器，通过在接触端子20的底壁1上开设支撑臂4，支撑臂4和力臂3在向底壁1方向被挤压后具有弹力，这样使得接触端子20具备两个臂，在使用中，力臂3被往底壁1方向挤压时，支撑臂4的端部可与力臂3相抵接，支撑臂4对力臂3实现支撑，同时支撑臂4的回复力推动力臂3，使得力臂3在短时间内能快速的达到要求的力值，同时支撑臂4还能减少力臂3的疲劳应力，在将扬声器单体10装配在终端设备上时，力臂3通过支撑臂4与终端的连接端子之间快速达到要求的力值而形成接触导通，支撑臂4向力臂3提供的辅助弹力能够在力臂3承受更小的疲劳应力的情况下减小力臂3与连接端子之间的接触电阻而保证导通良好，避免接触端子20在使用中过快失效，延长了扬声器的使用寿命。
进一步地，力臂3与底壁1的交接处设置为第一圆弧31。设置第一圆弧31，可以降低力臂3在被反复挤压时力臂3与底壁1连接处的疲劳应力，提高力臂3被往底壁1方向挤压时回复原位的弹力。
进一步地，力臂3的向侧壁2延伸且靠近通槽21的一端折弯形成第二圆弧32，第二圆弧32的靠近通槽21的一端向通槽21延伸并伸入通槽21内，且第二圆弧32远离底壁1凸出。设置第二圆弧32，可以拉开力臂3与底壁1之间的距离，增大力臂3被挤压的行程。
其中，力臂3伸入通槽21的部分延伸出所述通槽21外，并且，该部分远离底壁1的第二表面33与通槽21的背离所述底壁1的槽壁相抵接。如此，可以避免力臂3在使用中脱离通槽21，提高力臂3与通槽21配合的稳定性。
进一步地，支撑臂4向力臂3延伸的端部弯曲形成第三圆弧41，第三圆弧41可与力臂3相抵接。在支撑臂4可与力臂3抵接的一端设置第三圆弧41，除了可以增大支撑臂4的端部与力臂3的接触面积外，还能够加强支撑臂4端部的强度。
进一步的，通槽21自侧壁2延伸至底壁1。如此，当力臂3被往底壁1方向挤压时，可以避开力臂3伸入通槽21内的端部。
进一步地，支撑臂4的端部与力臂3的中部相对应，即，支撑臂4的端部位于第一圆弧31和第二圆弧32之间，这样使得支撑臂4对力臂3的支撑力达到最适合的力值。
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。
