所述散热部42形成所述导声通道50的表面与所述第一倾斜壁2144形成所述导声通道50的表面位于同一平面上，即所述散热部42完全收容于所述收容槽2143内，所述收容槽2143的凹陷深度与所述散热部42的厚度相等，使得所述散热部42与所述第一倾斜壁2144齐平，不会阻挡到所述导声通道50，从而可以有效的保证所述导声通道50的体积，在能实现散热的基础上，也不会影响到所述导声通道50的发声。
所述弯折部432的表面与所述侧壁213的外表面齐平。具体的，具有所述凹陷槽2131的所述侧壁213远离所述收容空间10一侧的表面与所述弯折部432的远离所述收容空间10一侧的表面位于同一平面上，即所述弯折部432完全收容于所述凹陷槽2131内，所述凹陷槽2131的凹陷深度与所述弯折部432的厚度相等，使得所述弯折部432与所述侧壁213齐平，不会延伸出所述侧壁213外，使得所述扬声器箱100外部更加的平整，让所述扬声器箱100更好装配。
所述本体部431包括与所述导热部41连接的第一部分4311及与所述第一部分4311的远离所述导热部41的一侧连接的第二部分4312，所述弯折部432自所述第二部分4312的远离所述第一分部4311一侧弯折延伸形成，所述第一部分4311与所述导热部41的宽度相等，所述第二部分4312与所述弯折部432、所述散热部432的宽度相等，且所述第二部分4312的宽度大于所述第一部分4311的宽度，从而使得所述导热件40能更好的与所述壳体20连接固定，并且也增加了所述散热部42的面积，从而增加了所述导热件40的散热性能。
在本实施例中，所述导热件40为实心结构。当然，在其他实施例中，所述导热件40可为空心结构，所述导热件40具有中空区域，且所述中空区域中填充有冷凝液，增加所述导热件40的散热效果。甚至，所述导热件40还可为其他任意能实现传导热量的结构，即只需设置所述导热件40将所述发热部件的热量传导至所述扬声器箱100中，通过所述扬声器箱100实现散热即可。
所述扬声器箱100散热的工作原理：所述扬声器箱100在散热工作时，可输入较低频（低于1000Hz）的脉冲信号，驱动所述振膜31振动，在该脉冲信号下，所述振膜31仅会振动，但不会发出声音，所述振膜31振动推动所述前声腔11与所述导声通道50的空气与所述扬声器箱100外的空气对流，实现风冷散热。在所述扬声器箱100不执行播放声音任务时可单独输入较低频的脉冲信号，让所述扬声器箱100仅用于散热。而在所述扬声器箱100执行播放声音任务时可将较低频的脉冲信号叠加进音乐信号中，由于该脉冲信号为超低频，将不会被人耳听到，不会影响到所述扬声器箱100的播放效果。
具体的，所述振膜31在向靠近所述顶壁211方向振动时，将由所述导热件40引入所述前声腔11中的相对较热空气排出所述扬声器箱100外，而所述振膜31在向远离所述顶壁211方向振动时，将所述扬声器箱100外相对较冷的空气往通过所述导声通道50往所述前声腔11内吸入，以此往复实现散热效果。
请结合参阅图4。同时本申请还提供了一种移动终端200，其包括具有容纳空间的外壳110、收容于所述外壳110内的发热部件120和所述扬声器箱100。所述扬声器箱100的所述导热件40与所述发热部件120连接，所述发热部件120产生的热量通过所述导热件40传输至所述扬声器箱100中，所述扬声器箱100通过所述振膜31的振动进行风冷散热。
所述外壳110上设有出声孔111，所述出声孔111与所述导声通道50连通，所述扬声器箱100通过所述出声孔111出声，并通过所述出声孔111将热空气排出所述移动终端200。
在本实施例中，所述发热部件120为中央处理器。当然，在其他实施例中，所述发热部件120可为电池或所述移动终端200中任意需要散热的部件。
需要说明的是，在本实施例中所述导热件40仅连接有中央处理器。当然，在其他实施例中，所述导热件40可同时连接多个需要散热的部件，如中央处理器、电池或其他任意需要散热的部件，通过一个所述扬声器箱100对多个需要散热的部件进行散热。
可以理解的是，所述扬声器箱100的所述导热件40中的所述导热部41的形状和长度可根据实际需求进行选择，只需所述导热部41能将所述发热部件120产生的热量传导至所述扬声器箱100中即可。
与相关技术相比，本申请提供的扬声器箱通过设置所述导热件，让所述导热件将发热部件产生的热量导入所述扬声器箱内，通过所述扬声器箱实现将热量排出，使得所述扬声器箱不仅能用于发声还能用于散热，从而增加了所述扬声器箱的用途，让所述扬声器箱具备更好的应用前景。
相对应的，本申请提供的移动终端通过采用所述扬声器箱，由于所述扬声器箱既能实现发声同时还能用于散热，所述移动终端内的发热部件发热工作时，所述扬声器箱能将所述发热部件散发的热量排出所述移动终端。所述扬声器箱不仅可以保证所述发热部件的工作性能，同时也节省了所述移动终端的内部空间。
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。
