所述导热件3嵌设于所述壳体11且完全覆盖所述通孔110。具体的，所述导热件3包括嵌设于所述壳体11的第一端部31、固定于所述热源2的第二端部32以及连接所述第一端部31和所述第二端部32的连接部33。
所述第一端部31覆盖所述通孔110。所述第一端部31、所述壳体11及所述振膜121共同围成所述前声腔102 。在本实施方式中，所述上盖111、所述第一端部31及所述振膜121共同围成所述前声腔102。
在本实施方式中，所述第一端部31与所述壳体11为一体成型结构。该结构有利于所述扬声器装置100安装和制造，使工艺更为简单，同时也有利于装配好之后的所述扬声器装置100密封性较好，有利于提高所述扬声器装置100的可靠性。
在本实施方式中，所述第二端部32与所述连接部33一体成型，所述第一端部31与所述连接部33分体成型。
在上述结构中，所述第二端部32吸收所述热源2的热量并将所述热量通过所述连接部33传递至所述第一端部31散热。所述振膜121振动推动所述前声腔102内的空气通过所述导声通道101与外界流通。具体的，所述振膜121振动时在所述前声腔102体积的变化：所述前声腔102体积变小时，所述振膜121通过所述导声通道101将所述前声腔102内的部分空气排出至外界；而所述前声腔102体积变大时，所述振膜121通过所述导声通道101将外界的空间吸入至所述前声腔102内；以上过程使所述前声腔102内的空气与外界的空气实现对流。所述振膜121的振动使由所述第一端部31散热于所述前声腔102内的热量随空气流通散发至所述壳体11外。从而实现了所述导热件3对所述热源2的散热，使得所述扬声器装置100的散热效果好。
其中，所述振膜121振动可以是发声形式或者不发声形式，均可以将传导至所述前声腔102内的热量随空气流通散发至外界。从而使所述扬声器箱1可以专门执行散热的工作。具体的，对所述扬声器箱1输入较低频率的脉冲信号，该信号在所述扬声器箱1产生的低频声音不会被人耳听到。在本实施方式中，输入较低频率低于1000Hz。在具体应用上，所述扬声器箱1不执行音乐播放任务时可单独播放该脉冲信号；所述扬声器箱1在执行音乐播放任务时也可将该脉冲信号叠加进音乐信号中。因为该信号是超低频的脉冲信号，将不会被人耳听到，不影响正常听音效果。
更优的，所述第一端部31沿所述振膜121的振动方向向所述振膜121的正投影至少部分落在所述振膜121上。也就是说，所述第一端部31位于所述前声腔102远离所述振膜121的一侧，所述第一端部31与所述振膜121正对或者部分相对，该结构使所述第一端部31在所述振膜121振动下推动空气流动，能够及时和有效地把所述第一端部31在所述前声腔102内附近的空气推动流动，从而有效地使所述第一端部31的热量随空气带走，从而使所述扬声器装置100散热效果更佳。
为了更好的将所述热源2进行散热，在本实施方式中，所述第一端部31至少部分延伸至所述前腔104内且与所述发声单体12间隔设置。该结构使所述第一端部31的一部分处于所述前声腔102内，在所述振膜121振动下推动空气流动，所述第一端部31在所述前声腔102内的一部分处于高速气流中，从而利用所述振膜121振动产生的空气流通达到风冷的效果。
值得一提的是，所述导热件3的结构形式是不限的，其可以为呈中空的一体成型结构，所述导热件3的内填充有导热介质。所述导热介质可以为导热性能好的导热硅脂，也可以为冷却液；而作为一个优选的实施方式，所述导热介质为可以挥发的冷却液，比如水，所述第二端部32吸收所述热源 2的热量后，使得导热介质吸热气化，气化后的导热介质沿中空的所述连接部33传输至所述第一端部31，所述第一端部31将气化的导热介质的热量吸收，使得导热介质放热液化，液化后的导热介质通过所述连接部33回流至所述第二端部32，以此类推，在所述导热件3内部形成一个循环的散热循环。
当然，所述导热件3为呈实心的一体成型结构也是可以的，此时，所述导热件3为导热材料制成，比如为导热性能好的导热硅脂或金属制成，通过所述第二端部32直接吸收热量并通过所述连接部33向所述第一端部31传导。
请同时参阅图3-6，本发明还提供一种移动终端200。所述移动终端200可为手机、平板电脑、电话手表等。
所述移动终端200包括外壳20、盖设于所述外壳20、与所述外壳20共同围成第二收容空间201的屏幕30以及所述扬声器装置100。
具体的，所述扬声器装置100安装于所述第二收容空间201内，所述外壳20设有贯穿其上的出声口202，所述出声口202与所述导声通道101空气连通将所述前声腔102与外界连通，以将所述导热件3散热于所述前声腔102内的热量随空气流通散发至外界，从而避免了热量在所述移动终端200内部积累，有效地使得所述移动终端200的散热效果好。
与相关技术相比，本发明的扬声器装置中，在扬声器箱和热源之间设置了导热件，所述导热件包括嵌设于所述壳体的第一端部、固定于所述热源的第二端部以及连接所述第一端部和所述第二端部的连接部；所述热源依次通过所述第二端部和所述连接部将热量传导至所述第一端部并进入到前声腔中，所述振膜振动推动所述前声腔内的空气通过所述导声通道与外界流通，以使由所述第一端部散热于所述前声腔内的热量随空气流通散发至所述壳体外，从而实现了对所述热源的散热，使得所述扬声器装置的散热效果好。本发明的移动终端包括外壳、盖设于所述外壳并与所述外壳共同围成第二收容空间的屏幕以及本发明所述的扬声器箱装置，所述扬声器箱装置安装于所述第二收容空间内，所述外壳设有贯穿其上的出声口，所述出声口与所述导声通道空气连通将所述前声腔与外界连通，以将所述第一端部散热于所述前声腔内的热量随空气流通散发至外界，从而避免了热量在所述移动终端内部积累，有效地使得所述移动终端内部的热量散发至外界，从而使所述移动终端的散热效果好。
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。
