在本实用新型可选实施例中，该移动终端10包括的壳体101，用于支撑移动终端10整体机械强度。
可选地，移动终端10可以是智能手机、平板电脑、个人数字助理、电子书等具有多种操作系统的硬件设备。
随着半导体技术的不断发展，移动终端10平台的核数越来越多，处理速度越来越快，性能趋近于个人计算机(personal computer，PC)，随着移动终端10性能的提升，中央处理器(Central Processing Unit，CPU)的功耗和发热会更加严峻，有必要高效地解决移动终端10的发热问题。
在一个可选的实施例中，该移动终端10中的散热模块102可以用于对移动终端10的热源进行散热，热源例如移动终端10的CPU。
可选地，一些实施例中，参见图2，该移动终端10还包括与散热模块102相连的控制器103，控制器103设置为判断当前温度值是否大于预设温度阈值，并在当前温度值大于预设温度阈值时，控制振膜1022振动。
由控制器103对散热模块102中与喇叭音腔1021相连的振膜1022进行控制，以对热源进行散热。
在一个可选的实施例中，散热模块102包括的喇叭音腔1021可以设置在移动终端10喇叭的后部，喇叭音腔1021可以用于使移动终端10的喇叭发出声音，喇叭音腔1021也可以用于在振膜1022振动时带动内部的空气压缩或者扩充，以对热源进行散热。
可选地，在移动终端10的喇叭工作时，喇叭音腔1021内部的空气被压缩或者扩充，能够使移动终端10的喇叭发出声音，在喇叭音腔1021内部的 空气压缩时，喇叭音腔1021内部的空气压强增大，喇叭音腔1021内部的空气压强大于热源上的空气腔1023内部的压强，此时，喇叭音腔1021内部的空气压缩触发喇叭音腔1021内部的空气通过倒相孔1026传输至热源上的空气腔1023，空气腔1023内部的热空气被压缩从壳上的空气交换孔1025排出，同时将热量也带出壳体101外，在喇叭音腔1021内部的空气扩充时，喇叭音腔1021内部的空气压强减小，喇叭音腔1021内部的空气压强小于热源上的空气腔1023内部的压强，此时，空气腔1023内部的压强也会变小，壳体101外面的空气就会通过壳体101上的空气交换孔1025进入到热源上面的空气腔1023内部，对热源进行降温，这种两个过程周而复始，实现热源上面空气腔1023内部的热空气和壳体101外的冷空气交互的目的。因此，可以理解的是，在喇叭音腔1021内部的空气被压缩或者扩充时，可以触发喇叭音腔1021内部的空气与热源上的空气腔1023内部的空气进行对流。
在一个可选的实施例中，散热模块102还包括：
与喇叭音腔1021相连的振膜1022，振膜1022用于振动，以压缩/扩充喇叭音腔1021内部的空气。
在喇叭音腔1021上的振膜1022产生振动时，可以压缩或者扩充喇叭音腔1021内部的空气，触发喇叭音腔1021内部的空气与热源上的空气腔1023内部的空气进行对流。
在一个可选的实施例中，散热模块102还包括：
与移动终端10的热源相连的空气腔1023，空气腔1023用于在喇叭音腔1021内部的空气压缩/扩充时，与喇叭音腔1021之间产生对流的空气以对热源进行散热。
可选地，热源可以例如移动终端10的CPU，或者，热源也可以例如移动终端10中需要散热的部件，本实用新型实施例对此不作限制。
可选地，空气腔1023可以通过导热硅脂连接在热源上部，空气腔1023的下部可以为具有导热功能的金属，可以有效实现热源与空气腔1023之间的热交换，提升移动终端10的散热效果。
在一个可选的实施例中，散热模块102还包括：
连接喇叭音腔1021和空气腔1023的导气通路1024，导气通路1024用于在喇叭音腔1021内部的空气压缩时，将喇叭音腔1021内部的空气输出至空气腔1023，在喇叭音腔1021内部的空气扩充时，将壳体101外的空气抽入至空气腔1023，以及把空气腔1023中的空气抽入到喇叭音腔1021中。
可选地，导气通路1024可以为软管，占用空间小，易于在移动终端10的壳体101中进行布置。
与空气腔1023相连的空气交换孔1025，空气交换孔1025用于使移动终端10的壳体101外部的空气与空气腔1023内部的空气进行交换。
可选地，空气腔1023通过空气交换孔1025连接到移动终端10外部，在喇叭音腔1021内部的空气压缩触发喇叭音腔1021内部的空气通过倒相孔1026传输至热源上的空气腔1023，或者在喇叭音腔1021内部的空气被扩充时，空气腔1023通过空气交换孔1025与移动终端10外部的空气进行对流，对热源与空气腔1023之间通过导热金属热交换后的热量进行散热。即喇叭音腔1021正常工作时，通过空气交换孔1025进行降温，不需要进行任何处理，温度已经过高，也只能通过其它方式降温了；如果喇叭音腔1021没有工作，当温度传感器检测到热源温度达到了设定值时，控制器103可以通过音频功放输出低频的信号(人耳无法听到的频率)控制喇叭振膜振动，实现空气交换进行降温)。
可选地，在本实用新型实施例中，喇叭音腔1021的容积可以设计为远大于空气腔1023的容积，在喇叭音腔1021的容积远大于空气腔1023的容积时，在振膜1022的微弱振动而导致的喇叭音腔1021内的空气压强的变化，都会带来散热装置内部空气对流，散热装置对喇叭音腔1021内的空气对流有明显的放大作用，喇叭空腔将空气对流传递至热源上的空气腔1023后，空气腔1023通过空气交换孔1025和移动终端10外部的空气交换将比喇叭音腔1021内部更为剧烈，空气腔1023内部的空气对流从而实现移动终端10内外的热交换，散热效果明显。
可选地，一些实施例中，参见图2，该移动终端10中的散热模块102还包括：
设置在喇叭音腔1021上的倒相孔1026，通过倒相孔1026将空气腔1023 内部的空气抽入至喇叭音腔1021，以及，通过倒相孔1026将喇叭音腔1021内部的空气输出至空气腔1023，即喇叭音腔1021通过倒相孔1026与导气通路1024连通。
可选地，倒相孔1026可以设置在喇叭音腔1021上振膜1022的对端，在本实用新型的实施例中，喇叭音腔1021内部的空气压缩或者扩充时，通过倒相孔1026传输至热源上部的空气腔1023。
可选地，参见图3，图3为本实用新型实施例中导气通路内部的空气对流示意图，其中，包括喇叭音腔31、导气通路32，以及倒相孔33，图3中的箭头(包括向上的箭头和向下的箭头)用于标识空气对流的方向，参见喇叭音腔31内部向上的箭头311和向下的箭头312，以及导气通路32内部向上的箭头321和向下的箭头322，当喇叭音腔内部的空气压缩时，喇叭音腔31内部的空气的压强大于导气通路32内部的空气的压强，触发喇叭音腔31内部的空气通过倒相孔33向导气通路32流动(参见喇叭音腔31和导气通路32的向上的箭头)，当喇叭音腔内部的空气扩张时，喇叭音腔31内部的空气的压强小于导气通路32内部的空气的压强，触发导气通路32内部的空气通过倒相孔33向喇叭音腔31流动(参见喇叭音腔31和导气通路32的向下的箭头)。
可选地，一些实施例中，参见图2，该移动终端10还包括：
与热源相连的温度传感器104，温度传感器104用于检测移动终端10中热源的温度，得到当前温度值。
例如，移动终端10中的温度传感器104检测CPU的当前温度得到当前温度值，并将当前温度值发送至控制器103，由控制器103将当前温度值与预设温度阈值做比对，判断当前温度值是否过高，在当前温度值大于预设温度阈值时触发散热模块102进行散热。其中，散热过程可以如下：例如，CPU通过温度传感器104检测出温度太高，高于预设温度阈值，然后启动控制器103驱动喇叭振膜1022发生振动，通过导气通路1024使得CPU上部空气腔1023中的空气产生空气对流，空气腔1023内部的空气通过空气交换孔1025与移动终端10外部的空气对流，起到降温的作用，当用户在使用耳机听音乐时，控制器103可以启动喇叭，控制振膜1022振动，使得喇叭输出人耳无法 听到的信号(例如，让喇叭工作在规律的低频10Hz正弦波震荡模式)，触发喇叭上的振膜1022发生振动，起到给CPU进行降温的作用。
可选地，本实用新型实施例中的散热模块102也可以设置在穿戴设备中，在穿戴设备中可以用整个穿戴设备壳体101内部替换喇叭音腔1021，其他组件的设计可以参考本实用新型实施例，也可以对穿戴设备起到散热的作用，本实用新型实施例对此不作限制。
本实施例中，通过散热模块在移动终端的当前温度值大于预设温度阈值时，对移动终端进行散热，其中，由设置在喇叭音腔上的振膜在振动时压缩/扩充喇叭音腔内部的空气，能够使设置在移动终端的热源上的空气腔与喇叭音腔之间产生对流的空气以对热源进行散热，有效提升移动终端的散热效果，提升用户的使用体验。
