作为优选地实施方式，第一加强板261包括与振膜251正对的主体部263以及自主体部263边缘朝底壁215方向弯折并嵌设于壳体21的弯折部264，第二加强板262自弯折部264弯折延伸，至少部分弯折部264嵌设于支撑壁217，以便于支撑金属嵌件26。主体部263与第二加强板262均为平板状，金属嵌件26上的主体部263、弯折部264及第二加强板262一体成型，以降低扬声器箱20的生产成本。
本实施例中导热件40可以为实心的导热体，在导热件40和金属嵌件26之间可采用焊接或者胶粘将二者进行固定连接；当然，导热件40也可以为内置有冷却液的导热管，此时，在导热件40和金属嵌件26之间可采用焊接将二者进行固定连接。
本实用新型中，导热件40包括叠设于第二加强板262上的接触部41和自接触部41一侧延伸并与发热元件30相连接的连接部42，接触部41的宽度大于连接部42，以便于增大导热件40的散热性。具体地，接触部41在第二加强板262上的正投影覆盖第二加强板262表面的2/3以上。
定义导热件40的两端分别为输入端和冷凝端，本实用新型的电子产品在具体使用时，可将手机中导热件40的输入端紧贴CPU等发热元件30上，冷凝端紧贴扬声器箱20的金属嵌件26表面，热量从输入端进入，当导热件40为内置有冷却液的导热管时，输入端的冷却液受到加热蒸发，从中空的导热管穿过，在温度更低的冷凝端逐渐冷却，由蒸汽重新变成液体，再由导热管向输入端回流，不断重复这个过程，以便于将发热元件30产生的热量快速传递给金属嵌件26，金属嵌件26再将热量传导至前腔23内，利用扬声器单体25的风冷效果将导热件40中的热量快速导出到外部空气中，以达到液冷和风冷相结合的效果，其散热效率更高，能快速有效的散热。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
