如图1和图2所示，壳体1包括沿第二方向Y相对设置的用于围成容纳腔11的上盖12和底座13，上盖12设置有开口121，当上盖12与底座13连接后，散热支架3的一部分能够通过开口121伸出壳体1。其中，上盖12与底座13一体成型或可拆卸连接。当上盖12与底座13一体成型时，能够增加壳体1结构的稳固性；当上盖12与底座13可拆卸连接时，能够便于容纳腔11内部零件的安装、维修和更换。本申请对上盖12与底座13的连接方式不做特殊限定。
如图1和图2所示，散热支架3包括本体部31，本体部31的一部分安装于容纳腔11内，本体部31的另一部分延伸至所述壳体1外侧，本体部31为于壳体1外侧的一端设置有沿扬声器模组厚度方向（即沿第三方向Z）向上弯折延伸的延伸部32，延伸部32与扬声器模组外界的散热零件（图中未标示）抵接，其中，该散热零件包括但不限于终端设备的中框、外壳等，且散热零件的材质为金属或其他导热性良好的材料。此外，本体部31设置有第一冷却通道311，第一冷却通道311绕设于扬声器单体2周围，延伸部32设置有与第一冷却通道311连通的第二冷却通道321，第二冷却通道321沿第三方向Z向远离扬声器单体2的方向延伸。
在本实施例中，散热支架3内部设置有用于容纳冷却液的绕设在扬声器单体2周围的第一冷却通道311以及用于容纳冷却液的与扬声器模组外界的散热零件抵接的第二冷却通道321，扬声器单体2震动所产生的热量能够传递至散热支架3，并经由第一冷却通道311及第二冷却通道321内的冷却液传递至外界空气及散热零件，以降低扬声器单体2的温度。同时，由于延伸部32位于容纳腔11外并与散热零件抵接，使得第二冷却通道321内的冷却液的温度低于第一冷却通道311内的冷却液的温度，从而使得第二冷却通道321内的压强小于第一冷却通道311内的压强，第一冷却通道311内的高温冷却液在压强差的作用下流向第二冷却通道321，从而实现冷却液的循环流动，进而提升了散热支架3的散热效率。
具体地，如图2和图3所示，散热支架3包括可拆卸连接或固定连接的上支架33和下支架34，在本申请中，如图3和图4所示，上支架33设置有安装部334，下支架34设置有安装配合部344，安装部334与安装配合部344之间通过连接件4连接，以实现上支架33和下支架34的可拆卸连接，从而便于安装支架的安装、拆卸。其中，连接件4的种类包括但不限于螺钉、螺杆、定位柱等。
更具体地，如图4所示，上支架33包括第一本体331和第一延伸部332，下支架34包括第二本体341和第二延伸部342，第一本体331和第二本体341沿第三方向Z层叠设置，第一延伸部332和第二延伸部342沿第二方向Y层叠设置，上支架33与下支架34连接后，第一延伸部332和第二延伸部342拼接形成散热支架3的延伸部32，第一本体331和第二本体341拼接形成散热支架3的本体部31，且延伸部32相对于本体部31沿第三方向Z向上延伸，从而使得第一冷却通道311的轴线所在平面与第二冷却通道321的轴线所在平面存在预设夹角（该夹角包括但不限于90°、60°、45°等），以便于第二冷却通道321与散热零件抵接并进行热量传递，从而简化散热支架3的结构。
如图5所示，散热支架3设置有第一通孔35，该第一通孔35的至少部分位于第二冷却通道321围成的空间内，以增加第二冷却通道321与空气的接触面积，进而提升散热支架3的散热效率；同时，能够在保证散热支架3的结构强度的同时减少散热支架3加工所需要的材料，降低散热支架3的加工成本，并降低散热支架3的重量。
如图6和图7所示，上支架33设置有沿第三方向Z贯通第一本体331的安装孔333，下支架34设置有安装槽343，安装孔333与安装槽343的位置相对，且扬声器单体2的一部分伸入安装孔333并与安装槽343的底壁抵接，以简化扬声器单体2与散热支架3的连接方式，从而简化了扬声器单体2和散热支架3的结构。其中，扬声器单体2与安装槽343的底壁的连接方式包括但不限于粘接、焊接等。此外，如图7所示，安装槽343的底壁设置有第二通孔343a，所述扬声器单体2的一部分通过所述第二通孔343a裸露在所述容纳腔11内，从而增加了扬声器单体2与空气的接触面积，若散热支架3无法正常工作，扬声器单体2还能够通过容纳腔11内的空气进行散热，增加了扬声器单体2的散热途径，进而增加了扬声器模组的散热效率及散热稳定性。
此外，如图6和图7所示，上支架33的第一本体331设置有第一槽道331a，第一延伸部332设置有第二槽道332a，下支架34的第二本体341设置有第三槽道341a，第二延伸部342设置有第四槽道342a，上支架33与下支架34连接后，第一槽道331a与第三槽道341a围成第一冷却通道311，第二槽道332a与第四槽道342a围成第二冷却通道321，以便于第一冷却通道311和第二冷却通道321的加工，从而减少加工散热支架3所需要的工序，进而降低散热支架3的加工成本。
第一冷却通道311和第二冷却通道321的具体结构如图8所示（以上支架33的仰视图为例），第一冷却通道311包括：沿第一方向X相对设置的第一通道311a和第二通道311b，沿第一方向X延伸的能够连通第一通道311a与第二通道311b的第三通道311c，第一通道311a、第二通道311b和第三通道311c包围扬声器单体2；第二冷却通道321包括：沿第一方向X延伸的第四通道321a，沿第三方向Z延伸的能够连通第四通道321a与第二通道311b的第五通道321b，能够连通第一通道311a与第四通道321a的第六通道321c。其中，第六通道321c的内径尺寸小于第五通道321b的内径尺寸，使得第六通道321c内的压强大于第五通道321b内的压强，从而使得冷却液具有预设的流动轨迹，即第一通道311a——第六通道321c——第四通道321a——第五通道321b——第二通道311b——第三通道311c——第一通道311a，从而使得冷却液在散热支架3内具有稳定的流动轨迹，降低了冷却液流动方向相反而堵塞第一冷却通道311或第二冷却通道321的风险，从而提升了冷却液流动的稳定性，进而提升了散热支架3的工作稳定性。
更具体地，如图8所示，第一通道311a的一端设置有沿第一方向X向靠近第二通道311b的方向延伸的第一弯折通道311a1，第二通道311b的一端设置有沿第一方向X向靠近第一通道311a的方向延伸的第三弯折通道311b1，以增加第一冷却通道311与扬声器单体2的接触面积，从而进一步提升散热支架3的散热效率；第一通道311a还设置有沿第二方向Y弯折延伸的第二弯折通道311a2以及沿第一方向X向远离第二通道311b的方向弯折延伸的第五弯折通道311a3，第一弯折通道311a1与第六通道321c之间通过第二弯折通道311a2和第五弯折通道311a3连通，第二通道311b还设置有沿第二方向Y弯折延伸的能够连通第三弯折通道311b1与第五通道321b的第四弯折通道311b2，以便于第二冷却通道321与第一冷却通道311的连通，从而简化了第二冷却通道321与第一冷却通道311的结构，进而降低了第二冷却通道321与第一冷却通道311的加工成本。
此外，散热支架3设置有注液口36，第一冷却通道311及第二冷却通道321能够通过注液口36与外界连通，以便于向第一冷却通道311及第二冷却通道321内注入冷却液。本申请对注液口36的具体位置、形状、尺寸等均不作特殊限定，在本申请中，如图8所示，注液口36与第五弯折通道311a3连通，且位于第五弯折通道311a3远离第二弯折通道311a2的一端。
