所述侧壁12设有与外界连通的出声口120以及与所述容纳空间连通的贯穿孔121。
所述挡板14的两端分别抵接所述侧壁12和所述支撑壁13，且所述挡板14的高度自所述侧壁12向所述支撑壁13方向逐渐减小，进一步，为更清楚的说明本申请的内容，将两个所述挡板14分别定义为相对设置的第一挡板141和第二挡板142，所述第二挡板142包括本体部1421以及自所述本体部1421远离所述第一挡板141的一侧边缘向靠近所述下盖2方向延伸的延伸部1422，所述第一挡板141向所述第二挡板142方向的投影与所述本体部1421重合。所述导热件4自所述后腔30延伸至所述挡板14并搭接于所述挡板14，使得所述挡板14、顶壁11及导热件4共同形成与所述前声腔20连通的导声通道40。所述出声口120与所述导声通道40连通，用于将声音传导至外界。
具体的，所述导热件4包括搭接于所述挡板14的散热部41、与所述发热部件220连接的导热部42以及连接所述散热部41和所述导热部42的传热部43。
