本发明的目的在于提供一种扬声器装置,旨在解决单体侧面打胶时不能完全填充单体侧面与盖板之间的间隙,最终导致扬声器装置防水失效的技术问题。
本发明的技术方案如下:一种扬声器装置,包括上盖、下盖和发声单体,所述上盖和所述下盖固定连接并形成一容纳腔,所述发声单体安装在所述容纳腔内,所述上盖开设有出音口且所述上盖往所述发声单体方向延伸出一支撑梁,所述支撑梁包括相邻的第一表面和第二表面,所述发声单体包括靠近上盖的第一端面、以及靠近所述出音口并与所述第一端面相邻的第二端面,所述第一表面与所述第一端面相对,并通过在这两者之间填充第一胶粘剂进行胶合密封以形成第一道防水结构,所述第二表面与所述第二端面相对,所述第一表面与所述第二表面的连接处往远离所述发声单体方向凹陷形成一储气槽,在所述第二表面与所述第二端面之间通过填充第二胶粘剂且所述第二胶粘剂渗流进所述储气槽中以进行胶合密封以形成第二道防水结构时被封堵的空气存储在所述储气槽中。
进一步地,所述第一表面与所述第二表面互相垂直。
更进一步地,所述第一表面与所述第二表面的连接处,朝垂直于所述第一表面方向内凹形成所述储气槽。
更进一步地,所述储气槽为方形槽。
