Description

一种扬声器装置 技术领域
本发明涉及电声转换技术领域，尤其涉及一种扬声器装置。
 背景技术
随着移动互联网时代的到来，智能移动设备的数量不断上升，而用于播放声音的扬声器装置也被大量应用到现在的智能移动设备中。
然而，现有的扬声器装置存在防水性不强的不足之处。如附图1和附图2所示，为现有的扬声器装置，该扬声器装置包括上盖1、与所述上盖1组配形成收容空间的下盖2、收容于所述收容空间内的发声单体3，上盖1在靠近出音孔4的位置处设置有支撑梁11，所述单体3外形与上盖1配合定位。单体3侧面打胶时，因空气滞留在打胶槽的底面，不能完全填充单体3侧面与盖板1之间的间隙，这样，单体的侧面就不能起到防水的功能，当单体音膜面与盖板间胶水失效时，水会从单体侧面流入经单体内部而进入扬声器装置的后腔，损坏扬声器装置。
 技术问题
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。
 技术解决方案
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。
进一步地，所述第一胶粘剂和所述第二胶粘剂均为胶水。
进一步地，所述上盖与所述发声单体之间还设置有定位结构。
更进一步地，所述定位结构包括定位柱和定位槽，所述定位柱和所述定位槽可互换的设置在所述上盖和所述发声单体上，所述定位柱和所述定位槽插接配合。
 有益效果
本发明通过增设一个储气槽，用于储存未及时排出的空气，这样，在单体进行侧面打胶时，胶水能很好的将单体与支撑梁之间的间隙填充满，从而构筑形成第二道防水屏障，在单体音膜面与盖板间正面的第一道防水屏障失效时，第二道防水结构的存在也可以起到防水效果，从而大大提高了扬声器装置的防水良率和防水可靠性。
