Description

扬声器组件、便携式电子设备及扬声器组件的组装方法 【技术领域】
本发明涉及声电领域，尤其涉及一种扬声器组件、便携式电子设备及扬声器组件的组装方法。
【背景技术】
移动电子设备内通常设有扬声器，扬声器的发声单体直接固定于天线盖板上，由于移动电子设备整机散热设计，扬声器内的发声单体的音膜面通常朝向天线盖板方向，而天线盖板尺寸较大，经过注塑、激光直接成型技术后整体变形较大，天线盖板上的安装发声单体的平面和贴双面胶的平面等重要平面平整度较差，影响产品整体的防水性能，且对天线盖板滚镀时会对开设于天线盖板上的出音孔造成划伤。
因此，有必要提供一种新的扬声器解决上述技术问题。
【发明内容】
本发明的目的在于提供一种改善防水性能的扬声器组件。
本发明的技术方案如下：本发明提供一种扬声器，包括天线盖板及安装至所述天线盖板的扬声器、所述扬声器包括安装至所述天线盖板的第一壳体和盖合于所述第一壳体的背离所述天线盖板的一侧的第二壳体，所述第一壳体与所述第二壳体共同限定一收容腔，所述扬声器还包括收容于所述收容腔内的发声单体。
优选的，所述天线盖板上开设有第一安装槽，所述第一壳体安装于所述第一安装槽内。
优选的，所述第一壳体具有朝向所述发声单体的内侧和远离所述发声单体的外侧，所述第一壳体的外侧的周缘形成有第一台阶面，所述第一台阶面与所述第一安装槽的槽底面配合。
优选的，所述第一壳体的内侧形成有第二安装槽，所述发声单体嵌设 于所述第二安装槽内。
优选的，所述发声单体包括用于振动发声的振膜，所述振膜朝向所述第二安装槽的槽底设置，所述振膜与所述第一壳体间隔形成前声腔，所述第一壳体上开设有连通所述前声腔与外界的出声通道。
优选的，所述第一壳体具有第一壳体本体和自所述第一壳体本体的边缘向所述第二壳体延伸的第一侧壁，所述第一侧壁的内壁面形成有第二台阶面，所述第二壳体具有第二壳体本体和自所述第二壳体本体的边缘向所述第一壳体延伸的第二侧壁，所述第二侧壁上形成第三台阶面，所述第三台阶面与所述第二台阶面配合。
优选的，所述第三台阶面与所述第二台阶面超声波焊接。
本发明还提供一种便携式电子设备，包括如上所述的扬声器组件。
本发明还提供一种扬声器组件的组装方法，包括：
将发声单体、第一壳体及第二壳体组装形成扬声器；和
将所述扬声器安装于天线盖板上。
优选的，所述将发声单体、第一壳体及第二壳体组装形成扬声器具体包括：
将所述发声单体安装于所述第一壳体或所述第二壳体上；和
