发明实施例
具体实施方式
下面结合附图和实施方式对本实用新型作进一步说明。
请参照图1-图3，扬声器100包括具有收容腔110的壳体1以及收容于所述收容腔110内的发声单体2，所述壳体1上开设有连通所述收容腔110的通孔1211，所述通孔1211上盖设有玻璃片122。
本申请用玻璃片122替代现有技术中的钢片，避免了钢片对扬声器100周边的天线的干扰，且同时具有扩大收容腔110体积的效果。
优选所述发声单体2将所述收容腔110分隔成前腔120和后腔130，所述玻璃片122可对应所述后腔130设置，也可对应所述前腔120设置，也可以对应前腔120和后腔130均设置。
优选所述壳体1包括上盖板11和与所述上盖板11配合并围合形成所述收容腔110的下盖板12，所述发声单体2与所述上盖板11围合形成所述前腔120，所述发声单体2、所述上盖板11和所述下盖板12围合形成所述后腔130，所述下盖板12包括与所述上盖板11配合的框体121，所述通孔1211形成于所述框体121，所述玻璃片122安装于所述框体121上。
可以理解地，框体121起到较好的连接上盖板11的作用以及固定玻璃片122的作用。
优选所述通孔1211的侧壁上设置有用于与所述玻璃片122的边缘配合的凹槽1212。通过将玻璃片122的边缘嵌设于凹槽1212内，使得玻璃片122的安装更稳固。
优选所述玻璃片122的边缘与所述凹槽1212胶粘，如此，安装起来方便且固定效果较好。
