底板24、铁芯25、电磁线圈26、粘磁27和铜圈28均位于强室内并充盈整个腔室。接合后上盖1和下盖2整体的几何形状呈立方体状,且高度为2mm。这样可以使得该元件能够形成一个完整的密闭结构,通过上盖1和下盖2相互接合形成的腔室包裹住所有的元器件,同时,整体形成一个3mm*3mm*2mm的立方体结构,足够微小,能够满足大部分更精密更小的电子设备的需要。进一步地,上盖1和下盖2均采用金属材质,并且在上盖1和下盖2接合后再下盖2的边缘固定端打胶,进一步起到密封作用。同时,设置在铜圈28内、铁芯25上方的振动膜片29能够提高蜂鸣器的声压,在对电磁式蜂鸣器粘接和贴片时,振动膜片29还能够防止密封胶和助焊剂通过上盖1和下盖2之间的缝隙渗入到蜂鸣器的内部,有效保证了蜂鸣器的发声效果。上容纳腔11和下容纳腔21均呈圆柱体状,底板24呈圆形,上容纳腔11、下容纳腔21、底板24、铁芯25和电磁线圈26、粘磁27、铜圈28和振动膜片29均与上盖1和下盖2同轴。这样可以使得蜂鸣器整体的稳定性更高,结构更加稳定,从而延长使用寿命。下盖2的下出口端面上还均匀设置有若干向上延伸的固定部3,上盖1嵌合在若干固定部3内,这样可以使得上盖1与下盖2之间的密封更加牢固。 崇明区ABBAD16系列蜂鸣器性价比
