[0035] 作为本实施例的一较佳实施方案, 透气网板 121的厚度为 0.05mm, 第一粘接层 122的厚度为 0.05mm, 第二粘接层 130的厚度为 0.15mm, 这样, 便于透气网板 12 1、 第一粘接层 122、 第二粘接层 130的制造成型。
[0036] 本实施例中, 透气网板 121的厚度和第一粘接层 122的厚度之和小于第二粘接层 130的厚度, 防尘网 120的总厚度为第二粘接层 130的厚度, 其在安装时, 省去了 透气网板 121和第一粘接层 122的安装空间 (本实施例中省去了 0.2mm的安装空间 '、 。
[0037] 当然了, 具体应用中, 作为本实施例的一个替代实施方案, 也可将透气网板 12 1的厚度和第一粘接层 122的厚度之和设置为等于第二粘接层 130的厚度 (例如将 第一粘接层 122的厚度设置为 0.1mm, 将透气网板 121的厚度设置为 0.05mm, 将 第二粘接层 130的厚度设置为 0.15mm) , 其在安装时, 也可省去透气网板 121和 第一粘接层 122的安装空间。
[0038] 或者, 作为本实施例的另一个替代实施方案, 也可将透气网板 121的厚度和第 一粘接层 122的厚度之和设置为大于第二粘接层 130的厚度 (例如将第一粘接层 1 22的厚度设置为 0.15mm, 将透气网板 121的厚度设置为 0.05mm, 将第二粘接层 1 30的厚度设置为 0.15mm) , 其在安装时, 可省去第二粘接层 130的安装空间。
[0039] 具体地, 请参阅图 3、 图 4和图 6, 扬声器箱主体 110包括壳体 10、 发声单体 112 和柔性电路板 114 (FPC) , 出声孔 101设于壳体 10上, 发声单体 112固定于壳体 1 0上并与出声孔 101对应。 发声单体 112和防尘网 120分别安装于壳体 10的两相对 侧。 柔性电路板 114安装于发声单体 112的一侧部。
[0040] 优选地, 请参阅图 3和图 4, 壳体 10包括塑料支架 111和嵌设于塑料支架 111的金 属片体 113 , 塑料支架 111与金属片体 113注塑成型为一体; 发声单体 112具有振 膜 115, 金属片体 113与振膜 115正对, 出声孔 101对应贯穿金属片体 113。 [0041] 具体地, 扬声器箱主体 110还包括盖板 (图未示) , 壳体 10盖合于盖板上并与 盖板围合形成一收容腔, 发声单体 112安装于收容腔内。 发声单体 112与盖板共 同围合形成前腔, 发声单体 112、 金属片体 113与塑料支架 111共同围合形成后腔 。 前腔用于出声, 后腔用于改善扬声器箱 100的低频声学性能。 金属片体 113的 设置, 一方面可用于加强壳体 10的强度, 起到支撑作用; 另一方面可减小壳体 1 0的厚度, 从而利于获得更大的后腔, 进而利于提高扬声器箱主体 110的低音效 果; 再一方面利于提高扬声器箱 100的散热效果。
[0042] 进一步地, 本实用新型实施例还提供了一种移动终端设备, 其包括外壳 (图未 示) 和上述的扬声器箱 100。 扬声器箱 100设于外壳内, 扬声器箱 100通过第二粘 接层 130与外壳粘接固定。 本实施例提供的移动终端设备, 由于采用了上述的扬 声器箱 100, 故, 使得外壳内预留给扬声器箱 100安装的空间减小了, 从而利于 将移动终端设备的体型设计得更小。
[0043] 优选地, 移动终端设备为手机或者平板电脑或者 mp3或者 mp4或者 mp5, 手机 、 平板电脑、 mp3、 mp4、 mp5采用本实施例中扬声器箱 100的结构设计方案, 都 能将产品的体型小型化设计。
[0044] 本实施例中, 将防尘网 120分开做成两个物料, 内圈由 0.05mm的 Mesh (透气 网板 121)
和 0.05mm的普通双面胶 (第一粘接层 122) 叠压构成, 满足出声孔 101的防尘要 求; 夕卜圈贴一圈 0.15mm的环形双面胶 (第二粘接层 130) , 保证防水功能不变。 内圈的厚度为 0.1mm, 小于外圈 0.15mm防水双面胶的厚度, 不影响高度空间。 因此出声孔 101外侧高度仅需要 0.15mm的安装空间, 减小了防尘网 120的安装空 间。
[0045] 以上所述的仅是本实用新型的实施方式, 在此应当指出, 对于本领域的普通技 术人员来说, 在不脱离本实用新型创造构思的前提下, 还可以做出改进, 但这 些均属于本实用新型的保护范围。
