Description

技术领域
本发明主要涉及一种振动装置， 尤其是指一种通过增加一悬边来替代弹波 功能， 从而达到改变其电磁振动装置厚度的一种超薄电磁振动装置及其制作方 法。
背景技术
众所周知， 电磁振动装置一般常见的就是扬声器， 而扬声器俗称 "喇叭" ， 它是一种将电能转换为声能的电声器件。 传统电磁振动装置的制作工艺歩骤包 括粘着 τ铁或 U铁、 粘着盆架和磁回， 上端子、 放弹波、 插音圈、 放振动片悬 边等程序；首先要把所需的材料准备好，从下到上，从里到外进行手工制作； 其 中， 弹波又叫定心支片， 是纸盆电磁振动装置振动***中的又一个主要元件， 它是由棉布、 绢和玻璃布等材料浸渍酚醛树脂后热压制成的波纹形圆环， 它的 主要作用：
( 1) 保持音圈在磁缝隙中的正确位置， 要求它的轴向顺性大， 使音圈能在 磁缝隙中垂直振动， 径向则要求它们能可靠地限制音圈的左右移动， 使音圈不 与华司及 τ铁接触；
(2) 弹波这个支撑件提供给电磁振动装置一个恢复力， 并影响电磁振动装 置机械 Q值即阻尼特性；
(3) 弹波、 纸盆和音圈悬挂***共同决定电磁振动装置的谐振频率和自然 共振频率；
(4) 电磁振动装置弹波起着缓冲器和机械限幅器的作用；
基于弹波的上述作用， 在传统的电磁振动装置中， 弹波的内环与音圈相连 接固定， 其外环面需要与电磁振动装置的基架相连接固定， 因此， 对电磁振动 装置的薄度形成一定的限制。
然而， 随着社会的发展， 人们生活水平的不断提高， 对液晶电视、 笔记本 电脑、 手机等电子产品的要求薄的同时， 更注重于这些电子产品的音质； 而普 通电磁振动装置运用于这些电子产品中由于受弹波的影响而限制了电磁振动装 置的厚度， 因为弹波与悬边的使用为了使电磁振动装置的音圈跟振动片均衡冲 程， 而传统的电磁振动装置， 弹波的内连接面通过打胶水的方式固设于音圈的 中央位置， 其外连接面则也是通过打胶水的方式固设于该电磁振动装置的基架 上； 这样一来， 对于音圈的长度及基架的厚度受到了弹波的限制； 进一歩， 对 电磁振动装置的厚度形成限制， 达不到这些电子产品对电磁振动装置的要求； 同时， 时间一长， 传统电磁振动装置的弹波与音圈上的胶水会出现老化， 甚至 脱胶的现象， 而导致电磁振动装置音质产生变化或使整个电磁振动装置报废。
