The goal for this tweeter series was to create a transducer that has a frequency response that is flat to above 20K, and where the distortion is far lower than normal and more friendly to the ear. The tweeters represent a unique approach to tweeter design that has resulted in unrivaled performance, as well as in several patents (dual concentric diaphragm, wave-guide center plug).

这个引用,我猜想是VIFA自己的吧.足够是权威的解释了.
我是六,七年前听过,但是并没和其它同类型高音单元作过认真的对比,抱歉.
初步判断:
是个好单元,有VIFA专利保护,环状振膜和中间那个相位塞是有道理的.
没细想,或者说,没条件去仔细研究了,中间那个相位塞究竟有什么作用?
我记得它的高度大约是10MM(?),
那么它能对多高频率的声波起作用?
如果10MM是四分之一波长的话,全波长就是40MM,即4CM,
那就相当于9500HZ.
那是能在声频域的高端起到作用了.
---------
以上是我的拍脑袋的随想,有心人可以作些像样的测试和分析的了.
以前在某厂时开发部抄了个板放在网站上,结果就收到了律师信,后来不敢搞了,听说VIFA开发时也是偶然拿一个针插到球顶高音上想到的?

这段英文的含义大致是这个高音扬声器的目标是达到平坦的频率响并超过20KHZ,失真比普通的高音扬声器要低,听感完美.这个高音扬声器是一个独特的设计方法,结果显示是高性能的.其中的几个专利是(双重的同中心振膜,波浪式的中心连接).
因为没见过具体的产品,所以对其中的专利内容描述不是很准确.
谢杨老师找寻资料,让我一睹该高音的风彩,已心满意足,看上去就知是个好东东.谢欧阳版主!
日本DENON的一款音箱上的高音也用了同类型的设计,好象声扬也有同类的膜片
很多音膜厂家都有类似音膜,配置合适的话可以到30-40KHZ,我们也曾有做过,专利应该只是那个相位塞吧,当时模都开好了,才知有专利,只有重开!
