看不懂怎么回事

粗糙啊！

看了不敢买，见光死

对了    声音如何？

blue7

声音还是不错的~~~~~~~

莱卡

辐射面积大，声音还可以，有点“没特色”的特色

水晶

是真品吗？

幽雅

就这工艺?

晴风雨

技术应是在那块的板上，谁能说说是怎么弄出来的？

是在一层非常薄的Kapton材料上镀一层铝膜,再蚀刻出音圈,用钕铁硼磁体推挽驱动.

关键是有谁知道什么药水可以蚀刻掉铝膜? 还有什么材料可以保护铝膜不被这种药水蚀刻掉?

昨晚刚看过一些关于R1的文章,原来大部分人都不知R1的发声膜是利用金属印刷术"印刷"上去的.

若金属印刷那就好办了.画好线路图,找家印刷厂开个板子就行了,要多少印多少.

改天找一下印刷厂去问问印刷铝膜的具体情况,但我总觉得这应该是电镀厂干的事情.

真的想搞吗?虽然我懂的不多,但此类单元不会那么简单吧?!例如铝膜的抗氧处理,膜基材的选用(基材的选择本来就好多考虑因素),磁体结构,磁铁类型......等等,可能要三几本书厚的资料准备才行.

刚推出的时候买的，听了一个星期就放在杂物堆了。

薄膜高音，不是铝带，没有音乐味。

标准叫法应该是“薄片扬声器”，振膜是用耐高温的高分子薄膜做成的，音圈装在或印刷在高分子薄膜上，把这种印刷有音圈的高分子薄膜置于特殊形状磁体构成的磁场中，就可做成薄片扬声器。可不需要匹配变压器。在音质方面，它和带状扬声器一样，不失真的自然声音感可延伸到超高频段。

这种扬声器早就有了，怎么会有人说神秘？

壮家汉

现在太多的厂家生产了，例如银笛、T&T和不少不知名的厂家，不神秘了。

真的搞不懂,如何以物理结构类分何为铝带呢?

找到一段E文的，请高手翻译一下。
What's ribbon transducer?
The ribbon transducer is quite old as a concept, and was developed by European Acoustic Laboratories in 1928.


Fundamental physics support the ribbon as the most perfect type of transducer. A thin light metal ribbon is suspended in a powerful transverse magnetic field. The signal current passes through the current and magnetic field. The electromagnetic circuit has complete control over ribbon motion. The ribbon itself projects the sound. The ribbon serves both as voice coil and diaphragm. Every part of the ribbon is driven directly and simultaneously without any energy storage.

The ribbon transducer improves the performance of loudspeaker systems for the following reasons:

1. No sound coloring, in usable frequency range output voice always fidelity to input signal.  
2. Speed of response, start and stop in instantaneous, permit it to maintain the leading edge of musical sounds and their harmonics.  
3.  Extremely low inter-modulation and harmonic distortion
4.  Extremely low mass device.  
5. Capable of the highest efficiency known in direct radiator transducers.  
6. High rate of Young's modulus.
7. Extremely wide, flat frequency response (800Hz through 100 KHz.)
8. Flat impedance in usable frequency range that easy to design X-over.

Summary
The ribbon loudspeakers are superior to other transducers because all design factors are correct. Other high range extenders do not blend easily when added to loudspeaker systems because they add their own distortion by transient smearing, energy and non-linear response. The quality of materials used in ribbon speakers has the ability to "clean up" and "open up" not only the extreme highs, but also the middle tones without adding any distortion. The addition of a pair of ribbon loudspeakers to any quality speaker system is the most cost effective way to improve the performance of a loudspeaker system.
