平面振膜耳机售价高昂到底是素质高还是胆子大？ 第1页

1. 旗舰平板耳机的声音比旗舰动圈要好吗。。。

一张图顶 100 个字。

对了， 还有这个

2. 如果平板大耳素质真的很好，在技术上也较容易实现的情况下，为什么那些著名的动圈厂对平板全都无动于衷？

Orthodynamic headphone Patent (Patent # 4,389,542)

Orthodynamic headphone

Apr 23, 1981 - AKG Akustische u. Kino-Gerate

Headphone earpieces which comprise each at least one electroacoustic transducer operating on the orthodynamic principle and including a small-mass diaphragm of an extension corresponding at least to that of an average auricle, with the coupling space of each of the earpieces being designed for a minimum reflection, are equipped with an ear cushion which, with the headphone in position of use, tightly encloses the coupling space toward the outside.The disadvantages of headphone with an orthodynamically driven diaphragm which have hitherto been used only with the coupling space tightly enclosed, may be eliminated by omitting the tight enclosure of the coupling space and effecting the coupling to the ear by means of an ear cushion (1) of reticulate foam material by which the coupling space is enclosed at least laterally and which, while resting against the ear (2) or the user's head, has an acoustic frictional resistance approximately of the order of magnitude of the transformed wave impedance of air, so that the diaphragm (3) oscillation is impeded predominantly by friction and the critical damping of the low-frequency resonance (70 to 300 Hz) of the diaphragm is insured.

早在上個世紀七十年代就已出現類似技術製成的耳機。誰是全世界第一家推出場極式技術耳機的廠商呢？

YAMAHA！第一款場極式耳機的型號是？1975年發表的HP-1。不過，當年YAMAHA並不是以「Planar Magnetic」註冊其平面振膜發聲技術的專利，而是「Orthodynamic」(以前翻譯等磁式)，原因是「Planar Magnetic」早就由平面喇叭先鋒大廠Magnepan創辦人Jim Winey在1969年率先使用(Quasi Ribbon/Plannar-Magnetic Driver)，因此，Yamaha才會以Ortho(直接)-dynamic(動圈)來形容其平面振膜發聲技術。

注意：Mylar中文叫涤纶, 当然啦， 麦拉听起来高端洋气。

说白了就是用些高阻抗的平板高音头，做成了耳机。

这个需要您自己下结论。
