DIY Planar headphone by using tweeter

oneday, I found planar headphone and planar tweeter have same operation method.
It gave me inspiration and convince me that can use to headphone.
So, I am searching some planar tweeter in taobao.
It's price is only 20~ 35$ for each unit, I think this price is very cheap.
 
 
specification
 
unit : hivi rt1.3
measurement system : panasonic wm61a (I using BMF's circuit)

frequency response

my soundcard is ALC892 so I couldn't mesure it exactly under 150Hz and over 17khz.
I can find little difference comapre left with right because diaghram was stabbed when I assembled it.
 
 
total is about 170$ because I almost used 70$ to housing
if you use plastic housing, you can make it about 100~120$
 
I'm not good at English so if you find out some error in writing, please point out it

Excellent work!
 
I'm guessing this is the planar tweeter that you used: http://www.parts-express.com/hivi-rt13-planar-isodynamic-tweeter--297-412
 
Do you think a similar HiVi tweeter (that isn't out of production) would work in your design as well? Perhaps one of these:http://www.parts-express.com/Search.aspx?keyword=hivi%20ribbon&sitesearch=true

yes that is what I use.
 
other hivi tweeter's diaphragm was too small.
 
planar tweeter have nice straightness.
 
So if you use other hivi's tweeter your headphone's frequency response is dramatically chaged by position of tweeter
 
I recommended this product
http://www.madisoundspeakerstore.com/ribbon-tweeters/hi-vi-rt1.3we-isodynamic-tweeter/
 
it is almost same unit compare with rt1.3.
 
fianally if you want to use it to headphone you need some modification
 
I will post it as soon as possible

Very interesting, wished I could hear those DIY headphones. Always interesting what people can make themselves. 

Didn't realize it was on Madisound. Thanks for the heads up! I might start playing around with something like this in the near future.

Vary nice, do you have other orthodynamic (aka planer magnetic) headphones to compare the sound with? This reminds me of the spi tweeter ortho mods from a couple years ago.

thank you for your compliment.
unfortunately, I don't have any other headphone. This is my first headphone.

Nice!
Where did you get this headband?
