My DIY electrostatic headphones - Page 100

post #1486 of 1634
Thread Starter 

After spending more than 10 hours with the phones, I'm glad to say that the phones are stable with 0.5 mm spacers.  And they certainly sound very good with my KGSSHV.

 

 

Here are the details of my build.

 

1.  The active area is 120 mm x 76 mm. 

2.  The perforated holes are 2 mm with the exception of the large 6 mm holes in the middle

3.  The spacer thickness is 0.5 mm.

4.  The diaphragm is 3 micron.

I can literally call the Float v2 ear-speakers because it looks like 2 mini speakers on the ears :D

Let me show you a technic I use to clean small dust on my stators.  :wink_face:

 

 

As you peel out the adhesive tape,  the dust go off with it.

I'm late to the party but look forward to reading all 100 pages in this thread.

 

Truly amazing work and such generosity to share with everyone!  

 

Perhaps this has already been discussed, but I wonder if anyone has found sources for the materials needed to make the 'phones and a good CNC service.

 

Many thanks to Wachara C and all who have posted tips and techniques,

Damn, it would be a big favor to everyone having this thread indexed.

Wachara is graciously sending me a present which I will examine and turn

into some machine code and then some full NC made stator panels and as many

of the rest of the parts as I can make.

 

This was the result of a great idea by wachara.

So when I said that I would never ever build electrostatic headphones...

I lied.

 

And the equipment I have is capable of making stators out of glass and

I have a vacuum system capable of coating them, so this should be a

whole bunch of fun.

 

When you go to sleep and dream in G code, you know you are in trouble.

I like the sound of that! Why would one make stators out of glass, though?

 

Anyway will stay tuned :)

the sennheiser he90 (orpheus) had glass stators

ross walker gave me a lot of info years ago on how
quad did their tensioning. And i have some other
confidential info on diaphram manufacture that
should help

You just have to wonder if some magic will happen here...

I tested the Float style headphones for a few hours yesterday, and everything is fine.  They are my gift to Kevin for his kind generosity and contribution to the DIY community.

 

Please don't laugh at my headphones though.  :wink_face:  They sound good, but they look kind of ..... :duggfloat:

Let me know if you need help drawing stuff up.  I've done a number of different stator designs and accompanying housings.  Probably best to decide which pad you want to build around first.

I feel that the Float style headphones are really good and easy to DIY.  For me, the most difficult parts to make are the ear pads and headband.  If you follow how I make the Float style headphones, you'll see that I use welding rods to make the arc of the headband, a piece of leather for the head pad, and foam covers with cloth as ear pads.  

 

I will post a detail drawing soon (I'm still learning to use CAD).
