Dear connoisseurs of high-quality sound,
I want to tell you the story of the creation of full-size flat magnetic headphones with orthodynamic radiators of new generation, developed by our company after a careful study of the construction of various planar radiators. After the experience gained we have a lot of interesting things to showcase to the whole world.
What are our goals:
1. Create high-quality open planar headphones.
2. The sound quality level should exceed all known DIY-projects and be approximated and be on par with the best known in the world top samples of planars.
3. Do not aim to reduce the budget and to focus on the application of advanced technologies, of the manual labor and the use of expensive, high-quality materials.

So, we begin the project from the magnetic system. In the photo you can see it is in draft form, but adhesive residue will be washed after its tests and
it will take an exemplary look.
The magnetic system fundamentally has an aluminum cassette, in which by super strong adhesive glued powerful neodymium magnets, allowing to strictly control the membrane all over the plane.
Thank you all for your attention.

Soon we plan to make headphone cups, I want to ask the forum members, what material is better to make from? From wood or aluminum? On the picture, grids made from ebonite with using of manual polishing of parts.

Here is ready to install magnetic system and three-layer membrane in the form of a sandwich made of mylar and aluminum on both sides of the film.

Hi, guys! Why silence? I need your advice!

Whats the thickness of the mylar?

 

[ericj]

Did you buy the mylar + aluminum film or manufacture it? I've considered making a diy planar magnetic using Pyralux - 35uM copper on both sides of 25uM kapton. But I'm not sure i could heat-form it like you've done your mylar.

Also, though aluminum is certainly lighter, a magnetic steel cassette would help focus the magnetic field. I believe Foster/Fostex is using steel for their modern drivers.

The thickness of mylar is nine micron.We had glue aluminum with mylar.And cassette is made of aluminum, because it is easier to work on the CNC machine than steel.

Why is this thread dead? The project seems badass!

Ikr, this project seems super cool. Wonder where the op went.

With what material is the magnetic planar driver created and does it need a crossover, right?

 

[Nanotech]

I thought that no one was interested and went into further development, IEM on Hale AMT driver

Looks great. Where did you get a driver?

 

[Nanotech]

I do everything except the magnets myself.

 

[BURNART]

Did you etch aluminium or something else?
