I'm new to this forum, even though I've been looking at all the threads I could for some time now.
To make it short : I'm in the process of designing my perfect headphones. Everything would be custom machined. I'm not saying that I'll definitely do it, but I may have the opportunity to do so in a few months, so I'm starting to model the parts, design the electronics, etc...
I'm here to get your feedback and advices on some aspects that are a bit obscure to me. I'm not a pure audiophile, but I can make the difference between some cheapo headphones and mid-range ones. I currently own a Koss Porta-Pro and a Sony MDR-V500, but I find some defects in both and I'd like to make my own, just for the sake of it :)
Here are the features that I'm planning on getting:
- Over-the-ear leather cushion
- 40mm Sawafuji SZ-2T drivers
- Noise cancellation
- iPhone/iPod remote with mic (I'd get an Apple cheap headphone and just keep the remote/mic part)
- Volume and noise cancellation adjustment knobs on the headphones
- Made out of aluminum + anodization and chroming (a first prototype might be made of wood to test design)
Everything will be open source, I'll share the design files with anyone when they'll be finished.
I'm still working on the headband, articulations and electronics. The potentiometer used is temporary, it was just to test the mechanical design of the knob. Same thing with the noise cancellation mic.
Finally, here are my questions :
- Do you have any idea about how I can design the sound chamber to get the most of the SFI drivers ? Maybe some acoustic design software, or books that I can compulse ?
- Will the ouput from an iPod or iPhone be enough for the SFI drivers or do I need to use an amp ?
- Where can I find infos on a small noise cancellation circuit that could be used ?
Sorry for the long post and I hope I'm not bothering you with my newbie questions :)
