full range planar headphones using neodynium magnets

JAMESBOS · 30th January 2013, 09:07 AM

Have started 2 designs using small neo magnets, using the frames of cheap headphones that I have dis-assembled. I am still finalizing the layout of each. The magnets differ in length and thickness. When I have finished the different designs in the same headphone carcass, I will see which is the best. I have another cheap headphone carcass, which I will use for the final design. I just need the inspiration to finish them. Seem to find it difficult to be inspired to finish, seem to prefer bigger planars. It's all in the mind, which little bit is left in there.

I seem to have lost interest in the headphones at the moment! But these pictures should keep you interested, hopefully.Am rebuilding my 4' x 2' frp at the moment not happy with the resonance.

Have finally built 1 half of my design, it does work, but low volume made it 29 ohms but I will reduce that to 6 ohms or thereabouts. Made it up as I went along very fiddly at this size the other side (right) will be easier to wire up only 2 cable join up.Must get organised, and write more things down correctly so I don't forget what I have done and how!!
