Magnetic paper ribbon

[ABJensen]

Made another magnetic ribbon. 150cm long 5 cm wide, 6.5 ohm.
Measurement distance 1 meter.
Magnets N-S-N

Looks good from here. I will have to try a project like that one day.
Very interesting.

 

[ABJensen]

And nerfield measurement (5cm)

 

[ABJensen]

2nd-3nd-4nd distortion. How low could this go with steep crossover ?.

Playing fullrange. You can hear the dipole dip at the side.

Looks like you're having fun with these ribbons. How does it sound?

Measurement of AE dipole18 distance 1 meter.

Minimalistic . crossover 24db 300hz.

Ihave never seen a ribbon design like this before.A sort of planar/ribbon,but no suspension?Are you willing to share more informations?
Good luck.

There is felt in on the sides and the yarn in the Middle of the magnets.
the ribbon is ligth magnetic from nano iron in the glue. I have a link to
the nano iron in the 0.6my ribbon tread. By the way the magnetic ribbon
was invented by Johnny Sorensen a danish reviewer some 25 years ago.

using studio recording 'tape'

but a bit heavy, and not sure it worked that well at all

actually, I dont see the point of a magnetic diaphragm
on the contrary


thumbs up for your magnet system )

I see it now.Active membrame is app.30mm.I thought it was app 50mm.
Still i think it´s a new way of suspension. The one from Jonny vas fixed at the ends as usual or what?
Yours must be a plannar ?

Keep up your work.

Well it sounds better with nano iron. More relaxst then with out.
maby because it is much ligther then the recording tape.

it dont need to be magnetic the make the suspension just bend the magneticsystem.

New W shaped ribbon

 

[ABJensen]

Measurement 20cm and 1 meter.

 

[ABJensen]

Nearfield 2cm

 

[ABJensen]

Non calibretet mic. 1.5 meter.

 

[WrineX]

i still wonder how these work, it is hard to see.

 

[ABJensen]

Do this help ?.
