I've been a bit busy with this ribbon mic build. It looks nice but...
does any one have any suggested materials that are readily available to make ribbons for ribbon mics?
I have read abour sign makers metal leaf
and I am looking into some candy wrapping foil that might be thin enough?
what is my goal ? about 3 microns?
Also: curious about frequecy response and how ribbon length and width affect frequency response?
out of coincidence:
my lenght and width are almost exactly the same as my RCA 74b
RCA 2" x 1/8"
MINE 1 7/8" x 1/8"
AND actually because my ribbon mounting unit extends a tiny bit past the magnet structure the ribbon length might be 2" in mine also.
BTW: the only problem that I might have in my design concerns air flow/air pressure/sound wave flow to the back of the ribbon.
the RCA 74 has a lot of air space at the back of the ribbon
Mine has a column of air 3/16" x 1 7/8" x 1"
open at the back and the top of the magnet structure.( the bottom is the mount and therefore it's blocked and the front has the ribbon)
i have seen other design where the air flow was much tighter than my 74 so I am thinking I will be OK....we'll see
I'll post some pics in another post later. I think it will be a good looking mic when it's done.
anyway
looking forward to your responses.
thanks
