Hi all. I am an electronics enthusiast, and I love taking apart discarded
radios and TVs to tinker around. I have come across, among other things,
something in particular about speakers that seems to stick in my mind for
some reason.
Most, if not 99% of all the speaker cones I have seen, consist of a center
magnet with four spokes extending outward toward the frame in a + shape.
However, in my adventures I have come across, on very rare occasions, some
speakers with only THREE spokes. These are usually small ones, about 2 to 4
inches in diameter. I have seen larger ones with as many as five or six
spokes. I have even come across one with only two spokes, and still another
type with not spokes, but about a dozen circular holes around the magnet.
I was wondring if anyone else here is familiar with what I consider to be
unique and unusual speaker frame designs? Also, while I can see four spokes
as being a good design, I wonder why it is more predominant than say, the
three-spoked frame, which would use less material to fabricate?
Another thing I would like to point out is where the magnet is housed. Most
of the speakers I come across have a drum-shaped housing with the magnet
concealed. I have come across a few with a square metal frame with the
magnet exposed (cheaper to make I presume).
Just thought I would share this with the group. I hope you at least find it
interesting as I did.
