  This is in reference to a little-known speaker design named the Heil (sp?)
Air-Motion Transformer. For the duration of it's brief career as a marketed
product, it advertised "Sound clear as Light", in addition to it's high
quality, it is up to 25 times more energy efficient than your standard
speaker. I have posession of one working model and a partial model of a
slightly different design. It's rather clever design is hard enough to
describe in person, so I won't even make the attempt here unless someone is
really dying to hear about it. If there is anyone out there who has any
knowledge about this device, I would be greatly pleased to recieve some help
with a few questions I have about it.
   It's clear that a strong magnetic field is involved. In one of the
model's I have, two large magnets are located about an inch and a half BELOW
the actual mechanism. How is this useful? In what way exactly is the
magnetic field used? Why must it be so large? If you've seen this particular
model, you've seen a strangly shaped piece of aluminum(?shiny metal) located
directly between the two large magnets and extending to almost touch the
sounding mechanism.. What is that?!
   Any further information on the Heil (sp?) Air-Motion transformer would be
greatly appreciated! At the moment I don't know all that I don't know..
Please send any replies to CHI@vms2.macc.wisc.edu, because as far as I know, I
am only subscribed to Phys-l, phys-stu, and physhare and I am afraid I might
miss postings on other lists. If you are subscribed to the above mentioned list
and the people won't reject to it, I will read it there too if you post it.


Looking forward to any information or discussion.
