Hi,
I need to build an oscilating screen of about a4 size. The screen needs to be made from 1mm thick acrylic and be flat. It needs to oscilate up and down a total distance of 4cm (2cm up then 2 cm down) and do this a total of 30 times per sec , so 15 ups and 15 downs.
I'd like the motion to be as linear as possible , which due to inertia, and momentum I undestand is impossible to achieve totally, but as close to linear would be ideal.
Some ideas I have had.
1) some kind of magnetic coil, as if the screen were attatched to a large speaker through which a traiangular 16hz sounds wave was being played.
2) Some kind of cam
3) A compressed air oscilating valve of some kind.
Does anybody have any better ideas?
Thanks
