I did some more prototyping on this design, using milled 1/16" cotton-phenolic, instead of laser-cut 1/8" plywood. I also cured the membrane onto a thin sheet of carbon with a 0,+60,-60 layup. I also switched to 1/8" (D) x 1/16" (H) magnets, instead of 1/8" (D) x 1/8" (H), because the simulations predicted the force output would be similar. The total stack is about 4mm thick. :)

The total stack is about 5mm thick, but I think could be even thinner with some redesign.
