A Study of DMLs as a Full Range Speaker

[SapphireSloth]

Oh, I selected the magnet block in 2 of those designs so that must not be correct in the middle and right ones. Idk how to model & measure this the right way when the coil is overlapping the magnet. Or maybe that is right, idk. Help?

For interest, I recently measured the throw of a Dayton DAEX25FHE-4 exciter at 1.1mm in and 1.4mm out.
A Dayton 3.5" TEBM65C20F BMR driver measured 2.5mm in, 2.9mm out.
So if it could be controlled, and the panel be able to bend sufficiently, the BMR driver should provide more base than the standard exciter...Yet to be tried

Hello Eucy,
Is it the maximum mechanical stroke on each direction or is it under the same amount of current?

a simple but reliable way to know what sort of linear travel is available is to expect about 1/3 of the top plate thickness and that is going to be pretty much the linear peak to peak travel of a speaker motor.

Christian, they were the "clack to clack" max mechanical strokes under DC battery hookup
