3D Printing and Speaker Design

From: andrew cooke <andrew@...>

Date: Wed, 11 Mar 2015 08:05:27 -0300

I was brainstorming what I could do in my spare time if I quite work.  3D
printing seems to be more and more popular, and I've been toying with the idea
of writing GPU code to model air pressure / flow, so why not combine the two?

The idea is to model some complex shape (selected using, say, genetic
algorithms) that gives an optimal response when used as a speaker housing.
The hope is that an arbitrary shape would allow exact tuning to match the
speaker, giving good response in a small package.

3D printing should allow "arbitrary" shapes to be developed.  Size limitations
mean that it would be restricted to smaller speakers for now, but that might
change.
