Once the case design was finished in Solidworks, a 3D printed ABS plastic test part was made to verify that everything fit correctly. After a few minor changes, the aluminum case was machined.

This is a good explanation of how parametric speakers work and a few interesting uses. The Soundlazer can do all these things and more.
Designing the case turned out to be as difficult as the circuit itself. A modern, “Apple” style case was the goal but with a retro feel. A classic microphone offered the inspiration for this design project. Classic Ribbon Microphone The high frequencies emitted by the Soundlazer presented some problems in the case design. […]
The SoundLazer uses very small surface mounted components There is a whole lot of technology crammed into a small space in the Soundlazer. Many of the surface mount components are size 0402 which is going to make prototyping this board a bit tricky. Time to get out the microscope and tweezers for this soldering […]
