Designing the enclosure

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.

The high frequencies emitted by the Soundlazer presented some problems in the case design.  With thirty nine emitters, a way had to be found to enclose the electronics without putting anything in front of the piezo elements that would inhibit or affect the ultrasonic signal.  At these frequencies, even a speaker grill could change the way the sound is emitted.

 

 The case and all mechanical components were designed in Solidworks

 

An adjustable stand will be made of 12 gauge steel, bent and then powder coated

 

Each component was modeled to make sure it fit properly inside the case
