I've tried many sound deflectors for my iPad mini, all had flaws, one of which is loosing much of the bass response and stereo separation the iPad's little speakers have. I decided to design my own. It turns out the angle and thickness of the deflecting surface matters a lot. After 7 prototypes I share with you my final results:
IMPORTANT NOTE: it's designed to fit over the iPad mini with the Smart Case. If you don't have the case I won't fit.
