I wonder how small the magnet can be while still getting acceptable quality and volume. I imagine the smaller a magnet, the lower the power required to drive it, and less heat produced (and easier to install…) We don’t need to broadcast the audio to the world, just your skull.

How did you make it
I’m using a motor driver (L298N) to control the flexAR, and the arduino tone library for sound generation. I can hook you up with a pinout and some starter code if you’d like.
