Designed in response to the Idesign Challenge.
This is designed for use with the iPhone 7.
This is a passive amplifier. Place the phone in the mouth and the sound is through the cone to the top of the head.
I liked the idea of creating a ceramic accessory for the challenge. It was a good opportunity to learn more about the design specs for the porcelain material.
It's an experimental accessory. I'm not too sure how well it will really amplify sound. It'll look nice trying though.
