Phone amplifier using parabolic focal point

thingiverse

I'm sharing a design that significantly boosts the sound coming from your phone's bottom speaker. The truth is, this design targets the sound emitted by the phone by placing the speaker port directly at the focal point of an extremely precise parabolic curve, much like a flashlight concentrates light in one direction. You'll be amazed at how effectively it focuses the sound in one direction! This design also features a channel to enable you to charge your phone while using it - talk about convenience! Right now, I've created these models for several sizes of iPhones and cases, but feel free to message me, and I'll modify them to suit your specific phone/case combination.
