Keychain Phone Amp

thingiverse

Sometimes a bit more sound is just what you need. This tiny amp is the perfect accessory, small enough to attach to your keychain but powerful enough to boost the sound from most phones with a downward-facing speaker. I've tested it on an iPhone 6s and a Galaxy S7, among others, and people tell me it makes a big difference in the audio quality, directing the sound right towards you. If you decide to print this out, please let me know if it fits your phone model and share with me what you think of it! I'd love to see what you're working on. Don't forget to show off your creations! Thanks for taking a look, -Rob
