A (Low) Tech Perspective

Functional 3D Collage

A collage from found stuff that does things and sounds neat.

This is a home-brew, low-tech iPhone amp made of PVC pipe and an old bike horn. It adds a little oomph, without powered amplification. It works well, tho it amplifies some frequencies better than others (like vocals).

The bike horn (with it's noise maker removed) had just the right amount of threading on the end to screw into the soft plastic hole, and be flush with the inside of the PVC. It sits directly in front of the tiny mono speaker. Leaving the ends of the pipe open allows for a more expansive sound and lets more treble escape. The weight of the horn keeps the phone from tipping back.

I love that this re-purposes something that has been sitting around my house as a pretty object (the horn, not the iPhone). It has real functional purpose too, if we want to listen to a little music while sitting outside with a cup of coffee, for example.
