The amplification of an audio source doesn’t always require electronics. Sometimes all you need is a well designed wooden box with the right acoustic properties. Case in point the Timbre Amplifier for your iPhone. Timbre by designer by Tyler Pratt is locally crafted from black walnut wood and is available in two finishes. The wooden amplifier provides up to 20 decibels in audio increase with no cords, no batteries, no wire. It looks nice, is well designed and provides good function with little visual intrusion.
