About this model

This project is a passive sound amplifier designed for an IPhone 6 or 6S. The IPhone can easily slide into the top and has room to still use the home button and connect the phone to a charger. In addition, the position of the horn can be adjusted up and down with the adjustment bar on the back. Some of the parts may be a bit difficult to print and clean the support material out of, however the finished product works very well and amplifies the sound by up to 20 decibels. While the phone holder is currently designed for only a only an IPhone 6/6S, the holder are easily swappable with an allen key and could be designed to accommodate other phones depending on their speaker placement.
