Iphone 7 Amplifier case

Have you ever played music out of your phone and it just wasn't loud enough? You try to put your phone in a cup to amplify the sound?. Now there is no need for the cup. The case itself is an amplifier. All the volume enters through the speaker tunnel and the sound waves travel all the way to the exit. While the sound waves reach toward the exit, the waves start to bounce around and get longer which creates louder sound. The case is also comfortable to hold with its rounded edges, and just the right size to fit in your pocket.My instructor is Colin DennnyPleasant Grove High School
