For fun I designed this “thing” so I can place my phone in it, and have it “amplify” the sound coming out of the built in speakers. It does work, and gives the sound a bit more depth. Fun little project. The hole for the phone is sized for my Iphone 11 with a case on it. Should be easy enough for you to modify for your phone / size.
