So, I need to make a wireless wooden speaker (no Bluetooth or anything, you just put the phone in and it makes it somewhat louder) for my phone (white iPhone 4 without a case if you wanted to get an idea of the dimensions and aesthetics). My design sketch as of now is a cube measuring roughly 6in by 6in by 6in (obviously, because it's a cube). On the top side of this cube, the phone will sit in an insert area (the sound comes out of the bottom of my phone so it will rest as though it were a landline or home phone). Then the part that the sound will actually exit the speaker will be on the front side of the cube. What shapes inside the cube would make the sound amplified? For instance, would spiraling the sound around miniature tunnels like you do with copper wire amplify the sound? *NOTE* The cube is going to made out of layers (so if you look closely you would be able to see that it is just layered square wood to create a cube of wood), I haven't decided on the wood yet but was thinking of either plywood, MDF, or something dark. But I'm open for suggestions!
