A victrola style passive amplifier for a cell phone. I'm getting an 11db increase in volume from across the room, more bass and a bit of reverb, all completely unpowered.
• Cone is made from 2 file folders joined with CA glue, and coated with truck bed liner
• Tube is a 2" p-trap with a 2" thread adapter and a 3in flush fit cap, painted with hammer texture paint and then metallic oil-rubbeb bronze
• Mounting bracket is 5/8" aluminum flat stock
• The back plate and phone slot are just from some scrap 2"x10" pine I had lying around.
P.S. I apologize for the dizzying painting sections. Lesson learned I guess. holding camera + 20x speed = obnoxious
