GGRP has discovered a brilliant way to demonstrate their sound engineering capabilities with this cardboard phonograph. For the design, an unassuming piece of corrugated cardboard acts as an envelope and unfolds into a record player. The enclosed record can be manually spun with a pencil and the vibrations travel through the needle to be amplified by the cardboard.
As if that kind of creative promotional material wasn't awesome enough, GGRP also created a vintage 1950's-style video introduction to the cardboard phonograph. The video details the simple assembly and hand-cranking technique for playing the record.
