Product Life Cycle

First sketches for my product for The Product Life Cycle assignment. With this device you can listen to music through your teeth. The metal vibrates and the vibrations go through your jaw bone to your eardrum; they cause the eardrum to vibrate which means you hear the sound of the song you are playing. So you don't hear the song by sound waves coming through your ear, but you hear the song by vibrations that go from your teeth and jaw bone to your eardrum.
