The Tone by Wei Hua Huang from taiwan
designer's own words:
I use the saxophone parts to assemble the bicycle. It made of brass.
It is the project logo without instruction.
Many people install a smart phone holder on their bicycle and use headphones while riding bike.However, I want to change the constant form. 
I observed the speaker’s structure. Why not make the best use of the bicycle’s hollow tubes? Just need to slightly change the tube into a channel which can expand the sound. As long as plug your smart phone on. It becomes an unplugged audio device!
This is the 3D model.
