The Bicycle Vibration Speaker Is a Neat Idea with Little Chances to Work

This concept design comes from Nora Hipsher and it is aimed at enabling your bike with the power of sound. No, it doesn't involve strapping a ghettoblaster to your ride, even though it has something to do with speakers.

The idea is to attach a special transducer to the bike's frame and using a special vibrating component to make everything resonate and produce sound. If you are familiar with bone-transmitted sound, then you already know everything there is to know about the Bicycle Vibration Speaker.

Because the idea involves old-school technology infused with modern technology, the whole thing is Bluetooth-enabled so the device can be easily paired to any smartphone or portable media player. Control buttons can be effortlessly accessed for adjusting the volume, track skipping or powering off, while secure screws make taking this baby off the frame impossible without a special driver.

How about road vibrations?

We believe that trying to actually prototype this gadget is worth a try. However, when vibration is the sole thing that creates sound, we cannot help thinking about the vibrations caused by actually riding the bike on the road.

They would interfere with our device and the vibrations it produces and the sonic result would be poorer. Even in ideal conditions, the vibrations produced by the Bicycle Vibration Speaker would have to be very powerful in order to cause the frame to produce a sound that's more than some faint mumbling.

We dealt with magnetostriction and Terfenol-D speakers before, but they were attached to large window panes made of glass or other similar surfaces that have too little in common with the metal frame of a bike.

The project could be upgraded with the addition of a resonator plate, maybe, but we're already on trodden paths. Namely, strapping a Bluetooth speaker to the bike, the modern, yet still old-fashioned way. Anyway, as an exercise in design, we love this idea.
