The Headwave Tag is the device that would turn any motorbike helmet into a speaker. It is stuck to the outside of a helmet and used surface transduction to transmit audio waves into the helmet.
Users need only link the Tag with a smartphone via Bluetooth. By applying sound waves to the helmet which pass through it via transduction, the Tag is then able to fill inside of it with audio. It transmits audio waves through your helmet to produce a sound experience unlike conventional acoustics.
It is made of made out of thermoplastic polyurethane and it measures 123 x 61 mm, extending just over 2 cm out from the helmet. It is able to withstand speeds up to 300 km/h and is both water- and shock-proof. It has a 600-mAh li-ion battery that lasts for around 6-8 hours and is charged via USB.
The Tag is available to order at a price of €299.
