Hear thru your bones!!!
1. 3.5mm audio jack
2. Small dc motor (3 volts or less)
3. soldering iron
4. Wire cutters
6. Headphone amp (optional)
Step 1: How It Works
A motor vibrates your bones and bypasses the ear drum so no heareing damage is caused
Step 2: Cut a Cable With a 3.5mm Plug on Its End or Make Your Own With a 3.5mm Plug and Some Wires
Step 3: Soldering the Motor
Solder any end of the motor to the ends of the 3.5mm plug cable
Conect any music player at high volume and bite the tip of the motor or place it behind your ear touching your head (you may need a headphone amp for extra volume depending on the device you are listening to and the voltage the motor )
Step 5: All Done
It might not have the best audio quality but it doesn't damage your ear drums and its also a cool project.
