African drum charger / African drum charger

African drum charger

The African drum charger uses the conversion relationship from kinetic energy to electric energy, and uses a small amount of electric energy storage generated by tapping the drum surface to charge smart phones, which solves the problem of how to charge mobile phones for African people.
Usually the acoustic-electric system passes through the middle ring, first converts sound energy into mechanical energy (sound wave/beating), and then converts it into electrical energy.
