Our Product
What if we can generate energy from sound waves?
Today, we live in a world with a lot of electrical goods, such as computers and smartphones, and many more. Those gadgets are quite useful but consume electricity all the time. In fact, energy consumption per capita had doubled in the past 30 years. The source of energy is limited and we have to find a better way to generate power from more environmentally friendly resources.
So, we will develop a technology that collects sound waves from the air and converts them into electricity. The mechanism is simple. A loudspeaker uses electricity to make a sound, so we will reverse the entire process, converting the vibrations to electrical power. We want to make the world more sustainable by accumulating the small changes we can make.
The name of our product is inspired by a fable of a hummingbird, carrying a single drop of water in her beak to the flames. This story tells us the importance of trying everything in our power that we can, even if we can only make a tiny change at a time. But with your support, our products may change the world!
The Technology
How it works?
(Qingyu Ge, 2017)
The sound wave (air vibration) is received by the receiver, the vibration is amplified by the resonator, and then converted into electrical energy.
By moving the coil back and forth periodically, a voltage is generated between the magnet and the coil (electromagnetic induction).
On the other hand, the speaker vibrates the coil by applying a voltage from the outside to produce sound, so it can be said to be a reverse mechanism.

“It’s perfectly conceivable to absorb that movement and glean useable energy. You’re not going to power a city with it, but you can power small devices.”
