The sound energy

Dec 02, 2023 11 months ago

I was in the computer science lesson, learning about speakers (devices responsible for amplifying sound) and microphones. When the teacher presented the features and components of the speaker, I had a brilliant and astonishing idea that we could generate electricity from sound. In reality, a speaker converts electricity to produce sound, while a microphone performs the opposite function. When we make a sound into a microphone, the diaphragm of the device vibrates and moves the coil inside, cutting the magnetic field within it. This process allows us to generate electricity, albeit in small amounts. Despite the low energy output, we discovered an almost unlimited source of energy. If we position the device in the middle of the walls of every room and connect them to a battery, we could obtain at least 480mW of energy. Although this amount of energy is relatively low, it can effectively recharge fitness trackers or smartwatches. Placing these devices in noisy streets, factories, or dance clubs could even allow us to recharge electric cars. Ultimately, we could generate electricity wherever it is needed. This highlights an advantage of sound energy over other sources like wind energy.
