Xiaomi recently unveiled its Mi Air Charge technology, which is a hybrid of wired and wireless charging. You might also add “via sound” to the list in the future. The looks similar to the previously featured Mi Air wireless Charger by Xiaomi on SmarttechVilla
Xiaomi has worked out a way to charge cellphones using sound; this system does not rely on power outlets.
In China, the business has filed a patent for a technique that outlines how this sound-based charging system works.
Although there is no proof of concept yet, the device could theoretically charge your phone simply by using sound. It would appear that living in a house full of crying babies and barking dogs would make sense.
Given that this is still in the patent stage, we may have to wait a few years before seeing a working prototype and, eventually, a commercially ready product.
A sound charging device, an energy storage device, and an electrical gadget are all part of the system.
To transform it from environmental to mechanical vibration, the sound charging stage includes a “sound gathering device, a plurality of energy conversion devices, and a power conversion device.”
This mechanical vibration will be transformed to alternating current (AC) by the electronic device, which will then be converted to direct current (DC) by the power conversion device.
This will then charge your smartphone or whatever device you’re trying to charge.
In layman’s terms, this will first consist of a pair of machines that use sound to generate mechanical energy, which will then be passed through some ingenious technology to create the magic of electricity.
The prospect of such a system is intriguing, but it remains to be seen how successfully Xiaomi can put it into practice in a commercial setting.
Is Xiaomi capable of pulling it off? The company has made significant progress in the field of smartphone charging in the past. With a promised charging period of 8 minutes for a device with a 4000mAh battery, its recently announced 200W charging solution garnered notice.
