Charging Your Phone With Sound? Well Xiaomi’s New Patent Has Something to Say

By Aswin Kumar

Xiaomi has filed a patent with the China National Intellectual Property Administration for a system that uses sound to charge the smartphone.

The Chinese smartphone maker has developed a technology that uses sound to charge mobile devices. The patent states a mechanism that converts vibration from soundwaves to electrical energy or AC current then it is converted into DC current for charging smartphones.

Xiaomi has also filed a patent for its ‘Air Charger’ in January this year which is a technology that enhances the current wireless charging technology using induction but this time Xiaomi wants to level up the game by introducing ‘Sound Charger’, I guess that a good name!

The Chinese maker never fails to surprise us with innovation. Earlier they also had developed a fast-charging technology called ‘Hyper Charger’ which uses a 200W charging dock to completely charge the phone within 8 mins, which I think is insanely fast if you are a last-minute person like me!


“The core technology of Xiaomi’s remote charging lies in space positioning and energy transmission. Xiaomi’s self-developed isolated charging pile has five phase interference antennas built-in, which can accurately detect the location of the smartphone.”, said the company.

“A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming,” they further added.

Meanwhile, technologies like this could make our life easier and improved consumer technologies, or at least this patent is more meaningful than “Apple iPad Pro with M1 with no full suite app support”.
