Xiaomi invests heavily in R&D and is continuously working on different charging solutions. The company recently showcased its 200W HyperCharge technology and a while ago, teased Air Charge as well. But that’s not all. To further push the boundaries of charging technology, Xiaomi has filed a new patent for charging devices via sound.
Xiaomi sound charging patent:
Xiaomi has applied for a patent at the CNIPA (China National Intellectual Property Administration) which reveals some key details of the upcoming charging solution.
Sound is the new source
Every year, companies demonstrate their take on fast smartphone charging technology. We reported a few days earlier that Infinix is possibly working on a flagship phone with 160W fast charging. If the company indeed delivers the product to the market, Infinix NOW will boast the fastest charging speed among any phone you could buy.
Xiaomi, on the other hand, has been pulling the curtains on unique and intriguing charging concepts in order to lead the market. The new sound charging technique is helping them get closer to their objective.
Per the patent, the charging method can charge smartphones and other electronic devices without the use of a power outlet. The Sound Charging device contains a “sound collection device, a plurality of energy conversion devices, and a power conversion device” to convert environmental vibration to mechanical vibration, according to the patent description.

The device will then convert this mechanical vibration into alternating current (AC), which will be converted to direct current (DC) by the power conversion device.
This novel method of wireless charging is a first for the industry. However, it is still only a patent, and the practical use of such technology will require more research. That is not to say Xiaomi will not demo sound charging technology in the near future.
When it comes to commercializing a breakthrough technology, several things must be considered. So, we’ll have to wait and see whether Xiaomi will reveal additional information in the coming days about its sound charging technology or not.
