The patent abstract shows that the present exposure is a sound charging device, consisting of a sound collection device, a number of energy conversion devices, and a power conversion device.  It converts the sound in the environment into mechanical vibration, then converts the mechanical vibration into alternating current, and finally the alternating current to direct current.

In this representation, the user can use the sound of the surrounding environment to charge the electronic device without looking for a power socket, thereby reducing the difficulty of charging and improving the user experience.

Talking about Xiaomi’s Black Charging technology, apart from the recently announced maximum of 200W wired charging and 120W wireless charging by the company, in January this year Xiaomi first launched its self-developed Mi for mobile phones Air Charge technology ( Mi Air Charge) for smartphones.
