A new patent filing emerged on the Chinese National Intellectual Property Adminstration website.
According to the patent, the technology will apparently help to charge devices through sound. The setup will involve a sound charging device, an energy storage device, and an elctronic device. The sound charging device will consist of a sound collection device, multiple enrgy conversion devices and a main power conversion device.
The sound collection device will seemingly convert the sound in the environment to mechanical vibration and conduct the mechanical vibration to the energy conversion device.
In addition to this, the energy conversion device will convert the mechanical vibration into Alternating Current. The power conversion device will then convert this AC input to Direct Current in order to charge the device.
Sound Charge’s patent claims that the users can charge the device without connecting it to a power socket.
It seems plausible as sound charging does aim to be a true wireless charging solution. The efficiency of this setup is yet to be proven and we will have to see it for ourselves once it is commercially available.
This is just a patent filing, there is no guarantee that Xiaomi will actually release a product integrated with this technology. It is, however, an interesting concept to be on the lookout for.
