Abstract

Configurations and methods of wireless sound power transmission using a laptop computer may include a transmitter and/or a receiver embedded in the laptop screen. The embedded transmitter may emit SW waves for the generation of pockets of energy that may be utilized by receivers in peripheral devices for charging or powering. Meanwhile, the receiver embedded in the laptop computer may collect SW waves from a separate transmitter for charging or powering the laptop computer.
