First Claim
1. An ultrasonic short-range wireless power transmission system comprising:
- an ultrasonic transmission transducer configured to transmit power,wherein the ultrasonic transmission transducer comprises;
a converter configured to convert power received from an external power source;
a controller configured to control power of a modulator and power of an amplifier;
a communication unit configured to communicate with an external reception transducer;
a sensor configured to sense ultrasonic waves transferred from an ultrasonic wave emission region;
the modulator electrically connected to the controller and configured to generate a signal for ultrasonic short-range wireless power transmission; and
the amplifier configured to amplify a modulation signal generated by the modulator and convert the modulation signal into power; and
one or more transmission modules configured to receive the power from the amplifier and convert an electrical reception signal into ultrasonic waves.
