1. An ultrasonic wireless power transmission apparatus, comprising:

  • ultrasound generating unit configured to generate an ultrasonic signal for transmitting electric power;

    a signal processing unit configured to modulate the ultrasonic signal;

    a power amplifying unit configured to amplify the modulated ultrasonic signal to a predetermined magnitude;

    an ultrasonic transmitter/receiver unit configured to send the power-amplified ultrasonic signal to an ultrasonic wireless power receiver apparatus or receive the power-amplified ultrasonic signal from the ultrasonic wireless power transmitter apparatus; and

    a control unit configured to calculate a charging time using power amount data received from the ultrasonic wireless power receiver apparatus and calculate a natural frequency by considering a distance to the ultrasonic wireless power receiver apparatus and the size of the ultrasonic transmitter/receiver unit.
