ULTRASONIC WIRELESS COMMUNICATION APPARATUS AND METHOD FOR WIRELESS POWER TRANSMISSION

摘要

PURPOSE: An ultrasonic wireless communication device and a wireless charging method thereof maximize ultrasonic energy transmission efficiency and directivity. CONSTITUTION: An ultrasonic generator (115) generates an ultrasonic signal for power transmission. A signal processor (112) modulates the ultrasonic signal. A power amplifier (113) amplifies the modulated ultrasonic signal to a predetermined size. An ultrasonic transceiver (114) transmits the amplified ultrasonic signal to an ultrasonic wireless power receiving device. The ultrasonic transceiver receives an ultrasonic signal for data transmission from the ultrasonic wireless power receiving device.
