Document Type and Number:
WIPO Patent Application WO/2019/083100
Kind Code:
A1
Abstract:
A smart watch according to the present invention comprises: a reception unit to which an analog speech signal is inputted; a first amplification unit for amplifying the analog speech signal inputted through the reception unit; an A/D converter for converting, into a digital speech signal, the amplified analog speech signal outputted from the first amplification unit; a control unit for receiving and outputting the digital speech signal outputted from the A/D converter and outputting a digital speech signal received and inputted through an antenna; an RF transceiver for controlling signals such that the signal received through the antenna is inputted to the control unit, and the signal outputted from the control unit is transmitted through the antenna; a D/A converter for converting the digital speech signal outputted from the control unit into an analog speech signal; a second amplification unit for amplifying the analog speech signal outputted from the D/A converter; and a speech output unit for outputting, to the outside, the analog speech signal outputted from the second amplification unit, wherein the control unit enables full duplex communication with another wireless communication device through time division function control of the antenna.
