摘要

PURPOSE: A local area wireless communication device and a call quality improving method thereof are provided to improve the quality of the call through an equalizer including a local wireless communication device.;CONSTITUTION: A microphone(101) receives a voice call. The microphone outputs an audio signal. An equalizer(102) compensates for distorts the signals according to the frequency characteristics of a terminal for the audio signal outputted from the microphone. A wireless communication unit(106) transmits the compensated audio signal to the terminal. A storage unit(110) stores the equalization information to compensate for the signal distortion and terminal identification information for one or more terminals.;COPYRIGHT KIPO 2013;[Reference numerals] (102) Equalizer; (103) Power amplifier; (104) Analog-digital converter; (105) Echo and noise reducer; (106) Wireless communication unit; (107) Digital-analog converter; (108) Audio amplifier; (110) Storage unit; (111) Control unit
