The present invention relates to a wireless microphone system for a conference, which can implement a clean wireless microphone system environment since there is no cable exposed outward. The wireless microphone system for a conference comprises: a first microphone unit (10) which wirelessly transmits a first identification signal (A1) for identification and a first speaker voice signal (B1) corresponding to a first speaker voice; a second microphone unit (10') which wirelessly transmits a second identification signal (A2) for identification and a second speaker voice signal (B2) corresponding to a second speaker voice; a third microphone unit (10") which wirelessly transmits a third identification signal (A3) for identification and a third speaker voice signal (B3) corresponding to a third speaker voice; a chairman microphone unit (20) which generates a chairman voice signal (C) corresponding to a voice of a chairman, who leads the conference, and wirelessly transmits a chairman control signal (D) for controlling a specific microphone unit for smooth progress of the conference; an amplification speaker (30) which amplifies the wirelessly received first, second, and third speaker voice signals (B1, B2, B3) and the chairman voice signal (C) into a voice that humans can hear to output the same; and a controller (40) which wirelessly connects the first, second, third microphone units (10, 10', 10"), the chairman microphone unit (20), and the amplification speaker (30). 본 발명은 회의용 무선 마이크 시스템에 관한 것으로서, 식별을 위한 제1식별신호(A1) 및 제1발언자 음성에 대응되는 제1발언자음성신호(B1)를 무선으로 송신하는 제1마이크유닛(10)과; 식별을 위한 제2식별신호(A2) 및 제2발언자 음성에 대응되는 제2발언자음성신호(B2)를 무선으로 송신하는 제2마이크유닛(10')과; 식별을 위한 제3식별신호(A3) 및 제3발언자 음성에 대응되는 제3발언자음성신호(B3)를 무선으로 송신하는 제3마이크유닛(10")과; 회의를 진행하는 의장의 음성에 대응하는 의장음성신호(C)를 생성하고, 회의의 원활한 진행을 위하여 특정 마이크유닛을 제어하기 위한 의장제어신호(D)를 무선 송신하는 의장마이크유닛(20)과; 무선으로 수신되는 상기 제1,2,3발언자음성신호(B1)(B2)(B3) 및 의장음성신호(C)를 사람이 청취할 수 있는 음성으로 증폭하여 출력하는 증폭스피커(30)와; 상기 제1,2,3마이크유닛(10)(10')(10"), 의장마이크유닛(20), 증폭스피커(30)를 무선으로 연결하는 콘트롤러(40);를 포함하는 것을 특징으로 한다.
