Abstract

본 고안은 하울링 제거장치에 관한 것으로서, 마이크와 스피커를 사용하는 통신기기와 음향기기에 설치되어 마이크에 입력되는 음성신호와 하울링신호를 필터링하여 검출하여 하울링신호를 제거한 후 출력하도록 하고, 마이크에는 제1 증폭기를 더 구비하여 사용자가 마이크와 거리를 둔 상태로 사용하더라도 그 입력신호가 동일하게 출력시키도록 하였으며, 중앙처리부에는 경음악등의 음향데이타가 저장된 메모리부를 연결하여 에코기능과 함께 음향데이타를 출력시키도록 하였고, 마이크의 비사용시 이를 타이머로 카운터하여 그 신호를 중앙처리부를 통해 음성출력장치의 전원공급을 전원차단장치로서 선택적으로 차단시키도록 하였으며, 음성출력장치에 리모콘수신부를 연결하고, 리모콘 송신부로서 음성출력장치의 볼륨조정이나 메모리부의 음향데이타의 출력을 원격제어토록 함으로써 사용상의 편의성을 증대시킨 것이다.The present invention relates to a hauling remover, which is installed in a communication device using a microphone and a speaker and a sound signal inputted to a microphone and a howling signal, 1 amplifier so that the input signal is output in the same manner even if the user uses the microphone with a distance from the microphone. In the central processing unit, a memory unit storing acoustic data such as instrumental music is connected to output acoustic data When the microphone is not in use, it is counted by a timer, and the signal is selectively cut off as a power cutoff device through the central processing unit as a power cutoff device. The remote control receiver is connected to the voice output device, The volume control of the sound output device or the The output of the sound data is remotely controlled, which enhances convenience of use.
