이퀼라이져를 이용한 모터의 불량 검사방법Motor defect inspection method using equalizer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 의한 마이크 특성검사 구성도, 제2도 (가),(나)는 중음의 스피커에 의한 마이크 특성파형도 제3도 (가),(나),(다) 는 저음스피커에 의한 오디오마이크 특성파형도.1 is a configuration diagram of the microphone characteristic test according to the present invention. FIG. 2 (a) and (b) is a microphone characteristic waveform diagram of a mid-range speaker. FIG. 3 (a), (b) and (c) is a bass speaker. Audio microphone characteristic waveform

Claims (2)

노이즈를 받아들이는 마이크의 출력이 필터를 통하여 설정된 대역으로 필터링되고, 필터링된 신호가 검사기에서 검사되며, 필터링된 신호는 또한 오디오앰프에서 증폭되어 이퀼라이져 디스플레이에 나타나게 함으로써, 검사기와 이퀼라이져 디스플레이에 의한 출력에 의하여 노이즈 여부를 판별하도록 함을 특징으로 하는 이퀼라이져를 이용한 모터의 불량검사방법.The output of the microphone receiving the noise is filtered into the band set by the filter, the filtered signal is inspected by the inspector, and the filtered signal is also amplified by the audio amplifier so that it appears on the equalizer display, so that the output by the inspector and equalizer display is reduced. The defect inspection method of the motor using the equalizer, characterized in that to determine whether or not by noise. 제1항에 있어서, 상기 필터는 454800Hz를 통과시키는 밴드패스 필터임을 특징으로 하는 이퀼라이져를 이용한 모터의 불량검사방법.The method of claim 1, wherein the filter is a band pass filter passing 454800 Hz. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
