Abstract

본 발명은 회전기를 사용하는 가전제품의 소음을 줄이기 위한 장치에 관한 것으로, 특히 회전기로부터 발생하는 소음이나 잡음을 입력신호로 받아들여 소음 감쇄장치에 의해 입력신호의 위상과 위상이 180° 반전된 신호를 출력하여 상기 두 신호를 합성함으로서, 회전기로부터 발생하는 소음을 최소화시키는 소음 감쇄장치치에 관한 것이다.The present invention relates to a device for reducing the noise of a home appliance using a rotating machine, and in particular, a signal in which the phase and phase of the input signal are inverted by 180 ° by a noise attenuation device by receiving the noise or noise generated from the rotating machine as an input signal. By outputting the two signals by synthesizing, it relates to a noise reduction device value to minimize the noise generated from the rotor.
