Abstract
본 발명은 세탁기의 구동시 발생되는 소음을 역위상음파의 간섭에 의해 감쇄시킬 수 있게하는 세탁기의 소음감쇄장치에 관한 것으로, 이는 구동부(5)로 부터 발생되는 소음을 역위상 음파로 간섭하여 상쇄시킬 수 있도록 구동음의 신호를 전기적신호로 전환시키는 음파입력수단(61)을 갖추고 상기 음파입력수단(61)으로부터 입력된 전기적신호를 증폭시키는 증폭수단(62)과, 상기 증폭수단(62)으로부터 증폭된 신호를 180°위상으로 지연시키는 지연수단(63)을 갖추며, 상기 지연수단(63)으로부터 지연된 180°위상신호를 출력시키는 음파출력수단(65)이 구성되어 이루어진 것이다The present invention relates to a noise reduction device of a washing machine that can attenuate the noise generated when the washing machine is driven by the interference of anti-phase sound waves, which is offset by interfering the noise generated from the driving unit (5) with anti-phase sound waves. An amplification means 62 for amplifying an electrical signal input from the sound wave input means 61 and having a sound wave input means 61 for converting a signal of a driving sound into an electrical signal so as to be capable of being made. And a delay means 63 for delaying the amplified signal to 180 ° phase, and the sound wave output means 65 for outputting the delayed 180 ° phase signal from the delay means 63.
