冰箱的主动降噪系统及其控制方法的研究

Research on active noise reduction system and control method of the refrigerator

现有冰箱噪音问题,尤其是压缩机舱内噪音问题亟待解决。基于此,本文探讨了冰箱主动降噪系统。通过噪音采集单元和降噪前声音检测单元收集冰箱的噪音信息,并根据噪音信息控制降噪振动单元进行反向振动,达到对冰箱进行主动降噪的目的。通过反馈检测单元检测降噪效果并进行反馈,提高噪音处理单元对降噪振动单元控制的精准度。

The existing refrigerator noise problem,especially the problem of compressing noise in the cabin,needs to be solved.Based on this,this paper discusses the active noise reduction system of refrigerator.The noise information of refrigerator is collected by the noise collection unit and the noise detection unit before noise reduction,and the noise reduction vibration unit is controlled by the noise information to achieve the purpose of active noise reduction of the refrigerator.Through the feedback detection unit to detect the effect of noise reduction and feedback to improve the accuracy of the noise processing unit to the noise reduction vibration unit control.
