摘要
某型号冰箱开发过程中发现周期性波动噪声,对整机声品质产生严重影响。分析发现该异常噪声主要由压缩机拍频振动引发底板共振导致,针对该问题提出了改善方案,经验证主观感受及客观评价均取得了良好的效果。
One periodic waving noise is detected in development stage of refrigerator,which affects noise quality of refrigerator severely.This noise is generated by the beating from compressor which can result in resonance on bottom plate.One optimized solution was proposed,which satisfies user experience and objective criteria.
