This paper focuses on the transfer characteristics of the structure and describes the investigation of structural modifications aimed at vibration reduction. Numerical analysis is being conducted to investigate a structure that lowers energy transmittance, namely, lowers coupling loss factor, by providing the vibration-reducing ribs to prevent vibration transmission. We applied the proposed method to a handheld vacuum cleaner with three elements connected in series, and examined the effectiveness of the vibration reduction effect on the handle element and the reduction effect on the radiation sound pressure.
