要約(英語): The optical image stabilizer (OIS) system using a voice coil motor (VCM) has recently been widely adopted in digital cameras to minimize blurring and provide image stabilization. Since customers buying digital cameras with an OIS are concerned with the noise level in addition to the primary performance, camera manufacturers have been making efforts to reduce acoustical noise. This paper proposes an electromagnetic-structural-acoustic coupled analysis method that uses the FEM; measurements were carried out for verification. The proposed method was used to redesign the cover structure of the VCM to reduce acoustical noise.
