Abstract :
This paper deals with the electromagnetic-structural acoustically coupled analysis method of optical image stabilizer voice coil motor using finite element method. Using the analysis method, the cover structure of the voice coil motor is redesigned to reduce acoustical noise. The validity of the analysis method is verified through the comparison with the measurement of a prototype.
