Abstract
An analysis device constructs an analytical model with a circuit board and a medium, and applies a concentrated load grouping composed of concentrated loads to the circuit board. In this case, the concentrated loads are established such that the sum of the respective vectors is zero, and such that the torque is zero with respect to the center of gravity. The analysis device applies a finite element method to the analytical model to figure out the vibration of the circuit board, which is caused when the concentrated loads vibrate with a constant period. The change in the pressure of the medium is computed from the vibration of the circuit board, and the change in the pressure is converted to a sound pressure.
