ACOUSTIC CHARACTER PREDICTING AND OPTIMAL PLAN VARIABLE PREDICTING METHOD

摘要

The present invention relates to a loudspeaker acoustic characteristic prediction and optimal design parameter prediction method.;According to the present invention, a speaker is modeled using the orthogonal array table of Dacuzzi according to the number of design variables and the level of each design variable related to the acoustic characteristics in speaker design, and the acoustic characteristics of each of the modeled speakers are predicted and By using the predicted acoustic characteristics, it is possible to predict the optimal design variables and their levels, and provide the designer with a method of predicting the optimal design variables and their levels when designing the speakers. By greatly reducing the vibration model of the speaker by using the orthogonal array table of Dakuchi, the vibration and sound analysis time of the speaker is not only shortened, but also a combination of multiple design variables and levels of each design variable. Even models of all speakers can be vibrated, analyzed, and predicted by optimal design parameters.
