Estimation of Speaker Acoustic Characteristics and Prediction Method of Optimal Design Parameters

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a speaker acoustic characteristic prediction method and an optimum design variable prediction method.;According to the present invention, the loudspeaker is modeled by using the orthogonal array table of the microwaves according to a plurality of design parameters related to the acoustic characteristics and the level of each design variable at the time of designing the loudspeaker, and the acoustic characteristics for each of the modeled loudspeakers are predicted By using this predicted acoustic characteristics, it is possible to predict the optimal design variables and their levels. By providing a method of predicting the optimum design parameters and the level of the speaker to the designer in designing the speaker, The oscillation model of the loudspeaker is generated by using the orthogonal array table of TAKUKI, so that the period of time required for the vibration and acoustic analysis of the speaker is shortened and the combination of the plurality of design variables and the level of each design parameter It is possible to analyze vibration and sound of all speaker models and to predict optimal design parameters.
