The study on the woofer speaker characteristics due to design parameters
2014
In the vehicle speaker, because the sound characteristics are changed by the space of vehicle which mount the speaker, the speaker elements should be determined according to sound field. In this study, the nonlinear characteristics, the frequency response and the sound pressure for the same size speakers which is adapted to domestic vehicle model are investigated. The vehicle model is classified to semi-midsize, midsized, full size vehicle in order to change the vehicle space. As a result, we can investigate the differences of the force factor and the stiffness of suspension system for speaker. According to the change of the speaker characteristics, the sound pressure is changed, also. In the future, these data will be used to investigate the correlation between the sound quality and measurement data.
