摘要

在汽车扬声器中,由于安装扬声器的汽车空间会改变声音特性,因此必须根据声场来确定扬声器元件。本文研究了同尺寸扬声器的非线性特性、频率响应和声压。车型分为半中型、中型、全尺寸汽车,以改变汽车空间。由此,我们可以研究扬声器悬架系统的力因子和刚度的差异。根据扬声器特性的变化,声压也随之变化。在未来,这些数据将用于研究声音质量与测量数据之间的相关性。

차종별 우퍼 스피커의 특성에 관한 연구
In the car speaker, because the sound characteristics is changed by the space of car which mount the speaker, the speaker elements must be decide 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 car model are investigated. The car model is classified to semi-midsize, midsized, full size automobile in order to change the car space. As a results, 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.
