以EASE中的扬声器数据库为例,谈一谈怎样通过选择某一型号扬声器来查看其技术特性指标。通过扬声器特性查看与相应厂家扬声器技术手册数据对比,加深对扬声器数据库的认识和理解。首先介绍扬声器坐标系及相关约定,然后介绍如何查看扬声器特性曲线图,包括频率响应曲线、指向性因子、指向性指数、灵敏度特性、最大功率、最大声压级、极坐标下的指向性、覆盖角特性等。
Taking the speaker database in EASE as an example, let’s talk about how to select a model speaker to see its technical specifications. Through the speaker characteristics and the corresponding manufacturer speaker technical manual data comparison, to deepen understanding of the speaker database and understanding. First introduce the speaker coordinate system and related conventions, and then introduce how to view the speaker characteristics graph, including the frequency response curve, directivity factor, directivity index, sensitivity characteristics, maximum power, maximum SPL, polar coordinates, coverage Angle features.
