Exploration and Study of Parametric Loudspeaker System
Bao Ke-jin · Audio Engineering · 2005
A new-type of sound propagation system,parametric loudspeaker system,is introduced.This system can realize directional propagation of sound in the air,and it is an emerging technology with extensive applications.The realization of parametric loudspeaker system involves the knowledge of many disciplines,including non-linear acoustics,electronic engineering,computer science and etc.Preliminary exploration and research to the operation principle,structure and implementation method of parametric loudspeaker system are described in the article.
