Different from conventional loudspeakers, a parametric loudspeaker system uses the nonlinear properties of air to produce audible sound within the air using a set of ultrasonic waves. The parametric loudspeaker system has many benefits, including controlled sharp directivity, projection of audio sound over long distances while maintaining intelligibility, use of thin non-magnetic emitters. This prospective loudspeaker system is drawing special attention as a next-generation acoustic transducer among acoustic engineers in the world. This report outlines the parametric loudspeaker system in terms of historical background, basic principle and configuration, trends on research and development, patents, current products, and field of application.
