PARAMETRIC SPEAKER AND ACOUSTIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the degree of freedom of installation and portage of a parametric speaker.SOLUTION: A parametric speaker 20 includes a plurality of ultrasonic transducers 288-1 to 288-5 arranged along an X axis and a Y axis and generating ultrasonic waves in a direction along a Z axis; a reflection section 400 having reflecting surfaces 410-1 to 410-5 provided opposite the plurality of ultrasonic transducers 288-1 to 288-5, and reflecting the respective ultrasonic waves from the plurality of transducers 288-1 to 288-5 in a direction along the Y axis; and an emission opening 312 for emitting the ultrasonic waves reflected by the reflecting surfaces 410-1 to 410-5 to the outside.
