Document Type and Number:
WIPO Patent Application WO/2020/095517
Kind Code:
A1
Abstract:
A control device for a parametric speaker is provided with: a means for acquiring three-dimensional layout information related to a three-dimensional layout of a used space in which the parametric speaker is used; a means for acquiring simulation conditions including both first position information related to the position of a first area in which audible sound formed by ultrasonic waves emitted from the parametric speaker is to be generated and second position information related to the position of a second area in which the traveling of the ultrasonic waves is to be inhibited; a means for selecting, on the basis of a combination of the three-dimensional layout information, first position information and second position information, that one of a plurality of paths between the parametric speaker and a target person along which the audible sound is to be generated in the first area and along which the audible sound is not to be generated in the second area; and a means for producing, on the basis of a selection result of the selecting means, a control signal for controlling the path of the ultrasonic waves emitted from the parametric speaker.
