Document Type and Number:
WIPO Patent Application WO/2017/169779
Kind Code:
A1
Abstract:
This sound effect generation device for vehicles, which generates engine sound effects on the basis of a vibration sound database including a fundamental wave sound comprising a fundamental frequency component, and a plurality of adjustment wave sounds comprising frequency components other than the fundamental frequency component, is provided with: a travel state detection unit for detecting the travel state of a vehicle; a sound effect generation unit which, on the basis of the travel state of the vehicle, synthesizes the fundamental wave sound and the adjustment wave sounds; and a line-of-sight guidance direction setting unit which sets a line-of-sight guidance direction in which the line of sight of an occupant ought to be directed. The sound effect generation unit increases the output characteristics of sound effects in the line-of-sight guidance direction in comparison to the output characteristics of sound effects in directions other than the line-of-sight guidance direction.
