Abstract
Official abstract text for this publication.
A loudspeaker device is installed in a space between a bumper reinforcement for reinforcing a bumper of a vehicle and a bumper absorber attached to a front side of the bumper reinforcement. An approach notification sound output from a front side of the loudspeaker device is radiated outside through a first opening provided on a driver's seat side of the bumper absorber. An approach notification sound output from a rear side of the loudspeaker device passes through a sound path between the bumper reinforcement and the bumper absorber and is then radiated outside through a second opening provided on a passenger seat side of the bumper absorber.
