Abstract

Selon l'invention, une unité de formation de signaux sonores d'imitation forme des signaux sonores d'imitation de moteur, sur la base d'informations de déplacement d'un véhicule (CR) acquise à l'aide d'une unité d'acquisition. Les signaux sonores d'imitation de moteur sont fournis en tant que signaux sonores à un dispositif de sortie de sons (100A), après amplification de puissance. Dans le dispositif de sortie de sons (100A), des actionneurs de vibration (1201, 1202) se mettent individuellement à vibrer en fonction des signaux sonores fournis. Ensuite, la face latérale d'un élément tubulaire (110A) fixant les actionneurs de vibration (120j) (j=1+2) vibre par mouvement vibratoire de ces derniers, générant ainsi des sons d'imitation de moteur. Ainsi, une partie des sons d'imitation de moteur générés, est émise en sortie vers l'extérieur du véhicule (CR) à partir d'ouvertures situées aux deux extrémités de la direction axiale Y (direction de la largeur du véhicule) par propagation dans l'espace interne de l'élément tubulaire (110A). Par conséquent, il est possible d'émettre en sortie vers l'extérieur du véhicule et de manière appropriée, les sons d'imitation de moteur générés constituant des sons évoquant un véhicule.
