Abstract

L'invention traite d'une pièce de carrosserie (1) de véhicule automobile. Cette pièce (1) comprend un corps principal (2) en matière plastique ayant au moins une face externe visible depuis l'extérieur du véhicule lorsque la pièce (1) est montée sur le véhicule et une face interne (21) opposée à la face externe et au moins un transducteur piézoélectrique (3) configuré pour concentrer une émission d'ondes sonores selon un nombre fini de directions de propagation (A1, A2) sur l'une au moins de la face externe ou de la face interne (21) du corps principal (2) en fonction d'une fréquence d'excitation donnée, le transducteur piézoélectrique (3) étant aussi apte à émettre des ondes sonores ayant une vitesse de groupe nulle ou sensiblement nulle.
