Abstract: front page image
(EN)An acoustic apparatus, including an acoustic driver, acoustically coupled to a pipe to radiate acoustic energy into the pipe. The pipe includes an elongated opening along at least a portion of the length of the pipe through which acoustic energy is radiated to the environment. The radiating is characterized by a volume velocity. The pipe and the opening are configured so that the volume velocity is substantially constant along the length of the pipe.
(FR)Cette invention se rapporte à un appareil acoustique qui comprend un dispositif d'excitation acoustique, relié de manière acoustique à un tuyau de manière à émettre une énergie acoustique dans le tuyau. Le tuyau comprend une ouverture allongée le long d'une partie au moins de la longueur du tuyau à travers laquelle une énergie acoustique est émise dans l'environnement. Le rayonnement est caractérisé par une vitesse volumique. Le tuyau et l'ouverture sont configurés de telle sorte que la vitesse volumique soit sensiblement constante sur la longueur du tuyau.
