A hearing aid earpiece (1) is provided, that is custom fitted to the individual shape of the ear canal of a user and manufactured in a rapid prototyping process. The earpiece comprises a sound conduit (3) that is adapted for conveying an acoustic signal from an acoustic inlet port towards an acoustic outlet port and wherein the sound conduit is looped such that at least one geometrical plane, will intersect the sound conduit at least three times thereby providing a length of the sound conduit exceeding a largest outer dimension of the hearing aid earpiece. The invention also relates to a hearing aid comprising such a hearing aid earpiece and a method for manufacturing such an earpiece.
Linvention concerne un écouteur (1) de prothèse auditive, adapté sur mesure à la forme propre du conduit auditif externe dun utilisateur et fabriqué à laide dun processus de prototypage rapide. Lécouteur comprend un conduit sonore (3) conçu pour acheminer un signal acoustique entre un orifice dentrée acoustique et un orifice de sortie acoustique, le conduit sonore étant bouclé de telle sorte quau moins un plan géométrique le coupe à au moins trois reprises en lui donnant ainsi une longueur excédant une dimension extérieure maximale de lécouteur de prothèse auditive. Linvention concerne également une prothèse auditive comprenant cet écouteur ainsi quun procédé de fabrication de cet écouteur.
