In a device for generating acoustic signals, a mechanical profile which contains information in a coded form is arranged on the surface of a plastic card, can be led over an edge for generating sounds which contain the information, and has at least two adjacent tracks. The plastic card can be inserted into a guiding part, for example a card slide, provided with at least one scanning cam of which one edge rattles on the profile when the profile is drawn past it.
L'invention concerne un dispositif servant à la génération de signaux acoustiques, dans lequel un profil mécanique à au moins deux pistes voisines, contenant des informations sous forme codée, est réalisé à la surface d'une carte en plastique. On fait glisser ce profil mécanique sur une arête pour générer des bruits qui contiennent les informations. A cet effet, on introduit la carte en plastique dans un élément de guidage, par exemple un étui pour carte, qui présente au moins un ergot de lecture dont une des arêtes cliquette sur le profil lorsqu'on fait passer le profil.
