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.
