Abstract
The invention relates to a device for manual, mechanical reproduction of short audio information, consisting of a flat, multilayered material (1) in which a longitudinal profile (2) is embossed. The embossing die is produced by means of a milling process.
Claims20
A device for reproducing recorded sound, said device comprising:
- a membrane capable of mechanical oscillation;
- an elongated substrate formed from compressible material, said substrate being integrally bonded to said membrane so that said membrane and said substrate move in unison wherein the material forming said substrate is selectively compressed so as to define a sequential series of peaks and valleys, the peaks and valleys collectively defining a varying height surface relief that extends along a longitudinal length of said substrate;
- and
- a contact layer disposed over and bonded to said elongated substrate, said contact layer being formed from one from the group consisting of:
- lacquer;
- plastic;
- metal;
- and ceramic and said contact layer is shaped to have an outer surface that is shaped to have a surface relief that corresponds to the surface relief of said elongated substrate and is further shaped so that the application of a scanning object along the length of said contact section results in the oscillation of said substrate and said membrane that generates a recorded sound.

A device for reproducing recorded sound, said device comprising:
- a substrate formed from compressible material, said substrate having:
- an elongated section that is compressed so as to define a sequential series of peaks and valleys, the peaks and valleys collectively define a varying height surface relief that extends along a longitudinal length of said elongated section;
- and
- a membrane section that is contiguous with said elongated section, said membrane section having an outer surface;
- and
- a contact layer disposed over and bonded to said substrate elongated section, said contact layer being formed from one from the grouping consisting of:
- lacquer;
- plastic;
- metal;
- and ceramic and said contact layer is shaped to have a contact surface that is shaped to have a surface relief that corresponds to the surface relief of said substrate elongated section and that is further shaped so that the application of a scanning object along the length of said contact section results in the generation of a recorded sound by said substrate and said outer layer;
- and
- wherein, said substrate elongated section is compressed to such an extent and said contact layer has a thickness so that the contact surface of said contact layer is located below the outer surface of said substrate membrane section.
