Abstract:
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; anda 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.
