Abstract
Portable and foldable modular electronic keyboard which includes a keyboard having a plurality of white and black keys capable of reproducing the notes of a piano through an individual headphone by using associated electronics. The foldable keyboard is formed from a plurality of modules, each module having a plurality of white and black keys, and each module being joined to another module by a flexible membrane. When the modules are folded together, the keyboard has the volume of a book. When the modules are unfolded, the keyboard presents a genuine piano keyboard with seven octaves. The white keys and the black keys forming each module have a low thickness.
Claims12
A portable, foldable modular electronic piano, comprising
- i) a device for generating electrical signals corresponding to the notes of a piano, which device includes a preamplifier;
- ii) a plurality of modules, with each module comprising a plurality of white keys and black keys operatively connected to said device;
- and
- iii) at least one flexible membrane which joins the modules together, wherein the membrane is sufficiently flexible to permit the modules to be folded over one another when not in use, and unfolded when the keyboard is to be used, such that when unfolded, the plurality of modules simulates a piano keyboard having seven octaves,
- iv) a plurality of contacts operatively connected to and located under each key so as to permit selection of a particular sound level from a number of sound levels corresponding to the number of said contacts,
- wherein said contacts comprise piezoelectric contacts which generate a current corresponding to an amount of mechanical energy exerted upon a corresponding key, and
- wherein said device is contained within said plurality of modules.
