ABSTRACT:
This invention relates to electronic devices for producing musical sounds. More particularly, the present invention relates to a portable and foldable modular electronic piano.
BACKGROUND OF THE INVENTION
Though the world of music is full of pleasure, musicians must play regularly and assiduously. A pianist for example, even an amateur, must practice almost everyday in order to keep his fingers nimble and to achieve and maintain perfect control of the keyboard.
Now, whereas a harmonica player or a violinist can carry their instrument, a pianist faces real difficulty in transporting his piano.
Of course, electronic keyboards which are easier to carry than a piano have appeared. However, existing models are still cumbersome, even though they only have a four-octave or five-octave keyboard. For example, German patent 9208106 discloses a keyboard capable of being folded in two parts, thus enabling easier transport, but the features of this keyboard (weight, size, operating mode) are still identical to those of existing keyboards that typically have only five octaves.
SUMMARY OF THE INVENTION
An object of the invention is to provide an ultra-light, foldable and unfoldable piano keyboard which is easy to carry.
Another object is to provide a foldable keyboard having the
7
octaves of a genuine piano keyboard.
Yet another object is to provide a portable keyboard whose size, once folded, is not higher than that of a book and, once unfolded, provides everyone an inexpensive means to practice with an instrument whose tone is similar to that of a real piano.
An advantage of the present invention is that it permits easy practice at all times because, once unfolded, the keyboard is similar to a real piano keyboard.
