A keyboard with adjustable touch for a musical instrument, the said keyboard comprising a plurality of keys, each one of which is a lever seating on a pivot point substantially central that divides the lever into two arms, a front one and a rear one, where the front arm forms on its upper part an operation surface and its lower part interacts with a centering guide, and the rear arm comprises, on its upper part, a counterweight and its lower part interacts with a stop where the key seats when in its rest position, where each key comprises a magnet mounted on the rear side, facing another magnet that is mounted on a regulation device which is, in turn, affixed to the musical instrument chassis, where the magnets are substantially placed face to face, opposed by their equivalent faces, the relative position they have to each other generating the effect on the keyboard touch. By means of the modification of position, intensity or polarity, or of these three at the same time, of the magnetic field of the magnets affixed to the regulation device, it can be modified the dynamic response of the keyboard, because of the interaction between the magnetic fields of the magnets affixed to the keys and the regulation device. |
