TACTILE OR HAPTIC DEVICE, AND A MUSICAL KEYBOARD WITH AT LEAST ONE SUCH SIMULATION DEVICE
First Claim
1. A chromatic keyboard musical instrument equipped with twelve keys per octave, of the piano type with at least one tactile or haptic sensory simulation device associated with at least one of said keys, where said device is intended to oppose the movement of said key with a reaction reflecting the operation of the control, where said device has a chamber containing a magneto-rheological fluid, at least one mobile element designed to shear the magneto-rheological fluid and intended to be linked mechanically to said key, where said element has at least one blade designed to shear the magneto-rheological fluid, with said element being mobile between two predetermined positions, at least one sensor with a high cinematic or dynamic range that is representative of the movement of this element or of the control component, and a control component and a generator of a suitable magnetic field around the chamber, with said sensor being linked to the control component, which itself is linked to the generator of a magnetic field, the whole being such that the apparent viscosity of the magneto-rheological fluid varied during movement of said key.

Abstract
A tactile or haptic sensation simulation device designed to oppose the movement of a manual control component with a reaction reflecting the movement of the control, where the said device has a chamber containing a magneto-rheological fluid, a mobile element interacting mechanically with the fluid and intended to be linked mechanically to the control component, where the said element is mobile between two predetermined positions, at least one sensor with a cinematic and/or dynamic range that is representative of the movement of the control component, a control component and means for the generation of a suitable magnetic field around the chamber so as to apply a magnetic field that is dependent on the dynamic characteristics to be simulated for the movement of the manual control component, and the real-time measurements, the whole being such that the apparent viscosity of the magneto-rheological fluid varies over the travel of the manual control component.
