Abstract:
The invention relates to an actuator ( 7 ) which comprises: a frame ( 11 ) intended for being in contact with the tactile interface via a contact wall ( 13 ) so as to transmit haptic feedback to the tactile surface; a stator ( 15 ) connected to the frame ( 11 ); a movable core ( 19 ) connected via at least one resilient element to the frame ( 11 ) and intended for being moved by the stator ( 15 ) so as to generate the haptic feedback; an electromagnet ( 17 ) and at least one permanent magnet ( 20 ), one of which is supported by the stator and the other by the movable core ( 19 ). The actuator ( 7 ) also comprises a shock absorber ( 23 ) arranged between the movable core ( 19 ) and the contact wall ( 13 ), and said resilient element is sized so that, when the electromagnet is not powered, the movable core ( 19 ) applies a bearing force towards the contact wall ( 13 ) and, when the electromagnet is powered according to a predetermined polarisation, the movable core ( 19 ) moves away from the contact wall ( 13 ).

Claim (Index 10):
A method for generating haptic feedback in a haptic-feedback-providing touch-interface module comprising a touch surface that is able to detect a press of a user, and at least one actuator as claimed in  claim 1 , the method comprising:\n supplying the electromagnet with current in a first predefined bias direction so as to separate the movable core from the contact wall of the chassis against the force of said elastic element; and supplying the electromagnet with current in a second predefined bias direction that is opposite the first bias direction so that the direction of the current and thus the magnetic field is inverted in order to propel the movable core in the direction of the contact wall of the chassis and in order to maintain the movable core in abutment against this contact wall.
