The present disclosure relates to an active haptic feedback device (1) for a human machine interface (100, 200, 300), comprising a fixed part, a moveable part and a vibrating plate, wherein the fixed part comprises a coil winding (10) on a bobbin (11) and through which a coil core (12) extends, which is fixed to a base plate (40); the moveable part comprises a ferromagnetic plate (14) arranged between the coil core (12) and the base plate (40), wherein the ferromagnetic plate (14) has a resting state, when no current is applied to the coil winding (10), with a gap (50) between the ferromagnetic plate (14) and the coil core (12), and an activation state, when current is applied to the coil winding (10), with the gap (50) being reduced due to a movement of the ferromagnetic plate (14) away from the base plate (40) and towards the coil core (12), and the vibrating plate (16) is arranged on the side of the coil core (12) opposite to the side of the ferromagnetic plate (14) such that the coil core (12) is extending at least partly between the vibrating plate (16) and the ferromagnetic plate (14), wherein the vibrating plate (16) is fixedly attached to the ferromagnetic plate (14) and moveably attached to the base plate (40) via spring means (18, 19), wherein the spring means (18, 19) are configured to bring back the ferromagnetic plate (14) to its resting position when no current is applied to the coil winding (10), from its activation position. It also relates to a human machine interface with at least one such device, and an automotive part with at least one such human machine interface.
