ACTUATOR FOR A TACTILE INTERFACE MODULE WITH HAPTIC FEEDBACK
First Claim
1. An actuator for a touch interface module with haptic feedback, intended to be linked to a touch surface suitable for detecting a contact by a user, and suitable for generating a haptic feedback as a function of a detected contact and comprising:
- a frame;
a mobile core cooperating with the frame, configured to be driven in movement between extreme positions to generate the haptic feedback;
electromagnetic actuation means for driving the mobile core in movement;
fixing elements, intended to link the actuator to the touch surface; and
elastic means defining a rest position of the mobile core in the absence of driving by the actuation means,wherein the elastic means are arranged around said fixing elements.

Abstract
The invention relates to an actuator for a tactile interface module (1) with haptic feedback, to be connected to a tactile surface (3) that can detect pressure by a user and can generate haptic feedback according to a detected pressure, and comprising: a frame (11); a mobile core (13) cooperating with the frame (11), to be movably driven between end positions in order to generate the haptic feedback; electromagnetic actuating means (15, 17) for movably driving the mobile core (13); fixing elements (23) for connecting the actuator to the tactile surface (3); and elastic means (21) defining an idle position of the mobile core (13) in the absence of the actuating means (15, 17) driving the core, characterised in that the elastic means (21) are arranged around the fixing elements (23).
