1. A vibration feedback device, comprising:
a substrate, having a first surface and a second surface, the first surface being a user operation surface, the second surface comprising at least one driving coil, at least one induction coil, a controller and a driver, the controller is electrically connected to the user operation surface, the at least one induction coil, the driver and the at least one driving coil, the at least one induction coil, a controller, and a driver; the driver being electrically connected to the user operation surface, the at least one driving coil, and the at least one induction coil, and the driver, the at last one driving coil and the at least one induction coil being disposed apart from each other;
a frame, disposed opposite to the second surface of the substrate, and comprising a first magnet set corresponding to the at least one driving coil and a second magnet set corresponding to the at least one induction coil disposed corresponding to the second surface of the substrate; and
at least three displacement restoration devices, one end of each displacement restoration device being connected to the frame, and the other end of each displacement restoration device connected to the substrate.
