1. A device for providing a haptic effect, comprising:
a substrate layer having a first side and a second side, wherein the second side of the substrate layer comprises at least one depression;
a touch-interface surface on the first side of the substrate layer;
at least one piezoelectric transducer on the second side of the substrate layer comprising a support plate and a piezoelectric element, wherein the at least one piezoelectric transducer is aligned with the at least one depression of the substrate layer in a plane of the substrate layer; and
a printed circuit board layer, later PCB layer, electrically coupled to the piezoelectric element of the piezoelectric transducer;
wherein the support plate is in contact with the second side of the substrate layer and the piezoelectric element is located on a different side of the support plate than the substrate layer.
