Реферат: A trackpad includes: a substrate; a circuit board coupled to the substrate for detecting a position of an object adjacent the substrate; a haptic feedback component coupled to the circuit board; a first plate coupled to the circuit board; a second plate including a spring element, a spacer coupling the circuit board and the spring element to each other, the spring element facilitating first movement of the substrate, the circuit board and the first plate relative to the second plate, the spacer facilitating second movement of at least the substrate and the circuit board by the haptic feedback component; and a capacitive force sensor that detects a capacitance of the first plate and the second plate. A trackpad can include a circuit board coupled to the substrate and including the first plate.
