Mutamorphic haptic substrate

Substrates for components such as a display, touch sensor, multifunction stackup, and so forth may incorporate one or more haptic actuators configured to generate haptic output. These actuators may be formed from a portion of a body of the substrate, or separate pieces bonded or otherwise affixed to the substrate. Audible output resulting from activation of the actuators may be minimized by coupling the actuators such that they produce a physical displacement of the body of the substrate within, rather than orthogonal to, the plane of the body of the substrate.
