Piezoelectric haptic actuator integration

摘要

User interface experiences with electronic devices are enhanced with feedback cues such as haptic or vibrotactile output feedback. One or more piezoelectric actuators generate haptic output. The one or more piezoelectric actuators may be integrated onto a display substrate, a battery case, a device enclosure, or other component. Such integration may improve propagation of the haptic output to the user, reduce bulk of the electronic device, minimize parts count, and reduce production costs.
