Multi-modal haptic feedback for an electronic device using a single haptic actuator

摘要

Systems, methods, and computer-readable media provide multiple modes of haptic feedback for an electronic device using a single haptic actuator. Adjusting a parameter (e.g., frequency) of an actuator waveform generated by the single haptic actuator may affect how a mechanical coupling between the haptic actuator and a portion of the electronic device produces a device waveform at that device portion from the actuator waveform. A first mechanical coupling with a first response characteristic (e.g., stiffness or resonance frequency) may be provided between the haptic actuator and a first portion of the electronic device (e.g., a user input component of the electronic device), while a second mechanical coupling with a different second response characteristic may be provided between the haptic actuator and a second portion of the electronic device (e.g., the device housing of the electronic device) to selectively provide localized haptic feedback at the first portion of the electronic device.
