Abstract
An electronic device comprises a haptic feedback system. The haptic feedback system includes a first haptic actuator coupled to a controller via a first set of two or more electrodes, and a second haptic actuator coupled to the first haptic actuator, and further coupled to the controller via a second set of two or more electrodes. The controller is configured to provide a first drive signal to the first haptic actuator via the first set of two or more electrodes, and to provide a second drive signal, different from the first drive signal, to the second haptic actuator via the second set of two or more electrodes. Combining two haptic actuators allows for a broader range of feedback and a heightened user experience.
