Title: HAPTIC DRIVER WITH ATTENUATION
Abstract:
In each of the various embodiments, a haptic driver is configured to attenuate a drive signal of an actuator. In particular, the haptic drivers described herein are configured to identify the resonance frequency of the actuator and to attenuate the haptic drive signal within a range of frequencies, the range being based on the identified resonance frequency. As a result, the strength of haptic effects produced by the actuator may be more uniform along a wider frequency range.
