Disclosed herein are methods and systems for providing haptic output and audio output on computing devices using the same haptic device and methods for calibrating the same. To produce the haptic and audio output, the computing device receives a profile of a desired output waveform that is to be provided by the haptic device. Using the desired output waveform, an input waveform is generated. Once the input waveform that will produce the desired output waveform is generated, the input waveform may be calibrated to account for various structural components of the haptic device and may also be combined with an audio waveform. The input waveform is then provided to the haptic device.
