Calibration of Haptic Devices

A haptic output device comprising:

• a feedback surface;
• an actuator;
• one or more biasing supports;
• and
• a controller operatively coupled to the actuator, wherein the controller is configured to:
• obtain one or more characteristics of an input waveform;
• determine a current profile associated with the input waveform, wherein the current profile includes a scaling factor associated with a stiffness of the one or more biasing supports;
• and
• combining the input waveform with the scaling factor to generate an output waveform that is substantially similar to the input waveform.

A method for providing tactile output and audio output on haptic device for an electronic device, the method comprising:

• receiving a profile of a desired output waveform to be provided by a haptic device;
• generating an input waveform based on the desired output waveform;
• adding an audio waveform on the input waveform;
• and
• providing the input waveform having the audio waveform to the haptic device to generate the tactile output and the audio output.
