1. A method of producing haptic effects, the method comprising:

  • outputting a plurality of audio effects by a plurality of actuators, each actuator of the plurality of actuators being located in a different region of a device, wherein a first audio effect of the plurality of audio effects is output from a surface of the device by a first actuator of the plurality of actuators and a second audio effect is output from the surface of the device by a second actuator of the plurality of actuators;

    generating a first haptic effect based on the first audio effect bydetermining a set of values of audio characteristics of an audio signal corresponding to the first audio effect, the set of values of audio characteristics being generated from an audio data frame and comprising at least one of an amplitude of the audio data frame, a frequency of the audio data frame, and a duration of the audio data frame,mapping the set of values of audio characteristics to the first actuator,generating a haptic signal based on the set of values of audio characteristics, wherein the first haptic signal corresponds to the first haptic effect; and

    outputting the first haptic effect by the first actuator bysending the haptic signal to the first actuator based on the mapping of the set of values of audio characteristics to the first actuator, andplaying the haptic signal at the first actuator to generate the first haptic effect.
