1. An electronic device comprising:
- a device housing;
a haptic actuator carried by the device housing;
an audio input transducer carried by the device housing;
an audio output transducer carried by the device housing; and
a controller carried by the device housing and configured todrive the haptic actuator,determine a sound level of the haptic actuator using the audio input transducer, anddrive the audio output transducer based upon the determined sound level with an offsetting sound level so that the haptic actuator operates within a desired sound level range.

Abstract
An electronic device may include a device housing, a haptic actuator carried by the device housing, and an audio input transducer carried by the device housing. The electronic device may also include a controller coupled to the audio input transducer and the haptic actuator. The controller may be capable of determining a sound level of the haptic actuator, attempting to drive the haptic actuator to operate within a desired sound level range, and when unable to drive the haptic actuator within the desired sound level range, then generating a warning indication.
