Abstract
A portable electronic device provides adaptive vibration noise reduction by generating a user alert vibration that is one of a first magnitude and a second magnitude, with the first magnitude being greater than the second magnitude. The portable device is configured to alert the user by providing a first magnitude alert vibration except when the device is lying flat and ambient noise at the device is low, and to provide a second magnitude alert vibration when the device is lying flat and ambient noise at the device is low.
