Abstract:
Described herein are system and method embodiments of acoustic augmentation of haptic vibration with correlated sounds. Embodiments of a haptic driven signal crossing both vibration band and acoustic band are disclosed. The driven signal at the acoustic band enables a haptic in an electronic device to provide an audio augmentation for haptic vibration independent from a loudspeaker of the electronic device. Upon a touch on a touch surface is detected, a vibration request is generated based on the touch and user preferences. A pattern generator is used to generate a vibration signal based on the vibration request to drive a haptic vibrator for desired vibration and acoustic sound patterns.
