Apparatus, systems and methods for mitigating vibration of an electronic device

摘要

According to one aspect, an electronic device that includes a vibrating element adapted to vibrate the electronic device, at least one sensor operable to detect the presence of an audible higher-order harmonic above a fundamental frequency when the vibrating element is active. The device also includes a processor operable to adjust the vibrating element to reduce the audible higher-order harmonic when the audible higher-order harmonic is detected.
