An active dynamic anti‐vibration/noise suppressing control subsystem to enable lighter and
thinner notebook computer to produce higher performance with low noise level.
Microcontroller intelligent algorithm autonomously control close loop monitoring vibration
sensors and exciting of vibration devices, e.g. Piezoelectric or Linear Resonant Actuator to
continuously mitigate vibration/noise level. The lower system vibration/noise floor allows
enabling faster fan speed and higher efficiency power profile to produce higher overall
performance and improve user experience with system noise under increased system
