ACTIVE NOISE REDUCTION AND VIBRATION SUPPRESSION SYSTEM Russian patent published in 2019 - IPC G10K11/178 H04B1/00 

FIELD: machine building.

SUBSTANCE: invention relates to automotive electrical equipment. Active noise reduction and active vibration suppression system comprises controller; an audio subsystem with a microphone for noise detection and a speaker for outputting the noise-suppressing sound. There is also a vibration subsystem which includes a vibration sensor and a vibration drive for generating forces. Controller communicates and controls, through a digital network, an audio subsystem and a vibration subsystem. Controller additionally controls through the digital network based on the noise detected by the microphone, the speaker for outputting the noise-suppressing sound and the vibration drive to create a force which generates noise-suppressing sound. Controller communicates with the electronic control unit via the CAN bus so that the controller generates a reference signal proportional to the frequency of the engine rotation cycles.

EFFECT: noise and vibration are suppressed.
