An active noise attenuation system for an air induction assembly includes a housing
that is mounted to a vehicle structure and a speaker assembly that is mounted within
the housing to generate a sound field for attenuating noise. The housing defines
an air inlet duct open end through which air is drawn. A microphone detects noise
and modifies an anti-noise signal that is sent from an electronics center. The
electronics center receives the signal, mixes with other engine signals, phase-shifts
the signal, and sends the phase-shifted signal to the speaker to attenuate the
noise. The speaker includes electrical connections that extend outwardly toward
the air inlet duct open end for connection to the electronics center. The microphone
and speaker are connected to the electronics center with flex cables.
