    • 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.
    • 用于空气感应组件的有源噪声衰减系统包括安装到车辆结构的壳体和安装在壳体内的扬声器组件,以产生用于衰减噪声的声场。 壳体限定了空气入口管道开口端,空气通过该开口端被抽出。 麦克风检测噪声并修改从电子中心发送的抗噪声信号。 电子中心接收信号,与其他发动机信号混合,相移信号,并将相移信号发送到扬声器以衰减噪声。 扬声器包括向空气入口导管开口端向外延伸的电连接,用于连接到电子中心。 麦克风和扬声器使用柔性电缆连接到电子中心。
