    • An active vibratory noise control apparatus has a speaker (43; 43-1) driven by an amplifier (42; 42-1) for canceling vibratory noise in the passenger compartment of a vehicle, the speaker being used as a speaker of one of different audio devices (40; 60) that can be installed on the vehicle. Each of the audio devices has a command key switch assembly (45). When the command key switch assembly (45) is operated to turn off transistor (47), a control signal is applied to a switching control circuit (7) in an active vibratory noise control unit (30-1), which identifies the audio device installed on the vehicle. The active vibratory noise control unit (30-1) generates a canceling signal matching characteristics of the speaker (43; 43-1) and / or amplifier (42; 42-1)of the identified audio device for canceling vibratory noise in the passenger compartment.
    • 主动振动噪声控制装置具有由放大器(42; 42-1)驱动的用于消除车辆乘客室中的振动噪声的扬声器(43; 43-1),所述扬声器用作不同的扬声器 可安装在车辆上的音频设备(40; 60)。 每个音频设备具有命令键开关组件(45)。 当命令键开关组件(45)操作以关闭晶体管(47)时,控制信号被施加到主动振动噪声控制单元(30-1)中的开关控制电路(7),该主动振动噪声控制单元识别音频设备 安装在车上。 主动振动噪声控制单元(30-1)产生用于消除乘客中的振动噪声的识别的音频设备的扬声器(43; 43-1)和/或放大器(42; 42-1)的抵消信号匹配特性 车厢。
