    • A content reproduction system uses a first reproducer and a second reproducer to respectively reproduce corresponding first content information and second content information, which are to be played back at a synchronized timing. A first delay amount specification module of the first reproducer obtains a first base delay amount corresponding to a reproduction timing of the first content information and a first additional delay amount set in a first delay processor of the first reproducer. The first delay amount specification module also receives a second base delay amount corresponding to a reproduction timing of the second content information and a second additional delay amount set in a second delay processor of the second reproducer, which are notified by a second delay amount specification module of the second reproducer. The first delay amount specification module updates the first additional delay amount and the second additional delay amount to make a second reproduction delay amount specified according to the second base delay amount and the second additional delay amount consistent with a first reproduction delay amount specified according to the first base delay amount and the first additional delay amount. The first delay amount specification module sets the updated first additional delay amount in the first delay processor, while giving an instruction to the second delay amount specification module to set the updated second additional delay amount in the second delay processor. This arrangement desirably reduces a potential time difference between a reproduction timing of the first content information by the first reproducer and a reproduction timing of the second content information by the second reproducer.
    • 内容再现系统使用第一再现器和第二再现器来分别再现在同步定时中要再现的对应的第一内容信息和第二内容信息。 第一再现器的第一延迟量指定模块获得对应于第一内容信息的再现定时的第一基本延迟量和设置在第一再现器的第一延迟处理器中的第一附加延迟量。 第一延迟量指定模块还接收与第二内容信息的再现定时相对应的第二基本延迟量,以及第二延迟量指定模块通知的设置在第二再现器的第二延迟处理器中的第二附加延迟量 的第二个再现器。 第一延迟量指定模块更新第一附加延迟量和第二附加延迟量,以使得根据第二基本延迟量指定的第二再现延迟量和与根据第二延迟量指定的第一再现延迟量一致的第二附加延迟量 第一基本延迟量和第一附加延迟量。 第一延迟量指定模块在第一延迟处理器中设置更新的第一附加延迟量,同时向第二延迟量指定模块指示在第二延迟处理器中设置更新的第二附加延迟量。 这种布置理想地减少第一再现器的第一内容信息的再现定时与第二再现器之间的第二内容信息的再现定时之间的潜在时间差。

    • An active noise control system is capable of canceling out noise in the passenger compartment of a vehicle based on low-frequency road noise. The active noise control system has a feed-forward control unit for being supplied with reference signals highly correlated to noise from a noise source and generating a noise cancellation signal which is out of phase to noise in the passenger compartment of the vehicle, and a canceling sound generating unit disposed in the passenger compartment for generating a noise canceling sound in response to the noise cancellation signal from said feed-forward control unit. The active noise control system also has microphones for generating reference signals which are positioned respectively near the base of the front seat, near the center of a roof, and within a trunk compartment, i.e., respectively at vibrational antinodes of a primary or secondary acoustic normal mode of the passenger compartment in the longitudinal direction thereof. Output signals from the microphones are supplied as the reference signals.
    • 主动噪声控制系统能够基于低频道路噪声消除车辆乘客舱内的噪声。 主动噪声控制系统具有前馈控制单元,用于提供与来自噪声源的噪声高度相关的参考信号,并产生噪声消除信号,该噪声消除信号在车辆的乘客舱中相位相差,并且取消 发声单元,其布置在所述乘客室中,用于响应于来自所述前馈控制单元的噪声消除信号产生噪声消除声音。 主动噪声控制系统还具有用于产生参考信号的麦克风,其分别位于靠近车顶中心的底座附近,并且在行李箱内,即分别位于初级或次级声学正常的振动波腹处 乘客舱的纵向的模式。 来自麦克风的输出信号作为参考信号提供。
