The invention relates to a microphone system (2) for a motor vehicle (1), comprising a first, second and third microphone (11, 12, 13) and a signal-processing device (4), which is designed to processrespective signals provided by the microphones (11, 12, 13), the signal-processing device (4) being designed to process the signals of the first and second microphones (11, 12) in such a way that a driver directivity pattern (A1) oriented toward a position of a driver seat (7) is provided, or to process the signals of the second and third microphones (12, 13) in such a way that a front passenger directivity pattern (B1) oriented toward a position of a front passenger seat (8) is provided, and to provide a driver interfering-noise directivity pattern (AS1) by processing the signals of two microphones together, and to further process a driver useful signal associated with the driver directivity pattern (A1) in accordance with a driver interference signal associated with the driver interfering-noise directivity pattern (AS1), or to provide a front passenger interfering-noise directivity pattern (BS1) by processing the signals of two microphones together, and to further process a front passenger useful signal associated with the front passenger directivity pattern (B1) in accordance with a front passenger interference signal associated with the front passenger interfering-noise directivity pattern (BS1), in order to improve the quality of the useful signal in question.

    本发明涉及用于机动车(1)的麦克风系统(2),包括第一、第二和第三麦克风(11、12、13)和信号处理装置(4),其设计成,处理相应的由麦克风(11、12、13)提供的信号;信号处理装置(4)设计成,如此处理第一和第二麦克风(11、12)的信号,使得提供朝向驾驶员座位(7)的位置的驾驶员方向特性(A1);或者如此处理第二和第三麦克风(12、13)的信号,使得提供朝向副驾驶员座位(8)的位置的副驾驶员方向特性(B1);以及提供驾驶员‑干扰声‑方向特性(AS1),其方法是共同处理两个麦克风的信号;以及根据对应于驾驶员‑干扰声‑方向特性(AS1)的驾驶员干扰信号再处理对应于驾驶员方向特性(A1)的驾驶员有用信号;或者提供副驾驶员‑干扰声‑方向特性(BS1),其方法是共同处理两个麦克风的信号;以及根据对应于副驾驶员‑干扰声‑方向特性(BS1)的副驾驶员干扰信号再处理对应于副驾驶员方向特性(B1)的副驾驶员有用信号,以改善相应的有用信号的质量。
