摘要： A communication or computing device comprises a main body (150) and a stylus (110) for interfacing with the main body, wherein the stylus (110) includes a microphone. the microphone is a directional microphone (111, 112, 113) for receiving sounds (101) from a user of the stylus (110), to provide audio input to the device. For a small device operable via a stylus at arm's length from the user, the invention provides higher quality speech input and improved dual (tactile and speech input) modes of operation over existing built-in microphones. The benefits primarily result from the use of a directional microphone positioned with the stylus. The directional microphone may take the form of a microphone array.
摘要翻译：通信或计算设备包括用于与主体对接的主体（150）和触笔（110），其中触笔（110）包括麦克风。麦克风是用于从触控笔（110）的用户接收声音（101）的定向麦克风（111,112,113），以向设备提供音频输入。对于通过用户手柄的手写笔操作的小型装置，本发明提供了比现有的内置麦克风更高质量的语音输入和改进的双重（触觉和语音输入）操作模式。这些好处主要是由于使用与触控笔定位的定向麦克风。定向麦克风可以采取麦克风阵列的形式。

摘要： A switched-geometry arrangement and method for processing outputs from microphones (40.1-40.M) by: receiving signals from the microphones at respective inputs; switching (41.1-41.M) the signals received at the inputs between outputs; summing (42.2.1-42.M.N) desired ones of the outputs and performing array processing (43) to produce a switched-geometry output signal. Operating the switches alters the configuration of microphones connected to the array processor (43), and the switching and subsequent processing may be adaptively operated in dependence on the output signal. Performing the switching in analogue circuitry and subsequent processing digitally allows lower cost, size and power consumption than fully digital processing. Most advantage is expected when a large number of microphones (say 50 or more) is connected to a much smaller number of array signal processor inputs, and especially when the analogue switches and adders are integrated into a silicon chip along with a microphone (e.g. MEMS device) array.
摘要翻译：一种用于通过以下步骤处理来自麦克风（40.1-40.M）的输出的开关几何结构和方法：在相应的输入处从麦克风接收信号; 切换（41.1-41.M）在输出端之间输入的信号; 求和（42.2.1-42.M.N）期望的输出和执行阵列处理（43）以产生切换几何输出信号。操作开关改变连接到阵列处理器（43）的麦克风的配置，并且切换和后续处理可以根据输出信号自适应地操作。在数字处理中进行模拟电路和后续处理的切换允许比完全数字处理更低的成本，尺寸和功耗。当大量麦克风（例如50个或更多）连接到更少数量的阵列信号处理器输入端时，尤其是当模拟开关和加法器与麦克风一起集成到硅芯片中（例如MEMS 设备）数组。
