摘要： The disclosure describes improved apparatus for adjusting a unidirectional microphone in order to reduce the electrical output due to mechanical shocks applied to the microphone casing. The microphone includes a diaphragm supported by a housing which is resiliently mounted on the casing. The adjustment apparatus includes a mounting diaphragm positioned between the outer casing and the housing, and an enclosed chamber provided with an air leak which can alter the compliance and resistance of the mounting diaphragm in a controlled manner. A method of balancing the size or value of the elements of the microphone to provide pneumatic shock cancellation is also described.
摘要翻译：本公开描述了用于调节单向麦克风的改进的装置，以便由于施加到麦克风壳体的机械冲击而减少电输出。麦克风包括由壳体支撑的隔膜，壳体弹性地安装在壳体上。调节装置包括位于外壳和壳体之间的安装隔膜，以及设置有空气泄漏的封闭室，其可以以受控的方式改变安装隔膜的顺应性和电阻。还描述了平衡麦克风的元件的尺寸或值以提供气动冲击抵消的方法。
