    • A method and apparatus for increasing phase margin in a feedback circuit of an active noise reduction headphone. The method includes providing an acoustic block comprising an acoustic driver comprising a voice coil mechanically coupled along an attachment line to an acoustic energy radiating diaphragm, the acoustic block further comprising a microphone positioned along a line parallel to an intended direction of vibration of the acoustic diaphragm and intersecting the attachment line, the acoustic block characterized by a magnitude frequency response compensating the magnitude frequency response by a compensation pattern that has a positive slope over at least one spectral range above 10 kHz.
    • 一种用于增加有源降噪耳机的反馈电路中的相位裕度的方法和装置。 该方法包括提供声学块,其包括声学驱动器,声学驱动器包括沿着附着线机械耦合到声能辐射光阑的音圈,所述声学块还包括麦克风,所述麦克风沿着平行于所述声学振动膜的预期振动方向的线定位 并且与连接线相交,声学块的特征在于通过在10kHz以上的至少一个光谱范围内具有正斜率的补偿图案来补偿幅度频率响应的幅度频率响应。

    • An in-the-ear earphone which is placed on a user's ear including a cushion and a shell body defining an internal cavity. The shell body has an extended portion shaped and sized to fit into a concha of the user's ear. The extended portion includes an aperture at an end thereof which aligns with the user's ear when the earphone is being worn by the user. The extended portion defines a passageway extending from the aperture to the internal cavity. The cushion covers at least part of the extended portion of the shell body and has an opening aligned with the aperture.
