摘要： An optical fiber connector is comprised of an optical cable and a pair of plugs connected to input and output end portions of the optical cable. A multi-fiber core employed in the optical fiber cable is constituted by a plurality of fiber cores. The input and output end portions of the optical cable are bent at an angle of about 90 while having a bent radius at the bent top portion.

摘要： The present invention relates to a so-called bass-reflex electroacoustic transducing apparatus, wherein a plurality of sound ducts (ports) having the same equivalent mass and different lengths are provided in communication with a housing which incorporates therein an electroacoustic transducing element. Thus, resonance and antiresonance generated in respective sound ducts cancel each other out, thereby preventing a tone quality of a reproduced sound from being deteriorated.
摘要翻译：本发明涉及一种所谓的低音反射电声换能装置，其中具有相同等效质量和不同长度的多个声音导管（端口）设置成与其中结合有电声换能元件的壳体连通。因此，各声道中产生的共振和反谐振相互抵消，从而防止再现声音的音质劣化。

摘要： A speaker apparatus includes a yoke formed of a magnetic material and having a flange portion and a center pole protruded integrally forwards from a mid portion of the flange portion, and a ring-shaped driving magnet into which the center pole is inserted. The speaker apparatus also includes a top plate mounted on the driving magnet. The top plate is formed of a magnetic material and the center pole is inserted through the top plate. The top plate defines a magnetic gap together with the center pole. The speaker apparatus further includes a voice coil mounted on a bobbin secured to a diaphragm in the magnetic gap, and a canceling magnet arranged on the outer periphery of and spaced from the driving magnet at a pre-set spacing for covering the driving magnet. The canceling magnet cancels the magnetic flux leaking to outside a magnetic circuit including the driving magnet.
摘要翻译：扬声器装置包括由磁性材料形成的磁轭，其具有凸缘部分和从凸缘部分的中间部分一体地突出的中心磁极，以及环形驱动磁体，中心极插入该磁体中。扬声器装置还包括安装在驱动磁体上的顶板。顶板由磁性材料形成，中心柱通过顶板插入。顶板与中心极一起限定磁隙。扬声器装置还包括安装在固定到磁隙中的隔膜的线轴上的音圈，以及以预定间隔布置在驱动磁体的外周并与驱动磁体隔开的取消磁体，用于覆盖驱动磁体。取消磁体抵消泄漏到包括驱动磁体的磁路外部的磁通量。
