    • A miniature audio earphone includes a pair of audio earphones, an electrical connector adapted for making a selectively detachable physical and electrical connection to a source of stereo audio signals, a generally Y-shaped electrical lead assembly having a bifurcated upper portion and an adjoining lower portion, whose lower end is coupled to the connector. The upper portion has a pair of branch leads each of which is coupled to a respective one of said earphones. A plurality of exteriorly disposed mechanical shielding elements at least partially surrounds an underlying portion of at least one of said branch leads to resist damage to the lead assembly due to abrasion, crushing, kinking and cutting without unduly impairing the flexibility of the assembly or causing it to have an unattractive appearance. A tensile stress-relief line is also provided for resisting damage to the upper portion of the assembly due to tension.
    • 一个微型音频耳机包括一对音频耳机,一个电连接器,适于与一个立体声音频信号源进行有选择地可拆卸的物理和电气连接,一个大体为Y形的电线组件,其具有分叉的上部和相邻的下部 ,其下端连接到连接器。 上部具有一对分支引线,每个分支引线联接到相应的一个所述耳机。 多个外部设置的机械屏蔽元件至少部分地围绕至少一个所述分支引线的下部部分,以抵抗由于磨损,破碎,扭结和切割而导致的引线组件的损坏,而不会不适当地损害组件的柔性或引起它 具有不吸引人的外观。 还提供拉伸应力消除线,用于抵抗由于张力而对组件的上部的损坏。
