Description

一种高屏蔽实用性耳机线
技术领域
本发明涉及一种高屏蔽实用性耳机线。
背景技术
信号在传输的过程中,如果传输路径上的特性阻抗发生变化,信号就会在阻抗不连续的结点产生反射,造成信号失真。因原有技术采用电信号,现有的技术越来越多的采用模拟信号,现有技术的音频线缆一般采用不具备屏蔽层的普通线缆,在高电压或高磁性的场所使用普通音频线缆时,会出现杂音,使得语音通话会严重受到干扰。
再者,为了方便携带使用,音频线缆需要频繁将其收纳和展开,由于不断反复的拉伸,现有技术中的音频线缆非常容易损坏,使用寿命低。
发明内容
为了解决以上所述的技术问题,本发明提供以下技术方案:
一种高屏蔽实用性耳机线,用于音频信号传输,包括多组音频信号传输单元,每组音频信号单元由多股绞合线(1)、屏蔽层、中被层(4)依次组成,所述多股绞合线为同轴线结构,所述屏蔽层由内层(2)和外层(3)构成,内层为铝箔、铜箔、锡纸的任一一种,外层为编织或缠绕在所述内层外侧的金属丝,所述屏蔽层的外侧包裹有由聚醚酮制成的中被层,多组所述音频信号传输单元由外被层(5)包裹。同轴线的结构,能有效传输模拟信号,致使信号不会在此结构中造成信号完全失真。
进一步,所述外被层为热塑性弹性体材质,使得耳机线具有良好的弹力,从而保护产品寿命较之一般PVC产品的寿命更长
进一步,所述音频信号传输单元为四组,四组音频信号传输单元的截面成正方形排列。
进一步,在四组音频信号传输单元的中央设有防弹丝(6),所述防弹丝为芳纶丝。
相比于现有技术,本发明的有益效果为:
1、增加了屏蔽层,屏蔽层为导电金属材质,不但可以保证线材产生稳定的特性阻抗,保证了信号传输的稳定性,还可以提高线材的抗拉性,同时还可以作为排流线使用;同轴线的结构,能有效传输模拟信号,致使信号不会在此结构中造成信号完全失真;
2、中被层由聚醚酮制成,使得线缆有很好的耐高温性能,拉伸性能,增加了电缆的寿命;
3、防弹丝的设置,使得耳机线具备了防弹特性;
4、新型结构的应用,使得耳机线数据不仅仅可以传输电信号,还可以传输模拟信号。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解,这些附图未必是按比例绘制的。附图中:
图1为本发明的整体结构示意图。
具体实施方式
如图1所示,一种高屏蔽实用性耳机线,用于音频信号传输,包括多组音频信号传输单元,每组音频信号单元由多股绞合线、屏蔽层、中被层依次组成,所述屏蔽层设在所述多股绞合线的外侧,所述屏蔽层由内层2和外层3构成,内层为铝箔、铜箔、锡纸的任一一种,外层为编织或缠绕在所述内层外侧的金属丝,增加了屏蔽层,屏蔽层为导电金属材质,不但可以保证线材产生稳定的线性阻抗,保证了信号传输的稳定性,还可以提高线材的抗拉性,同时还可以作为排流线使用。所述屏蔽层的外侧包裹有由聚醚酮制成的中被层,多组所述音频信号传输单元由外被层5包裹。所述外被层为热塑性弹性体材质。所述多股绞合线为同轴线结构。同轴线的结构,能有效传输模拟信号,致使信号不会在此结构中造成信号完全失真。
所述音频信号传输单元为四组,四组音频信号传输单元的截面成正方形排列。中被层由聚醚酮制成,使得线缆有很好的耐高温性能,拉伸性能,增加了电缆的寿命。
在四组音频信号传输单元的中央设有防弹丝6,所述防弹丝为芳纶丝。防弹丝的设置,使得耳机线具备了防弹特性。
至此,本领域技术人员应认识到,虽然本文已详尽示出和描述了本发明的多个示例性实施例,但是,在不脱离本发明精神和范围的情况下,仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此,本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
