Description

一种弹性耳机线的制备方法及制品 技术领域
本发明涉及电线电缆技术领域，具体涉及一种弹性耳机线的制备方法及制品。
背景技术
普通的导线是一般是由金属导线构成，但其反复弯曲性能较差，也较低，不能满足一些动态场合的使用。例如中国专利申请号200620090447.3《可伸缩电线、电缆》、和申请号86203746《弹性导线和电缆》揭示了两种具有伸缩性的导线，其共同点是均由导线中心是橡胶条和缠绕在橡胶条上的导体构成，优点是具有一定的伸缩性，但金属导体不可避免的会有金属疲劳问题，一旦反复伸缩弯曲就会导致金属导体的断裂，所以，上述两种产品在实际使用中仍会存在比较严重的使用寿命短的问题。
发明内容
本发明的目的是针对上述不足，提供一种弹性耳机线的制备方法及制品，本发明的制备方法将漆包线编织成弹性伸缩网管，从而制得的耳机线产品能够具备优良的伸缩性和较长的伸缩长度，并提高耳机线的使用寿命及使用效果。
