Description

安全的耳机
  技术领域
   本发明涉及到一种防辐射或安全耳塞机,更具体地说,涉及到一种用于手机等高频磁场等辐射较强的通信设备的防辐射耳塞机和立体声防辐射耳塞机,尤其涉及到一种频率响应得到真正改善的,而且能产生更好的立体声效果的耳塞机,比传统的线控耳机的频率响应还要好。
背景技术
常用的耳塞机,如手机或其它通信设备上配带的耳塞机,包括插头、导线和耳塞头,耳塞头内装微型扬声器。由于直接用手机接打电话,手机所产生的超高频磁场等有害辐射线会严重刺激人的大脑神经,影响人的身体健康,人们往往使用耳塞机接打手机以减少超高频词场以及电波、热能等多种辐射线对人体大脑的损害。但是,使用耳塞头内直接安装扬声器的普通耳塞机仍然不能避免收到诸如超高频词场之类的辐射线通过耳塞头传送到耳朵内部直接危害大脑的危险。另外,这种内装扬声器的耳塞头本身带有的高1600高斯的永久性磁体磁场同样对人体大脑也会造成损伤。因此,长时间、高频次的使用手机或此类耳塞机都容易产生头痛、头晕、头麻等症状。
 有技术的防电磁辐射的耳机,如专利号为:ZL02244828.4,名称为:无辐射耳机,虽然能减少电磁辐射,但由于其一仅有5-10cm的声波通道,其二没有设置金属屏蔽隔离线所以达不到2mG(毫高斯,以下同)或2mG以下的要求,而控制在2mG或2mG 以下,是由于磁场对人体有伤害,手机发明人美国斯坦福大学博士、美国工程院博士、台湾交通大学施敏教授提出的要求。因此,已有技术的耳机满足不了上述电磁辐射的要求,同时也没有音腔等。因此,频率响应不好;本发明人申请的专利号为:200810167226.5,名称为:安全耳塞机的申请文件,也公开了安全耳塞机的五项发明,公开了实现防辐射的办法和提高音质的方法,已获得了世界九个国家的专利,但是该专利的音质没超越传统耳机的,本申请就是公开了音质超越传统的耳机而且能再提高防辐射的效果,达到无辐射的效果。
技术问题
综上所述,人们非常需要有一种真正能够高性能防止电磁辐射和频率响应比传统耳机更好的耳塞机,一种频率响应得到真正改善的耳塞机,一种具有无辐射、更好的立体声效果的耳塞机。
技术解决方案
本发明涉及安全的耳机,主要包括线控式的安全耳机和头戴式的安全耳机,采用了不同频响的多个扬声器分别供二个耳朵听,所以频率响应特别好,比传统的耳机还要好,而且设置了降噪声特殊方案,更重要是设置了降噪音频信号转换系统,有效地将有源降噪音频信号的传输转换为无源音频信号的传输,又恢复到有源音频信号的传输使空气导管无源的信号传输可置于1000mm长度,因为设置了金属屏蔽隔离线所以使人体长距离隔绝通信机的辐射,但话筒还是和发音口保持很近的距离,从而达到了良好地降噪又达到高度地防辐射效果并且具有高音质,并解决了现有防辐射耳机话筒必须要置在空气导管之外的技术问题,因为话筒离远了话筒的效果就差了,声音还小。
所以这项发明确实是既高强度地防辐射又高音质还防噪声的优良的安全的耳机。
