技术领域 本发明涉及 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。 背景技术 常用的耳塞机， 如手机上配带的耳塞机， 包括插头、 导线和耳塞头， 耳塞头内装微 型扬声器。 由于直接使用手机接打电话， 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磁 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受到诸如超高频磁场之类的辐射线通过耳塞头传送到耳 朵内部直至大脑的危险。 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。
已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， 但由于其声波通道太短： 仅为： 5-10cm， 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、 美国工程院院士、 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防电磁辐射的要求， 同时也没有音腔， 因此， 频率 响应不好； 本发明人申请的申请号为： 200610028981. 6， 名称为： 安全耳塞机的申请文 件， 也公开了安全耳塞机， 该申请虽然公开了声波传输通道， 但没公开其中的声波通道 的具体长度， 本发明人接着申请的中国专利， 公开号为 CN101227756A，公开日 2008年 7 月 23 日， 发明创造名称为： 安全耳塞机， 该申请案虽然公开了声波通道的具体长度， 但是， 其不足之处是没有公开声波集中口， 分路通道， 扬声器的密封， 开关和声波传输 通道的紧固。

1， 本发明的耳塞机是在本申请人于 2008年申请的申请号为： 200810000676. 5， 发 明名称为：一种耳塞机的基础上， 进一步发明的， 因此， 具有该上一个申请的所有优点： 例如： 由于加长了声波传输通道， 使辐射到人耳朵的辐射强度达到手机发明人施敏教授 提出的 2mG或 2 mG以下， 例如能达到 1. 8 mG 或 1. 8 mG以下的要求， 真正避免电磁辐 射对人大脑和对人体的损害；
2， 由于在主体内增设了密封小盒， 扬声器和声波集中口及声波通道口三者的连接 处被一起密封在密封小盒内， 由于， 在扬声器和声波通道之间增设了声波集中口， 大大 地提高了高频段和低频段的频率响应， 使失真极少， 相反， 如果没有声波集中口，那么， 高频段和低频段衰减均很大， 几乎没有功率输出， 会造成严重的失真；
3， 本发明增加了扬声器密封小盒， 密封了扬声器所产生的声音的声波， 使声波全 部通过声波集中口， 并全部顺利地传送到声波通道， 而且由于扬声器被密封在扬声器密 封小盒内， 话筒安装在主体上的一个圆孔里， 话筒受音面向外并且周边密封， 使声音仅 能先通过主体上的受话孔（可以是一个或多个）， 再通过话筒受音面前面的受音小孔（可 以是一个或多个）， 进而传送到话筒。 因此， 消除了扬声器对话筒的干扰， 使话筒中不 会产生干扰的回音或噪音， 因扬声器和话筒都装在主体内。
4， 本发明增加了一个声波集中口， 使频率响应得到改善， 因为， 所述微型扬声器 所产生的声波， 由声波集中口即倒喇叭口或去除了头部的锥体（它的形状）， 进行集中， 送到声波通道， 再送到人的耳朵中， 这个过程使得频率响应得到改善；
5， 再者， 在主体内增加了一个开关， 由于该开关可以在手机接通瞬间信号最强的 时间， 使手机远离人体操作， 达到了最大防辐射效果， 有效地防止了辐射对人体的大脑 和人体其他器官的损伤；
6， 而且一个喇叭可供 1 个人的两个耳朵听， 产生了立体声感觉， 或两个人各听一 个耳塞， 降低了成本， 尤其适合于广大年轻人使用；
7， 另外， 如果与已有技术使用 2个扬声器比较， 由于本发明其中有一款仅使用一 个扬声器， 因此， 使壳体的体积变小， 同时， 当仅使用一个扬声器时， 可以选用直径大 的扬声器， 扬声器直径增大后， 低频响应较好， 同时可降低成本；
8， 由于使用了以上所述的两种紧固方式， 大大提高了该耳塞机的抗拉力强度或拉 力强度， 使该拉力强度达到 2公斤或 2公斤以上。
