对附图的简要说明
附图说明
[0015] 图 1及图 2为本申请实施例中， 带有骨传导耳机的眼镜的整体示意图；
[0016] 图 2为本申请实施例中， 骨传导耳机的放大图；
[0017] 图 3为本申请实施例中， 骨传导耳机的局部剖视图。
本发明的实施方式
[0018] 具体实施方式 [0019] 下面通过具体实施方式结合附图对本申请作进一步详细说明。
[0020] 本实施例所提供的带有骨传导耳机的眼镜， 如图 1-图 3所示， 该眼镜包括： 镜 框 1及镜腿 2， 镜腿 2的内侧镶嵌有骨传导耳机。 骨传导耳机包括主机 3， 主机 3的 振动面 31朝向镜腿 2的内侧。 该眼镜穿戴吋， 镜腿 2将振动面 31压向使用者的耳 朵附近的皮肤表面， 通过颅骨向听觉器官传递机械振动， 从而使得使用者的听 觉神经获得声音信息。 该主机 3的振动面 31外缘处设有一圈密封边 32， 密封边 32 向垂直于振动面 31的方向延伸。 该密封边 32由具有较好弹性的硅胶薄片制备， 硅胶薄片反复弯折， 使得密封边 32整体呈界面半径不断收缩释放往复变化的减 震状， 当密封边 32受到挤压后， 会沿着弯折的折边堆叠收缩， 使得被密封边 32 环饶的振动面 31与头使用者部皮肤紧密贴合。 其中， 密封边 32的弯折处截面呈 波浪状， 也可以是 W形或 V形。 为确保振动面 31与人体头部皮肤贴合的紧密， 密 封边 32压缩后， 其厚度以不凸出振动面 32之外为准。 因此， 本实施例中， 密封 边 32的根部固定在与振动面 31相间隔一定距离处， 使得密封边 32的根部到振动 面 31之间留有一个可容密封边 32压缩后的空间。
[0021] 采用这样的结构设计， 当佩戴该眼镜吋， 密封边 32收到头部挤压而收缩， 其端 部与头部皮肤紧密接触， 形成一个将振动面 31包裹其中的密闭空间， 阻止了振 动面产生的机械振动在周围空气中传播。
[0022] 为进一步地的降低漏音， 本实施例中的骨传导耳机在振动面 31的表面还包裹一 层硅胶隔离层 33， 进一步阻断机械振动由振动面 31向周围的传播， 从而降低漏 音。
[0023] 为增强佩戴者的舒适性， 密封边 32的端部设有向外的弧形折边 321， 增加了与 使用者头部接触的表面积， 降低长期使用带来的不适感。
[0024] 本实施例中的骨传导耳机为无线耳机， 主机 3的内部设有无线收发装置， 在镜 腿 2表面还可以设置用于对讲的麦克孔 21。 具体地， 麦克孔 21与主机 3电性连接 ， 麦克孔 21既可以通过无线收发装置对讲， 也可以采集外部环境声音发送给主 机 3， 耳膜受损等听力障碍人士可以通过佩戴本该眼镜， 将他人说话的声音和外 部环境声音通过骨传导耳机传递到头骨处， 并通过头骨传递至听觉器官， 从而 获得听力上的协助。 当然， 本申请其他实施例总， 麦克孔 21还可以设置在眼镜 的镜框上。
[0025] 本申请所给出的基于骨传导的耳机及眼镜， 在耳机主机的振动面设置有密封边 ， 当使用者佩戴该耳机吋， 密封边被压缩并与振动面周围的皮肤紧密贴合， 隔 绝了振动面与周围空气的接触， 阻止了机械振动传递到周围空气中； 在震动面 表面覆盖有硅胶隔离层， 进一步阻断了振动面的机械振动向周围传播， 从而有 效防止了骨传导耳机的漏音。
[0026] 以上内容是结合具体的实施方式对本申请所作的进一步详细说明， 不能认定本 申请的具体实施只局限于这些说明。 对于本申请所属技术领域的普通技术人员 来说， 在不脱离本申请发明构思的前提下， 还可以做出若干简单推演或替换。
