Description

一种骨传导耳机 技术领域
本发明涉及耳机领域，特别是指一种骨传导耳机。
背景技术
骨传导是一种声音传导方式，即将声音转化为不同频率的机械振动，通过人的颅骨、骨迷路、内耳淋巴液传递、螺旋器、听神经、听觉中枢来传递声波。相对于通过振膜产生声波的经典声音传导方式，骨传导省去了许多声波传递的步骤，能在嘈杂的环境中实现清晰的声音还原，而且声波也不会因为在空气中扩散而影响到他人。
现有的骨传导耳机，主要是通过颅骨传递声波，因而需要一个外挂设备（即耳挂部分）将骨传导耳机固定在耳朵的周围，并保证足够的压紧力以保证骨传导耳机能够贴近头部的骨头。不仅增加了成本，并且使用上具有诸多局限性，长时间佩戴容易导致头部不舒服。
发明内容
本发明的目的在于提供一种骨传导耳机，解决现有技术的不足，实现降低成本、佩戴方便。
为了达成上述目的，本发明的解决方案是：
一种骨传导耳机，包括耳机外壳、PCBA、电池、天线、骨传导MIC和受话器；所述耳机外壳的内部形成有容置腔，PCBA、电池、天线、骨传导MIC和受话器均安装在容置腔中；所述耳机外壳凸出形成有用以插入外耳道以实现佩戴的突出部，受话器配合在位于突出部位置的容置腔中，容置腔对应突出部的顶端位置设置有送声孔；所述天线位于容置腔中远离突出部的端部；所述骨传导MIC贴附于容置腔的内壁并位于耳机外壳对应外耳道开口处软骨的位置；所述电池、天线、骨传导MIC和受话器均电性连接于PCBA。
所述骨传导MIC位于耳机外壳对应外耳道的开口处耳屏和/或对耳屏的位置。
一种骨传导耳机还包括MIC固定架；所述MIC固定架安装在容置腔中，并压制骨传导MIC贴附在容置腔的内壁。
所述突出部的外周套设有软胶耳塞。
所述骨传导MIC位于耳机外壳对应耳甲腔侧壁的位置。
所述的一种骨传导耳机还包括磁吸铁片，磁吸铁片安装在容置腔中。
采用上述结构后，本发明通过在骨传导耳机的耳机外壳设置突出部，并将骨传导MIC设置在对应外耳道的软骨位置，通过外耳道的软骨实现骨传导，从而实现骨传导耳机的入耳式佩戴方式，无需耳挂设备便可实现佩戴，不仅佩戴舒服方便，而且可以降低生产成本。

具体实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
本发明为一种骨传导耳机，主要是一种耳塞式的耳机，参考图1至图3所示，为本发明的第一实施例，包括耳机外壳1、PCBA2、电池3、天线4、骨传导MIC5和受话器6。上述耳机外壳1的内部形成有容置腔11，PCBA2、电池3、天线4、骨传导MIC5和受话器6均安装在容置腔11中。
上述耳机外壳1凸出形成有用以插入外耳道7以实现佩戴的突出部12，受话器6配合在位于突出部12位置的容置腔11中，容置腔11对应突出部12的顶端位置设置有送声孔13。上述天线4位于容置腔11中远离突出部12的端部，即耳机佩戴时天线4位于耳朵的外侧。上述骨传导MIC5贴附于容置腔11的内壁并位于耳机外壳1对应外耳道7开口处软骨71的位置。上述电池3、天线4、骨传导MIC5和受话器6均电性连接于PCBA2。
上述骨传导MIC5位于耳机外壳1对应外耳道7的开口处耳屏711和/或对耳屏712的位置，以保证骨传导MIC5间隔耳机外壳1紧贴在头部骨头，提高骨传导MIC5的工作质量和稳定性。
本发明还包括MIC固定架8；MIC固定架8安装在容置腔11中，并压制骨传导MIC5贴附在容置腔11的内壁。
上述突出部12的外周套设有软胶耳塞9，以增加突出部12配合在外耳道7中的紧固程度，并且软胶耳塞9紧配在耳道中可以降低外部噪音的干扰，提高音质。
本发明还包括磁吸铁片10，磁吸铁片10安装在容置腔11中，以提高耳机放置在耳机收纳装备中时的稳固性；上述磁吸铁片10和骨传导MIC5分别位于容置腔11的相对内壁。
参考图2和图3所示，本发明的第一实施例在佩戴时，将突出部12插设在外耳道7中，实现耳机外壳1塞入耳甲腔20，此时耳屏711和对耳屏712夹持耳机外壳1以完成固定，骨传导MIC5间隔耳机外壳1紧贴在外耳道7开口处软骨71的位置，耳机外壳1和软骨71作为介质实现骨传导。
参考图4所示，为本发明的第二实施例，其与第一实施例的不同之处在于：上述骨传导MIC5位于耳机外壳1对应耳甲腔20侧壁的位置。
通过上述结构，本发明通过在骨传导耳机的耳机外壳1设置突出部12，并将骨传导MIC5设置在对应外耳道7的软骨71位置，通过外耳道7的软骨71实现骨传导，从而实现骨传导耳机的入耳式佩戴方式，无需耳挂设备便可实现佩戴，不仅佩戴舒服方便，而且可以降低生产成本。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
