附图说明
图1为本发明的一种圈铁式同轴入耳式耳机的发音单元的结构示意图。
示意图中的标号说明：
1、动圈；11、动圈振膜；2、动铁；21、动铁音管；22、动铁出音口；3、连接管。
具体实施方式
为进一步了解本发明的内容，结合附图对本发明作详细描述。
如图1所示，本发明的一种圈铁式同轴入耳式耳机的发音单元，包括动圈1和动铁2，与现有的动圈1结构不同，在本发明中，动圈1的中轴线上贯穿有一个通孔，动圈振膜11的中心向内凹陷形成开口，该开口与上述的通孔相连通。对于传统的动圈单元，其动圈振膜11的中心向外隆起，但在实际的动圈发音过程中，动圈振膜11的中心部分基本不起作用，因此，本发明在动圈1的中轴线上开设贯穿整个动圈1的通孔，不会影响动圈1原本的音质效果。动圈振膜11的中心向内凹陷形成开口，且该开口与上述的通孔相连通形成动铁出音口22，动铁2固定于动圈1的后部，且动铁2的动铁音管21与上述的通孔同轴对应，这样，动铁2与动圈1位于同一轴心上，构成圈铁式同轴发音组件。另外，动铁音管21上还连接有一段连接管3，连接管3延伸至动铁出音口22处；动铁音管21与动铁出音口22的距离小于10mm。
下面结合实施例对本发明作进一步的描述。
实施例1
结合图1，本实施例的一种圈铁式同轴入耳式耳机的发音单元，包括动圈1和动铁2，动圈1的中轴线上贯穿有一个通孔，该通孔贯穿动圈1后部的磁铁以及前部的动圈振膜11，动圈振膜11的中心向内凹陷形成开口，该开口与上述的通孔相连通，构成动铁出音口22；动铁2固定于动圈1的后部，且动铁2的动铁音管21与上述的通孔同轴对应，具体在本实施例中，动铁2与动圈1之间的固定方式采用激光焊接，连接可靠，精密度高，使用寿命长，便于将本实施例中的发音单元直接安装于入耳式耳机，方便了耳机的后续装配。本实施例中的动铁2由动圈1轴心上的通孔向外出音，动铁2发出的中、高音与动圈1发出的低音沿同一轴线向外传播，在人耳的完整音频范围内，充分地发挥了动圈1的低音和动铁2的中高音优势，且动圈1和动铁2的发音相互不受阻挡，低、中、高频没有损耗，实现了完美再现原音色的效果，噪音和失真小，同时大大降低了耳机的造价，可以满足大众消费者的使用需求。
本实施例的一种圈铁式同轴入耳式耳机的发音单元，动铁音管21上还连接有一段连接管3，连接管3延伸至动铁出音口22处，动铁2发出的音频直接通过连接管3传输到动铁出音口22，进一步地防止了动铁2的音频损耗和动铁2对动圈1的音频干扰；同时，还避免了加工较长的动铁音管21，降低了细长且微小的动铁音管21的加工难度，节省了产品生产成本。在本实施例中，动铁音管21与连接管3之间的连接方式采用全缝隙激光焊接，结构变形小，连接可靠，密封效果好，精密度高，使用寿命长。此外，动铁音管21与动铁出音口22的距离小于10mm，即如图1中所示的L<10mm，在10mm范围内，动铁2的音频不会因传输距离而出现损耗，使全音域的声音相位保真度得到提高，从而提高了声音的解析力，实现了高保真的音频效果。
实施例2
本实施例的一种圈铁式同轴入耳式耳机的发音单元的基本结构同实施例1，不同之处在于：本实施例中的动铁2与动圈1之间的固定方式采用胶水粘接，胶水固化时间短，连接快速方便，连接可靠，可提高产品的生产效率；动铁音管21与连接管3之间的连接方式采用激光点焊后辅以胶水密封焊缝，连接可靠，密封效果好，相对于实施例1中采用的全缝隙激光焊接而言，动铁音管21与连接管3的连接更加方便快捷。
本发明实施例1和实施例2的一种圈铁式同轴入耳式耳机的发音单元，动圈1的中轴线上贯穿有一个通孔，动圈1的其它结构及发音原理与现有技术相同，与现有的同轴式耳机不同，本发明充分利用动圈1良好的低音效果和动铁2良好的中、高音效果，动圈1和动铁2的发音相互不受阻挡，低、中、高频没有损耗，实现了完美再现原音色的效果，噪音和失真小，同时，结构简单，大大降低了耳机的造价，满足了大众消费者的使用需求。安装时，首先将连接管3与动铁音管21通过全缝隙激光焊接或激光点焊后辅以胶水密封焊缝，确保密封良好；然后将连接管3对准动圈1中轴线上的通孔并插入，利用激光焊接或胶水粘接将动铁2固定于动圈1后部的磁铁上，此时连接管3伸至动圈振膜11中心向内凹陷的开口处，形成动铁出音口22。本发明的一种圈铁式同轴入耳式耳机的发音单元，结构简单，体积小，安装方便快捷，使入耳式耳机可以做得更小，增加了耳机的佩戴舒适度。
以上示意性地对本发明及其实施方式进行了描述，该描述没有限制性，附图中所示的也只是本发明的实施方式之一，实际的结构并不局限于此。所以，如果本领域的普通技术人员受其启示，在不脱离本发明创造宗旨的情况下，不经创造性地设计出与该技术方案相似的结构方式及实施例，均应属于本发明的保护范围。
