Description
本发明属于喇叭技术领域，尤其涉及一种金属弹波喇叭。
近年来，随着电声行业的飞速发展，超薄平板喇叭在电声行业的应用越来越广，其结构、工艺、功率和音质要求难度也随之越来越大。在超薄平板喇叭开发设计过程中，为了节省空间，普遍采用无弹波的结构方式来解决喇叭全高问题。
现有技术中喇叭的振动系统由平板鼓纸和音圈组合而成，无弹波结构，依靠鼓纸悬边抑制喇叭振动幅度和中心定位。该喇叭按照传统方式将端子订在盆架的底面，以方便接线。然而该喇叭当中音圈拉出导线的弧度很难控制，很容易产生碰触异常音。还有该喇叭单一地依靠鼓纸悬边抑制喇叭振动幅度和中心定位，加大功率以后喇叭音圈很容易碰撞到U铁底部产生异常音，致使喇叭功率很难上去。
本发明所要解决的技术问题为提供一种金属弹波喇叭，旨在解决现有技术中喇叭音圈拉出导线的弧度难以控制容易碰到盆架和平板鼓纸，音圈容易碰到U铁底部，以及喇叭功率不足的问题。
为解决上述技术问题，本发明是这样实现的，一种金属弹波喇叭，包括：
平板鼓纸、盆架、音圈、吸音棉、铁片、磁铁、U铁及两个金属弹波；

所述音圈的顶面与所述平板鼓纸的底面粘接，并嵌置于U铁的内侧壁与磁铁的外周缘之间，且不与U铁、磁铁、吸音棉及铁片接触；
两个所述金属弹波以所述音圈为中心，对称设置在所述盆架中，其中所述金属弹波的音圈接线部位于靠近所述音圈的一端；
所述金属弹波的第一固定部粘接在所述平板鼓纸的底面，第二固定部与所述盆架粘接；
所述音圈上包括两根音圈引出线，两根所述音圈引出线分别与两个所述金属弹波的音圈接线部连接；
所述对外接线部用于与外部导线连接。
进一步地，所述音圈接线部上开设有第一穿线孔，所述音圈引出线穿过所述第一穿线孔，并与所述音圈接线部焊接。
进一步地，所述对外接线部上开设有第二穿线孔，外部导线穿过所述第二穿线孔，并与所述对外接线部焊接。

音圈3的顶面与平板鼓纸1的底面粘接，并嵌置于U铁7的内侧壁与磁铁6的外周缘之间，且不与U铁7、磁铁6、吸音棉4及铁片5接触。
两个金属弹波8以音圈3为中心，对称设置在盆架2中，其中金属弹波8的音圈接线部84位于靠近音圈3的一端。
金属弹波8的第一固定部81粘接在平板鼓纸1的底面，第二固定部82与盆架2粘接。
音圈3上包括两根音圈引出线9，两根音圈引出线9分别与两个金属弹波8的音圈接线部84连接。
