将金属弹片2放入制造底座本体1的模具中，使金属弹片2镶嵌于成型后底座本体1底部；
采用二次注塑工艺或双色模注塑工艺将软胶体3附设在位于底座本体1底部的金属弹片2上，使软胶体3包裹金属弹片2，并填充镂空区域21。
上述方法制造得到的底座为一个整体，不可拆分，其中，底座本体1为塑胶圈，金属弹片2为平面结构，呈圆形，当然金属弹片2也可以为其它形状，利用二次注塑工艺或双色模注塑工艺将金属弹片2与软胶体3的组合，代替传统的硬质塑胶，由于金属弹片2及软胶体3具有很好的弹性，所述底座用于共振音响发生器时，所述底座振动时的顺性更好，有利于导振体上下运动，从而使该共振音响发生器振动灵敏度高、振动幅度大，电声的转化率更高，解决了现有的共振音响存在发音小、中低频表现不好及电声转换效率低的问题；此外，镶嵌于底座本体1底部的金属弹片2和粘接于金属弹片2上及底座本体1底部的内壁的软胶体3，不用人工的组装，使产品的精密度更高，并且通过调整金属弹片2中镂空区域21的面积比例，也就是说调整金属弹片2与软胶体3的面积比例，从而调节产品的振动幅度，有利于满足市场的多样化需求，所述底座突破了现有共振音响发生器的底座技术，能在同等条件下，得到更为完美的听觉效果、低频更丰富、声音更大。
如图1至图5所示，本发明还提出一种共振音响发生器，包括中空结构的底座本体1，底座本体1内腔底部嵌有金属弹片2，金属弹片2具有镂空区域21，底座本体1内设置有包裹金属弹片2、填充镂空区域21的软胶体3。
其中，底座本体1为塑胶圈，金属弹片2为平面结构，呈圆形，当然金属弹片2也可以为其它形状，利用金属弹片2与软胶体3的组合，代替传统的硬质塑胶，由于金属弹片2及软胶体3具有很好的弹性，所述底座振动时的顺性更好，有利于导振体上下运动，从而使该共振音响发生器振动灵敏度高、振动幅度大，电声的转化率更高，解决了现有的共振音响存在发音小、中低频表现不好及电声转换效率低的问题；此外，镶嵌于底座本体1底部的金属弹片2和粘接于金属弹片2上及底座本体1底部的内壁的软胶体3，不用人工的组装，使产品的精密度更高，并且通过调整金属弹片2中镂空区域21的面积比例，也就是说调整金属弹片2与软胶体3的面积比例，从而调节产品的振动幅度，有利于满足市场的多样化需求，底座突破了现有共振音响发生器的底座技术，能在同等条件下，得到更为完美的听觉效果、低频更丰富、声音更大。
如图4至图7所示，进一步地，软胶体3的上下端面分别向外延伸有上凸台4a、下凸台4b，上凸台4a、下凸台4b位于底座本体1的中心，底座本体1内腔底部还设置有贯穿上凸台4a、下凸台4b的通孔5，下凸台4b上设置有第一导振体101,上凸台4a上设置有第二导振体102，第一导振体101与第二导振体102通过螺钉103穿过通孔5连接。上凸台4a及下凸台4b与软胶体3为同样的材质，通孔5竖直贯穿上凸台4a及下凸台4b，上凸台4a及下凸台4b呈圆形，第一导振体101设于凸台4a上、第二导振体102设于凸台4b上，第一导振体101、第二导振体102相对于底座本体1上下运动。
如图1、图2、图4和图5所示，进一步地，底座本体1内腔底部还设置有伸入镂空区域21的数个水平臂6，每水平臂6与金属弹片2平行设置，每水平臂6的底侧设置有卡柱61，每卡柱61环绕于凸台4a分布。本实施例中水平臂6为四个，四个水平臂6均匀分布在底座本体1内腔底部壁体上，填充镂空区域21中软胶体3粘接于水平臂6，四个卡柱61及下凸台4b与第一导振体101接触，可使第一导振体101、第二导振体102在上下振动时，保持在竖直方向且上下振动平稳。底座本体1、水平臂6及卡柱61为塑胶材质，卡柱61上还设置有包裹其的软胶，以配合第一导振体101、第二导振体102上下振动。
如图6和图7，具体地，还包括一外壳105，外壳105与底座本体1连接，外壳105内设置有音圈骨架106、环绕线圈107、磁体108及导磁体109，音圈骨架106与第二导振体102连接，环绕线圈107设于音圈骨架106上，磁体108安装于外壳105内，导磁体109与磁体108连接。具体地，外壳105与底座本体1套接，外壳105具有外螺纹104，底座本体1内腔的壁体设置有内螺纹11，外壳105与底座本体1通过外螺纹104、内螺纹11配合连接，方便以后拆装，导磁体109套设于磁体108上，外壳105为金属外壳，可屏蔽外界电磁场的干扰，加强了音响的效果；磁体108套设有导磁体109，以便产生更强的磁场。外壳105、环绕线圈107、磁体108及导磁体109都呈圆形，外壳105与环绕线圈107、磁体108及导磁体109在同一轴线上。
如图6所示，优选地，第一导振体101底侧设置有胶垫100。胶垫100可有效防止振动产生的杂音，使音响的音效更好。
综上所述，所述共振音响发生器通过与外部音源设备连接使用，使用时，将所述共振音响发生器放置在介质平面上，最好是硬度较高的物体表面，使第一导振体101上的胶垫100
与物体表面贴合，当环绕线圈107 内有随音乐信号变化的交流电流通过时，环绕线圈107
上就会产生一个极强的变化的磁场，该磁场和磁体108及导磁体109本身产生的磁场共同作用，使得第一导振体101及第二导振体102随着音乐信号的变化而产生不同程度的振动，第一导振体101及第二导振体102再将产生的动能传递到放置的介质上（物体表面），从而推动介质振动发声；所述共振音响发生器，由于底座本体1底部设置有金属弹片2及软胶体3，第一导振体101、第二导振体102产生的动能传递到金属弹片2及软胶体3
时，金属弹片2及软胶体3
产生弹性形变，且随着动能大小的变化，金属弹片2及软胶体3的形变量也随之变化，产生共振，振动的幅度更大，振动的阻力也相对减小，电磁转化率高，其外接音源播放出来的音乐具有更好的听觉效果，悦耳动听，此外，中低频更加丰富，声音也更大，满足更多消费者的需要。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
