具体实施方式
下面结合图1至图6，对本发明做进一步说明：
如图1和图2所示，本发明网状电子鼓包括鼓盘盘体10、鼓圈1、网面2、数据采集模块和数据处理模块。
数据采集模块包括触发器和传导介质，传导介质为磁性部件31，磁性部件31设置在一种软性材料层3中，触发器包括与磁性部件31非接触匹配的霍尔传感器51。
网面2由三层网面层叠加而成，其靠近包含磁性部件31的软性材料层3的侧网面为白色，鼓圈1将网面2固定安装在鼓盘盘体10上。霍尔传感器51安装在一PCB板5板的下表面上，PCB板5的上表面附着有弹性恢复材料层4，PCB板5放置在第一软性发泡缓冲材料层6的安装孔中，第一软性发泡缓冲材料层6下方设有第二软性发泡缓冲材料层9，第二软性发泡缓冲材料层9附在固定板7上，并且固定板7通过螺丝71固定在鼓盘盘体10上。
装有磁性部件31的软性材料层3附着于弹性恢复材料层4上表面，霍尔传感器51位于磁性部件31的正下方，装有磁性部件31的软 性材料层3与装有霍尔传感器51的PCB板5同心且靠弹性恢复材料层4将装有霍尔传感器的PCB板5与装有磁性部件31的软性材料层3完全分隔开来的。
1、软性材料层3：其可以为硅橡胶，例如：其邵氏硬度为30°，其固定磁性部件31用，鼓棒敲击后弹力好。
2、弹性恢复材料层4：其可以为海棉，密度为22kg/m 3，材质柔软更软，受外力压缩后回弹性好、回弹快。
其作用一：因鼓盘盘体触发信号原理就是磁性部件31与下方的霍尔芯片51通过不断的距离改变使得磁通量发生变化产生正弦波电压信号，因此选用海棉来实现这个功能。作用二：弹性恢复材料层4在向下震动后由于弹力快速回复并再次与网面2接触，在未继续受力的情况下不会产生第二次震动，不会继续产生信号。
3、第一软性发泡缓冲材料层6：其材质为氯丁橡胶发泡材料(俗称：克回力，又称CR泡棉)，例如：硬度可以为15°。
其第一作用：固定有霍尔芯片的PCB 5；第二作用：当鼓棒敲击网面2时的力度传至软性材料层3，再使弹性恢复材料层4来回震动改变距离，第一软性发泡缓冲材料层6使敲击的力度进一步减弱，当传至第一软性发泡缓冲材料层6时力度更进一步减弱或吸收了；第三作用：当敲击鼓圈1或鼓盘盘体10，敲击产生的振动能量除了被传感器8感应，还会向上方的软性材料层3以及磁性部件31传导，第一软性发泡缓冲材料层6可以吸收振动能量避免磁性部件31受到影响。
4、第二软性发泡缓冲材料层9：其材质为氯丁橡胶发泡材料(俗称：克回力，又称CR泡棉)，其硬度同第一软性发泡缓冲材料层6。其起到进一步减弱上述步骤传过来的力度为0，使其不传至鼓盘盘体10上，因鼓圈1或鼓盘盘体10的触发是靠固定在鼓盘盘体10上的传感器8来感应产生信号，如敲网面2有信号传至鼓盘盘体10，则会出现串扰边的信号。同理，也可以衰减和吸收鼓圈1或鼓盘盘体10敲击后向上对软性材料层3以及磁性部件31的影响。
总之，敲鼓圈1或鼓盘盘体10时，鼓圈1或鼓盘盘体10的震动信号通过第二软性发泡缓冲材料层9传至第一软性发泡缓冲材料层6，再传至弹性恢复材料层4，最后传至软性材料层3，因均使用发泡缓冲材料，敲鼓圈1或鼓盘盘体10的力度一步一步衰减，使弹性恢复材料层4基本上无震动，不会产生距离化，即不会产生磁通量变化，不会有电压信号产生，避免了敲击边串扰面的情况。
硬度比较：第一软性发泡缓冲材料层6和第二软性发泡缓冲材料层9硬度都大于弹性恢复材料层4。
当敲击网面2时，装在软性材料层3中的磁性部件31产生向下震动，磁性部件31与霍尔传感器51的距离发生改变，霍尔传感器51感应到的磁场范围产生变化，由此生成音频电压信号输出给数据处理模块，数据处理模块将接收到的音频电压信号进行处理，得到所需的音频信号并输出。
敲击网面2后，网面2下的弹性恢复材料层4在向下震动后由于弹力快速回复并再次与网面2接触，在未继续受力的情况下不会产生第二次震动，也就不会继续产生信号。因此软性材料层3顶住网面2，也避免了敲击网面时产生机械噪音。
由于霍尔传感器51与磁性部件31都是间接固定在鼓盘盘体10上，通过冶具可以完全保证霍尔传感器51与磁性部件31同心，这样大大提高了网面信号，避免了中国专利(申请公布号：CN106531139A)公布的网状电子鼓因霍尔传感器与磁性材料分别在不同部件造成相互偏位，造成即使网面震动也只能产生较小的信号，每个鼓盘盘体10信号有差异，鼓盘盘体10灵敏度低。
如图3所示，PCB板5通过支撑部件52固定在安装孔中，支撑部件52的上部开有T型槽521；PCB板5位于T型槽的水平部分，霍尔传感器51位于T型槽的垂直部分。弹性恢复材料层4上表面为凹槽41结构，软性材料层3底部嵌入凹槽41中。凹槽41可以锥形凹槽或矩形凹槽或不规则形状凹槽，软性材料层3底部也对应设置为锥形 结构、矩形结构或不规则结构与不同形状的凹槽41进行配合。
软性材料层3的上部与网面2固定连接。霍尔传感器51与磁性部件31为同轴或同心设置。固定板7与鼓盘盘体10通过一个或多个螺丝71进行固定。
如图4所示，软性材料层3中埋设磁性部件31。
如图5所示，PCB板5下方固定有霍尔传感器51。
如图6所示，当数据处理模块包括整形电路、数模转换电路、控制电路、DSP数据处理电路、音源存储电路、模数转换电路和后级信号放大电路；霍尔传感器和整形电路的输入端连接，整形电路的输出端和数模转换电路的输入端连接，数模转换电路的输出端和控制电路的输入端连接，控制电路的输出端和DSP数据处理电路的输入端连接，DSP数据处理电路的输出端和音源存储电路的输入端连接，音源存储电路的输出端和模数转换电路的输入端连接，模数转换电路的输出端和后级信号放大电路的输入端连接，后级信号放大电路的输出端输出音频信号时，可以将霍尔传感器随磁性范围变化提供的音频电压信号处理后得到所需的音频信号输出；
如图7所示，当数据处理模块还包括前级信号放大电路，霍尔传感器通过前级信号放大电路和整形电路的输入端连接，前级信号放大电路和的输入端和霍尔传感器连接，前级信号放大电路的输出端和整形电路的输入端连接时，可以放大因霍尔传感器随磁性范围变化较小提供的较小的音频电压信号，使其满足音频输入信号的要求；
前级信号放大电路包括第一电阻R1、第二电阻R2、第三电阻R3、第四电阻R4、第五电阻R5、第一电容C1、第二电容C2、第三电容C3和三极管Q1；第一电容C1的一端为前级信号放大电路的输入端与霍尔传感器H连接，霍尔传感器H还与电源输出端连接，第一电容C1的另一端和第一电阻R1的一端连接，第一电阻R1的另一端、第二电阻R2的一端、第三电阻R3的一端和三极管Q1的基极连接，第二电阻R2的另一端、第四电阻R4的一端和第二电容C2的一端均接入电 源，第二电容C2的另一端接地，第三电阻R3的另一端接地，第四电阻R4的另一端、三极管Q1的集电极和第三电容C3的一端连接，三极管Q1的发射极和第五电阻R5的一端连接，第五电阻R5的另一端接地，第三电容C3的另一端为前级信号放大电路的输出端时，该电路将霍尔传感器随磁性范围变化提供的音频电压信号进行放大使其满足音频输入信号的要求。
上面结合附图对本发明进行了示例性的描述，显然本发明的实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种改进，或未经改进将本发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围内。
