¾认本 陶瓷介质， 缩小了体积， 增加了电容量。
附图说明
下面结合附图和具体实施方式对本发明作进一步说明。 本发明的保护 范围将不仅局限于下列内容的表述。
图 1为本发明的原理框图；
图 2为本发明的整体结构示意图；
图 3为本发明的电路原理图。
具体实施方式
如图 1〜3所示，振动式陶瓷发电机，靠压缩空气驱动，它含有激励电源 及数个并联的发电单元；所述发电单元含有腔体单元 N;在腔体单元 N内中 间位置设有正极性固定板 M以使其形成两个独立腔室； 在所述独立腔室内 分别配有导电膜片以使腔体单元 N最终形成四个独立腔室单元 Al、 A2、 B、 C; 所述独立腔室单元 B、 C分别设有气流配送通道 0、 P; 所述正极性固定 板 M上配有通孔 D;所述激励电源与正极性固定板 M及导电膜片相配接。本 发明所述发电单元间配有绝缘材料层 E。本发明所述正极性固定板 M采用导 电薄板； 在所述导电薄板的双面覆有高介电陶瓷介质层。
本发明振动式陶瓷发电机可设计在一个筒形箱体内， 均匀分设数个发 电单元， 每个发电单元就是一台振动变电容式陶瓷发电机， 多个发电单元 并联使用， 组成一个大的完整的发电机。
箱体及各发电单元采用绝缘材料制成，各发电单元独立密闭，不透气， 并能承受额定气体压力。 在发电单元中间位置设置正极性固定板， 正极性 固定板基板采用导电薄板制成， 双面披覆高介电陶瓷介质层， 在板面上钻 若干个通气孔 D。正极性固定板将发电单元分成两半，采用两片弹性导电膜 片，把已分成两半的组合发电单元再分成四个四分之一的独立腔室单元 Al、 A2、 B、 C， 分别称 M、 A2、 B、 C室， 其中 B、 C小室各自独立密闭， 在箱 体上的对应位置各自开一个通气管道孔， 便于充放气， Al、 A2室虽然已被 正极性固定板隔开， 但由于该板上有若干通气孔， 可以使两侧空气自由流 通， Al、 A2室也要组合成一个自闭空间与外界隔绝， 并要保证室内能维持 一个稳定的额定气压值， 以协调两侧弹性膜片同步动作。
当 C室的通气孔被控制阀控制在开启状态时， B室充气并达到额定气压 值， 使振动膜片（也称负极性片）贴向右侧， 凡奇数膜片（X)组均靠近正 极性固定板， 两者形成一个完整的电容器， 激励电源将对该电容充电， 充 电电量 Q=CU。凡偶数膜片（Y)组均靠近侧壁， 此态呈放电状态， 然后控制 阀将 B室通气孔打开放气， C室充气，迫使弹性膜片靠向左侧， 这时凡（X) 组膜片均处于放电状态， （Y) 组膜片均处于充电状态。
从激励电源来看， X、 Y组膜片均处于等电位， 但从动作时看， X、 Y组 因一组处于充电状态， 另一组处于放电状态。 根据公式^01， 当充电电量 Q值存在时， 当 C— 0， 则 ϋ→∞， 两者产生了一个电位差，在外电路即可形 成电流。
