The driving circuit board 10 may be in a layered combination as shown in fig. 1 and 5, but may also be in a single layer form. Although not shown, the driving circuit board 10 may be electrically connected to the piezoceramic sheet 20 in a manner known in the art.
A plurality of conductive contacts 60 are connected to electrical connection points (not shown, but readily understood and implemented by those skilled in the art) on the underside of the driver circuit board 10i. A corresponding plurality of holes (not shown) are provided in the cartridge 30 of the piezoelectric jacquard 100 so that the plurality of conductive contacts pass through. The plurality of conductive contacts and the corresponding plurality of holes should be insulated.
