Abstract
A miniature piezoelectric element is conductively mounted on a metal diaphragm having one or two projecting tabs which provide two solderless terminals. An insulating area is screened onto the diaphragm around the piezoelectric element and out onto one tab. A conductive layer is formed on the upper surface of the active element and out onto the insulating area on the tab without contacting the diaphragm. The diaphragm can then be supported within any suitable housing with the tab or tabs projecting for contact by a miniature connector.
