Abstract: A piezoelectric device comprises at least one element comprising at least one sheet of piezoelectric material. The element is mounted on a circuit board comprising at least one conductive layer having at least one opening. The element is located on the opening and supported by edges of the opening in such a manner that the opening extends laterally beyond the area of the sheet of piezoelectric material. The element is sandwiched between an overlay and the circuit board in such a manner that vibrations of the sheet of piezoelectric material are sufficient to cause vibration of the overlay.
