摘要： A piezoelectric device (50, 60, 70) comprises at least one element (58) that comprises at least one sheet (54) of piezoelectric material defining an area. The element (58) has been mounted or placed on a circuit board (30, 78) comprising at least one conductive layer (51; 701, 702, 703, 704) with at least one opening (35, 37; 81, 82) in the conductive layer (51; 701, 702, 703, 704). The element (58) is located on the opening (35, 37; 81, 82) and supported by edges of said at least one opening (35, 37; 81, 82), in such a manner that the opening (35, 37; 81, 82) extends beyond the area. In addition, the element (58) is sandwiched between an overlay (503) and the circuit board (30, 78) in such a manner that vibrations of the sheet (54) of piezoelectric material are sufficient to cause tactile vibration of the overlay (503).
The patent application contains a parallel independent claim for a piezoelectric device.
