Abstract (en)
[origin: EP2346026A2] The device (11) has a signal generator (13) e.g. piezo-buzzer, comprising a piezo-ceramic disk (14) and arranged on a printed circuit board (18). The board has an opening (21) in an area of the piezo-ceramic disk and/or metal membrane (15). The metal membrane overlaps the opening for attachment on the printed circuit board in an edge area of the opening. The piezo-ceramic disk is arranged on the metal membrane in the edge area of the opening. A contact protrusion unit (29) is provided for electrical contacting of the signal generator at the edge area of the opening.
