An impact sound sensor device has an oscillating weight (2), a piezo element (4), a connection element (6) designed as a base, a printed circuit board (8) and a holder (10). The printed circuit board, the connection element, the piezo element and the oscillating weight are all layered on top of each other like a sandwich. The connection element, the piezo element and the oscillating weight each have a round disk-shaped contour.
