Abstract (en)
[origin: EP2339412A2] The mechanism (1) has a gong (21) connected to a gong-carrier (22), and a hammer (2) mounted on a plate for striking the gong at predetermined times. A damping counterspring (5) i.e. lever, maintains the hammer at a distance from the gong in an idle mode. A spring (3) is in the form of a beam or a strip spring and is wound to drive the hammer against the gong in strike mode to produce an acoustic sound. A stop member (10) is provided on path of the spring in the direction of the gong for increasing the strike speed following contact of a part of the spring in action against the stop member.
