    Abstract: The doorbell has the drive motor (6) firmly located in a tubular sleeve (2), secured to one side of a base plate (7). The motor shaft carries a rotor (3) and clapper lines (4), offset through 120 deg., moving into a horizontal position by centrifugal force, on the rotor rotation. The clapper motion generates the sound, as the clapper ends strike against sound tubes (5) suspended from the base plate via electrically conductive suspension (11). Simultaneously they provide electrically conductive connection for successive activation of optical display elements (8).
