<p>The musical box mechanism has a bellows (8) coupled to an air outlet unit which is movable relative to a perforated foil (1) so that the air outlets (10) cooperate with the perforations to produce the notes. The perforated foil (1) is in the form of a sleeve enclosing the bellows (8) with the air outlet unit (6) moving axially relative to this envelope. The bellows (8) may be extended via a handle or pull cord (7) attached to the air outlet unit (6) or the mechanism may be turned upside down, so that the air outlet unit (6) falls under its own weight, thus extending the bellows (8).</p> |
