Musical module for use in clock movement of wristwatch for producing music, has keyboard comprising blades vibrated by activation elements, where activation elements have different heights for modifying sound intensities of blades

摘要

The module has a keyboard (1) comprising a set of rectilinear blades (3) vibrated by corresponding activation elements i.e. pins (11), carried by a movable substrate that is in the form of a toothed disk (10) or a barrel. The activation elements of the movable substrate have different heights for modifying sound intensities of the vibrated blades. The pins are arranged in a specific manner based on music to be produced by rotation of the disk or the barrel. The blades are arranged parallel to each other.
