This article reviews the development history of music movements. They started from the mechanical prototype of music boxes at the end of the 18th century, were miniaturized and applied to greeting cards through the promotion of electronic technology, and then expanded their functions by integrating sensor technology. Now, they are developing in the direction of intelligence. The music mechanism for greeting cards has fixed music but optional tracks. It supports duration grading and multiple triggers, adding a sense of ceremony to emotional transmission.
As a miniature sound-generating device capable of accurately reproducing melodies, the development of
music movements has been accompanied by the iteration of precision manufacturing technology and the upgrading of emotional expression needs. Particularly in the field of
greeting cards, its application has turned such "talking blessings" into a unique carrier for conveying emotions, which not only retains the warmth of traditional
greeting cards but also adds a pleasant surprise in the auditory dimension. From mechanical structures to electronic control, the development history of
music movements clearly reflects the progressive trajectory of miniature sound-generating technology.
I. Origin and Embryonic Stage: Preliminary Exploration of Mechanical Structures (Late 18th Century - Early 20th Century)
The technical origin of
music movements can be traced back to music boxes in the late 18th century. At that time, music boxes used brass combs as sound-generating components, and the convex points on the cylinder drove the combs to vibrate and produce sound. This purely mechanical structure became the primitive form of
music movements. However, the device was relatively large at that time, mostly used as an ornament, and could not be applied to thin and light carriers like
greeting cards.
In the early 20th century, the development of precision machining technology promoted the miniaturization of
music movements. Manufacturers reduced the volume of the movement to the size of a palm by reducing the gear modulus and optimizing the arrangement of combs. Although it was still driven by machinery, it had initially achieved portability. The melodies of the movements at this stage were fixed, mostly classic folk songs or Christmas carols, with a short playing time (usually 3-5 seconds), and required manual winding to trigger, laying a structural foundation for its subsequent application in greeting cards.
