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.
In the mid-20th century, the rise of semiconductor technology completely changed the form of
music movements. Electronic
music movements gradually replaced traditional mechanical structures and became the mainstream in greeting card applications. The core breakthrough during this period was the storage of melody signals in application-specific integrated circuits (ICs). The signals were amplified by transistors to drive miniature speakers to produce sound, and the volume was greatly reduced to a few cubic centimeters, which could be easily embedded in
greeting cards.
Greeting card music movements at this stage had distinct application characteristics: although the music content could not be changed, manufacturers provided a wealth of fixed music options, covering various scenarios such as holiday blessings, birthday wishes, and friendship messages; the playing time achieved hierarchical selection, expanding from the initial 5-second short melody to 10-30 second complete chorus segments, meeting the content needs of different
greeting cards; the playing method also upgraded from a single manual trigger to simple electronic control, with button playback becoming the mainstream form - when the user presses the raised button on the
greeting card, the circuit is connected to start playback, which is easy to operate and has significantly improved stability. Some high-end products also tried the magnetic control trigger method, which controls the on-off of the circuit through the displacement of the magnet when the
greeting card is opened and closed, realizing the linkage effect of "playing as soon as the cover is opened".
III. Function Expansion Stage: Diverse Triggers and Experience Upgrading (Early 21st Century - 2010s)
Entering the 21st century, the integration of sensor technology and microelectronic technology has made the functions of
greeting card music movements more diverse, achieving dual upgrades in playback methods and user experience. The application of light-controlled playback technology became an important highlight of this stage. The
