Background

The music box is also called as a music box, is a motor-driven sound musical instrument and can automatically play music, and the main part of the music box consists of a power source, a sound tube, a sound board, a damping, a bottom plate, a transmission mechanism and the like. The principle is that the power drives the sound tube with small bulges on the surface to rotate at a constant speed, and when the bulges pass through the soundboard soundbar, the reed is stirred to vibrate according to the set vibration frequency to make the reed generate the set sound. The soundboard portion of the music box is made of thin strips which are cut on a piece of elastic steel plate to be consistent in length but different in thickness and thickness (the thickness and thickness are different according to set vibration frequency). A bump on the sound tube is equivalent to a note on the music score. The sound tube rotates according to regularly set convex points, the convex points scratch the edge of the sound plate, and the different sounds are generated due to the different convex points.
