It is worth noting that if the sound comb of an music box is broken and repaired, its value will be greatly reduced. This is the key to identify antique music boxes.

Sound comb, in fact, is to cut the perforated refined steel sheet into the shape of a comb with a milling cutter. In order to achieve the best sound effect and last longer, the sound comb has a quenching process. First, the sound comb is fired at a high temperature above 800℃, then it is soaked in low-temperature oil at 300℃, and then it is gradually heated to 800℃ to fully quench the steel. Then, each sound comb can be accurately produced by grinding with a grinding wheel, and the sound comb in the bass part will be weighted to ensure the best sound quality. Finally, damping sheet made of aramid fiber is pasted on the back of the sound comb.
