In the past, it was probably impossible for ordinary people to make a music box, because it was a kind of machinery that required very accurate geometric dimensions of the sound-producing materials, otherwise it would be impossible to produce beautiful melody. Also There must be an energy storage part to store the energy and then slowly release it to drive the machine to strike the pronunciation material. According to the pre-set music (that is, the pronunciation materials of different sizes are pronounced in a certain order), the energy storage device The most commonly used ones are similar to clockwork springs. When the spring is tightened, energy is stored, and when it is released, it can drive the machine to make sound.

Modern music boxes are all electronic, and compared with old-fashioned ones, The sound quality of the music box is much more beautiful. In addition to playing chords, it can also be sung by real people, and its capacity is much larger. Its structure is: an integrated block whose function is to store music files and amplify the circuit, and can be connected to a small speaker and power supply. It is connected to a complete music box circuit. Generally, multiple songs are stored in the integrated block. If you buy a set of components, you can connect them as shown in the picture and it will work normally without testing. There are only two sets of specific wiring points, and each set has only two connectors. For the power supply (battery) group, please note that the positive and negative poles of the power supply cannot be connected reversely. For the small speaker group, you can connect the positive and negative poles at will.

In short, it is very easy to make an electronic music box. And it can achieve very ideal results.
