Hand-Cranked Music Box Kit – DIY Mechanical Instrument Craft (Model R-65)

Description

Description:

The eight-tone piano is composed of a set of flat metal strips of different lengths fixed to the frame. The metal strips are arranged in chromatic order according to the piano keys. The player uses a stick to strike the middle of the piece to produce a soft and clear sound.

The shorter the piano piece, the higher the tone, the longer the piano piece, and the lower the tone. Because the speed of object vibration is related to the level of sound, the faster the object vibrates, the higher the sound is emitted, and the slower the object vibrates, the lower the sound is emitted. When the thickness and width of the piano piece are the same, the length of the piano piece determines the tone of the sound.

Required production tools and self-contained materials:

You need to prepare a small screwdriver. Screwdriver installation screws are required during the production process.
