Snap Circuits Parts Spotlight: Melody IC (U32)
The Melody IC (U32) contains a specialized sound-generation integrated circuit (IC), a small speaker, and a few supporting components. The IC has a recording of the melody, which it makes into an electrical signal for the speaker. The speaker converts the signal into mechanical vibrations. The vibrations create variations in air pressure, which travel across the room. You “hear” sound when your ears feel these air pressure variations.
