Producing sound through electronics.
I want make something that produces a 'meow' sound. Like, for example a beeper produces a 'beep' sound for an alarm, but I wanted to make something that produces a 'meow' sound. I have broken many cars and have found that a magnet produces the sound. How is the magnet actually programmed to produce the sound. What is the circuitry involved? Can I make something like that?
