Passive buzzers do not have a built-in oscillator, so they need an AC audio signal to produce sound. They require more complex circuitry to control them, like an oscillating timer or a programmable microcontroller. The advantage of passive buzzers is that they can vary the pitch or tone of the sound. They can be programmed to emit a wide range of frequencies or musical notes
