The "source" here does not refer to the power supply. It's the source of the shock. That is to say, the active buzzer has a source of shock inside it, so it will chirp as soon as it is powered on.

However, there is no source of shock in the passive interior, so it cannot be chirped if the dc signal is used. It must be driven by a square wave of 2K~5K.

Active buzzers are often more expensive than passive ones because they have multiple oscillating circuits.

The advantage of the passive buzzer is: 1. Cheap, 2. The sound frequency can be controlled, and the effect of "doremi fa sohrassiz" can be achieved. 3. In some special cases, an active buzzer with a control port can be reused with LED.
