Now there are a lot of people on the active buzzer and passive buzzer concept is not very clear, here to do a brief introduction, I hope to help you use in the future.
Note that "source" here does not mean power supply. Rather, it refers to the source of the oscillation.
The characteristics of a passive buzzer are:
1 Passive does not have an internal oscillator source, so if you use a DC signal can not make it sound. Must use 2K ~ 5K square wave to drive it
2 sound frequency can be controlled, you can make the effect of the "Doraimi hair Solace".
3 In some special cases, and LED can be multiplexed with a control port
Active buzzer is characterized by:
1 active buzzer with internal oscillation source, so as long as the power will be called!
2 Program control is easy, a microcontroller a high and low level can make it sound, while the passive buzzer can not do.
The weight of each set is about 6g

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
