Hign-concerned Chemical : None
Model Number : 1097
Origin : China
The characteristics of the passive buzzer is:
1 passive internal without shock source,so if use dc signal can't make it.Must use 2 k ～5 k square wave to drive it
For more than 2 sound frequency control,can make "m hair sola west"effect. 2 in some particular case,can reuse and LED a control
The characteristics of the active buzzer is:
1 Active buzzer inside with shock source,so as long as the electricity will call
2 Program control convenient,single chip microcomputer a high and low level can make the sound,and the passive buzzer is can't do.
Each weight is about 6 g

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.
