Patch buzzer, also known as patch buzzer, SMD buzzer. What is patch type? It means that the appearance and size of the plastic case of the buzzer is small, it is a roll type packaging, and the pins can be flat affixed to the PCB, and the patch type package is another kind of packaging form of the buzzer relative to the plug-in type.
The advantages of the chip buzzer products are: small size, light weight, clear and thorough sound quality, solid structure, stable quality, high temperature resistance (can pass the wave welding), saving manual welding labor hours; Among them, the electromagnetic patch buzzer consumption current is generally relatively large, if you want to choose the power consumption current is relatively small, you should choose the piezoelectric patch buzzer.
According to the different structure and principle, it is divided into: passive electromagnetic patch buzzer, active electromagnetic patch buzzer; Passive piezoelectric patch buzzer, active piezoelectric patch buzzer.
Chip buzzer, the application market is as follows:
1. Communication products
2. Computer products
3. Consumer electronics
