The buzzer is a kind of electro-acoustic component, which is used to make voice to alarm or prompt. For example, the alarm sound of the host induction cooker and the computer start-up sound. In general, various electronic products, there are a simple beep sound is usually sounded by a buzzer.
Different Types of Buzzers
So what kinds of buzzers are there? We categorize the buzzer according to the working principle, driving method and connection method, and then we will explain it according to various classification methods.
The working principle here refers to the sounding principle of the buzzer. We can divide the buzzer into two types, one is piezo buzzer, the other is magnetic buzzer. The sound of the piezo buzzer is based on the characteristics of the piezoelectricity, and the sound principle of the magnetic buzzer is electromagnetic induction.
The driving method is classified according to the different signals that drive the buzzer. The self-excited buzzer is driven by a DC signal, and the externally excited buzzer is driven by an AC signal.
The connection method refers to the connection method of the buzzer and the PCB board, which is divided into 3 types, DIP type, wire type, and SMD type.
Based on the above, we can know that the buzzer can be roughly divided into 12 different types by working principle, driving method, and connection method. Our website is simply divided into, the five types, piezo buzzer(self-drive), piezo buzzer(external-drive), magnetic buzzer(self-drive), magnetic buzzer(external-drive), and SMD type buzzer, so users could easily to fine what they need. In the following articles” The Difference Between Magnetic Buzzer nd Piezo Buzzer”, we will give a more in-depth explanation of different types of buzzers.
