There are two main types of buzzers, namely magnetic buzzers and piezo buzzers. In general, magnetic buzzers are more traditional. Compared with piezo buzzers, their composition is more convenient. When a voltage is applied, the coil of the buzzer generates a viable magnetic field, which makes the diaphragm produce sound. The magnetic buzzer type is mainly a low voltage of 12V. It also has high current consumption. The magnetic use of this buzzer is ideal for different applications requiring low voltage levels. In this blog post, manorshi focused on the key functions of magnetic buzzers, including a brief analysis of magnetic buzzers and piezo buzzers.
Before anything else, you should understand the structure of the magnetic buzzer in detail. In this paragraph, you will gain the following knowledge:
The magnetic buzzer has a coil. It is located in the circuit of the device. The same circuit has permanent magnetic characteristics and is connected to a permeable disc made of metal. The disc is attracted by the magnetic field.
Therefore, when the oscillating signal moves into the coil, a magnetic field is generated, which causes the internal diaphragm to vibrate rapidly. This usually happens at high frequencies. Having said that, the piezoelectric buzzer is just the opposite. Here we mean that the electroacoustic generator has a simple ceramic disc. The element has a unique metal plate connected to a ceramic layer.
Like piezo technology buzzers, transducers and indicator configurations include magnetic buzzers. The buzzer's transistor is the driving circuit. Some indicators of magnetic buzzers include sounds, especially when a DC voltage is applied.
When it comes to sound production, magnetic buzzers have sound sensors. These components are commonly used in certain enclosures, especially when there is a resonant cavity in the sounder. The device can meet certain requirements to some extent. For example, to obtain an increased sound pressure, the voltage of the present invention needs to be increased. The vibrating disk found in the electromagnetic buzzer is attracted by the magnetic field. When the oscillating signal moves towards the coil, it emits a fluctuating magnetic field. This will cause the disk to vibrate.
1.Which buzzer should you choose?
When looking around for buzzers, the capabilities of the device must be considered. Confirm the electrical and physical parameters required for the equipment. In addition to this, you should also look at the buzzer's frequency, operating voltage, and resonance. These are the main factors to consider when choosing between a piezo buzzer and a magnetic buzzer

The center of the piezo buzzer is the famous piezo element. This feature has a ceramic plate bonded with an adhesive. The side has electrodes for enhancing conductivity. Finally, when choosing between a magnetic buzzer and a piezoelectric buzzer, you should focus on the function of the buzzer.
