Tell us about the structural principle of the buzzer, what are the common faults of the buzzer?

The structure and working principle of the buzzer:

1. Structure: the buzzer is usually composed of a diaphragm, a driving circuit and a resonance chamber.

2. diaphragm: diaphragm is the vibration part of the buzzer, usually made of metal or plastic, with elasticity.

3. drive circuit: the drive circuit will provide current to the diaphragm, so that the diaphragm vibration. 4. resonance chamber: resonance chamber.

4. Resonance chamber: The resonance chamber is the cavity inside the buzzer that amplifies the sound produced by the vibration.

5. principle of operation: when the current through the diaphragm, the diaphragm will be subjected to electromagnetic force and produce vibration. The frequency and amplitude of the vibration causes the air to oscillate, which produces sound. The resonance chamber amplifies these sounds, making them clearer and louder.

Common Failures:

1. diaphragm damage: as the diaphragm is the core component of the buzzer, if the diaphragm is damaged or aging, it will cause the buzzer to not work properly.

2. drive circuit failure: drive circuit components are damaged or connection problems may lead to the current can not be properly transmitted to the diaphragm, so that the buzzer can not vibrate to produce sound. 3. resonance chamber problems: resonance chamber problems.

3. Resonance Chamber Problems: Structural or air circulation problems inside the resonance chamber may affect the amplification of the sound, causing the sound to become muffled or not output properly.

4. Power supply problem: If there is a problem with the power supply of the buzzer, such as unstable voltage or insufficient battery power, it will also cause the buzzer to fail to work properly.

5. External environmental influences: The buzzer is also prone to malfunction when it is used in a humid, dusty or too hot environment.

When maintaining the buzzer, you need to pay attention to the above failure conditions to ensure that the diaphragm and driver circuit operate properly, and keep the buzzer clean and in a good working environment to ensure that the buzzer can sound properly.
