SMD buzzer tells the production process of electromagnetic buzzer?

2020-10-22

The electromagnetic buzzer is composed of an oscillator, an electromagnetic sensor coil, a magnet, a diaphragm that affects vibration, and a housing part. When energized, the audio signal generated by the oscillating current flowing through the electromagnetic coil generates a magnetic field. The diaphragm periodically vibrates when interacting with the electromagnetic coil of the magnet.

SMD Buzzer Small Class Explanation: Several Types of Failure Causes of Instrument Types?

2020-10-20

We must have seen the instrument buzzer in the car, and the place where the car is used is different, the size and the size are different, the prompt sound and the reversing buzzer are very different. In fact, after they have been used for a period of time, there will be faults that can be large and small. At this time, we need to analyze their data and effectively solve the management according to different faults.

If the passive buzzer does not sound before installation, this is definitely a quality problem of the buzzer itself, just contact the manufacturer directly.

SMD buzzer buzzer drive circuit problem?

2020-10-12

The buzzer is an electronic buzzer with an integrated structure. Its power comes from DC voltage. Widely used in computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers and other electronic products audio equipment. The buzzer drive circuit generally consists of the following parts: a transistor, a buzzer, a freewheeling diode and a power filter capacitor.

SMD buzzer describes several common fault causes of instrument types?
