There are many kinds of SMD buzzers with different specifications. We need to know several main parameters (voltage, current, drive development mode, size, fixed working mode of connection). Of course, more importantly, the sound we want to obtain (sound pressure size, frequency level).

what are the classification of pin buzzer buzzer introduction?

2020-09-30

The electromagnetic type buzzer mainly uses the characteristics of an energized conductor to generate a magnetic field, and uses a fixed permanent magnet and an energized conductor to generate a magnetic force to push an eardrum fixed on a coil. Due to the different sound principles of the two buzzers, the piezoelectric structure is simple and durable, but the tone is single, which is suitable for alarms and other equipment. Electromagnetic due to good sound quality, so more for voice, music and other equipment.

Pin buzzer buzzer introduction matters needing attention in the process of using?

If the starting voltage is too low or too large, it is easy to be quiet or rusty during use.

The pin buzzer describes the inspection steps for the radar not to sound during reversing?

2020-09-24

If the reversing radar does not make a sound, please check whether the power cord of the host is connected and whether there is current. Then see if the main line of the radar is loose. If there is no problem with both, the problem may be on the radar itself.

What is the structural principle of the pin buzzer?

2020-09-21

The piezoelectric buzzer is mainly composed of multivibrator, piezoelectric buzzer, impedance matcher, resonant box and shell.

pin buzzer buzzer on the drive circuit of the problem?

2020-09-18

The buzzer is an electronic buzzer with integrated structure. It is powered by DC voltage. It is widely used as a sound device in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products.
