Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.

piezo electronic buzzer


alarm piezo buzzer

12*12*3mm AC type surface mounted 4000HZ 3V piezoelectric buzzer SMD




As a type of electronic buzzer with integrated structure, buzzers, which are supplied by DC power, are widely used in computers, printers, photocopiers, alarms, electronic toys, automotive electronic devices, telephones, timers and other electronic products for voice devices. Buzzers can be categorized as active and passive ones.


An active buzzer has a built-in oscillating source, so it will make sounds when electrified. But a passive buzzer does not have such source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it. The active buzzer is often more expensive than the passive one because of multiple built-in oscillating circuits.




Widely used in quartz crystal clock, air-conditioner instrument, telephone, BP, copycat, alarm, instrument and apparatus, UPS power supply, motorcycle steering gear, electronic toy, computer terminal, and electronic watch.

Precautions for use:

• Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect the performance.

• Do not supply any voltage higher than applicable to the piezo- electric buzzer.

• Do not use the piezoelectric buzzer outdoors. It is designed for indoor use. If the piezoelectric buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture.

• A piezoelectric ceramic material of approximately 100μm thick is used in the sound generator of the buzzer. Do not press the sound generator through the sound release hole otherwise the ceramic material may break. Do not stack the piezoelectric buzzers without packing.

• Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like.

• Be sure to solder the buzzer terminal at 350 max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver.

• Avoid using the piezoelectric buzzer for a long time where any corrosive gas (H2S, etc.) exists; otherwise the parts or sound generator may corroded and result in improper operation.

• Be careful not to drop the piezoelectric buzzer.
