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.

Piezoelectric buzzer Φ17*7mm without oscillator circuit for waiter equipment

 

Description:

 

Buzzer is a signaling device that is not a loudspeaker. It can be mechanical, electromechanical, or electronic (a piezo transducer).

 

Piezo buzzer is an electronic device commonly used to produce sound. Light weight, simple construction and low price make it usable in various applications like car/truck reversing indicator, computers, call bells etc.

 

A piezo buzzer generates sound because of the piezoelectric effect from the piezoelectric ceramic which drives the metallic diaphragm to vibrate. We suggest inputting higher voltage for a piezo buzzer, normally over 9V to have enough SPL.

 

There are two main types of buzzer: active and passive.

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.

 

Feature:


• They feature extremely low power consumption in comparison to electromagnetic units.
• Because these buzzers are designed for external excitation, the same part can serve as both a musical tone oscillator and a buzzer.
• They can be used with automated inserters.Moisture-resistant models are also available.

• The lead wire type with both-sided adhesive tape installed easily is prepared.

 

Application:

 

• Medical equipment: glucose meter for blood, temperature test instrument, ECG monitor, fetal heart tester, blood glucose meter

• Home appliances: refrigerator, washing machine, computer, air conditioner, telephone, microwave oven, oven, TV set, keychain

• Electronic products: mobile phone, remote control, anti-lost device, POS machine, electronic toy, robot, watch, facial massager, instruments and apparatuses, unmanned aerial vehicle

• Security equipment: warning lights, anti-theft electronic locks, safety equipment and sirens/alarms/car alarm.

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.

• Be careful not to drop the piezoelectric buzzer.
