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.

Split pin terminal type buzzer , Φ12*8.5mm AC type without oscillator circuit

 

 

Description:

 

A buzzer can be either AC or DC operated and can be mounted anywhere according to the need and purpose. When used as an alarm device, the buzzer is usually mounted on a control panel. The latest technological developments have led to using buzzers in sirens and signals for a wide range of applications.

 

A passive buzzer emits a tone when a voltage is applied across it. It also requires a specific signal to generate a variety of tones.

 

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.

Difference between piezo buzzer & magnetic buzzer:

A piezo buzzer generates sound because of the piezoelectric effect from the piezoelectric ceramic which drives the metallic diaphragm to vibrate.

A magnetic buzzer is based on the electromagnetic principle, the metal diaphragm is pulled when input the power, and spring back without power.

The piezo buzzer is driven by square waves, and the magnetic buzzer needs 1/2 square waves to drive.

We suggest inputting higher voltage for a piezo buzzer, normally over 9V to have enough SPL. On the other hand, a magnetic buzzer can be driven to generate 85 dB by only 1.5V, but the consumption of the current will be much higher than Piezo one.

To compare the two types of buzzers, the magnetic type can have lower frequency response with the same dimension.

Though being limited by the dimension, the SPL of a magnetic buzzer can only reach to 90 dB. The piezo buzzer can achieve the SPL of 120 dB in some spec., some larger size can also easily reach to 100 dB.
