Description:
A Piezo transducer can produce the sound for panel mount buzzers, household goods, medical devices and even very loud sirens.
When a lower frequency is required, an electromagnetic buzzer can fill the need. These are very common in automotive chimes and higher end clinical diagnostic devices.
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.
