How to test active piezoelectric buzzer?
The function signal generator, the power regulator, the decibel meter and the triple meter should be used in the test. When the user enters the material inspection, according to the buzzer specifications provided by our company, For example, if a customer uses our product ZL-YDY2416-2812P-15, the rated voltage is 12Vdc, the frequency is 2.8KHz, the test distance is 30cm, the minimum sound pressure value is 90dB / min, the maximum current value is 15mA / max.
Test connection as shown below:
1. Measure the buzzer current value (mA).
2. Measure the sound pressure value (dB) of the buzzer.
3. Measure the frequency of the buzzer (KHz).
