Video details

A customer's production line stopped for three days because every buzzer test station showed a failure. After testing the buzzers, we found that the components were working normally. The real problem was the mismatch between the drive frequency and the buzzer's working frequency: Drive frequency: 20 kHz Buzzer working frequency: ~2.7 kHz The buzzer itself wasn't defective. The test signal was simply incorrect for the selected buzzer. After matching the correct buzzer with the appropriate drive frequency and test settings, the production line restarted the same day. The lesson: When a buzzer fails during testing, don't immediately assume the component is defective. Check the drive signal, working frequency, voltage and test conditions first. At HNDZ, we provide electromagnetic buzzers, piezo buzzers and customized buzzer solutions, with technical support for buzzer selection and application matching.
