We used the buzzer CT-1205H-SMT-TR for production, and found that around 80 pieces out of 500 pieces was with low SPL issue, using 2.4KHZ square wave, 50% duty ratio, 3V peak to peak to drive for testing, the defective is around 76dB while the good is 99dB, we would like to know what caused this problem, we can send you some sample for further analysis.
