Buzzer device test
CRYSOUND Buzzer Tester can be used to test the electroacoustic parameters of active electromagnetic buzzer/passive electromagnetic buzzer/active piezoelectric buzzer/passive piezoelectric buzzer (frequency response curve, Fc reference frequency, F0 resonance frequency and other indicators). Such a buzzer tester has supporting interfaces for automatic equipment, so it is suitable for the integration of various automation systems. It is equipped with a CRY582 buzzer test box, which converts positive harmonic signals into square wave signals to achieve output signal amplification and adjustable output duty cycle, so greatly improving the buzzer test accuracy.

Passive piezoelectric buzzer test path
CRY6151/CRY6151B outputs sine wave signals
CRY582 Buzzer Tester converts sine wave signals to square wave signals and amplifies the signals
The square wave-driven buzzer produce sounds (10K resistor in parallel with the test terminal)
The measurement microphone acquires and inputs the sound signals into CRY6151/CRY6151B for analysis
Passive electromagnetic buzzer test path
CRY6151/CRY6151B outputs sine wave signals
CRY582 Buzzer Tester converts sine wave signals to square wave signals and amplifies the signals
1/2 square wave-driven buzzer produce sounds
The measurement microphone acquires and inputs the sound signals into CRY6151/CRY6151B for analysis
