Q: What is a passive magnetic buzzer? A: Passive buzzers cannot sound directly by DC power. They need square wave signal from MCU or drive circuit to make sound.
Q: What is the difference between passive buzzer and active buzzer? A: Active buzzers have built-in drive circuit and sound once connected to rated DC voltage. Passive types need external drive and support adjustable sound frequency.
Q: Can this buzzer work in low-temperature outdoor equipment? A: Yes, its operating temperature covers -40℃ to 85℃, which fits outdoor and industrial low & high temp environments.
