What are the advantages of electromagnetic buzzer? What is it like? The advantages of electromagnetic buzzer are as follows: 1. Because there is no single-sided contact, it has a long service life and high reliability. Can be used continuously for more than 10000 hours. 2. No arc, no radio frequency noise, no interference to others. 3. No large vibration caused by loosening. 4. Accept the mastery of electronic circuits and let them produce all kinds of beautiful sounds, simulated sounds, and intermittent sounds. The tone is pure and not easily whitewashed by noise.
