Q: Is this electromagnetic buzzer active or passive? A: It is passive magnetic buzzer. Square wave signal is required; it cannot be directly powered by DC.
Q: What is the advantage of side sound structure? A: The sound hole is on the side, suitable for product structures where the top surface is blocked and only side space is reserved for sound.
Q: What is the advantage of PPS housing? A: PPS has excellent thermal stability, can withstand higher temperature and is suitable for harsh temperature scenarios.
Q: Why use gold plated pins? A: Gold plating greatly improves oxidation resistance, guarantees stable solderability for long-term storage and assembly.
