Number of personnel and breakdown of departments(RD/ Engineering/ Sales/ Operators) RD: 5,聽 Engineering: 7,聽 Sales: 12,聽 Quality: 10 3. Up to now, we are cooperating with Flextronics, Chrysler, Electrolux, Roche, Johnson Cotrols, Panasonic and so on FAQ Q: Can I have samples? A:聽Yes.Sample is surely ok. We can even send you free sample and you should only pay聽for the freight聽聽fee. Q: Should I choose magnetic buzzers or piezo buzzers? A锛歁agnetic buzzer is powered by electrical current. Its acoustic vibration is produced by electro-magnetic force, which increases as current increases. On the other hand, piezo buzzer is powered by electrical voltage. Its acoustic vibration is produced by piezoelectric force, which increases as voltage increases.Clients are advised to decide according to their circuit characteristics, and what type of energy they expect to drive our buzzers. Q: Which payment form you can accept? A: T/T, Western Union, PayPal etc. We accept any convenient and swift payment term.聽 Q: Would you have a discount if l have a large order? A: Yes we could offer different discount according to your order quantity.ChinaPiezoAlarmFactory website:http://www.czfhdbuzzer.com/piezo-buzzer/piezo-alarm/
