Q1:Can I get free samples before mass production?
FUET: We would to send you free samples for your quality evaluation. You just need to bear shipping cost.
Q2: What's the minimum order quantity?
FUET: MOQ depends on products.please contact us to check.
Q3: What's your lead time?
FUET: Samples order 3 days;Bulk order roughly 10~20 days.
Q4: Should I choose magnetic buzzers or piezo buzzers?
FUET:Magnetic 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.
Q5: Should I choose passive type or active type regarding buzzers?
FUET:Acoustic vibration is produced by alternating current or voltage, which implies buzzer’s power input has to be alternating current, which serves as audio signal as well. For passive type, clients power them with AC audio signal generated by external audio modules or oscillators; For active type, since they have built-in oscillator with fixed frequency, clients power them with DC power source. The DC source is later processed into AC audio signal by transducers’ built-in circuits.Thus, if clients provide AC audio signal, then we recommend passive type; if clients provide DC power source, then we recommend active type.
Q6: How to design a driving circuit for buzzers
FUET: Please contact us to provide Circuit diagram reference.
