2. Should I choose transducers or indicators regarding buzzers?

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 transducers, clients power them with AC audio signal generated by external audio modules or oscillators; For indicators, 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 transducers; if clients provide DC power source, then we recommend indicators.
