Image of CUI Devices Buzzer Overview - Transducers V Indicators

As mentioned earlier in the presentation, piezo and magnetic indicators have the driving circuitry built into the design, creating a “plug and play” solution. Because of this, engineers do not need to worry about building a complex circuit to drive the buzzer. The disadvantage, however, is that indicators operate on a fixed frequency, reducing the flexibility offered to achieve an alternate frequency as application requirements change. Transducers, on the other hand, do not have the driving circuit built-in, so engineers are offered a greater range of flexibility when designing a circuit. The downside comes in the fact that transducers do require an external driving signal to operate properly, potentially adding complexity and time to the design cycle.
