This electromagnetic transducer is a compact way to add sound to your embedded project: just supply it with a PWM signal at 4 V to 6 V and it will produce sound at the frequency of the supplied signal from an opening on the top. Since the 60 mA maximum current draw is higher than what can be supplied by a typical microcontroller I/O pin, you will probably want to control it with a suitable driver, such as a small MOSFET.

We also carry a similar buzzer with a side opening.

For an example buzzer circuit, see the schematic for the A-Star 32U4 Prime.
