This electromagnetic transducer is a compact way to add sound to your embedded project: just supply it with a PWM signal at 3V to 7V / 4V to 6V  and it will produce sound at the frequency of the supplied signal from an opening on the side / top. Since the 70mA / 60mA 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.
