This general-purpose little speaker is great for adding high-fidelity sound that can bring your project to life (or to annoy your friends and family with loud sirens and squawks!). If you have the space and an adequate driver for it (we were able to get decent polyphonic results with just a small MOSFET controlled from a microcontroller PWM line), you can really get much more volume and richness than you can from smaller speakers and buzzers.
The speaker’s specifications can be found in its datasheet (162k pdf).
