I need to build one that can be used outdoors.

Where can I find the schematics for this kind of circuits?

    Like single frequencies/tones (beeps, boops)? Or more complex sounds (dog barking, voice)? A little more specifics about your project would help us give better info.

        It sounds like you are looking for something like this: https://www.adafruit.com/product/2210

        If you look around the site, there are lots of helpful tutorials to get you started with it and also help you adapt it to your needs. They also sell most of the extra parts you would need. For example you could add this to make it motion triggered. Their parts aren’t the cheapest tho, you are paying for the ease of use, excellent documentation, and tutorials. If you’re crafty, most of it should be salvageable from e-waste.
