Am trying to find a 12VDC audio device that can fit to an alarm system. Want it so that can load it about a minute sound bite of say a dog barking or a voice warning. There must be something on Ali Express but damned if can track down anything.

 

Just that many decades ago at our crib/batch we had one of those big sound blasters with an endless tape with a recording of a vicious dog. It was hooked up to one of the earliest light sensors. Friends who used the place were terrified arriving, even knowing what it was!

 

Thanks for any suggestions.

Adafruit Audio FX Mini Sound Board - WAV/OGG Trigger - 2MB Flash [ADA2342] might do the job for you. Its 5vdc but should be able to step down to that from your 12vdc. Should be able to trigger it from alarm output or sensor output. About $30 plus shipping from Amazon.

Thanks for this and am sure I can find someone to put it all together with the speakers.

Would you have any idea what size speaker it could run (outside use)?

 

Thanks

Not sure as only 2watt amp, but its not bass you’d by putting out, so may be ok.

I have the original with normal line out, so can plug into any amplifier and speakers,

The other cool thing with this fx board, you could load different samples (dog sounds) and can configure so its not always the same sound byte each time its triggered if you should choose.
