Description: If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 0.25W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick, the same kind you might find in one of those “talking greeting cards”.

I used this combined with the Sparkfun BOB-11044 mono audio amp breakout to add a horn to my son’s pinewood derby car. Thanks to this, his car took the top trophies for “Best Design” and “Most Unique”!
EDIT: Somehow I accidentally gave this 4 stars when I meant to give it 5. It seems I can’t edit that part of the review. Sorry. @Sparkfun, feel free to correct and remove this edit note.
First the speaker does actually work, all you need to do is plug it into a function gen and i set mine to about 3.5 Vpp and it worked great. That being said the choice of wire is pretty bad. The wire is stranded and it feels like after just a small amount of use that the wire is close to breaking off of the speaker, also its very difficult to plug the male leads of the wire into a breadboard, I was able to get it to plug into female header connectors but they dont stay without you hold them. All in all I would probably recommend another more robust speaker, or atleast different connecting wires. UPDATE: Just after writing this review, having had only used the speaker for about 30 minutes one of the leads has broken off of the speaker.
Sorry to hear your units has broken. With these being only $1, there are some quality limitations. Contact us at Tech Support @ Sparkfun.com and we’ll be happy to credit you for the broken speaker.
