My name is Jesse Milstead of Lackey high school and my engineering team and I are desiging/creating a tracesable arrow using both a knock that lights up and a very small speaker. The speaker part is what i need your help with, we need a speaker 3mm or smaller and it doesnt matter how long it is. But the smaller the better in this case since we need to not mess with balance of the arrow as much as possible.

Thanks,

Jesse and JCD Engineering

good luck on your search, but you really aren't in the right place for that.

Piezo electric buzzers (the things that beep in computers) are small.

Can one buy balanced armature drivers without buying an IEM? One of those would do.

They wouldn't really create much of a noise without being trapped in an ear canal.

This just proves there's always a sensible answer at Head-Case.

Shrimp Dhik IEMs would be ideal for folks with slender ear canals.

Yeah, and the Pencil Dhiks came to mind too.

You should talk to guys who design mobile phones. They use itty bitty litttle board-mounted speakers.

Unfortuanately, we don't have anybody like that here. There are forums chock full of such people, tough.

So would you know forums that would be helpful?

Kids nowadays.

They want everything delivered on a platter.

Maybe he can grow an ear on the back of a mouse like they used to do.

Good grief. Just carve a notch in the arrow so that it whistles and quit trying to be all fancy. Now then, I'm done being a lackey for the lackey high students.

I'm shocked you even got a half-serious answer from anyone here. Time to leave before we drop your ass like third period French.

Wow, good thing you didn't get drop and french mixed up!
