Help me identify a buzzer sounder

[DanPBP]

Hello Guys,

It's me again with these silly questions...

This is the buzzer I'm trying to identify:



I guess it's not a piezo buzzer, it sounds different, like a little horn.

What's the name for it? Or, where can I find it?

Thanks!

Daniel.

I'm pretty sure it's just a little speaker. I have one or two around here somewhere. I'll dig around and see if I can find one to refresh my memory.

I got them at radio shack about 20 years ago....

This company may sell world wide.
I have bought from them, they have a medium rating on the “Adam’s scale”.

Well, I didn't find the one I was looking for, but I found something similar. This one claims to be an "electronic chime, and it's Archer (radio shack) part # 273-071.
It LOOKS a lot like the one you showed, but it sounds different.

Close examination shows that this one definitely has a small speaker in it. And obviously there's also a bit of electronics to make it "chime". Yours is probably similar, it's just designed for a different noise.

Here's photos of the one I have:




Note that this one has 3 wires. Black and red are + and - in, and the white one "enables" the noise when pulled high.

It makes a kind of musical 2-tone "bing - bong" sound. I was going to record it for you, but my recording apparatus seems to be broken today.

Anyway, I'm sure that the one you have is similar... a little speaker with some small electronics to drive it. I still think I've got one like the one you showed around here somewhere, but I couldn't coax it to the top of the pile. If I find it I'll post a part #.

Hey Guys,

Thanks for the info!!! I wanted to show you another buzzer I got (the one at the bottom):



They look the same, but the sound is different... And, this is how it sounds (this is not what I'm looking for):



One thing about the first one, it actually vibrates when it's turned on, like an electromagnet bell sort of thing...

Thanks!
