What is the name of this electronic component?

RejZoR · Feb 8, 2017

I know this is a speaker of some sort, it has a magnet surrounding a coil and with a metal plate on top, but I have no idea how these are officially called. I have this device which stopped beeping when you press a button and I'm thinking it's just this speaker that died. Replacing it should be fairly easy on such large PCB. I'd just have to figure out if there are any voltage limitations or what voltage even is used here...

That's a piezo buzzer

Yeah, looks like a piezoelectric speaker: https://en.wikipedia.org/wiki/Piezoelectric_speaker

A while ago we had a multi fan controller from zalman with a display and after several years we were unable to change the fan speeds,
on some inputs were no fans plugged in resulting at 0rpm and it ended up in a constant alarm beeping noise,
I took the fan controller apart and broke of that exact speaker you are showing, the alarm noise stopped ofcourse.

Maplin will have one of them

As others have said, can be found on some motherboards too now saving you from the dreaded 90's and having that little speaker on the front of the case

.

Sasqui · Feb 8, 2017

Some cases (or motherboards?) come with those, two wires leading to a standard jumper that pops onto a motherboard header.

I want a series of these for an alarm clock. That would be fun.

cornemuse · Feb 8, 2017

On a mobo I have/had? its printed (on mobo) next to this same item: 'Buzzer'.

And yet i have never heard one buzz, beep sure but not buzz

This isn't piezo based. Piezo is folding 2 combined elements by introducing current to it and that create soundwave. This thing actually has a coil inside and the membrane is not paper/rubber but a thin metal plate. So, technically it's closer to an actual speaker than piezo squeaker...

Someone needs to do a mod for 5.1 system with those

They go by many names and manufactures and many applications. PC speaker, motherboard speaker, buzzer, Rino AS01 Mott

Its more of a beep than a buzz but it is a speaker

slightly off topic

In the past days when laptop's had no sound
you could load a prog( Driver) to use pc speaker as low grade sound

Any one else remember that ????

My friend from school had an old i486 which was not capable of mp3 playback. He used that driver to run low-bitrate music through the buzzer.
And a PC at my mom's work only had a floppy drive (I only bought mine in college), so I used to downsample music to 96kbit/s mono and bring it on a pack of floppy disks.
Yes, we were that broke... :banghead:

I think piezoelectric speakers don't have coils nor magnets :confused:

Exactly.

386dx with 120 meg hdd 4 meg ram, First music I ever heard on this comp was a very low quality download of "Keep on Truckin'" = Grateful Dead, over that tinny lil speaker, , , , , 28.8 modem took prolly half the night to d/l!

RejZoR · Feb 9, 2017

The reason why I need an actual name is so that I can order this thing. If I don't know what I'm even looking for by name, I can't even find it.

Ebo · Feb 9, 2017

I allways just said, a little black speaker to put on the motherboard, then they have allways known what I was talking about.

eidairaman1 · Feb 9, 2017

POST Buzzer, Modem Buzzer lol

There is one, in first post...

blobster21 · Feb 9, 2017

This little component did quite the buzz....

alucasa · Feb 9, 2017

I used to call it "The bitch's hole" ....

I don't see it anymore on recent mobo anymore.

RejZoR · Feb 9, 2017

This is from air purifier unit, so not a computer. Device still works, but when I press buttons, it doesn't beep anymore and it's a bit annoying since I don't get any touch feedback from it, meaning I have to look at the screen on top...
