I noticed that we currently don't have a tag for a buzzer / beeper.
What is the first thing that comes to your mind when you see the encirceled part?
Is this a buzzer or a beeper?
- something else
Depending on the votes I would then add a tag
beeper to the devices equipped with such a hardware feature.
Devices in the OpenWrt wiki with buzzer / beeper (any others?):
- devolo WiFi pro 1750e
“Buzzer”, to me, is fixed tone. Apply power, it buzzes. “Beeper”, to me, requires a modulated signal.
Meh, the more I think about it, the less attached I become to any of them. Even "speaker" vs. "piezo transducer" doesn't cover it. Just pick one...
It doesn't really matter, as long as it's consistent. Anyone looking for a device that can beep will soon find out what it's called in OpenWrt.
On wikidevi.com there is a flag 'buzzer'; 'speaker' is used for normal audio loudspeaker.
The Linux kernel module is
pcspkr; the OWrt kernel module says 'beeper' (
kmod-gpio-beeper). There isn't much consistency in other hardware – a quick look through motherboard manuals shows 'Speaker' and 'Buzzer' about even.
No wonder you wanted a vote!
I think I'd go with 'buzzer', just to be the same as wikidevi.
If you quickly switch power off and on and if you play with the pulse with this could also become a modulation.
Checking the number of search results for "piezo buzzer" vs "piezo beeper" speaks a rather obvious message in favour of buzzer.
That has historic reasons, originally x86 hardware had a real pwm controlled speaker - only after soundcards became prevalent (and onboard), these were replaced by cheaper (mostly-) single purpose buzzers.
This topic is 3 days old.
For the fun of it:
What makes buzzing / humming sounds?
A transformer (50/60Hz) https://youtu.be/Nc8Rwj3e0gc?t=73
A hummingbird (75Hz) https://youtu.be/0vgRYTPV9qU?t=3
A bee (200Hz) https://www.youtube.com/watch?v=KG8f-EV8vDo

OpenWrt forum: 7 buzzers / 2 beepers
aliexpress: 31.000 buzzers / 1500 beepers (incl. pagers)
google: 65.6E10 buzzer / 5.45E10 beeper (incl. pagers)
Since the whole world (OpenWrt forum, google, aliexpress) thinks that a piezoelectric sound converter which makes sounds in the kHz range is called a buzzer, we will call it the same in the wiki.
