Buzzer with new Cases?

[skyblue]

on new Cases i've been lately, they don't have a speaker in them, but there is this little Aspirin sized button with 2 wires about 1" long connected to a 4 pin plug.

i assume this is a buzzer that is supposed to replace the speaker.

is this a buzzer? and does anyone ever plug these things in? or just leave them out. thanks,
eric

Haven't seen one because I'm into old stuff but suspect what you are seeing is piezo-electric crystal replacement for speakers. Ed Fair

Yes, some do, some don't, but the little thimble sized audio thingy still beeps and doesn't buzz.
