Description
Each 'item' you buy gets you 5 x 16Ohm Universal Passive Buzzer / 2KHz S749
A continuous voltage will not cause this to make any sound. It needs to be modulated at whatever frequency you want it to emit.
You should also be able to use this as a microphone. I haven't tested it, so I don't know the quality (let me know if you test it so I can inform others). However I could see a waveform being generated on my oscilloscope when I yelled into it.
These are 11mm in diameter, and the pins are 7mm spaced
I am unsure what the max voltage is. But I would recommend using 5V or less for this.
