Auto Beep Beep Beep buzzer?

I bought a 100 pack of auto flashing red LEDs that flash 1 time every second. Is there an auto buzzer that buzzes or beeps 1 time every second? What is the name of it?
 
Define once per second. The diaphragm moves once per second (sub sonic)? or it buzzes at some unnamed frequency for some time less than a second and then stays off for the rest of the second? Or something else?

And what does this buzzer have to do with the LEDs that you mentioned?
 
Put an active piezo beeper in series with the LED – with a resistor of course.

A commercial "backup alarm".
