How can a speaker or active buzzer be connected to the Arduino 2560/RAMPS 1.4 boards to provide alerts in response to M300 commands in the g-code

My Prusa i3 does not appear to have any sound device incorporated. I've read "Writing G-Code: Audible Alert at end of print" and it seems everything needed to implement audible alerts is built into the G-code syntax and firmware but my rig appears to be lacking the necessary noise maker.

At least on my Ender 3 V2, the speaker is on the LCD control board and not on the mainboard itself. – agarza Sep 12 '22 at 15:38
There is no LCD unit on my printer, nor an SD card reader. It's directly connected to a PC. – allardjd Sep 12 '22 at 19:42
