The chime comes from Ring video doorbells, the smart doorbells that pair a camera and motion alerts with a doorbell button for homes. As the devices became common on porches in the United States and elsewhere, their electronic ding dong became as recognisable as a phone ringtone. Clips of deliveries, visitors and porch camera footage shared online helped cement the sound, and creators now borrow the recording itself for pranks, sketches and fake arrival moments where an instantly understood doorbell cue is needed.
