doorbell
Synonym discussion
Sense: noun/1
Doorbell is the everyday term for the button-and-bell system at a home's entrance. Buzzer is more common in apartment buildings, where pressing a code produces a buzzing sound to unlock the door — it suggests a harsher, electronic sound rather than a musical ring. Bell is a very broad word covering any metal object that makes a ringing sound when struck; a doorbell is one type of bell. Chime refers specifically to a musical or melodic doorbell sound, often made of multiple notes. Use doorbell for most household situations ('My neighbour rang the doorbell at 7 a.m.'), and buzzer when talking about flats or security entries ('Press buzzer 3B to be let in.').

Etymology
Doorbell is a compound word formed from 'door' (from Old English 'duru', meaning the entrance to a building) and 'bell' (from Old English 'belle', meaning a hollow metal object that rings when struck). The word has been used in its modern sense since at least the 1700s, when mechanical doorbells became common in households.
