A long time ago, people have to stand outside the door and shout the occupant’s name for a long time before the door is opened for him. The doorbell was then developed and isdesigned as a signaling device placed near a door. These door bells emit a ringing sound that is used to alert the residents of a house or building tenement to a visitor’s presence as soon as the visitor presses the doorbell button. The modern electric doorbell actuated by an electric switch was invented by Joseph Henry in 1831 and the device has evolved into one of the most important in the house today.
