Custom doorbells are what you want them to be. Maybe a distinctive doorbell chime just suits your personality. Maybe the sound of the traditional "ding-dong" sends the dog into a frenzy of barking. There is no right or wrong. There are choices, however, when it comes to installing or replacing one. Custom doorbells are nothing more than another way of making yourself feel at home in your home.

A Little More about Custom Doorbells

We take doorbells for granted, so much so that door knockers sometimes seem archaic. Whether we're talking about traditional or custom doorbells, the principle is the same. They work on the simple principle of electromagnetism. That is, when you press on a doorbell button, you close a circuit. Household current then flows into the electromagnet. The magnetic field then drives the noise-making mechanism.

The noisemaker will be a buzzer, a chime or a bell. The buzzer and the bell type cause a metal strip to move. The doorbell sound is when the metal strip strikes, in the buzzer, the magnet, or, in the bell, a metal bell. A chime doorbell uses an electromagnet called a solenoid, which has a piston instead of a metal strip, and the piston strikes two tone bars. Presto, you have a doorbell sound. The tone bars are what determine the type of sound you hear.

Custom doorbells can mimic virtually any simple series of notes. You might want the sound of Big Ben, or a dog barking, or a foghorn. Maybe several notes from a Mozart sonata is more your style. There is no right or wrong. There is only answering the door.
