The guest at your door pressed a button and you can hear that very familiar Ding Dong sound to realize someone is here to visit. This basically takes not more than a couple of seconds. However, the whole approach of your doorbell to create that sound, if we talk about it then clearly, it’s not going to happen within seconds.
So, let’s talk about something that not much of us think deeply about. I’m referring to the entire process of how does a doorbell work. Keep on Reading!
Let’s Figure Out How Does A Doorbell Work
The life simplifying doorbell has a lot of parts inside it that work combinedly to make that sweet sound of arrival of a loved one. It’s only fair to talk in segments about each of these parts including how they contribute to the entire process. So, Let’s Make It That Way!
The “Heart” AKA Electromagnet Of A Doorbell
Most types of doorbells will have this one part that is often referred to as its heart. And it’s called an electromagnet. A part is known as magnetic metal this wrapping coil of wire. And this coil of wire is basically the electromagnet. This metal has a different formation, however. In a doorbell chime box, it’s like a piston.
Using a magnetic field to power things, the electromagnet basically functions. Once the electrical current runs through a wire, this field starts initiating. The effect begins to amplify whenever this wire is coiled. Similar to all magnetic field’s characteristics, this one tends to flow between the south and north poles.
When a person holds the doorbell button, a signal to the transformer travels in the form of the household electrical current. This current gets low from standard 120 volts to 10 volts because of the function of the transformer. After lowering, the current passes through the electromagnet wires. And that basically triggers magnetic field creation while powering the piston.
The Piston In A Doorbell
In most discussion related to how does a doorbell chime work, there’s a part majorly talked about known as a piston. With chime doorbell boxes, a special electromagnet type is usually in charge. This part is the solenoid. If there’s a solenoid then the magnetic metal is in form of the piston. Because of the magnetic field, this piston moves back and forth.
Using iron core, this piston is made inside the chime doorbell box. This further connects with a metal rod of non-magnetic type. During the resting period which means the doorbell is not pushed, there’s no electricity current that passes through the coiled wire. On the other hand, after pushing the button, a spring forces the piston to go on the left side. And that leads the iron core to protrude coiled wires outside part.
Ding To The Right, Dong To The Left
Next to the right side of an iron core, a tone bar rests. When iron core slides to the right side through the wire coil, it hits the tone bar. And this creates vibration here. The vibration basically refers to a musical note “Ding” that we hear in the doorbell.
The electricity flows through the wire coil and at the same time piston stays in contact with the right tone bar. As soon as you release the doorbell, the flow gets ceased. And that makes the magnetic field collapse. As a result, the piston slides back to the left side. Here another tone bar gets hit by the piston. And once again a vibration comes to play that creates the “dong” sound we hear next.
What About The Wireless Doorbells?
Quite dissimilar to the regular style, there’s another version of the doorbell that you may see pretty often. And it’s the wireless doorbells. Here you don’t require to worry about any wiring. A battery and electrical system hook up will be necessary, however.
The main reason why some people prefer wireless technology compared to wired style is that it makes a very clear sound that can be heard even when you are far away. Here’s how things work with a wireless doorbell.
Once someone pushes the button, a radio signal starts transmission. Here a push switch basically stays mounted on the door. And a battery-powered ringer goes from one room to another. There’s a receiver as well that will pick the signal. And then it triggers buzzer, light, or chime of the doorbell.
To lessen the chances of disruption from nearby doorbells, some models include variable frequencies. A recorded digital sound transmits after pushing the button. This button operates through battery power. The switch basically plays the role of a transmitter for sending radio signals. Here the distance can be up to 300 feet.
Once the signal reaches the inner side, a sound-emitting happens. A wall outlet is present for plugging this ringer, receiver, or speaker. You can use one from several radio channels with a wireless chime. And that will help you to avoid mix up with your neighbors’ doorbell. Apart from the basics, there are several wireless doorbells available in today’s market with visual signals along with audible offerings.
