What is Speaker in Computer – An Introduction
Published: 26 Jan 2026
Have you ever asked, “What is speaker in computer and how does it work?” Many people get confused between input and output devices. Computer speakers are not for typing or touching they are only for sound. They let you hear music, notifications, and all other computer sounds.
What is Speaker in Computer?
A computer speaker is a hardware device that changes digital signals into sound. They allow you to hear music, notifications, videos, games, and other audio. In simple words, speakers are what make a computer talk. Speakers are not input devices. They only give sound to users, which is why they are called output devices.
Importance of Speakers in Computer
Speakers in a computer are very important because they help us hear sound clearly. They are computer output devices that make music, videos, alerts, and games enjoyable. Without speakers in a computer, we would not be able to listen to sounds or notifications from our system. They are simple to use and improve the overall computer experience.
Parts of a Speaker
A computer speaker has different parts that work together to create clear and loud sound. Each part has a special function to make the sound better. Here are the 10 parts of a computer speaker explained in complete detail for beginners.
- Cone
- Magnet
- Voice Coil
- Dust Cap
- Spider
- Surround
- Basket
- Terminal
- Tweeter
- Casing
1. Cone
The cone is the main part of a speaker. It moves back and forth to produce sound waves. The cone is usually made of paper, plastic, or metal. The size and material of the cone affect how loud and clear the sound is.
2. Magnet
The magnet works with the voice coil to move the cone. It creates a magnetic field that helps the cone vibrate. Stronger magnets produce louder and better sound.
3. Voice Coil
The voice coil is a wire coil inside the speaker. It receives electrical signals from the computer. When electricity passes through, it moves the cone with the magnet to create sound. The voice coil is very important in every computer speaker.
4. Dust Cap
The dust cap covers the center of the cone to prevent dust and dirt from entering. It also helps in keeping the sound smooth. Small dust caps are found in both internal and external speakers.
5. Spider
The spider is a flexible ring under the cone. It holds the voice coil in place and allows it to move freely. The spider helps the cone move without getting stuck, giving clear sound.
6. Surround
The surround is the soft edge around the cone. It helps the cone move back and forth and keeps the sound smooth. Without the surround, the cone could not produce proper sound.
7. Basket
The basket is the frame of the speaker. It holds all the parts together like the cone, magnet, and voice coil. Baskets are usually made of metal or strong plastic.
8. Terminal
The terminal is where you connect wires to the speaker. Terminals link the speaker to your computer or audio device. Proper connection is important for clear sound.
9. Tweeter
Some speakers have a tweeter, a small part that produces high-frequency sounds like bird chirps or cymbals. Tweeters make music and games more detailed and enjoyable.
10. Casing
The casing or enclosure protects all the internal parts of the speaker. It also helps the sound spread better. External speakers usually have larger casings for louder sound, while laptop speakers have small enclosures.
How a Computer Speaker Works
A speaker plays sound from your computer. Here’s an easy way to understand how it works:
- The computer creates sound data, like music, voice, or game sounds.
- This sound is sent to the sound card.
- The sound card changes the digital signals into analog signals.
- The computer sends these signals to the speaker.
- The speaker uses power to make the sound louder.
- The speaker cone vibrates to produce sound waves.
- These sound waves travel through the air.
- We hear the sound clearly through the speaker.
- External or internal speakers work in the same way.
- Speakers make the computer experience fun and interactive.
How to Connect Speakers to a Computer
A computer speaker lets you hear music, videos, games, and alerts. To enjoy clear sound, you need to connect your speakers correctly. Here’s a simple guide to do it.
1. Using a 3.5mm Audio Jack
Most computers and laptops have a 3.5mm headphone port. To connect the speaker, use a 3.5mm audio jack. Take the speaker cable with a 3.5mm plug and insert it into the audio-out port of your computer. Turn on the speakers and adjust the volume. This method works for both internal and external speakers.
2. Using USB Connection
Some speakers connect via USB. To connect the speaker using USB, plug the USB cable from the speaker into a USB port on your computer. Your computer may automatically install the required drivers. Turn on the speaker and check the sound. USB speakers are usually powered directly by the computer.
3. Using Bluetooth (Wireless Speakers)
Modern computers and laptops support Bluetooth speakers. To connect a Bluetooth speaker, turn it on and open the Bluetooth settings on your computer. Select your speaker from the list of devices, pair it, and check the sound. Wireless speakers are portable and easy to use, with no cables needed.
4. Check Speaker Settings
After connecting, make sure the speaker is powered on. The computer volume is up. The correct audio output device is selected in your computer’s settings.
