What is Speaker?
Speaker is a computer hardware output device, which is used to listen to the sound by connecting to the computer.
Some special types of speakers are made to connect to the computer.
While other speakers can be connected to any device.
The signals for the sound coming out of the computer speakers are created by the computer “sound card”.
IBM made the first internal computer in 1981 whose sound quality was not very good.
Most early monitors had speakers placed on the bottom right and bottom left or on the front of the monitor. But nowadays speakers are being placed on the left and right side of the monitor.
How does the speaker work?
As we said above, the main function of a speaker is that it converts electric waves into sound waves.
The speaker first receives sound from the computer or any device. This sound is either analog or digital.
If the sound received by the speaker is analog then an analog speaker converts it directly into sound waves and if the sound is digital then a digital speaker first converts it into an analog signal and then into a sound wave.
The sound coming out of the speaker is called frequency (frequency) or amplitude (amplitude). The frequency tells whether the sound produced was high or low. The quality of the sound depends on how the signals are being received by the speaker.
Amplitude measures the pressure created by the sound waves. The more pressure is given to the voice, the louder the voice is heard. In devices where the audio source is weak, speakers are used to enhance the sound quality.
What is the type of speaker?
There are many types of speakers on the basis of technology, which are explained in detail below-
1 – Sub-Woofers
Sub-woofers are very low-frequency speakers, with an intensity of sound between 20 and 200 Hz. These are used in home theatres, cars etc.

Bookshelf speakers are medium sized. These can prove to be a great option in a home theater setup. These speakers are directional, which means you have to face yourself to hear the sound properly. This type of speaker also requires an amplifier and receiver, just like floor standing.
6 – Central Channel Speaker
The quality of the central channel speaker is on par with studio monitors. These speakers are placed in front of or above the television to bring quality to the sound of the television.
7 – Satellite Speakers
Satellite speakers are smaller in size as well as wired. They already have a sub-woofer and this sub-woofer is the typical power source for them. You can install this type of speaker anywhere in the house.
