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?
