Speaker

The speaker is an output device of the computer. Speakers are used for sound sharpening in computers. Speakers are currently one of the most important parts of multimedia PCs. Many PCs have built-in sound processors and speakers. Most users use external speakers. This is because the audio quality of these is very good and the amplifier is connected so that the volume can be controlled by hand. Many people nowadays use high-end subwoofers and 3D surround sound speakers for better quality sound. The speaker's input jack has to be placed on the sound card jack on the back of the computer casing.

Use of Speakers

Speakers are used in the following cases, such as -

  • Used in telecommunication equipment,
  • Used to generate sound waves in radio and television,
  • Used to convert amplified electrical energy into human audible sound energy,
  • Used to generate human audible sound in public address systems, tape recorders, computer amplifiers, and so on.

Before Buying a Speaker

Before buying a speaker, you need to know what kind of speakers your computer supports. Usually, it is 2: 1, 4: 1, 5: 1 or 6: 1. If you want to play the speaker through wireless Bluetooth from the smart device, you have to buy a speaker that has Bluetooth facility. There are many speakers that can play sound from a pen drive or memory card, you can buy speakers with this facility if needed. Make sure you have a sound control system.

Specification

At the time of purchase, you will see that the specification of the speaker is mentioned on the package. Watt, frequency, signal ratio, input-output system are written. If you know the meaning of these, you can decide for yourself which speaker is better for you. Frequency ratios are usually calculated in Hertz. The higher the number, the more noise the speaker can generate.

Sensitivity

Sensitivity is expressed in decibels per watt. This indicates how much noise a speaker can make per watt.

Calculation of Power Consumption

Watt power consumption is usually calculated. It indicates how much electricity a speaker works on.

More conventional and more popular branded speakers should be bought. At present, D-7, Logitech, Creative, Microlab, Altech Lansing, Digital X, F&D, etc. speakers are running well in the market.

Taking Care of a Speaker

It can be seen that the speaker often ruins after a few years. If you want to keep the speaker good, you have to take care of it regularly. If you are aware of before and after buying the speaker, you can prevent the speaker from being damaged quickly. Let's take a look at the ways to take care of the speaker-

  • The speaker should be placed in wood or any other non-magnetic environment. It should not be placed inside any metal structure where the magnetic field works. Moreover, it is not right to keep it close to any magnetic field, as it will destroy the electromagnet present in the speaker.
  • The speaker should not be placed in a place where direct sunlight falls. Rather it needs to be kept in a place where it is relatively cold. The speaker should be placed in a place where adequate light and air are available.
  • The speaker should be kept clean regularly. The speaker should be wiped with a thin dry cloth at least once a day. The speaker can also be cleaned with a blower or duster.
  • The main enemy of the speaker is dust. The speaker may become useless due to dust accumulation. So the speaker should be placed in a place where there is relatively less dust.
  • A good quality multiplug must be used to provide uninterrupted power supply to the speaker. Using a faulty multiplug can also have a detrimental effect on the speaker.
