What is computer speaker and its types
A computer speaker is a computer hardware output device that, if connected to a computer, converts analog audio signals into audible sound. Which is what we have heard in the end.
All of you must have seen these speakers around you, whether they are installed in your computer, or in the walls of railway stations, or in movie halls. But there will be very few of you who know what exactly Speaker is and how it works.
Just keeping this thing in mind, I thought that why should not you be provided with information about the small and big things related to the information about the speaker so that you have the right information about them and together you buy it with the right type. be able to choose. So then let’s start and know what is this speaker and how many types are there.
What is Speaker (What is Speaker in Hindi)
Speakers or LoudSpeakers are a very common output devices. They are used in computer systems. Where some speakers are designed specifically with certain computers, others can be used with any sound systems. Whatever their design, the main function of speakers is to generate audio output, which is a Common man can hear.
Loudspeakers have been used for many years to convert electrical signals into audio sound waves.
The main function of the Loudspeaker is to convert the electrical signal into sound waves and it does so according to its structural design.
With this you can know that according to the quality of loudspeakers, they have a very large range. At the same time, their cost, size, and other factors also decide their overall quality.
Most of the time you will see these loudspeakers being used inside the devices, most of the time you will see two or more loudspeaker drive units together
How to say speaker in Hindi?
Speaker is called speaker in Hindi.
How do Speakers work?
Speakers are actually transducers that convert electromagnetic waves into sound waves. Speakers receive audio input from a computer or any audio receiver. It is either in analog form or in digital form.
Analog speakers simply amplify these analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speakers first have to convert these digital inputs into analog signals, then they can produce sound waves.
The sound produced by the speakers is defined in frequency and amplitude. Where the frequency determines how high or low the pitch of the sound is.
For example, a soprano singer’s voice produces more high-frequency sound waves, while a bass guitar or kick drum produces sounds that have a lower-frequency range. That’s why we can say that the ability of a speaker system depends on its ability to generate sound frequencies, so that you can know how clear the quality of audio is.
Many speakers also include multiple speaker cones for different frequency ranges, which help to produce more accurate sounds for each range. Two-way speakers typically include a tweeter and a mid-range speaker, while three-way speakers also include a tweeter, mid-range speaker, and a subwoofer.
Amplitude or loudness depends on the change in air pressure that produces sound waves of the speaker. So when you increase the sound of your speakers, you are actually increasing the air pressure of the sound waves being produced in it.
Since the signal produced by some audio sources is not very high (such as a computer’s sound card), it is amplified with the help of speakers. For this reason, most external computer speakers are amplified, which means that the signal is amplified by using electricity in them.
Speakers that are capable of amplifying sound input are called active speakers. You can easily identify these, because if a speaker is active then it has a volume control or they can be plugged into an electrical outlet.
Whereas Speakers which do not have any internal amplification facility are called Passive Speakers. Since such speakers cannot amplify the audio signal, they require a high level of audio input, which can be produced by an audio amplifier.
Speakers typically come in pairs, which allows them to produce stereo sound. This means that the left and right speakers transmit audio in two completely separate channels. By using two speakers, the sound of music is very natural as our ears are more used to hearing the sound from both the sides at the same time.
Whereas Surround systems have four to seven speakers (plus one
subwoofer), which creates an even more realistic experience.
In most cases the speakers are categorized according to their drives as well as some of their variables which make them unique. This is very technical. So let us know about some categories of these speakers in these technical terms.
1. Dynamic Speaker
These are very common types, and they are typically passive speakers. These contain one or more woofer drivers. They are known to produce low-frequency sound and contain one or more tweeter drivers. In some cases, professional speakers also have rear drivers to amplify the sound.
2. Subwoofer Speaker
This type has larger woofer drivers, and often has a bass port in the enclosure that produces low-frequency sound. They are also used to enhance the base without compromising the sound quality with other accompanying speakers.
3. Horn Speaker
There are many similarities between these speakers and dynamic speakers, including the arrangement of drivers in a wave guide structure. Using these horn speakers allows users to take advantage of the benefits of their relatively high degree of sensitivity and transmission of sound over a large area.
4. Electrostatic Speaker
Electrostatic speakers are a great choice for those who prefer crisp and detailed sound. These diaphragm speakers feature a drive and a fine membrane that is placed over two conductive panels.
These require an outside power source and are therefore always plugged into an outside power outlet. In most cases, electrostatic speakers are used only at the highest frequencies and are not ideal for low-frequency speakers.
5. Planar-magnetic speaker
These speakers feature planar-magnetic speakers instead of diaphragms. Unlike a thin metal ribbon, and electrostatic, they do not require any external power source to operate. These come under the category of speakers which have very high utility value and can be used for a long time if proper care is taken.
What are the different types of loudspeaker and their technologies?
Many different technologies and approaches are used in Loudspeakers. Due to which today there are many different types of loudspeaker which can be used. So let’s know about some such technologies.
1. Moving Coil Speaker
This moving coil type loudspeaker is such a type which is very commonly seen. There is a cone attached to it, a coil which is placed inside a magnetic field.
This moving coil loudspeaker is such a type of loudspeaker that the first thing that comes to one’s mind when it comes to loudspeaker. It basically has a diaphragm, which is typically attached to a coil and audio is passed through them.
In this the coil is suspended within a magnetic field and which means that due to the variations of current flow which is actually caused by the electrical audio signal, it helps to move that coil and hence the cones move. As a result the loudspeaker converts the electrical audio signal into sound.
2. Horn Speaker
This horn loudspeaker type is often used for tweeters. Although it also uses the same electromagnetic effect as a moving coil loudspeaker, it has a diaphragm placed within a magnetic field that varies in line, along with the audio. This causes the diaphragm to vibrate and these vibrations are then magnified through a horn.
Horn loudspeakers are used in many areas of auto technology, and although they are used in some high quality applications, but you can see them being used in more public addresses and external things.
These horn loudspeakers have a transducer, which is often a moving coil transducer, and is connected to a horn.
You can also think of it as a matching element which is very similar to a waveguide horn antenna, and this enables them to achieve higher levels of efficiency.
You can also see this in an old gramophones, in which only one horn enables the sound to reach our ears. Without horn, the sound of gramophone is almost inaudible.
3. Electrostatic Speaker
A completely different principle is used in this electrostatic loudspeaker, which is completely different from the moving coil and horn loudspeaker.
In this sound is generated when force is exerted over a membrane which is suspended in an electrostatic field.
These were some very used technologies, except these, there are very different technologies which are used to make loudspeaker.
Different types of speakers
These traditional loudspeakers have been around since elec
tronic audio has been invented. At the same time, many changes have been seen in it in the last few years, and together it has evolved a lot according to the needs of the people. Now it is found in many shapes, sizes and variations.
So let’s know more about the different types of Speakers again. One thing you should know that each speaker has a different identity and is used for a different purpose.
What are Subwoofers Speakers
A subwoofer is a speaker that produces very low-frequency sound. They are at the fore in generating bass. Its range is between 20 to 200Hz, and this subwoofer is an omnidirectional speaker.
This means that it does not matter where you put it. Because it sends sound in all directions. Since its sound range is between 20 to 200Hz, the human ear cannot hear these soundwaves, but only feel it.
Nowadays, subwoofers have started coming in desktop speaker systems too. Due to this, the sound system has a different glory and the listener also realizes it. Now even subwoofers have started coming in powered and unpowered variants.
These passive subwoofers, unpowered subwoofers, require an amplifier or receiver to generate enough output power to push these speakers to their optimal level.
What are Studio Monitors speakers
Studio monitors are mostly used by professional audiophiles. With its excellent ability to clearly reproduce both vocals and music, studio monitors are really well optimized for casual listening and playing instruments.
There are also two types of monitors, powered and unpowered.
Powered monitors can be played by simply plugging in the wall. Since they are powered internally, they have the capability to add buzz to the speakers.
Unpowered monitors (also known as passive studio monitors). They require an external source to power them up. These are the speakers that were used in the olden days, two wires, one red and one black. Both were wrapped around a post and they were also screwed.
They don’t have buzz like powered speakers, and they don’t even require an outlet to place.
One thing to keep in mind is that whenever you buy any studio monitors, make sure that they are in pairs or not because they do not always come in pairs. Some are sold in sets, while some are also sold individually. So do check this thing before buying.
What are Loudspeakers Speakers
These loudspeakers are very common household speakers. In the olden days these were the loudspeakers that were used to get sound from television and stereo.
Now the size of these loudspeakers has reduced to a great extent and it has become very portable too. Now loudspeaker also has woofer, mid-range speaker and tweeter, which keeps us away from buying other types of speakers.
They are mainly used for stage performances, karaoke where you have to cover a large space.
Computer Speakers What are speakers
If we talk about the earlier computers, then the speakers used in them were small, which were attached to the motherboard. Later, sound cards were attached to them so that users could easily listen by plugging in their headphones.
At that time the speakers were not as powerful, but only 8-bit or 16-bit sound worked. Current generation computer speakers usually have a 2.1 (2 loudspeakers and a subwoofer) style, which is perfect for a casual listener.
Whereas for a gaming enthusiast, 5.1 or even more fully immersive 7.1 surround systems are available. These are basically plug and play systems, in which there is a USB plug from the subwoofer to the computer, and the other satellite speakers are plugged into the subwoofer for power.
Floor Standing Speakers What are speakers
All of you must have seen these Floor Standing Speakers many times around you. If you are setting up a home theater system here, or are setting up a home studio type to listen to songs, then this floor standing speaker is going to be the best choice for you. They are about 4 feet high and are easily visible from all sides of the room.
It has many different configurations and you can choose them according to the situation. Most floor standing speakers are unpowered, and require a receiver or amplifier to function.
Bookshelf Speakers What are speakers
The name itself suggests that what are these BookShelf Speakers. In a home theater setting, these medium-sized speakers play a large part in its setup.
These are directional speakers, which means they should be on your side of the ear to hear the sound properly. You can keep them on both sides of your television for the full experience. These are often 5 inches in height and usually have 2 speakers (1 mid-range and 1 tweeter) called r
This is referred to as a 2-way speaker. Like floor standing speakers, these also require an amplifier or receiver to run them.
What are In-Wall/Ceiling Speakers Speakers
Installing quality in-wall or in-ceiling speakers is not that easy. And at the same time they are a bit costly too. But if you want to stay in any room of the house and the songs follow you in every room then it becomes very important to have In-Wall Speakers there.
If you want to spend money in your home as well as listen to the best music, then In Wall Speaker is a must for you. Try to get the help of professionals to install them.
What are On-Wall Speakers Speakers
If you use on-wall speakers, there is no need for you to create large holes in ceilings and walls. You can easily mount them by making a small hole.
It has mounting brackets which makes its installation very easy. It comes in different colors and styles so that it suits the decoration of your home. On-wall speakers are also unpowered, so you need an amplifier or receiver to play them.
Satellite Speakers What are speakers
These speakers are of small size and they are wired as well as unpowered. These already have a subwoofer. This type of speaker usually has a mid-bass speaker with a tweeter. This subwoofer is a typical power source for these satellite speakers. You can put them in any place of the house.
Bluetooth Speakers What are speakers
Bluetooth Speakers do not have wires and are self powered. They are very portable so that you can play them anywhere and anytime. Their sound quality is also very good.
Surround Speakers What are speakers
Surround speakers are a very integral part of any home theater system. In this, these numbers 5.1 and 7.1 have a different meaning.
A standard system has a left, right and a center speaker (LCR). Basically these are 3 speakers which face the viewer or listener. In this, the surround also adds 2 or more channels (speakers) behind the viewer, which creates a 360 degrees sound environment. Multi-channel playback is used to send correct sound to the correct speaker, that too in the correct time.
5.1 surround consists of a center channel, left and right front channels, left and right surround channels on the side and a subwoofer. Simply put, 5 speakers and a subwoofer. This 5.1 surround system combines rear and side audio into 2 speakers. The 7.1 system is also similar to the 5.1, but separates the rear and side audio into 4 speakers.
Outdoor Speakers What are speakers
These types of speakers are designed to be weatherproof. You can also buy them according to a system or according to a single speaker as you need. Some systems have a subwoofer and multiple midrange and tweeters to cover the entire yard and patio.
The boxes of these outdoor speakers are made in such a way that they can tolerate the heat and humidity, along with the wires are also plugged inside a speaker to protect it in a weather resistant enclosure.
What are Soundbars Speakers
If you want more dynamic sound for your TV in your room without having to place any speaker then soundbars are a great option for you.
Sound bars have a very sleek design which makes it easily suited to most flat panel LCD, LED and plasma TVs and usually produces a much better r sound than the in-built speakers. Also in this you can get the experience with 5.1 and 7.1 surround systems, because there are many speakers in a soundbar which bounce the sound from the walls and send that sound to the whole room.
