What are the Sub-woofer Speakers And their uses

Subwoofer is the same kind of normal speakers but they are very different how they work. The subwoofer speakers are specially designed to produce low frequency sound. Yes the big bass sound which you hear from your speakers is caused by the subwoofers. It does not matter where you place them because it actually produce vibrations that a human can hear.
A subwoofer is specially designed to play low pitch sound frequencies. Low frequency means that they have range from 20Hz to 200Hz. The more lower frequency speakers will be able to produce the more better it will be that’s the reason for consumer items its rated under 200Hz. And for specialized live sound for example in concerts standards are that the sound of subwoofers should be under 100Hz. And for THX approved audio systems less then 80Hz is approved.
These kind of speakers are important in an audio systems these days. An audio system is not complete without subwoofers. That’s the reason they are known as the king of speakers these days.
As hip hop music is trending in this decade. Every one is going after the best bass speakers for them. And they are popular for car drivers who fit their sub woofers in car trunk to enjoy bassy sound.
You can also find such kind of speakers in cinema theatres too. They are the speakers which makes a great sound of vibration whenever some building destroys or some plan hits the ground. This all music experience is generated by these subwoofers. If subwoofers were not invented you wont be able to experience such kind of amazing sounds in your movies.
Other than that now a days they are being embedded in simple earbuds of other kind of speakers too. So you can hear bass too along other sounds too.

Technical Types of Speakers

There are different types of speaker available in the market these days. If you are the one looking for an audio solution you must educate yourself about which kind of speakers you will need for your particular needs. You should consider the power, sound quality, shape and many more features of speakers before choosing one. Not the type of speaker is important to consider while choosing, you should also research the specification of speakers before choosing. Lets let you know what kind of speakers are available in the market for you to buy and what are their uses.
Dynamic Speakers: They are normal speakers available in the market. We also call them passive speakers. They might have multiple woofer drivers along with them. They are used to produce low frequency sound.
Subwoofer: They are usually available in bigger size and used to create bass from the sound. This kind of speakers comes fitted with other normal speakers to enhance the bass of overall audio output. They are designed to create low frequency sound in order to fulfill bass needs in the market.
Horn Speakers: This kind of speakers are used to produce louder sound. They are specially designed for larger areas. They have degree of sensitivity. And they have larger amplifiers in order to produce louder sound. This kind of speakers can compromise the quality of sound output.
Electrostatic: If you are looking for crystal clear sound and don’t want to compromise on the sound quality then this type of speakers are for you. They are specially designed to produce the maximum quality of sound details. In most of cases such kind of speakers are used to produce high frequency sounds if you are looking for low frequency sound speakers we should warn you to stay away from this type of speakers.
Planar Magnetic: This kind of speakers comes with a thin metal ribbon. They are known for their long lasting. If you take good care of them they can last for years. And you wont need to replace them. This kind of speakers also provide high utility value too.

How Does Speaker Work?

Speakers come in many shapes and sizes based on their needs. For the mobile phone there are smaller micro level speaker which are designed to produce clearer sound while bigger speakers are used where you need louder size for example in your home audio system. These days there are various kinds too. Like to produce bass sound you will need woofers. But all of them are based on same physics rules. The main function of speakers is to convert electronic signals into sound waves same as we produce sound while speaking. Or any other thing making a sound. Actually it produces soundwaves which strike over our eardrums and we are able to understand those sound waves.
Every speaker contains an electromagnet which converts electrical signal to audible sound. There is a metal coil inside speakers where actually current flows and it creates current in the coil flips the poles of magnet.
And electromagnet can be found in front of permanent magnet. The permanent magnet is firmly placed in its position and it does not move while electromagnet is mobile and it vibrates on based of its electronic signals.
When current flows through it the electromagnet changes its position or in other words it starts vibration.in other words, it sometimes goes closer to the permanent magnet while sometimes it repelles from it according to electronic signals. This process happens in the matter of miliseconds.
The electronic magnet is than attached to a cone which is made with different kind of stuff according to need of the speaker. Sometimes it is made of paper and sometime it is made of plastic. But the main purpose of this cone is same. It amplifies the vibration of electromagnet which moves. So the cone does also vibrate with electronic magnet based on the electronic signal pulses. This cone then produces sound waves into air which strike towards your ears and sound is produced.
So inside a speaker there are three important things. First one is permanent magnet which actually does not move. And top of it is electromagnet which moves according to current pulses and the 3rd thing in speaker is its cone attached to electromagnet which amplifies the vibration of electromagnet to produce louder sound.
Microphone also uses the same principle but its inverse. Even you can use your earphones speakers as microphones.
These days to produce great quality sound, good speakers has different kind of cones embedded on one speaker to produce better, more quality and clearer sound.
