Herbert Huffner

As You Know, There Are Different Types Of Speakers, Such As Tweeters, Subwoofers, And Midrange Speakers, Which Are Different From Each Other.

In this article, while examining the types of speakers, we explain their use.

The importance of the speaker and its types

For audiophiles, not all speakers are created equal. In this, terms such as Tweeter, woofer, and midrange are defined, which refer to their working class and frequency spectrum. Each type of speaker is designed for a specific use and has different characteristics.

What is a midrange speaker?

Various speakers from different brands are available in the market, with varying abilities in playing music and reproducing low-pitched sounds. But what is the difference between the different types of speakers, and why do cheap speakers usually not have good sound quality?

If you want to buy a high-quality audio system or Hi-FiIf you have visited the market, you have probably come across different speakers and types of audio systems. Among them, terms like Tweeter, Wooferand Mid-RangeThey are used abundantly.

But what do Tweeter, woofer, and midrange mean, and what speakers do they refer to? How important are these terms in choosing the right speakers for listening to music, watching movies, or playing games?

In this article, while getting acquainted with the sound spectrum that the human ear can recognize, we will examine the types of speakers used in audio systems and the importance of paying attention to the type of speaker in buying a suitable audio system.

How does the human ear hear sounds?

Before examining the types of speakers and how audio systems work, getting familiar with how to create sound and hearing seems necessary. In simple terms, sound comprises a collection of vibrations that reach your ears.

The sound of musical instruments such as drums creates physical vibrations by striking the drum shell. When we hit the drum, the vibration of the drum shell creates a pressure wave in the air molecules near it, resulting in sound waves.

When sound vibrations reach the human ear, they are finally converted into electrical signals and reach the brain. The human ear can only hear sounds in the frequency range of 20 Hz to 20,000 Hz; the human ear cannot hear sounds outside this range. Unfortunately, as we age, our hearing range also decreases.

What is a speaker, and how does it work?

After familiarizing myself with the basic concepts of creating, transmitting, and listening to sound, It’s time to check how the speaker works, which follows the principles of magnetic fields to create different sounds. The speaker uses three main components to create sound waves called Driverare, also known.

The main components of a speaker are:

Diaphragm: The speaker uses a diaphragm to create sound vibrations. The diaphragm is a thin plate made of paper, plastic, or metal called Voice CoilConnects.

Voice Coil:

The voice coil is a copper coil that acts like a magnet when an electric current passes through it and creates a magnetic field. Current through Voice CoilIt changes based on audio signals. Since the voice coil is connected to the diaphragm, the changes in the current that are proportional to the sound waves cause the vibration of this part of the speaker. In a way, electrical energy is converted into mechanical energy to transmit sound waves through air molecules.

Permanent Magnet:

Diaphragm and Voice CoilThey are placed between one or more permanent magnets. The force of repulsion or attraction between the coil and the magnet vibrates the speaker’s diaphragm, creating sound waves.

Speakers are connected to digital equipment such as a computer, smartphone, or analog-to-digital converter ( DAC) .). These devices send audio signals through electric current to the speaker, which is finally sent to the Voice Coilreaches and causes the diaphragm to vibrate and produce sound. Audio signals are a combination of different sine waves.

When the sound waves to the Voice Coilarrive, a variable current is created in the coil. The alternating electric current turns the coil into a magnet whose poles change continuously.

Since the diaphragm and voice coil are surrounded by the magnetic field of a permanent magnet, the force of attraction or repulsion based on the polarity of the Voice coil is applied to it at any moment and reaches the diaphragm. This mechanism enables the speaker to reproduce sound waves or music rapidly. However, a diaphragm alone cannot create all audio frequencies, so a set of different types of speakers are used in a quality audio system.

Getting to know the types of Tweeter speakers, Wooferand Mid-Range

Music can consist of various sound waves with a frequency of 20 to 20,000 Hz; naturally, a diaphragm alone cannot reproduce such a wide range of frequencies. Therefore, manufacturers of advanced speakers usually use diaphragms of different sizes to create a wide range of audio frequencies.

The difference in the size of the diaphragm causes different types of speakers to reproduce specific frequencies more accurately, depending on the purpose for which they are designed. Other speakers are divided into three categories based on the difference in the size of the diaphragm and the reproduction of different sound spectrums, including the Tweeter., Woofer and mid-range are classified.

What is a Twitter speaker?

Due to working in high frequencies and the sound in this section being more similar to the sound of birds, these Tweeter speakers are called. The correct pronunciation of this phrase is Twitter, but among marketers and people active in sound, Twitter is used more.

Although the frequency range of all tweeter speakers is different, most Tweeters are used to create sound waves in the 2,000 to 20,000 Hz frequency range.

Since the new Tweeter speaker should produce sound waves with a high-frequency spectrum, a smaller diaphragm makes this speaker. With a switch with a smaller diaphragm size, Tweeterenables it to reproduce high-pitched sounds with high precision with optimal electrical energy consumption.

Super-Tweeter speakers are also used when more accurate high-frequency sound production is considered. Are used that are more capable of producing exact sounds in the following frequencies.

Mid-range speaker)

The name Mid-RangeIt shows the Madiranj speaker is designed to reproduce sounds in the middle range of the audio spectrum that humans can recognize. Usually, these speakers produce sound waves in the 500 to 4,000 Hz frequency range.

Since a large part of the sound waves in a piece of music are in the middle-frequency range that the human ear can recognize, it is more important to choose a speaker that has a good performance in reproducing this frequency spectrum—diaphragm size of Mid-Range speakers in the middle of Tweeter and WooferPlaced.

In some cases, the word Squawker or SquawkerIt is used for this class of speakers, which has the same concept of midrange and the frequency range between 250 to 2000 Hz.

Woofer speaker)

WooferIt is responsible for reproducing the lowest sound spectrum and creating bass or bass sound in an audio system. Regarding frequency spectrum, most woofers work in the 20 to 2 thousand Hz range.

For this purpose, Wooferare made larger diaphragms to vibrate more molecules in the air. Remember that WooferIt does not perform well in reproducing high-frequency spectrum and sharp sounds.

Woofer location and installation have a direct effect on its performance. Therefore, they often install woofers in a chamber to produce a better bass sound.

What is the difference between 2.0, 2.1, 5.1 and 7.1 speakers?

You may have seen these modifications when buying or reviewing speakers that compare speakers with some numbers. These numbers are the number of pieces or real or virtual channels that are reached by using different speakers with different quality and frequency coverage.

The main differences between 2.0, 2.1, 5.1, and 7.1 speakers are the number of channels and the presence or absence of a subwoofer. A subwoofer is a speaker that plays only low frequencies and enhances the bass sound. The number of channels indicates the number of side speakers that play sound from different angles.

 In summary:

How does the audio signal get from the computer to the audio system?

When playing music, the computer sends the corresponding signals to the speaker through wires. Then, audio signals using a section called Crossover Network are distributed. Crossover NetworkIt is an electronic circuit that separates audio frequencies.

A crossover circuit

Suppose you have purchased a speaker that works with Tweeter speakers. In that case, Wooferand Mid-RangeIt is equipped with the signal from the computer by the Crossover Network, a selfie, and a capacitor filter network divided into three parts. Low-frequency audio signals, signals in the middle range, and high-frequency audio signals are sent to the Woofer speakers, respectively. Mid-Rangeand Tweeterare sent

All audio signals are sent simultaneously to the speakers in an audio system so that you can enjoy listening to high-quality and detailed music.

Summary and answers to frequently asked questions

Music consists of a combination of different frequency ranges, so using one speaker to reproduce all the sound ranges will not produce a favorable result.

In this article, we examined the types of speakers after learning how to create sound and the general principles of a speaker’s operation in simple language and away from technical complications. Knowing the contents of this article will help you make the best choice when buying a speaker or an audio system.

According to the points we discussed in this article about the types of speakers, getting woofer speakers for playing music is recommended. Mid-Range and Tweeterbe equipped.

How many types of speakers are there?

In short, it can be said that there are three common types of speakers.

What are the different names for speakers?

Common types of speakers include tweeters, tweeters, and woofers. Another name for a woofer is the subwoofer.

What is a class A speaker?

The simplest type of amplifier used in standard audio systems is Class A. Class A amplifiers have the highest accuracy in sound reproduction but the lowest energy efficiency.

How to choose the right speaker for your computer or laptop?

To choose the right speaker, you should consider factors such as the type of use, the desired space, sound quality, number of channels, output power, signal-to-noise ratio, impedance, sensitivity, response frequency, and portability. You should also compare the prices of different speakers according to your budget and choose the best option.

What is the difference between a speaker and a band?

The speaker is an electromagnetic transducer that converts electromagnetic sound into compressed air sound. A band is an arrangement of several speakers in a wooden or plastic box that uses a frequency divider circuit (crossover) to divide the incoming sound into different parts and direct each part to a suitable speaker.

What connections can be used to connect the speaker and the computer?

There are three general ways to connect a speaker to a computer:

What are the advantages and disadvantages of wired and wireless speakers?

In principle, the advantages and disadvantages of wireless and wired speakers can be compared as follows:

What are the main differences between 2.0, 2.1, 5.1 and 7.1 speakers?

The main differences between 2.0, 2.1, 5.1, and 7.1 speakers are the number of channels and the presence or absence of a subwoofer. A subwoofer is a speaker that plays only low frequencies and enhances the bass sound. The number of channels indicates the number of side speakers that play sound from different angles.
