What Are Speaker Drivers and How It Works

What is driver in speaker is something that many are curious about because they wonder about the benefits it possesses in bringing you the best audio experience as much as possible. And if this is indeed your query, then you have definitely come to the right place! For today’s discussion, I will present to you the types of speakers and different speaker types and how they could boost the audio quality of the multimedia file you’re currently playing. I’ll also give you a recommendation of the list of devices with the best speaker drivers to help you decide which one to buy. So without further ado, let’s get right into today’s discussion. What is a Speaker Driver? The primary feature of a speaker driver that you have to bear in mind is that it is essentially a transducer. So what is a transducer anyway? In layman’s terms, it is a device that converts one type of energy into a new one that’s suitable for the device in which the energy is being emitted. In this case, the inside of speaker generates electrical pulses from a primary source and converts the data into sound waves, which are emitted through a driver. How Do Drivers in Speakers Work? Now that you know what is speaker driver, it is also important that you become informed of how these drivers work. In order to understand how a driver for speaker works, it is first necessary to understand the basics of electromagnetism. Any time an electric current flows through a conductor, it creates a magnetic field. This process can be reversed as well; when a magnetic field is applied to a conductor, it causes an electric current to flow. This principle forms the basis of speaker drivers. A typical driver consists of a coil of wire that is wrapped around a permanent magnet. When an audio signal is applied to the coil, it produces fluctuations in the magnetic field, which in turn causes the coil to vibrate. The vibrations are then transmitted to the speaker's cone, which amplifies them and emits them as sound waves. Thanks to this simple but clever design, loudspeaker drivers are able to reproduce a wide range of frequencies, from deep bass notes to high-pitched sounds.  The Most Popular Dynamic Speaker Driver Types Now that we know how the drivers work, we move on and discuss several types of dynamic speaker drivers that you have to take note of, which includes the following Subwoofer In perspective, a subwoofer dynamic speaker driver is excellent for low-frequency audio emission. They are the ones installed in larger Bluetooth speaker devices that can produce high volume and reproduce deep bass frequency sounds. Woofer A woofer dynamic driver is perfect for low-frequency audio emissions in general. A woofer is the mechanical part of a subwoofer, except that it is able to manage low-frequency sounds more effectively compared to the aforementioned. The major differences that you have to take note of between them are the speaker driver size, number of drivers, audio wave range, power output, and the cost of the device. Mid-Range As the name suggests, a mid-range dynamic speaker is designed for mid-range frequency sounds. The other term that many people use to refer to a mid-range dynamic speaker is a squawker. And this is because it can handle frequencies that range from 250 to 2000 Hz, which is excellent for casual multimedia use inside your home. Tweeter Tweeter dynamic speaker drivers are the perfect option for high-frequency audio emissions. It has a speaker driver that can easily manage a diaphragm that moves back and forth rapidly due to high-pressure audio waves. These types of dynamic speakers are suitable for music and speech presentation. Super-Tweeter Among the other four drivers listed in this article, the Super-Tweeter has the highest tolerance for very high frequencies. Apparently, it is also more costly because it’s primarily designed to produce ultra-high audio frequency. Its purpose is to recreate realistic sounds from any given environment, which is often referred to as “airiness.”  Recommendations of Speakers with Best Drivers If you are looking for the perfect bass speaker with the best drivers, whether for throwing a party or simply relaxing at home, these three top picks from soundcore are sure to impress.

A Complete Guide on How to Test Speakers

  If you're a music lover, you know how important it is to have great speakers. But how do you know if your speakers are really as good as they could be? And what should you do if your speaker can’t produce sound? Luckily, there are some ways to test them and make sure they're giving you the best sound quality possible. So if your speaker has stopped producing sounds, this article will help you out with how to test speakers by using multiple ways. Before testing the sounds, you should know how a speaker works. By doing this, you will get a better understanding of how to troubleshoot problems with a speaker Parts of a Speaker All these given components together form a speaker: Pole + Rear Plate Magnet Top Plate Voice Coil Basket Spider Cone + Surround Dust Cap How Do Speakers Work? Speakers use an electromagnet to convert the electrical signal from your amplifier into mechanical energy that moves the speaker cone, producing sound. The process begins when your amplifier sends an electrical signal to the speaker’s voice coil. The voice coil is a coil of wire that is wrapped around the magnet. Voice coils produce magnetic fields when current flows through them, which interact with the permanent magnet in speakers to cause the voice coil to move along with the cone attached. The movement of the cone creates pressure waves in the air, which your ears interpret as sound. Tools Required for Testing Speakers Without tools, it's not possible to determine the cause of the problem in any speaker. Here are some tools that you need to diagnose the issues in a speaker: AA, AAA, or a 9V Battery Multimeter Multimeter Probes Two pieces of wires AA is a heavy-duty standard-sized cell used in high-power devices like radios and big toys. On the other hand, AAA is a small-sized cell used in low-power devices like TV remotes and clocks.  How to Test Speaker Wires and Connections? Sometimes, a speaker's components are perfectly fine, however, the only problem is the wires. To test the continuity of wires, follow the steps given below: Step 1: Put the multimeter in Resistance(Ω) mode. Step 2: Connect each end of both wires to the positive and negative leads of the multimeter respectively. Step 3: If the multimeter shows any value more than 0 on the screen, the wires are good to go. However, if the value is 0, you need to change the wires. How to Test Speakers for Sound? In this section, you will learn the different ways to test the workings of speaker components. Testing Speaker with a Battery To test the speaker with a battery, you need a 9V battery. After that, follow the steps listed below: Step 1: Connect the wires to the positive and negative ends of the battery. Step 2: Now, attach the other ends of the wires to the speaker's positive and negative leads. Step 3: If you notice any pulse in the speaker, that means your speaker is perfectly fine. This technique can also be used to inspect whether the tweeters are appropriately working or not. Note: Do not keep the wires connected longer than 2 seconds, it can cause damage to the speaker. Testing Speaker with a Multimeter Grab a digital multimeter and go to the following steps to get started. Step 1: Connect both ends of the speaker to the multimeter's positive and negative leads. Step 2: If the multimeter produces a continuous tone, then there's a problem with the speaker's circuit. And the multimeter might indicate "0.L" on the digital display. Testing the Capacitor If everything is perfect but still, there's a problem that persists in the working of any speaker, you need to check if the capacitor is working or not. To test this, you need a digital multimeter that supports the capacitance measuring option. Step 1: Connect the positive lead of the multimeter with the capacitor and vice-versa for the negative. Step 2: Check if the readings of the capacitor are exactly as given on the capacitor casing. If the readings are -5 than the given, it's considered a bad capacitor. How to Test Speakers Manually? Sometimes, you want to avoid using any tools and analyze the issues by yourself. With manual diagnosing, it's not possible to get precise results, however, you will be certain about the ongoing issues with your speaker. Your speaker is probably having bigger issues if it is... Producing unpleasant and fuzzy Releasing smoke or a burning smell coming from inside. Damaged or torn with the speaker cone. Wrong with wire connections or defective wires. Losing rhythm while the music is playing. Some things like a wrecked speaker cone or flawed cables can be fixed. But issues like the speaker not working at all can't be fixed unless you test them with external tools like a battery or a multimeter. FAQs about How to Test Speakers How do I know if my speakers have good sound?There are a few ways to tell if your speakers have good sound. First, try playing a variety of music and see how well the speakers handle different genres. Second, pay attention to the soundstage, or the width and depth of the sound. Good speakers will create a wide soundstage that gives the illusion of being in the same room as the performers. Finally, listen for any distortion in the sound. Even the best speakers will produce some distortion at high volumes, but it should be minimal. If you can't hear any distortions, then your speakers are probably producing good sound. How do you test a wired speaker?A wired speaker can be tested either with a battery or a multimeter. In both cases, you have to connect the positive and negative leads of the multimeter's probe with the speaker's ends. However, out of both methods, a multimeter is an easy way to test the speaker. How can you tell positive and negative speaker wire?Usually, it can be determined via the color of the wires. The red color indicates the positive and the black one indicates the negative. However, in some cases, both wires have the same colors. Here you can notice if the terminal is big, it's positive, if small, it's negative. Conclusion Sound systems are a common and necessary part of many household and businesses. However, when they stop working properly, it can be a major inconvenience. That's why it's important to have some basic knowledge about speaker. Sound quality is an important part of any audio experience. But when sound quality is poor, it can negatively impact the listener in a number of ways. That's why it's important to choose a sound system that will deliver clear, high-quality sound. soundcore speakers are designed to provide the best possible sound quality, so you can enjoy your music without worry.

You have to admit that speakers make watching movies and listening to music better due to the acoustics.   However, before buying Hi-Fi speakers, you need to consider what the best Hi-Fi speakers for your room are and what you want to use them for. If you want to learn more about picking a Hi-Fi speaker, here’s a complete guide for you. We will also provide you with some best Hi-Fi speakers in today’s market. Read on and find them! What to Look for When Buying Hi-Fi Speakers The best portable Hi-Fi speakers are not necessarily the most expensive or popular brands. It all depends on the one that will enable you to enjoy your music better. Some of the factors you need to consider when buying one include the following: Budget Before deciding on the Hi-Fi speakers to buy, you need to determine how much you’re willing to spend. Hi-Fi speakers come in a wide range of prices, so it’s really up to you to choose one that suits your needs and preferences. Understand Your Room Acoustics It’s easier to shop for a Hi-Fi speaker if you have a solid idea of what will suit your room/ space better. Keep in mind that different speakers work best in various surroundings. So you need to consider elements such as the size of your room, the type of music you favor (does it have bass or is it more midrange), other elements of your system, and how loud you want your music to be. You should also note that the materials in the room affect the audio quality. Sound bounces on exposed surfaces and a room with large furniture and too much fabric will absorb the sound. On the other hand, an empty room will make the audio louder. Floorstanding or Bookshelf There are two main types of Hi-Fi speakers, floor-standing and bookshelf speakers. l Floorstanding Speakers Floorstanding speakers are taller and stand on the floor either using an inbuilt stand. Some modern models are at least 60cm tall and can rise to 2m. Since they typically have larger cabinets for drivers and dampening materials and produce clearer sound compared to bookshelf speakers. These speakers are more sensitive and require less power for the amplifiers to reach higher volumes. You also don’t have to get support furniture to accommodate them. However, due to their large size, they are not suitable for all spaces. They are also expensive, which locks out most prospective buyers. l Bookshelf Speakers Bookshelf speakers are designed to sit on the furniture, such as shelves, dedicated stands, or a bookshelf. They are more flexible and can be moved around the room. On the downside, they don't have the same level of audio quality as floor-standing speakers. Sound Quality Sound quality depends on personal taste. Everyone has a different opinion on good sound quality; what sounds good to one person may irritate another. To test the sound quality and find one that appeals to you, listen to several songs you like. We recommend doing this in a live setting to evaluate speakers. The music should sound as natural as possible to your ears, balance out all the tones and be enjoyable. Aesthetics Hi-Fi speakers can be beautiful and help make your room look more homely and put together. However, depending on the aesthetic of the rest of your house, a Hi-Fi speaker can be an eyesore. When deliberating on the best speaker to choose, consider getting one that fits the aesthetics of your room.

What Does Ohm Mean in Speakers？

Have you ever seen the symbol "ohm" on a speaker and wondered what it meant? The ohm is a unit of measurement for electrical resistance. Speakers have different ratings for how many ohms they can handle, so it's important to match them up correctly. In this post, we'll explain what ohms are and why they matter in speakers. Stay tuned for more speaker basics! What Does Ohm Rating Mean in Speakers? An ohm is a unit of electrical resistance. When used in speakers, it refers to a speaker's resistance to an amplifier’s power. This resistance, also known as impedance, affects a speaker’s sound quality; thus, when purchasing a speaker, the ohm rating is a crucial factor for consideration. Generally, there are 2, 4, and 8-ohm speakers. If the resistance is high, the sound will be better, crispier, and cleaner. However, the 4-ohm is the prevalent one. The more resistance or impedance, the less power you need, while the lower the ohm, the more power you need. Why Does Ohm Matter in a Speaker? In speakers, ohms are vital because they affect sound quality and loudness (loudness is measured in decibels). To get louder without producing distortion, you need to find speakers with higher impedance ratings than those with lower ratings. On the other hand, if you want to preserve clarity at high or low frequencies while getting the most volume possible out of your system, go for speakers with lower impedances. This means the lower the impedance, the more the current flows, and the greater the load, which means increased power.Similarly, the higher the impedance, the lower the current flow and load, leading to decreased power. Ultimately, the ohm rating in a speaker matters because it helps match speakers with the right amp capacity. What Are the Standard Ohm Ratings, and How Do They Affect Speakers？ The standard ohm rating for most speakers tends to fall between 4 and 8 ohms, though some higher-end speakers can have higher ratings. This rating affects speakers and determines the sound quality. For example, a 2-ohm speaker will allow more current flow and load, thus using more power than a higher-rated one. As such, you should always match your amplifier to your speaker in terms of ohm ratings. You want to ensure that your amplifier's power rating equals or exceeds that of your speakers. Keep in mind that the impedance of a speaker determines its power rating, and you need to understand this concept when choosing speakers and amplifiers for your sound system. The lower the impedance number, the more power can be outputted from an amplifier before overloading it. Therefore, low-impedance (4-8 ohms) speakers need powerful amps with high wattage levels. High-impedance (8-16 ohms) speakers are easier on their respective amps since they aren't as demanding. However, they have lower sensitivity ratings than low-impedance models (i.e., less loud). How to Choose Ohm Rating for a Speaker? Choosing the right speaker can be challenging, especially if you do not know what to look for. But to help you choose the best home rating for a speaker, here are factors to consider. The impedance This is the measure of how much your speaker resists current from your amplifier. Always check your speaker and amplifier ratings to see their compatibility and help you choose the best combination. The Power Power is measured in watts, and for speakers, it refers to the amount the speaker can handle or the amount of power that the speaker consumes from the source. This is an essential factor in the performance of a speaker, and the higher the power, the more powerful the sound produced. The amount of power that a speaker takes depends on its size and type. Speakers with higher wattage like the Motion Boom Plus, deliver better sound than those with lower wattage. So if you want to get better sound quality out of your speakers, ensure they have enough power. Sensitivity This refers to how loud a speaker is when driven by 1 watt and you are 1 meter away from it. Considering this aspect helps you determine how loud your speaker will be. Essentially, it means a speaker with higher sensitivity sounds louder than one with low sensitivity, even though it does not mean the former is better. It only means a speaker with high sensitivity can easily and comfortably reach higher volumes and remove the need for a powerful amplifier. FAQ about What Does OHM Mean in Speakers Are speaker ohms important? The resistance of speakers, otherwise known as impedance, is crucial because it helps you avoid a mismatch when connecting speakers to amplifiers or each other. What is the best ohm rating for a speaker? Speakers have an ohm rating of 2 to 8, although some may have more. Ideally, the 4-ohm is the standard and among the best rated. However, this may vary depending on individual preferences and needs. Does a speaker with a higher ohm rating have a better sound quality? Generally, the higher the ohms, the better the sound quality, but if the amplifier used can supply the needed power. Which is better, a 4-ohm or 8-ohm speaker? Your preferred speaker is determined by power because the rating will determine the speaker’s resistance level. This means a 4-ohm is better for low power, while an 8-ohm is better for high power. Conclusion Hopefully, we have answered the question: what does ohm mean in speakers. Knowing how much power your amplifier can handle and the standard ohm ratings can help you choose the right speakers for your home theater or car stereo. And as you go out shopping for your desired speaker, remember to consider all the mentioned factors, but most importantly, match the speaker and amplifier impedance.

How to Connect Speaker Wire to Receiver

Home stereo systems can be pretty challenging to connect, especially if you run the speaker wires to and from an audio stereo receiver. Not connecting the wires the right way can make the sound quality fuzzy, that is if there is any sound produced at all. In this article, we'll talk about how to connect the speaker wire to receiver. Let’s dive in! Preparation Before Connecting Before connecting a speaker wire to a receiver, you need to tell which speaker wire is positive and which is negative. It's crucial that you learn to differentiate between the positive and negative speaker wires. To do this, you need to look at the different colors on the wires. The silver wire is typically the positive wire, while copper is the negative wire. There are some cases where the speaker wire is clear; in this case, look for printed checking on the ends of the wires. You will see a positive (+) and negative (-) symbol to indicate the polarity. You can test the wire connection using AAA batteries if you need to double-check. Steps to Follow When Connecting a Speaker Wire to a Receiver Most speakers have labeled ports. So, connecting the speaker wire to the receiver is relatively easy for these gadgets. You just have to follow the steps below: For most speakers, the first step is turning off the receiver. The sound system should have two wires which you should then connect to the receiver terminals. Connect the other end of the speaker wires to the corresponding speakers. Turn it on and increase the volume to ensure the audio quality is clear. In this way, you can connect your receiver to any speaker with an impedance of 6 to 16 ohms. Just confirm the speaker's impedance before purchasing by checking the back of the information manual. How to Connect Bare Speaker Wire to Receiver   If you have a bare speaker wire, there are a few ways to connect it. The most common way is to twist the Bare speaker wire around a metal post on the back of the receiver. Another way is to use a spring-loaded connector. Simply insert the Bare speaker wire into the hole and release the spring, which will clamp down on the wire and make a connection. If you have banana plugs, you can simply insert them into the corresponding holes on the back of the receiver. Make sure that the left and right speakers are connected to the appropriate jacks on the receiver. Once all of the connections are made, turn on your receiver and enjoy your music. How to Connect 4 Conductor Speaker Wire to Receiver A speaker/ amplifier with four-conductor wires is odd but not uncommon. In most cases, the wires are bi-amped, so here’s how you can connect the speaker wire to receiver in such a case. Most receivers and amplifiers have spring clips, also called terminal posts, where the speaker wires connect. The spring clips are color-coded to make it easy to match the wires to the correct terminals. The most common colors are red and black, but some manufacturers use other colors like white, green, and blue. Strip the insulation The first thing you need to do is strip about half an inch of insulation off the end of each wire using a wire stripper. Once the insulation is removed, twist the strands of each wire together so they're nice and tight. Connect the four wires to the receiver Next, take a look at the spring clips on your receiver or amplifier. You'll notice that there are four holes in each clip - two on top and two on the bottom. The holes on the top are usually labeled "+" (positive) while the holes on the bottom are typically labeled "-" (negative). Take one of the wires and insert the bare end into one of the "+" holes on a spring clip. Make sure that you insert it all the way in so that there's a good connection. Then, do the same thing with one of the "-" wires. Repeat this process for each of the remaining three wires. Once all four wires are connected, you should be able to enjoy great sound quality from your speakers! FAQ about How to Connect Speaker Wire to Receiver What happens if you mix up the positive and negative wires? The signal cuts out when the two wires are mixed up; this is because of a phenomenon referred to as inverse polarity. One wave is positive while the other is negative, which results in silence. Knowing the correct wires to connect to each port in each terminal is therefore vital. How to connect speaker wire to av receiver The process is actually quite simple. First, locate the binding posts on your A/V receiver. These are usually color-coded, with red corresponding to the right channel and black corresponding to the left channel. Next, take your speaker wire and strip away a small section of the outer insulation. Finally, twist the exposed wire around the binding post and tighten the screw to secure it in place. How to connect in wall speaker wire to receiver? Connecting an in-wall speaker wire to a receiver is easier and similar to how you'd do it with an A/V stereo. Ensure you unplug all the wires, split the wire ends, place them onto the corresponding sockets and lock the wires onto the sockets. Conclusion Although most speakers today have Bluetooth as an option, like soundcore Flare, some may need you to connect the speaker wires to the receiver, especially if it’s a home theater. Therefore, knowing the different types of speakers and how to connect the wires may come in handy. Typically, most speakers only have two connecting wires that are clearly labeled. While those that have four conductor wires are pretty rare and a bit challenging to connect. The tips in this article should help you connect both types.

How Do Speakers Work? Speakers and Sound Production Explained

Speakers have been around for a long while now, and are found in everything from laptops, televisions, malls, restaurants, phones, and more. Despite being found in most gadgets and just about anywhere, not many have satisfied their curiosity about how speakers produce sound or how wireless speakers work. Fortunately, the science of how speakers make sound can be made easy to understand by dividing the process into digestible explanations. If you want to know how speakers work, then you found the right article. How a Speaker Works How do speakers work to create sound? To produce sound, speakers function by converting the gathered electrical energy into mechanical energy. As the air is compressed by mechanical energy, the motion is converted into sound pressure level (SPL) or sound energy. A magnetic field is generated when an electric current travels through coils of wire. In speaker systems, the electrical current travels through the system’s voice coil, which generates an electric field that is then associated with the magnetic field found within the speaker. The concept of similar charges repelling one another and opposite charges attracting can be found in the production of sound within audio systems. When the audio signal travels through the voice coil, musical waveforms begin to rise and fall, which is essentially the repelling and attraction of the voice coil with the permanent magnet. This produces the back and forth motion of the voice coil, which is what gives it that cone-like structure. From the alternating motion, pressure waves are in the air, which is what we hear as sound.   Step-by-step Process of How do Speakers Produce Sound Step 1. The Generation of Initial Musical Waveform After powering the sound system from zero, the output voltage serves as a representation of the initial musical waveform, which starts by beginning to rise. The generated electrical current then begins passing through the sound system’s voice coil by bouncing alternately between the negative and positive sides. Step 2. A Magnetic Field is Generated around the Voice Coil As a result, a magnetic field is produced surrounding the voice coil, which has a similar polarity to the magnet found in the speaker frame. The identical magnetic fields repel one another, while the opposites are drawn to each other. Step 3. Air Pressure is Generated The diaphragm or cone then proceeds by starting to move forward, which produces air pressure. This air pressure produces the audio that people perceive and hear as sound. Step 4. The Increase in Current Leads to An Increase in the Magnetic Field Strength of the Voice Coil The rising of the electrical signal voltage towards the upper sine wave of the musical signal translates to an increase in electrical current, which also allows an increase in the magnetic field strength of the voice coil. Step 5. Further Outward Extension of the Cone The overall increase allows the cone to project out further. Step 6. Current Drops to Return the Diaphragm to the Initial Closed Position After the signal flows by the highest possible output, it starts to decline. Accordingly, the electrical current also begins to decline, bringing the diaphragm closer to its initial off position at zero voltage. Step 7. The Signal Returns to the Zero Position and the Diaphragm Returns to the Initial Position The signal eventually reaches its zero position or “zero voltage crossover threshold”, and the diaphragm is returned to where it began. Step 8. The Signal Starts Its Reverse Process The signal then starts the process in reverse, while also changing into a negative voltage. During this change, electrical current travels from the negative area of the voice coil to the positive area, which produces a magnetic field in reversed polarity. Step 9. The Action of the Magnetic Field Causes the Diaphragm to Move Since the magnetic field of the voice coil is the opposite of the magnet found in the speaker, an attraction begins and the diaphragm starts to travel from the front side to the back. This is the opposite of the original path of back to front. Step 10. The Diaphragm Travels in Reverse As the electrical signal proceeds its path, the diaphragm also travels in reverse. This produces the sound waves’ other half, which was made through the air motion. Step 11. Stereo Output or System Amplifier Returns to Initial Point. New Cycle Starts The stereo output or system amp will then return to its initial point at zero, where the following signal starts to form as another electrical signal voltage begins to rise. This will start the cycle again, and keep repeating when the audio system is in play.   In essence, speakers are powered by electrical signals, which transform into mechanical energy that produce air motion, creating sound. What Separates a Good Speaker from a Bad One? The ideal sound test for speakers is done by comparing the similarities of the waveform or pressure wave in the air to the electronic wave or audio recording that passed through the system amplifier. The frequencies are reproduced to be heard by a listener, who determines whether the frequency sounds are accurate and without any change. If the frequency accuracy is high and does not alter any detail, then the speaker is likely to be an excellent one. Otherwise, low-frequency accuracy with some noticeable change in information can indicate lesser audio quality. For a great option of speakers,  soundcore 3 offers exceptional value for money. Testing speakers involve a handful of factors that determine the audio accuracy and overall listening experience. These speaker factors include details such as the audio dispersion, distortion, and frequency response. Among the determining factors, the frequency response is the most important and has the most significant effect on the audio.  Importance of Frequency Response In essence, the frequency response is the speaker system’s loudness across varying frequency levels. This means that the frequency can have varying output quality with each level of frequency. In testing frequency, varying frequency levels are sent from the system’s lows to mids, then all the way up to the highs and treble to determine whether the audio remains the same across each level. Ideally, the best frequency for a speaker system is flat, which means that the frequency does well in retaining the same level from the highs, to the mids and lows. Frequency response generally aims to ensure that audio is heard as it is intended to sound to other people. The frequency response essentially helps determine audio accuracy across different frequency levels. The best audio and listening experiences tend to produce sound with a flat frequency response, which is likely to sound crisp and ideal on just about any playback system. Frequently Asked Questions about How do Speakers Work How Fast Does a Speaker Vibrate? The vibration frequency or speed of a speaker depends on the audio system’s design, specifically the audio signal frequencies found in the audio drivers. The sound range generally varies from 20Hz to 20 kHz, with many speakers able to vibrate within an audible range with lower bandwidth. How Does Sound Travel Through a Speaker?  The speaker generates sound as a result of vibration or motion in the air. Aside from air, sound can even pass through solids and liquids, with speakers that we listen to having transmitted through the air as the medium. Every time an object vibrates, the air particles surrounding it moves.    Why Do Speakers Have Magnets?  All speakers or amplifiers have an electrical current that they utilize for producing sound. When electrical current transforms, it forms a magnetic field. To make the speakers’ cone vibrate, built-in magnets are included to produce a magnetic field in opposition to the electrical current’s magnetic field. Since the two magnetic fields are opposing and repel one another, vibrations are created, which produce the sound we hear. Conclusion The curiosity of knowing how speakers work does not have to be suppressed by the intimidating science of speakers and can be made easy to understand through a concise breakdown of the process of speakers and how they work. In the end, discovering something new about something so common in everyday life like the speaker, is well worth the effort.
