In the previous article “What is the Difference Between a Microphone and a Speaker?” I discussed the importance of the microphone stand as a sound source for the recordings.
While that information is helpful, many sound engineers don’t realize there is another important accessory to recorders-the microphone.
What is the difference between speakers and microphones?
The microphone stand is often overlooked, but it can make a big difference in the quality of the final product.
Microphones need to be placed in a certain way in order to catch the sound wave.
The distance the microphone has from the stand needs to be measured.
If the microphone is too close, the signal will not be captured.
Likewise, if the stand is too far away, the sound will escape.
This makes choosing the right distance between the two important to the sound engineers.
In addition, if you are using multiple mics then you will need stands that will provide each mike with approximately the same distance from the mic.
Use a balanced set up
This is called a balanced set up, and it is often the standard for a studio or home system.
If you are placing the mikes closer together or closer to one another, then the distance between the mikes should be increased to allow for more freedom of movement for the audio engineer.
If you are not using a balanced set up, then you will want to keep the distances close to the same in order to maximize the bandwidth of the audio.
With that being said, let’s look at the other components of the microphone stand.
Use the right distance
The distance from the mic to the speaker should be in the same direction.
This means that the distance from the wall behind the person talking should be in the same direction as well.
Remember, that a directional microphone can be extremely useful for a studio or other controlled environment.
However, if you are performing live, then you will want to keep the distance as far away from the audience as possible.
You might also want to consider the ground bounce, which is a distance that the actual speaker will stand when there is no cushion beneath them to absorb the shock.
A good rule of thumb is that the floor should be about two feet away from the speaker when they are standing.
For acoustics, this is usually the distance between a speaker and a microphone.
It is the distance between the floor and the speaker when the sound is bounced back from the floor.
A main difference between the two is the diaphragm
If you are looking for the difference between a speaker and a microphone then you need to look at the diaphragm.
It should be made from rubber or metal because it absorbs more shock than the other components.
The diaphragm also controls the distance that the sound waves travels.
Speakers with open diaphragms will produce sounds above the heads of the listeners.
This will result in a lack of sound projection and a lack of imaging.
The distance between a microphone and speakers can also make the difference between a speaker and a microphone.
Microphones will typically be on stands while speakers will be clamped to the floor.
The main advantage of speakers
The main advantage of standing speakers over standing microphones is that the mike can pick up the best of the sound.
Standing ones are also usually much larger than the ones found on stands.
When you are talking to others, you need to make sure that the mic that you are using is the right one.
Make sure you do not choose one that produces a lot of static or echo.
You can test the microphone by connecting the microphone to your computer.
If the sound is too distorted then it probably is a microphone problem.
Can you use a microphone without a speaker?
If you ask yourself, “Can you use a microphone without a speaker?” the first thing that might come to mind is a computer or microphone.
Although you can purchase a device called a computer microphone that is designed specifically for wireless use, most people do not want to carry around a bulky device and there is also the sound quality issue to consider.
There are many different types of wireless microphones on the market today from simple wired mikes to wireless headset microphones.
If you are going wireless, make sure that the device that you choose is compatible with your computer’s operating system.
Wireless microphones are usually only capable of operating within their own frequency range.
Adjusting the frequency levels
Most computers will allow you to adjust the frequency level for the wireless microphone in order to maintain clarity when you speak or talk over long distances.
Some wireless microphones will automatically switch over to the appropriate frequency once the receiving device detects that you have changed the setting.
These devices are perfect for people that need to talk over long distances without worry of missing a word.
If you want to use a wireless microphone without a speaker, then there are other options available.
You can obtain a simple USB microphone that acts as a speaker and the sound card of your computer.
However, these mics are often bulky and not as flexible as one that uses speakers.
What about Bluetooth microphones?
A Bluetooth microphone is similar to its computer counterpart and is great if you want to use the sound quality of the device without worrying about wires or cords.
Bluetooth mics work on the wireless network of your computer.
This means that instead of wires connecting you to your device, it connects through the Bluetooth signal.
These types of devices can be found in stores and can also be adjusted to receive sound in stereo or mono.
The cost of buying a Bluetooth wireless microphone will vary by size and brand.
You can also find wireless microphones that are smaller than the size of a golf club.
The smallest wireless microphone that you can buy is one that can be used to play voice messages on your telephone.
They are also useful in the television or video industry as they can be used to record audio programs and transmit them to a recording studio.
Can mics be used autonomously?
Microphones without a speaker can also be transmitted through USB or PC direct connection.
This means that the device can be used with computers or laptops.
These devices are normally smaller and you can attach it to your computer monitor with the help of a USB cable.
It can also be connected to personal digital assistants (PDAs) or cell phones.
If you are looking to purchase a microphone with no screen, then this type of device is also known as a hands-free microphone.
The main features of the microphone
Some newer versions of these devices are completely touch-sensitive.
They have a button on the side which operates the device and when the button is pressed, it automatically recognizes the user’s commands.
They are very useful for people who are using a computer but want to control the sound volume from wherever they are.
There are many types of multimedia devices that have wireless capabilities.
There are various other features as well.
When looking for a microphone for your device, make sure it has the following features: wireless device, if your device supports wireless device then it should also have a range that depends on the distance between the user and the speaker, it should also have a volume control, and it should have auto mute, volume indication, speaker alerts and so on.
This information should be available in the manual or the owner’s manual.
How does an audio speaker work?
To answer the question, “How does an audio speaker work,” we need to take a look at its mechanism.
As mentioned above, the principle is air compression followed by sound vibrations in the speaker cones.
The vibrations result in signals that are then sent to the speaker’s diaphragm.
The diaphragm acts like a spring that compresses and then expands the air inside it, creating the desired sound waves.
There are four components that make up a speaker
The diaphragm consists of a cone, which is covered by a baffle that reduces or eliminates sounds from the direction of the cone falls.
This is done by reducing the cone’s baffle, which in turn makes the cone more linear; this results in better bass response and greater power handling.
The sound waves
The woofer is mounted in the rear of the speaker cone.
A tweeter is added to the rear of the cone for the sounds to be amplified.
At the end of the cone is the basket which contains the actual speaker.
The woofer is contained within the basket.
Air is compressed between the two walls of the basket, creating the speaker’s vibration.
Sound waves are then sent to the tweeter, which is placed in front of the speaker.
Sound waves from the tweeter are then amplified by the air amplifier and sent out as sound through the speaker.
Understanding the process
Although the process is fairly complicated, a basic understanding can be attained by examining the speaker’s mechanics.
The speaker’s diaphragm is at the center of the speaker, between the speaker’s woofer and tweeter.
Because of the woofer’s tendency to move about when the speaker is being operated, the diaphragm has to remain perfectly still in order to avoid the movement of the speaker.
Moving the diaphragm affects how the sound is distributed from the speaker to the listener.
If the diaphragm is not able to remain perfectly still, sound waves will resonate with the vibrations and travel through the speaker’s cone.
The vibrations will then be transmitted to the rest of the speaker’s cone and to its woofer.
The vibrations combine with the air’s density to create a vibration that sends the sound waves into the speaker’s speaker box.
The speaker creates sound when it vibrates
The air amplifier on the other hand uses a motor to increase the air pressure inside the speaker’s basket.
Increasing the air pressure increases the vibrations in the speaker’s basket, sending the vibrations to the speaker’s tweeter.
When the tweeter is struck by the sound waves, it amplifies the vibrations and causes them to reach the speaker’s enclosure.
Finally, the vibrations reach the rest of the speaker’s cone and creates a signal which is then amplified by the speaker’s air amplifier.
In order to do this, the diaphragm must remain perfectly still, as it is the key to achieving a proper stereo effect.
The diaphragm must also be aligned properly; some manufacturers use a mouse to help align the diaphragm for better sound quality.
The positioning of the speaker
The proper positioning of the speaker will ensure that the sound waves reach all parts of the audio speaker.
This is why some audio speakers have “hydro-stability” systems that use water to keep the diaphragm in place, ensuring that the speaker is perfectly still while the music is played.
It should be noted that the sound wave itself is not made by the diaphragm.
Sound waves are produced by the speaker’s cone, woofer and air amplifier.
Thus, in order to answer the question “How does an audio speaker work?” it is important to know how these different components work together.
The cone is the part of the speaker that receives the sound waves, and the woofer is the part that produce these sound waves.
Lastly, the air amplifier is used to power up all of the components of the speaker.
