Parts of a Microphone. Microphones are essential tools in audio recording and broadcasting. Understanding how microphones work will help you choose the right one.
This guide will explain the dynamic mic and its seven essential parts. It is versatile and reliable.
Introduction to Microphones
What is a microphone?
A microphone converts audio waves into an electrical signal. A microphone is a transducer device that records sound, makes it louder, or sends it out.
Different types of microphones
There are different microphone types in the market. Each has unique characteristics and uses.
Some main types include dynamic microphones, condenser mics, and ribbon microphones.
Understanding the Dynamic Microphone
What is a dynamic microphone?
A dynamic microphone, or a “mic,” is a standard recording and live sound microphone. It is durable, versatile, and can handle high sound pressure levels well.
How does a dynamic microphone work?
It changes the sound to an electrical signal with seven essential microphone parts. These include the coil, capsule, diaphragm, magnet, magnetic field, XLR connector, and housing.
Coil
The coil is a crucial part of the mic. It is a small, lightweight wire wound around a magnetic core. The mic’s ring shudders when audio waves enter it.
This vibration creates an electric current that mirrors the original acoustic waves. When it moves in the electromagnetic field, it creates a voltage.
This voltage gets amplified and turned into an audio signal. You can record or send the audio signal.
The ring acts as a transducer, converting acoustic energy into electrical energy. The microphone adjusts to sound changes and records different frequencies.
The core’s electromagnetic field helps amplify the electrical current generated.
Winning a thin wire, such as copper, creates a compact and lightweight structure.
The number of turns in the coil can vary, with more turns generally resulting in a higher output voltage.
The ring is usually connected to a thin, flexible membrane. This membrane moves back and forth because of audio waves.
When the diaphragm moves, the ring moves in an electromagnetic field. It generates an electrical current.
People know the ring for its strength and ability to handle loud sounds. The mic type is not affected by moisture or temperature changes.
You can use it in different environments. Also, dynamic mics are often more affordable than different microphones.
The ring is crucial in converting acoustic waves into electrical currents. When the object shudders, it creates a voltage in an electromagnetic field.
This voltage reflects the original sound and helps capture audio.
Capsule
The capsule houses the coil and diaphragm. The cover protects the microphone and improves sound capture.
The capsule is a crucial microphone component as it houses the ring and diaphragm. The coil changes sound into electricity, and the diaphragm catches the sound as it moves.
It serves many purposes. It protects from dust, moisture, and physical damage by acting as a cover. This protection ensures the longevity and durability of the modern microphone.
The capsule design enhances the microphone’s ability to capture sound. The shape and size of the microphone can change how it picks up sound.
We can measure how sound reacts to different frequencies. Sound can adjust its sensitivity.
Manufacturers create it with specific traits. And adapt the microphone’s performance for different purposes.
The manufacturing process determines how well the capsule resists noise and proximity effects. If you move or touch the microphone, it makes a noise that you don’t want.
The design tries to reduce vibrations and keep the sound pure.
The bass response improves when a sound source gets closer to the microphone. Different designs and technologies reduce this effect.
Regardless of the sound source’s distance, they balance the frequency response.
The microphone capsule is like a cover that captures sound. The microphone’s shape affects how it hears pitches.
It also captures sounds from different directions. It also determines its sensitivity. It also reduces handling noise and minimizes the proximity effect, ensuring high-quality sound.
Diaphragm
It is a thin membrane that moves in response to audio waves. As the coil shudders, it causes it to oscillate as well.
Its movement produces audio waves amplified and projected through the speaker. It is the main component that converts electrical currents into audible sounds.
The ring reacts to vibrations. It’s made of light materials, like paper, plastic, or metal. The speaker’s sound quality and clarity depend on how well it oscillates.
Magnet
The magnet creates a static electromagnetic field within the microphone. It forces the ring to oscillate when acoustic waves pass through.
When audio waves hit a microphone’s diaphragm, it moves back and forth. This movement causes the ring to move. The solenoid situates the ring within an electromagnetic field.
As the coil moves, it cuts through the magnetic lines of force in the field, inducing a voltage in the ring.
The voltage depends on how the ring moves and the acoustic waves that hit the diaphragm.
The induced voltage goes to an amplifier. The amplifier makes the signal stronger and changes it to an electrical current.
You can record or send the current to other devices for processing and playback.
In short, the microphone’s solenoid makes an electromagnetic field. This field reacts with the ring.
This makes the ring shudder and creates an electric current when sound waves hit it.
Magnetic field
The magnetism from the solenoid makes the coil in the microphone move back and forth.
The ring moves back and forth. This makes an electrical current because of the electromagnetic field. The current is like a picture of the sound waves in the microphone.
The coil creates different electric currents. These currents go through the microphone circuitry. It can make an electrical current louder and send it out.
The microphone converts sound waves into electrical signals. You can use these signals for recording or broadcasting.
XLR connector
The XLR connector is three-pronged. It connects the microphone to audio equipment like mixers.
It also connects to preamps or recording interfaces. It ensures a secure and balanced connection for the audio signal.
The coil in the microphone moves and changes the electromagnetic field in the ring. The ring causes an electric current to flow.
The current represents the sound waves the microphone captures.
When sound reaches the microphone, it moves. This movement causes the ring to shake in the electromagnetic field.
The ring moves and creates a changing electromagnetic field in the coil. This causes an electric current to flow.
This induced electric current represents the audio signal. The microphone circuitry amplifies and processes the sound.
Then, a cable sends it to a recording device or sound system for playback.
Housing
A dynamic has a housing that protects its internal components. It also reduces noise and vibrations that could affect the microphone’s performance.
The housing keeps the inside safe from damage when dropped or hit.
The cover protects the fragile parts, like the diaphragm and coil. Helping it last longer and avoid expensive repairs or replacements.
We build strong and durable housing using solid metal or plastic materials. It can handle live performances and studio recordings.
You can use versatile, dynamic microphones on stages or at outdoor events. They can also take rough handling.
The housing helps reduce noise and vibrations, which could affect the microphone’s performance.
Wind gusts, footsteps, and equipment vibrations do not damage the microphone’s diaphragm. This prevents distortion of the audio it picks up.
The housing isolates the internal components for better sound reproduction. It makes the microphone pick up your desired sound and lessens background noise.
This makes recordings better or vocals clearer.
The housing of a dynamic microphone is essential for its performance and durability. It protects the internal parts, reduces noise, and improves sound.
Exploring Other Types of Microphones
While dynamic mics are popular and used, other types are worth exploring.
Condenser microphone
Condenser or capacitor microphones are susceptible and deliver exceptional sound quality. A condenser mic uses a charged diaphragm and requires phantom power.
Ribbon microphone
Ribbon microphones are delicate yet regarded for their smooth and warm sound reproduction. They use a thin strip of metal made of aluminum to capture sound.
