MEMS Microphones
MEMS (Micro-Electro-Mechanical Systems) microphones are a type of condenser microphone that uses a small diaphragm and a backplate to detect sound waves. They’re commonly used in true wireless earbuds and are known for their small size and high sound quality.
Where is the Mic on Earphones?
The location of the microphone on earphones can vary depending on the type of earphone and the design. Here are some common locations where you might find the microphone on earphones:
Boom Arm Microphones
Some earphones, especially gaming headsets, have a boom arm microphone that’s located on a flexible arm. This type of microphone is usually a dynamic microphone and is designed to be positioned close to the user’s mouth.
Microphone Grille
Some earphones have a visible microphone grille that’s usually located on the earcup or the headband. This type of microphone is often a dynamic microphone and is designed to pick up sound waves from the user’s voice.
Inline Microphones
Some earphones, especially wired earbuds, have an inline microphone that’s located on the cable. This type of microphone is usually a condenser microphone and is designed to pick up sound waves from the user’s voice.
True Wireless Earbuds
True wireless earbuds often have a microphone located on the earbud itself. This type of microphone is usually a MEMS microphone and is designed to pick up sound waves from the user’s voice.
How Do Earphone Microphones Work?
Earphone microphones work by converting sound waves into electrical signals that can be transmitted to a device. Here’s a simplified explanation of how earphone microphones work:
Sound Waves
When you speak, your voice creates sound waves that travel through the air. These sound waves are made up of pressure waves that oscillate at different frequencies.
Diaphragm
The microphone diaphragm is a thin membrane that’s suspended in front of a coil of wire. When sound waves hit the diaphragm, they cause it to vibrate.
Coil
The coil of wire is suspended in a magnetic field. When the diaphragm vibrates, it causes the coil to move back and forth within the magnetic field.
Electrical Signal
As the coil moves back and forth, it generates a small electrical signal. This signal is then transmitted to a device, such as a phone or computer, where it’s decoded and played back as sound.
Factors Affecting Earphone Microphone Quality
There are several factors that can affect the quality of an earphone microphone. Here are some of the most common factors:
Noise Cancellation
Noise cancellation is a technology that’s designed to reduce background noise and improve microphone quality. Some earphones have active noise cancellation, which uses one or more microphones to detect and cancel out background noise.
Wind Noise
Wind noise can be a major problem for earphone microphones, especially in outdoor environments. Some earphones have wind noise reduction features, such as foam windscreens or mesh grilles, that can help reduce wind noise.
Proximity Effect
The proximity effect is a phenomenon that occurs when a microphone is placed too close to the sound source. This can cause the microphone to pick up more bass frequencies than treble frequencies, resulting in a boomy or muddy sound.
Conclusion
In conclusion, the microphone on earphones is a crucial component that’s designed to pick up sound waves from the user’s voice. There are several types of microphones used in earphones, including dynamic microphones, condenser microphones, and MEMS microphones. The location of the microphone can vary depending on the type of earphone and the design. By understanding how earphone microphones work and the factors that affect their quality, you can make informed decisions when choosing the right earphones for your needs.
