Air Conduction Headphones Working Principle


Air conduction headphones are one of the popular types of headphones. They are used for a variety of purposes, including listening to music, watching movies, and making phone calls. These headphones work by converting electrical signals from audio devices into sound waves that are transmitted through the air and into the ear canal. In this article, we will introduce the working principle of air conduction headphones in detail.


Components of Air Conduction Headphones

The basic components of air conduction headphones include the driver, the diaphragm, and the magnet. The driver is a small speaker that is responsible for producing sound. It is usually made of a cone-shaped diaphragm that is attached to a voice coil. When the voice coil receives electrical signals, it moves back and forth, causing the diaphragm to vibrate and produce sound waves.


The diaphragm is a thin, flexible membrane that vibrates in response to electrical signals from the audio device. The size, shape, and material of the diaphragm can affect the quality of the sound produced by the headphones. Typically, diaphragms are made of materials such as paper, plastic, or metal.


The magnet is responsible for creating a magnetic field that interacts with the electrical signals to move the diaphragm and produce sound waves. The strength of the magnetic field can affect the sensitivity and efficiency of the headphones.

Working Principle of Air Conduction Headphones


When an electrical signal is sent from an audio device to the headphones, it is received by the driver. The driver then converts the electrical signal into a series of vibrations that are transmitted to the diaphragm. The diaphragm vibrates in response to the electrical signals, causing the air around it to vibrate as well. These vibrations create sound waves that are then transmitted through the air and into the ear canal.




The sound waves generated by the diaphragm are directed toward the ear canal by the design of the headphones. The air conduction headphones are designed to position the driver in such a way that the sound waves are directed towards the ear canal, allowing them to be heard by the listener.


The quality of the sound produced by air conduction headphones depends on several factors. The size and design of the driver can affect the frequency response, which is the range of frequencies that the headphones can reproduce. Headphones with larger drivers can generally produce lower frequency sounds, while headphones with smaller drivers are better at reproducing higher frequency sounds.


The material used for the diaphragm can also affect the quality of the sound produced. Diaphragms made of different materials have different resonant frequencies, which can affect the clarity and accuracy of the sound produced. For example, diaphragms made of paper are often used for producing warm, natural-sounding audio, while diaphragms made of metal can produce crisp, bright audio.


The strength of the magnetic field created by the magnet can also affect the quality of the sound produced. A stronger magnetic field can make the headphones more sensitive and efficient, allowing them to produce louder and clearer sounds. However, a stronger magnetic field can also increase distortion and affect the accuracy of the sound produced.

Advantages of Air Conduction Headphones

Air conduction headphones have several advantages over other types of headphones. They are lightweight, portable, and easy to use. The open-ear design improves safety during use. They are also relatively inexpensive compared to other types of headphones. This makes them a popular choice for people who want to listen to audio content while on the go.

HAVIT released its first air conduction headphones Freego1 Air this year. After the product release, Freego1 Air gains the favor of many consumers. Because it uses a lightweight design, it can be aware of surroundings in outdoor sports via open-ear design. It can be worn stably and offers a rich and natural listening experience.
