What is speaker coil? Structure of speaker coil

Coil speaker, also known as cone speaker, it is the voice coil of the speaker . The speaker cone is made from a metal wire core with countless different windings, forming a vertical prism .

The structure of the speaker cone is very simple, but the device plays a very important role to support the speaker to operate well. Speaker coils are present in any speaker line, helping to generate a strong magnetic field for the magnet. Thanks to that, the device can work at its best, providing excellent sound quality for listeners.

Working principle of speaker coil

When current is passed, the coil generates an induced current in the closed circuit. The magnetic field is generated in the coil, due to the effect of the magnetic field of attraction and repulsion of the magnet. Thanks to the induced electromotive force combined with the magnetic force of the magnet to rotate alternately and continuously, the coil moves up and down steadily.

At that time, the diaphragm is also affected and moves rhythmically. The moving diaphragm causes the particles in the air to do the same and causes them to move and generate sound waves. These sound waves are propagated into the air and into the listener’s ear.

The way it works is also how the sound from the speaker reaches the listener. Through the principle of operation of the speaker coil, we see that the speaker coil has a very important role, whether in small sound systems such as at home or large sound systems such as hall sound, stage sound.

Speaker for clear, clear sound, without distortion as desired, then you have completed the correct steps and used the device normally.

On the contrary, the results do not give the desired sound quality, please check the above steps again.

Notes when changing speaker cones

In the process of replacing the speaker cone, in order to ensure that the user follows the correct steps and successfully replaces the cone, it is necessary to note some of the following issues:

• Speaker cone must be new: Go to reputable stores and choose for yourself a new and high quality speaker coil to replace the speaker. It will help increase durability and sound better, better quality.
• Choosing the right speaker coil for the device you are using: This is an important factor and determines whether the sound quality is exactly what you want or not. Each type of speaker is manufactured with different equipment, so users should choose according to the set standards. For example, you cannot use a computer speaker coil to install a high-powered speaker.
• Clean all equipment before installation: Make the sound quality better and better.
• Regularly check and replace the speaker cone when needed, because it will directly affect the sound.
