The paper cone of the speaker is generally made of plant fiber materials. As the main component of the speaker, the paper cone has the function of assisting the speaker voice coil to radiate sound, which largely determines the sound quality of the speaker.

The paper cone of the speaker, also known as the sound cone, is a common type of diaphragm. Although it is called a paper cone, there are many kinds of materials used, which can basically be divided into two categories: natural and artificial materials. No matter what material is used for the paper cone of the speaker, it must meet a basic principle of using the paper cone, which is light weight, good rigidity and not easy to deform. The main advantage of the paper cone is that the internal fibers are intertwined with each other, and in the process of sound transmission, the energy absorption is faster, the damping characteristics are more ideal, the sound is natural and smooth, and there is no distinctive part, which conforms to the taste of the public. However, due to the characteristics of its material, it is more sensitive to temperature and humidity, and changes in the environment may affect the sound of the speaker.

Some of the main factors that affect the life of the paper cone:

Environmental conditions: Humidity or extreme temperature environments may cause the paper cone material to age or deform, thus shortening its life.

Frequency and volume of use: Long-term high-volume use will increase the burden on the paper cone and accelerate its wear.

Material quality: High-quality paper cones are generally more durable and have a longer life.

Why you need to replace the paper cone of your speaker:

Material aging: Over time, the paper cone material may become brittle, crack or deform, resulting in a decrease in sound quality.

Physical damage: The paper cone may be damaged by impact, excessive use or other physical factors.

Sound quality issues: Aging or damaged paper cones may cause sound quality distortion or loss of original sound performance

Tools and materials required

Replacement cone (make sure it matches the original)

Hot melt glue gun or glue

Screwdriver

Soldering tool (if you need to replace the voice coil)

Cleaning agent (for cleaning up the old glue residue)

Brush or soft cloth

To disassemble the speaker:

Turn off the speaker power and disconnect all connections.

Use a screwdriver to disassemble the speaker housing and remove the speaker unit from the speaker.

Remove the old cone:

If there is a dust cover on the speaker, carefully remove the dust cover first.

Use a blade or tool to carefully peel off the connection between the old cone and the bracket (or basin stand). If there is glue or welding points between the cone and the voice coil, handle it carefully.

Clean up the residue:

Use a cleaner and a brush to remove the old glue and dust on the speaker bracket and ensure that the surface is clean.

Install the new cone:

Align the new cone with the bracket to ensure the correct position.

Use hot melt glue or suitable glue to fix the cone to the bracket.

If the voice coil needs to be replaced, use a welding tool to connect the new voice coil.

Restore other parts:

If the dust cover was removed, reinstall it after the cone is installed.

Make sure all parts are stable and the cone can vibrate freely without obstruction.

Test:

Reinstall the speaker back into the speaker, connect the power supply and test to ensure that the sound is normal and there is no noise.

Final assembly:

If the test passes, finally reassemble the speaker housing, making sure all screws are tight.

Notes

Be careful when handling the cone to avoid damaging the new cone during installation.

The glue used should be suitable for the audio equipment to ensure that it does not come loose during vibrations.

If you are unsure about the operation, it is recommended to seek the help of a professional technician, especially when it comes to high-end audio equipment.
