21mm x 7mm x 5mm ferrite ring magnet for loudspeakers

This is a type of ring ferrite magnet, hard permanent magnet, with various anisotropy levels. The outer diameter of the magnetic ring is 21mm, the inner hole is 7mm, and the thickness is 5mm. It is uncoated and mainly used for speakers, speakers, and audio systems. Our company has many large or small, thin ring shaped neodymium or ferrite magnets for speakers, which are cheap. Welcome to your inquiry.

In a speaker or speaker, a permanent ferrite magnetic ring is usually used to construct a magnetic circuit system, which is responsible for generating a magnetic field and driving a vibrator or voice coil to produce sound. The shape and size of the magnetic ring may vary depending on specific design requirements, usually a circular or cylindrical shape.

The horn permanent ferrite magnetic ring has the following characteristics and advantages:

High magnetic permeability: It can generate a strong magnetic field, allowing the speaker or speakers to produce higher volume and better sound quality.

Stability: It can maintain magnetism even after the magnetic field disappears, making it difficult to magnetize or demagnetize, ensuring the long-term performance stability of the speaker or speaker.

High temperature resistance: able to work in high temperature environments without easily losing magnetism.

Corrosion resistance: It has good corrosion resistance to most chemical substances and extends its service life.

Cost effectiveness: Compared to other magnetic materials, horn permanent ferrite magnetic rings have lower costs and are suitable for large-scale production.
