This is a ring-shaped ferrite magnet with an outer diameter of 21mm, an inner diameter of 7mm and a thickness of 5mm. It is uncoated and is mainly used for speakers. Our company has many large and small ring magnets for speakers. The price is cheap. Your consultation is welcome.
Ferrite is generally made into an external magnetic speaker. The magnetic performance of ferrite is relatively low, and a certain volume is required to meet the driving force of the speaker, so it is generally used in larger audio speakers. The advantage of ferrite is that it is cheap and cost-effective; the disadvantage is that it is large in size, small in power and narrow in frequency range.
