Speaker magnet sourcing
Many speaker projects start with one question: should the magnet be ferrite or NdFeB? The answer depends on product size, sound unit design, target cost, and how much magnetic force the assembly needs.
Ferrite magnets are common in many speaker designs because they offer stable cost and repeat supply. NdFeB magnets are useful when the speaker needs a smaller magnet with stronger force.
CIYI can review speaker magnet requests from size, drawing, target force, material preference, and order quantity.
The magnet is only one part of the speaker assembly. Before confirming price, it helps to know the outside diameter, inside hole, thickness, material, coating if needed, and how the part will be packed.
Comparison
Both can work. The product design decides which one makes sense.
| Magnet type | Good fit | Quote details |
|---|---|---|
| Ferrite ring magnets | Cost-sensitive speaker parts, larger assemblies, repeat bulk orders. | Outer diameter, inner diameter, thickness, magnetization direction, quantity. |
| NdFeB disc or ring magnets | Compact speakers, smaller parts, stronger force in limited space. | Grade, coating, size, tolerance, temperature concern, packing. |
| Custom shapes | Non-standard speaker modules or assembled magnetic parts. | Drawing, sample photo, surface requirement, annual demand. |
Quote checklist
If you do not know every item, send what you have. A photo and rough size are enough for the first discussion.
Speaker magnet FAQ
These answers keep the first inquiry practical.
Ferrite is often better for cost and stable supply. NdFeB is better when the speaker design needs stronger force in a smaller size.
Yes. Send outer diameter, inner diameter, thickness, magnetization direction, quantity, and packing requirement.
Ferrite magnets usually do not need the same coating discussion as NdFeB. NdFeB magnets often need nickel, zinc, epoxy, or another coating depending on use.
Yes. A sample or clear photo helps. A drawing is better if tolerance, hole size, or assembly fit matters.
Test reports or compliance documents can be discussed by order requirement.
