Speaker magnet assemblies — magnet, T-yoke, plate and pole — are the magnetic circuits of loudspeakers, headphones, buzzers and transducers. We produce both full assemblies and the magnet components for speaker OEMs.
We supply ferrite ring assemblies for mid- and low-frequency drivers and NdFeB assemblies for compact high-efficiency speakers, with glue or mechanical fixing as specified.

All magnets are produced to order. Please provide grade, dimension (or drawing), magnetization direction, coating and quantity for quotation. Email sales@polemagnet.com or use the inquiry form — we reply within 24 hours.
FAQ
Speaker Magnet Assemblies — FAQ
Do you supply complete speaker magnetic circuits?
Yes, we supply complete assemblies including magnet, T-yoke, top plate and pole, with air-gap control for consistent speaker performance.
What magnet suits a high-power woofer?
Ferrite ring magnets with large cross-section are typical for woofers; NdFeB is used where magnet size is constrained. We can model the circuit for your target BL product.
Do you provide free samples for testing?
Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.
Can the factory produce to my drawing with special tolerances?
Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.
