Product Overview
Our Neo Magnet Speakers magnets are sintered NdFeB elements made specifically for loudspeaker motor systems. They are supplied as discs, rings, blocks or custom profiles to match magnet housings and voice-coil assemblies. Compared with ferrite, these neodymium magnets for speakers allow smaller motor air-gaps and higher sensitivity in compact drivers.
Key specifications
- Material / grades: NdFeB, typical grades N35–N52 (grade selected per SPL / thermal requirements).
- Shapes: disc, ring, block, or custom profile for pole-piece assemblies.
- Magnetization: axial standard; radial or multi-pole patterns available on request.
- Coating: Ni-Cu-Ni standard; epoxy or Zn for specific environments.
- Tolerance: typical ±0.05 mm; tighter tolerances offered for automated assembly.
- Operating temp: standard up to ~80 °C; N-grade and coating choices can extend working range.
- Quality checks: batch Br measurement, coercivity check and dimensional inspection supplied with shipments.
What engineers care about
Compact motor design: small, strong magnets permit thinner drivers and higher SPL per unit volume.
Reproducible flux: we control magnetization and dimensional tolerances to avoid unit-to-unit acoustic variation.
Assembly fit: profiles are machined to fit press-fits or glue pockets used in speaker modules.
Typical applications
- Smartphone and tablet speakers
- Portable Bluetooth and battery-powered speakers
- Headphone and earcup drivers (mid and woofer elements)
- Miniature transducers for IoT and wearable devices
Procurement & customization
We support sample runs and scale to bulk supply for production programs. For OEMs we offer matched sets, magnetization mapping and traceable batch reports. Typical workflow: receive your drawing → produce samples for fit and acoustic testing → approve → enter mass production. Lead time for standard shapes: 2–4 weeks; custom tooling and large volumes vary by spec.
Packaging & logistics
Magnets are packed with non-magnetic separators and cushioning to avoid attraction damage. For high-volume orders we provide palletized, labeled trays ready for line feeding.
FAQ
Q: Can you tune magnet grade for specific SPL or temperature needs?
A: Yes-we advise grade and coating choices based on your acoustic target and thermal budget.
Q: Do you provide magnetization maps for multi-pole motors?
A: Yes-maps and polarity checks are included on request.
Q: Samples before bulk?
A: Standard practice-samples supplied for EMC, acoustic and assembly tests prior to volume orders.
