Product detail

  • Product Name:

    Ring Magnet

  • Model No: Ring Magnet

Description

Ring magnets are mainly used in loudspeakers and speaker drivers. Ferrite Ring magnets are main used for low energy and quality speakers, NdFeB ring magnets are gradually used for high energy and top quality speakers,earphones. The fast development in loudspeakers, earthphone or other audio equipment require very high energy neo magnet which has stable performance at high temperature. Our Neodymium N38SH ring magnets are proved to be the one of best choices. Our Neodymium N38SH material is used widely by JBL Professional in US.

As for high bonding power requirement for the magnets in assemblying to loudspeaker parts, surface tension of the coating is critical for magnet choice. Our trivalent chrome Zinc coating on neo magnets provide high surface tension and it is surely of environmental protection.
