SPEAKER MAGNET ASSEMBLY WITH INCLUDED SPIDER

摘要

A magnet assembly for a audio speaker provides a gap through which a voice coil assembly passes. A magnetic member, a yoke, and a pole piece form a magnetic circuit that focuses magnetic energy in the gap. A spider movably supports the voice coil assembly. The spider is coupled to one of the magnetic member or the yoke by forming the one of the magnetic member or the yoke in two parts and joining the two parts with a portion of the spider between the two parts. The spider may be formed from a thin film thermoplastic, such as polyetheretherketone (PEEK), and may be less than 10 microns thick. The portion of the spider that is between the two parts may be shaped such that a portion of the two parts are in direct contact with one another.

主权项

1. A magnet assembly for an audio speaker, the magnet assembly comprising:
a magnetic member; a yoke magnetically coupled to the magnetic member; a pole piece magnetically coupled to one of the magnetic member or the pole piece and forming one side of a gap through which a voice coil assembly passes, the magnetic member, the yoke, and the pole piece forming a magnetic circuit that focuses magnetic energy in the gap; and a spider that is coupled to one of the magnetic member or the yoke by forming the one of the magnetic member or the yoke in two parts and joining the two parts with a portion of the spider between the two parts.
