Abstract

A low-profile speaker that includes a low-profile frame, and a first magnet assembly disposed in the low-profile frame. The first magnet assembly has a first cage and a plurality of magnets disposed in the first cage. The low-profile speaker also includes a support assembly having a cone and a support ring attached to the cone, and a voice coil attached to the support ring. The support ring and voice coil are suspended in relatively close proximity to the magnet assembly such that the support ring and voice coil oscillate in response to electrical signals in the voice coil.
