Driver assemblies, headphones including driver assemblies, and related methods
First Claim
1. A driver assembly, comprising:
- a housing structure;
a magnet assembly within the housing structure and comprising;
a permanent magnet;
a plate structure underlying the permanent magnet;
a voice coil circumscribing the permanent magnet and the plate structure; and
a yoke structure at least partially surrounding the permanent magnet, the plate structure, and the voice coil;
opposing spring structures coupled to the housing structure at different vertical positions than one another and configured to impede horizontal movement of the permanent magnet, the plate structure, and the yoke structure while permitting vertical movement thereof; and
a tubular structure provided within and vertically extending through aligned, centrally horizontally positioned apertures in the opposing spring structures and the magnet assembly.

Abstract
A driver assembly comprises a housing structure, a magnet assembly within the housing structure, and opposing spring structures coupled to the housing structure at different vertical positions than one another. The magnet assembly comprises a permanent magnet, a plate structure underlying the permanent magnet, a voice coil circumscribing the permanent magnet and the plate structure, and a yoke structure at least partially surrounding the permanent magnet, the plate structure, and the voice coil. The opposing spring structures are configured to impede horizontal movement of the permanent magnet, the plate structure, and the yoke structure while permitting vertical movement thereof. A headphone and a method of forming a headphone are also described.
