Abstract

A planar speaker system may include a bottom frame having a cavity. Within this cavity a plurality of magnets may be arranged to form a substantially circular pattern. A diaphragm that includes a plurality of electrically conductive traces may be connected to the bottom frame and extend across the cavity of the bottom frame. When alternating current flows through the electrically conductive traces, the diaphragm may vibrate in response to the interaction between the current flowing in the electrically conductive traces and the magnetic field, thereby producing sound. The planar speaker system may include a top frame having a cavity, and a second set of magnets may be disposed in the cavity of the top frame.

First claim

I claim:

1. A planar speaker system comprising:
a bottom frame having a cavity, where the bottom frame is substantially circular in shape and has an outer diameter and an inner diameter, and where the cavity of the bottom frame is substantially circular in shape;
a plurality of magnets disposed in the cavity of the bottom frame, the plurality of magnets circumferentially spaced to form a substantially circular pattern. the circular pattern coaxially aligned with a central axis…
