Magnet arrangement for loudspeaker
First Claim
1. An electro-dynamic loudspeaker comprising:
- a diaphragm having an electrical conductor coupled thereto;
a molded frame having a body defining a mounting plane;
a plurality of magnets at least partially embedded in the body of the frame, where the diaphragm is coupled to the mounting plane, and where each of the magnets is offset from the mounting plane.

Abstract
An electro-dynamic loudspeaker includes a frame, a plurality of magnets and a diaphragm. The frame includes a molded plastic body. The magnets may be molded into the frame in a determined configuration. The frame is mechanically coupled to the diaphragm such that the magnets are a determined distance from the diaphragm. The diaphragm may include a conductor applied to a surface of the diaphragm. The diaphragm may be driven by a motive force created when current passes through the conductor within a magnetic field formed by the magnets. The electrical current may be varied to create an acoustical output from the electro-dynamic loudspeaker.
