ABSTRACT:
A dipole radiating dynamic speaker design comprises a diaphragm (32) providing a surface for radiating acoustic output, a voice coil assembly (36) for driving the diaphragm, and a magnet system for providing magnetic flux across the voice coil assembly. The speaker incorporates a vented pole flux conductor (42) and a vent adjacent to the diaphragm permitting the rearward acoustic output to propagate away from the diaphragm producing acoustic output as a dipole radiator.A method of utilizing the dipole radiating dynamic speaker design for tweeter and mid-range speaker applications used in home, automotive, and professional audio systems is disclosed. In addition a novel enclosure design is disclosed that utilizes a front panel perimeter vent providing improvement of audio reproduction quality for mid-range speaker applications.
