  • Patent number: 5894524
    Abstract: A high power compact tweeter which includes a high energy magnet sandwiched between the base of a yoke and top plate which form the magnetic path, the magnet and top plate being spaced from side walls of the yoke by a predetermined gap. A voice coil is positioned in the gap. A heat sink is in thermal contact with the yoke to facilitate, preferably in conjunction with heat transfer management from the speaker.

  • Patent number: 5754667
    Abstract: An audio filter for use with loud speakers which substantially eliminates magnetic fields emanating from inductors of the filter by the inductors for each channel being physically oriented and electrically connected so that the magnetic fields generated by the inductors for each channel are self-cancelling. For preferred embodiments, the pair of inductors for each channel are side-by-side in close proximity to each other with current flowing in opposite directions through the coils.

  • Patent number: 4602382
    Abstract: An electro-acoustic transducer assembly includes a permanent magnet and a diaphragm having a voice coil bonded thereto. The assembly comprises a hollow casing having an opening formed in one surface thereof; a closure for covering the opening and comprising an aperture therein in which the diaphragm is mounted, and a cover mounted on one side of the closure for protecting the diaphragm, wherein the magnet is positioned on the opposite side of the closure in proximity to the voice coil on the diaphragm. The assembly also includes a latching assembly for releasably securing the closure across the opening in the casing in a latched position with the cover being positioned to the exterior of the assembly and the magnet being positioned in the casing, the latching assembly being operable by application of pressure at preselected locations on the periphery of said casing to release the closure from the latched position.
