Derrick Rodgers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11336992
    Abstract: One or more embodiments of the present disclosure relate to a two-way loudspeaker design that forces a condensed geometry between low frequency (LF) and high frequency (HF) drivers and then “floats” a midrange waveguide in front of the LF driver. This is a hybrid design meant to benefit from the close proximity of acoustic centers without introducing a central axis obstruction for the LF driver. In addition, the LF and HF waveguides and associated acoustic elements are used to redirect very low frequency energy not supported adequately by the LF waveguide to exit freely using other paths.
    Type: Grant

  • Patent number: 10440465
    Abstract: A surface mounted loudspeaker design is provided that mitigates the interference between direct low frequency (LF) energy and reflected LF energy by breaking the LF energy from an LF driver into multiple paths using one or more of waveguides, driver load plates, and enclosure ports to diffuse the reflected energy and minimize frequency response errors. One or more embodiments of the present disclosure provides a loudspeaker have multiple acoustic exits strategically designed and located to generate, for example, three major wave front arrivals—2 source and 1 reflection—at target angles with favorable lag times, mitigating the cancellation notching and frequency errors that occur in conventional loudspeaker designs.

  • Patent number: 10375468
    Abstract: A speaker assembly rigging system is provided with a first frame and a second frame that is adapted to couple to the first frame. The system includes a cam and a link. The cam is pivotally connected to the first frame about a pivot point. The cam includes at least two cam surfaces, and each of the at least two cam surfaces are offset at a different radial distance from the pivot point corresponding to a splay angle. The link has a proximal end that is pivotally connected to the second frame and a distal end having a contact surface. The link extends from the second frame in a deployed position such that the contact surface engages one of the cam surfaces.

  • Patent number: 9014411
    Abstract: A speaker grille is provided including a front portion capable of sound transmission and side portions extending from the front portion. Each side portion includes an edge and a projection that extends beyond the edge, where each side portion has a substantially similar capability for sound transmission as the front portion. In one embodiment, the speaker grille comprises a perforated metal material, a fabric cloth material attached to the perforated metal material on an interior surface of the grille, and a metal cloth material attached to the fabric cloth material such that the fabric cloth material is disposed between the metal cloth material and the perforated metal material.
