  • Publication number: 20110007921
    Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, a method is provided for mounting a loudspeaker driver in a loudspeaker driver aperture defined in a ground plane and installing a grille in relation to the ground plane such that a distance between the grille and the ground plane decreases as the distance from the loudspeaker driver increases. In accordance with at least one embodiment, apparatus is provided comprising a ground plane, a loudspeaker driver mounted in a loudspeaker driver aperture of the ground plane, and a grille positioned relative to the ground plane such that a distance between the grille and the ground plane decreases with increasing distance from the loudspeaker driver. The loudspeaker assembly can be used to replace ceiling tiles having any size or configuration, and can also me mounted in other surfaces, such as ceiling walls, floors, table tops, etc.

  • Patent number: 7861825
    Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, a method is provided which comprises forming a loudspeaker frame so as to define a driver housing portion, a horn portion, and a conformal portion. A driver aperture is defined for the driver housing portion, and a port aperture is defined for the horn portion. A driver is attached to the loudspeaker frame proximate to the driver aperture. A rear baffle is applied to a first conformal portion surface of the conformal portion of the loudspeaker frame. The rear baffle defines a horn cavity wall of a horn cavity of the horn portion. The horn cavity has an increasing cross sectional area as the distance from the driver housing portion increases. A grille is applied to a second conformal portion surface of the conformal portion of the loudspeaker frame.

  • Patent number: 7455271
    Abstract: A speaker mount includes a support structure attachment, an adjustable mount connected to the structure attachment and including a first connector, and a speaker attachment including a second connector. The first and second connectors may selectively be connected or disconnected, permitting a speaker to be connected to and disconnected from the remainder of the mount. The first connector is mounted to a ball. A lock plate is mounted at an opposing side of the ball from the first connector. A fastener controls the distance between the first connector and the lock plate. In one position, the fastener draws the lock plate and first connector towards one another, fixing the lock plate in a position on the ball, and in another position allows the first connector to be moved relative to the ball. The mount permits orientation of a speaker in a variety of positions relative to a support structure.
