1. Field of the Invention
The present invention relates to a wall or ceiling mount and enclosed speaker box that is partially recessed and angularly oriented relative to the wall or ceiling.
2. Background Art
Audio speakers for broadcast music, recorded music players, and video entertainment systems are provided in a wide variety of types and styles. Audio systems may be designed for use in buildings, vehicles, or outdoor locations. Generally, audio speaker designs for a vehicle are not ideal for use in buildings. Likewise, audio speakers for use in homes, business, or other buildings are not appropriate for use in vehicles. Recreational vehicles such as motor homes, trailers, or boats are normally designed to provide all the comforts and convenience of home, however, speakers designed for use in buildings cannot usually be used in a recreational vehicle because they are not easily, or attractively anchored.
Typically, speakers used in buildings are provided as bookshelf speakers or floor supported cabinet speakers. Recently, bracket mounted cube or surround sound speaker boxes have been developed for mounting small enclosed speakers to a wall by means of a bracket. Brackets hold the speaker enclosure away from the wall to which they are secured. Bracket mounted speakers require space and are not well adapted for use in vehicles.
Speakers designed to be used in vehicles are generally flush mounted in a dashboard top, package shelf behind a seating area, or inside interior panels. Speciality vehicles such as motor homes, trailers and boats generally have speakers that are flush mounted to the wall or ceiling of the speciality vehicle. Flush mounted speakers cannot be aimed in that sound is focused in a direction that is perpendicular to the plane of the wall or ceiling to which the speaker is mounted. Flush mounted speakers are not generally adjustable and must be mounted within the space provided behind an interior wall or ceiling. Flush mounting arrangements impose some limits on acoustic performance. While bracket mounted speakers may be used in speciality vehicles, expensive brackets must be provided that increase the amount of space required and tend to be unattractive.
There is a need for a speaker mounting arrangement that is attractive and minimizes space requirements. There is also a need for a speaker mount that can be directed toward a listening position and that offers excellent acoustic properties that can be provided within enclosed speakers having internal baffling and wave guides. There is also a need for a speaker mounting arrangement that may be suitable for home or vehicle use and that is particularly well suited for use in speciality vehicles. These needs are addressed by applicant's invention as summarized below.
According to one aspect of the present invention, a speaker system is provided that is adapted to be secured to a wall. As used herein, the term “wall” when referring to the supporting surface to which the speaker system is secured is intended to include upstanding walls or a ceiling of a building or vehicle. The speaker system comprises an adapter that secures the speaker system to the wall and a speaker box that is secured to the adapter. The speaker box has at least one speaker secured to at least one speaker portal wall. The speaker portal wall is disposed in the plane that is oriented at an angle relative to the wall and is also disposed outboard of the wall.
According to another aspect of the present invention, a speaker and surface mounting apparatus combination is provided. A box-shaped enclosure structure having six sides is provided that has at least one side that is a speaker portal side. An audio speaker is secured to the speaker portal and is enclosed with the enclosure structure. A surface mounting adapter having a peripheral edge portion and a wall having a planar portion extending between the peripheral edge portion and the enclosure structure. Portions of at least four sides of the enclosure structure protrude from the planar portion of the wall, and other portions of the at least four sides of the enclosure structure are recessed relative to the planar portion of the wall. The speaker portal side is disposed outboard of the surface mounting adapter.
According to other aspects of the invention as they relate to the speaker and surface mounting apparatus combination or the speaker system described above, the entire side defining the speaker portal may be disposed outboard of the surface mounting adapter. Four or five sides may protrude in whole or in part from the wall. One of the sides defines the speaker portal side. Another side may be a back side that extends from a distal edge of the side defining the speaker portal to the planar portion of the wall. Another side may be a front side that extends parallel to the back side and partially protrudes from the planar portion of the wall to the side defining the speaker portal. A pair of side walls may be provided that extend between the front side, the back side, and the side defining the speaker portal. The back side may extend in the plane that is at an oblique angle relative to the planar portion of the wall while the front side may extend in a plane that is parallel to the back side and at an acute angle relative to the planar portion of the wall.
According to still further aspects of the invention, the planar portion of the wall may extend substantially diagonally across the side wall where the edge defined by the speaker portal wall and the back side is the portion that protrudes to the greatest extent outboard the planar portion of the wall. The surface mounting adapter may further comprise a recessed portion that is recessed relative to the planar portion of the wall. The recessed portion may have a first oblique wall and a second oblique wall that are obliquely oriented relative to the planar portion that partially receives two sides of the enclosure. This mounting adapter may also further comprise a recessed portion that is recessed relative to the planar portion. The recessed portion may have a first triangular wall and a second triangular wall that partially receives two side walls of the enclosure and are oriented perpendicular to the planar portion of the wall. At least a portion of the planar portion of the wall may be pivotally secured relative to the peripheral edge portion to permit the enclosure to be pivoted to directionally orient the speaker portal.
According to other aspects of the invention as they relate to a speaker system that is adapted to be secured to the wall, the speaker portal side may be entirely disposed outboard of the surface mounting adapter. The speaker box may further comprise a speaker portal side, a back side extending from a distal edge of the side defining the speaker portal to the adapter, a front side extending parallel to the back side and partially protruding from the adapter to the speaker portal, and a pair of side walls extending between the front side, the back side, and the side defining the speaker portal. The speaker box may have a back side that extends in a plane that is disposed at an oblique angle relative to the adapter, while the front side may extend in a plane parallel to the back side and oriented at an acute angle relative to the adapter.
These and other aspects of the invention will be better understood in view of the attached drawings and following detailed description of the best modes of practicing the invention.
