BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates generally to audio/video entertainment systems, and more particularly, to wall mounting of audio/video entertainment systems.
2. Description of Related Art
Modern multimedia systems such as audio-visual (AV) entertainment systems are increasingly used both in commercial and in residential settings. In the commercial sphere, high-end multimedia systems are installed in conference rooms and hotel rooms, for example, whereas in the residential sphere, integrated entertainment systems that can provide a credible home cinema experience are becoming popular. Multimedia systems typically integrate multiple components such as a display device (e.g., a high-definition television or HDTV, a projector and projector screen, or an LCD screen, LED screen or plasma screen), a loudspeaker system (e.g., 2.0 or 2.1 stereo, 3.1 channel or 5.1/7.1 surround sound configurations), and a signal source (e.g., a radio tuner or TV receiver, satellite receiver, compact disk or CD player, set-top box, IP-based Internet device, an optical disc player such as a DVD or Blu-ray player, a digital video recorder or DVR, and/or a video game console). A multimedia system may further include components or equipment that provides remote control or management, communication, computing, signal processing, switching, amplification and/or power supply functions. In many cases, these and other system components and equipment may be sourced from a variety of commercial vendors and are integrated manually and configured by multimedia system installers to form the multimedia system.
The integration and installation of such multimedia systems raises concerns for the design community (e.g., architects, interior designers), for builders and developers, for equipment installers, and even for end users (e.g., home owners, renters or hotel guests) about how equipment will be mounted or housed, how much space it will take, whether the end result is aesthetically pleasing, and whether it will be possible to upgrade or service the system with relative ease in the future, for example, by replacing or adding components. Further, the equipment must be adequately ventilated to allow for heat dissipation. Finally, it must produce high quality audio and/or video output.
It is especially difficult to address the above concerns given that consumers have strong but divergent preferences regarding which components should be integrated into their multimedia system and specifically how they are integrated or configured. One approach has been to use special furniture or custom millwork for multimedia system installations to address a consumer's aesthetic requirements (e.g., to match room décor) while facilitating flexibility in installation, integration and serviceability of the system. Unfortunately, such installations occupy valuable floor space and are often inelegantly bulky.
In-wall multimedia system installations, on the other hand, while saving on floor space and bulk, lack flexibility for accommodating a consumer's component preferences because many commercial off-the-shelf components cannot be easily mounted inside the confined space of a wall, and moreover, in-wall installation of such components may cause heat dissipation problems that can damage the system. In-wall multimedia system installations further tend to lack upgradability and serviceability due to the typical permanence of in-wall installation and the subsequent lack of access to in-wall system components.
It would be desirable to provide a mounting apparatus for a multimedia system and related methods and systems to address some of these concerns.
SUMMARY
Certain embodiments of the present invention provide advantages not provided or only partially provided by the known prior art, and address the aforesaid disadvantages and other disadvantages of the known prior art.
In certain embodiments, the AV system may be mounted such that substantially the entire the AV system (other than the display device) is contained within a confined space, for example, within a standard 4′′ stud wall, with only the display device and wall opening cover being visible to the viewer. The in-wall components in one embodiment may actually fit within about a 3.5′′ depth confined in-wall space, for example, on a yacht, or in any larger space.
Embodiments of the invention may include a cover for concealing a portion of the confined space, dimensioned to cover at least a peripheral portion of an in-wall space at least partially enclosed by an in-wall mounting frame, and adapted to be removably connected to the in-wall mounting frame. An outer edge of the cover may be dimensioned to extend beyond the perimeter of the display device so as to visually frame the display device to the viewer. To the viewer, the mounted display device visually appears to “float” on the wall with no immediately apparent means of attachment. The cover may be chosen to have a color or visual design that blends with existing room décor.
Advantageously, the use of a removable cover to conceal a peripheral portion of a finished wall opening that would otherwise be visible to a viewer, allows embodiments of the invention to provide a relatively large, user-accessible support space within the confined space for supporting/mounting in-wall components. The user-accessible support space may be dimensioned larger than the display device, contrary to one industry trend in which display mounting components are made to have a substantially smaller footprint than the display so that the display device can conceal them.
Advantageously, embodiments of the invention may avoid the need for custom millwork or custom cabinets to hold devices associated with the AV system, nor is it necessary to make multiple cuts or installations of components within discrete non-conjoined portions of the wall.
Alternatively, embodiments of the invention may be built into articles of furniture or cabinets having very limited depth or providing only a confined space within which to situate components of the AV system, such that only the display device and a cover is suspended from a vertical wall of the furniture in front of an opening into the confined space where the AV components are housed.
In certain embodiments, the mounting system may be capable of supporting display devices from about 46 inches to about 65 inches diagonally, and is adaptable to support display devices outside this range, for example, by scaling the support member and wall opening cover to a suitable size.
Embodiments of the invention may simplify prewiring installation by providing dedicated connection points for electrical and low-voltage wiring.
In certain embodiments, the entire AV system may be powered by a hidden in-wall power distribution module providing individually controllable AC power outlets for individual signal source components and the display device, as well as low voltage power connections to other components in the system. One benefit of this arrangement is that end users can control (e.g., turn on/off) the power to individual components without having to access the in-wall space.
Embodiments of the invention may include at least one integral or removable mounting panel that supports multiple local AV signal source components in a hidden confined space proximate the display device. Alternatively, or in addition, the mounting panel may support one or more signal distribution devices and/or amplification devices within the in-wall space.
Advantageously, embodiments of the invention may modularize the design of an AV system by omitting certain AV components from the display device that would perhaps otherwise be integrated with the display device, and instead locating these components in a hidden in-wall space. For example, some embodiments can obviate the need for a TV display to contain speakers since speakers can be embedded in the wall behind the TV. Consequently, the display device can be made thinner and less costly. In addition, components can be implemented within the wall in a way that takes advantage of the thickness and height and width of the support space available in the wall, thus allowing higher quality components to be used than would otherwise be used if these components had to be embedded in the display device. One example is that in-wall speakers can be of higher quality than the speakers in a TV.
Accordingly, some embodiments of the invention may provide a compact, elegant and unobtrusive system installation for providing high quality entertainment or cinema-like experiences, and may include, for example, a display, high performance front loudspeakers and multiple surround loudspeakers, state-of-the-art multi-channel power amplification, switching and distribution of multiple audio and/or video sources, audio processing and decoding for existing Dolby and DTS formats (and adaptable to others) with power distribution and surge protection for all electronics. Any electronics (including speakers) embedded in the wall are hidden from view while in use by an attractive removable cover, yet such components remain accessible, serviceable, and upgradeable to a service technician upon removal of the cover.
Embodiments of the invention may include dedicated pathways and connection points for electrical, audio, video, speaker level, data and communication, to simplify prewiring and installation and eliminate any possibility for miswiring internal components. For example, one or more of the power distribution module, power amplifier, the signal processor, and the plurality of speakers may include connectors operably configured to mate with complementary connectors electrically connected to a common power and signal distribution circuit, to provide a quick, neat, simple and reliable method of interconnecting these components correctly via the distribution circuit notwithstanding the limited space available for making such interconnections.
The system may be readily upgradeable in terms of its looks by unsophisticated persons such as interior designers, and in terms of its hardware, by unsophisticated service technician due to the modularity of system components and the plug-and-play simplicity of their interconnection. For example, because the cover is removably mounted, it may be upgraded by an interior designer to provide a new look by ordering a cover with a new designer fabric. To take another example, because a substantial number of the in-wall components of the system are readily accessible from outside the wall and are removably mounted, the components can be upgraded quickly and easily by a relatively unskilled service technician with extremely low risk of error.
Apart from supporting simple switching or multiplexing between two or more AV signal sources, the signal processor may support more sophisticated processing, including decoding of HDMI 1.4, HDCP 2.0, 3D, ARC, and all major Dolby® and DTS® surround formats. However, as new formats and standards are developed, the system may be upgraded by replacing its hardware (as described above) or by installing new software into the signal processor.

DETAILED DESCRIPTION
Referring to FIG. 1, an audio-video system according to one embodiment of the invention is shown generally at 10. The system 10 includes a mounting apparatus 12 for mounting the audio-video system to a wall support 16 located behind a wall surface 104 in an in-wall space 18. The mounting apparatus 12, and thus the system 10, includes a support member 20 for supporting at least one component in a support space 22 within the in-wall space 18, a display mounting member 30 for mounting a display device 40, and a cover 100 for concealing at least a portion of the in-wall space 18 that would otherwise be visible to a viewer positioned outside the wall 14 to view the display device 40, for example, a person sitting in the room and watching TV on the display device 40.
In the embodiment shown in FIG. 1, the system 10 includes a plurality of devices and components supported by the support member 20 in the support space 22 within the wall. The devices and components that are supported by the support member 20 may be mounted directly to the support member 20, or may be indirectly supported by the support member 20 through a mounting mechanism, for example, they may be mounted to a removable mounting panel or bracket that, in turn, is supported by the support member 20.
The embodiment shown in FIG. 1 includes a power distribution module 50, a multi-channel audio power amplifier 60, a signal processor 70, one or more signal source devices 110, 112, and a plurality of speakers 80 including a subwoofer 180, all supported by the support member 20 in the support space 22. The system 10 further includes a display device 40 mounted outside the support space 22 and outside the wall 14 and configured to cooperate with the components and devices within the support space 22 to produce a coordinated audio-visual presentation to the viewer.
In general, the system 10 includes a video subsystem and an audio subsystem. The video subsystem includes any internally-supported signal source devices or external signal sources that provide video signals, the display device 40 and the signal processor 70. The audio subsystem includes any internally-supported signal source devices or external signal sources that provide audio signals, as well as the power amplifier 60 and the speakers. The embodiments where the signal processor 70 is capable of processing (including switching) both audio and video, it forms a part of both the audio and video subsystems. The signal processor 70 may include an AV preamp and/or a digital signal processing (DSP) circuit for transforming the audio- or video-stream.
The power distribution module 50 provides AC power and low-voltage power to various devices and components of the audio-video system 10.

The system 10 includes a mounting apparatus 12 for mounting an audio-video (AV) system 10, the mounting apparatus 12 including a support member 20 operably configured to support at least one component of the AV system 10 in a support space 22 adjacent the support member 20. The support member 20 is adapted to be mounted to at least one wall support, to which a final wall surface 104 will be attached and by which the wall surface is supported in a position between a floor and the ceiling of the room. In the embodiment shown in FIG. 3, the wall surface 104 is supported with wooden wall supports, namely, a plurality of vertically oriented 2×4 wooden studs spaced apart 16 inches on center. In other embodiments, the wall support could be different, for example, it could include a steel stud or poured concrete. In other contexts, for example, on a yacht, the wall 14 may include aluminum or fiberglass supports, to which the mounting apparatus 12 may be secured.
FIG. 3 also illustrates how, in one embodiment, the mounting apparatus 12 for mounting an audio-video system 10 would be installed at an early stage of construction of a wood-framed building, before the installation has commenced of the ultimate wall surface 104, which may be typically gypsum wallboard or drywall. It will be appreciated that if an already built wall is renovated or retrofitted in accordance with the present invention, it may be necessary to remove at least a portion of the existing wall surface 104 in order to connect the support member 20 to one of the wall supports. Advantageously, in this embodiment, it is unnecessary to cut out multiple sections of drywall from different areas of the wall 14; only one continuous section of the wall surface 104 is removed in order to provide an opening 102 in the wall surface through which the support member 20 can be inserted into the in-wall space 18 and secured.
Support Member
Referring now to FIG. 4, a support member 20 of the mounting apparatus 12 is shown according to one embodiment. The support member 20 is operably configured to support a plurality of components and devices in an adjacent support space 22, and is further configured to be installed (together with any items supported in the support space 22), into an in-wall space 18 within a wall, for example, by being mounted to a wall support, such as a wooden wall stud. Alternatively, items may be mounted to be supported by the support member 20 in the support space 22 after the support member 20 has been installed in a wall.
The support member 20 in the embodiment of FIG. 4 includes a generally box-shaped frame constructed of high-quality powder coated steel or another suitable material. The support member 20 has a top side, a bottom side, a left side, a right side, a front side and a rear side. The front side of the support member 20 is generally open to provide a support space 22 for holding components. The rear side of the support member 20 includes a sheet or plate to which components may be mounted. The left and right sides include respective left and right flanges that may be used to mount the support member 20 to a wall support. The support member 20 includes a plurality of multi-conductor connectors including a connector for a power distribution module 50, a connector for an AV preamp or processor, a connector for a multichannel audio amplifier, and a plurality of connectors corresponding to respective loudspeakers that may be mounted on the support member 20. The support member 20 further includes a transversely oriented guide member operable to help guide a plurality of components to align with and connect to the aforesaid connectors. For example, as shown in FIG. 11, the guide member helps to align the power amplifier 60 and a plurality of loudspeakers to mate with the corresponding connectors on the support member 20. A bottom side of the guide member forms an upper portion of a channel for receiving the loudspeakers into mounted position on the support member 20. In this embodiment, the guide member includes a shelf spanning and connected to the left and right flanges.
Referring back to FIG. 4, the support member 20 in this embodiment is dimensioned to be installed into any location with a minimum depth of about 3.5 inches to about 4 inches or greater. This support member 20 depth is compatible with the vast majority of both new construction and renovation applications in North America that typically used 2′′×4′′ inch nominal wall framing as a minimum. In this embodiment, a rough opening 102 in the wall framing of about 48′′×48′′ is used to support a wide range of display device 40 sizes of about 46 inches to about 65 inches in one embodiment. Once the support member 20 has been installed within the wall, a portion of the wall surface 104 may be replaced such that the final opening 102 in the wall surface is less than the initial 48′′×48′′ opening. Once installation of the system 10 is complete, the opening visible to a viewer of the display device 40 is only slightly larger than the outer dimensions of a television or other display device 40.
Depending on the embodiment, the support member 20 may include dedicated spaces, mounting points, alignment guides and, in some cases, connections for the subwoofer 180, LCR speakers 80, power distribution module 50, AV pre-amp/processor, power amplifier 60, an AV signal source mounting plate, a wall surface interface member, a display mounting system, or some combination thereof. The support member 20 may include dedicated junction boxes, conduit openings and/or connection points to allow the installation and connection of the required electrical power at the pre-construction stage, prior to the installation of the final wall surface (typically gypsum wall board or similar). These items may be an integral or permanent part of the support member 20 or may be removably mounted. Likewise, the support member 20 may provide these or analogous features to facilitate low voltage connections being made in the support area by an electronic systems contractor or service technician.
The support member 20 provides an access region for accessing items supported by the support member 20. In this embodiment, the access region includes an open side portion of the support member 20 operable to register with a corresponding wall opening 102 when the support member 20 is installed in a wall, to facilitate access to the line voltage and low-voltage connections (and other internal components) for service through the wall opening 102 even after installation of the wall surface. As will be described below, in normal use, the wall opening 102 is kept hidden behind the display device 40 and/or the cover 100.
Subwoofer Mount
Referring to FIGS. 5 and 18, in some embodiments, the support member 20 may include a subwoofer mount 182 for mounting a subwoofer 180 in the support space 22. The subwoofer mount 182 may include a subwoofer mounting bracket that is positioned or attached to the top side of the support member 20 and is further affixed to the wall support 16. The subwoofer mount is configured to slidingly receive the subwoofer enclosure into an operating position thereby permitting the installation of a subwoofer loudspeaker after the final wall surface has been installed and after installation of the support member 20 in the wall.
In one embodiment (FIG. 5), the subwoofer mounting bracket includes integral threaded mounting points and associated speaker support clamps to provide the ability to adjust the vertical positioning and placement of the subwoofer. In another embodiment (FIG. 18), the subwoofer mount includes a self-aligning mechanism including centering pins on the subwoofer mounting bracket that are adapted to cooperate with a corresponding guide on the sides of a subwoofer enclosure to progressively align the subwoofer enclosure as it is pressed into its final centered mounted position.
Installation of the subwoofer enclosure in the latter embodiment is further illustrated in FIG. 26. FIG. 26 provides a series of five side sectional views illustrating (from left to right) the progress of installation of the subwoofer enclosure at five consecutive points of time. The subwoofer enclosure is pressed against the back surface of the support member 20 and lifted upwards until a first centering pin on the subwoofer bracket enters a funnel-shaped first portion of the guide on the side of the subwoofer enclosure. Further movements of the subwoofer enclosure in the installation direction cause the enclosure to be centered due to the first centering pin entering a more constricted portion of the guide. Further upward movement of the enclosure causes the first centering pin to move along the guide in a nonlinear path defined by second, third and fourth portions of the guide, each defining a path oriented at a slightly different angle. As the enclosure moves towards its final operating position, the second centering pin enters the funnel-shaped portion of the guide. Eventually, the first and second pins come to rest in the fourth and second portions of the guide, respectively, whereby the subwoofer enclosure is held in its final operating position, precisely centered within the mount and also within the in-wall space, such that the enclosure is spaced apart approximately equally from the inner wall surfaces on either side of it. In another embodiment, the guides could be implemented on the subwoofer mounting bracket with the centering pins being on the enclosure.
Vertical adjustment of the subwoofer loudspeaker allows the installer to precisely align a subwoofer driver opening from which sound will exit, between the top of the display device 40 and an upper edge of the support space cover 100 in order to minimize the blockage of sound from the subwoofer by the display device 40.
In this embodiment, vertical adjustment of the subwoofer loudspeaker allows the support member 20 to accommodate display devices 40 of various sizes without the display device 40 interfering with the sound output from the subwoofer. Moving the subwoofer to a higher position opens up a portion of the support space 22 below the subwoofer, and this support space 22 portion may be used to support other system components. Moving the subwoofer to a lower position reduces the vertical dimension of the wall surface used by the system 10 in cases where a smaller display devices 40 is used, thereby reducing the overall footprint of the installation. In some embodiments, the mounting position of the subwoofer may be horizontally adjustable, or the subwoofer may be located in a different location, such as the bottom side of the support member 20.
The subwoofer mount may include a physical means of isolating it from the support member 20 and the structure of the wall (or a different kind of mounting cavity). For example, referring to FIG. 18, the subwoofer mount may be isolated from the points to which it is affixed by vibration isolators which may include PVC/rubber/neoprene isolation grommets added at the mounting points of the subwoofer mount, for example, the point at which the subwoofer mount is screwed into the support member 20 at one end and the wall supports (e.g., wood framing of the wall) at the other end. The vibration isolators provide a single mounting hole for affixing but are also designed such that no actual physical contact is made between the subwoofer mount and the support member 20 or framing support structure (see FIG. 18).
The subwoofer mount may also include subwoofer centering pins 198, 199. These pins, along with a corresponding slot opening 186 in both ends of the subwoofer enclosure, cooperate to precisely position the enclosure in the centre of the available space such that it does not make physical contact with the front or back wall surfaces. This embodiment is designed to create physical separation between the subwoofer enclosure and the wall surfaces, further reducing the transmission of vibration from the subwoofer enclosure to the surrounding wall structure. A foam isolation strip may be located in the narrow space between the side of the subwoofer enclosure and the subwoofer mounting bracket to further reduce any transmission of vibration to the wall.
Distribution Circuit
The system 10 may include a distribution circuit 90, supported by the support member 20, for distributing both low voltage power and various signals to selected components mounted on or to the support member 20.
The distribution circuit 90 may include an integrated signal and power bus or backplane interconnecting a plurality of spaced apart system devices. The distribution circuit 90 may include one or a series of heavy duty printed circuit boards installed in the lower portion of the support member 20 (e.g., the connectors shown in FIG. 17 connect to the distribution circuit 90). In one embodiment, the distribution circuit 90 includes connections and signal pathways for a variety of signal types including low voltage power, speaker level signals, digital and/or analogue control signals, digital and/or analogue audio and/or video source signals, and Ethernet or other forms of data signals. This arrangement allows the internal devices within the support space 22 supported by the support member 20 to be directly connected to one another through the pathways on the integrated signal and power bus, thus obviating the need for bulky wiring and enabling the full depth of the equipment mounting member to be exploited for mounting internal components, while also reducing the need for interconnection wiring and the risk of devices being connected improperly. Suitable connectors pairs for connecting the power distribution module 50, power amplifier 60 and/or the signal processor 70 to respective points of the distribution circuit 90 may be chosen, for example, from the SamtecTM MPT, MPS, MPTC, and MPSC series of complementary connectors, which may include both straight and right-angled versions of the connectors.
Referring to FIG. 17, a plurality of connectors are mounted adjacent the shelf 62 for interconnecting the power distribution module 50, the multichannel power amplifier 60, and the signal processor 70, through a distribution circuit 90, which may include a backplane implemented using one or more printed circuit boards and mounted to the support member.
Referring now to the connectors mounted above the shelf 62, connector 512 connects the power distribution module 50 to the distribution circuit 90 and connects to the multi-channel power amplifier 60 through connector 514 and to the AV signal processor 70 through connector 714. Connector 514 connects the multichannel power amplifier 60 to the distribution circuit and connects low voltage power signals from the power distribution module 50 through connector 512. Connector 714 connects the AV signal processor 70 to the distribution circuit and connects low voltage power signals from the power distribution module 50 through connector 512. In some embodiments, more than one level of low voltage power may be supplied over the distribution circuit.
Connectors 612, 614, and 616 cooperate to connect the multichannel power amplifier 60 to the distribution circuit 90. These connectors carry speaker level audio to the left channel speaker through connector 830, to the center channel speaker through connector 850, to the right channel speaker through connector 870, and to the subwoofer and/or the surround speakers through connector 716 to connections mounted at the top of the signal processor 70 enclosure.
Connector 712 connects the multichannel power amplifier 60 to the distribution circuit, and carries digital control signals as well as digital audio signals from the AV signal processor 70 through connector 714. Connector 714 connects the AV signal processor 70 to the distribution circuit, and carries both digital control signals and digital audio signals to the multichannel power amplifier 60 through connector 712. Connector 716 connects the AV signal processor 70 to the distribution circuit, and carries speaker level audio from the power amplifier 60 through connectors 612, 614 and 616 to the subwoofer and surround spakers at the top of the AV signal processor 70 enclosure.
Referring now to the connectors mounted below the shelf 62, connector 830 connects the left channel speaker to the distribution circuit and carries speaker level audio from the power amplifier 60 through connectors 612, 614, and 616. Connector 850 connects the center channel spaker to the distribution circuit, and carries speaker level audio from the power amplifier 60 through connectors 612, 614 and 616. Connector 870 connects the right channel speaker to the distribution circuit, and carries speaker level audio from the power amplifier 60 through connectors 612, 614 and 616.
Line Voltage Connection Member
Referring to FIG. 6, the support member 20 may further include a line voltage connection member 120, located within the support space 22 of the support member 20. In this embodiment, the line voltage connection member 120 may include a metal enclosure with a removable front cover held in place by fasteners such as machine screws. The line voltage connection member 120 provides a dedicated physical location in the support space 22 for termination of line voltage electrical power entering the support member 20 for use by components in the support area. Once the support member 20 has been mounted to the wall support, an electrical contractor can run the required electrical power conductors to this location, and connect them within the enclosure to a line voltage receptacle accessible from an outer surface of the line voltage connection member 120. Once the electrical circuit connection is complete, it can be tested and verified. This allows the electrical contractor to complete his work very early in the construction process and removes the requirement for any further involvement by the electrical contractor in the process of system installation. A power cable can then be connected to the line voltage receptacle and used to provide power to the power distribution module 50, which in turn can provide line and low-voltage power to other components of the system 10.
Low Voltage Connection Member
Referring to FIG. 7, the support member 20 further includes a low-voltage connection member 130. In this embodiment, the low-voltage connection member 130 is mounted to the support member 20 and includes a metal enclosure with a removable front cover held in place by fasteners such as machine screws. The low-voltage connection member 130 provides a dedicated physical location in the support space 22 for the termination of low-voltage cables and services entering the support member 20. On its outer surface, the enclosure may provide a plurality of low-voltage receptacles and connectors for making low-voltage signal connections. Once the support member 20 has been mounted to the wall support, an electronics systems contractor or other installer can run the required low voltage cables to this location, and make good and test all connections. Alternatively, the contractor or installer may leave the cables coiled for future termination during final installation. This connection member 130 is operatively configured to be used to provide low-voltage signals (including, but not limited to, AV, Data, CATV, Contact Closure, IR/Serial/IP Control, Speaker/Line Level audio) to system components as desired.
Power Distribution Module
Referring to FIG. 8, the support member 20 may further support a power distribution module 50. In this embodiment, the power distribution module 50 is a dedicated power distribution and management device located in the support space 22, and mounted to the support member 20 by means of fasteners such as machine screws. The power distribution module 50 includes a dedicated power cable having a plug which provides a locking connection to the line voltage receptacle 122 of the line voltage connection member 120, thereby providing electrical power to the power distribution module 50. In this embodiment, the power distribution module 50 is the sole distribution point of line and low-voltage electrical power within the support space 22. The power distribution module 50 may include a plurality of AC power receptacles (typically 6) spaced apart to support multiple power supply connections, a circuit breaker, a surge suppression circuit providing industrial grade surge protection (e.g., to survive 6000V/3000 A surge pulse events, greater than a thousand times), and low-voltage power distribution for various components. The power distribution module 50 may produce a plurality of different low voltages for different devices.
The power distribution module 50 distributes low-voltage power through a distribution circuit to the multichannel amplifier and the signal processor 70. In one embodiment, the distribution circuit includes a ribbon cable connection from the power distribution module 50 to a complementary connector mounted on the support member 20 and electrically connected to the respective connectors associated with the multichannel amplifier and signal processor 70. In another embodiment, the distribution circuit includes one or more printed circuit boards (PCB's) for transferring low voltage power from the power distribution module 50 to the power amplifier 60 and/or to the signal processor 70.
The power distribution module 50 may be operably configured to monitor voltage and/or amperage for each AC power outlet. If an excessive voltage and/or amperage is detected, the power distribution module 50 may be operably configured to shut down one or more individual AC power outlets and/or to cause a notification to be sent to the owner. Optionally, the power distribution module 50 may provide Web-based power management and control of individual AC receptacles. The power distribution module 50 may cause notifications of unusual power supply events to be sent by email in some embodiments.
Signal Processor/Preamplifier
Referring to FIG. 9, the support member 20 may further support an AV processor/preamplifier 70 within the support space 22 and mounted to the support member 20 by means of removable fasteners such as machine screws. In this embodiment, the signal processor 70 receives power through a distribution circuit interconnecting the power distribution module 50 and the signal processor 70. The distribution circuit may include a ribbon cable connected from the signal processor 70 to a suitable connector mounted on the support member 20 and interconnected to a connector associated with the power distribution module 50. The signal processor 70 may also provide signals to the power amplifier 60 and/or the power distribution module 50.
An alternative embodiment of the signal processor 70 shown in FIG. 33. In this embodiment, the signal processor 70s shown from a rear perspective viewpoint which illustrates that the rear side of the signal processor 70 includes a pair of hangers operatively configured to align the signal processor 70 when it is mounted on the support member 20 such that a plurality of ports are connectors disposed on the bottom portion of the signal processor 70, or precisely aligned with corresponding connectors and ports on the distribution circuit to thereby interconnect the signal processor 70 with all necessary signal and power lines.
Referring to FIG. 33, in this illustrative embodiment, the signal processor 70 includes a plurality of network ports as shown generally at 700 (e.g., one Ethernet input, and five Ethernet outputs, which may be connected to Ethernet switching circuitry), a plurality of digital AV ports as shown generally at 702 (e.g., one HDMI output port and six HDMI input ports, which can be redirected to the HDMI output port, with or without processing), a plurality of analogue audio ports as shown generally at 704 (e.g., analogue audio jacks for two input stereo channels and one output stereo channel), a set of digital audio inputs and outputs as shown generally at 706 (e.g., optical/toslink digital audio connection ports such as S/PDIF), a plurality of microphone input channels as shown generally at 708, and miscellaneous control inputs and outputs including an RS-232 port and optionally a remote control port. The ports may also include a reset switch for resetting the signal processor 70 or another component of the system.
The signal processor 70 may include one or more of the following functions:

    
    
        A compact form factor allows placement within the support member 20;
        supports audio configurations for Monaural, 2 channel & 2.1 channel stereo, 3.1 channel and 5.1/7.1 and larger surround configurations;
        audio processing/decoding features may include support for Dolby/DTS/THX and/or other formats;
        Multiple HDMI inputs (e.g., HDMI 1.4, DHCP 2.0 compliant);
        A plurality of analog audio and/or video inputs and outputs;
        pre-amplification circuit is applied to any AV signals which do not have a suitable level for input to the multichannel amplifier;
        IR/Serial and IP control of all functions may be provided for integration with external control systems;
        Full Web-based set-up and control including saving and cloning of configurations may be provided; and
        Managed Ethernet switch may be provided in the signal processor 70.
    
    


The signal processor 70 may include integral pathways for routing and distribution of speaker level signals to loudspeakers which are not immediately proximate the multichannel amplifier. For example, the signal processor 70 may receive speaker level signals from the multichannel amplifier via the distribution circuit, and may route these signals to a subwoofer and/or to surround speakers located external to the support space 22. In one embodiment, the subwoofer may be located at the top of the support member 20.
Multi-Channel Power Amplifier
Referring to FIG. 10, the support member 20 may further support a multichannel power amplifier 60 in the support space 22. In this embodiment, the power amplifier 60 delivers a combination of audio quality, output power, efficiency and reliability to ensure an impressive entertainment experience.
As shown in FIG. 10, the power amplifier 60 may have a compact elongate form factor allowing placement of the amplifier in a narrow space adjacent a plurality of loudspeakers. In contrast to some other AV receiver devices, which provide power amplification circuitry adjacent to a plurality of AV input/output ports and/or signal processing circuitry, the present embodiment separates the input and processing of AV device signals into a signal stage (carried out in the signal processor 70) and a power amplification stage (carried out in the power amplifier 60), which are spaced apart and communicate with each other over a distribution circuit including a signal backplane. Because all of the bulky AV input/output ports and most, if not all, of the electronic hardware associated with AV signal processing is located in the signal processor 70 and not the spaced apart power amplifier 60, it is possible to avoid making the power stage bulky. By separating out the signal stage from the power stage in this way, it is possible to fit the power amplifier 60 into a relatively thin, elongate form factor as shown. In some embodiments, the power amplifier 60 may include hardware for digital signal processing relating to speaker-related cross-over calculations and frequency equalization, which does not add much bulk.
Thus, the power amplifier 60 can provide a high total power output for its size at a low power consumption and low operating temperatures. The power amplifier 60 may have a modular design operably configured to allow different number of output channels to be configured on a per system basis. In some embodiments, all power, audio, control and speaker level signals of the power amplifier 60 are connected via the distribution circuit, which may include an integrated signal and power bus. For example, the power amplifier 60 may include a connector operable to interface with a complementary connector on the support member 20 and connected via the distribution circuit to the power distribution module 50, the signal processor 70, and a plurality of loudspeakers.
LCR Loudspeakers 80
The system 10 further includes a plurality of loudspeakers supported by the support member 20 in the support space 22. Referring to FIG. 11, in some embodiments, the system 10 includes left, center and right loudspeakers 82, 84, 86 (i.e., LCR speakers 80) which may be located at respective left, center and right positions in the support space 22. For example, the speakers 80 may be mounted in a horizontal configuration towards a bottom side of the support member 20. In one embodiment, the LCR loudspeakers 80 include speakers each having a slot. The LCR loudspeakers 80 are positioned and oriented to direct sound waves toward a viewer generally located in front of the display device 40.
The LCR loudspeakers 80 will remain completely concealed behind a support space cover 100 when the system 10 is fully installed and in operation. In embodiments where the cover 100 includes a fabric transparent to audio waves (i.e., an acoustically-transparent fabric), the audio from the LCR loudspeakers 80 will pass through the cover 100 just below the display device 40 with a minimum of interference. The LCR loudspeakers 80 may include an integral connector designed to mate with a complementary connector located on a rear surface of the support member 20. The connections provided through the respective connectors provide speaker level audio to each of the LCR loudspeakers 80. The LCR loudspeakers 80 may also include a positioning system operatively configured to ensure that, when the LCR loudspeakers 80 are being inserted, the connectors on the speaker and on the support member 20 are precisely aligned to ensure a correct and positive connection. This arrangement removes the requirement for a more standard “wired” connection between the power amplifier 60 and the LCR loudspeakers 80 and furthermore, reduces the possibility of the loudspeakers being wired incorrectly. Suitable complementary connectors for making such a connection between the loudspeakers and the distribution circuit may include SamtecTM MPT and MPS series header/socket connectors.
FIG. 28 is a top sectional view of a plurality of receptacles (shown as 282, 284, 286 in corresponding portions of FIG. 4) of the support member 20 in the process of receiving left, right and center speaker enclosures 82, 84, 86, respectively, into a mounted position, and FIG. 29 is an enlarged partial front sectional view of one of the receptacles and showing an audio connector at the rear of the receptacle. FIGS. 28 and 29 together illustrate a self-alignment mechanism whereby movement of the enclosures into the receptacles along a first axis, causes automatic alignment along a second axis with an audio signal connector at the rear of the receptacle in response to deflection from two spaced apart guide members. The guide members each include a locking surface for engaging a complementary locking surface on the enclosures to lock the speakers against movement along a third axis, the first, second and third axes being mutually orthogonal.
FIG. 32 shows an alternative embodiment in which the left and right speakers 82, 84 have been moved horizontally such that they no longer abut the center speaker 84. In this embodiment, better stereo separation is achieved by horizontally placing the left and right speakers 82, 84 to the left and right of the display device 40, respectively, as viewed from a direct viewing position. As above, the loudspeakers are embedded in the wall and are covered by a wall opening cover 100 disposed in a plane rearward of the plane of the display device 40.
Subwoofer Loudspeaker
The system 10 may include a compact, positionable subwoofer loudspeaker located within the wall space. Referring to FIG. 12, a subwoofer loudspeaker according to one embodiment is shown being supported by the support member 20 in a portion of the support space 22 located directly above the support member 20. The subwoofer loudspeaker includes a subwoofer enclosure and one or more physical subwoofer drivers.
In embodiments such as the one shown in FIG. 12, the physical subwoofer drivers are mounted entirely within the subwoofer enclosure and are not exposed or visible on any exterior surface. This configuration causes all of the subwoofer sound to exit the enclosure through a narrow horizontal opening, which may be located along the lower edge of the enclosure or on another face of the enclosure. The subwoofer opening may be positioned proximate to an edge of the display device 40. The precise position of the opening in the face of the enclosure may be customized for each installation based on the relative sizes of the display device 40 and/or the cover 100. In the embodiment shown in FIG. 12, the enclosure is to be positioned at a position above and adjacent to a top edge of the display device 40. This allows the subwoofer audio to pass through the cover 100 just above the display device 40 with no visible sign of where the sound is coming from.
In alternative embodiments, the subwoofer drivers may be visible on an exterior surface of the enclosure. In such cases, the openings of the subwoofer drivers may be positioned in a clear line of sight to the viewer to avoid the sound waves having to traverse around the display device 40. In some embodiments, the openings of the subwoofer drivers may have a partially clear line of sight to the viewer. Despite the clear or partially clear line of sight of the subwoofers to the viewer, the viewer will be unable to view the subwoofer loudspeaker in this embodiment once the system 10 is fully installed, since the subwoofers will be concealed by a cover 100. In still other embodiments, the subwoofer may be placed behind the display device 40, but within the wall space.
As shown in FIG. 12, the subwoofer enclosure may be removably received in a channel formed by first and second opposite guides, for example, first and second sides of the mounting bracket. The guides may include a plurality of affixing points at different positions, for example, a plurality of openings through which at least one fastener may be inserted through the guide into the subwoofer enclosure to affix it in a particular position. Thus, the subwoofer enclosure may be positionable and removably mounted at any one of a plurality of positions within the guides in order to position an opening of the subwoofer enclosure in a line of sight to the viewer to reduce obstruction of the sound by the display device 40. In FIGS. 5 and 12, the subwoofer is vertically positionable. Alternatively, or in addition, the subwoofer may be horizontally positionable in some embodiments.
Equipment Mounting Member
The system 10 may further include an equipment mounting member 150 affixed to or integral with the support member 20. Referring to FIG. 13, an equipment mounting member 150 according to one embodiment is shown affixed inside the support member 20 and securely mounted thereto using fasteners such as machine screws. The equipment mounting member 150 is operably configured to removably mount various AV signal source devices that will be held in the support space 22. Different AV source will be mounted to the equipment mounting member 150 depending on user-desired installation features and functionality. Examples of common AV signal source devices include cable TV set-top boxes, satellite receivers, AppleTV® devices, steaming media players, small form factor personal computers and other similar AV source components. The equipment mounting member 150 can optionally also provide a mounting surface and location for balun-based systems (active and/or passive) used to extend AV signals (including HDMI) from remotely located AV source devices such as DVD, CD and/or Blu-Ray Disc players located externally to the support space 22. Data communication, computing and networking equipment (e.g., Internet routers or modems), may also be removably mounted on the equipment mounting member 150 in the support space 22. For example, in the exemplary embodiment shown in FIG. 19, the mounted devices include dual GefenTM HDMI extenders (fiber), a GefenTM HDMI extender (CAT-6), an RTITM XP-6 Controller (i.e., a remote control processor operable to communicate with a remote control and to control the AV system in response to user commands), an AppleTVTTM device, an Apple Mac MiniTM, and a MotorolaTM high definition personal video recorder (PVR).
In this embodiment, the equipment mounting member 150 is removable and is operably configured to removably mount both universal and device-specific mounting brackets for use in mounting the devices such as those described above. The equipment mounting member 150 may include a plurality of integrated affixing points (e.g., a plurality of spaced-apart openings or clips) for mounting the brackets and/or for managing wiring. Advantageously, any equipment that is mounted on the equipment mounting member 150 is located proximate the display device 40 and thus can easily be configured to communicate with the display device 40 (whether by wired or wireless connection), but it does not occupy any space in the room. Also, equipment in the in-wall space 18 is not visible to a viewer of the display device 40 because a view of these components is obstructed by the display device 40 and/or the wall opening cover 100 when mounted.
Wall Surface Interface Member
The system 10 may include a wall surface interface member 106 operably configured to provide an interface for a finished wall surface that is to be installed around the wall opening. In other words, the wall surface interface member 106 serves to define the periphery, and thus the overall footprint, of the mounting apparatus 12 in the wall. Referring to FIG. 14, one embodiment of a wall interface is shown at 106. The wall surface interface is operably configured to provide an attractive, permanent, fixed and continuous border defining the external physical dimensions of the system 10 on the finished wall surface. This border serves as a transition point, or “interface,” between the mounting apparatus 12 and the material used as the final wall surface, most typically, but not exclusively, gypsum wallboard (G.W.B.) or drywall. In this embodiment, the wall surface interface includes a metal lip at a peripheral edge of the interface to provide a solid and robust surface for the final wall surface to run up to and abut.
In some embodiments, at least part of the interface may be provided by a peripheral portion of the support member 20, for example, by specially formed edges of the box-shaped frame of the support member 20. In some embodiments, the wall surface interface may include integral mounting points, such as threaded or unthreaded affixing points, for the display mounting member 30 and/or the wall opening cover 100. In some embodiments, the wall surface interface may be part of the support member 20, or alternatively, it may be a separate piece removably mounted to the support member 20 as part of the mounting apparatus 12. In one embodiment, the wall surface interface may be affixed to a front surface of the support member 20 by the use of fasteners such as machine screws.
The wall surface interface may be positionally adjustable in at least one dimension. For example, the interface may be vertically adjustable to support forming a wall opening of various sizes in the vertical dimension to allow for proper positioning of the height of the apparatus 12/wall boundary (i.e., the point at which mounting apparatus 12 ends and the finished wall surface begins) for a particular size of display device 40 and wall opening cover 100 used in a given installation. In some embodiments, the interface instead may be adjustable in a horizontal direction to adjust the horizontal width of a final wall opening that will be formed around the installation. In still other embodiments, the interface member 106 may be adjustable in both a horizontal and a vertical direction, such that the footprint of the wall opening in the finished wall surface is adjusted in both the horizontal and vertical dimensions by moving the interface member.
In this embodiment, the wall surface interface includes openings configured to align with the horizontal openings in the subwoofer. The wall surface interface member 106 includes at least one interface opening configured to align with an inner opening in the wall opening cover 100, to provide an unimpeded output path for sound waves emanating from the in-wall subwoofer. At least a portion of the display mounting member 30 may extend through the opening to facilitate mounting the display device 40 externally.
Protective Cover
Referring to FIG. 20, a protective cover system 200 may be provided in accordance with one embodiment, to provide temporary physical protection to the interior of the support member 20 prior to the final installation of all internal components. Once the surrounding wall surface has been repaired, mudded, sanded, and painted, as needed, the cover system may be removed. The cover system may simply use a different size single-piece cover for differently sized installations. Alternatively, the protective cover system 200 may be provided as a two piece system operably configured to protect the system for a range of different size wall openings. The protective cover system includes an upper cover 202 configured to protect the top part of the support member 20 and support space 22, and a lower cover 204 configured to protect the bottom part of the support member 20 and support space 22. The upper and lower covers 202, 204 can be slid apart in a vertical direction to either expand or contract the overall footprint of the protected area. FIG. 20 illustrates that the upper cover can be slid up and down relative to the lower cover, and the relative positions of the two covers can be fixed by tightening a screw. The entire cover is then mounted using further screw holes to the wall surface interface member 106.
Display Mounting Member
The system 10 and apparatus 12 include a display mounting member 30 operably configured to facilitate mounting of a display device 40 (e.g., TV) to the support member 20, and hence, to the wall support. One embodiment of the display mounting member 30 is shown in FIG. 15. In this embodiment, the display mounting member 30 may be affixed to the wall surface interface using fasteners such as machine screws. The display mounting member 30 may include a metal bracket operably configured to support the display device 40. The display mounting member 30 is operably configured to support the display device 40 in a display mounting position located outside of the wall and in front of the support member 20 such that the display device 40 is spaced apart from the wall, spaced apart from the wall opening cover 100, and located in a plane that is substantially parallel to both the wall and the wall opening cover 100.
The display mounting member 30 is operably configured to allow vertical and horizontal adjustment of position such that the final position of the display device 40 mounted to the display mounting member 30 can be adjusted both vertically and horizontally, thus allowing precise placement (e.g., centering) of the display device 40 in front of the wall opening cover 100. In one embodiment, the display mounting member 30 includes a first plurality of openings aligned to correspond with a corresponding second plurality of mounting openings in a display mounting member 30 interface portion of the support member 20. One of more fasteners may be inserted through the first and second plurality of openings to prevent relative movement between them display mounting member 30 and the display mounting member 30 interface portion, once the display mounting member 30 has been moved into a desired position. In the embodiment shown in FIG. 15, the display mounting member 30 includes a display mounting bracket having a plurality of openings operably configured to correspond to a corresponding plurality of mounting slots in the wall surface interface, which is integral with or removably mounted to the support member 20.
In this embodiment, the bracket has a very shallow profile thereby allowing the display device 40 to sit nearly flush with the wall opening cover 100. The display mounting member 30 may include at least one cable management opening and affixing points to ensure that cabling from within the support space 22 can be run to the display device 40 in a concealed fashion. The display mounting member 30 may include at least one ventilation opening operably configured to improve air circulation within the support space 22 to support passive cooling of the internal components within the support space 22. In some embodiments, the display mounting member 30 is operable to leave as open more than half of the area in a vertical plane to facilitate cable management and cooling.
Display Mounting Hangers
The system 10 may include vertical hanger members 32, 34 designed to be affixed directly to the display device 40 (TV) by hanging and operably configured to cooperate with the display mounting member 30, to support the display in front of the support member 20 and the wall opening cover 100 (see FIG. 22). The hangers 32, 34 include dedicated slots operably configured to mate with the display mounting member 30 to provide a strong, secure mounting assembly to support the display device 40. The vertical hangers 32, 34 may include integral holes and/or slots to allow vertical adjustment when affixed to the display (TV).
FIG. 31 illustrates an embodiment of a display mounting member 30 operably configured to support an articulation mechanism 36 comprising a plurality of hinged arms 38 interconnecting the display device 40 with the wall 14. In this embodiment, the display device 40 may be moved slightly outwardly from the wall and may be tilted horizontally or vertically to provide better viewing from the side. The extent to which the display is pulled out from the wall has been greatly exaggerated in this figure simply in order to fully illustrate the hinged arms.
Wall Opening Cover
Referring to FIG. 16, the mounting apparatus 12 includes a wall opening cover 100. In the embodiment shown in FIG. 16, the cover 100 is installed directly in front of the support member 20. The cover 100 is operably configured to hide from view the internal components located within the support space 22 located within the wall, and provide an aesthetically appealing and customizable design element as part of the overall system. In some embodiments, a design professional may wish to select an acoustically transparent fabric for the cover 100 that best matches the interior décor of the room in which the system 10 will be located.
Alternatively, in some embodiments where a fabric cover 100 is not desired or appropriate, the cover 100 may be formed of the solid material to have a solid surface. In such embodiments, the cover 100 may include at least one slot aperture or a plurality of unobtrusive openings in the cover 100 to allow sound to emanate from loudspeakers placed within the wall, for example, to exit from LCR and subwoofer loudspeakers in the in-wall space.
The cover 100 may be removably affixed to the wall surface interface member 106 or to the support member 20 by any one of a variety of methods, or by a combination of methods. In one embodiment, the cover 100 is affixed using powerful magnets. This contributes to a very clean and appealing appearance of the finished installation. In some embodiments, the wall opening cover 100 may be supported by the support member 20 installed in the wall. In other embodiments, the wall opening cover 100 may be supported in its installed position by the wall surface itself. For example, as shown in FIG. 34, the cover 100 may include a connector on its rear surface, and a portion of the wall surface intended to remain underneath the cover 100 during use may include a complementary connector. In FIG. 34, the connector includes a compact Z-clip 107, 109. Other ways of attaching the cover 100 to the wall surface include a removable light adhesive placed between the cover 100 and the wall surface 104, or a hook and loop fastener set such as VelcroTM. Alternatively, the cover 100 may be attached by a combination of methods. In the embodiment shown in FIG. 23, the top portion of the cover 100 is affixed to the wall surface interface member by hanging using a French cleat 300, 302, whereas the bottom portion of the cover 100 is affixed by magnets configured to match to threaded, adjustable-depth metal spacers of the support member 20, as shown at 304, 306. The French cleat includes first and second matching connecting pieces mounted on the cover and the wall interface member, respectively, whereing the first and second connecting pieces have complementary beveled edges configured to mate with each other to facilitate hanging the cover on the wall interface member. It will be appreciated that the position of the cover on the wall will depend on the position of the wall interface member, which in turn, will depends on the size of the display device 40 that is intended to be used. In other words, the wall interface member is movable to provide a suitably sized finished wall opening for a given size of display device 40. Because of the manner in which the wall opening cover is mounted to the wall surface interface member, the bottom edge of the finished wall surface will generally align with an upper edge of the cover 100. The wall opening cover 100 will thus be inherently repositioned to cover the final wall opening for any size installation.
Once installed, there remains no visible means of attachment for the cover 100. FIG. 27 shows a top cross-sectional view of the display device 40 and the wall opening cover 100, as they serve to obstruct the view of the inner-wall space within which the remainder of the components of the system 10 are mounted. In one embodiment, the cover 100 becomes gradually thicker in cross-sectional area as it moves from a peripheral edge of the cover to an inner portion of the cover, having a maximum thickness of about 5⁄8 of an inch. In this embodiment, there is a further approximately 1⁄8′′ clearance between the thickest portion of the cover and a rear surface of the display device 40. In this embodiment, the inner opening of the cover is about 29-31 inches wide by about 18-20 inches high, however, other dimensions for the inner opening may also work. The outer periphery of the cover 100 can be of different sizes depending on the size of the display device 40 that will be used in the installation. In some embodiments, the cover 100 may extend about 5 inches beyond the outer periphery of the display device 40, or in other embodiments, between about 2 inches to 8 inches beyond the outer periphery of the display device 40.
In most embodiments, the inner opening in the cover 100 will be dimensioned to be substantially smaller than the display device 40. This means that at least a portion of the cover overlaps with a peripheral portion of the display device 40 if viewed from a front position directly in front of the display device 40. In other words, a projection of the display device 40 onto the plane of the cover will overlap somewhat with an inner, overlapping portion of the cover. The overlapping portion obstructs a viewer's view of the in-wall support space 22 behind the overlapping portion, even if the display device 40 is not mounted. This is not particularly useful from a direct frontal viewing position since, once the display device 40 is mounted, the aforesaid portions of the in-wall support space 22 are not visible to the viewer, because the display device 40 obstructs a clear line of sight to them (whether or not a cover is mounted behind the display device 40). However, because the cover and the display device 40 are located in different, albeit generally parallel planes, the overlapping portion of the cover is useful in obstructing a viewer's view of the in-wall space 18 at an extreme angle of view. For example, FIG. 25 illustrates a perspective side view of a completed AV system 10 installation from one extreme angle that is unsuitable for use as a viewing position for the display. Notwithstanding the extreme angle of this viewpoint, the in-wall space 18 is not visible to the viewer. This is because, even though the cover is mounted in a plane which is spaced apart from the plane in which the display is mounted, the overlapping portion of the cover, as defined above, serves to obstruct the viewer's view into the in-wall space, even where no portion of the display device 40 is able to obstruct the view at this angle. Furthermore, it will be appreciated that the front of a display device 40 may be a different size than the rear of the display device 40. Indeed, the rear of the display device 40 may be smaller in overall area than the front of the display device 40. Accordingly, the dimensions of the cover's overlapping portion are chosen based on the size of the rear portion of the display device 40 and the distance by which it is spaced apart from the wall. If the rear portion of the display device 40 is relatively smaller and/or it is spaced relatively further from the wall, a larger overlapping portion is used to ensure that the cover is effective in concealing the in-wall space. If the rear portion of the display device 40 is relatively smaller and/or it is spaced relatively closer to the wall, the overlapping portion may be smaller. Configuring the cover in this manner preserves the benefits of mounting the display device 40 spaced apart slightly from the wall (e.g., the display device 40 is better able to dissipate heat, avoiding the kinds of thermal problems that could arise if it was embedded into the wall), but not at the cost of allowing a viewer to see into the in-wall space, which would be unsightly.
In many typical embodiments, the cover 100 will be symmetrical with respect to the horizontal and vertical axes of the display device 40, for example, the cover may extend past the periphery of the display device 40 on all sides of the display device 40 to effectively “frame” the entire display device 40 in a symmetrical manner, as viewed from a frontal viewing position. In some embodiments, the cover will be symmetrical only with respect to one of the horizontal and vertical axes of the display device 40. For example, if the cover is non-rectangular (e.g., the cover is a symmetrical trapezoid), it may be viewed as symmetrical with respect to the horizontal axis of the display device 40 but not with respect to its vertical axis. In still other embodiments, the cover will be asymmetrical with respect to the display device 40, as viewed from a frontal viewing position.
In part, the shape of the final wall opening, and thus the shape of the cover, may differ depending on the composition of the speakers in a particular system installation. For example, in one embodiment, the installation may have left and right speakers 82, 84 as shown in FIG. 32 but no subwoofer 180 or center speaker. In such an embodiment, the in-wall space 18 of the system 10 may be configured to only extend past the display device 40 on the left and right sides, but not below or above the display device 40. In this case, the cover may be suitably dimensioned to only extend to the left and right of the display device 40, but not necessarily above and below it (as viewed from a front view). If the preceding embodiment is modified by adding a subwoofer positioned as shown in FIG. 32 (but still omitting the center speaker), it may be appropriate to provide a cover which takes the shape of an inverted “U”. In another embodiment which has only the LCR speakers as shown, for example, in FIG. 19, but no subwoofer, the cover may be be installed asymmetrically, being configured to only extend below the display device 40 but not extend to the left, right, or above the display device 40. Other cover shapes may be used for aesthetic purposes, even where they are unnecessary to permit sound waves from an underlying in-wall speaker to pass through.
FIG. 30A illustrates an alternative embodiment of the cover in which the cover is slightly recessed into the wall such that it is flush with the finished wall surface. FIG. 30B illustrates an alternative embodiment in which the cover is not a unitary piece, but rather, is formed from four pieces which attach together along the diagonal lines emanating from each corner to the corresponding corners of the inner opening of this embodiment of the cover.
Methods of Installation
In view of the above description of various embodiments of the invention, the following summary provides an exemplary embodiment of an installation method of the AV system 10 and mounting apparatus 12 of the invention. In some cases, the mounting apparatus 12 (including the support member 20 and accessories thereto), may be provided in the form of a kit to the installer.
1. For retrofit installations (as opposed to new construction installations), remove the wall surface material (typically drywall) from the portion of the wall where the system 10 will be installed.
2. Create a framed window-style opening within the wall framing members that measures about 48′′ high by 48′′ wide. (A different size opening can be used for a different embodiment, depending on the mounting apparatus 12 that is being used and the size of the display device 40 that will be installed.) In some cases, install at least one additional wall support reinforcement member 26, such as one or more 2′′×4′′ wood pieces attached in parallel to the original wooden wall studs 16, prior to installation of the mounting apparatus 12 in the wall. Ensure that all sides are square and plumb.
3. Place a support member 20 of the mounting apparatus 12 into the framed opening and position it such that it is resting on a lower horizontal cross member of the framed opening, and that the back surface of a front flange of the support member 20 is resting against the front face of the wall framing members.
4. Securely affix the support member 20 to the wall framing using the appropriate fasteners (e.g., wood or metal screws) through the sides of the support member 20 in the holes provided.
5. Optionally, install at least one temporary reinforcement member across the support member 20 to stiffen the support member 20 while it is being installed. Next, position the subwoofer mount (e.g., a subwoofer bracket), while leaving the temporary reinforcement member installed, in the space above the support member 20.
6. Using the supplied fasteners (e.g., machine screws), affix the subwoofer mount to the support member 20.
7. Next, affix the top flanges of the subwoofer mount to the horizontal framing member at the top of the 48′′ by 48′′ framed opening and ensure that any temporary alignment clips used are flush with the face of the framing. This will ensure that the subwoofer mount is positioned in the exact centre of the framed opening which is important to the correct positioning of the subwoofer during final installation.
8. Next, remove the temporary reinforcement members and the alignment clips.
9. If the wall surface interface member is not part of the support member 20, install the wall surface interface member to the support member 20. Adjust and set the wall surface interface member at the desired height as specified for the size of display device 40 (e.g., television) being used.
10. Install the line voltage connection member 120 and make the electrical connection that feeds electrical power to the line voltage connection member. Install the protective cover on the line voltage connection member.
11. Install the low voltage connection member 130 and make all low voltage cabling connections. Install the protective cover on the low voltage connection member.
12. Install a protective cover system, including an upper protective cover and a lower protective cover, onto the face of the support member 20, to protect the inside of the support area from construction debris. Secure both covers using the supplied fasteners.
13. Apply the final wall surface (typically drywall) to the wall framing. Ensure that the wall surface extends up to and directly abuts all four sides of the support member 20 (or to the wall surface interface member), but does not directly cover the support member 20. Apply any final finish materials to the wall surface (e.g., paint or wall paper).
14. Once the final wall finishing is complete, remove the protective cover system.
15. Install the subwoofer enclosure into the upper portion of the support member 20. Use the locating/centering pins 198, 199 that extend slightly from the subwoofer mount to align with the corresponding guide slots 186 in the side panels of the subwoofer enclosure as you press the enclosure upward into position above the support member 20. Securely affix the subwoofer enclosure using the four fasteners (e.g., machine screws) provided. Using the supplied cable, connect the input of the subwoofer to the corresponding subwoofer output connector located within the top portion of the signal processor 70, once the signal processor 70 has been installed.
16. Install the power distribution module 50 on the left side of the support member 20 using the two positioning guide slots provided 251, 252. Once in position, lower the power distribution module 50 such that it is seated firmly in the support member 20 and the connections at the bottom of the power distribution module 50 are mated to the corresponding connections on the power and signal distribution circuit or backplane. Install suitable fasteners (e.g., two machine screws) to affix the power distribution module 50 in place to the support member 20. Connect the male locking power connector on the power distribution module 50 to the corresponding female power receptacle on the line voltage connection member and twist to lock the connectors.
17. Install the multi-channel power amplifier 60 in the lower centre portion of the support member 20. The multi-channel power amplifier 60 will rest on the horizontal shelf that runs the full width of the support member 20. Once in position, slide the multi-channel power amplifier 60 back such that it is seated firmly in the support member 20 and each of the connections on the back side of the multi-channel power amplifier 60 are mated to the corresponding connections on the distribution circuit.
18. Install the AV signal processor 70 on the right side of the support member 20 using the two positioning slots provided 271, 272 (corresponding to the hangers 281, 282 in FIG. 33). Once in position, lower the signal processor 70 such that it is seated firmly in the support member 20 and the connections at the bottom of the signal processor 70 are mated to the corresponding connections on the distribution circuit. Install the appropriate fasteners (e.g., two machine screws) to affix the signal processor 70 in place.
19. Install the left, center and right loudspeakers (center channel speaker may be optional) in the lower horizontal cavity of the support member 20. The lower horizontal cavity may be configured as a loudspeaker receptacle operably configured to removably receive one or more loudspeaker enclosures. Slide each loudspeaker enclosure back such that it is seated firmly within the support member 20 and the connections on the back side of the loudspeakers are mated to the corresponding connections on the distribution circuit. In some embodiments, a plurality of loudspeakers, e.g., all of the LCR loudspeakers 80, may be combined in a single integrated enclosure, rather than having their own separate enclosures. In such embodiments, the single integrated enclosure is installed and removably received into the corresponding loudspeaker receptacle on the support member 20.
20. If this installation includes surround speakers, connect the speaker wire from each of the installed surround speakers to the corresponding surround speaker terminals located within the top portion of the signal processor 70.
21. Install the equipment mounting panel into the support member 20 using the supplied fasteners.
22. Install and affix the supplied mounting brackets for any required internal AV signal source, computing, communication and/or control equipment onto the face of the equipment mounting panel such that it is securely held in the support space 22.
23. Make all electrical and low voltage connections between the power distribution module 50, the signal processor 70, the AV signal, communication, and control equipment and secure all wiring to the equipment mounting panel.
24. Install the display mounting member 30 using the supplied machine screws.
25. Install the wall opening cover using the supplied hardware and adjust its position relative to the wall surface, so that the wall opening cover is flat and flush against the wall surface. For example, in one embodiment, you might affix the cover by hanging the cover using a French cleat at the top of the cover and affix the bottom of the cover by attaching magnets on the bottom of the cover to adjustable-depth magnetic stops/spacers on the support member 20.
26. Install the two display mounting member 30 hangers onto the back of the flat panel display device 40.
27. Make the power connection between the flat panel display device 40 and the power distribution module 50.
28. Make all low voltage cabling connections between the flat panel display device 40 and the signal processor 70.
29. Install the flat panel display device 40 onto the display mounting member 30, such that the display device 40 is suspended on the wall in front of the wall opening cover, and spaced apart from the finished wall surface.
It will be appreciated that some of the above steps may be omitted, substituted, performed in parallel, or performed in a different order, as appropriate, depending on the specific requirements of the AV system 10 installation at issue and the features of the specific embodiment of the apparatus 12 being used to install the system 10.
Completed Installation
FIGS. 24 and 25 provide perspective front and side views of an AV system 10 installation in a wall upon completion, according to one embodiment. In this embodiment, system 10 installation is complete when the display device 40 or TV has been mounted to the display mounting member 30 such that the display device 40 or TV is suspended in front and spaced apart from the wall opening cover. Although the finished installation in this embodiment includes a high-definition display device 40, a mounting system, high performance loudspeakers, multichannel power amplification, AV signal processing/switching and distribution, a plurality of high definition AV signal sources, audio processing and decoding for Dolby and DTS surround formats, and power distribution and surge protection for all components, all that is visible in the completed installation is the display device 40 and the wall opening cover employed to visually “frame” the display device 40 for an aesthetically pleasing and ultra-low profile finished installation.
While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims. It should also be appreciated that the embodiments disclosed herein are not mutually exclusive such that features of one embodiment may be combined with those of another embodiment to form further embodiments falling within the scope of these claims. Similarly, it should be appreciated that various other possible combinations and permutations of the internal and external components described herein may form still further embodiments falling within the scope of these claims. Furthermore, in other embodiments of the invention, some components described above as removably mountable may instead be integral or permanently mounted, whereas some components described as integral or as permanently mounted, may instead be made to be removably mountable.
