Various embodiments of the invention pertain to speaker mountings and assemblies that allow relatively easy installation.
In order to save space and/or for aesthetic reasons it is often desirable to mount speakers within a wall or ceiling cavity or recess. A mounting assembly is commonly used to secure the speakers to the wall or ceiling. Various types of frames and fasteners are often used for the purpose of securing the speaker to the wall or ceiling cavities.
A speaker mounted in a wall or ceiling using a conventional frame assembly typically has a sound dispersion axis that is perpendicular to the plane formed by the mounting surface, e.g., wall or ceiling. However, speakers with sound dispersion axes directed at the floor or an opposing wall often do not provide an environment with optimum sound quality. Thus, when installing one or more speakers in a room, it is often desirable to adjust the angle of one or more of the speakers to provide a better sound quality or effect.
It is often necessary or desirable to adjust the direction in which, for instance, a ceiling-mounted speaker radiates sound. For example, when providing a surround sound effect with one or more recessed speakers, the sound dispersion axis of the speakers is adjusted to provide optimum sound quality at a given point or location in the room.
However, conventional speaker mounting systems make it difficult to adjust the sound dispersion axis of a speaker to provide an optimum sound quality. For example, many conventional speakers are fixedly mounted in a wall or ceiling recess and cannot be adjusted. Additionally, even when adjustments to the speakers are possible, prior art mounting mechanisms are typically restricted to a limited number of positions. This may not always permit directing a speaker's sound dispersion axis to obtain the best sound quality in a particular room or environment.
Even when the speakers can be adjusted, they are often difficult and/or cumbersome to readjust at a later time. This may be necessary, for instance, in a surround sound speaker configuration that has been setup for optimal sound quality at a first location and now the optimal sound quality is desired at a second location. Such is the case, for example, when a couch is moved from a first location to a second location in a room. Readjusting conventional speakers is typically requires removal and reinstallation of the speaker and/or speaker mounting assembly which is undesirable and costly.
Audio devices, such as speakers, woofers and/or tweeters, are often mounted within a wall or ceiling cavity or recess. Various types of frames and/or fasteners are used for the purpose of securing the audio devices within a wall or ceiling cavity.
Mounting such audio devices within a recessed cavity poses several problems. For instance, mounting an audio device inside a ceiling cavity may prevent the sound emitted from such device from directly reaching listeners. Adjusting a conventional mounting mechanism to position the audio device at the correct depth, direction, and angle may be burdensome or impossible. That is, it may not be possible to direct the sound dispersion axis of the recessed audio device to reach a listener directly. As a result sound quality may be affected.
When mounting a tweeter, for instance, the tweeter is typically fixedly secured in a mounting base. The mounting base may then be secured to a supporting mechanism within a ceiling cavity, for instance. However, conventional mounting mechanisms do not permit to easily adjust the position (e.g., depth, direction, and angle) of the tweeter.
Additionally, conventional mounting systems and fasteners are typically cumbersome and time-consuming to install, take many steps to mount, and require the use of several tools. This increases the cost of installation and deployment of, for instance, recessed speakers, lights, or exhaust fans.
In the following description numerous specific details are set forth in order to provide a thorough understanding of the invention. However, one skilled in the art would recognize that the invention may be practiced without these specific details. In other instances, well known methods, procedures, and/or components have not been described in detail so as not to unnecessarily obscure aspects of the invention.
The following description, certain terminology is used to describe certain features of one or more embodiments of the invention. The term “audio device” refers to any type of sound-generating device, including a speaker, loudspeaker, audio speaker, woofer, subwoofer, tweeter, and/or acoustic transducer.
A first aspect of the invention provides a recessed speaker assembly that can be mounted within a cavity and coupled to a mounting substrate by manually turning a single Dog Actuator Ring that causes a plurality of Rotating Dogs to rotate and secure the recessed speaker assembly. The advantage of this recessed speaker assembly is that a single turning motion can serve to couple the assembly within a cavity with the need for tools.
A second aspect of the invention relates to a Baffle that is pushed into the recessed speaker assembly to secure the Baffle and an audio transducer (speaker) to the recessed speaker assembly. The Baffle includes a plurality of Latch Assemblies that automatically engage the recessed speaker assembly. Additionally, unique electrical contacts are used so that the audio transducer is electrically coupled to the recessed speaker assembly without having to manually splice and/or attach wires for the audio transducer.
A third aspect of the invention relates to a wire connection device that provides an easy to install, secure and reliable electrical connection. The electrical wires are inserted into a Wire Guide which retains the wires in place. The Wire Guide is then inserted into a Connector Base, causing the ends of the wires to be impaled by a Needle Wire Penetrator that electrically couples the wires to terminals at an opposite end of the wire connector device. Additionally, the wire connector device may include an integrated system to release or inject grease into the connection chamber, to thereby seal the electrical connection from environmental effects.
A fourth aspect of the invention relates
Zero Tool, Thin Wall, Frame Mounting System
In one example, the recessed speaker assembly 100 may comprise a Dog Actuator Ring 102, a Latch Trap Ring 110, a Mounting Frame 104, a plurality of Rotating Dogs 106, a Retaining Ring 108, and Back Can 112. The Mounting Frame 104 may defined as substantially circular ring 124 defining a central opening 114 and having a perimeter flange 116 that serves to rest against the exterior surface of the mounting substrate. The Dog Actuator Ring 102 is inserted within the central opening 114 of the Mounting Frame 104 with the Latch Trap Ring 110 between the Dog Actuator Ring 102 and the Mounting Frame 104. The Retaining Ring 108 may be fixedly attached to the Mounting Frame 104 by fasteners 118. The Back Can 112 may fit over the Retaining Ring 108 to protect a speaker and/or other components housed within the recessed speaker assembly 100.
The attachment system to fasten or couple the recessed speaker assembly 100 to a mounting surface, may be comprised of four major components—the Mounting Frame 104, the Dog Actuator Ring 102, the plurality of Rotating Dogs 106 and the Retaining Ring 108. The Mounting Frame 104 is sized to fit through an opening of the mounting surface while the perimeter flange 116 rests against the exterior surface f the mounting substrate. Note that rather than suing screws (as employed by prior art dogs), the recessed speaker assembly 100 uses a plurality of Dog Guide Pins 120 that center and guide a corresponding Rotating Dog 106 that rotates about the Dog Guide Pins 120. A Dog Tower 122 provides for initial dog placement and rotational constraints.
The interaction between the Dog Actuator Ring 102 and the Rotating Dogs 106 is now described. When in the pre-installation position, the Rotating Dogs 106 are in a “retracted” position that allows the Mounting Frame Assembly to be installed through a precut opening in the mounting substrate. That is, the Rotating Dogs 106 are turned or positioned such that they do not obstruct the circular ring 124 from passing through the opening in the mounting substrate. Once the perimeter flange 116 is pressed against the exterior surface of the mounting substrate, the installer rotates the Dog Actuator Ring 102, assisted by engaging his/her fingers against the Dog Actuator Rotation Assist Flange 126; which in turn causes the simultaneous rotation of the plurality of Rotating Dogs 106 via an array of toothed Dog Actuator Gears 130 molded into the exterior edge of the Dog Actuator Ring 102. This action rotates the plurality of Rotating Dogs 106 into a position approximately ninety (90) degrees from their pre-installation position and positions the Spiral Ramp Engagement Pins 402 (
Simultaneously pressing the Ratchet Release Lever 140 and counter-clockwise rotating the Dog Actuator Ring 102 via finger pressure on the Dog Actuator Rotation Assist Flange 126 allows the ratchet to release (i.e., the Ratchet Engagement Flange 1004 disengages from the Ratchet Teeth 504) and the Dog Actuator Ring 102 to rotate. This action lifts the Rotating Dog 106 back up the Dog Tower 122 channels, disengaging the recessed speaker assembly from the mounting substrate. Fully counter-rotating the Dog Actuator Ring 102 causes the Rotating Dogs 106 to reengage the gear interface (e.g., the Dog Gears 410 engaged to the Dog Actuator Gear 130) between the Rotating Dogs 106 and the Dog Actuator Ring 102 thereby rotating the Rotating Dogs 106 back into their pre-installation position, and enabling the removal of the Mounting Frame 104 from the mounting substrate.
To disengage, the Ratchet Release Lever 140 is manually depressed so that the Ratchet Engagement Flange 1004 disengages from the Ratchet Teeth 504. The Dog Actuator Ring 102 is then rotated in the opposite direction (e.g., counterclockwise), which causes the Dog Actuator Gear 130 to slide within the Spiral Ramp 132 from the second end 910 to the first end 908. Upon reaching the first end 908, the reverse rotation (e.g., counterclockwise) of the Dog Actuator Ring 102 causes the Dog Gears 410 to become engaged to the Dog Actuator Gears 130. This rotation of the Rotating Dog Gears 410 causes the Dog Foot 408 to rotate inward so that the recessed speaker assembly 100 can be removed. In this manner, the recessed speaker assembly 100 (e.g., Mounting Frame 104, Dog Actuator Ring 102, Retaining Ring 108, and Latch Trap Ring 110) can be disengaged (by pressing on the Ratchet Release Lever 140) by a single manual reverse turn or rotation of the Dog Actuator Ring 102, without the need to individually disengage each rotating dog or fastener.
Zero Tool, Linear Snap-Lock Baffle Attachment System
According to yet another feature, a near instantaneous mechanical assembly between a loudspeaker Baffle Assembly and a preinstalled Mounting Baffle Assembly can be achieved while simultaneously making the electrical connections required for the previously installed and wired Mounting Baffle Assembly. No pre-alignment is required other than inserting the Baffle Assembly into the Mounting Frame opening. Any rotational orientation is allowed, and the system makes and maintains an electrical connection regardless of the insertion orientation. The latching system is spring tensioned such that pushing inward slightly unloads the retention latches sufficiently to allow after insertion rotation in those applications that incorporate angled transducers. The spring tensioning system also accommodates tolerance variations ensuring tight mechanical connections. The latching method described is small enough to fit into the space normally allowed between the low frequency transducer and the outer diameter of the Baffle molding, thereby requiring very little, if any, increase in the system's overall diameter.
In one example, recessed speaker assembly 100 may further include a Baffle 1102, a plurality of Latch Assemblies 1104, a Network Printed Circuit Board (PCB) 1106, a plurality of Rotating Contact Assemblies 1108, and a Connector Support Ring 1110. The Connector Support Ring 1110 is coupled by a plurality of ribs 1112 and supported by the Retaining Ring 108. The Connector Support Ring 1110 serves as a support for a Contact PCB 1114 which may provide audio signals or power to the recessed speaker assembly 100. An audio transducer 1120 may be mounted our coupled within the Baffle 1102. The plurality of Latch Assemblies 1104 are coupled to the perimeter of the Baffle 1102 (on the inner side of the Baffle 1102) and serve to couple and engage the Baffle 1102 to the Mounting Frame 104.
When it is desired to remove the Baffle 1102 from the Mounting Frame 104, the Latch's 1404 Latch Foot 1414 is disengaged by lifting the Lever 1416 to turn the Spiraling Wedge 1418 ninety (90) degrees upward. In one example, the Spiraling Wedge 1418 may be molded into the Rotating Wedge 1406. As it is rotated around the Rotating Wedge Pin 1410, the Spiraling Wedge 1418 engages the Rotating Wedge Engagement Flange 1420 located on the Latch 1404. As the Lever 1416 is lifted, the Spiraling Wedge 1418 forces the Latch 1404 to rotate against the tension of the Latch Spring 1412 causing the Latch Foot 1414 to disengage from the Latch Trap Ring 110, thereby allowing the Baffle Assembly 1102 to be removed from the Mounting Frame 104. Note that by lifting the Lever 1416 in a first direction, this causes the Latch to pivot in a second direction.
In many prior art recessed speakers, wires must be attached when inserting the Baffle 1102 and audio transducer 1120 into the Mounting Frame 104. However, the present recessed speaker assembly 100 avoids the step of making separate electrical connections. Instead, Rotating Contact Assemblies 1108 are used and serve both the purpose of tensioning the Latch Assembly's 1104 Latch Foot 1414 against the Latch Trap Ring 110 and to simultaneously provide a means for making an electrical connection to the Mounting Frame 104.
The plurality of Contact Assemblies 1108 engage a plurality of Contact Rings 1702 etched into the Contact PCB 1114 mounted on the Retaining Ring's 108 Connector PCB Support Ring 1110 which in turn is a part of the Mounting Frame 104. The Contact PCB 1114 is positioned within the Retaining Ring's 108 Connector PCB Support Ring 1110 at a distance from the installed Baffle Assembly to allow for appropriate contact to be made with the plurality of Contact Assemblies 1108 located on the Network PCB 1116.
Zero Strip Wire Connection System
Yet another feature provides a wire terminating (connector) device that does not require the wire ends to be stripped of insulation to be terminated. The wire terminating device may be small in dimension, enabling its use in tight quarters. Optionally, the wire terminating device seals the connection from environmentally induced electrical degradation by injecting a silicone grease into areas so exposed, which makes the device particularly advantageous in marine applications. In addition, the connector is able to terminate wires of various gauges, ranging generally from 12 to 18 gauge, including wiring that includes a thick insulation, specifically as may be used in high gauge, stranded loudspeaker wire. This is an unusual advantage as other no-strip devices have a difficult time penetrating varying thicknesses and hardness of insulation.
To make an electrical connection between the inserted wire and the Terminal 2410, a penetrating electrical connection is used comprising a Needle Wire Penetrator 2412, a Needle Shroud 2414, and a Needle Shroud Spring 2416. Once a wire is inserted and electrically coupled to the Terminal 2410, a Grease Pill Piston 2418 can be depressed to push on a Grease Pill 2420 which flows into the Needle Shroud 2414 and serves to insulate the connection to the inserted wire. As can be appreciated in
The sequence of installation is as follows. The installer clips an end of the wire to be inserted (but does not strip the insulator) with a pair of wire cutters to ensure a clean exposure of wire end. The installer takes the Wire Guide 2404 preassembled with a Wire Retainer 2407, and forces the Wire Guide 2404 onto the ends of the wire to be inserted as far as the wire will penetrate into the Wire Guide 2404. The installer then presses down on the Wire Retainer 2407 to lock the wire into place. The Wire Retainer 2407 incorporates a Wire Retainer Ratchet 2422 that engages a pair of non-reversible Wire Retainer Latches 2424 located on the sides of the Wire Guide 2404. The Wire Guide 2404 is able to accommodate varying gauges by employing a tapered, cone shaped hole, referred to here as a Wire Guide Taper 2430. Regardless of the inserted wire diameter, the Wire Guide Taper 2430 always centers the wire. Of course the smaller gauges will move further up the tapered hole 2408 and the larger gauges will not penetrate into the Wire Guide Taper 2430 as far. The advantage of the Wire Guide Taper 2430 is its ability to center/position wires with a large range of diameters.
After the Wire Guide 2404 is securely coupled to the end of the inserted wire, the installer makes a connection by inserting the Wire Guide 2404 into a Wire Guide Receptacle 2432 of the Connector Base 2402. As the Wire Guide 2404 is inserted into the Wire Guide Receptacle 2432, the Wire Guide 2404 encounters and displaces the Needle Shroud 2414, which in turn exposes the tips of the Needle Wire Penetrators 2412 via the Needle Wire Penetrator Guide 2450. Note that as the Needle Shroud 2414 is being pushed back by the Wire Guide 2404, the Needle Shroud Springs 2416 push on the Needle Shroud 2414. The Needle Wire Penetrators 2412 are electrically coupled to corresponding Terminals 2410 and are fixed in place relative to the Connector Base 2402. As the Wire Guide 2404 is inserted into the Wire Guide Receptacle 2432, and because the inserted wire is centered and held fast in the Wire Guide 2404, the Needle Wire Penetrator 2412 is forced into the very end of the inserted wire at some varying position down the Wire Guide Taper 2430 depending on the diameter of the wire and its insulation. Simultaneous with these actions, the Wire Guide Latches 2434 encounters and engages a Wire Guide Latch Ratchet 2436 of the Wire Guide 2404, thereby securing the Wire Guide 2404 in the Connector Base 2402. These features secure the Wire Guide 2404 into the Connector Base 2402 regardless of how far the Wire Guide 2404 enters into the Wire Guide Receptacle 2432. To remove the Wire Guide 2404, the installer may press on the Latch Release Levers 2438 to release the Wire Guide Latch's 2434 hold on the Wire Guide Latch Ratchet 2436. The Wire Guide 2404 can then be pulled free from the Connector Base 2402.
In this manner, the wire connection device 2400 forces a large diameter needle 2412 (e.g., having a nominal shank diameter of about 0.030″) into the exposed end of the inserted wire. This “needle down the end” approach has great advantages over the prior art methods that choose to penetrate the wire insulation from the side. Depending on the wire insulation thickness and hardness, the “side penetrator” approach may or may not come into contact with the inserted wire, let alone yield a reliable contact with the wire. At best, the side penetrator's ability to conduct current is limited due to the limited contact between the penetrator and the wire strands. By contrast, the disclosed “needle down the end” approach offers much higher contact with the wire and, therefore, much better potential for transmitting higher currents.
How far the Wire Guide 2404 enters into the Wire Guide Receptacle 2432 depends on the diameter of wire in use. The smaller the wire diameter the further the Wire Guide 2404 will move into the Connector Base 2402, hence the need for the long Needle Wire Penetrators 2412. When the Needle Wire Penetrator 2412 penetrates the inserted wire end, the wire's insulation may expand slightly to accommodate the added diameter of the Needle Wire Penetrator 2412. With the inserted wire held firmly in the Wire Guide Taper 2430 there would be nowhere for the material to expand. Hence, the Taper Ridges 2440 are arrayed around the diameter of the Wire Guide Taper 2430. These features facilitate the proper positioning of the inserted wire end and allow for a small expansion of the inserted wire's diameter as the Needle Wire Penetrator 2412 moves into the inserted wire end.
Additionally, the wire connector device 2400 is able to inject insulating silicone grease into the cavities after the electrical connection has been made. The grease injection system includes a Grease Pill Piston Guide 2442 molded onto the top of the Connector Base 2402, the Grease Pill Piston 2418, and a pair of Grease Pills 2420. The Grease Pill 2420 may be like a large flexible vitamin pill, with walls that can be ruptured as desired with relative ease. The connector 2402 may be shipped with the Grease Pills 2420 resting loosely on the Pill Tray 2446 and the Grease Pill Piston 2418 placed loosely into the Grease Pill Piston Guide 2442. After the electrical connection has been made, the installer presses firmly down on the Grease Pill Piston 2418. This causes the Grease Pill 2420 to come in contact with the Pill Penetrator 2444 rupturing the Grease Pill 2420. The released grease is forced down through the Wire Guide's 2404 Grease Injection Slots 2448, flooding the cavities with silicone grease, thereby greatly increasing the electrical connection's isolation from environmental effects.
Wall Mounted Loudspeaker Quick Install Bracket System
Another novel aspect provides a wall/ceiling loudspeaker mounting that uses a light-weight, easy to hold and position bracket system that subsequently allows near instantaneous mechanical and electrical installation of its related loudspeaker system. Using a small and light “base bracket” as the first mechanical interface to the wall or ceiling structure makes aligning and securing much more installer friendly.
An electrical interface is included on the Wall Mounting Bracket that allows the installer to make all required electrical connections as part of the initial mechanical installation. This further simplifies the installation as all work is done in the open and not behind something or while holding a heavy, awkward loudspeaker system.
Note that once the Mounting Bracket 3403 has been affixed to a supporting substrate or surface, the pivoting speaker assembly 3400 is a designed so that no additional electrical connections are needed to carry a sound signal to an audio speaker or transducer mounted in the speaker cabinet 3404. When the Mounting Bracket 3403 is attached to the supporting surface, the installer may also attach audio and/or electrical wires (via an access opening 3411) to the wire connector device 2400. The wire connector device 2400 may be electrically coupled to electrical contacts (Mounting Bracket Contacts 3410). The Mounting Bracket Contacts 3410 are mounted within a contact housing 3421. When the Hinge Bracket 3402 is attached to the Mounting Bracket 3403, Hinge Bracket Contacts 3412 come into contact with the Hinge Bracket Contacts 3410, thereby providing audio signals and/or power from the Mounting Bracket 3403 to the Hinge Bracket 3402 without the need for physical wires between the two. Note that the From the Hinge Bracket Contacts 3412 may be coupled to the speaker or audio transducer in the cabinet 3404. Consequently, the Hinge Bracket 3402 and/or speaker cabinet 3404 can be detached from the Mounting Bracket 3403 without the need to disconnect wires.
The Hinge Bracket 3402 carries a pair of electrical contacts (Mounting Bracket Contacts) 3410 that match with a corresponding pair of electrical contacts on the Wall Mounting Frame 3403. These contacts 3410 and 3412 may be gold plated (for corrosion resistance) and may be curved and fabricated from a material that enables them to function in a spring mode, such that, as they slide across one another, they are compressed together facilitating both a cleaning action and making and maintaining good electrical contact. The electrical path is thus connected through these mating contacts 3410 and 3412 after the Hinge Bracket 3402 is slid onto the Wall Mounting Bracket 3403.
The Hinge Bracket 3402 is mounted to and retained by the Wall Mounting Bracket 3403 by sliding the Hinge Bracket's Slider Latches 3414 onto/under the Wall Mounting Bracket's Slider Latches Receptacles 3416.
To facilitate theft resistance, the bracket system incorporates a large Primary Latch 3418 that snaps into place over the Primary Latch Receptacle 3420 just as the loudspeaker assembly is slid fully into place. In order to remove the loudspeaker assembly from the Wall Mounting Bracket 3403, a “De-Latching” Bar 3422 is pried by the installer via Prying Slots 3424 molded into the De-Latcher 3422, along its longitudinal axis. The Prying Slots 3424 are accessed via a slot screwdriver and are pried sufficiently to lift the Primary Latch 3418 via a Lifting Ramp 3426 molded into the De-Latcher 3422.
While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention not be limited to the specific constructions and arrangements shown and described, since various other modifications are possible. Those skilled in the art will appreciate that various adaptations and modifications of the just described embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
