The present disclosure relates to cage tower speaker systems and mounting apparatus of such. More particularly, the present disclosure relates to a cage tower speaker and quick release mounting apparatus adapted for outdoor use mounted on a vehicle.
A variety of systems for housing, amplifying, mounting, and protecting one or more speakers have been developed. Initially, these systems were designed specifically for indoor use and maximizing the user's experience in a home setting. In particular, the cabinets or other structures containing speakers were composed of wood and/or cardboard, and organized to emit and disperse sound to reflect off of nearby walls and ceilings back toward a listener. The advent of speaker systems constructed from plastic and/or metal facilitated portable systems suitable for certain outdoor uses.
Many consumers wish to utilize audio or other multimedia devices while engaging in recreational activities such as power sports, boating, off-roading, etc. Indeed, portable wireless speakers are increasingly used in varied indoor and outdoor environments including boating, off-road driving, and other rugged and potentially weather and water prone environments. Available media players typically draw power from a vehicle battery, requiring conscientious management of battery loading and charge.
However, successfully adapting speaker systems for attachment to various recreational land vehicles, particularly off-road vehicles such as an ATV, dune buggies and similar land vehicles, as well as marine vessels such as ski boats, off-shore recreational fishing boats, party barges and similar watercraft, requires overcoming various problems unique to these land vehicles and watercraft. Sound systems for such vehicles must (1) be impact resistant; (2) provide durable attachment to the vehicle; (3) this durable attachment must also allow for quick and simple adjustments to the position and/or directionality of the speakers to accommodate changes in the listening environment; (4) this durable attachment should also provide a quick and manageable release mechanism to safeguard the mounted speaker system from theft; (5) this quick and manageable release mechanism should prevent the speaker system from falling during removal; (6) provide sufficient audio volume without significantly impacting a vehicle operator's visibility; and (7) protect the electrical components of the speakers from dirt, dust, mud, and/or water.
U.S. Pat. No. 5,191,177 was an early attempt to provide a stable, convenient speaker system for an automobile requiring minimal alteration to the vehicle. This speaker system's convenience relied on the presence of a flat surface within the vehicle for the system to rest upon. Since this system merely rested upon a flat surface within the vehicle, it was limited to on-road trucks and cars, but not suitable to off-road vehicles or watercraft that travel over bumpy terrain such as dusty/muddy trails and choppy water. Such off-road and over-water travel submit sound systems to vigorous physical shaking and jolting requiring very secure attachment to the vehicle or watercraft, as well as construction that could withstand significant mechanical impact. Additionally, this speaker system was constructed from cardboard, further limiting its use to an enclosed interior location of a vehicle as it would not withstand prolonged or repeated exposure to dirt, dust, mud, rain, and/or splashed water, such as from waves, wakes or wet passengers.
U.S. Patent Publication 2008/0141924 presented an alternative speaker assembly especially adapted for use on watercraft. This system solved the problem of water exposure and impact durability by mounting speakers within retractable housings. However, these housings require substantial modification of the watercraft and provide only directional sound aimed rearward toward individuals towed behind the watercraft.
U.S. Pat. No. 8,948,437 improved upon the speaker systems for watercraft by providing vertically oriented sound rods of a stainless steel construction that provide 360° sound in an approximately horizontal plane. However, the mounting system employed is limited to watercraft, and particularly watercraft with existing fishing rod holders that can receive the mounting pole of the sound rod.
U.S. Pat. No. 9,469,254 provided a more versatile mounted speaker system for off-road vehicles, ATVs, UTVs, watercraft, and motorcycles that employs an L-shaped mounting bracket to attach an array of speakers to such vehicles. The L-shaped mounting bracket enables rotation of the speaker array 360° about the plane in which the array is mounted. However, the orientation of the speaker array limits sound dispersion from any given orientation (i.e., rotational position) of the array to a single direction.
U.S. Pat. No. 8,568,162 described a clamp assembly for mounting and suspending loudspeaker assemblies that comprised annular structures that fit within one another. An outer annular structure includes slotted holes that receive prongs from a fork, while an inner annular structure includes a groove that receives the prongs as well, such that the annular structures cannot disengage while the prongs are inserted therein. The configuration of the annular structures allows them to rotate in a plane parallel to the prongs while the fork prongs are engaged. The fork may also include a set screw that locks the annular structures in place, preventing their rotation relative to one another by engaging with the groove of the inner annular structure. However, the clamp assembly requires a tool to fully engage the set screw and lock the annular structures in place, as well as to disengage the set screw. Further, in the absence of the set screw no safeguards exist to prevent either the fork or the loudspeaker from falling.
Although such prior art devices have addressed some of the prior art problems, there remains a need in the industry for a durable speaker mounting system that provides directional adjustable sound and readily releases from a mounted position, thereby reducing or eliminating prior art problems.
A cage tower speaker mounting system and method of use are described herein. In one embodiment, the cage tower speaker mounting system includes an inner annular structure, an outer annular structure, a base mount fixture, a securing plate, and a securing key. The inner annular structure includes a central annulus and an engagement groove encircling the central annulus. The outer annular structure includes an annular surface having a grooved slot. The annular surface contours about an outer diameter of the central annulus of the inner annular structure when the central annulus is inserted into the outer annular structure. The base mount fixture is affixed to one of the inner annular structure and the outer annular structure and includes at least one passage there through. The securing plate abuts the base mount fixture and includes at least one receiving slot having a locking portion and an unlocked portion. The securing key includes at least one prong having a stopping structure and a locking groove. The at least one prong of the securing key extends through the at least one passage of the of the base mount fixture and the unlocked portion of the at least one receiving slot on the securing plate, while also passing along the grooved slot in the annular surface of the outer annular structure and abutting the engagement groove of the central annulus of the inner annular structure. The stopping structure of the securing key abuts the base mount fixture and the locking groove of the at least one prong of the securing key fits within the locking portion of the at least one receiving slot on the securing plate.
In one embodiment, the method of operating the cage tower speaker mounting system includes inserting a central annulus of an inner annular structure into a central annular cavity of an outer annular structure. The central annulus of the inner annular structure includes an engagement groove. The central annular cavity of the outer annular structure surrounds the central annulus of the inner annular structure. The outer annular structure includes an annular surface having a grooved slot. The inner annular structure includes an engagement groove encircling the central annulus. The method of operation proceeds by inserting at least one prong of a securing key through at least one passage of a base mount fixture, along the grooved slot of the annular surface, and through an unlocked portion of at least one receiving slot of a securing plate so that the at least one prong of the securing key abuts the engagement groove of the central annulus.
The present invention will be more fully understood by reference to the following drawings which are presented for illustrative, not limiting, purposes.
Persons of ordinary skill in the art will realize that the following description is illustrative and not in any way limiting. Other embodiments of the claimed subject matter will readily suggest themselves to such skilled persons having the benefit of this disclosure. It shall be appreciated by those of ordinary skill in the art that the apparatus and methods described herein may vary as to configuration and as to details. The following detailed description of the illustrative embodiments includes reference to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the claims.
In various embodiments, the cage tower speaker system disclosed herein may include one or more cage tower speaker unit. In embodiments where the cage tower speaker system comprises multiple speaker units, one of the cage tower speaker units may be a driving speaker unit that includes a battery and amplifier, while the other cage tower speaker units are dummy speakers that lack their own battery, an amplifier, or a combination thereof. In these embodiments, the driving speaker unit provides both power and audio input to the dummy speaker unit(s).
In various embodiments, the one or more cage tower speaker unit may include a removable rechargeable battery within an outer cage tower speaker housing. The outer housing of each cage tower speaker can further include waterproof membranes coupled to the outer housing that serve the dual purpose of releasing a portion of the back pressure generated by the cage tower speaker, as well as, equalizing the internal pressure of the outer housing with the external pressure of the ambient air surrounding the outer housing, while sealing the interior spaces of the outer housing from the outdoor conditions in which the cage tower speaker system operates.
In operation, the waterproof membranes on the outer housing further maintain the structural integrity of the cage tower speaker, its components, and the sound quality emitted therefrom by preventing pressure differentials accumulating between the interior of the cage tower speaker and the exterior of the cage tower speaker due to environmental conditions or back pressures emitted from the cage tower speaker.
In some embodiments, each cage tower speaker unit is removably secured to a vehicle with a mounting bracket having a quick-release engagement mechanism including a pronged securing key, a set screw, and securing plate. The securing plate and pronged securing key of the quick-release engagement mechanism operate to prevent the quick-release engagement mechanism from fully disassembling and allowing the cage tower speaker to fall from its position even when the set screw is removed. The securing plate achieves this operation by receiving one or more prongs of the securing key in corresponding holes and slotting over grooves in each of the prongs, so that the closed end of the fork and the securing plate are situated on opposing sides of the engagement mechanism and the fork cannot readily be removed from the engagement mechanism.

In some embodiments, the rear cavity 126 includes one or more one-way waterproof valves 129. The rear cavity 126 housing the battery 128 forms a rear wall of an interior cavity space housing the speaker driver 108 that separates the interior cavity space from the rear cavity 126. In the illustrative embodiment, a one-way waterproof valve 129 is located on the rear wall of the rear cavity 126, which controls the pressure differential between the interior cavity space and the rear cavity 126. The one-way waterproof valve 129 allows high pressure air to escape the interior cavity space (or isolated sound space) and prevents water, dirt, or mud from entering into the interior cavity.
In some embodiments, the one-way waterproof valve 129 is a membrane barrier operatively, fixedly, or otherwise coupled to the rear wall of the rear cavity 126, such that the membrane barrier covers the opening of a port of hole extending through the rear wall from the rear cavity 126 into the interior cavity space. The membrane barriers 129 may be a waterproof mesh material that allows air to pass through. One exemplary membrane barrier material is expanded polytetrafluoroethylene (ePTFE), especially as prepared by W.L. Gore & Associates, Inc. (i.e., Gore-Tex™). The ePTFE membrane material is a three-dimensional expansion of the linear base polymer PTFE that has a porous structure. In these embodiments where the membrane material is ePTFE, the membrane material may comprise multiple layers having unique compositions, wherein some layers may be the same composition as other layers and different compositions than still other layers. In these embodiments, the membrane barrier may operate by preventing liquid water from passing through while allowing nebulized or evaporate water particles through with air.
In some embodiments, the waterproof valves 129 may be mechanical one-way valves. In some embodiments, the waterproof valves 129 comprise a flap of waterproof material, one portion of which is affixed to a surface (i.e., a wall of the interior cavity and/or a wall of the rear cavity 126), while the remaining portions of the flap are unattached. By only partially affixing the flap of waterproof material to the surface surrounding a port through the surface, the flap may allow water through from the other side of the port, but slam closed when pressure is applied from the side of the surface to which the flap is attached. For example, a flap affixed to the interior surface of the interior sound space so that the flap covers a port from the interior sound space to the rear cavity 126 housing the battery, would swing open due to a pressure exerted from the rear cavity 126 and swing closed due to a pressure exerted from within the interior sound space.
One purpose of the membrane barriers 129 is to prevent a pressure differential from building up between the interior cavity (not shown) and the rear cavity 126 due to heat generated by the operation of the speaker driver assembly 108 and the extreme environments in which the cage tower speaker 100 operates, i.e. high air temperature and direct sunlight, or freezing temperatures. By allowing air to pass through the membrane barrier(s) 129, the membrane barrier(s) 129 act to conduct heat into or out of the interior cavity. Back pressure generated by the speaker driver assembly 108 may also escape through the membrane barrier(s) 129. A further purpose of the membrane barriers 129 is to allow pressure equalization between the rear cavity 126 and the interior sound space, without allowing any water to enter the rear cavity 126. Thus, the membrane barriers 129 may protect the rechargeable removable battery 128 from water and/or moisture.
The membrane barrier(s) 129 also prevent pressure from accumulating within the isolated sound space (i.e., acoustic-suspension box) that is the interior cavity for the speaker driver assembly 108, otherwise the pressure may accumulate until it is sufficient to dislodge the speaker driver assembly 108. Should the speaker be dislodged in this manner, it would decrease the sound quality produced by the cage tower speaker 100 by adding unintended vibrations from the dislodged speaker assembly 108. Further, water seeping through a dislodged element into the interior of the outer housing 102 may degrade or short-out internal electrical connections between the speaker 108 and either the control panel 118 or the battery 128. Further, water seeping through a dislodged element into the interior of the outer housing 102 may enter the control panel 118 itself. Water seeping into the interior sound space may corrode and/or short any of the control panel connections or elements, such as the electrical ports 124A and 124B. Such water damage would shorten the operable life span of the cage tower speaker 100 or disable it entirely. However, the membrane barrier(s) 129 limit, prevent, and/or eliminate such degradation of the cage tower speaker 100 and extend its operable life span.
At the same time, although not necessarily so, the membrane barrier(s) 129 equalize the internal pressure present within the interior of the outer housing 102 (i.e., the interior sound space 130) with the pressure in the rear cavity 126, by allowing air to pass into or out of the interior of the outer housing 102 through the membrane barrier (not shown) without allowing water, dirt, or other debris to enter the outer housing 102 interior.
In some embodiments, when enclosed by the rear cover, the rear cavity 126 is a sealed, watertight compartment that protects the battery 128 and other interior electrical components of the cage tower speaker 100. The seal may be formed by a rubber O-ring or comparable sealing element seated about the exterior border of the rear cavity 126 and between the rear cavity 128 and the rear cover.

The cutaway view of
The sound waves and/or back pressure generated by the speaker driver 108 are directed by the rear wall of the interior cavity space 130 outward back toward the frontal opening. In this manner, the interior cavity space 130 acts as an acoustic-suspension box or air-suspension box that cause back pressure or sound waves generated by speaker driver 108 to be directed outward along the lengthwise axis of the cage tower speaker 100 from the speaker driver 108 and the cage tower speaker 100.
In operation, the cage tower speaker 100 emits sound waves from the speaker driver assembly 108 according to input received from the control panel 118. The input may be the result of a user pressing one or more of the buttons on the control panel 118 or from a music file uploaded, input, or otherwise present upon a processor (not shown) of the cage tower speaker 100. In the illustrative embodiment, the speaker driver assembly 108 is located in the frontal circular opening of the outer housing 102 and emits sound waves outward from the frontal circular opening along a central lengthwise axis of the outer housing 102, while simultaneously emitting sound waves and/or back pressure into the interior sound space 130 also along the central lengthwise axis to rear wall of the interior cavity 130.
User commands input at or through the control panel 118 may also control the operation of the LED lights resident within the speaker 108. However, the operation of the various LED lights may be automated in conjunction with music played by the cage tower speaker 100 and require no specific input from a user.

The clamp 904 includes an upper portion 908 and a lower portion 910 that may be affixed about a pipe, pole, tube, rod, or other structure, particularly structures present on a vehicle. The upper portion 908 and lower portion 910 of the clamp 904 form a cavity or hole through which the pipe, pole, tube, rod, or other structure may extend. The upper portion 908 and lower portion 910 of the clamp 904 may be secured to one another with screws or similar fasteners (not shown) passing through receiver holes 912 extending through both the upper portion 908 and lower portion 910 of the clamp 904.
The clamp 904 also includes an electrical connector passage 914 that may receive or comprise multi-pin aviator connectors, deutsch connectors, or comparable electrical connections. The electrical connector passage 914 is central to the clamp 904 and aligned along an axis of rotation of the mounting bracket 104 so that the electrical connector passing there through may rotate without twisting unduly or binding upon itself and/or the structures of the mounting bracket 104.
In some embodiments, the electrical connector passage 914 passes through the lower portion 910 of the clamp 904, such that it is oriented to allow an electrical connector or electrical lines to pass through the lower portion 910 of the clamp 904 into a pipe, pole, tube, rod, or other structure to which the mounting bracket 104 is affixed.
A pronged securing key 916 couples the mount base 902 to the clamp 904 by extending through a quick-release engagement mechanism (not shown). The securing key 916 may be a fork structure constructed from plastic, metal (e.g., aluminum, titanium, steel, stainless steel), metal alloy, composite, carbon fiber, or any other suitable material. The securing key 916 and quick-release engagement mechanism (not shown) allows the mount base 902 and clamp 904 to swivel, pivot, or rotate with respect to one another, and thus allows a cage tower speaker unit affixed to the mount base 902 to swivel, pivot, or rotate with respect to any pipe, pole, tube, rod, or other structure to which the clamp 904 is affixed. In the illustrative embodiment, the mount base 902 rotates in a horizontal plane 918 that is perpendicular and orthogonal to the vertical alignment 920 of the mounting bracket 104.
The set screw assembly 926 threads into the threaded set hole (not shown) of the securing plate 922. When threaded fully into the threaded set hole (not shown), the set screw assembly arrests the rotation of the mounting bracket 104, locking the mount base 902 and the clamp 904 in a particular rotational orientation. Additionally, when threaded fully into the threaded set hole (not shown), the set screw assembly locks the securing key 916, securing plate 922, and engagement mechanism (not shown) together and prevents any cage tower speaker unit affixed thereto from falling from its mounted position.

The illustrative securing key 916 has cylindrical prongs 916A and 916B with circular cross-sections. In some embodiments, the prongs 916A and 916B may instead be bars having oval cross-sections, square cross-sections, rectangular cross-sections, triangular cross-sections, or a comparable geometric cross-sectional shape.
The base fixture 928 may be constructed of metal (e.g., aluminum, titanium, steel, stainless steel), a metal alloy, a composite, plastic, carbon fiber, and a combination thereof. The base fixture 928 includes one or more receiving holes 938 that pass through the base fixture 928 from a rear side of the base fixture 928 (not shown) to a front side of the base fixture 928. In various embodiments, the base mount fixture includes a number of receiving holes 938 corresponding to the total number of securing key prongs employed by the base mount 902 (e.g., the base fixture 928 may include two receiving holes 938 when the base mount 902 includes two single pronged securing keys or one two-pronged securing key 916). The receiving holes 938 are sized and configured to receive the prongs 916A and 916B of the securing key 916 so that the prongs 916A and 916B pass through the base fixture 928 and the slot(s) 924 of the securing plate 922 when the securing key 916 is fully inserted into the receiving holes 938. Thus, the diameter of the receiving holes 938 are greater than the outer diameter of the prongs 916A and 916B. However, the diameter of the receiving holes 938 are smaller than the diameter of the stopping collars 934. The securing key 916 is fully inserted into the base fixture 928 when the stopping collar(s) 934 abuts the base fixture 928 and cannot be inserted further into the base fixture 928.
The base fixture 928 further includes a set screw hole 939 that receives the stopper screw 930 and/or the set screw 926. The set screw hole 939 does not pass entirely through the base fixture 928, instead passing only from the front exterior of the base fixture 928 into an interior space surrounding the outer annular structure 932 and receives the inner annular structure 952. In the illustrative embodiment, the set screw hole 939 is circular and of a diameter larger than the outer diameters of both the set screw 926 and the stopper screw 930 head. In some embodiments, the set screw hole 939 is slot-shaped with a width that is larger than the outer diameter of the set screw 926, but narrower than the outer diameter of the stopper screw 930 head. In some embodiments, the set screw hole 939 is slot-shaped with a width that is larger than the outer diameters of both the set screw 926 and the stopper screw 930 head.
In the illustrative embodiment, the slot 924 includes a narrow locking portion situated directly above a wide unlocked portion. The wide portion of the slot 924 is sized larger than an outer diameter of the securing key prongs 916A and 916B and configured to receive the prongs 916A and 916B. The narrow locking portion of the slot 924 is sized smaller than the outer diameter of the securing key prongs 916A and 916B so that the prongs 916A and 916B cannot pass through the narrow locking portion of the slot 924. However, the narrow locking portion of the slot 924 is sized larger than the diameter of the locking grooves 936 so that the prongs 916A and 916B may slide into the narrow locking portion of the slot 924 when the slot 924 is aligned with the locking groove 936.
The stopper screw 930 includes threading along a shaft that is narrower than the outer diameter of the set screw 926. The threaded shaft of the stopper screw 930 meshes with threading internal to the set screw 926. When threaded into the set screw 926, the stopper screw 930 and set screw 926 together comprise the set screw assembly. The stopper screw 930 includes a head adjacent to the inner annular structure 928 that has a larger diameter than the shaft of the set screw 926 and the hole 940 in the securing plate 922 through which the set screw 926 passes. This head of the stopper screw 930 prevents the set screw assembly from being removed from the securing plate 922 without disassembling the set screw assembly, i.e., removing the stopper screw 930 from the set screw 926. In the illustrative embodiment, the set screw 926 is a machine screw having a hex head that requires an Allen wrench or hex key to tighten, loosen, or remove. In some embodiments, the set screw assembly instead includes a hand-held set screw 926B that can be tightened, loosened, or removed by hand and without any tools. The hand-held set screw 926B includes a knob instead of a hex-key head or bolt head. The knob is sized and contoured to be gripped and operated by hand.
The outer annular structure 932 fits within and may be secured to the base fixture 928. In some embodiments, the outer annular structure 932 is secured to the base fixture 928 with screws or fasteners. In some embodiments, the outer annular structure 932 is an integrated component of the base fixture 928. In some embodiments, the outer annular structure 932 is affixed to, or integrated with, the clamp 904 instead of the base fixture 928. The outer annular structure includes one or more slot structures 942 and a central annular cavity 944. The slot structures 942 are oriented horizontally and configured to allow the prongs 916A and 916B to pass there through. The central annular cavity 944 is oriented vertically and orthogonal to the slot structures 942.
The clamp 904 includes an upper portion 908, an upper inlay 946, a lower portion 910, a lower inlay 948, clamp fasteners 950, and an inner annular structure 952. The upper inlay 946 is contoured to fit within the clamp upper portion 908 and the lower inlay 948 is contoured to fit within the clamp lower portion 910. Either or both of the upper inlay 946 and the lower inlay 948 may include a cushioned and/or textured surface configured to contact a pipe, pole, tube, rod, or other structure about which the clamp 904 may be affixed. In some embodiments, the cushioned and/or textured surface includes a rubber layer, a foam layer, or a layer of comparable material.
The clamp fasteners 950 may be machine screws, bolts, or comparable fasteners that are configured to pass through receiving holes in the clamp upper portion 908 and into a nut-plate or threaded hole in the clamp lower portion 910. Thus, the clamp fasteners 950 may secure the clamp upper portion 908 to the clamp lower portion 910 about a pipe, pole, tube, rod, or other structure, thereby affixing the mounting bracket 104 and any cage tower speaker unit attached thereto, such as to a vehicle or other structure. In some embodiments, the clamp fasteners 950 further secure the upper inlay 946 and/or the lower inlay 946 about a pipe, pole, tube, rod, or other structure and within the clamp upper portion 908 and lower portion 910, respectively. In the illustrative embodiment, the clamp lower portion includes a central passage 914A through which electrical connectors may pass. Similarly, the lower inlay 948 may include a central passage 914B through which electrical connectors may pass.
In the illustrative embodiment, the inner annular structure 952 includes a central annulus 954. In the illustrative embodiment, the inner annular structure 952 may be secured to a bottom surface of the clamp 904, such as a bottom surface of the clamp lower portion 910. In some embodiments, the inner annular structure 952 is secured to the bottom surface of the clamp 904 or clamp lower portion 910 with screws or fasteners. In some embodiments, the inner annular structure 952 is an integrated component of the clamp lower portion 910. In some embodiments, the inner annular structure 952 is affixed to, or integrated with, the base fixture 928 of the base mount 902 instead of the clamp 904.
In the illustrative embodiment, the central annulus 954 has an outer diameter sized and configured to fit within the central annular cavity 944 of the outer annular structure 932. Similarly, the annular surfaces of the outer annular structure 932 that delineate the central annular cavity 944 are contoured to correspond to the shape and size of the inner annular structure's central annulus 954, i.e. the annular surfaces are contoured to extend about and around the central annulus 954. Together, the clamp lower portion central passage 914A, the lower inlay central passage 914B, the outer annular structure 932 central annular cavity 944, and the inner annular structure 952 central annulus 954 form the electrical connector passage 914 (shown in
The inner annular structure 952 and the outer annular structure 932 operate together to form an engagement mechanism when the securing key 916 is inserted through the base fixture 928 and the outer annular structure 932, so that the prong(s) of the securing key 916 abut an engagement groove of the central annulus 954. When so engaged, the engagement mechanism affixes the base mount 902 to the clamp 904, while allowing the base mount 902 to rotate with respect to the clamp 904.

In the illustrative embodiment, a stopping collar or band 934 having a diameter greater than the outer diameter of the prongs 916A and 916B abuts the base mount 902 to prevent the prongs 916A and 916B from passing entirely through the base mount 902 and stop the securing fork 916 at a fully inserted position. In the illustrative embodiment, the slot or hole 938 in the base mount 902 through which the prong(s) 916A and/or 916B extend includes an inset 956 that receives the stopping collar or band 934. In this illustrative embodiment, the prongs 916A and 916B include a locking groove 936 which is configured to rest within a narrow locking portion of the slot 924 in the securing plate 922.
In the illustrative embodiment, a set screw assembly 958 includes the set screw 926 and the stopper screw 930 that abuts the inner annular structure 952 when the set screw assembly 958 is fully engaged through the securing plate 922 and the set screw hole 939. As described above, the stopper screw 930 includes threading along a shaft that is narrower than the outer diameter of the set screw 926. When the threaded shaft of the stopper screw 930 meshes and engages with threading internal to the set screw 926, the two components form an assembled set screw assembly 958. The stopper screw 930 includes a head that may be placed adjacent to the inner annular structure 952. In the illustrative embodiment, the stopper screw 930 head has a larger diameter than the shaft of the set screw 926 and the hole 940 in the securing plate 922 through which the set screw 926 passes. The stopper screw 930 head prevents the set screw assembly 958 from being removed from the securing plate 922 without disassembling the set screw assembly 958, i.e., removing the stopper screw 930 from the set screw 926.
In the illustrative embodiment, the hole 940 includes internal threading that meshes and engages with the external threading along the shaft of the set screw 926. The internal threading of the hole 940 in the securing plate 922 enables the incremental movement of the set screw assembly 958 through the securing hole 940 so that the set screw assembly 958 may be secured in a fully engaged position where the head of the stopper screw 930 firmly abuts the engagement groove of the central annulus 954. The internal threading of the hole 940 also enables removal of the set screw assembly 958 from the set screw hole 939 by placing the set screw assembly 958 in a removed position or unlocked position.
In the illustrative embodiment, the set screw hole 939 is circular and of a diameter larger than the outer diameters of both the set screw 926 and the stopper screw 930 head. In this illustrative embodiment, the set screw assembly 958 must be removed from the set screw hole 939, i.e. be placed in the removed or unlocked position, so that the set screw assembly 958 and the securing plate 922 can be shifted up into an unlocked position that orients the prong(s) 916A and/or 916B through the wider unlocked portion of the receiving slot 924. Once oriented through wider unlocked portion of the receiving slot 924, both the securing plate 922 and the set screw assembly 958 can be removed from the base mount 902. With the securing plate 922 and the set screw assembly 958 removed, the securing key 916 can then be removed from the engagement mechanism, i.e., the base fixture 928 and the outer annular structure 952, so that the base mount 902 and any speaker unit affixed thereto can be stored or moved to another mounting location.
When the set screw assembly 958 is placed in the unlocked position, the orientation of the narrow locking portion of the receiving slot 924, above the wider unlocked portion of the receiving slot 924, causes gravity to hold the securing plate 922 within the locking groove 936 of the securing key prong 916A or 916B and prevent the securing plate 922 from simply slipping off the securing key prong 916A or 916B and falling. This mechanism simplifies the operation of the mounting bracket 104, reducing the likelihood that the securing plate 922 could become lost.
In operation, the weight of a speaker unit affixed to the base mount 902 creates a modicum of friction that prevents the securing key 916 from simply slipping out of the base fixture 928 and the outer annular structure 952, thus continuing to hold the mounting bracket 104 together.
When the set screw assembly 958 is placed in the unlocked position, the wider unlocked portion of the receiving slot 924 on the securing plate 922 can be passed over the prong(s) 916A and/or 916B of a securing key 916 inserted through the outer annular structure 952 and base fixture 928. Once the prong(s) 916A and/or 916B of the securing key 916 have been placed into the wider unlocked portion of the receiving slot 924 on the securing plate 922, the securing plate 922 can be shifted down into a locked position where the narrower locking portion of the receiving slot 924 slides over or into the locking groove 936 of the securing key prong 916A or 916B. Once in this locked position, the set screw assembly 958 aligns with the set screw hole 939 and the set screw assembly can be tightened into an engaged position where the stopper screw 930 abuts the central annulus 954.
In the illustrative embodiment, the hole 940 through which the set screw assembly 958 passes includes a spacing sleeve 960 protruding from a surface of the securing plate 922. The distance which the spacing sleeve 960 protrudes outward from the securing plate 922 surface corresponds to the length of the set screw assembly 958 and the distance to the inner annular structure 952 so that the stopper screw 930 only abuts the inner annular structure 952 when the set screw assembly 958 is fully inserted into the spacing sleeve 960.

The interior of the central annulus 954 forms a cavity through the center of the inner annular structure 952. The exterior of the central annulus 954 is ribbed or ringed to provide horizontal recesses about the circumference of the central annulus 954. In the illustrative embodiment, these recesses form the engagement groove 964, the upper o-ring groove 966, and the lower o-ring groove 968. The engagement groove 964 has a diameter less than the outer diameter of the central annulus 954. The diameter of the engagement groove 964 is also less than the width between the prongs 916A and 916B of the securing key 916, so that the prongs 916A and 916B of the securing key 916 can pass around and/or abut the engagement groove 964. However, the outer diameter of the central annulus 954 is greater than the width between the prongs 916A and 916B of the securing key 916, so that the prongs 916A and 916B of the securing key 916 cannot pass around the outer diameter of the central annulus 954. This configuration of the securing key 916, the outer diameter of the central annulus 954, and the diameter of the engagement groove 964 prevents the inner annular structure from shifting vertically, either up or down, while the securing key 916 is engaged in the base fixture 928 and about the engagement groove 964 of the inner annular structure 952. In the illustrative embodiment, the cylindrical shape of the central annulus 954 enables the inner annular structure 952 to rotate between the prongs 916A and 916B of the securing key 916, and within the outer annular structure 932.
The upper o-ring groove 966 and the lower o-ring groove 968 are configured to receive seals or o-rings formed from rubber, silicon, or a comparable sealant. The orientation of the upper o-ring groove 966 above the engagement groove 964 and the lower o-ring groove 968 below the engagement groove 964 allows o-ring seals placed in the upper o-ring groove 966 and the lower o-ring groove 968 to seal the cavity of the central annulus and any electrical wiring or connector therein or passing there through.

In the illustrative embodiment, the engagement groove 964 is shallow, such that the outer diameter of the central annulus 954 does not extend around or over the full diameter of a securing key prong (not shown) abutting the engagement groove 964. In some embodiments, the engagement groove 964 is deep, such that the outer diameter of the central annulus 954 extends around or over the full diameter of a securing key prong (not shown) abutting the engagement groove 964. Embodiments having a deep engagement groove 964 may be especially useful when the securing key includes only a single prong.

In the illustrative embodiment, the central annular cavity 944 is only partially delineated and/or surrounded by the annular wall 972, such that gaps exist between annular walls 972 on a first side and a second side opposite the first side of the central annular cavity 944. In some embodiments, the annular surface 974 of the annular wall 972 delineates and surrounds the entirety of the central annular cavity 944. In the illustrative embodiments, the annular surface 974 is curved in correspondence to the cylindrical shape of the central annular cavity 944. In this illustrative embodiment, the annular supports 976 are oriented perpendicular to the length and longitudinal axis of the slot structures 942. The annular supports 976 include slot holes 978 that are each sized and configured to receive one prong 916A or 916B of the securing fork 916 and allow that prong to pass through the slot hole 978. In the illustrative embodiment, each annular wall 972 includes a front and rear annular support 976, which each also include slot holes 978. Thus, in the illustrative embodiment, each annular wall 972 includes a front slot hole 978 and rear slot hole 978. one prong 916A or 916B of the securing fork 916.
The illustrative annular supports 976 abut an annular surface 974 that includes a grooved slot 980, which is sized and configured to receive one prong 916A or 916B of the securing fork 916. In the illustrative embodiment, the prongs 916A and 916B of the securing fork 916 do not pass through the grooved slot 980, but instead run within the grooved slot 980 and along the length of the grooved slot 980. Thus, in operation a prong 916A or 916B of the securing fork 916 passes through a front slot hole 978 of an annular support 976 abutting an annular surface 974, lengthwise within the grooved slot 980 of that annular surface 974, and then passes through the back slot hole 978 of a second annular support 976 abutting that annular surface 974.
This view shows that the slot structure 942 forms a linear, hollow cylindrical path through the front annular support 976, along a portion of the annular surface 974 abutting the front annular support 976, and through the rear annular support 976 abutting that annular surface 974.
