Description

Technical Field

[0001] The utility model relates to the technical field of speaker connection, in particular to a wall-mounted constant curvature array speaker. Background Art

[0002] A speaker is a device that converts electrical signals into sound signals, and authenticity is a key criterion for evaluating speaker performance. Active speakers are audio systems equipped with a power amplifier (or PA). This integrated amplifier and speaker system can be directly paired with common audio sources (such as portable players, CD players, DVD players, and VCRs) to create a complete audio system. When speakers need to be used in a higher location, they are typically mounted directly on a speaker stand or wall-mounted on a wall or building surface.

[0003] In some specific situations, it is necessary to arrange multiple speakers in sequence to form an array speaker to improve the directivity range of the sound source. For example, the installation structure of the array speaker disclosed in patent CN215222424U includes a support frame connected to the bottom side wall of the array speaker, multiple speaker bodies are connected by a connecting plate at the rear side, and the support frame is fixed to the wall via a fixing seat. This structure is mainly used when the array speaker is placed vertically. However, in actual applications, there are also situations where multiple speaker bodies are arranged in a circular array. The existing technology often lacks a suitable suspension structure for such circumferential array speakers, resulting in poor stability when the array speaker is hung and connected, and inconvenient adjustment of the speaker's tilt direction. Utility Model Content

[0004] In order to overcome at least one of the defects in the above-mentioned prior art, the present invention provides a wall-mounted constant curvature array speaker, which realizes the stable suspension installation of the circumferential array speaker, and the inclination angle of the array speaker is easily adjustable to suit a variety of different scenarios.

[0005] The utility model provides a wall-mounted constant curvature array speaker: it includes at least two speaker bodies and a suspension assembly, each of the speaker bodies can be detachably assembled into one body, the suspension assembly includes a suspension beam, the middle part of the suspension beam is provided with a suspension through-hole for connecting to a set hanging point, both ends of the suspension beam are respectively provided with a suspension arm that can be adjusted along its length direction, the lower ends of the two suspension arms are connected to a connecting cross bar, the two connecting cross bars are respectively detachably connected to the top of the speaker body at two corresponding positions, and each of the connecting cross bars is respectively extended along the front and rear directions of the speaker body, and the two connecting cross bars are respectively provided with a plurality of first connecting holes arranged along their length direction, and the two hanging arms are respectively detachably connected to the corresponding first connecting holes on the two connecting cross bars.

[0006] Compared with the prior art, the wall-mounted constant curvature array speaker of the present invention has the following advantages:

[0007] In the array speaker structure of the present invention, the suspended installation of the array speaker is achieved through a special suspension component, and hanging arms are provided at both ends of the suspension beam in the suspension component, and the lower ends of the two hanging arms are detachably connected to the two corresponding speaker bodies through connecting cross bars, thereby achieving stable suspension of the array speaker; more importantly, the two hanging arms at both ends of the suspension beam in this structure are adjustable in position along the length direction of the suspension beam, thereby achieving adjustment of the spacing between the two hanging arms, so that the user can choose two adjacent speaker bodies for connection when hanging, or choose two spaced-apart speaker bodies for connection, thereby increasing the scope of application; in addition, a plurality of first connecting holes are also provided on the two connecting cross bars. When the two hanging arms cooperate with the first connecting holes in different positions, the tilt direction of the array speaker can be adjusted to adapt to the adjustment of the sound directivity distance in different scenes.

[0008] As an improvement, fixing plates are provided at both the front and rear ends of the top plate of each speaker body, each fixing plate having a gourd-shaped hole, and countersunk holes are provided on the top plate at positions corresponding to the gourd-shaped holes. I-shaped nails are connected to the lower portion of each longitudinal end of each connecting crossbar for snap-fitting with the gourd-shaped holes. In the above structure, the two connecting crossbars are detachably connected to the fixing plates on the top plate of the speaker body through the snap-fitting of the gourd-shaped holes and the I-shaped nails, resulting in a simple structure and easy assembly and disassembly.

[0009] Further improved, each of the gourd holes includes a small-diameter hole and a large-diameter hole arranged in a front-to-back manner along the speaker body and interpenetrating with each other, a first positioning hole is provided on the fixing plate at the rear end of the top plate, a second positioning hole is provided at one end of the connecting crossbar, and a first locking pin is inserted into the second positioning hole. When the two ends of the connecting crossbar are respectively clamped into the two gourd holes on the top plate from back to front through two I-shaped nails, the first positioning hole corresponds to the second positioning hole, and the lower end of the first locking pin is inserted and fitted into the first positioning hole. In the above-mentioned improved structure, the provision of the first locking pin structure prevents the connecting crossbar from moving horizontally after being clamped to the fixing plate, thus preventing the I-shaped nails from falling out of the gourd holes and ensuring the stability of the connection structure.

[0010] Preferably, each of the hanging arms includes at least two U-shaped rings connected in series, and a plurality of second connection holes arranged along the length of each hanging arm are provided at both ends of the suspension beam. The U-shaped ring at the top end of each hanging arm is detachably connected to the second connection hole at the corresponding end, and the U-shaped ring at the bottom end is detachably connected to the corresponding first connection hole. In the above structure, the hanging arms are formed by connecting the U-shaped rings in series, and their length can be adjusted by increasing or decreasing the number of U-shaped rings. In addition, the U-shaped ring at the top end cooperates with the second connection holes at different positions on the suspension beam to adjust the distance between the two hanging arms, which is very convenient.

[0011] As a further improvement, the middle portion of the top plate of each speaker body is further connected to a hand-held connecting plate extending along its width direction, and the middle portion of the top plate is further provided with a concave air-avoiding groove located below the hand-held connecting plate. The upper surfaces of both ends of the hand-held connecting plate are respectively provided with a first concave accommodating groove and a second concave accommodating groove. The first accommodating groove is hingedly connected to a flip lock block at one end close to the side wall of the speaker body, and a positioning lock hole is provided at the end of the flip lock block away from the hinge axis. A second lock pin is slidably penetrated through one side wall of the second accommodating groove and extended to be inserted into the other side wall. When two adjacent speaker bodies are assembled, the flip lock block on one speaker body is flipped and fitted into the second accommodating groove on the adjacent speaker body, and the second lock pin is penetrated into the positioning lock hole. In the above structure, the connection structure between adjacent speaker bodies is simple and easy to assemble and disassemble.

[0012] In a further improvement, a permanent magnet is embedded in the middle of the flip lock block. When unlocked, the flip lock block flips back and forth, attracting and storing it in the first receiving groove. In this improved structure, the permanent magnet allows the flip lock block to be attracted and stored in the first receiving groove when unlocked, preventing the flipping back and forth from generating noise and affecting the sound quality.

[0013] Other improved features and advantages of the present invention will be described in the following detailed description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purposes and other advantages of the present invention can be achieved and obtained by the structures specifically pointed out in the description and the drawings.

Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0023] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be in direct contact with the first and second features, or the first and second features may be in indirect contact through an intermediate medium.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figures 1 to 5 As shown, an embodiment of the present application discloses a wall-mounted constant curvature array speaker, comprising at least two speaker bodies 1 and a suspension assembly, wherein each speaker body 1 is detachably assembled into one body, specifically a circumferential array speaker, i.e., a plurality of speaker bodies 1 are arranged in an array along a circumferential direction, so as to realize the circumferential range expansion of the sound source directivity according to the actual scene requirements.

[0026] In the above structure, the suspension assembly includes a suspension beam 2, and a suspension through-hole 3 for connecting to a set hanging point is provided at the middle position of the upper end of the suspension beam 2. When connected, a fastener is passed through the suspension through-hole 3 to connect it to the corresponding height position. In addition, the two ends of the lower part of the suspension beam 2 are respectively provided with hanging arms that can be adjusted along their length, and the lower ends of the two hanging arms are connected to a connecting crossbar 4. The two connecting crossbars 4 are detachably connected to the top of the speaker body 1 at two corresponding positions. In this structure, the two speaker bodies 1 used to connect the suspension assembly can be selected according to the actual connection point, that is, the two connecting crossbars 4 below the suspension beam 2 can be connected to two adjacent speaker bodies 1, or can be connected to two speaker bodies 1 spaced apart from each other, and the specific selection is based on the spacing between the two hanging arms.

[0027] More specifically, in this embodiment, each connecting crossbar 4 extends along the front-to-back direction of the speaker body 1, and each of the two connecting crossbars 4 is provided with a plurality of first connecting holes 5 arranged along its length. The two hanging arms are detachably connected to the corresponding first connecting holes 5 on the two connecting crossbars 4. In this structure, the tilt direction of the speaker body 1 can be adjusted based on the position of the lower ends of the two hanging arms and the corresponding first connecting holes 5. That is, when the first connecting holes 5 connected to the lower ends of the two hanging arms are located at the center of gravity of the speaker body 1, the mounted array speaker is in a horizontal position. When the array speaker needs to be adjusted to tilt the front side downward, the connection points of the two hanging arms and the connecting crossbars 4 can be moved backward. Conversely, when the connection points of the two hanging arms and the connecting crossbars 4 are moved forward, the front end of the array speaker can be lifted upward.

[0028] In this embodiment, preferably, each connecting crossbar 4 includes a transverse base plate and two vertical ribs, the two vertical ribs being welded to the upper surface of the transverse base plate at intervals, and each vertical rib is provided with a plurality of first communication holes evenly arranged along its length. I-shaped nails 8 are connected to both ends of the lower surface of each transverse base plate. The I-shaped nails 8 can be directly welded to the transverse base plate or fixed by threaded connection.

[0029] In the above structure, see the attached Figure 3 、 4 The detachable connection between the connecting cross bar 4 and the top of the speaker body 1 means that fixing plates 6 are provided at the front and rear ends of the top plate of each speaker body 1, and each fixing plate 6 is provided with a gourd hole 7, and an avoidance countersunk hole is provided at a position corresponding to the gourd hole 7 on the top plate; the lower part of each end of the connecting cross bar 4 in the length direction is connected with an I-nail 8 for fitting with the gourd hole 7.

[0030] More specifically, in this embodiment, each gourd hole 7 includes small-diameter holes and large-diameter holes arranged in a front-to-back manner along the speaker body 1 and interconnected, and the diameter of the horizontal nail cap of the I-shaped nail 8 is larger than the small-diameter hole and smaller than the large-diameter hole; that is, when the connecting cross bar 4 is connected to the fixing plate 6, the I-shaped nail 8 is inserted from the position of the large-diameter hole, and then moved horizontally until the I-shaped nail 8 is clamped in the small-diameter hole, and the clamping positioning of the connecting cross bar 4 and the fixing plate 6 is achieved by limiting the horizontal nail cap.

[0031] In this embodiment, in order to further ensure the stability of the mounting structure of the connecting crossbar 4 and the fixing plate 6 and to avoid the horizontal movement of the connecting crossbar 4 backward, which may cause the I-nail 8 to be detached from the large-diameter hole, a first positioning socket 9 is provided on the fixing plate 6 at the rear end of the top plate of the speaker body 1, and a second positioning socket 10 is provided at the corresponding end of the connecting crossbar 4, and a first locking pin 12 is inserted into the second positioning socket 10. When the two ends of the connecting crossbar 4 are respectively mounted in the two gourd holes 7 on the top plate from back to front through the two I-nail 8, the first positioning socket 9 corresponds to the second positioning socket 10, and the lower end of the first locking pin 12 is inserted into the first positioning socket 9, which is used to limit the horizontal direction of the connecting crossbar 4 and prevent it from moving horizontally backward.

[0032] In the above structure, each hanging arm includes at least two U-shaped rings 13 connected in series with each other, and both ends of the suspension beam 2 are provided with a plurality of second connection holes 14 arranged along its length direction. The U-shaped ring 13 at the upper end of each hanging arm can be detachably connected to the second connection hole 14 at the corresponding end of the suspension beam 2, and the U-shaped ring 13 at the lower end can be detachably connected to the corresponding first connection hole 5.

[0033] On the other hand, in this embodiment, see the attached Figure 5A portable connecting plate 15 extending along its width direction is also connected to the middle part of the top plate of each speaker body 1, and a concave air-avoiding groove 16 is also provided in the middle part of the top plate below the portable connecting plate 15. The upper surfaces of the two ends of the portable connecting plate 15 are respectively provided with a concave first accommodating groove 17 and a second accommodating groove 18. The first accommodating groove 17 is hinged to one end of the speaker body 1 near the side wall of the speaker body 1, and a positioning lock hole 20 is opened at the end of the flip lock block 19 away from the hinge axis. A second lock pin 21 extending and inserted into the other side wall is slidably penetrated on one side wall of the second accommodating groove 18; when two adjacent speaker bodies 1 are assembled, the flip lock block 19 on one of the speaker bodies 1 is flipped and fitted into the second accommodating groove 18 on the adjacent speaker body 1, and the second lock pin 21 is penetrated in the positioning lock hole 20 to realize the assembly and connection of the adjacent speaker bodies 1. In the above structure, more specifically, the portable connecting plate 15 is made of metal, and both ends of the portable connecting plate 15 and both sides in its width direction are folded upward to form corresponding accommodating grooves, and the bottoms of the two accommodating grooves are respectively connected to the top plate of the speaker body 1 through fasteners. In order to facilitate the user to hold the speaker body 1 with one hand through the portable connecting plate 15, a plastic shell is installed on the outside of the middle part of the portable connecting plate 15, which is convenient for carrying and increases the appearance.

[0034] In this embodiment, a permanent magnet is embedded in the middle of the flip lock block 19. When in the unlocked state, the flip lock block 19 flips back and forth and is attracted and accommodated in the first receiving groove 17 to prevent the flip lock block 19 from flipping back and forth and generating noise when in the unlocked state.
