Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a double-row matrix speaker audio system. Background Art

[0002] A dual-row matrix speaker system is a specialized audio system typically consisting of two speakers arranged in a matrix. This system utilizes multiple speaker units arranged in a matrix, achieving expressive sound and a stereo effect through the combination of these units. Matrix speaker systems offer excellent sound quality, high reliability, and stereoscopic sound, making them widely used in a variety of applications, including audiovisual entertainment and home theaters.

[0003] During use, multiple sets of speakers are installed in different directions to achieve directional sound propagation. When the sound of the speakers is directed in one direction, the sound in that direction will be relatively louder. This is because the propagation of sound is directional. When the speakers or sound units of the speakers are directed in a certain direction, the sound energy in that direction will be more concentrated. This is determined by the physical properties of sound, which causes the sound on one side of the speaker sound unit to sound louder. This requires the installation of multiple sets of speakers to achieve this. When installing multiple sets of speakers, complex debugging and calibration work is required to ensure that the sound is evenly distributed and accurately propagated in space. In addition, as the number of speakers increases, the work of daily maintenance and care will also increase accordingly, including checking the lines, replacing damaged parts, etc. In complex environments with a large flow of people, the complex line distribution may become a safety hazard. If the line layout is unreasonable or improperly maintained, it may cause safety accidents such as tripping and electric shock. Utility Model Content

[0004] The purpose of the present invention is to provide a double-row matrix speaker system to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A double-row matrix speaker system, comprising:

[0007] A support base, wherein a sound body is provided above each of the support bases, wherein a connecting piece 1 is provided on the rear side of one of the sound bodies, and a connecting piece 2 is provided on the rear side of the other sound body, wherein the connecting piece 1 and the connecting piece 2 are concentrically connected after being penetrated by a rotating shaft;

[0008] The limiting components are installed below the support seat and are used to relatively fix the position of the audio body after opening and closing.

[0009] Preferably, universal wheels for movement are provided under the support base, and the first connector and the second connector are respectively located above and below the two audio bodies.

[0010] Preferably, the limiting assembly includes a fixed shaft 1 and a fixed shaft 2, and the fixed shaft 1 and the fixed shaft 2 are respectively arranged below the support seat.

[0011] Preferably, the outer surface of the fixed shaft 1 is rotatably connected to a connecting bar, the interior of the connecting bar is set to be in a hollow state, and the connecting bar is provided with an A end and a B end.

[0012] Preferably, a limiting groove is provided between the A end and the B end, and the limiting groove is divided into two sections, which are a horizontal and vertical section and a curved serrated section.

[0013] Preferably, the horizontal and vertical sections of the limiting grooves close to the A end are both provided with extrusion blocks 1, and the curved serrations of the limiting grooves close to the B end are both provided with extrusion blocks 2.

[0014] Preferably, the outer surface of the second fixed shaft is rotatably connected to a pull-out strip, and the outer surface of the pull-out strip is slidably located in the connecting strip.

[0015] Preferably, the side walls of the pull-out strips close to the limiting grooves are each provided with a connecting shaft, and the outer surfaces of the connecting shafts are each provided with a rotating block.

[0016] Preferably, a limiting rod is provided through both sides of the two rotating blocks away from the connecting shaft, and the diameter of the limiting rod is adapted to the curved serrated groove surface of the limiting groove.

[0017] Preferably, a slot is provided on the outer surface of the rotating block, a side of the rotating block close to the slot is provided as an inclined surface, and the side walls of the pull-out strip close to the limiting slot are provided with connecting pins, and the connecting pins are provided with elastic paddles.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This double-row matrix speaker system uses a limiting component to enable the angle between the speaker bodies to be freely adjusted according to usage. Depending on the specific usage scenario, users can adjust the angle between the speaker bodies to change the directionality of the sound. This is crucial for scenarios where the direction of sound propagation needs to be precisely controlled to ensure that the sound can accurately cover the target area. By changing the sound direction of the speaker body and adjusting the angle reasonably, the sound propagation path can be optimized, and the loss and interference of the sound during the propagation process can be reduced, thereby improving the sound quality. Whether it is necessary to cover a large area or concentrate the sound, it can be achieved by adjusting the angle. Users can freely adjust the angle and position of the speakers according to their preferences and hearing needs. When the angle between the speaker bodies is appropriate, a wider and more three-dimensional sound field effect can be created, allowing the audience to experience a more realistic and immersive audio experience.

[0020] This dual-row matrix speaker system utilizes connectors 1 and 2, working in conjunction with a stopper assembly, to increase and secure the angle between the speaker bodies, maintaining a relatively fixed position. The combination of connectors and stoppers effectively secures the speaker bodies, minimizing movement and offset due to vibration or external forces. This stability not only ensures the long-term reliability of the system but also prevents degradation in sound quality due to positional changes. Furthermore, the slots and extrusion blocks 1 and 2 allow the speaker bodies to adjust their angles while also fitting snugly together for easy transport and storage.

[0030] The present invention is described in further detail below with reference to the accompanying drawings.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0033] It is understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0034] See also Figure 1-Figure 7 , a double-row matrix speaker sound system, comprising:

[0035] The support base 1 has a speaker body 101 disposed above each support base 1. A connector 102 is disposed on the rear side of one speaker body 101, and a connector 203 is disposed on the rear side of the other speaker body 101. The connectors 102 and 103 are connected concentrically by a rotating shaft 104. A position limiting assembly is mounted below the support base 1 to maintain the relative position of the speaker bodies 101 after opening and closing. Universal wheels are disposed below the support base 1 for movement. The connectors 102 and 103 are located above and below the two speaker bodies 101, respectively.

[0036] The universal wheels at the bottom of the support base 1 allow the speaker body 101 to be easily moved to a desired position, improving ease of use. After the speaker body 101 is moved to a certain position, an opposing force is applied to open the speaker body 101. At this time, the first and second connectors 102 and 103 rotate under the restraining force of the rotating shaft 104, causing the angle between the two speaker bodies 101 to gradually increase, thereby flexibly adjusting the sound direction of the speaker body 101 and adapting it to different usage scenarios and needs. When the speaker body 101 stops rotating, the bottom limiter assembly relatively fixes the position of the speaker body 101, preventing unnecessary movement or shaking due to external forces or vibrations during use, thereby ensuring the stability and sound quality of the speaker. At the same time, the change in the angle between the speaker bodies 101 causes the sound direction of the speaker bodies 101 to change, which can expand the range and depth of the sound field. When the angle between the speaker bodies 101 is appropriate, a wider and more three-dimensional sound field effect can be created, giving the listener a more realistic and immersive audio experience.

[0037] Further examples:

[0038] See also Figure 4-Figure 7 , a double-row matrix speaker sound,

[0039] The limiting assembly includes a fixed shaft 1 2 and a fixed shaft 2 201, respectively disposed below the support base 1. A connecting bar 3 is rotatably connected to the outer surface of the fixed shaft 1. The interior of the connecting bar 3 is hollow and has an A end 301 and a B end 302. A limiting slot 303 is provided between the A end 301 and the B end 302. The limiting slot 303 is divided into two sections: a horizontal and vertical section and a curved serrated section. A pull-out bar 4 is rotatably connected to the outer surface of the fixed shaft 2 201. The outer surface of the pull-out bar 4 slides within the connecting bar 3. The sidewalls of the pull-out bar 4 near the limiting slot 303 are each provided with a connecting shaft 401. The outer surface of each connecting shaft 401 is provided with a rotating block 402. A limiting rod 403 is provided on the side of the two rotating blocks 402 away from the connecting shaft 401. The diameter of the limiting rod 403 matches the curved serrated surface of the limiting slot 303.

[0040] The limiting groove 303 provided on the outer surface of the fixed shaft 1 2 limits the limiting rod 403 provided on the fixed shaft 2 201, so that the speaker bodies 101 can be relatively fixed in position when they are opened to a certain angle. When one speaker body 101 is pulled to increase the angle between it and the other speaker body 101, the pull-out strip 4 moves from the A end 301 of the connecting strip 3 to the B end 302 of the pull-out strip 4. At this time, the limiting rod 403 is engaged with the curved sawtooth groove of the limiting groove 303. When the speaker body 101 is further moved, the limiting rod 403 moves from the curved sawtooth groove surface of the limiting groove 303 to the next sawtooth groove, thereby limiting the limiting rod 403 and keeping the speaker bodies 101 relatively fixed in position. The angle between the speaker bodies 101 can be adjusted according to practical needs. Reasonable angle adjustment can optimize the sound propagation path, reduce sound loss and interference during propagation, and thus improve sound quality. This is particularly important in applications where clarity and timbre must be maintained. Whether you need to cover a wide area or focus the sound, you can achieve this by adjusting the angle. Users can freely adjust the angle and position of the speakers according to their preferences and hearing needs.

[0041] Further examples:

[0042] See also Figure 5-Figure 7 , a double-row matrix speaker sound,

[0043] The horizontal and vertical sections of the limit slot 303 near end A 301 are each provided with an extrusion block 1 304, and the curved serrated side of the limit slot 303 near end B 302 is each provided with an extrusion block 2 305. The outer surfaces of both extrusion blocks 1 304 and 305 are curved. The outer surface of the rotating block 402 is provided with a latching slot 404, and the side of the rotating block 402 near the latching slot 404 is provided with an inclined surface. The sidewalls of the pull-out strip 4 near the limit slot 303 are each provided with a connecting pin 405, each of which is provided with an elastic paddle 406.

[0044] When the device is finished using, the speaker body 101 is moved to the maximum angle. At this time, the brick of the pull-out strip 4 drives the limit rod 403 to gradually approach the extrusion block 2 305 of the connecting strip 3B end 302. The curved surface setting of the extrusion block 2 305 prompts it to squeeze the limit rod 403, thereby causing the elastic pick 406 of the connecting pin 405 to be lifted by the inclined surface of the rotating block 402. When it moves to the position of the card slot 404, the restriction of the inclined surface of the rotating block 402 is lost, and the elastic pick 406 is stuck in the card slot 404. At this time, the limit rod 403 is in the elastic pick 40 6, the horizontal and vertical sections of the limit groove 303 are fitted together under the limiting action of 6. At this time, the speaker body 101 is pushed towards each other, causing the angle between the two to gradually decrease until the two support bases 1 are fitted together. At the same time, the pull-out strip 4 approaches the A end 301 of the connecting strip 3, and the extrusion block 1 304 set at the A end 301 squeezes the limit rod 403, so that the elastic pick 406 is separated from the card slot 404. At this time, the limit rod 403 is fitted into the jagged side of the limit groove 303, and the floor space occupied by the speaker body 101 is reduced after folding, which is convenient for storage and transportation.
