Description

Technical Field

[0001] This utility model relates to the field of audio stacking technology, and in particular to an audio stacking mechanism. Background Technology

[0002] The sound system is designed to provide high-quality music sound effects. On the performance platform of an outdoor concert, a subwoofer is usually set up as the main sound unit. In order to improve the high-quality music sound effects on site, while not taking up too much space on the performance platform, multiple speakers are usually stacked vertically.

[0003] Since the main body of the stacked speakers is usually set on the edge of the performance platform, very close to the audience, a protective net is usually installed on the vertical stacking mechanism of the speakers to prevent them from being damaged by hard objects.

[0004] In outdoor settings, strong winds may occur. Since the speakers are stacked vertically and are quite tall, a windproof structure needs to be installed on the stacking mechanism. However, the existing stacking mechanism only uses the weight of sandbags for wind protection. The sandbags are prone to slipping, which affects the wind resistance and stability, and greatly reduces the overall wind resistance and stability of the vertical stacking mechanism of the speakers.

[0005] To address this, we designed a vertical stacking mechanism for speakers to meet the needs of practical applications. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a sound stacking mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a speaker stacking mechanism, including a stacking windproof frame, a performance platform below the stacking windproof frame, a steel base frame at the lower end of the performance platform, a screw groove on the steel base frame, a windproof inlet on the performance platform, stacked speaker bodies on the performance platform, a finger-grip groove on the stacked speaker bodies, a side slot within the finger-grip groove, a fixed plate and a top insert block on the stacking windproof frame, a motor on the fixed plate, a double-threaded screw on the motor shaft of the motor, a guide groove on the stacking windproof frame, a stacking side plate slidingly connected within the guide groove, and a side insert post on the stacking side plate; The stacked windproof frame is provided with a windproof side frame, the windproof side frame is provided with a first top rib and a second top rib, and the stacked windproof frame is provided with a screw rod; The stacked speaker body is provided with a bottom insert and a top slot, the stacked windproof frame is provided with a storage battery, and the storage battery is provided with a switch.

[0008] In detail, the top of the stacked side plate is provided with a limiting plate and its lower end is in sliding contact with the upper surface of the stacked windproof frame.

[0009] In detail, the stacked side plates are two symmetrical plates, each threaded with a double-threaded screw. There is a gap between the lower end of the stacked side plates and the performance platform. The side inserts are located on the inner wall of the stacked side plates.

[0010] In detail, the windproof side frame consists of two symmetrical sets, each set consisting of two symmetrical sets, and the windproof side frame as a whole has a bent structure and passes vertically through the windproof socket.

[0011] In detail, both the first and second top ribs are triangular in shape.

[0012] In detail, the side slot is opened in the finger buckle groove and is horizontally aligned with the side insertion post, and the guide groove is a rectangular vertical through-hole that slides and guides the stacked side plates.

[0013] In detail, the lower corner of the top insert block is provided with an arc-shaped chamfer, the screw rod passes laterally through the windproof side frame, and the screw rod is provided with a diamond-shaped pin cap.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application: This utility model features a stacked windproof frame with a double-screw drive structure, symmetrically arranged stacked side plates with side inserts on the stacked windproof frame, a windproof side frame structure with a first top rib and a second top rib, and a screw rod structure. Additionally, a side slot is provided within the finger groove of the stacked speaker body. First, the speakers are vertically stacked to form the main structure of the stacked speakers. Then, the stacked windproof frame is placed on top of the main stacked speakers. At this time, the windproof side frames on both sides pass through the performance platform and are threaded and locked by screws. Then, the motor is started to drive the double screw to rotate, which in turn drives the stacked side plates on both sides to move towards each other and lock into the corresponding side slots. At the same time, the bottom of the first top rib and the second top rib are also stably supported by the performance platform, which improves the wind resistance and stability of the vertical stacking mechanism of the speakers.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-6 A sound stacking mechanism includes a stacking windproof frame 1, a performance platform 2 below the stacking windproof frame 1, a steel base frame 3 at the lower end of the performance platform 2, a screw groove 31 on the steel base frame 3, a windproof inlet 21 on the performance platform 2, a stacked sound body 4 on the performance platform 2, a finger-loop groove 43 on the stacked sound body 4, a side slot 44 in the finger-loop groove 43, a fixed plate 7 and a top insert block 12 on the stacking windproof frame 1, a motor 71 on the fixed plate 7, a double-threaded screw 62 on the motor shaft of the motor 71, a guide groove 11 on the stacking windproof frame 1, a stacking side plate 6 slidably connected in the guide groove 11, and a side insert post 61 on the stacking side plate 6. The stacked windproof frame 1 is provided with a windproof side frame 5, the windproof side frame 5 is provided with a first top rib plate 51 and a second top rib plate 52, and the stacked windproof frame 1 is provided with a screw rod 8. The stacked speaker body 4 is provided with a bottom insert block 41 and a top slot 42. The stacked windproof frame 1 is provided with a storage battery 9. The storage battery 9 is provided with a switch 91. The storage battery 9 is existing technology and can provide power to the motor 71. The upper end of the switch 91 has three buttons that control the forward rotation, stop, and reverse rotation of the motor shaft of the motor 71, respectively.

[0019] The stacked speaker body 4 is a conventional technology, consisting of three subwoofer speakers commonly used outdoors, stacked vertically. Expansion bolts are pre-embedded in the ground below the steel base frame 3, and the bottom of the steel base frame 3 is securely installed to the ground through the expansion bolts.

[0020] It should be further explained that the top of the stacked side plate 6 is provided with a limiting plate 63 and its lower end is in sliding contact with the upper end surface of the stacked windproof frame 1. When the stacked side plate 6 moves horizontally, the lower end of the limiting plate 63 will slide along the upper end surface of the stacked windproof frame 1 to prevent the stacked side plate 6 from sliding down and rotating.

[0021] It should be further explained that there are two stacked side plates 6 that are symmetrical on the left and right and are threaded to the double screws 62 respectively. The double screws 62 are forward and reverse threaded rods and are threaded to the pre-set threaded holes on the stacked side plates 6 on both sides. When the double screws 62 rotate forward and reverse, the stacked side plates 6 on both sides can move closer or further away at the same time.

[0022] There is a gap between the lower end of the stacked side panel 6 and the performance platform 2 to prevent the stacked side panel 6 from rubbing against the performance platform 2 when it moves horizontally.

[0023] Side inserts 61 are provided on the inner wall of the stacked side plate 6. When each side insert 61 is inserted into the side slot 44, it ensures that the side of the stacked speaker body 4 is squeezed and positioned.

[0024] It should be further explained that the windproof side frame 5 consists of two symmetrical sets, each set consisting of two symmetrical sets. The windproof side frame 5 has a bent structure and passes vertically through the windproof socket 21. After the windproof side frames 5 on both sides pass through the windproof socket 21 and are threadedly locked to the screw groove 31 by the screw rod 8, the steel base frame 3 is securely installed and fixed to the entire performance platform 2 by multiple bolts. This achieves the integration of the windproof side frame 5, the stacked speaker body 4 that is pressed down, the steel base frame 3, and the performance platform 2 into a whole, ensuring wind resistance.

[0025] It should be further noted that the first top rib plate 51 and the second top rib plate 52 are both triangular structures. The first top rib plate 51 and the second top rib plate 52 are both made of 12Cr1MoV alloy steel, which has high strength and is easy to weld and process. In addition, the triangular structure has high stability. When they are in stable contact with the upper surface of the performance platform 2, the overall wind resistance and windproof stability of the vertical stacking mechanism of the sound system is improved.

[0026] It should be further noted that the side slot 44 is opened in the finger slot 43 and is horizontally aligned with the side plug 61, which ensures that the side plug 61 is electrically inserted into the side slot 44 later, further improving the stacking stability of the stacked speaker body 4.

[0027] The guide groove 11 is a rectangular vertical through-hole and slides with the stacked side plate 6. Combined with the rotation of the double screw 62, the stacked side plate 6 is horizontally guided and slid in the guide groove 11.

[0028] It should be further noted that the lower corner of the top insert block 12 is provided with an arc-shaped chamfer 13, which improves the smoothness of the insertion of the top insert block 12 into the top slot 42.

[0029] The screw rod 8 passes horizontally through the windproof side frame 5. There is a pre-set through hole on the windproof side frame 5. The screw rod 8 can pass through and rotate in the pre-set through hole. At the same time, the screw rod 8 can be easily pulled out and removed from the windproof side frame 5.

[0030] The screw 8 is equipped with a diamond-shaped pin cap 81, which can be directly turned by hand, making operation very convenient.

[0031] Operating procedure: First, vertically stack the speaker units 4 by connecting the matching bottom inserts 41 and top slots 42. Next, horizontally remove the screws 8 from the windproof side brackets 5. Then, install the stacked windproof brackets 1 on top of the stacked speaker units 4, ensuring that the top inserts 12 are inserted into the corresponding top slots 42 on the topmost stacked speaker unit 4. At this point, the four windproof side brackets 5 will also vertically pass through the windproof insertion ports 21. Next, press the button on switch 91. Battery 9 supplies power to motor 71, which drives the double-threaded screw 62 to rotate forward via the motor shaft of motor 71. At this time, the stacked side plates 6 on both sides slide towards each other along the guide groove 11 through the threaded transmission between them and the double-threaded screw 62. When the side inserts 61 on the stacked side plates 6 are all inserted into the side slots 44 on both sides of the stacked speaker body 4, motor 71 is stopped. Next, insert the four removed screws 8 horizontally through the windproof side frame 5, and then rotate the pin cap 81 clockwise to rotate the screws 8 clockwise and lock them into the screw groove 31 on the steel base frame 3. This will allow the stacked windproof frame 1 to be stably installed on the stacked speaker body 4. At the same time, the bottom of the first top rib plate 51 and the second top rib plate 52 will also be stably supported against the upper surface of the performance platform 2, which improves the wind resistance and stability of the vertical stacking mechanism of the sound system.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
