DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figures 1 to 9 As shown, a hanging speaker according to an embodiment of the present invention comprises: a substrate 1; a first mounting seat 2, which is arranged directly below the substrate 1 and connected via a fixing mechanism; a second mounting seat 3, which is arranged directly below the first mounting seat 2 and connected via a rotating mechanism; a speaker body 5, wherein the two side walls of the speaker body 5 are rotatably connected to the second mounting seat 3 via a rotating shaft 36; a fixing frame 4, wherein the fixing frame 4 is fixedly connected to the outer side wall of the bottom end of the speaker body 5; a dustproof mechanism, which is arranged on the fixing frame 4; the dustproof mechanism comprises two protective plates 41 rotatably connected to the fixing frame 4 via a rotating shaft, and a folded cloth 42 is fixedly connected between two adjacent side walls of the two protective plates 41; one end of the rotating shaft is A second gear 43 is fixedly connected; two side panels 46 are fixedly connected to the side wall of the speaker body 5; a bidirectional ball screw 48 is rotatably connected between the two side panels 46 through a bearing; two movable plates 47 are symmetrically threadedly connected to the bidirectional ball screw 48; the bottom of each movable plate 47 is fixedly connected to a second rack 44, and the second rack 44 is meshed with the second gear 43 at the bottom; a second motor 45 is fixedly connected to one of the side panels 46, and the output shaft of the second motor 45 is fixedly connected to one end of the bidirectional ball screw 48; the speaker body 5 includes a heat dissipation mechanism and a speaker; a dustproof net is fixedly connected to the outer wall of the heat dissipation mechanism; the speaker is arranged on the inner side of the protective plate 41.

[0042] In the prior art, the connecting seat and the connecting rod can be quickly disassembled and assembled by using mutually perpendicular perforations and positioning grooves, and the requirements for floor use can also be met. However, the speaker body 5 is suspended at a high place, and the dust flying on the ground easily enters the speaker body 5, which is inconvenient to clean in time. The dust generates magnetic wave resonance in the speaker body 5, thereby affecting the sound quality of the speaker body 5. In addition, the dust accumulates in the speaker body 5 and blocks the heat dissipation holes of the speaker body 5, affecting the heat dissipation. A lot of heat is accumulated in the speaker body 5, which damages the service life of the speaker body 5.

[0043] When the dustproof mechanism provided by the present invention is in use, when the speaker body 5 is not working, the protective plate 41 is closed, and the folded cloth 42 is folded along with the protective plate 41 to shield and protect the speaker to prevent dust from entering; when the speaker body 5 is working, the protective plate 41 is opened, and the folded cloth 42 is opened along with the protective plate 41, and together with the protective plate 41, it forms a trumpet shape with a small top and a large bottom, so as to aggregate the sound emitted by the speaker, reduce the sound dispersion, and facilitate the sound propagation;

[0044] During the opening and closing process of the protective plate 41, the second motor 45 is turned on, and the second motor 45 drives the bidirectional ball screw 48 to rotate through the output shaft. A ball nut seat is provided at the connection between the bidirectional ball screw 48 and the movable plate 47, and the radial movement of the movable plate 47 is guaranteed by the ball nut seat, so that the bidirectional ball screw 48 drives the movable plate 47 to move in opposite directions, and drives the second rack 44 to move in opposite directions through the movable plate 47, drives the second gear 43 to rotate in opposite directions through the second rack 44, drives the rotating shaft to rotate in opposite directions through the second gear 43, and drives the protective plate 41 to rotate in opposite directions through the rotating shaft, thereby realizing the opening and closing function of the protective plate 41, thereby realizing the dustproof and protective effect on the speaker body 5.

[0045] As shown in the figure and Figure 6 As shown, an L-shaped plate 31 is fixedly connected to the side wall of the second mounting seat 3; a first motor 32 is fixedly connected to the inner side wall of the L-shaped plate 31, and a rotating rod 33 is fixedly connected to the output shaft of the first motor 32; a swing rod 34 is fixedly connected to the outer side wall of the rotating shaft 36; one end of the swing rod 34 close to the rotating shaft 36 is rotatably connected to the second mounting seat 3 through a pin shaft; a sliding opening 35 is formed at one end of the swing rod 34 away from the rotating shaft 36, and one end of the rotating rod 33 is slidably connected in the sliding opening 35 through a sliding column.

[0046] The swing rod 34 provided by the present invention is used to drive the swing of the speaker body 5 when in use. By turning on the first motor 32, the first motor 32 drives the rotating rod 33 to rotate through the output shaft, and the rotating rod 33 drives the sliding column to rotate. At the same time, the sliding column slides in the sliding opening 35, and the sliding column presses the swing rod 34, thereby driving the swing rod 34 to swing back and forth around the pin shaft. The rotating shaft 36 is driven to rotate through the swing rod 34, and the speaker body 5 is driven to rotate through the rotating shaft 36, so that the angle of the speaker body 5 in the front and rear directions can be adjusted, thereby expanding the use range of the speaker body 5.

[0047] like Figure 6 As shown, an angle sensor 37 is fixedly connected to the outer wall of the rotating shaft 36 , and the angle sensor 37 is electrically connected to the first motor 32 .

[0048] The angle sensor 37 provided by the present invention is used to detect angles when in use. By setting the front and rear rotation angles of the speaker body 5 in a computer program, the rotation of the first motor 32 is controlled by the computer program. During the rotation process, the rotation angle of the rotating shaft 36 is detected by the angle sensor 37 to monitor the working state of the speaker body 5. When the rotating shaft 36 is loose or stuck, or the sliding column is worn and the sliding opening 35 does not fit well, the rotation angle of the rotating shaft 36 deviates, which is detected by the angle sensor 37 and the signal is transmitted to the computer program for alarm, thereby improving the accuracy of the rotation of the speaker body 5.

[0049] like Figure 7 As shown, the rotating mechanism includes a rotating frame 24 fixedly connected to the top of the second mounting seat 3; both ends of the rotating frame 24 are fixedly connected to the inner wall of the first mounting seat 2; a first gear 23 is fixedly connected to the outer side of the rotating frame 24, an electric push rod 21 is fixedly connected to the top of the second mounting seat 3, and a first rack 22 is fixedly connected to the output end of the electric push rod 21, and the first gear 23 is meshed with the first rack 22.

[0050] When the first gear 23 and the first rack 22 provided by the present invention are in use, by turning on the electric push rod 21, the electric push rod 21 drives the first rack 22 to move through the output end. Since the first rack 22 and the first gear 23 are meshed with each other, the first rack 22 rotates around the first gear 23 when it moves. When the first rack 22 rotates, the electric push rod 21 and the second mounting seat 3 also rotate. When the second mounting seat 3 rotates, it drives the rotating frame 24 to rotate around the rotating shaft, so that the second mounting seat 3 swings left and right.

[0051] like Figure 5 As shown, an infrared sensor 25 is fixedly connected to the top inner wall of the first mounting seat 2 , and the infrared sensor 25 is electrically connected to the electric push rod 21 .

[0052] When the infrared sensor 25 provided by the present invention is used, the left and right rotation angles of the speaker body 5 are set in the computer program, thereby controlling the rotation of the electric push rod 21 through the computer program. During the rotation process, when the first rack 22 rotates around the first gear 23, the rotation angle of the first rack 22 is detected by the infrared sensor 25. When the first rack 22 and the first gear 23 are worn and poorly matched, resulting in inaccurate angle adjustment, the rotation state of the first rack 22 is detected by the infrared sensor 25. When a problem occurs, the signal is transmitted to the computer program through the infrared sensor 25, and an alarm is sounded to remind the staff to repair, thereby improving the accuracy of the rotation of the speaker body 5.

[0053] like Figure 7 and Figure 8 As shown, the fixing mechanism includes two fixing plates 15 fixedly connected to the bottom of the base plate 1, a reciprocating screw 16 is rotatably connected between the two fixing plates 15 via a bearing, one end of the reciprocating screw 16 is threadedly connected to a first plug block 13, and the other end of the reciprocating screw 16 is rotatably connected to a second plug block 14 via a bearing; slots 26 are provided on both side walls of the first mounting seat 2; the first plug block 13 and the second plug block 14 are respectively matched with the slots 26; one end of the reciprocating screw 16 is fixedly connected to a rotary block 18.

[0054] The present invention provides a first plug block 13 and a second plug block 14 for fixing the first mounting seat 2 when in use. During installation, a side slot 26 of the first mounting seat 2 is inserted into the second plug block 14, and then the rotary block 18 is rotated, and the reciprocating screw rod 16 is driven to rotate by the rotary block 18, and the first plug block 13 is driven to move by the reciprocating screw rod 16, and the first plug block 13 moves to another slot 26 of the first mounting seat 2, thereby fixing the first mounting seat 2 and the speaker body 5, and realizing the function of quickly installing the speaker body 5.

[0055] like Fig. 9 As shown, four grooves are opened on the top of the substrate 1 , and suction nozzles 11 are installed in each of the grooves. The suction nozzles 11 are respectively arranged at the four corners of the substrate 1 .

[0056] When the suction nozzle 11 provided by the present invention is in use, when the speaker body 5 needs to be hung on the ceiling, the ceiling is easily aesthetically pleasing by fixing the substrate 1 by punching holes in the ceiling. The suction nozzle 11 is needed to fix the entire device of the substrate 1 and the speaker body 5 on the ceiling by suction. Since the ceiling is smooth enough, the suction nozzle 11 is convenient for adsorption.

[0057] like Fig. 9 As shown, positioning holes 12 are respectively formed at the four corners of the base plate 1 , and threaded bolts are inserted into the positioning holes 12 .

[0058] When the positioning hole 12 provided by the present invention is in use, when the speaker body 5 needs to be hung in a music shed or other sheds, the top of the shed may be made of wood or steel, and the direct adsorption effect is not good. If the speaker body 5 falls, there is a safety hazard; the substrate 1 is fixed to the top of the shed by inserting a threaded bolt into the positioning hole 12 to achieve fixation.

[0059] like Figure 3 As shown, two cross bars 49 are fixedly connected between the two side plates 46 , and the movable plates 47 are all slidably connected to the cross bars 49 .

[0060] When the cross bar 49 provided by the present invention is in use, the movable plate 47 slides on the cross bar 49 during the movement, and the cross bar 49 limits the movable plate 47 in the horizontal direction.

[0061] like Figure 8 As shown, two guide rods 17 are fixedly connected between the two fixing plates 15 ; the first plug block 13 is slidably connected to the two guide rods 17 , and the second plug block 14 is fixedly connected to the two guide rods 17 .

[0062] When the guide rod 17 provided by the present invention is in use, the second plug block 14 slides on the guide rod 17 during the movement of the second plug block 14, and the guide rod 17 limits the second plug block 14 in the horizontal direction.

[0063] Working away from dust: When the dust-proof mechanism provided by the present invention is in use, when the speaker body 5 is not working, the protective plate 41 is closed, and the folding cloth 42 is folded along with the protective plate 41 to shield and protect the speaker to prevent dust from entering; when the speaker body 5 is working, the protective plate 41 is opened, and the folding cloth 42 is opened along with the protective plate 41, and together with the protective plate 41, it forms a trumpet shape with a small top and a large bottom, which aggregates the sound emitted by the speaker, reduces the sound dispersion, and facilitates the sound propagation;

[0064] When the protective plate 41 is opened and closed, the second motor 45 is turned on, and the second motor 45 drives the bidirectional ball screw 48 to rotate through the output shaft. A ball nut seat is provided at the connection between the bidirectional ball screw 48 and the movable plate 47, and the radial movement of the movable plate 47 is ensured by the ball nut seat, so that the bidirectional ball screw 48 drives the movable plate 47 to move in opposite directions, and the second rack 44 is driven to move in opposite directions through the movable plate 47, and the second gear 43 is driven to rotate in opposite directions through the second rack 44, and the rotating shaft is driven to rotate in opposite directions through the second gear 43, and the protective plate 41 is driven to rotate in opposite directions through the rotating shaft, so as to realize the opening and closing functions of the protective plate 41, thereby realizing the dustproof and protective effects on the speaker body 5;

[0065] By turning on the first motor 32, the first motor 32 drives the rotating rod 33 to rotate through the output shaft, and the rotating rod 33 drives the sliding column to rotate. At the same time, the sliding column slides in the sliding opening 35, and the sliding column presses the swing rod 34, thereby driving the swing rod 34 to swing back and forth around the pin shaft, and the rotating shaft 36 is driven to rotate through the swing rod 34, and the speaker body 5 is driven to rotate through the rotating shaft 36, so that the angle of the speaker body 5 in the front and rear directions is adjusted, and the use range of the speaker body 5 is expanded; the front and rear rotation angles of the speaker body 5 are set in the computer program, so that the rotation of the first motor 32 is controlled by the computer program. During the rotation process, the rotation angle of the rotating shaft 36 is detected by the angle sensor 37 to monitor the working state of the speaker body 5. When the rotating shaft 36 is loose or stuck, or the sliding column is worn and the sliding opening 35 does not match well, the rotation angle of the rotating shaft 36 deviates, which is detected by the angle sensor 37, and the signal is transmitted to the computer program for alarm, thereby improving the accuracy of the rotation of the speaker body 5;

[0066] By turning on the electric push rod 21, the electric push rod 21 drives the first rack 22 to move through the output end. Since the first rack 22 and the first gear 23 are meshed with each other, the first rack 22 rotates around the first gear 23 when it moves. When the first rack 22 rotates, the electric push rod 21 and the second mounting seat 3 also rotate. When the second mounting seat 3 rotates, the rotating frame 24 is driven to rotate around the rotating shaft, so that the second mounting seat 3 swings left and right; the left and right rotation angles of the speaker body 5 are set in the computer program, so that the rotation of the electric push rod 21 is controlled by the computer program. During the rotation process, when the first rack 22 rotates around the first gear 23, the rotation angle of the first rack 22 is detected by the infrared sensor 25. When the first rack 22 and the first gear 23 are worn and poorly matched, resulting in inaccurate angle adjustment, the rotation state of the first rack 22 is detected by the infrared sensor 25. When a problem occurs, the infrared sensor 25 transmits a signal to the computer program, and an alarm is triggered to remind the staff to repair, thereby improving the accuracy of the rotation of the speaker body 5;

[0067] During installation, the slot 26 on one side of the first mounting seat 2 is inserted into the second plug block 14, and then the rotary block 18 is rotated, and the reciprocating screw rod 16 is driven to rotate by the rotary block 18, and the first plug block 13 is driven to move by the reciprocating screw rod 16, and the first plug block 13 moves to the other slot 26 of the first mounting seat 2, thereby fixing the first mounting seat 2 and the speaker body 5, and realizing the function of quickly installing the speaker body 5;

[0068] When the speaker body 5 needs to be hung on the ceiling, the ceiling is easily aesthetically pleasing if the base plate 1 is fixed by punching holes in the ceiling. The suction nozzle 11 is needed to fix the entire device of the base plate 1 and the speaker body 5 on the ceiling by suction. Since the ceiling is smooth enough, it is convenient for the suction of the suction nozzle 11. When the speaker body 5 needs to be hung in a music shed or other sheds, the top of the shed may be made of wood or steel, and the direct suction effect is not good. If the speaker body 5 falls, there is a safety hazard. The base plate 1 is fixed to the top of the shed by inserting a threaded bolt into the positioning hole 12 to achieve fixation.
