Description

Technical Field

[0001] The invention belongs to the field of speakers, in particular to a combined floor-standing speaker. Background Art

[0002] Since most of the speakers adopt the bass reflex box design, we focus on the bass reflex box type speakers to facilitate our understanding of the working principles of speakers. The bass reflex box type speakers are designed based on the Helmholtz resonance principle in acoustics. Most of the existing floor-standing speakers on the market use bass reflex tubes, which can obtain better bass response, but most of the floor-standing speakers are large and bulky.

[0003] In the prior art, combined floor-standing speakers are basically not used in homes due to their size and weight, but are mostly used in entertainment venues. Such speakers are too heavy to be carried, so when cleaning some places, the bottom of the speakers can easily become a sanitary dead corner, causing garbage accumulation.

[0004] To this end: the present invention provides a combined floor-standing speaker. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a combined floor-standing speaker described in the present invention is characterized in that it includes a shell, a dustproof mechanism is arranged on the outside of the shell, a lifting mechanism is arranged on the inside of the shell, and a moving component is arranged on the bottom of the shell;

[0007] The outer wall of the shell is provided with a plurality of speakers, the outer wall of the shell is provided with a lifting button and a moving switch, the outer wall of the shell is provided with a heat dissipation port, the inner wall of the moving switch is fixedly connected with a limiting column, and the outer walls of the shell are slidably connected with side plates on both sides;

[0008] The shell is the outer shell of the combined floor-standing speaker. The dust-proof mechanism is used to prevent dust in the air from entering the shell through the speaker. The lifting mechanism is used to control the lifting of the side panels on both sides of the shell, which is convenient for cleaning the inside of the speaker and preventing dust accumulation. The moving component is used to control the movement of the speaker. When the speaker is in use, the sound source is transmitted from the speaker and the air flow rate inside the shell is accelerated through the heat dissipation port, thereby achieving the effect of cooling the inside of the shell. Pressing the lifting button can control the shell to rise away from the ground, which is convenient for cleaning the bottom. Toggling the moving switch can control the movement of the trolley. Through the control of the moving component and the lifting mechanism, the movement of the shell is controlled. Manual handling and movement are no longer required, and it is easier to operate and use the floor-standing speakers.

[0009] Preferably, the dust-proof mechanism includes a dust-proof cover. A dust-proof groove is formed in the outer wall of the housing. The outer wall of the dust-proof cover is inserted into and in contact with the inner wall of the dust-proof groove. A fixing column is fixedly installed on the inner wall of the dust-proof cover. One end of the fixing column is rotatably connected to an adjusting rod. The dust-proof mechanism is used to prevent external dust from entering the housing, so as to prevent dust from entering the interior of the housing and increasing the burden on the operation of the device. Since the adjusting rod is in the shape of a disc with a semi-circular end and the remaining part is in the shape of a rack on one side, when the speaker is not in use, one end of the adjusting rod rotates under control, thereby controlling the dust-proof cover to rotate along a fixed arc trajectory to the front of the speaker. Subsequently, the rack part of the adjusting rod is controlled to slide the dust-proof cover linearly into the interior of the dust-proof groove, covering the position of the speaker. By means of the adjusting rod, the dust-proof cover is controlled to cover the speaker, achieving the effect of preventing dust from entering the interior of the housing.

[0010] Preferably, an adjusting slide rail is provided on the inner wall of the dust-proof groove. The adjusting rod is slidably connected to the adjusting slide rail. An adjusting gear is arranged inside the dust-proof groove. The teeth of the adjusting gear are meshed with the teeth of the adjusting rod. A connecting member is arranged between the outer walls of the dust-proof covers. By controlling the rotation of the adjusting gear, the adjusting gear is meshed with the semi-circular gear of the adjusting rod, controlling one end of the adjusting rod to deflect along a predetermined trajectory to the front of the speaker. Subsequently, since the teeth of the adjusting rod are meshed with the teeth inside the adjusting slide rail, the adjusting rod slides linearly inward along the adjusting slide rail and retracts into the interior of the adjusting slide rail. When one dust-proof cover is controlled to move along a fixed arc and retract into the dust-proof groove, the other dust-proof covers are all controlled to retract into the interior of the dust-proof groove due to the connecting member. If the speaker needs to be used, just perform the opposite operation to the above. Through the cooperation of the adjusting slide rail and the adjusting rod, the effect of controlling the opening and closing of the dust-proof cover is achieved.

[0011] Preferably, a screw rod is fixedly connected to the outer wall of the adjusting gear. The other end of the screw rod is threadedly connected to a control member. When wanting to open the dust-proof cover, just press the control member. The control member moves downward and drives the screw rod to rotate through screw thread transmission. The screw rod drives the adjusting gear to rotate. When wanting to close the dust-proof cover, just pull up the control member. At this time, the adjusting gear will rotate in the reverse direction. By means of the control member, the effect of controlling the closing or opening of the dust-proof cover is achieved.

[0012] Preferably, the lifting mechanism includes a central column. One end of the central column is provided with a follower. The other end of the central column is provided with a lifting control column. The other end of the lifting control column is threadedly connected to a bracket. The interior of the bracket is provided with a connecting rod. The outer wall of the bracket is provided with a fixed block. The fixed block is fixedly connected to two side plates. When the follower rotates, it controls the central column to rotate. The rotation of the central column controls the rotation of the lifting control column. The bracket is threadedly connected to the lifting control column. Therefore, at this time, the bracket is controlled to move up or down. When the follower rotates forward, the bracket rises. If the follower rotates in reverse, the bracket descends. The bracket moves up and down through the connecting rod, thereby achieving the effect of controlling the fixed block to drive the two side plates to move up and down.

[0013] Preferably, the moving assembly includes a plurality of stabilizing members. The plurality of stabilizing members are arranged at the bottom of the housing. The outer walls of the plurality of stabilizing members are respectively movably connected to the other ends of the plurality of connecting rods. The stabilizing members are located at the bottom of the housing and are used to increase the stability of the device. When the connecting rod controls the side plate to move up or down, the stabilizing member controls the housing to stand stably. The stability of the speaker is increased through the stabilizing member.

[0014] Preferably, a hidden opening is formed in the outer wall of the stabilizing member. A moving wheel is arranged inside the hidden opening. A moving plate is fixedly connected between the outer walls of the moving wheels. Control groups are arranged on the outer walls of the two moving plates. A control plate is fixedly connected to the outer wall of the control group. The inner wall of the control plate is fixedly connected to the outer wall of the limiting column. Since the volume of the combined floor-standing speaker is relatively large, it is extremely difficult to move the speaker. It requires the help of multiple people to carry it, and it is basically impossible for a single person to operate. At this time, the control plate is controlled to rotate downward at one end by a certain angle. The control plate controls the entire control group to move downward. Finally, the moving plate is controlled to drive the moving wheel to extend out of the hidden opening and land on the ground. Through the moving wheel, the effect of facilitating the movement of the housing is achieved.

[0015] Preferably, a motor is arranged inside the housing. The output shaft of the motor is fixedly connected to a main rotating member. A pipe fitting is fixedly connected to the outer wall of the main rotating member. The inner wall of the pipe fitting is slidably connected to the outer wall of the central column. The pipe fitting is a sleeve. The outer layer of the pipe is fixedly connected to the main rotating member. The inner pipe is not controlled by the main rotating member. When the motor is started, its output shaft controls the main rotating member to rotate. The main rotation controls one end of the pipe fitting to rotate. Through the main rotating member, the effect that the motor controls one end of the pipe fitting to rotate accordingly is achieved.

[0016] Preferably, a double-control shaft is fixedly installed on the outer wall of the lifting button, and the outer walls at both ends of the double-control shaft are respectively fixedly connected with fixed blocks, and the outer wall of one of the fixed blocks is provided with a limited slot, and the other end of the double-control shaft is rotatably connected with an assisting piece, and the outer wall of the assisting piece is provided with a ratchet piece, and one end of the ratchet piece is movably connected with the limited slot, and the outer wall of the double-control shaft is provided with a mounting block, and the outer wall of the mounting block is fixedly connected to the inner wall of the shell, and the outer wall of the double-control shaft is provided with an elastic reset piece, one end of the elastic reset piece is fixedly connected to the outer wall of the lifting button, and one end of the elastic reset piece is fixedly connected to the mounting block, and a square groove is provided inside the mounting block, and the size of the square groove just matches the size of the fixed block, and the lifting button is pressed inward, and the lifting button drives the assisting piece through the double-control shaft When the lever is in the locked position, the cam will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever, which in turn will release the lever.

[0017] Preferably, the teeth of the auxiliary member mesh with the teeth of the main rotating member, and the teeth of the auxiliary member mesh with the teeth of the slave rotating member. When the main rotating member rotates, the auxiliary member rotates accordingly, and the auxiliary member controls the rotation of the slave rotating member. If the auxiliary member is not in contact with the main rotating member, the main rotating member cannot control the slave rotating member.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The combined floor-standing speaker described in the present invention has the effect of preventing dust from entering the interior of the shell through the dustproof mechanism. The shape of the adjustment rod is a semicircular pancake-shaped object at one end, and the remaining part is a rack-shaped object on one side. Therefore, when the speaker is no longer in use, one end of the adjustment rod is controlled to rotate so as to control the dust cover to rotate to the front of the speaker along a fixed arc trajectory. Then, the rack of the adjustment rod is controlled to control the dust cover to slide straightly to the inside of the dustproof groove to cover the position of the speaker.

[0020] When the lifting and lowering button is pressed, the lifting and lowering button drives the auxiliary member to move inwardly through the double-control shaft. When one of the fixed card blocks passes through the square card slot inside the mounting block, the lifting and lowering button is rotated. The lifting and lowering button controls the two fixed card blocks to rotate at an angle. The fixed card blocks are controlled by the double-control shafts to be just close to the two sides of the mounting block and staggered with the direction card slot. Therefore, the double-control shafts are fixed in this position. The auxiliary member rotates due to meshing with the main rotating member. The elastic reset member generates a pulling force due to the deepening of the auxiliary gear. The ratchet member rotates with the auxiliary member and slides in contact with the limit card slot. When the auxiliary member is controlled to rotate in the opposite direction, the ratchet member rotates in the opposite direction with the auxiliary member. At this time, the ratchet member clamps the limit card slot and controls the rotation of the fixed card block located inside. When the fixed card block rotates to be completely consistent with the square slot, the elastic reset member contracts to pop the lifting and lowering button outward, and the auxiliary member stops rotating.

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0038] As Figure 1 and Figure 14 shown, a combined floor-standing speaker according to an embodiment of the present invention is characterized in that: it includes a housing 1, a dust-proof mechanism 100 is arranged outside the housing 1, a lifting mechanism 200 is arranged inside the housing 1, and a moving component 300 is arranged at the bottom of the housing 1;

[0039] A plurality of speakers 11 are arranged on the outer wall of the housing 1, a lifting button 12 and a moving switch 13 are arranged on the outer wall of the housing 1, a heat dissipation port 14 is opened on the outer wall of the housing 1, a limiting column 15 is fixedly connected to the inner wall of the moving switch 13, and side plates 16 are slidably connected to both sides of the outer wall of the housing 1;

[0040] When working, the shell 1 is the outer shell of the combined floor-standing speaker. The dustproof mechanism 100 is used to prevent dust in the air from entering the shell 1 through the speaker 11. The lifting mechanism 200 is used to control the lifting of the side panels 16 on both sides of the shell 1, so as to facilitate cleaning the interior of the speaker and prevent dust accumulation. The moving component 300 is used to control the movement of the speaker. When the speaker is used, the sound source is transmitted from the speaker 11, and the air flow rate inside the shell 1 is accelerated through the heat dissipation port 14, so as to achieve the effect of cooling the inside of the shell 1. Pressing the lifting button 12 can control the shell 1 to rise away from the ground, which is convenient for cleaning the bottom. Toggling the moving switch 13 can control the movement of the trolley. Through the control of the moving component 300 and the lifting mechanism 200, the movement of the shell 1 is controlled, and manual handling and movement are no longer required, making it easier to operate and use the floor-standing speaker.

[0041] like Figures 2 to 4 As shown, the dustproof mechanism 100 includes a dustproof cover 101, a dustproof groove 102 is formed on the outer wall of the housing 1, the outer wall of the dustproof cover 101 is interlaced with the inner wall of the dustproof groove 102, a fixing column 103 is fixedly installed on the inner wall of the dustproof cover 101, and an adjusting rod 104 is rotatably connected to the outer wall of the fixing column 103;

[0042] When working, the dustproof mechanism 100 is used to block external dust from entering the shell 1, and prevent dust from entering the shell 1 to increase the burden on the operation of the device, because the shape of the adjustment rod 104 is a semicircular pancake-shaped object at one end, and the remaining part is a rack-shaped object on one side; when the speaker is in use, the dust cover 101 is in front of the speaker 11, thereby reducing the impact on the sound effect of the speaker 11. When the speaker is no longer in use, one end of the adjustment rod 104 will rotate to control the dust cover 101 to rotate to the front of the speaker 11 along a fixed arc trajectory, and then the rack of the adjustment rod 104 is controlled to control the dust cover 101 to slide straightly to the inside of the dustproof groove 102 to cover the position of the speaker 11. The adjustment rod 104 is used to control the dust cover 101 to cover the speaker 11 and prevent dust from entering the shell 1.

[0043] like Figures 2 to 5 As shown, the adjustment rod 104 is slidably connected with the adjustment slide rail 105, an adjustment gear 106 is arranged inside the dustproof groove 102, the teeth of the adjustment gear 106 are meshed with the teeth of the adjustment rod 104, and a connecting piece 107 is arranged between the outer walls of the dustproof cover 101;

[0044] During operation, the control adjustment gear 106 rotates. The adjustment gear 106 meshes with the semi-circular gear of the adjustment rod 104, controlling one end of the adjustment rod 104 to deflect along a predetermined trajectory to the front of the speaker 11. Subsequently, due to the teeth of the adjustment rod 104 meshing with the teeth inside the adjustment slide rail 105, the adjustment rod 104 slides linearly inward along the adjustment slide rail 105 and retracts into the interior of the adjustment slide rail 105. When one of the dust covers 101 is controlled to move along a fixed arc and retract into the dust slot 102, the other dust covers 101 are all controlled to retract into the interior of the dust slot 102 due to the connecting member 107. If the speaker needs to be used, only the opposite operation to the above is required. Through the cooperation of the adjustment slide rail 105 and the adjustment rod 104, the effect of controlling the opening and closing of the dust cover 101 is achieved.

[0045] As Figure 5 shown, a screw rod 108 is fixedly connected to the outer wall of the adjustment gear 106, and a control member 109 is threadedly connected to the other end of the screw rod 108;

[0046] During operation, when the dust cover 101 needs to be opened, only the control member 109 needs to be pressed. The control member 109 moves downward and drives the screw rod 108 to rotate through threaded transmission. The screw rod 108 drives the adjustment gear 106 to rotate. When the dust cover 101 needs to be closed, only the control member 109 needs to be pulled upward. At this time, the adjustment gear 106 will rotate in the reverse direction. Through the control member 109, the effect of controlling the closing or opening of the dust cover 101 is achieved.

[0047] As Figure 6 shown, the lifting mechanism 200 includes a central column 201. A follower 202 is provided at one end of the central column 201, and a lifting control column 203 is provided at the other end of the central column 201. A bracket 204 is threadedly connected to the other end of the lifting control column 203. A connecting rod 205 is provided inside the bracket 204. A fixing block 302 is provided on the outer wall of the bracket 204, and the fixing block 302 is fixedly connected to the two side plates 16;

[0048] During operation, when the follower 202 rotates, it controls the central column 201 to rotate. The rotation of the central column 201 controls the rotation of the lifting control column 203. Since the bracket 204 is threadedly connected to the lifting control column 203, the bracket 204 is controlled to move up or down at this time. If the follower 202 rotates forward, the bracket 204 rises. If the follower 202 rotates in reverse, the bracket 204 descends. The bracket 204 rises and falls through the connecting rod 205, thus achieving the effect of controlling the fixing block 302 to drive the two side plates 16 to rise and fall, facilitating the cleaning of the interior of the speaker and preventing dust accumulation.

[0049] As Figure 6 and Figure 11As shown, the moving component 300 includes a plurality of stabilizers 301. The plurality of stabilizers 301 are arranged at the bottom of the housing 1, and the outer walls of the plurality of stabilizers 301 are respectively movably connected to the other ends of the plurality of connecting rods 205;

[0050] During operation, the stabilizers 301 are located at the bottom of the housing 1 and are used to increase the stability of the device. When the bracket 204 controls the two side plates 16 to rise or fall, the stabilizers 301 control the housing 1 to stand stably, and the effect of increasing the stability of the speaker is achieved through the stabilizers 301.

[0051] As Figures 12 to 13 shown, a hidden opening 303 is formed in the outer wall of the stabilizer 301. A moving wheel 304 is arranged inside the hidden opening 303. A moving plate 305 is fixedly connected between the outer walls of the moving wheels 304. Regulation groups 306 are arranged on the outer walls of the two moving plates 305. A regulation plate 307 is fixedly connected to the outer wall of the regulation group 306. The inner wall of the regulation plate 307 is fixedly connected to the outer wall of the limiting column 15;

[0052] During operation, since the volume of the combined floor-standing speaker is relatively large, it is extremely difficult to move the speaker. Multiple people need to help carry it, and it is basically impossible for a single person to operate. At this time, the controlled end of the regulation plate 307 rotates downward and deflects by an angle. The regulation plate 307 controls the overall downward movement of the regulation group 306. Finally, the moving plate 305 is controlled to drive the moving wheel 304 to extend out of the hidden opening 303 and land on the ground. Through the moving wheel 304, the effect of facilitating the control of the movement of the housing 1 is achieved.

[0053] As Figure 7 shown, a motor 308 is arranged inside the housing 1. The output shaft of the motor 308 is fixedly connected to a main rotating part 309. A pipe part 310 is fixedly connected to the outer wall of the main rotating part 309. The inner wall of the pipe part 310 is slidably connected to the outer wall of the central column 201;

[0054] During operation, when the motor 308 is started, its output shaft controls the main rotating part 309 to rotate, and the main rotating part 309 controls the pipe part 310 to rotate, achieving the effect that the motor 308 controls the pipe part 310 to rotate accordingly.

[0055] As Figures 6 to 10As shown, a double control shaft 311 is fixedly installed on the outer wall of the lifting button 12, and two fixed clamping blocks 315 are fixedly connected to the outer wall of the double control shaft 311, and a limit clamping groove 316 is arranged on the outer wall of one of the fixed clamping blocks 315, and an assisting member 312 is rotatably connected to the other end of the double control shaft 311, and a ratchet member 317 is arranged on the outer wall of the assisting member 312, and one end of the ratchet member 317 is movably connected to the limit clamping groove 316, and a mounting block 313 is arranged on the outer wall of the double control shaft 311, and the spacing between the two fixed clamping blocks 315 matches the width of the mounting block 313, and the outer wall of the mounting block 313 is fixedly connected to the inner wall of the shell 1, and an elastic reset member 314 is arranged on the outer wall of the double control shaft 311, and one end of the elastic reset member 314 is fixedly connected to the outer wall of the lifting button 12, and one end of the elastic reset member 314 is fixedly connected to the mounting block 313;

[0056] When working, a square slot is provided inside the mounting block 313, and the size of the square slot just matches that of the fixed card block 315. The lifting button 12 is pressed inward, and the lifting button 12 drives the auxiliary member 312 to move inward through the double control shaft 311. When one of the fixed card blocks 315 passes through the square slot inside the mounting block 313, the lifting button 12 is rotated, and the lifting button 12 controls the two fixed card blocks 315 to rotate by an angle. The fixed card blocks 315 are just close to the two sides of the mounting block 313 and staggered with the square slot. Therefore, the double control shaft 311 is fixed in this position, and the auxiliary member 312 rotates due to the engagement with the main rotating member 309, and the elastic reset member 314 Due to the penetration of the auxiliary member 312, a pulling force is generated. When the auxiliary member 312 is controlled to rotate forward, the ratchet member 317 rotates with the auxiliary member 312 and slides into contact with the limiting slot 316. When the auxiliary member 312 is controlled to rotate reversely, the ratchet member 317 rotates reversely with the auxiliary member 312. At this time, the ratchet member 317 clamps the limiting slot 316 and controls the rotation of the fixed block 315 located inside. When the fixed block 315 rotates to completely match the square groove, the elastic reset member 314 contracts to pop the lifting button 12 outward. At this time, the auxiliary member 312 stops rotating. Through the cooperation of the above-mentioned structure, the effect of controlling the rotation and stopping of the auxiliary member 312 is achieved.

[0057] like Figure 8 As shown, the teeth of the assisting member 312 mesh with the teeth of the main rotating member 309, and the teeth of the assisting member 312 mesh with the teeth of the slave rotating member 202;

[0058] During operation, when the main rotating member 309 rotates, the auxiliary member 312 rotates accordingly, and the auxiliary member 312 controls the rotation of the slave rotating member 202 . If the auxiliary member 312 is not in contact with the main rotating member 309 , the main rotating member 309 cannot control the slave rotating member 202 .

[0059] Working principle: Shell 1 is the shell of combined floor-standing speakers. Dust-proof mechanism 100 is used to prevent dust in the air from entering the interior of shell 1 through speaker 11. Press control member 109, and control member 109 moves downward to drive screw 108 to rotate through thread transmission. Screw 108 drives adjusting gear 106 to rotate. When you want to close dust cover 101, just pull control member 109 upward, and adjusting gear 106 will rotate in the opposite direction. Through control member 109, the effect of controlling the closing or opening of dust cover 101 is achieved. The shape of adjusting rod 104 is a pancake-shaped object with a semicircular end, and the remaining part is a rack-shaped object on one side. Therefore, when the speaker is no longer in use, control adjusting gear 106 to rotate, and adjusting gear 106 and adjusting rod 1 04 is meshed with the semicircular gear, and one end of the control adjustment rod 104 is deflected to the front of the speaker 11 along a predetermined trajectory. Then, the teeth of the adjustment rod 104 are meshed with the teeth inside the adjustment slide rail 105, so that the adjustment rod 104 slides inwardly along the adjustment slide rail 105 and retracts back into the adjustment slide rail 105. When one of the dust covers 101 is controlled to move along a fixed arc and retract into the dust groove 102, the other dust covers 101 are controlled to retract into the dust groove 102 due to the connecting piece 107. If the speaker needs to be used, only the opposite operation to the above can be performed. By adjusting the cooperation between the slide rail 105 and the adjustment rod 104, the dust cover 101 is controlled to be opened and closed, preventing dust from leaking. The lifting mechanism 200 is used to control the lifting of the side panels 16 on both sides of the shell 1, so as to facilitate the cleaning of the interior of the speaker and prevent the accumulation of dust. When the motor 308 is started, its output shaft controls the main rotating member 309 to rotate, and the main rotating member 309 controls the pipe 310 to rotate. When the slave rotating member 202 rotates, the central column 201 is controlled to rotate. A square groove is provided inside the mounting block 313, and the size of the square groove just matches the size of the fixed card block 315. Press the lifting button 12 inward, and the lifting button 12 drives the auxiliary member 312 to move inward through the double control shaft 311. When one of the fixed card blocks 315 passes through the square card slot inside the mounting block 313, the lifting button 12 is rotated, and the lifting button 12 The two fixed blocks 315 are controlled to rotate at an angle, and the fixed blocks 315 are just close to the two sides of the mounting block 313 and staggered with the square slots, so that the double control shaft 311 is fixed at this position, and the auxiliary member 312 rotates due to the meshing with the main rotating member 309, and the elastic reset member 314 generates a pulling force due to the deepening of the auxiliary member 312, and the ratchet member 317 rotates with the auxiliary member 312 and slides into contact with the limiting slot 316. When the auxiliary member 312 is controlled to rotate in the opposite direction, the ratchet member 317 rotates in the opposite direction with the auxiliary member 312. At this time, the ratchet member 317 clamps the limiting slot 316 and controls the rotation of the fixed block 315 located inside. When the fixed block 315 rotates to completely match the square slot, the elastic reset member 314 contracts to pop the lifting button 12 outward.At this time, the assisting member 312 stops rotating, and the central column 201 rotates to control the rotation of the lifting control column 203. The bracket 204 is threadedly connected to the lifting control column 203, so the bracket 204 is controlled to move up or down. If the rotating member 202 rotates forward, the bracket 204 rises, and if the rotating member 202 rotates reversely, the bracket 204 falls. The moving component 300 is used to control the movement of the speaker. When the speaker is used, the sound source is transmitted from the speaker 11, and the air flow rate inside the shell 1 is accelerated through the heat dissipation port 14, so as to achieve the effect of cooling the inside of the shell 1. Pressing the lifting button 12 can control the shell 1 to rise away from the ground, which is convenient for cleaning the bottom. Toggle the moving switch 1 3 can control the trolley to move. Through the control of the moving assembly 300 and the lifting mechanism 200, the housing 1 can be controlled to move. Since the combined floor-standing speakers are relatively large, it is extremely difficult to move the speakers. It requires multiple people to help carry them. One person can basically not operate them. At this time, the control board 307 is controlled to rotate downward at one end to deflect an angle. The control board 307 controls the control group 306 to move downward as a whole. Finally, the moving board 305 is controlled to drive the moving wheel 304 to extend out of the hidden opening 303 and fall to the ground. Through the moving wheel 304, the housing 1 is easily controlled to move. Manual handling and movement are no longer required, and the floor-standing speakers are easier to operate and use.
