When the speakers enter the fixed machine box, the fixed machine assembly in the fixed machine box is used to fix the speakers. At this time, the installation of the speakers is completed. When the speakers need to be replaced or removed, the removing assembly is turned, and the removing assembly drives the fixed machine assembly to loosen, and then the speakers can be taken out of the fixed machine box, which is convenient for taking out the speakers. By placing the supporting assembly between two walls, the problem of needing to make holes in the wall for fixing with bolts, which affects the appearance, can be solved. The more troublesome problems during installation can be solved by the fixed machine assembly and the removing assembly.

[0008] Preferably, the supporting assembly includes a vertical rod, a rectangular frame is fixedly installed on the top of the vertical rod, and four groups of sliding grooves are symmetrically opened on the inner wall of the rectangular frame, the inner walls of the four groups of sliding grooves are slidably connected with shaft rods, the outer walls of the four shaft rods are hinged with support rods, and the bottom ends of the four support rods are fixedly installed with foot blocks, and the bottoms of the four foot blocks are slidably connected to the bottom of the inner wall of the support box. When the supporting assembly is released, the support rod will slide in the rectangular frame at the top of the vertical rod through the shaft rod. While sliding, the two ends of the shaft rod slide in the sliding grooves on the rectangular frame, and the foot blocks on the bottom ends of the support rods will slide inside the support box, thereby allowing the support rod to extend from the inside of the support box.

[0009] Preferably, a rope connection is provided inside the vertical rod, and the four ends of the rope connection pass through the inner wall of the vertical rod and are respectively fixedly connected to the inner sides of the four support rods, and return springs are provided between the outer wall of the vertical rod and the four support rods, and the four return springs are respectively placed on the outside of the four ends of the rope connection. When the supporting assembly is tightened, the support rod is pulled by the rope connection to squeeze the return spring to shrink and move into the support frame box, and the support rod will be placed inside the support frame box. During installation, the support frame box is placed between the two walls, and the rope connection is then released. The support rod will extend out of the support frame box under the action of the elastic force of the return spring and return to its original position. When the four support rods are fully extended, the four support rods will present a support shape and be firmly hung between the two walls. By hanging the four support rods between the two walls, the step of drilling holes in the wall when installing the audio system to facilitate fixing the hanging plate can be saved, and at the same time, the visual difference caused by drilling holes can be avoided, which affects the beauty of the interior decoration.

[0016] Preferably, the inner wall of the speaker is provided with a hanging groove. When the speaker is installed, when the top of the speaker contacts the limit ring, the speaker will be unable to move. At this time, the four hook arms will lose the thrust of the speaker, and the hook arms will slide out from between the two moment plates due to the elastic force of the pressure spring. The four hook arms will be firmly stuck in the hanging groove on the inner wall of the speaker, thereby fixing the speaker.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The embedded ceiling speaker described in the present invention uses a rope connection to pull the support rod to squeeze the reset spring to retract and move into the support box, so that the support rod will be placed inside the support box. The support box is placed between two walls, and then the rope connection is loosened. The support rod will extend from the support box and reset under the action of the elastic force of the reset spring. When the four support rods are fully extended, the four support rods will appear as a support frame and be firmly hung between the two walls. By hanging the four support rods between the two walls, the step of drilling holes in the wall and fixing the hanger with bolts when installing the speakers can be saved. At the same time, the visual difference caused by drilling holes can be avoided, which affects the beauty of the interior decoration.

[0019] 2. The embedded ceiling speaker described in the present invention can rotate the unloading plate, and the pull rope in the unloading plate will pull the frame rod to slide on the inner wall of the fixed machine box. When the frame rod slides in the fixed machine box, one end of the frame rod drives the hanging arm rod to squeeze the pressure spring to slide on the positioning slide shaft, and the bottom end of the hanging arm rod will extend out of the speaker.

[0037] When the supporting assembly is released, the support rod 8 will slide in the rectangular frame 9 at the top of the vertical rod 7 through the shaft rod 13. While sliding, the two ends of the shaft rod 13 will slide in the slide grooves 12 on the rectangular frame 9, and the foot block 10 on the bottom end of the support rod 8 will slide inside the frame box 1, so that the support rod 8 extends out from the inside of the frame box 1. It should be noted here that the initial position of the support rod 8 is placed outside the frame box 1.

[0038] like Figure 3 to Figure 4 As shown, a rope connecting member 16 is arranged inside the vertical rod 7, and the four ends of the rope connecting member 16 penetrate the inner wall of the vertical rod 7 and are respectively fixedly connected to the inner sides of the four struts 8, and a return spring 14 is arranged between the outer wall of the vertical rod 7 and the four struts 8, and the four return springs 14 are respectively placed outside the four ends of the rope connecting member 16;

[0039] When the supporting assembly is tightened, the support rod 8 is pulled by the rope connection 16 to squeeze the reset spring 14 and retract and move into the support box 1, and the support rod 8 will be placed inside the support box 1. During installation, the support box 1 is placed between the two walls, and then the rope connection 16 is loosened, and the support rod 8 will extend out of the support box 1 under the action of the elastic force of the reset spring 14 and reset. When the four support rods 8 are fully extended, the four support rods 8 will be firmly hung between the two walls in a support shape. By hanging the four support rods 8 between the two walls, the step of drilling holes in the wall when installing the speakers 28 can be saved to facilitate fixing the hanging plate. At the same time, the visual difference caused by drilling holes can be avoided, which affects the beauty of the interior decoration.

[0041] During operation, by pulling the pull plate 17, the pull plate 17 drives the rope connection 16 to retract through the pull rod 15, and the four struts 8 will squeeze the reset spring 14 to retract and move into the support box 1. When the pull plate 17 is released, the rope connection 16 loses the tension, and the four struts 8 will be reset under the action of the elastic force of the reset spring 14, which plays a role in controlling the extension and retraction of the struts 8. The setting of the plate block 30 is to facilitate pulling the pull plate 17.

[0042] like Figure 3 to Figure 4 As shown, the inner wall of the support box 1 is provided with four through slots 6, and four sets of limit plates 11 are fixedly installed at the inner bottom end of the support box 1. The outer walls of the four support rods 8 and the foot blocks 10 are respectively slidably connected to the inner walls of the four through slots 6, and the tops of the four foot blocks 10 are respectively slidably connected to the bottoms of the four sets of limit plates 11;

[0043] When the support rod 8 extends and retracts in the support box 1, the support rod 8 extends and retracts in the support box 1 through the through groove 6. The setting of the limit plate 11 is to provide a limit for the movement of the support rod 8 when the support rod 8 drives the foot block 10 to extend and retract, thereby preventing the support rod 8 from moving when extending, and playing the role of limiting movement.

[0044] like Figures 5 and 6 As shown, a limit ring 3 is fixedly installed on the top of the inner wall of the fixed machine box 2, and a threading hole 18 is opened on the inner wall of the limit ring 3;

[0045] When installing the speaker 28, place the speaker 28 in the fixing box 2. When the top of the speaker 28 contacts the limit ring 3, stop moving the speaker 28. Then the fixing assembly in the fixing box 2 will fix the speaker 28. The threading hole 18 is provided to facilitate the connection of the wires to the speaker 28.

[0046] like Figures 6 to 8 As shown, the fixed machine assembly includes a hook arm 21, a sliding opening 27 is opened on the inner wall of the limit ring 3, the top of the hook arm 21 is slidably connected to the inner wall of the sliding opening 27, the inner wall of the fixed machine box 2 is symmetrically fixed with a rectangular plate 20, the hook arm 21 is placed between the two rectangular plates 20 and is slidably connected to the inner walls of the two rectangular plates 20, a position correction sliding shaft 23 is fixedly installed on the inner wall of the fixed machine box 2, the outer wall of the position correction sliding shaft 23 is slidably connected to the inner wall of the hook arm 21, a pressure spring 22 is fixedly installed between the hook arm 21 and the inner wall of the fixed machine box 2, and the pressure spring 22 is placed outside the position correction sliding shaft 23;

[0047] When the speaker 28 is placed in the fixing box 2, the speaker 28 is moved upward. When the speaker 28 moves upward, the outer wall of the speaker 28 will squeeze the hook arm 21 and move backward between the two rectangular plates 20. When the hook arm 21 moves backward, the hook arm 21 squeezes the pressure spring 22 to slide on the correction slide shaft 23. When the top of the speaker 28 contacts the limit ring 3, the speaker 28 will be unable to move. The hook arm 21 will slide out from between the two rectangular plates 20 due to the elastic force of the pressure spring 22. The four hook arms 21 will be firmly stuck on the inner wall of the speaker 28, thereby completing the fixation of the speaker 28 and playing the role of fixing the speaker 28.

[0048] like Figure 6 to Figure 7 As shown, the machine removal assembly includes a machine unloading plate 5, which is fixedly installed at the bottom end of the fixed machine box 2, a frame rod 19 is fixedly installed on the outer wall of the hanging arm rod 21, and the inner walls of the two rectangular plates 20 are both provided with a slide rod opening 24, and the top of the frame rod 19 is slidably connected to the inner wall of the slide rod opening 24, and a pull rope 26 is fixedly installed on the inner wall of the unloading plate 5, one end of the pull rope 26 is fixedly connected to the bottom end of the frame rod 19, and the bottom end of the frame rod 19 is slidably connected to the inner wall of the fixed machine box 2;

[0049] When it is necessary to remove the speaker 28 from the fixed machine box 2, by rotating the unloading plate 5, the pull rope 26 in the unloading plate 5 will pull the frame rod 19 to slide on the inner wall of the fixed machine box 2. While the frame rod 19 slides in the fixed machine box 2, one end of the frame rod 19 drives the hanging arm rod 21 to squeeze the pressure spring 22 to slide on the correction slide shaft 23, and the bottom end of the hanging arm rod 21 will extend out of the speaker 28. The speaker 28 will lose the limiting fixing force from the hanging arm rod 21, and then the speaker 28 can be taken out of the fixed machine box 2. The opening of the slide rod mouth 24 provides a way for the frame rod 19 to slide, which facilitates disassembly.

[0050] like Figure 6 to Figure 7 As shown, a ring plate 4 is fixedly installed on the outer wall of the bottom end of the fixed machine box 2, and the position of the ring plate 4 is placed just above the unloading plate 5. A pull-down shaft 25 is fixedly installed on the bottom of the ring plate 4.

The outer wall of the pull-down shaft 25 is slidably connected to the inner wall of the unloading plate 5, and the outer wall of the pull rope 26 is slidably connected to the outer wall of the pull-down shaft 25.

[0051] While the unloading disc 5 is rotating, the pull shaft 25 on the ring disc 4 opposite to the unloading disc 5 passes through the inner wall of the unloading disc 5 and is placed inside the unloading disc 5. When the unloading disc 5 rotates and the frame rod 19 is pulled by the pull rope 26, the pull rope 26 slides on the outer wall of the pull shaft 25. The setting of the pull shaft 25 makes it easier for the pull rope 26 to pull the frame rod 19. At the same time, the setting of the pull shaft 25 can provide a certain stability for the pull rope 26 to pull the frame rod 19.

[0052] like Figures 8 to 9 As shown, the inner wall of the speaker 28 is provided with a hanging groove 29;

[0053] When installing the speaker 28, when the top of the speaker 28 contacts the limit ring 3, the speaker 28 will be unable to move. At this time, the four hook arms 21 will lose the thrust of the speaker 28, and the hook arms 21 will slide out from between the two rectangular plates 20 due to the elastic force of the pressure spring 22. The four hook arms 21 will be firmly stuck in the hanging groove 29 on the inner wall of the speaker 28, thus completing the fixation of the speaker 28. It should be noted here that the opening position of the hanging groove 29 and the position of the hook arm 21 need to be actually measured and calculated.

[0054] Working principle: by pulling the supporting assembly in the supporting frame box 1, and then placing the supporting frame box 1 between the two walls, and then releasing the supporting assembly in the supporting frame box 1, the supporting assembly in the supporting frame box 1 will be opened from the supporting frame box 1 and placed between the two walls, and then the speaker 28 is placed in the fixed machine box 2 at the bottom of the supporting frame box 1. When the speaker 28 enters the fixed machine box 2, the fixed machine assembly in the fixed machine box 2 is used to fix the speaker 28. At this time, the installation of the speaker 28 is completed. When the speaker 28 needs to be replaced or removed, the machine removal assembly is rotated, and the machine removal assembly drives the fixed machine assembly to loosen, and then the speaker 28 is taken out of the fixed machine box 2, which is convenient for taking out the speaker 28. By placing the supporting assembly between the two walls, the problem of needing to make a hole in the wall for fixing with bolts, which affects the appearance, can be solved. The problem of being more troublesome during installation can be solved by the fixed machine assembly and the removing assembly.

[0055] When the support assembly is released, the support rod 8 will slide in the rectangular frame 9 at the top of the vertical rod 7 through the shaft rod 13. While sliding, the two ends of the shaft rod 13 slide in the slide grooves 12 on the rectangular frame 9, and the foot block 10 on the bottom end of the support rod 8 will slide inside the support frame box 1, so that the support rod 8 extends out from the inside of the support frame box 1;

[0056] When the support assembly is tightened, the rope connecting piece 16 pulls the support rod 8 to squeeze the reset spring 14 and retract it into the support box 1, and the support rod 8 will be placed inside the support box 1. During installation, the support box 1 is placed between the two walls, and then the rope connecting piece 16 is loosened, and the support rod 8 will extend out of the support box 1 under the elastic force of the reset spring 14 and reset. When the four support rods 8 are fully extended, the four support rods 8 will be firmly hung between the two walls in a support shape. By hanging the four support rods 8 between the two walls, it can save the step of drilling holes on the wall when installing the sound system 28 to facilitate fixing the hanging plate, and it can also avoid the visual difference caused by drilling holes, which affects the beauty of interior decoration.

[0057] When working, by pulling the pull plate 17, the pull plate 17 drives the rope connecting member 16 to retract through the pull rod 15, and the four struts 8 will squeeze the reset spring 14 to retract and move into the support frame box 1. When the pull plate 17 is released, the rope connecting member 16 loses the tension, and the four struts 8 will be reset under the elastic force of the reset spring 14, which plays a role in controlling the extension and retraction of the struts 8. The setting of the plate block 30 is to facilitate pulling the pull plate 17;

[0058] When the support rod 8 extends and retracts in the support box 1, the support rod 8 extends and retracts in the support box 1 through the through slot 6. The setting of the limit plate 11 is to provide a limit for the movement of the support rod 8 when the support rod 8 drives the foot block 10 to extend and retract, so as to prevent the support rod 8 from moving when extending, and play the role of limiting movement;

[0059] When installing the speaker 28, place the speaker 28 in the fixing box 2. When the top of the speaker 28 contacts the limit ring 3, stop moving the speaker 28. Then the fixing assembly in the fixing box 2 will fix the speaker 28. The threading hole 18 is provided to facilitate the connection of the wires to the speaker 28.

[0060] When the speaker 28 is placed in the fixing box 2, the speaker 28 is moved upward. When the speaker 28 moves upward, the outer wall of the speaker 28 will squeeze the hook arm 21 to move backward between the two rectangular plates 20. When the hook arm 21 moves backward, the hook arm 21 squeezes the pressure spring 22 to slide on the correction slide shaft 23. When the top of the speaker 28 contacts the limit ring 3, the speaker 28 cannot move. The hook arm 21 will slide out from between the two rectangular plates 20 due to the elastic force of the pressure spring 22. The four hook arms 21 will be firmly stuck to the inner wall of the speaker 28, completing the fixation of the speaker 28 and playing the role of fixing the speaker 28.

[0061] When it is necessary to remove the speaker 28 from the fixed machine box 2, by rotating the unloading plate 5, the pull rope 26 in the unloading plate 5 will pull the frame rod 19 to slide on the inner wall of the fixed machine box 2. While the frame rod 19 slides in the fixed machine box 2, one end of the frame rod 19 drives the hanging arm rod 21 to squeeze the pressure spring 22 to slide on the correction slide shaft 23, and the bottom end of the hanging arm rod 21 will extend out of the speaker 28, and the speaker 28 will lose the limiting retention force of the hanging arm rod 21. Then, the speaker 28 can be taken out of the fixed machine box 2. The opening of the slide rod opening 24 provides a way for the sliding of the frame rod 19, which plays a role in facilitating disassembly.

[0062] While the unloading plate 5 is rotating, the pull shaft 25 on the ring plate 4 opposite to the unloading plate 5 penetrates the inner wall of the unloading plate 5 and is placed inside the unloading plate 5. When the unloading plate 5 rotates and the rack rod 19 is pulled by the pull rope 26, the pull rope 26 slides on the outer wall of the pull shaft 25. The setting of the pull shaft 25 can facilitate the pull rope 26 to pull the rack rod 19. At the same time, the setting of the pull shaft 25 can provide a certain stability for the pull rope 26 to pull the rack rod 19.

[0063] When installing the speaker 28, when the top of the speaker 28 contacts the limit ring 3, the speaker 28 will be unable to move. At this time, the four hook arms 21 will lose the thrust of the speaker 28, and the hook arms 21 will slide out from between the two rectangular plates 20 due to the elastic force of the pressure spring 22. The four hook arms 21 will be firmly stuck in the hanging groove 29 on the inner wall of the speaker 28, thereby fixing the speaker 28.
