Description

Technical Field

[0001] This invention relates to the field of ceiling speaker technology, specifically a recessed ceiling speaker. Background Technology

[0002] A ceiling speaker is an audio playback device installed inside the ceiling. It has advantages such as spatial adaptability, improved listening experience, practical functionality, and high scene compatibility, and is widely used in various locations. However, during the use of ceiling speakers, dust is always floating in the air, such as particles brought in from outdoors, indoor fabric fibers, and human skin flakes. Ceiling speakers passively receive this settled dust, and the accumulation of this dust can affect the normal operation of the ceiling speaker. To overcome this defect, prior art 1 (Chinese patent application No. 202220562704.8, application date 2022-03-11) describes a ceiling speaker using an aluminum alloy panel. During use, the speaker body can be quickly disassembled and assembled, facilitating maintenance and repair, and making it easy to clean the dust from the grille. Prior art 2 (application No. 202221409652) also describes this feature. 7. A Chinese patent application filed on 2022-06-07) describes a two-way low-impedance ceiling speaker that is convenient for use in meetings. During use, it can be easily covered by a shielding mechanism during maintenance, so that dust falling into the shielding cloth is difficult to disperse into the air, thus preventing dust from falling into the eyes of maintenance personnel and causing eye injury. Prior art 3 (Chinese patent application number 202121159598.0, filed on 2021-05-27) describes a surface-mountable ceiling speaker. During use, the dual-axis motor is connected to the power supply, and the dual-axis motor drives two rotating rods to rotate. The rotating rods drive the first gear to rotate. When the two first gears rotate, they drive the two protective covers to flip open through the meshing second gear. When not in use, the protective covers can be flipped and closed to protect the speaker from dust entering and prevent the speaker from being damaged by objects thrown from below.

[0003] When the ceiling speaker is working, stubborn dust and impurities can form on its lower surface due to humidity or cigarette tar. During cleaning, a single cleaning method is insufficient to remove the stubborn dust. The device in the aforementioned application does not have multiple cleaning structures, so impurities will still remain on the lower surface of the ceiling speaker, affecting its subsequent use. Summary of the Invention

[0004] The purpose of this invention is to provide a recessed ceiling speaker that solves the problem mentioned in the background art, where impurities remain on the lower surface of the ceiling speaker during use due to the lack of multiple cleaning structures, which affects the subsequent use of the ceiling speaker.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a recessed ceiling speaker, comprising an auxiliary plate and an outer frame, wherein the auxiliary plate and the outer frame are connected by a snap-fit ​​assembly, and the speaker body is disposed inside the outer frame, and the auxiliary plate is connected to the indoor ceiling; elongated holes are provided on both the left and right sides of the outer frame, and a working tube is connected inside the outer frame by a reversing assembly; a slider is slidably disposed inside the outer frame, and a working airbag is bonded to the right side surface of the slider, and a compression plate corresponding to the working airbag is connected to the right side of the slider by a reciprocating assembly.

The inner wall of the auxiliary plate is convex, and a positioning groove corresponding to the locking block is provided inside the auxiliary plate.

[0007] Preferably, a lever is fixedly connected to the lower surface of the card block, and a main airbag is bonded to the surface of the lever. The left side surface of the main airbag is in contact with the inner wall of the outer frame. An auxiliary airbag is connected to the main airbag through an external hose, and the surface of the auxiliary airbag is in contact with the inner wall of the outer frame.

[0008] Preferably, the outer frame has protrusions on both the upper and lower sides. The reversing assembly includes a motor fixedly connected to the surface of the upper protrusion, and the output end of the motor is fixedly connected to a threaded rod. A force-bearing block is threadedly connected to the surface of the threaded rod, and the surface of the force-bearing block is in contact with the inner wall of the elongated hole on the left side.

[0009] Preferably, the force-bearing block is provided with a connecting shaft that rotates inside, and the surface of the connecting shaft is provided with a groove, which is an inclined annular shape, and the force-bearing block is provided with a working tube that rotates inside.

[0010] Preferably, a traction rope is fixedly connected to the surface of the protruding position at the lower end of the outer frame, and the other side of the traction rope is wound and fixedly connected to the surface of the connecting shaft. An external rod is fixedly connected to the surface of the working tube, and the end of the external rod is located inside the groove. A torsion spring is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the force-bearing block.

[0011] Preferably, the reversing assembly further includes a lower connecting rod fixedly connected to the lower surface of the outer frame, and the surface of the working tube is provided with a guide groove, which is spiral in shape, and the end of the lower connecting rod is located inside the guide groove.

[0012] Preferably, the upper surface of the working tube is provided with nozzles, and the nozzles are evenly distributed on the surface of the working tube, and the surface of the working tube is provided with brush components.

[0013] Preferably, the reciprocating assembly includes a limiting rod fixedly connected to the surface of the slider, and the surface of the limiting rod is sleeved with the extrusion plate. The surface of the working tube is convex, and the surface of the working tube is sleeved with the extrusion plate. The lower surface of the working tube is provided with a connecting tube, and the slider is slidably disposed inside the elongated hole on the right side.

[0014] Preferably, the surface of the working airbag is in contact with the surface of the extrusion plate, and an upper pipe is fixedly connected to the upper surface of the working airbag, and a lower pipe is fixedly connected to the lower surface of the working airbag. The upper pipe is connected to the connecting pipe on the lower surface of the working pipe through an external hose, and a one-way valve is provided on the surface of both the upper pipe and the lower pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The novel structural design allows for quick assembly and disassembly of the outer frame and speaker body; it also features a multi-directional working tube for efficient cleaning of the lower surface of the outer frame, ensuring that the operation of the outer frame and speaker body is not affected by dust, resulting in high cleaning efficiency. The specific details are as follows: This recessed ceiling speaker requires the auxiliary plate to be aligned with the desired external position. During installation, the outer frame is aligned with the auxiliary plate, and then the outer frame is pushed into the auxiliary plate. The end of the locking block enters the positioning groove to complete the installation. When the lower surface of the outer frame needs to be cleaned, the motor works, and the working tube cleans the bottom of the outer frame from multiple angles, which is highly efficient and leaves no impurities.

[0016] Furthermore, during the outer frame docking process, the locking block drives the pushing block to move synchronously. After the locking block enters the positioning groove, the pushing block is in a state of squeezing the main airbag. At this time, the air inside the main airbag enters the auxiliary airbag, which in turn inflates the auxiliary airbag and holds the auxiliary plate, thus improving the stability of the outer frame after installation.

[0017] When the motor is working, the threaded rod and the elongated hole work together to move the slider, the force block, and the working tube in the horizontal direction. At this time, the working tube can clean the dust on the lower surface of the outer frame. At the same time, the working tube will also swing under the action of the lower connecting rod and the guide groove, and then the brush on the surface of the working tube will clean the dust on the lower surface of the outer frame from multiple angles, thus achieving a multi-directional cleaning effect.

[0018] This recessed ceiling speaker, during the horizontal movement of the working tube, drives the extrusion plate to move synchronously. The extrusion plate then intermittently extrudes the working airbag. At this time, the working airbag supplies air to the working tube through the upper pipe and the external hose, and the working tube intermittently blows air, which helps to blow away impurities and accelerate their falling, thus optimizing the cleaning effect.

[0019] Furthermore, during the lateral movement and swinging of the working tube, the protrusions on the surface of the working tube will drive the extrusion plate to move normally, while the limiting rod prevents the extrusion plate from swinging, which can apply reasonable pressure to the working airbag and ensure the working efficiency of the working airbag.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present invention provides the following technical solution: a recessed ceiling speaker.

[0024] Example 1: The locking block 3, main airbag 6, and auxiliary airbag 7 provide for rapid installation and auxiliary stability. Figures 1-6 As shown, it includes an auxiliary plate 1 and an outer frame 2. The auxiliary plate 1 and the outer frame 2 are connected by a snap-fit ​​assembly, and the speaker body is installed inside the outer frame 2. The auxiliary plate 1 is connected to the indoor ceiling. The left and right sides of the outer frame 2 are provided with elongated holes 24, and the working tube 11 is connected inside the outer frame 2 by a reversing assembly.

[0025] The locking assembly includes a locking block 3 slidably disposed inside the outer frame 2, with the upper surface of the locking block 3 being inclined, and a connecting spring 4 fixedly connected to the back of the locking block 3, and the other side of the connecting spring 4 being fixedly connected to the inner wall of the outer frame 2. The inner wall of the auxiliary plate 1 is convex, and a positioning groove corresponding to the locking block 3 is opened inside the auxiliary plate 1. A lever 5 is fixedly connected to the lower surface of the locking block 3, and a main airbag 6 is bonded to the surface of the lever 5. The left side surface of the main airbag 6 is in contact with the inner wall of the outer frame 2. The main airbag 6 is connected to an auxiliary airbag 7 through an external hose, and the surface of the auxiliary airbag 7 is in contact with the inner wall of the outer frame 2.

[0026] During the docking process of the outer frame 2, the outer frame 2 is inserted into the interior of the auxiliary plate 1. At this time, the inclined surface of the locking block 3 is pushed by the lower surface of the auxiliary plate 1, and the locking block 3 moves in the direction of pressing the connecting spring 4. After the upper surface of the outer frame 2 contacts the protruding position of the auxiliary plate 1, the locking block 3 and the positioning groove are in the same horizontal direction. At this time, the locking block 3 enters the interior of the positioning groove under the action of the connecting spring 4 (e.g., Figure 3 and Figure 4As shown), when the locking block 3 moves, it drives the lever 5 to compress the main airbag 6. At this time, the main airbag 6 delivers airflow to the interior of the auxiliary airbag 7 through the hose, causing the auxiliary airbag 7 to inflate (as shown). Figure 6 As shown in the figure, the airbag 7 then presses against the auxiliary plate 1, increasing friction and making the docking of the outer frame 2 more stable.

[0027] When it is necessary to disassemble the outer frame 2, pull the lever 5 so that the lever 5 moves the end of the locking block 3 out of the slot. At this time, the outer frame 2 and the auxiliary plate 1 are not in a locked state, and the outer frame 2 can be removed.

[0028] Example 2: Unlike Example 1, the horizontally movable working tube 11 can efficiently clean dust and impurities from the lower surface of the outer frame 2. Figures 7-12 As shown, a slider 10 is slidably disposed inside the outer frame 2, and a working airbag 17 is bonded to the right side surface of the slider 10. Furthermore, a compression plate 15 corresponding to the working airbag 17 is connected to the right side of the slider 10 via a reciprocating assembly.

[0029] The outer frame 2 has protrusions on both the upper and lower sides. The reversing assembly includes a motor fixedly connected to the surface of the upper protrusion, and the output end of the motor is fixedly connected to a threaded rod 8. The surface of the threaded rod 8 is threadedly connected to a force-bearing block 9. The surface of the force-bearing block 9 is in contact with the inner wall of the left long hole 24. The inside of the force-bearing block 9 is rotatably provided with a connecting shaft 13, and the surface of the connecting shaft 13 is provided with a groove 14, which is an inclined annular shape. The inside of the force-bearing block 9 is rotatably provided with a working tube 11.

[0030] A traction rope 12 is fixedly connected to the surface of the protruding position at the lower end of the outer frame 2, and the other side of the traction rope 12 is wrapped and fixedly connected to the surface of the connecting shaft 13. An external rod 18 is fixedly connected to the surface of the working tube 11, and the end of the external rod 18 is located inside the groove 14. A torsion spring 19 is fixedly connected to the surface of the connecting shaft 13, and the other side of the torsion spring 19 is fixedly connected to the inner wall of the force block 9.

[0031] When the outer frame 2 is working, the motor can be started intermittently to rotate the threaded rod 8. This causes the force-bearing block 9 and the slider 10 to move horizontally under the action of the elongated hole 24 and the threaded rod 8. At this time, the connecting shaft 13 rotates inside the force-bearing block 9 under the action of the traction rope 12 (e.g., ...). Figure 10 and Figure 11 As shown), at this time, the connecting shaft 13 drives the working tube 11 to move laterally inside the force block 9 and the slider 10 through the groove 14 and the external rod 18. At this time, the brush on the surface of the working tube 11 can efficiently clean the impurities on the lower surface of the outer frame 2.

[0032] Example 3: Unlike Example 2, the lower connecting rod 20 and guide groove 21 allow the working tube 11 to be in a swinging state, such as... Figures 9-12 As shown, the reversing assembly also includes a lower connecting rod 20 fixedly connected to the lower surface of the outer frame 2. A guide groove 21 is provided on the surface of the working tube 11, and the guide groove 21 is spiral. The end of the lower connecting rod 20 is located inside the guide groove 21. A nozzle is provided on the upper surface of the working tube 11, and the nozzles are evenly distributed on the surface of the working tube 11. A brush is provided on the surface of the working tube 11.

[0033] During the lateral movement of the working tube 11, the guide groove 21 moves relative to the lower connecting rod 20. At this time, the guide groove 21 cooperates with the lower connecting rod 20, and the working tube 11 is in a reciprocating swing state, which increases the working range of the working tube 11 again and improves the cleaning effect.

[0034] Example 4: Unlike Example 3, the working airbag 17 allows the working tube 11 to also have a blowing function during operation, optimizing the cleaning effect. Figure 13 and Figure 14 As shown, the reciprocating assembly includes a limiting rod 16 fixedly connected to the surface of the slider 10, and a pressing plate 15 is sleeved and connected to the surface of the limiting rod 16. The surface of the working tube 11 is convex, and the pressing plate 15 is sleeved and connected to the surface of the working tube 11. A connecting tube is provided on the lower surface of the working tube 11. The slider 10 is slidably disposed inside the right long hole 24.

[0035] The surface of the working airbag 17 is in contact with the surface of the extrusion plate 15, and the upper surface of the working airbag 17 is fixedly connected to the upper pipe 22, and the lower surface of the working airbag 17 is fixedly connected to the lower pipe 23. The upper pipe 22 is connected to the connecting pipe on the lower surface of the working pipe 11 through an external hose, and both the surface of the upper pipe 22 and the surface of the lower pipe 23 are provided with one-way valves.

[0036] During the lateral movement of the working pipe 11, the squeezing plate 15 moves synchronously, thereby intermittently squeezing the working airbag 17. When the working airbag 17 is squeezed, it supplies air to the working pipe 11 through the upper pipe 22 and the external hose. When the working airbag 17 is not squeezed, it draws air through the lower pipe 23 (both the surfaces of the lower pipe 23 and the upper pipe 22 are equipped with one-way valves, so that the working direction of the airflow is from the lower pipe 23 to the working pipe 11). As a result, the working pipe 11 intermittently blows air, which helps to blow away impurities and accelerate their fall, thus optimizing the cleaning effect. During the lateral movement and swinging of the working pipe 11, the protruding part on the surface of the working pipe 11 will drive the squeezing plate 15 to move normally. At the same time, the limiting rod 16 prevents the squeezing plate 15 from swinging, which can apply reasonable pressure to the working airbag 17 and ensure the working efficiency of the working airbag 17.

[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
