DETAILED DESCRIPTION

[0023] 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. Embodiment 1

[0024] like Figure 1-3 As shown, a ceiling speaker of an embodiment of the present invention comprises a speaker box 2, a speaker is arranged inside the speaker box 2, a circular edge 1 is fixedly installed below the speaker box 2, a plurality of installation grooves 3 are fixedly opened on the outer side of the speaker box 2, and an L-shaped hanging member 4 is movably installed inside the installation groove 3; The threaded assembly 5 includes a screw head 51 located below the circular ring edge 1 and a fixed column 52 fixedly installed above the screw head 51. A spiral column 53 is fixedly installed above the fixed column 52. The upper end of the spiral column 53 is movably connected to the L-shaped hanging component 4. A force measuring rod 6 is rotatably installed inside the L-shaped hanging component 4, and the end of the force measuring rod 6 is located on the outside of the L-shaped hanging component 4.

[0025] Specifically, a circular hole is first made on the ceiling using a tool, and the speaker box 2 is embedded in the circular hole. Because the diameter of the circular edge 1 is larger than the diameter of the speaker box 2, the speaker box 2 is above the ceiling at this time, while the circular edge 1 is below the ceiling, and the upper side of the circular edge 1 is in contact with the bottom of the ceiling. When it is necessary to fix the connection between the speaker box 2 and the ceiling, the screw head 51 is driven to rotate by a screwdriver or other tool, thereby driving the fixing column 52, the spiral column 53 and the L-shaped hanging piece 4 to rotate until the L-shaped hanging piece 4 faces the outside of the speaker box 2 and contacts the inner wall of the installation groove 3. The screw head 51 is then rotated and pulled down at the same time, so that the spiral column 53 is spirally connected to the installation groove 3. At this time, the L-shaped hanging piece 4 remains facing the outside of the speaker box 2 and descends until the end of the L-shaped hanging piece 4 contacts the top of the ceiling, that is, at this time the ceiling is between the circular edge 1 and the end of the L-shaped hanging piece 4. Under these two factors, the speaker box 2 is hung on the ceiling. The speaker box 2 itself has a certain weight, and the speaker box 2 will vibrate when in use. Under these two factors, the speaker box 2 used for a long time will cause certain damage to the ceiling. In the prior art, it is not easy to detect this situation. At this time, a rotating structure for the force measuring rod 6 is set inside the L-shaped hanging part 4, so that one end of the force measuring rod 6 is in contact with the ceiling, and a structure for sensing pressure can be set at the other end of the force measuring rod 6. When the speaker box 2 causes damage to the ceiling, the horizontal height of the entire speaker box 2 will be changed, and then one end of the force measuring rod 6 and the ceiling will change from a contact state to a conflict state. At this time, the structure for sensing pressure at the other end of the force measuring rod 6 will feel pressure, indicating that the ceiling is damaged. When the pressure value reaches a certain range, it means that the ceiling will not be able to withstand the weight of the speaker box 2 and the ceiling needs to be repaired.

[0026] like Figure 2 As shown, the installation slot 3 includes a hidden slot 31 and an L-shaped slot 32 opened inside the speaker box 2, and a fixed half gear 33 is fixedly installed on the inner wall of one side of the L-shaped slot 32.

[0027] Specifically, the L-shaped hanging component 4 is located inside the L-shaped groove 32, the end position of the force measuring rod 6 is located inside the hidden groove 31, and the screw head 51 is spirally connected inside the vertical position of the L-shaped groove 32. The hidden groove 31 and the L-shaped groove 32 are used to hide the force measuring rod 6 and the L-shaped hanging component 4, so as to facilitate the speaker box 2 to be embedded into the circular hole of the ceiling.

[0028] like Figure 6As shown, the force measuring rod 6 includes a rod body 61 and a cylindrical member 62 rotatably installed inside the L-shaped hanging member 4, the cylindrical member 62 is sleeved on the outside of the rod body 61, a pressure spring 63 is fixedly installed on one side of the cylindrical member 62, one end of the pressure spring 63 is fixedly connected to the outside of the rod body 61, and round head blocks 64 are fixedly installed at both ends of the rod body 61.

[0029] Specifically, when the rotating structure drives the rod body 61 to rotate, the rod body 61 is rotated with the middle section of the cylindrical member 62 as the center until one end of the rod body 61 contacts the top of the ceiling. A pressure spring 63 is installed between the cylindrical member 62 and the rod body 61. When the pressure spring 63 is in a natural state, the rod body 61 will not slide inside the cylindrical member 62.

[0030] like Figure 4-6 As shown, a component groove 41 is opened inside the L-shaped hanging part 4, and the force measuring rod 6 is rotatably installed inside the component groove 41. A driven rotating component 7 and a pressure testing component 8 are also installed inside the component groove 41. The driven rotating component 7 includes a coupling end face gear 72 movably installed inside the component groove 41, and a rotating end face gear 73 meshingly installed on one side of the coupling end face gear 72. The rotating end face gear 73 is fixedly connected to the outer side of the cylindrical part 62 through a shaft. The coupling end face gear 72 is connected to a driven gear 71 through a shaft. The driven gear 71 is meshed with the fixed half gear 33, and the meshing position of the coupling end face gear 72 and the rotating end face gear 73 is set toward the outer side of the component groove 41.

[0031] Specifically, the driven rotating assembly 7 is used for rotating the rod body 61, and the pressure testing assembly 8 is used for sensing the pressure transmitted by one end of the rod body 61. When the screw head 51 drives the L-shaped hanging member 4 to rotate until the L-shaped hanging member 4 contacts the inner wall of one side of the L-shaped groove 32, the L-shaped hanging member 4 faces the outside of the speaker box 2, and the spiral descent of the spiral column 53 drives the L-shaped hanging member 4 to descend until the fixed half gear 33 is meshed with the driven gear 71. In the process of passing through the fixed half gear 33, the driven gear 71 is The moving gear 71 will drive the coupling end gear 72 and the rotating end gear 73 to rotate, and the rotating rotating end gear 73 will drive the cylindrical member 62, the pressure spring 63 and the rod body 61 to rotate. At this time, one end of the rod body 61 rotates downward until this end contacts the top of the ceiling, allowing the pressure test assembly 8 to feel a slight pressure. During the installation of the speaker box 2, the rod body 61 is rotated. The purpose of rotating the rod body 61 is achieved through a mechanical structure, and the means of operation are simplified. Embodiment 2

[0032] like Figure 7As shown, compared with Example 1, another embodiment of the present invention is: the pressure testing assembly 8 includes a fixed block 82 fixedly installed at the top of the component groove 41, a lifting block 81 is movably installed below the fixed block 82, the lifting block 81 is located above one end of the force measuring rod 6, a plurality of guide columns 811 are fixedly installed on one side of the lifting block 81, one end of the plurality of guide columns 811 is slidably installed inside the fixed block 82, a force measuring spring 812 is fixedly installed at a spacing position between the lifting block 81 and the fixed block 82, one end of the force measuring spring 812 is fixedly connected to one side of the lifting block 81, a force measuring sensor 821 is fixedly installed inside the fixed block 82, and the force measuring sensor 821 is in contact with one end of the force measuring spring 812.

[0033] Specifically, when the rod body 61 rotates, a round head block 64 will press against the lower side of the lifting block 81, thereby slightly compressing the force measuring spring 812. At this time, the force measuring sensor 821 will feel a slight pressure. This pressure value indicates the integrity of the ceiling when the speaker box 2 is first installed. When the speaker box 2 has been used for a long time, the vibration and gravity factors will cause damage to the ceiling. When the ceiling is damaged, its thickness will become thinner. At this time, the overall horizontal height of the speaker box 2 will drop, and one end of the rod body 61 will change from a contact state to a resistance state, that is, the rod body 61 will also As the horizontal height of the speaker box 2 drops, the rod body 61 will slide inside the cylindrical part 62, and one end of the rod body 61 will push the lifting block 81 again, reducing the distance between the lifting block 81 and the fixed block 82. The force measuring spring 812 will be compressed. At this time, the force sensor 821 feels new pressure. The size of the pressure value represents the damage of the ceiling. When the pressure values ​​of the force sensors 821 set in multiple L-shaped hanging parts 4 are different, it means that the ceiling is not in a horizontal state, which also indicates that the ceiling is damaged, and this is not conducive to the playback sound quality of the speaker box 2.

[0034] Working principle: first use a tool to make a circular hole in the ceiling, and embed the speaker box 2 into the circular hole. Because the diameter of the circular edge 1 is larger than the diameter of the speaker box 2, the speaker box 2 is above the ceiling, and the circular edge 1 is below the ceiling, and the upper side of the circular edge 1 is in contact with the bottom of the ceiling. When it is necessary to fix the connection between the speaker box 2 and the ceiling, use a screwdriver or other tool to drive the screw head 51 to rotate, thereby driving the fixing column 52, the spiral column 53 and the L-shaped hanging part 4 to rotate until the L-shaped hanging part 4 faces the outside of the speaker box 2 and contacts the inner wall of the installation groove 3, and then rotate the screw head 51 while pulling it down to allow the spiral column 53 to be spirally connected to the installation groove 3. At this time, the L-shaped hanging part 4 The speaker cabinet 2 is kept downwardly moved toward the outside of the speaker cabinet 2 until the end of the L-shaped hanging piece 4 contacts the top of the ceiling, that is, at this time the ceiling is between the circular edge 1 and the end of the L-shaped hanging piece 4. The speaker cabinet 2 is hung on the ceiling by the action of multiple L-shaped hanging pieces 4. The speaker cabinet 2 itself has a certain weight, and the speaker cabinet 2 will vibrate when in use. Under these two factors, the speaker cabinet 2 used for a long time will cause certain damage to the ceiling. In the prior art, this situation cannot be easily detected. At this time, a rotating structure for a force measuring rod 6 is provided inside the L-shaped hanging piece 4, so that one end of the force measuring rod 6 contacts the ceiling, and a pressure sensing member can be provided at the other end of the force measuring rod 6. The structure of force, when the speaker box 2 causes damage to the ceiling, the horizontal height of the entire speaker box 2 will change, and then one end of the force measuring rod 6 will change from a contact state with the ceiling to a resistance state. At this time, the structure at the other end of the force measuring rod 6 that is used to feel the pressure will feel the pressure, indicating that the ceiling is damaged. When the pressure value reaches a certain range, it means that the ceiling will not be able to withstand the weight of the speaker box 2, and the ceiling needs to be repaired. After the rod 61 rotates, a round head block 64 will press against the lower side of the lifting block 81, thereby slightly compressing the force measuring spring 812. At this time, the force measuring sensor 821 will feel a slight pressure. This pressure value indicates the integrity of the ceiling when the speaker box 2 is first installed. After the box body 2 has been used for a long time, the vibration and gravity factors will cause damage to the ceiling. When the ceiling is damaged, its thickness will become thinner. At this time, the overall horizontal height of the speaker box body 2 will drop, and one end of the rod body 61 will change from a contact state to a resistance state, that is, the rod body 61 will also drop with the horizontal height of the speaker box body 2. At this time, the rod body 61 will slide inside the cylindrical part 62, and one end of the rod body 61 will play a role in pushing the lifting block 81 again, reducing the distance between the lifting block 81 and the fixed block 82, and the force measuring spring 812 will be compressed. At this time, the force sensor 821 feels the new pressure, and the size of the pressure value represents the damage to the ceiling. When the pressure values ​​of the force sensors 821 set in the multiple L-shaped hanging parts 4 are different,This means that the ceiling is not level, which means that the ceiling is damaged.
