[0008] The threaded component includes a screwing head positioned below the edge of the ring and a fixing post fixedly installed above the screwing head. A spiral post is fixedly installed above the fixing post, and the upper end of the spiral post is movably connected to an L-shaped hanging member. A force measuring rod member is rotatably installed inside the L-shaped hanging member, and the end of the force measuring rod member is located outside the L-shaped hanging member.

[0012] Preferably, a component groove is formed inside the L-shaped hanging member. The force measuring rod member is rotatably installed inside the component groove, and a driven rotation assembly and a pressure testing assembly are also installed inside the component groove.

[0013] Preferably, the driven rotation assembly includes a connecting shaft end face gear movably installed inside the component groove and a rotating end face gear meshed and installed on one side of the connecting shaft end face gear. The rotating end face gear is fixedly connected to the outside of the cylindrical member through a shaft. The connecting shaft end face gear is connected to a driven gear through a shaft, and the driven gear meshes with the fixed half gear.

[0014] Preferably, the meshing position of the connecting shaft end face gear and the rotating end face gear is arranged towards the outside of the component groove.

[0017] Preferably, a force measuring sensor is fixedly installed inside the fixed block, and the force measuring sensor is in contact with one end of the force measuring spring.

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

[0019] 1. A ceiling-mounted speaker according to the present invention is provided with a rotating structure for a force-measuring rod inside an L-shaped hanging member, such that one end of the force-measuring rod contacts the ceiling. A pressure-sensing structure can be provided at the other end of the force-measuring rod. When the speaker box damages the ceiling, it will cause a change in the horizontal height of the entire speaker box, thereby changing the state of the contact between one end of the force-measuring rod and the ceiling to a state of abutment. At this time, the pressure-sensing structure at the other end of the force-measuring rod will sense the pressure, indicating that the ceiling is damaged.

[0020] 2. A ceiling-mounted speaker according to the present invention, when the spiral column descends in a spiral manner, it will drive the L-shaped hanging member to descend until the fixed half-gear meshes with the driven gear. During the process of the driven gear passing through the fixed half-gear, the driven gear will drive the coupling end-face gear and the rotating end-face gear to rotate. The rotating rotating end-face gear will drive the cylindrical member, the pressure spring, and the rod to rotate. At this time, one end of the rod rotates downward until it contacts above the ceiling, enabling the pressure test assembly to sense a slight pressure. During the installation of the speaker box, the rod rotates, achieving the purpose of rotating the rod through a mechanical structure and simplifying the operation means.

[0021] 3. A ceiling-mounted speaker according to the present invention detects the damage of the ceiling through pressure changes. When the ceiling is damaged, its thickness becomes thinner. At this time, the overall horizontal height of the speaker box will decrease, and one end of the rod changes from a contact state to an abutment state, that is, the rod also follows the decrease in the horizontal height of the speaker box. At this time, the rod will slide inside the cylindrical member, and one end of the rod will again push the lifting block, reducing the distance between the lifting block and the fixed block. The force-measuring spring will be compressed. At this time, the force-measuring sensor senses a new pressure, and the magnitude of the pressure value represents the damage condition of the ceiling. When the pressure values sensed by the force-measuring sensors provided in multiple L-shaped hanging members are different, it means that the ceiling is not in a horizontal state, that is, it also indicates that the ceiling is damaged, which helps to detect and handle in a timely manner, thereby improving the use effect of the speaker.

Specific embodiments

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. Embodiment 1

[0032] As Figure 1-3 shown, a ceiling-mounted speaker of an embodiment of the present invention includes a speaker box body 2, a speaker is provided inside the speaker box body 2, a circular ring edge 1 is fixedly installed below the speaker box body 2, a plurality of installation grooves 3 are fixedly opened on the outside of the speaker box body 2, and an L-shaped hanging member 4 is movably installed inside the installation groove 3;

[0033] The threaded component 5 includes a screwing head 51 located below the circular ring edge 1 and a fixing column 52 fixedly installed above the screwing head 51. A spiral column 53 is fixedly installed above the fixing column 52, the upper end of the spiral column 53 is movably connected to the L-shaped hanging member 4, and a force measuring rod 6 is rotatably installed inside the L-shaped hanging member 4, and the end of the force measuring rod 6 is located outside the L-shaped hanging member 4.

[0034] Specifically, first use a tool to make a circular hole in the ceiling, and embed the speaker box 2 into this circular hole. Since the diameter of the ring edge 1 is greater than the diameter of the speaker box 2, at this time the speaker box 2 is above the ceiling, while the ring edge 1 is below the ceiling, and the upper side of the ring edge 1 is in contact with the lower side of the ceiling. When it is necessary to fix the connection between the speaker box 2 and the ceiling, use a tool such as a screwdriver to drive the screwing head 51 to rotate, thereby driving the fixing column 52, the spiral column 53 and the L-shaped hanging member 4 to rotate until the L-shaped hanging member 4 faces the outside of the speaker box 2 and contacts the inner wall of the installation groove 3. Then, while rotating the screwing head 51, pull it downwards so that the spiral column 53 is screwed to the installation groove 3. At this time, the L-shaped hanging member 4 descends while maintaining the state of facing the outside of the speaker box 2 until the end of the L-shaped hanging member 4 contacts above the ceiling, that is, at this time the ceiling is located between the ring edge 1 and the end of the L-shaped hanging member 4. Under the action of multiple L-shaped hanging members 4, the speaker box 2 is hoisted on the ceiling. The speaker box 2 itself has a certain weight, and when the speaker box 2 is in use, it will generate vibrations. 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 provided inside the L-shaped hanging member 4, so that one end of the force-measuring rod 6 contacts the ceiling, and a structure for sensing pressure can be provided at the other end of the force-measuring rod 6. After the speaker box 2 causes damage to the ceiling, it will drive the horizontal height of the entire speaker box 2 to change, thereby changing the state of one end of the force-measuring rod 6 from contacting the ceiling to abutting against the ceiling. At this time, the structure for sensing pressure at the other end of the force-measuring rod 6 will sense the pressure, thereby indicating that the ceiling is damaged. When the pressure value reaches a certain range, it means that the ceiling will no longer be able to withstand the weight of the speaker box 2, and the ceiling needs to be repaired.

[0035] As Figure 2 shown, the installation groove 3 includes a hidden groove 31 opened inside the speaker box 2 and an L-shaped groove 32. A fixed half gear 33 is fixedly installed on one inner wall of the L-shaped groove 32.

[0036] Specifically, the position of the L-shaped hanging member 4 is inside the L-shaped groove 32, the end position of the force-measuring rod 6 is inside the hidden groove 31, the screwing head 51 is screwed inside the vertical position of the L-shaped groove 32, and the hidden groove 31 and the L-shaped groove 32 are used to hide the force-measuring rod 6 and the L-shaped hanging member 4, which is convenient for the speaker box 2 to be embedded into the ceiling round hole.

[0037] As 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 outside the rod body 61. One side of the cylindrical member 62 is fixedly installed with a compression spring 63. One end of the compression spring 63 is fixedly connected to the outside of the rod body 61. Round head blocks 64 are fixedly installed at both ends of the rod body 61.

[0038] Specifically, when the rotating structure drives the rod body 61 to rotate, the rod body 61 rotates with the mid-section position of the cylindrical member 62 as the center until one end of the rod body 61 contacts above the ceiling. A compression spring 63 is installed between the cylindrical member 62 and the rod body 61. In the natural state of the compression spring 63, the rod body 61 will not slide inside the cylindrical member 62.

[0039] As Figure 4-6 shown, a component groove 41 is formed inside the L-shaped hanging member 4. The force-measuring rod 6 is rotatably installed inside the component groove 41. A driven rotating assembly 7 and a pressure testing assembly 8 are also installed inside the component groove 41. The driven rotating assembly 7 includes a connecting shaft 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 connecting shaft end face gear 72. The rotating end face gear 73 is fixedly connected to the outside of the cylindrical member 62 through a shaft. The connecting shaft end face gear 72 is connected to a driven gear 71 through a shaft. The driven gear 71 meshes with the fixed half gear 33. The meshing position of the connecting shaft end face gear 72 and the rotating end face gear 73 faces the outside of the component groove 41.

[0040] Specifically, the driven rotating assembly 7 is used for the rotation of the rod body 61, and the pressure testing assembly 8 is used to sense the pressure transmitted by one end of the rod body 61. When the screwing 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. At this time, the L-shaped hanging member 4 faces the outside of the speaker box 2. The spiral descent of the spiral column 53 will drive the L-shaped hanging member 4 to descend until the fixed half gear 33 meshes with the driven gear 71. When the driven gear 71 passes through the fixed half gear 33, the driven gear 71 will drive the connecting shaft end face gear 72 and the rotating end face gear 73 to rotate. The rotating rotating end face gear 73 will drive the cylindrical member 62, the compression 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 above the ceiling, so that the pressure testing assembly 8 senses a slight pressure. During the installation of the speaker box 2, the rod body 61 is rotated, and the purpose of rotating the rod body 61 is achieved through a mechanical structure, and the operation means is simplified. Embodiment Two

[0041] As 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, and 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, and 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, and one end of the force measuring spring 812 is fixedly connected to one side of the lifting block 81. A force sensor 821 is fixedly installed inside the fixed block 82, and the force sensor 821 is in contact with one end of the force measuring spring 812.

[0042] 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 spring 812. At this time, the force 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 too long, 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 61 will slide inside the cylindrical part 62, and one end of the rod 61 will push the lifting block 81 again, reducing the distance between the lifting block 81 and the fixed block 82. The force spring 812 will be compressed. At this time, the force sensor 821 feels the 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.

[0043] Working principle: First, use a tool to drill a circular hole in the ceiling, and embed the speaker box body 2 into this circular hole. Since the diameter of the circular ring edge 1 is greater than the diameter of the speaker box body 2, at this time, the speaker box body 2 is above the ceiling, while the circular ring edge 1 is below the ceiling, and the upper side of the circular ring edge 1 is in contact with the lower side of the ceiling. When it is necessary to fix the connection between the speaker box body 2 and the ceiling, drive the screwing head 51 to rotate through tools such as a screwdriver, and then drive the fixing column 52, the spiral column 53, and the L-shaped hanging member 4 to rotate until the L-shaped hanging member 4 faces the outside of the speaker box body 2 and is in contact with the inner wall of the installation groove 3. Then, while rotating the screwing head 51, pull it downwards so that the spiral column 53 is screwed to the installation groove 3. At this time, the L-shaped hanging member 4 descends while maintaining the state of facing the outside of the speaker box body 2 until the end of the L-shaped hanging member 4 contacts the upper side of the ceiling, that is, at this time, the ceiling is located between the circular ring edge 1 and the end of the L-shaped hanging member 4. Under the action of multiple L-shaped hanging members 4, the speaker box body 2 is hoisted on the ceiling. The speaker box body 2 itself has a certain weight, and when the speaker box body 2 is in use, it will generate vibrations. Under these two factors, the speaker box body 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 member 6 is provided inside the L-shaped hanging member 4, so that one end of the force-measuring rod member 6 contacts the ceiling, and a structure for sensing pressure can be provided at the other end of the force-measuring rod member 6. After the speaker box body 2 causes damage to the ceiling, it will drive the overall horizontal height of the entire speaker box body 2 to change, and then the state of one end of the force-measuring rod member 6 changing from contact with the ceiling to being in contact with it. At this time, the structure for sensing pressure at the other end of the force-measuring rod member 6 will sense the pressure, indicating that the ceiling is damaged. When the pressure value reaches a certain range, it means that the ceiling will no longer be able to withstand the weight of the speaker box body 2, and the ceiling needs to be repaired. After 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 sense a slight pressure, and this pressure value indicates the intact condition of the ceiling when the speaker box body 2 is initially installed. After the speaker box body 2 has been used for a long time, under the influence of vibration and gravity, it 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 decrease, and one end of the rod body 61 changes from the contact state to the contact state, that is, the rod body 61 also follows the decrease in the horizontal height of the speaker box body 2. At this time, the rod body 61 will slide inside the cylindrical member 62, and one end of the rod body 61 will act on the lifting block 81 again to push it, reducing the distance between the lifting block 81 and the fixed block 82. The force-measuring spring 812 will be compressed, and at this time, the force-measuring sensor 821 senses a new pressure, and the magnitude of the pressure value represents the damaged condition of the ceiling. When the pressure values sensed by the force-measuring sensors 821 provided in multiple L-shaped hanging members 4 are different,It represents that the ceiling is not in a horizontal state, which also indicates that the ceiling is damaged.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention.
