Description

Technical Field

[0001] The present invention relates to the technical field of ceiling speakers, and more specifically, to a ceiling speaker. Background Art

[0002] Ceiling speakers are widely used in background music and public address systems in places such as restaurants, teahouses, playgrounds, stations, schools, squares, office buildings, workshops, etc., and are gradually being used in home background music systems.

[0003] However, currently during the installation process of ceiling speakers, the power cord and data cable are connected to the interfaces of the ceiling speaker through screws. If the ceiling speaker needs to be debugged or internal components are damaged, the ceiling speaker needs to be removed, and then the power cord and data cable connected to the ceiling speaker need to be removed in order to completely remove the ceiling speaker from the ceiling for repair. During repeated debugging or repeated repair processes, it is easy to damage the interfaces of the ceiling speaker, and during multiple debugging or multiple repairs, the interfaces of the ceiling speaker will be worn, which will then lead to unstable connections between the interfaces and the power cord and data cable, or problems with loose connections, resulting in situations such as short circuits and power outages or poor signals in the ceiling speaker, increasing the repair cost. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a ceiling speaker.

[0008] Further, a strip hole for the movable plate to slide through is provided on the fixed housing. The size of the installation block is adapted to the size of the installation groove. The bottom of one end of the two clamping blocks close to each other is provided with an inclined surface. The two sides of the top of the pushing rod are provided with inclined surfaces. The two side walls of the pushing rod are made of rubber material.

[0009] Further, a fixing component is provided on the fixed housing. The fixing component includes two activity grooves two provided on both sides of the fixed housing. A fixed shaft is fixedly connected to the inside of each of the two activity grooves two. A rotating cylinder is sleeved on each of the two fixed shafts. A spring two is sleeved on the outer side wall of each of the two fixed shafts. The two ends of each of the two spring two are fixedly connected to the corresponding activity groove two and the rotating cylinder respectively.

[0012] As described above, the beneficial effects of a ceiling-mounted speaker in the present invention are as follows: After quick fixation, the plug is quickly connected to the interface of the ceiling speaker body, enabling power-on and data transmission of the ceiling speaker body, reducing the operation of disconnecting the ceiling speaker body from the power cord and data cable during maintenance, and avoiding wear of the interface of the ceiling speaker body caused by multiple disconnection operations, which affects the connection stability of the power cord and data cable of the ceiling speaker body, preventing situations such as loose connection, improving the effectiveness of power-on and data transmission of the ceiling speaker body, reducing the need for repeated debugging or maintenance, and lowering the maintenance cost; By adjusting the position of the plug, the position of the plug can be adapted to different types of interfaces, avoiding problems where the interface positions are different due to different models of the ceiling speaker body, resulting in the plug being unable to be effectively inserted into the interface for connection, ensuring that the plug can be effectively inserted into the interfaces of ceiling speaker bodies of different sizes. In addition, since the size of the fixing shell is a fixed size, only a tool of a unified size is required to drill holes in the ceiling, without the need to replace tools of different sizes, avoiding problems where installation cannot be carried out due to errors; The fixing shell can be fixed by the deployable fixing rod, and the deployed fixing rod can adapt to ceiling mounting holes of different sizes, avoiding problems where the mounting of the fixing shell becomes loose due to overly large mounting holes. At the same time, by raising the fixing rod and then making it contact the upper surface of the ceiling, the ceiling speaker can be installed on ceilings of different thicknesses, avoiding problems where the fixing shell cannot be installed due to overly thick ceilings, further ensuring the effectiveness of installation, improving the stability of installation, and preventing the ceiling speaker body from falling during long-term use due to insecure installation; By the movable plate contacting the upper surface of the ceiling, the fixing shell is supported, avoiding the situation where the fixing shell falls due to the breakage of the fixing rod and being unable to support it, further improving the stability of the installation of the fixing shell for the subsequent installation of the ceiling speaker body, achieving secondary protection of the fixing shell, and improving the safety of the installation of the fixing shell and the subsequent ceiling speaker body; By releasing the clamping relationship between the clamping block and the clamping groove, the effect of quick disassembly is achieved. Compared with the existing method that requires pulling to remove the ceiling speaker body, this method can reduce the removal time of the ceiling speaker body, and also reduce the use of tools, reduce the cumbersome operation of using tools, and avoid damage to the ceiling when using tools to remove the ceiling speaker body, ensuring the integrity of the ceiling and improving the convenience of removing the ceiling speaker body.

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] The embodiments provided by the present invention will be elaborated in detail below: As Figures 1 to 4 and Figure 7As shown, a ceiling speaker includes a ceiling speaker body 1 and a fixing shell 2. The ceiling speaker body 1 is detachably installed inside the fixing shell 2. An interface for power supply and data transmission is provided on the ceiling speaker body 1. A first sound-absorbing cotton 21 is fixedly connected to the bottom of the fixing shell 2, a second sound-absorbing cotton 22 is fixedly connected to the inner wall of the fixing shell 2, and an adjusting component is arranged at the top of the fixing shell 2. It should be noted that both the first sound-absorbing cotton 21 and the second sound-absorbing cotton 22 are used to weaken the transmission of the sound of the ceiling speaker body 1, prevent the sound from being transmitted to the ceiling through the fixing shell 2, and reduce the noise generated to other residents after the sound is transmitted, thus avoiding disturbing the neighbors.

[0017] The adjusting component includes two adjusting grooves 31 opened at the top of the fixing shell 2. A sliding connection is provided between each of the two adjusting grooves 31 and an adjusting block 32. A plug 33 is fixedly connected to the bottom of each of the two adjusting blocks 32. A connector 34 is fixedly connected to each of the two sides where the adjusting blocks 32 are away from each other. A screw for fixing the power cord and the data cable is provided on each connector 34. By tightening the screw, the data cable and the power cord can be fixed to the connector 34. A movable block 35 is fixedly connected to the top of each of the two adjusting blocks 32. A knob 36 passing through the top surface of the fixing shell 2 is rotatably connected to the top of the fixing shell 2. The bottom of the knob 36 is made of rubber material for convenient rotation. One end of the knob 36 passing through the upper part of the fixing shell 2 is fixedly connected to an adjusting plate 37. The adjusting plate 37 is rotatably connected to the top of the fixing shell 2. Two arc-shaped grooves are opened on the adjusting plate 37. The two movable blocks 35 are respectively slid in the two arc-shaped grooves.

[0018] Such as Figures 1 to 8As shown in the figure, an installation component for fixing the ceiling speaker body 1 is provided on the movable block 35. A connecting rod 41 is fixedly connected to the top of each of the two movable blocks 35. A movable plate 42 is fixedly connected to the bottom of each of the two connecting rods 41. A strip-shaped hole for the movable plate 42 to slide through is formed in the fixed shell 2. One end of each of the two movable plates 42 extending through the side wall of the fixed shell 2 into the interior of the fixed shell 2 is fixedly connected with a limiting plate 43. Installation grooves 44 are formed at the bottoms of the two limiting plates 43. Two clamping grooves 45 are formed inside each of the installation grooves 44. Two limiting grooves 46 are formed on the side wall of the ceiling speaker body 1. Two installation blocks 47 corresponding to the positions of the limiting grooves 46 are fixedly connected to the ceiling speaker body 1. The size of the installation block 47 is adapted to the size of the installation groove 44, and the installation block 47 can be embedded into the installation groove 44. An activity groove one 48 is formed inside each of the two installation blocks 47. The activity groove one 48 is in a cross shape composed of a horizontal groove and a vertical groove. A through groove communicating with the bottom of the vertical groove of the activity groove one 48 is formed on the ceiling speaker body 1. Two clamping blocks 49 are slidably connected to the horizontal groove of the activity groove one 48. The size of the clamping block 49 matches that of the clamping groove 45, and when the installation block 47 is completely embedded into the installation groove 44, the position of the clamping block 49 corresponds to the position of the clamping groove 45. The bottom of the end where the two clamping blocks 49 are close to each other is provided with an inclined surface. A first spring 410 is fixedly connected between the top of each of the two clamping blocks 49 and the groove wall of the activity groove one 48. A pushing rod 411 is slidably connected to the vertical groove inside the activity groove one 48. The two sides of the top of the pushing rod 411 are provided with inclined surfaces. After the inclined surface of the pushing rod 411 abuts against the inclined surface of the clamping block 49, the pushing rod 411 can push the clamping block 49 to move towards both sides inside the activity groove one 48. The bottom of the pushing rod 411 passes through the through groove and extends to the bottom of the ceiling speaker body 1. The two side walls of the pushing rod 411 are made of rubber material.

[0019] As Figure 5 , Figures 7 to 9As shown in the figure, a fixing component for fixing the fixing shell 2 to the ceiling is provided on the fixing shell 2. The fixing component includes two moving slots II 51 opened on both sides of the fixing shell 2. A fixing shaft 52 is fixedly connected to the inside of each of the two moving slots II 51. A rotating cylinder 53 is sleeved on each of the two fixing shafts 52. The rotating cylinder 53 is composed of two circular ring plates and a cylinder fixed between them. A spring II 54 is sleeved on the outer side wall of each of the two fixing shafts 52. The two ends of the two springs II 54 are fixedly connected to the corresponding moving slot II 51 groove wall and the rotating cylinder 53 respectively. A gear 55 is sleeved on the outer surface of the cylinder of each of the two rotating cylinders 53. A fixing rod 56 is fixedly connected to the outer side of each of the two gears 55. The two fixing rods 56 are both arranged in an arc-shaped rod shape. The fixing rod 56 is arranged on the outer side of the fixing shell 2 and can be adapted and fitted to the outer wall of the fixing shell 2, without affecting the insertion of the fixing shell 2 into the installation hole in the ceiling. The gear 55 is located between the two circular ring plates. A toothed ring 57 is meshed between the two gears 55. The toothed ring 57 rotates inside the fixing shell 2. The upper and lower surfaces of the teeth of the toothed ring 57 are respectively attached to the circular ring plates of the two rotating cylinders 53, for limiting the position of the toothed ring 57, so that the toothed ring 57 always maintains a meshing state with the gear 55, and can drive the gear 55 to move upward by pushing the toothed ring 57. The inner side wall of the toothed ring 57 is made of rubber material, which can ensure that the user can effectively push and rotate the toothed ring 57.

[0020] Combined with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The sound-absorbing cotton I 21 is not squeezed and deformed. The adjusting block 32 is at the outermost side of the adjusting slot 31, that is, the two adjusting blocks 32 are in a state of moving away from each other. The moving block 35 is at the outermost side of the arc-shaped slot of the adjusting plate 37, that is, the two moving blocks 35 are in a state of moving away from each other. The moving block 35 makes the moving plate 42 drive the limiting plate 43 to be in a state of fitting with the sound-absorbing cotton II 22 through the connecting rod 41. The pushing rod 411 is at the lowest position. The top inclined surface of the pushing rod 411 is only in contact with the inclined surface of the clamping block 49. The mutually separated ends of the two clamping blocks 49 do not extend out of the moving slot I 48. The clamping block 49 does not compress the spring I 410. The spring II 54 is not compressed by the rotating cylinder 53. The spring II 54 makes the rotating cylinder 53 be at the lowest position of the fixing shaft 52. The fixing rod 56 is in a state of fitting with the outer wall of the fixing shell 2.

[0021] The working state is: On the premise of installing the fixing shell 2, it is necessary to ensure that there is an installation hole on the ceiling. In addition, it is also necessary to ensure that the installation hole has a power cord and a data cable. The power cord is used for power supply, and the data cable is used for transmitting audio data; Before installing the fixed shell 2, the power cord and the data cable are installed on the connector 34 by means of screws, and then the knob 36 is rotated, and the knob 36 drives the adjusting plate 37 to rotate. The adjusting plate 37 causes the movable block 35 to drive the adjusting block 32 to approach each other inside the adjusting slot 31 through the arc groove. When the movable block 35 moves, the movable plate 42 drives the limiting plate 43 to approach each other through the connecting rod 41, so that the ends of the connecting rod 41 and the movable plate 42 away from the limiting plate 43 gradually approach the outer surface of the fixed shell 2. When the end of the connecting rod 41 away from the movable block 35 is in contact with the outer surface of the fixed shell 2, the connecting rod 41 and the limiting plate 43 at this time will not affect the insertion of the fixed shell 2 into the mounting hole of the ceiling.

[0022] The fixing assembly fixes the fixing housing 2 to the ceiling: At present, the installation of the ceiling speaker body 1 mostly adopts components such as torsion spring buckles. The torsion spring buckles are against the upper surface of the ceiling, so that the ceiling speaker body 1 can be effectively buckled on the ceiling. However, if the mounting hole of the ceiling is too large, the torsion spring buckle will not be able to contact the upper surface of the ceiling, resulting in the ceiling speaker body 1 being unable to be effectively buckled on the ceiling, or a single torsion spring buckle will not be able to contact the upper surface of the ceiling, resulting in the installation of the ceiling speaker body 1 being crooked, affecting the installation of the ceiling speaker body 1. The ceiling speaker body 1 is also fixed to the ceiling by screws, which will also cause the above-mentioned problems. If the mounting hole of the ceiling is too large, the screws will not be effectively threaded with the ceiling, which will also cause the ceiling speaker body 1 to be installed loosely. Because the speaker of the ceiling speaker body 1 will vibrate when playing music, it is easy to cause the ceiling speaker body 1 to fall off. If the ceiling speaker body 1 falls off, it will cause the ceiling speaker body 1 to be broken or injure passers-by, thereby causing safety hazards.

[0023] The open end of the fixed shell 2 is in a downward state, and then the user inserts the fixed shell 2 into the installation hole of the ceiling. At this time, the bottom of the fixed shell 2 is in a fit with the bottom of the ceiling, that is, the sound-absorbing cotton 21 is still exposed outside the ceiling installation hole. Then the user extends his hand into the interior of the fixed shell 2 and pushes the gear ring 57 again, so that the gear ring 57 moves upward inside the fixed shell 2. Because the teeth of the gear ring 57 are in conflict with the circular ring plate of the rotating cylinder 53, the gear ring 57 will push the rotating cylinder 53 to move upward on the outer surface of the fixed shaft 52 during the upward movement of the gear ring 57, and the rotating cylinder 53 will compress the spring 2 54. At this time, when the rotating cylinder 53 moves upward, it will drive the fixed rod 56 to move upward synchronously through the gear 55. Then the user rotates the gear ring 57, and the gear ring 57 will drive the gear 55 to rotate on the rotating cylinder 53. The gear 55 will drive the fixed rod 56 to rotate to the side away from the outer surface of the fixed shell 2, and the two fixed rods 56 will spread outward. The gear ring 57 is then loosened, and the rotating cylinder 53 moves downward on the outer surface of the rotating cylinder 53 under the elastic restoring action of the spring 2 54. The rotating cylinder 53 will drive the fixing rod 56 to move downward synchronously through the gear 55, so that the fixing rod 56 hits the upper surface of the ceiling. At this time, the installation of the fixed shell 2 is completed, and the fixing shell 2 can be fixed by the deployable fixing rod 56, and the deployed fixing rod 56 can adapt to ceiling mounting holes of different sizes, so as to avoid the problem of loose installation of the fixed shell 2 due to the mounting hole being too large. At the same time, by lifting the fixing rod 56 and then making the fixing rod 56 hit the upper surface of the ceiling, the speaker can be installed on ceilings of different thicknesses, so as to avoid the problem of the fixed shell 2 being unable to be installed due to the ceiling being too thick, thereby further ensuring the effectiveness of the installation, improving the stability of the installation, and avoiding the situation where the ceiling speaker body 1 falls off due to long-term use due to loose installation.

[0024] At this time, the knob 36 is rotated in the opposite direction, and the knob 36 drives the adjustment plate 37 to rotate in the opposite direction. The adjustment plate 37 makes the two movable blocks 35 drive the two adjustment blocks 32 away from each other through the arc groove, wherein the two movable blocks 35 will make the connecting rod 41 drive the two limit plates 43 away from each other through the movable plate 42. At this time, the movable plate 42 will protrude from the outer surface of the fixed shell 2. When someone maliciously pulls and removes the fixed shell 2, or when the fixed rod 56 is broken and the fixed shell 2 cannot be fixed, when the fixed shell 2 is pulled, the fixed shell 2 moves downward in the mounting hole of the ceiling, and the movable plate 42 will move downward synchronously with the fixed shell 2. At this time, the movable plate 42 will contact the upper surface of the ceiling, and then support the fixed shell 2, avoiding the situation that the fixed rod 56 cannot support the fixed shell 2 after it breaks and causes it to fall, further improving the stability of the subsequent installation of the ceiling speaker body 1 after the fixed shell 2 is installed, realizing secondary protection of the fixed shell 2, and improving the safety of the fixed shell 2 and the subsequent ceiling speaker body 1 after installation.

[0025] The adjustment component adapts to ceiling speakers of different models 1: When ceiling speakers of different models 1 need to be installed on the ceiling, that is, ceiling speakers 1 of different sizes. If ceiling speakers 1 of different sizes are installed and only hole drilling tools of different sizes can be used to drill holes in the ceiling during the current hole drilling process, any mistakes during the busy construction process, such as the installation holes being too small or too large, will lead to the problem that the ceiling speakers 1 cannot be installed; By rotating the knob 36, the knob 36 drives the adjustment plate 37 to rotate. The adjustment plate 37 makes the movable block 35 drive the adjustment block 32 to slide inside the adjustment groove 31 through the arc-shaped groove. The adjustment block 32 drives the plug 33 to move horizontally synchronously. By adjusting the position of the plug 33, the position of the plug 33 can adapt to interfaces of different models, avoiding the problem that the plug 33 cannot be effectively inserted into the interface due to different interface positions caused by different models of the ceiling speakers 1, ensuring that the plug 33 can be effectively inserted into the interfaces of ceiling speakers 1 of different sizes. In addition, since the size of the fixed shell 2 is a fixed size, only tools of a unified size are needed to drill holes in the ceiling, without the need to replace hole drilling tools of different sizes, avoiding the problem of being unable to install due to mistakes.

[0026] The installation component quickly fixes the ceiling speaker body 1 inside the fixed shell 2: During the current installation process of the ceiling speaker body 1, the power cord and data cable are directly connected to the ceiling speaker body 1. If the ceiling speaker body 1 needs to be debugged or internal components are damaged, the ceiling speaker body 1 needs to be removed, and then the power cord and data cable connected to the ceiling speaker body 1 need to be removed. During repeated debugging or repeated maintenance, it is easy to damage the interfaces of the ceiling speaker body 1, and during multiple debugging or multiple maintenance, the interfaces of the ceiling speaker body 1 will be worn, which will then lead to unstable connections between the interfaces and the power cord and data cable, or loose connection problems, resulting in situations such as short circuits and power outages or poor signals in the ceiling speaker body 1, thus requiring repairs to the ceiling speaker body 1 and increasing the repair cost.

[0027] The user inserts the ceiling-mounted speaker body 1 to be installed into the inside of the fixing shell 2. At this time, align the limiting groove 46 with the limiting plate 43, and during the upward movement of the ceiling-mounted speaker body 1, the limiting plate 43 can slide in the limiting groove 46. When the ceiling-mounted speaker body 1 moves upward in the fixing shell 2, under the limiting effect of the limiting plate 43 and the limiting groove 46, the ceiling-mounted speaker body 1 can move upward smoothly. When the ceiling-mounted speaker body 1 moves upward, it will drive the mounting block 47 to move synchronously. At this time, the mounting block 47 gradually embeds into the inside of the mounting groove 44. When the mounting block 47 is completely embedded into the inside of the mounting groove 44, the clamping block 49 and the clamping groove 45 are in a horizontally coincident state. Then the user presses the pushing rod 411 again, so that the pushing rod 411 moves upward inside the first movable groove 48. The pushing rod 411 pushes the inclined surface of the clamping block 49 through the inclined surface on it, so that the clamping block 49 moves to both sides. At this time, the clamping block 49 will move into the inside of the clamping groove 45. When the clamping block 49 moves, it will compress the first spring 410. When the clamping block 49 moves into the inside of the clamping groove 45, a clamping relationship is formed. Through the clamping of the clamping block 49 and the clamping groove 45, the ceiling-mounted speaker body 1 is quickly fixed. After being quickly fixed, the plug 33 is quickly connected to the interface of the ceiling-mounted speaker body 1, realizing the power-on and data transmission of the ceiling-mounted speaker body 1, reducing the operation of disconnecting the ceiling-mounted speaker body 1 from the power cord and data cable during maintenance, avoiding the wear of the interface of the ceiling-mounted speaker body 1 caused by multiple disconnection operations, affecting the connection stability of the power cord and data cable of the ceiling-mounted speaker body 1, avoiding situations such as loose connection, improving the effectiveness of power-on and data transmission of the ceiling-mounted speaker body 1, reducing the situations that need to be repeatedly debugged or repaired, and reducing the maintenance cost.

[0028] In addition, after the pushing rod 411 moves upward, the two side walls of the pushing rod 411 will respectively abut against the mutually approaching ends of the two clamping blocks 49. And under the elastic reset action of the cooperation of the first spring 410, the clamping block 49 tightly abuts against the pushing rod 411. At the same time, since the two side walls of the pushing rod 411 are made of rubber material, after the clamping block 49 abuts against the two side walls of the pushing rod 411, due to the large frictional force, the problem of the pushing rod 411 falling downward can be avoided, and the pushing rod 411 can make the clamping block 49 and the clamping groove 45 be stably clamped.

[0029] It should be noted that after the ceiling-mounted speaker body 1 moves downward, the ceiling-mounted speaker body 1 also always maintains the abutting state with the first sound-absorbing cotton 21. At the same time, after the ceiling-mounted speaker body 1 moves downward, it will not affect the connection relationship between the plug 33 and the interface on the ceiling-mounted speaker body 1, and can also power on and transmit data to the ceiling-mounted speaker body 1.

[0030] Demolish the ceiling-mounted speaker body 1: Since the existing ceiling speakers 1 are all installed on the ceiling through torsion spring fasteners, the current removal method is to directly pull the ceiling speaker 1 downward, causing the torsion spring fastener to flip upward, thus changing the installation relationship between the ceiling speaker 1 and the ceiling. However, during this process, the repairman's hand needs to be inserted into the gap between the ceiling speaker 1 and the ceiling. This operation is rather troublesome and requires the assistance of tools. Using tools is likely to damage the ceiling. At the same time, the flipped torsion spring fastener will also cause friction on the edge of the installation hole in the ceiling when the repairman pulls, resulting in damage to the installation hole in the ceiling, which is not conducive to the reinstallation of the ceiling speaker 1 later. In addition, the installation method using screws also requires the assistance of tools to remove the ceiling speaker 1, which is also rather troublesome.

[0031] The user pulls and squeezes the push rod 411 forcefully, causing the push rod 411 to move downward inside the first movable slot 48. After the push rod 411 moves downward, it no longer squeezes the latch 49. Under the elastic reset action of the first spring 410, the two latches 49 move toward the inside of the first movable slot 48. At this time, the latch 49 no longer maintains a clamping relationship with the clamping groove 45. After the user pulls the ceiling speaker 1, the ceiling speaker 1 can be quickly removed. By releasing the clamping relationship between the latch 49 and the clamping groove 45, the effect of quick disassembly is achieved. Compared with the existing method that requires pulling to remove the ceiling speaker 1, this method can reduce the removal time of the ceiling speaker 1, and at the same time reduce the use of tools, simplify the cumbersome operation of using tools, and also avoid damaging the ceiling when using tools to remove the ceiling speaker 1, ensuring the integrity of the ceiling and improving the convenience of removing the ceiling speaker 1.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
