Description

Technical Field

[0001] This application relates to the field of ceiling speakers, and in particular to multi-point Bluetooth ceiling speakers. Background Technology

[0002] Ceiling speakers are audio devices installed embedded in the ceiling, primarily used for background music and public address systems in public places and homes. Based on functional requirements, ceiling speakers are divided into three types: standard ceiling speakers, coaxial ceiling speakers, and adjustable bass / treble ceiling speakers. Coaxial ceiling speakers and those with adjustable bass / treble drivers generally offer better sound quality. Their output formats include constant impedance and constant voltage. When purchasing, factors such as energy efficiency, functional compatibility, and installation flexibility should be considered. Ceiling speakers are widely used in background music and public address systems in restaurants, teahouses, playgrounds, train stations, schools, squares, office buildings, and workshops, and are gradually entering home use. Due to structural limitations, these speakers have a weaker bass response, making them more suitable for broadcasting or background music playback than high-fidelity music enjoyment.

[0003] The existing ceiling-mounted speakers require drilling holes in the ceiling, inserting the speaker housing into the holes, securing it with screws, and then installing the speaker into the housing. This cumbersome installation process reduces efficiency. Utility Model Content

[0004] To address the aforementioned issues, this application provides a multi-point Bluetooth ceiling speaker.

[0005] The multi-point Bluetooth ceiling speaker provided in this application adopts the following technical solution:

[0006] A multi-point Bluetooth ceiling speaker includes a speaker body and a mounting shell. The mounting shell is provided with a fixing component, which includes multiple fixing blocks fixedly connected to the upper side wall of the mounting shell. A spring is fixedly connected to the lower surface of the fixing block, and a movable block is fixedly connected to the bottom end of the spring. A support plate is hinged to the lower surface of the movable block. A connecting component is provided between the speaker body and the mounting shell.

[0007] By adopting the above technical solution, during use, first, holes are drilled in the ceiling, and the mounting shell is inserted through the holes. Then, the support plate is swung horizontally so that its lower surface is against the upper surface of the ceiling. The mounting shell is placed on the ceiling, and then the speaker body is placed on the lower surface of the ceiling. The speaker body is connected to the mounting shell through the connecting components. During installation, the speaker body pulls down the mounting shell, compressing the spring and pressing the speaker body against the lower surface of the ceiling. At the same time, the support plate presses against the upper surface of the ceiling, thus fixing the speaker body and the mounting shell. During disassembly, the speaker body is removed, and the mounting shell can be disassembled. This method avoids the problem of cumbersome installation, which involves inserting the speaker shell into the hole, fixing it with screws, and then installing the speaker into the shell, which reduces installation efficiency.

[0008] Preferably, the connecting assembly includes a plurality of fixing bolts disposed below the speaker body, and a plurality of mounting blocks are fixedly connected to the side wall of the mounting housing, wherein the fixing bolts all penetrate the speaker body and are threadedly connected to the mounting blocks respectively.

[0009] By adopting the above technical solution, after placing the mounting shell on the upper surface of the ceiling, the fixing bolt is passed through the speaker body and threadedly connected to the mounting block. After the speaker body is in contact with the lower surface of the ceiling, the fixing bolt is rotated to move the mounting block downward and pull down the mounting shell. This facilitates the connection between the speaker body and the mounting shell while fixing the mounting shell to the ceiling.

[0010] Preferably, the mounting shell has multiple vertically arranged receiving grooves on its side wall, with the bottom of each receiving groove open, and both the fixed block and the movable block located within the receiving groove.

[0011] By adopting the above technical solution, the receiving groove prevents the fixed block and the moving block from extending outside the mounting shell, making it difficult to pass the mounting shell through the hole opened in the ceiling.

[0012] Preferably, the receiving groove has limit grooves on both sides of the sidewalls, and the moving block has limit blocks on both sides of the sidewalls, with the limit blocks slidably disposed in the limit grooves.

[0013] By adopting the above technical solution, the stability of the moving block can be improved by allowing the limiting block to slide in the limiting groove, thus preventing the moving block from detaching from the receiving groove.

[0014] Preferably, each spring is provided with a telescopic rod, and the two ends of the telescopic rod are fixedly connected to the fixed block and the movable block, respectively.

[0015] By adopting the above technical solution, the stability of the spring can be improved by using a telescopic rod, preventing the spring from bending when it contracts, which would cause damage to the spring.

[0016] Preferably, the lower surface of the support plate at the end away from the movable block is fixedly connected with a plug rod for insertion into the ceiling.

[0017] By adopting the above technical solution, when drilling holes in the ceiling, insert holes that match the plug rod are drilled around the holes. Then, the mounting shell is passed through the holes, and the support plate is swung so that the plug rod is inserted into the insert holes to pre-install the mounting shell. This prevents the mounting shell from rotating or lifting upwards when the fixing bolt is threaded into the mounting block after passing through the speaker body, which would make it difficult for the fixing bolt to be screwed into the mounting block.

[0018] Preferably, a mesh cover for protecting the speaker body is installed on the lower surface of the speaker body.

[0019] By adopting the above technical solution, the speaker body can be protected and hidden by installing the mesh cover on the lower surface of the speaker body, making the ceiling look cleaner and improving its aesthetics.

[0020] Preferably, the lower surface of each support plate is fixedly connected with a plurality of elastic rubber pads for reducing wear.

[0021] By adopting the above technical solution, the elastic rubber pad can prevent the support plate from directly contacting the ceiling, reduce the contact force on the ceiling, and prevent damage to the ceiling.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application utilizes a combination of fixed blocks, springs, and movable blocks. During use, holes are first drilled in the ceiling, and the mounting shell is inserted through these holes. Then, the support plate is swung horizontally, its lower surface adhering to the upper surface of the ceiling. The mounting shell is placed on the ceiling, and the speaker body is placed on the lower surface. The speaker body is then connected to the mounting shell via a connecting assembly. During installation, the speaker body pulls down the mounting shell, compressing the spring and pressing the speaker body against the lower surface of the ceiling. Simultaneously, the support plate presses against the upper surface of the ceiling, securing the speaker body and mounting shell. Disassembly involves removing the speaker body to remove the mounting shell. This method avoids the cumbersome process of inserting the speaker shell into holes, securing it with screws, and then installing the speaker into the shell, which reduces installation efficiency.

[0024] 2. When drilling holes in the ceiling, drill insertion holes around the holes that match the plug rods. Then, pass the mounting shell through the holes, swing the support plate, and insert the plug rods into the insertion holes to pre-install the mounting shell. This prevents the mounting shell from rotating or lifting upwards when the fixing bolts are threaded into the mounting block after passing through the speaker body, which would make it difficult for the fixing bolts to be screwed into the mounting block.

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a multi-point Bluetooth ceiling speaker.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A multi-point Bluetooth ceiling speaker includes a speaker body 1 and a mounting shell 2. The bottom of the speaker body 1 has a mirrored protrusion with an annular mounting part. The mounting shell 2 is provided with a fixing component, which includes a fixing block 3, a spring 4, a moving block 5 and a support plate 6.

[0033] Multiple fixed blocks 3 are provided, all fixedly connected to the upper part of the side wall of the mounting shell 2 and distributed in a ring array. Multiple springs 4 are provided, each fixedly connected to the lower surface of the fixed blocks 3. Multiple movable blocks 5 are provided, each fixedly connected to the end of the spring 4 away from the fixed blocks 3. Two fixed seats are fixedly connected to the lower surface of the movable blocks 5. Fixed rods are rotatably connected between the fixed seats (fixed seats and fixed rods are not shown in the figure). Multiple support plates 6 are provided, each sleeved on the fixed rod and hinged to the movable blocks 5. Connecting components are provided on the speaker body 1 and the mounting shell 2.

[0034] Reference Figure 1 and Figure 4 The connecting assembly includes multiple fixing bolts 7 located below the speaker body 1. Multiple mounting blocks 8 in a ring array are fixedly connected to the side wall of the mounting shell 2. The fixing bolts 7 all pass through the speaker body 1 and are threadedly connected to the mounting blocks 8 respectively. An L-shaped connecting pressure block 16 is also rotatably connected to the lower surface of the mounting block 8. Multiple connecting sleeves 17 are fixedly connected to the upper surface of the speaker body 1. A protrusion 18 for abutting the L-shaped connecting pressure block is provided at the bottom end of the side wall of the mounting shell 2. The fixing bolts 7 are located inside the connecting sleeves 17 respectively. After the mounting shell 2 is placed on the upper surface of the ceiling, the fixing bolts 7 are threadedly connected to the mounting blocks 8 by passing through the speaker body 1. After the speaker body 1 is in contact with the lower surface of the ceiling, the fixing bolts 7 are rotated to move the mounting blocks 8 downward and pull down the mounting shell 2, which facilitates the connection between the speaker body 1 and the mounting shell 2 while fixing the mounting shell 2 to the ceiling.

[0035] Reference Figure 1 The mounting shell 2 has multiple vertically arranged receiving grooves 9 on its side wall. The bottom of the receiving grooves 9 is open. The fixing block 3 and the moving block 5 are both located in the receiving grooves 9. The receiving grooves 9 prevent the fixing block 3 and the moving block 5 from extending outside the mounting shell 2, making it difficult to pass the mounting shell 2 through the hole opened in the ceiling.

[0036] Reference Figure 1 and Figure 3 Limiting grooves 10 are provided on both sides of the receiving groove 9, and limiting blocks 11 are provided on both sides of the moving block 5. The limiting blocks 11 are slidably disposed in the limiting grooves 10. By allowing the limiting blocks 11 to slide in the limiting grooves 10, the stability of the moving block 5 can be improved, and the moving block 5 can be prevented from leaving the receiving groove 9.

[0037] Reference Figure 1 and Figure 2 Each spring 4 is equipped with a telescopic rod 12. The two ends of the telescopic rod 12 are fixedly connected to the fixed block 3 and the moving block 5, respectively. The telescopic rod 12 can improve the stability of the spring 4 and prevent the spring 4 from bending when it contracts, which would cause the spring 4 to be damaged.

[0038] Reference Figure 1The lower surface of the support plate 6 away from the moving block 5 is fixedly connected with a plug rod 13 for inserting into the ceiling. When drilling holes in the ceiling, plug holes that match the plug rod 13 are drilled around the holes. Then, the mounting shell 2 is passed through the holes, and the support plate 6 is swung so that the plug rod 13 is inserted into the plug hole to pre-install the mounting shell 2. This prevents the mounting shell 2 from rotating or lifting upwards when the fixing bolt 7 is threaded into the mounting block 8 after passing through the speaker body 1. This would make it difficult for the fixing bolt 7 to be screwed into the mounting block 8.

[0039] Reference Figure 3 A mesh cover 14 for protecting the speaker body 1 is installed on the lower surface of the speaker body 1. The mesh cover 14 can be connected to the speaker body 1 by bolts or snap-fit. By installing the mesh cover 14 on the lower surface of the speaker body 1, the speaker body 1 can be protected and hidden, making the ceiling look cleaner and improving aesthetics.

[0040] Reference Figure 1 and Figure 4 Multiple elastic rubber pads 15 are fixedly connected to the lower surface of the support plate 6 to reduce wear. The elastic rubber pads 15 can prevent the support plate 6 from directly contacting the ceiling, reduce the contact force on the ceiling, and prevent damage to the ceiling.

[0041] The implementation principle of the multi-point Bluetooth ceiling speaker in this application embodiment is as follows: In use, first, holes are drilled in the ceiling, and simultaneously, insertion holes matching the connector rod 13 are drilled around the holes. Then, the mounting shell 2 is passed through the holes in the ceiling. By swinging the support plate 6, the support plate 6 is placed horizontally, so that the lower surface of the support plate 6 is attached to the upper surface of the ceiling. The connector rod 13 is inserted into the insertion holes, so that the mounting shell 2 is pre-installed on the ceiling. Then, the speaker body 1 is placed on the lower surface of the ceiling, so that the speaker body 1 is located in the hole. The annular mounting part on the speaker body 1 is attached to the lower surface of the ceiling. Depending on the thickness of the ceiling, there is a gap between the annular mounting part and the mounting shell. By passing the fixing bolt 7 through the annular mounting part on the speaker body 1, the fixing bolt 7... After the annular mounting part on the speaker body 1 is aligned with the lower surface of the ceiling, the fixing bolt 7 is rotated to move the mounting block 8 and the mounting shell 2 downwards. The bottom end of the mounting shell 2 is moved into the hole in the ceiling, and the speaker body 1 is installed inside the mounting shell 2. The spring 4 is compressed, and the speaker body 1 is pressed against the lower surface of the ceiling. At the same time, the support plate 6 is pressed against the upper surface of the ceiling. The speaker body 1 is connected to the mounting shell 2, and the mounting shell 2 is fixed to the ceiling. When disassembling, the speaker body 1 is removed, and the mounting shell 2 can be disassembled. This avoids the problem of the mounting shell 2 being inserted into the hole, fixed with screws, and then the speaker being installed into the mounting shell 2, which is more cumbersome and reduces the installation efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
