Description

Technical Field

[0001] This utility model relates to the field of ceiling-mounted speakers, specifically an adjustable ceiling-mounted speaker. Background Technology

[0002] A ceiling speaker is an audio system installed on the ceiling and is widely used in home theaters, conference rooms, or other public places. It features clear sound quality, high power, and a wide coverage area, broadcasting audio signals throughout the room. Ceiling speakers typically come equipped with a speaker to emit sound and are connected to a receiver or amplifier via cable or wirelessly.

[0003] Existing technology, disclosed in CN221930120U, provides a directional adjustable speaker assembly, including a mounting base, a movable end cap, a horn, and an elastic element. The mounting base has a bowl-shaped mounting cavity with a constricted opening to prevent internal components from detaching. The elastic element, horn, and movable end cap are sequentially inserted into the mounting cavity. One end of the movable end cap abuts against the horn, while the other end faces the opening of the mounting cavity. The circumferential surface of the movable end cap is an arc-shaped surface that conforms to the inner wall of the mounting cavity, allowing it to swing within the cavity. The speaker assembly provided by this invention allows the horn to move within the bowl-shaped mounting cavity, and its orientation can be adjusted within a small range by swinging. This allows the horn's orientation to be adjusted according to the user's needs or location, providing a better sound effect and experience.

[0004] The aforementioned patent mainly involves mounting the speaker movably within a bowl-shaped mounting cavity, allowing for small-range adjustment of its orientation by swinging. This enables the speaker to be adjusted according to the user's needs or location, providing a better sound effect and experience. However, the speaker in the aforementioned patent can only swing within a small range, which results in an extremely limited range of movement for the speaker inside the ceiling speaker, making it impossible to rotate and cover a larger area, thus reducing the practicality of the ceiling speaker. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable ceiling-mounted speaker, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable ceiling-mounted speaker, comprising a speaker housing with an inner groove. An adjustment device is movably mounted within the inner groove, and an adjustable speaker is movably mounted within the adjustment device. The speaker housing includes an electric actuator fixedly mounted on the top of the inner wall of the inner groove. The telescopic end of the electric actuator is fixedly mounted on the top of the outer wall of the adjustment device. The electric actuator is used to adjust the angle of the adjustment device left and right. The speaker housing also includes a limiting component fixed at the center of the bottom of the inner groove. The adjustment device is movably positioned directly above the limiting component. This positioning of the adjustment device directly above the limiting component limits the bottom of the device within the limiting component, while the top of the device can swing, allowing the device to swing along the limiting component, thus improving the accuracy of the adjustable ceiling-mounted speaker angle adjustment.

[0007] Furthermore, the adjustment device includes a housing, and a support component is fixedly installed at one end of the housing near the limiting component. The support component includes a semi-circular body fixedly installed at the bottom of the housing. The limiting component includes a fixed base plate fixedly installed at the bottom of the speaker housing. A first arc groove is fixedly installed on the top of the fixed base plate. An arc groove is formed at the end of the first arc groove away from the fixed base plate. The semi-circular body is movably located within the first arc groove.

[0008] Furthermore, the housing is a hollow housing with a circular groove at the top. The adjustable speaker passes through this groove and is located inside the housing. The bottom of the adjustable speaker is movably located at the bottom of the housing. An adjustment assembly and a spring post are fixedly installed on the top of the inner sidewall of the housing. The spring post is located below the adjustment assembly. The adjustment assembly is used to adjust the angle of the adjustable speaker forward and backward, and the spring post is used to reset the adjustable speaker. The spring post's reset function allows the adjustable speaker to be adjusted forward and backward using only the adjustment assembly and the spring post, improving the ease of operation of the adjustable ceiling-mounted speaker.

[0009] Furthermore, the adjustment assembly includes a frame fixedly mounted on the housing, within which a motor is fixedly mounted. A shaft is fixedly connected to the output end of the motor. The shaft has horizontal and vertical slots that are perpendicular to each other. A rope is disposed within the horizontal slot of the shaft, penetrating the adjustable speaker. A fixing body is fixedly mounted at the end of the rope away from the motor, and a bonding piece is fixedly mounted on the fixing body. The bonding piece is attached to the outer wall of the adjustable speaker. Because the bonding piece is attached to the outer wall of the adjustable speaker, when the bonding piece moves towards the adjustment assembly, it can move the adjustable speaker accordingly, improving the overall integrity of the internal structure of the adjustable ceiling-mounted speaker.

[0010] Furthermore, a locking bolt is movably installed in the vertical groove of the shaft, and the locking bolt is used to press and fix the bonding piece.

[0011] Furthermore, a block is fixedly installed at the bottom of the inner wall of the housing, and a second arc groove is fixedly installed at the top of the block. The top of the second arc groove has an arc groove. A semi-circular block is fixedly installed at the bottom of the adjustable speaker, and the adjustable speaker is limited to move within the second arc groove by the semi-circular block at the bottom.

[0012] Furthermore, a controller is fixedly installed at the bottom of the inner groove of the housing. The controller is electrically connected to the electric actuator and to the control box of the motor. This electrical connection allows the controller to control the internal structure of the adjustable ceiling-mounted speaker, enhancing the intelligence of its operation. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention places an adjustable speaker inside the speaker housing. The adjustable speaker can be adjusted to a wide range of angles (front, back, left, and right) by the operation of an electric actuator and a motor. Since the adjustable speaker itself can also be adjusted slightly, the adjustable ceiling speaker can be adjusted to a wider range during use, thus improving the practicality of the adjustable ceiling speaker.

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0017] Example The following is in conjunction with the appendix Figure 1 -Appendix Figure 4This application will be further described in detail below. An adjustable ceiling-mounted speaker includes a speaker housing 3, with an inner groove 2 inside the housing 3. An adjustment device 1 is movably mounted within the inner groove 2, and an adjustable speaker 4 is movably mounted within the adjustment device 1. The speaker housing 3 includes an electric actuator 31 fixedly mounted on the top of the inner wall of the inner groove 2. The telescopic end of the electric actuator 31 is fixedly mounted on the top of the outer wall of the adjustment device 1. The electric actuator 31 is used to adjust the angle of the adjustment device 1 left and right. The speaker housing 3 also includes a limiting component 32 fixedly located at the center of the bottom of the inner groove 2. The adjustment device 1 is movably located directly above the limiting component 32. The adjustment device 1 includes a housing 11, with an adjustable speaker 4 fixedly mounted at one end of the housing 11 near the limiting component 32. Support assembly 12 includes a semi-circular body 121 fixedly installed at the bottom of housing 11. Limiting assembly 32 includes a fixed base plate 321 fixedly installed at the bottom of speaker housing 3. A first arc groove 322 is fixedly installed on the top of the fixed base plate 321. An arc groove is formed at one end of the first arc groove 322 away from the fixed base plate 321. The semi-circular body 121 is movably located within the first arc groove 322. Housing 11 is a hollow housing. A circular groove is formed on the top of housing 11. Adjustable speaker 4 passes through the circular groove and is located within housing 11. The bottom of adjustable speaker 4 is movably located at the bottom of housing 11. Adjustment assembly 13 and spring column 14 are fixedly installed on the top of the inner side wall of housing 11. 4 is located below the adjustment assembly 13. The adjustment assembly 13 is used to adjust the angle of the adjustable speaker 4 forward and backward. The spring column 14 is used to move and reset the adjustable speaker 4. The adjustment assembly 13 includes a frame 131 fixedly installed on the housing 11. A motor 132 is fixedly installed in the frame 131. A shaft 134 is fixedly connected to the output end of the motor 132. A horizontal groove and a vertical groove are opened on the shaft 134. The horizontal groove and the vertical groove of the shaft 134 are perpendicular to each other. A rope 135 is arranged in the horizontal groove of the shaft 134. The rope 135 passes through the adjustable speaker 4. A fixing body 137 is fixedly installed at the end of the rope 135 away from the motor 132. A fitting piece 1 is fixedly installed on the fixing body 137. 36. The bonding piece 136 is bonded to the outer wall of the adjustable speaker 4. A locking bolt 133 is movably installed in the vertical groove of the shaft 134. The locking bolt 133 is used to press and fix the bonding piece 136. A block 122 is fixedly installed at the bottom of the inner wall of the housing 11. A second arc groove 123 is fixedly installed at the top of the block 122. An arc groove is opened at the top of the second arc groove 123. A semi-circular block is fixedly installed at the bottom of the adjustable speaker 4. The adjustable speaker 4 is limited to move within the second arc groove 123 by the semi-circular block at the bottom. A controller 15 is fixedly installed at the bottom of the inner groove of the housing 11. The controller 15 is electrically connected to the electric push rod 31 and the controller 15 is electrically connected to the control box of the motor 132.

[0018] The working principle of the controller 15 can be divided into four basic steps: input, processing, output, and feedback. First, the controller 15 receives input signals from external devices or users, such as button presses or sensor detection information. Next, the controller 15 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices. Since the electronic components inside the adjustable ceiling speaker are electrically connected to the controller 15, the controller 15 can directly control the electronic components inside the adjustable ceiling speaker. The controller 15 includes a microcontroller control board, a Bluetooth module, a power supply, and a remote control module. Therefore, users can remotely control the controller 15. Since the controller 15 is a mature existing technology, this utility model does not elaborate on it.

[0019] Since the tops of the first arc groove 322 and the second arc groove 123 are both provided with circular grooves, and the bottoms of the semicircular body 121 and the adjustable speaker 4 are both semicircular blocks, when the semicircular body 121 and the bottom semicircular blocks of the adjustable speaker 4 are located inside the first arc groove 322 and the second arc groove 123, the semicircular body 121 and the bottom semicircular blocks of the adjustable speaker 4 will be embedded inside the first arc groove 322 and the second arc groove 123. At this time, when the tops of the adjustable speaker 4 and the housing 11 are pushed by an external force, the bottoms of the adjustable speaker 4 and the housing 11 will not be located, but will rotate within the first arc groove 322 and the second arc groove 123, thereby causing the tops of the adjustable speaker 4 and the housing 11 to swing accordingly, and causing the speaker inside the adjustable speaker 4 to swing together, thus improving the practicality of the adjustable ceiling speaker.

[0020] Since the bonding piece 136 is attached to the adjustable speaker 4, when the motor 132 rotates, the rope 135 moves the bonding piece 136 toward the motor 132, thereby moving the top of the adjustable speaker 4 toward the motor 132. When the motor 132 rotates in the opposite direction, the spring force of the spring column 14 will cause the adjustable speaker 4 to return to its original position. The cooperation between the spring column 14 and the motor 132 allows the adjustable speaker 4 to be adjusted to a greater extent, improving the practicality of the adjustable ceiling speaker.

[0021] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the adjustable ceiling-mounted speaker are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figures. When using the adjustable ceiling-mounted speaker, if the user needs to adjust the adjustable speaker 4 at a small angle, only the speaker itself needs adjustment. If the user needs to adjust the adjustable speaker 4 at a larger angle, the user pulls the rope 135 by running the motor, causing a push-pull force on the top of the adjustable speaker 4, thus adjusting its angle. When the electric actuator 31 extends or retracts, it pushes the top of the housing 11, thereby adjusting the angle of the top of the adjustable speaker 4. The operation of the electric actuator and motor allows for a larger range of front-to-back and left-to-right angle adjustments. Because the adjustable speaker itself can be adjusted slightly, the adjustable ceiling-mounted speaker's adjustment range is wider, improving its practicality.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
