[0025] like Figure 1 , Figure 2 and Figure 3 As shown in one embodiment of this utility model application, a smart speaker module with a height-adjustable speaker column is disclosed, comprising a main body 10, a speaker column body 20, and a drive structure 30. The main body 10 is provided with a storage groove 11; an assembly cavity 12 is formed on the side wall of the storage groove 11; the speaker column body 20 is height-adjustably disposed in the storage groove 11; a transmission rack 21 is axially disposed on the outer surface of the speaker column body 20; the drive structure 30 is connected to the main body 10 and installed in the assembly cavity 12; the output shaft of the drive structure 30 extends into the storage groove 11; and a transmission gear 31 is disposed on the output shaft of the drive structure 30, the transmission gear 31 meshing with the transmission rack 21.

[0026] The smart speaker module disclosed in this embodiment can be used in audio equipment. The main body 10 can be set in a cubic shape, consisting of a shell and circuit boards, switches, etc. inside the shell. The main body 10 can be electrically connected to the main control board of the audio equipment through wires 50 to automatically control the drive structure 30 and the speaker 22 in the speaker column body 20. In addition, a screen, tablet computer, etc. can be set on the main body 10 to increase the interactivity of the smart speaker module and improve the intelligence level of the product. The shell of the main body 10 can be equipped with a telescopic handle, casters, etc. to increase the flexibility of the main body 10 and facilitate movement and transportation.

[0027] Specifically, a sound column is a column containing a sound-generating device. In this embodiment, the sound column body 20 can be equipped with multiple loudspeakers 22, such as... Figure 3 As shown, the positions of multiple speakers 22 can be flexibly designed according to the sound field requirements, such as being spaced apart along the axial direction of the sound column, or arranged in a zigzag shape.

[0028] The drive structure 30 disclosed in this embodiment is set in the assembly cavity 12, making reasonable use of the space in the main body 10. It can avoid the sound column body 20. Only the output end of the drive structure 30 extends into the storage groove 11 to assemble the transmission gear 31 and achieve the transmission effect with the transmission rack 21.

[0029] When the smart speaker module is working, the drive structure 30 drives the transmission gear 31 to rotate, thereby applying a thrust to the transmission rack 21, so that the speaker column body 20 can extend beyond the storage slot 11 and maintain a certain height. The speaker 22 inside the speaker column body 20 can transmit sound in a specific direction, especially for outdoor parks, campuses, squares and other open places, to achieve the effect of expanding the sound field.

[0030] In addition, when engaged, the transmission gear 31 and the transmission rack 21 are in close contact, which helps to improve the stability of the support and reduce the chance of the sound column body 20 shaking or sliding down.

[0031] When it is not necessary to expand the sound field, the drive structure 30 drives the transmission gear 31 to rotate in the opposite direction, causing the transmission rack 21 to descend, thereby retracting the sound column body 20 into the storage groove 11 to reduce collisions and facilitate transportation or storage.

[0032] It should be noted that the drive structure 30 and the sound column body 20 disclosed in this embodiment achieve the transmission effect through the meshing of the transmission gear 31 and the transmission rack 21. However, the protection scope of this utility model is not limited to this. Other types of transmission methods can achieve the technical effect of driving the sound column body 20 to rise and fall in the storage slot 11. As equivalent replacements for the concept of this utility model, they should also be within the protection scope of this application.

[0033] In summary, the smart speaker module disclosed in this embodiment, by arbitrarily mounting the speaker column body 20 on the main body 10, can balance the effect of expanding the sound field and the convenience of product maintenance, making it easy to use.

[0034] Specifically, as another embodiment of this application, two transmission racks 21 are disclosed, which are symmetrically arranged on both sides of the sound column body 20; two assembly cavities 12 are disclosed, which are symmetrically arranged on both sides of the receiving groove 11; and two drive structures 30 are disclosed, which are respectively installed in the two assembly cavities 12 to drive the two transmission racks 21 respectively.

[0035] In this embodiment, by symmetrically arranging two drive structures 30, two transmission gears 31, and two transmission racks 21, the two sides of the sound column body 20 are simultaneously subjected to thrust of the same direction and magnitude. This allows for smooth lifting and lowering, preventing lateral tilting and jamming, and reducing friction between the sound column body 20 and the side wall of the storage slot 11. Simultaneously, when the sound column body 20 is raised, the transmission gears 31 on both sides provide support, sharing the weight of the sound column body 20 and reducing the likelihood of wear and deformation of the transmission gears 31, further improving the stability of the sound column body 20 during use.

[0036] Specifically, in another embodiment of this invention, the two transmission racks 21 are symmetrically arranged about the central axis of the sound column body 20. When the transmission gear 31 exerts a thrust on the transmission racks 21, the direction of the thrust is in the same vertical plane as the center of gravity of the sound column body 20, so as to maintain balance.

[0037] Specifically, as another embodiment of this application, a groove is provided on the outer side wall of the sound column body 20, the groove being used to accommodate the transmission rack 21; the transmission rack 21 is welded or bonded to the sound column body 20.

[0038] The sound column body 20 disclosed in this embodiment can be made of plastic or metal. A groove is formed on the outer surface of the sound column body 20 by sheet metal forming or compression molding. The transmission rack 21 is placed within the groove, reducing contact between the transmission rack 21 and the sidewall of the receiving groove 11. This improves the smoothness of the outer wall of the sound column body 20, facilitating smooth movement within the receiving groove 11 and reducing friction. In another embodiment of this invention, to reduce friction, a clearance groove can be provided on the receiving groove 11 at a position opposite to the transmission rack 21. The transmission gear 31 is placed in the clearance groove, allowing the transmission rack 21 to move up and down within the clearance groove.

[0039] From another perspective, the groove disclosed in this embodiment can limit the transmission rack 21, improve the stability of the connection between the transmission rack 21 and the sound column body 20, and when the transmission gear 31 generates thrust, it can keep the transmission rack 21 and the sound column body 20 rising and falling at the same time, thereby improving the control accuracy of the audio module.

[0040] Specifically, the transmission rack 21 disclosed in this embodiment can be made of metal and connected to the sound column body 20 by welding, or it can be made of plastic to reduce weight. An adhesive layer can also be applied into the groove to bond the transmission rack 21, using bonding instead of welding to simplify the assembly process and improve processing efficiency.

[0041] It should be noted that this embodiment only illustrates that the transmission rack 21 is fixed by bonding or welding, but the scope of protection of this utility model is not limited to this. Other types of fixing methods, such as screwing or integral molding, as long as they can achieve the technical effect disclosed in this application, can be regarded as equivalent replacements of the concept of this utility model and should also be within the scope of protection of this application.

[0042] like Figure 1 and Figure 2 As shown, in another embodiment of this application, the cross-sectional shape of the speaker column body 20 is the same as the cross-sectional shape of the receiving groove 11. In this embodiment, the speaker column body 20 is inserted into the receiving groove 11 and is in close contact with the side wall of the receiving groove 11. Therefore, the contact gap in the receiving groove 11 is small, which can reduce the possibility of dust or impurities falling in and avoid affecting the raising and lowering of the speaker column body 20. Moreover, the high-precision assembly between the speaker column body 20 and the main body 10 can improve the stability of the structure. During transportation, the speaker column body 20 is completely contained in the receiving groove 11, with less collision between it and the main body 10, which can reduce the probability of accidental damage.

[0043] Specifically, as another embodiment of this application, the drive structure 30 is disclosed to include any one of a DC motor, a servo motor, and a stepper motor. The speaker column body 10 disclosed in this embodiment needs to move up and down within the storage slot 11; therefore, a DC motor with fast response speed can be used, or a servo motor or stepper motor with high control precision can be used to improve the control precision of the smart speaker module.

[0044] like Figure 3 As shown, in another embodiment of this application, a plurality of speakers 22 are provided on the speaker column body 20, and a main board 23 connected to the speakers 22 is disclosed; the smart speaker module includes a telescopic rod 40 and a wire 50, the telescopic rod 40 is disposed at the bottom of the storage slot 11; the top of the telescopic rod 40 is connected to the speaker column body 20; the wire 50 is spirally wound on the telescopic rod 40; the end of the wire 50 extends into the speaker column body 20 for connecting to the main board 23.

[0045] In this embodiment, the speaker column body 20 is equipped with a speaker 22 and a main board 23. A telescopic rod 40 is installed within the storage slot 11, allowing the wire 50 to extend spirally along the extension direction of the telescopic rod 40 into the speaker column body 20 and connect electrically with the main board 23. When the speaker column body 20 rises, the telescopic rod 40 is extended, and the wire 50 is pulled upwards. The wire 50 maintains its connection with the main board 23, supplying power to the speaker 22, enabling continuous and stable sound output. When the speaker column body 20 retracts into the storage slot 11, the telescopic rod 40 shortens, and the wire 50 is neatly wound around the telescopic rod 40. This reduces the likelihood of the wire 50 tangling, allowing the speaker column body 20 to be raised and lowered multiple times for repeated use, while maintaining circuit safety and extending the lifespan of the sound module.

[0046] like Figure 4 and Figure 5 As shown, in another embodiment of this application, a through hole 13 is provided on the side wall of the storage slot 11; the smart speaker module includes a sensor 60, which is disposed in the through hole 13. The speaker column body 20 disclosed in this embodiment is columnar. During the raising process, the center of gravity of the speaker column body 20 rises, and the stability decreases, so the raising height needs to be limited during use.

[0047] In this embodiment, the drive structure 30 drives the sound column body 20 to move. The sensor 60 senses the position of the sound column body 20, thereby monitoring its rising height. When the factory-set rising height is reached, the drive structure 30 is promptly shut off to prevent the sound column body 20 from rising excessively. In another embodiment, limiting blocks can be provided at both ends of the transmission rack 21 to abut against the transmission gear 31, limiting the transmission gear 31 to prevent it from disengaging from the transmission rack 21 and increasing structural stability.

[0048] Specifically, in this embodiment, the position of the sensor 60 is fixed. The rising height of the speaker column body 20 can be determined by measuring the movement path or detecting the target point. For example, the through hole 13 is set near the opening of the storage slot 11. The speaker column body 20 blocks the through hole 13 during its ascent. When it reaches the limit height, the speaker column body 20 moves above the through hole 13. At this time, the sensor 60 can detect that the obstruction in front is gone, and it can determine that the speaker column body 20 has risen to the correct position. The drive structure 30 should be shut down immediately. Another example is that strips of different colors (e.g., red at the top and black at the bottom) can be set on the speaker column body 20. The sensor 60 sends a detection signal (e.g., a light signal) to the strip. In the initial state, the color detected directly in front of the sensor 60 is red. When the speaker column body 20 rises to its highest height, the color detected by the sensor 60 is black. At this time, the drive structure 30 should be shut down immediately.

[0049] In summary, by setting up sensor 60 to detect the height of the sound column body 20 in real time, the safety of the sound column body 20 during use can be guaranteed.

[0050] Specifically, the sensor 60 disclosed in this embodiment includes, but is not limited to, any one of a laser sensor, an ultrasonic sensor, and an infrared sensor. The sensor 60 disclosed in this embodiment can be selected in various ways according to production needs. Laser sensors have advantages such as high speed, high accuracy, and strong anti-interference ability; ultrasonic sensors have the advantage of good directionality; and infrared sensors have the advantage of high sensitivity.

[0051] It should be noted that this embodiment is only an example of the type of sensor 60, but the protection scope of this utility model is not limited to this. Other types of sensors 60, as long as they can achieve the technical effects disclosed in this application, can be used as equivalent replacements for the concept of this utility model and should also be within the protection scope of this application.

[0052] Specifically, as another embodiment of this application, multiple through holes 13 are disclosed, and the multiple through holes 13 are spaced apart along the depth direction of the receiving groove 11; and multiple sensors 60 are provided. In this embodiment, by providing multiple sensors 60, the real-time position monitoring accuracy of the speaker column body 20 can be further improved, and the safety of using the smart speaker module can be further guaranteed.

[0053] Specifically, as another embodiment of this application, a contact sensor is provided on the outer wall of the sound column body 20. Two contact sensors are provided, and the two contact sensors are respectively located at both ends of the transmission rack 21.

[0054] During the lifting and lowering process, the transmission gear 31 and the transmission rack 21 move relative to each other. When the transmission gear 31 touches the contact sensor, the control drive structure 30 is closed, which can prevent the transmission gear 31 from disengaging from the transmission rack 21. This achieves the purpose of controlling the height or height of the speaker column body 20, so that the speaker column body 20 will not fall out of the storage slot 11 due to being raised, nor will it hit the bottom of the storage slot 11 due to continuous descent, further ensuring the safety of the smart speaker module.

[0055] Specifically, as another embodiment of this application, a smart speaker is also disclosed, which includes a smart speaker module with a height-adjustable sound column as described in any of the above.

[0056] In summary, this application discloses a smart speaker module with a height-adjustable speaker column, including a main body 10, a speaker column body 20, and a drive structure 30. The main body 10 has a storage slot 11; an assembly cavity 12 is formed on the side wall of the storage slot 11; the speaker column body 20 is height-adjustably disposed within the storage slot 11; a transmission rack 21 is axially disposed on the outer surface of the speaker column body 20; the drive structure 30 is connected to the main body 10 and installed within the assembly cavity 12; the output shaft of the drive structure 30 extends into the storage slot 11; and a transmission gear 31 is disposed on the output shaft of the drive structure 30, the transmission gear 31 meshing with the transmission rack 21. The smart speaker module disclosed in this embodiment, by height-adjustably disposing of the speaker column body 20 on the main body 10, can balance the effect of expanding the sound field with ease of maintenance, making it convenient to use.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0058] It should be noted that this utility model uses a smart speaker module with a height-adjustable sound column and a smart speaker as examples to introduce the specific structure and working principle of this utility model. However, the application of this utility model is not limited to smart speaker modules with a height-adjustable sound column and smart speakers. It can also be applied to the detection, production and use of other similar workpieces.

[0059] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
