Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to an automatic anti-tipping smart speaker. Background Technology

[0002] With the increasing popularity of smart speakers, speakers with retractable displays are gradually becoming mainstream products. These speakers require the screen to be raised to a certain height (e.g., 1.2 meters) for easy operation. However, once the screen is raised, the backward force exerted by the user touching it causes the speaker's center of gravity to shift upward, significantly reducing stability. This risk of tipping over is further increased, especially in outdoor settings where the ground is uneven or contains gravel.

[0003] To address these issues, existing technologies typically employ manual supports around the speaker enclosure. However, this approach requires users to bend over and manually unfold and retract the supports after placing the speaker, a cumbersome process with a poor user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a solution to the problem of cumbersome operation of existing manual speaker stands.

[0005] To achieve the above objectives, this utility model proposes an automatic anti-tipping smart speaker, comprising:

[0006] The speaker body has a placement slot on its back.

[0007] An electrically retractable bracket is used to support the speaker body. The electrically retractable bracket includes a drive component and a support assembly. The drive component is disposed inside the speaker body, and the support assembly is accommodated in the placement slot. The drive end of the drive component is connected to the support assembly. The drive component is used to drive the support assembly to extend out of the speaker body or retract into the speaker body.

[0008] Optionally, the support assembly includes a housing and a telescopic member, wherein a sliding groove is provided inside the housing, and the telescopic member is movably disposed within the sliding groove.

[0009] Optionally, the support assembly further includes an adjustment assembly, one end of which is connected to the housing and the other end of which is connected to the telescopic member, so as to drive the telescopic member to extend or retract within the sliding groove.

[0010] Optionally, the adjusting assembly includes a screw and a bevel gear assembly, the bevel gear assembly including a driving bevel gear and a driven bevel gear, the driving bevel gear being fixed to the output shaft of the driving member, the driven bevel gear being fixed to one end of the screw near the driving member, and the driving bevel gear meshing with the driven bevel gear.

[0011] Optionally, the adjustment assembly further includes a connecting plate, which is fixed inside the telescopic member and threadedly connected to the screw. The connecting plate moves axially as the screw rotates to drive the telescopic member to extend or retract.

[0012] Optionally, the electric telescopic bracket further includes a contact portion, which is located at the end of the telescopic member away from the housing, and the side of the contact portion that abuts against the ground is provided with an inclined surface.

[0013] Optionally, the electric telescopic bracket further includes a pressure detector disposed on the contact portion, the pressure detector being used to detect the contact pressure between the contact portion and the ground, so as to control the opening and closing of the drive component.

[0014] Optionally, the smart speaker also includes a display screen, which is vertically mounted on the speaker body.

[0015] Optionally, the smart speaker further includes a control device for synchronously controlling the raising of the display screen and the extension of the electric telescopic bracket, or the lowering of the display screen and the retraction of the electric telescopic bracket.

[0016] Optionally, the placement slot is provided with a cover plate that covers the placement slot, and the size of the cover plate matches the placement slot.

[0017] The beneficial effects of this utility model are as follows: An electric telescopic bracket is set on the speaker body, and both the display screen and the electric telescopic bracket are electrically connected to the control device.

[0032] One embodiment of this utility model provides an automatic anti-tipping smart speaker, see reference. Figures 1 to 5 ,include:

[0033] Speaker body 1, with a placement groove 11 provided on the back of the speaker body 1;

[0034] An electric telescopic bracket 3 is used to support the speaker body 1. The electric telescopic bracket 3 includes a drive component 31 and a support component 32. The drive component 31 is disposed inside the speaker body 1, and the support component 32 is accommodated in the placement slot 11. The drive end of the drive component 31 is connected to the support component 32. The drive component 31 is used to drive the support component 32 to extend out of the speaker body 1 or retract into the speaker body 1.

[0035] This invention features an electrically operated telescopic bracket 3 on the speaker body 1. Both the display screen 2 and the electrically operated telescopic bracket 3 are electrically connected to a control device. The control device synchronously controls the raising and lowering of the display screen 2 and the extending and retracting of the electrically operated telescopic bracket 3. Specifically, when the display screen 2 is raised, the electrically operated telescopic bracket 3 extends synchronously from the placement slot 11 to support the speaker body 1; when the display screen 2 is lowered, the electrically operated telescopic bracket 3 retracts synchronously into the placement slot 11. This solves the problem of cumbersome operation of existing manual speaker brackets and improves the convenience of speaker use. In this embodiment, two electrically operated telescopic brackets 3 are used and are located on the back of the speaker body 1, providing users with convenient adjustment functionality. (Refer to...) Figure 2 The electric telescopic bracket 3 can also be configured as one, installed at the center of the back of the speaker body 1; further, in other embodiments, the electric telescopic bracket 3 can also be configured as three or more, spaced apart on the back of the speaker body 1. The specific number of electric telescopic brackets 3 is not limited here, and can be set according to the specific size of the smart speaker and the usage environment.

[0036] Furthermore, the support assembly 32 includes a housing 321 and a telescopic member 322. The housing 321 is fixedly disposed within the placement groove 11, and a sliding groove 3211 is provided within the housing 321. The telescopic member 322 is movably disposed within the sliding groove 3211. When the speaker body 1 requires support from the electrically telescopic bracket 3, the telescopic member 322 can extend out of the sliding groove 3211 to support the speaker body 1, thereby preventing the speaker from tipping over. When the speaker body 1 does not require additional support or needs to be carried, the telescopic member 322 can automatically retract into the sliding groove 3211, thus hiding inside the speaker body 1, maintaining the aesthetic appearance of the speaker body 1, and facilitating the transportation and carrying of the speaker.

[0037] Furthermore, the support assembly 32 also includes an adjustment assembly 33. One end of the adjustment assembly 33 is connected to the housing 321, and the other end is connected to the telescopic member 322, so as to drive the telescopic member 322 to extend or retract within the sliding groove 3211. Specifically, a fixing plate is provided in the sliding groove 3211, and a guide hole is provided on the fixing plate for the adjustment assembly 33 to pass through. The adjustment assembly 33 is fixedly installed in the housing 321 through the guide hole, so that the adjustment assembly 33 can maintain linear movement during the driving process, avoiding deviation or shaking, and improving the stability of the support assembly 32. One end of the adjustment assembly 33 is connected to the housing 321, and the other end is connected to the telescopic member 322. The adjustment assembly 33 is driven to move by the driving member 31 to drive the telescopic member 322 to extend or retract within the sliding groove 3211, so as to facilitate adjustment of the extension length of the telescopic member 322.

[0038] Furthermore, the adjusting assembly 33 also includes a connecting plate 34, which is fixed inside the telescopic member 322 and threadedly connected to the screw 331. The connecting plate 34 moves axially as the screw 331 rotates to drive the telescopic member 322 to extend or retract. Specifically, the connecting plate 34 is fixed inside the telescopic member 322, and a guide hole is provided on the connecting plate 34 for the screw 331 to pass through. The screw 331 passes through the guide hole via a bushing and is used to drive the telescopic member 322 to extend out of the sliding groove 3211 or retract into the sliding groove 3211 as the screw 331 rotates.

[0039] Furthermore, the adjusting component 33 includes a screw 331 and a bevel gear assembly 332. The bevel gear assembly 332 includes a driving bevel gear 3321 and a driven bevel gear 3322. The driving bevel gear 3321 is fixed to the output shaft of the driving member 31, and the driven bevel gear 3322 is fixed to one end of the screw 331 near the driving member 31. The driving bevel gear 3321 meshes with the driven bevel gear 3322. Specifically, the screw 331 passes through the guide hole and is fixedly installed in the housing 321 through the bushing. The drive member 31 is located on one side of the support assembly 32. The drive end of the drive member 31 is provided with a driving bevel gear 3321. The end of the screw 331 near the drive member 31 is fitted with a driven bevel gear 3322. The drive end of the drive member 31 passes through the housing 321 and meshes with the screw 331. When the drive member 31 is started, the driving bevel gear 3321 rotates accordingly. Since the driven bevel gear 3322 meshes with the driving bevel gear 3321, the screw 331 also rotates accordingly. Since the screw 331 is fixed in the housing 321 and connected to the telescopic member 322, when the screw 331 rotates, the rotational motion of the screw 331 is converted into linear motion, thereby pushing the telescopic member 322 out of the sliding groove 3211.

[0040] Furthermore, the electrically telescopic bracket 3 also includes a contact portion 323, which is located at the end of the telescopic member 322 away from the housing 321. The side of the contact portion 323 that abuts against the ground has an inclined surface, increasing the contact area between the bracket and the ground, thereby providing more stable support. Compared to traditional flat-bottomed supports, if the speaker is placed on uneven ground, traditional flat-bottomed supports may only have a few points of contact with the ground, easily causing the speaker to wobble and become unstable. However, by designing the contact portion 323 with an inclined surface structure in contact with the ground, the contact area can be increased, allowing the contact portion 323 to have more contact with the ground, thereby providing more stable support. It should be noted that in other embodiments, the contact portion 323 can be made of a material with elasticity and anti-slip properties, such as rubber or silicone, to further enhance the friction and adaptability with the ground. The part of the inclined surface that contacts the ground can also be designed with a textured or uneven structure to further enhance the contact area and friction with the ground. A protective cover can also be added to the contact portion 323 to prevent the contact portion 323 from being scratched with the ground and to extend the service life of the contact portion 323.

[0041] Furthermore, the electrically retractable bracket 3 also includes a pressure detector disposed on the contact portion 323. The pressure detector is used to detect the contact pressure between the contact portion 323 and the ground to control the opening and closing of the drive component 31. Specifically, when there are multiple electrically retractable brackets 3 on the speaker and the speaker is placed on uneven ground, the extension length required for each electrically retractable bracket 3 is different. By providing a pressure detector on the contact portion 323 of each electrically retractable bracket 3, the pressure detector can monitor the pressure change between the contact portion 323 and the ground in real time and feed it back to the control device. Based on the preset pressure threshold and the actual pressure value of each electrically retractable bracket 3, the control device will determine whether the drive component 31 needs to continue driving the retractable component 322 to extend or stop moving. When the pressure detector detects that the pressure value of the current contact part 323 is less than the predetermined pressure value, it sends a drive message to the control device to continue extending the electric telescopic bracket 3, thereby controlling the telescopic member 322 to continue extending. When the pressure detector detects that the pressure value of the current contact part 323 is greater than or equal to the predetermined pressure value, it sends a drive message to the control device to stop extending the electric telescopic bracket 3, thereby controlling the telescopic member 322 to stop extending, so as to realize the adaptive length adjustment of the electric telescopic bracket 3.

[0042] Furthermore, the smart speaker also includes a display screen 2, which is height-adjustable on the speaker body 1, making it convenient for users to use the speaker in different situations. When users watch movies using the smart speaker, they can raise the display screen 2 to a suitable height, at which time the display screen 2 presents users with delicate and vivid images. When users need to take the smart speaker out, they can lower the display screen 2 and store it inside the speaker body 1, making it convenient for users to carry and store.

[0043] Furthermore, the smart speaker also includes a control device, which is used to synchronously control the raising of the display screen 2 and the extension of the electric telescopic bracket 3, or the lowering of the display screen 2 and the retraction of the electric telescopic bracket 3. Specifically, the control device is electrically connected to the display screen 2 and the drive component 31. The control device controls the display screen 2 and the electric telescopic bracket 3 through built-in sensors or by receiving user commands. That is, when the display screen 2 is raised, the control device simultaneously controls the drive component 31 to drive the telescopic component 322 to extend out of the placement slot 11 to maintain the stability of the speaker and prevent the speaker from tipping over due to instability caused by the raising of the display screen 2. When the display screen 2 is lowered, the control device simultaneously controls the drive component 31 to drive the telescopic component 322 back into the placement slot 11. By synchronously controlling the raising and lowering of the display screen 2 and the extension and retraction of the electric telescopic bracket 3, the user does not need to bend over to manually unfold or retract the bracket, making it convenient for the user and improving the user experience.

[0044] Furthermore, a cover plate is provided on the placement slot 11 to cover the placement slot 11. The size of the cover plate matches the placement slot 11 to maintain the aesthetic appearance of the speaker body 1. When the electric telescopic bracket 3 is retracted into the placement slot 11, the cover plate is placed over the opening of the placement slot 11 to seal the electric telescopic bracket 3 in the placement slot 11, preventing external dust, moisture, and other impurities from entering the placement slot 11. The cover plate and the speaker body 1 are detachably connected, such as by snap-fit, hinge, or magnetic connection, facilitating user installation and removal. The color of the cover plate matches the color of the speaker body 1 to ensure the overall aesthetic appearance of the speaker body 1. When the cover plate and the speaker body 1 are magnetically connected, the telescopic component 322 can open the cover plate under the action of the driving component 31 when the user uses the electric telescopic bracket 3, simplifying the user's operation.

[0045] In some embodiments, the anti-tipping speaker is further provided with a storage structure for storing a microphone. The storage structure may be a cavity for accommodating and storing the microphone, with the microphone inserted into the cavity. The cavity depth is greater than or equal to the microphone length. The cavity includes an opening through which the microphone is inserted vertically or horizontally along its length direction into the cavity for storage. A microphone fixing structure may be provided inside or outside the opening to fix the microphone after storage. The opening may be located at any position in the speaker, including the top, side, and bottom surfaces of the speaker. Alternatively, the storage structure may be a groove into which the microphone is fitted and stored. A microphone fixing structure may be provided inside or outside the groove to fix the microphone after storage. The microphone is inserted vertically or horizontally along its length into the groove for storage. The groove may be located at any position in the speaker, including the top, side, and bottom surfaces of the speaker.

[0046] When a microphone is connected to a speaker, it will cause feedback if it is too close to the speaker. The harsh feedback sound emitted by the speaker will greatly affect the user experience. This is especially true when the microphone is stored in the speaker. The probability of feedback is even higher when the microphone hits or rubs against the speaker during storage. You can make the microphone automatically turn off to prevent feedback when the microphone is close to the speaker or when the microphone is stored in the speaker.

[0047] In some implementations, to prevent feedback when the microphone is near a smart speaker or when the microphone is housed in a smart speaker, the microphone can automatically shut down when it is near the smart speaker. Specifically, a sensing element can be placed on the microphone and / or the smart speaker. This sensing element detects the distance between the smart speaker and the microphone, and generates a corresponding sensing signal when the distance between the smart speaker and the microphone is less than or equal to a preset distance. This sensing signal is then sent to the microphone's control device, or the smart speaker sends the sensing signal to the microphone's control device, causing the control device to shut down the microphone. More specifically, the sensing element can be one or more, and can be a Hall element, a proximity sensor, an infrared sensor, or any other single electronic component capable of sensing the distance between the smart speaker and the microphone, or any combination of electronic components.

[0048] Specifically, the sensing elements are a Hall effect sensor and a magnetic component, which are respectively positioned in corresponding locations on the smart speaker and microphone. The microphone integrates charging functionality with the speaker via a plug-in or insert-in storage structure. In plug-in storage, the charging structure is located at the end of the speaker cavity furthest from the opening, and the microphone has power-receiving contacts at its bottom or end, automatically aligning with the charging interface after insertion. In insert-in storage, the charging structure can be positioned at one, the middle, or both ends of the recess, matching the microphone's power-receiving structure. During charging, the Hall effect sensor triggers the connection by sensing the change in magnetic field at the moment of power-on, ensuring stable charging startup. Furthermore, the speaker and microphone are physically fixed using magnetic components (such as magnets). The magnetic components are positioned outside the sensing range of the Hall effect sensor to avoid magnetic field interference during charging that could lead to misjudgments, while also improving the convenience and stability of storage.
