The present disclosure relates to a technical field of loudspeaker products, and particularly, to a loudspeaker and an electronic system using the loudspeaker.
Nowadays, with the development of electronic devices, loudspeakers have gradually entered everyone's home. However, some problems usually occur in use. For example, a screen or an operating panel on the loudspeaker is generally fixed, which makes it easy to affect the convenience of using the loudspeaker when it is not placed in position. Besides, sound produced by speakers in some loudspeakers also has relatively strong directivity, and thus, when the loudspeaker is not placed in place, it is easy to affect the playing effect of the loudspeaker.
A main purpose of the present disclosure is to provide a loudspeaker, which aims to provide a mechanical structure basis that the loudspeaker body is rotatable with respect to the base, such that when one sidewall of the loudspeaker body is provided with a screen or an operating panel, an orientation of the screen or the operating panel can be adjusted by rotating the loudspeaker body to improve the convenience for using the loudspeaker; or when a speaker facing the sidewall is provided on the loudspeaker body, an orientation of the speaker can be adjusted by rotating the loudspeaker body to ensure the playing effect of the loudspeaker.
To achieve the above purpose, the loudspeaker proposed by the present disclosure includes:
In an embodiment of the present disclosure, the first driver includes:

The present disclosure also proposes an electronic system including a loudspeaker, the loudspeaker includes:
According to the technical solution of the disclosure, during use of the loudspeaker, the first driver may drive the loudspeaker body to rotate with respect to the base, such that a sidewall of the loudspeaker body may be adjusted to face users in different directions. On the basis of this mechanical structure, when one sidewall of the loudspeaker body is provided with a screen or an operating panel, the first driver 30 may drive the loudspeaker body to rotate, such that the screen or the operating panel on the loudspeaker body face the position of the user, which is convenient for the user to watch the screen on the loudspeaker body or to operate the operating panel, thereby improving e the convenience for using the loudspeaker. When a speaker facing the sidewall is provided on the loudspeaker body, the first driver may drive the loudspeaker body to rotate so as to make the speaker on the loudspeaker body face the position of the user, which is convenient for the speaker on the loudspeaker body to produce and play sound toward the user better, thereby ensuring the playing effect of the loudspeaker.
Besides, as the loudspeaker body of the loudspeaker is rotatably disposed on the base, the first driver is located at a lower end of the loudspeaker. Thus, a center of gravity of the loudspeaker may be lowered, thereby improving the stability of the placement of the loudspeaker.

In an embodiment of the present disclosure, the base 10 may carry components such as the loudspeaker body 20 and the first driver 30, such that the components of the loudspeaker can be assembled as a whole. Meanwhile, when the loudspeaker is in normal use and is thus positioned on a supporting surface (for example, a table surface or a cabinet surface, etc.), a lower surface of the base 10 may be placed to abut against the supporting surface. Here, a projection of the base 10 on a horizontal plane may have a circular shape, such that its shape may be more regular and thus convenient to be machined. Of course, in other embodiments, the projection of the base 10 on the horizontal plane may also have a square shape, a triangular shape or other shape. The base 10 may be formed in a plate-like structure, such that the volume of the base 10 may be relatively smaller and thus facilitate reducing the overall volume of the loudspeaker. Of course, in other embodiments, the base 10 may also be a frame structure enclosed by a plurality of plates or a plurality of columns. In other words, the present disclosure does not limit the shape and formation of the base 10, as long as it can carry the components such as the loudspeaker body 20 and the first driver 30. The loudspeaker body 20 may play music or other voice information for the user to listen to. Here, a projection of the loudspeaker body 20 on the horizontal plane may have a circular shape, such that its shape may be more regular and thus convenient to be machined, and at the same time, its volume may be relatively smaller and thus facilitate reducing the overall volume of the loudspeaker. Of course, in other embodiments, the projection of the loudspeaker body 20 on the horizontal plane may also have a square shape, a triangular shape or other shape. In addition, the specific structure of the loudspeaker body 20 may be as follows: referring to
According to the technical solution of the disclosure, during use of the loudspeaker, the first driver 30 may drive the loudspeaker body 20 to rotate with respect to the base 10, such that one sidewall of the loudspeaker body 20 may be adjusted to face users in different directions. On the basis of this mechanical structure, when one sidewall of the loudspeaker body 20 is provided with a screen or an operating panel, the first driver 30 may drive the loudspeaker body 20 to rotate, such that the screen or the operating panel on the loudspeaker body 20 faces the position of the user, which is convenient for the user to watch the screen on the loudspeaker body 20 or to operate the operation panel, thereby improving the convenience to use the loudspeaker. When a speaker facing the sidewall is provided on the loudspeaker body 20, the first driver 30 may drive the loudspeaker body 20 to rotate, to make the speaker on the loudspeaker body 20 face the position of the user, which is convenient for the speaker on the loudspeaker body 20 to produce and play sound to the user better, thereby ensuring the playing effect of the loudspeaker.
Moreover, since the loudspeaker body 20 and the display screen 40 of the loudspeaker are rotatably disposed on the base 10 as a whole, the first driver 30 is located at a lower end of the loudspeaker. Thus, a center of gravity of the loudspeaker may be lowered, thereby improving the stability of the placement of the loudspeaker.
Referring to
It can be understood that when the base 10 is seated on the supporting surface, the base 10 may be limited and fixed with respect to the supporting surface under an action of the gravity of the loudspeaker. Thus, the driven gear 35 disposed on the base 10 is also limited and fixed. In this case, when the first motor 31 drives the driving gear 33 to rotate, the driving gear 33 may move along a circumferential direction of the driven gear 35 to make the loudspeaker body 20 to rotate with respect to the base 10. The first driver 30 includes the first motor 31, the driving gear 33 and the driven gear 35, such that the loudspeaker body 20 may be controlled to have a relatively suitable rotation speed, by adjusting a transmission ratio of the driving gear 33 to the driven gear 35. For example, since there is a deceleration effect when the transmission ratio of the gears is greater than 1, and the transmission ratio is equal to the inverse of the ratio of a diameter of the driving gear 33 to a diameter of the driven gear 35, the diameter of the driving gear 33 may be set less than the diameter of the driven gear 35. Thus, the rotation speed of the driven loudspeaker body 20 is reduced such that the rotation speed thereof is easy to control, which may avoid the loudspeaker body 20 from being driven to rotate too fast to cause the loudspeaker body 20 to accurately rotate to the position of the user. Meanwhile, such setting may also have the first motor 31 and the rotating parts of the base 10 and the loudspeaker body 20 disposed side by side in the horizontal direction. Thus, an overall height of the loudspeaker may be reduced and the position of the center of gravity may thus be lowered, thereby improving the stability of the placement of the loudspeaker on the supporting surface. Of course, it should be noted that the present disclosure is not limited thereto, and in other embodiments, the first motor 31 may also be disposed on the base 10. In this case, the driven gear 35 is inserted with the loudspeaker body 20, and the axis of the driven gear 35 coincides with the rotation axis 24 of the loudspeaker body 20. Alternatively, the first driver 30 may only include a first motor 31 which is disposed on the base 10. Thus, the loudspeaker body 20 is directly connected to an output shaft of the first motor 31 and is directly driven by the first motor 31.
Referring to
It can be understood that the installation tube 11 is protruded from the base 10, and an inner space of the installation tube 11 forms a rotating hole rotatably fitted with the rotating shaft 24, such that a thickness of the base 10 may be disposed relatively thin, thereby facilitating further reducing the overall volume of the base 10, and thus reducing the raw materials for required manufacture as well as manufacturing costs. Meanwhile, the driven gear 35 may also be directly fitted around the installation tube 11 on the outside. In this case, a volume of the installation tube 11 itself is relatively small, so that a volume of the driven gear 35 may also be disposed relatively small, thereby facilitating reducing the occupied space thereof to improve the convenience of installation of the driven gear 35 so as to reduce the overall volume of the loudspeaker. In other words, the disposition of the installation tube 11 on the base 10 functions to fix the loudspeaker body 20, and also functions to fix the driven gear 25. Thus, there is no need to separately provide, on the base 10, respective connection structures for fixing the loudspeaker body 20 and the driven gear. In this case, the structure of the base 10 is simplified, which facilitates improvement of the convenience of manufacture and reduction of the manufacturing cost. Here, the driven gear 35 and the installation tube 11 may be connected by interference fit, and of course, may also be connected by keys, snaps or screws. When the driven gear 35 is connected to the installation tube 11 by the screws, an upper end of the driven gear 35 may be extended towards the installation tube 11 to form a flange 351 abutting against an upper surface of the installation tube 11, so that it is more convenient to insert the screw into the installation tube 11 from top to bottom through the flange 351 and fasten it. Further, in order to improve stability and smoothness of the rotatable connection between the rotating shaft 24 and the installation tube 11, a bearing 241 may be inserted with the rotating shaft 24 by interference fit, the bearing 241 is rotatably fitted with the installation tube 11 to realize an indirect rotatable connection between the rotating shaft 24 and the installation tube 11. In order to improve the stability of the installation of the bearing 241, the bearing 241 may be accommodated in the installation tube 11, an upper surface of the flange 351 of the driven gear 35 is connected to a limiting ring 353, and a part of the limiting ring 353 abuts against an upper surface of the outer ring of the bearing 241. Thus, the bearing 241 is clamped and limited by cooperation of the limiting ring 353 and the installation tube 11 in the up and down direction. Here, screws may sequentially pass through the limiting ring 353 and the flange 351 on the driven gear 35 and be inserted into the installation tube 11, thereby achieving one-step fixation of the three components to improve the installation efficiency. Of course, it should be noted that the present disclosure is not limited thereto. In other embodiments, when the base 10 has a circular shape, the driven gear 35 may also be directly fitted around the base 10 at the outside, and in this case, the first motor 31 is also disposed on an outer circumferential surface of the loudspeaker body 20 correspondingly.
Referring to
It can be understood that the first installation space 25 provides an accommodation space for the first motor 31, through which the first installation space 25 may accommodate the first motor 31. Thus, the first motor 31 may be installed more compactly on the loudspeaker body 20, which facilitates further reduction of the overall volume of the loudspeaker. Meanwhile, the first motor 31 is provided in the loudspeaker body 20, and the first motor 31 may be isolated and protected by the first installation space 25. That is, it may facilitate hiding the first motor 31, which may reduce the possibility of the first motor 31 being damaged by foreign objects to facilitate extending the lifespan of the first motor 31, and at the same time, be also convenient to ensure the aesthetic appearance of the loudspeaker to improve the competitiveness of the product in the market. Moreover, when the first motor 31 is provided in the loudspeaker body 20, the thickness of the base 10 may also be reduced, such that the volume of the base 10 may also be provided relatively small. Here, referring to

It can be understood that the display screen 40 additionally disposed on the loudspeaker body 20 can make the loudspeaker body 20 have a relatively large display area, which is more convenient for the user to watch. Moreover, as the display screen 40 is disposed on the loudspeaker body 20, the first driver 30 may drive the loudspeaker body 20 to rotate and thus drive the display screen 40 to a view angle for better watching due to relatively facing the user's current position, when the user is in different positions. Here, the display screen 40 may be a screen with only display function. Of course, the display screen 40 may also be a touch screen, which is convenient for the user to directly perform a touch operation for, such as, playing on-demand songs, watching movies or doing online shopping, on the display screen 40. Further, the display screen 40 may also be provided with a microphone and a camera, which is convenient for the user to interact with the loudspeaker by the microphone using voice or capture and recognize the user's location by the camera to achieve an effect of tracking the user. In this case, the camera may be electrically connected to the first driver 30 and the second driver 50, and transmit the detected signal to the first driver 30 and the second driver 50 after recognition of the specific position of the user, such that the first driver 30 stops driving the loudspeaker body 20 in time and the second driver 50 stops driving the display screen 40 in time, thereby limiting the display screen 40 to be accurately located in a position relatively facing the user. In addition, the display screen 40 and the loudspeaker body 20 may be directly connected. Of course, they also may be indirectly connected by a connector. Further, the second driver 50 drives the display screen 40 to slide up and down with respect to the loudspeaker body 20, such that the position of the display screen 40 can also be adjusted in the up and down direction. That is, the diversification of the movement of the display screen 40 is improved, thereby more conveniently and accurately adjusting the display screen 40 to the user's current position to be adapted and thus making the user have a better view angle for watching.
Referring to
It can be understood that the rotating motion of the second motor 51 may be converted into a linear motion of the display screen 40 in the up and down direction by the transmission structure, such that the second driver 50 may not be expanded and contracted in the up and down direction. Thus, there is no need to dispose a sliding space for sliding the second driver 50 on the loudspeaker body 20, which facilitates further reduction of the overall volume of the loudspeaker. Of course, it should be noted that the present disclosure is not limited thereto, and in other embodiments, the second drive element 50 may also be just a cylinder or a linear module, etc.
Referring to
It can be understood that, as the belt 535 has elasticity, it can absorb the impact and the vibration such that the transmission structure 53 may have smooth transmission and reduced noise when driving the display screen 40 to slide in the up and down direction, thereby reducing noise interference and ensuring the playing effect when the loudspeaker plays music. Here, side circumferential surfaces of both the driving wheel 531 and the driven wheel 533 may be arc surfaces. Of course, side circumferential surfaces of both the driving wheel 531 and the driven wheel 533 may also be provided with convex teeth, and the belt 535 is provided with corresponding convex teeth engaged thereto, thus further improving the stability of driving of the driving wheel 531. In addition, it should be noted that the present disclosure is not limited thereto, and in other embodiments, the transmission structure may also include a lead screw and a slide seat. In this case, the lead screw is rotatably disposed on the loudspeaker body 20 and extended in the up and down direction, and one end of the lead screw is also connected to an output shaft of the second motor 51. The slide seat is inserted with the lead screw, and the display screen 40 is connected to the slide seat. Thus, the second drive motor may drive the lead screw to rotate, and the rotating lead screw drives the slide seat to move up and down to drive the display screen 40 to rotate.
Referring to
It can be understood that the second installation space 29 provides an accommodation space for the second driver 50, through which the second installation space 29 may accommodate the second driver 50. Thus, the second driver 50 may be installed more compactly on the loudspeaker body 20, which facilitates further reduction of the overall volume of the loudspeaker. Meanwhile, the second driver 50 may be isolated and protected by the second installation space 29 so as to reduce the possibility of the second driver 50 being damaged by foreign objects, which facilitate extending the lifespan of the second driver 50. Here, when the loudspeaker body 20 includes a box 27 and a cover 28, the loudspeaker body 20 and the cover 28 enclose to form the second space, such that the second space may be formed after the box 27 and the cover 28 are respectively formed and assembled, which reduces the complexity of forming the second space. Specifically, the second space may include an upper segment 291 and a lower segment 293, the upper segment 291 is located on the box 27, and the box 27 and the cover 28 enclose to form the lower segment 293, and the lower segment 293 communicate with the upper segment 291. In this case, the second motor 51 of the second driver 50 is located in the lower segment 293, parts of the driving wheel 531 and the belt 535 of the transmission structure are also located in the lower segment 293, and the other parts of the driven wheel 533 and the belt 535 may be located in the upper segment 291. Of course, in other embodiments, the second space may be opened only on the box 27 of the loudspeaker body 20. Alternatively, the second driver 50 is directly disposed on an outer circumferential surface of the box 27. In addition, the display screen 40 is connected to the belt 535 by the connecting rod 41 such that there is a certain distance between the display screen 40 and the loudspeaker body 20, which can reduce the possibility of interference during installation of the display screen 40 and the loudspeaker body 20 or during up-and-down slide of the display screen 40, which facilitates improvement of the safety of installation and the safety of movement of the display screen 40. Here, the connecting rod 41 may has a linear shape, may also have an arc shape, or may also have a dog-leg line shape, etc. Further, the belt 535 may be disposed with an installation block, and the connecting rod 41 may be detachably connected to the installation block disposed on the belt 535. Thus, when the display screen 40 is damaged, it may be removed from the belt 535 for maintenance and replacement, which improves the convenience of maintenance and replacement. Here, the connecting rod 41 and the installation block disposed on the belt 535 may be connected by screws or fasteners to simplify the assembly and disassembly process of the connecting rod 41 and the installation block.

It can be understood that the speaker 23 may be further surrounded by the inner casing 60 to effectively reduce the impact of vibration and resonance on the smart speaker 23, which facilitates improvement of sound producing performance of the loudspeaker for a relatively better sound. Meanwhile, a guide groove 65 may be disposed on the inner casing 60, such that a guide block 411 may be disposed on the connecting rod 41 correspondingly. The fit of the guide block 411 and the guide groove 65 may guide the display screen 40 to slide up and down, which facilitate improvement of the sliding stability of the display screen 40 to accurately slide to a preset position. Here, an outer circumferential surface of the box 27 of the loudspeaker body 20 may be concaved to form the guide groove 65. Or, off course, the outer circumferential surface of the box 27 may be provided with an L-shaped block, and the L-shaped block and the outer circumferential surface of the box 27 enclose to form the guide groove 65 so as to avoid the overall wall thickness of the box 27 from being set relatively thick, which facilitates reduction of the manufacturing costs.

It can be understood that the speaker 23 may be further surrounded by the upper casing 73 to effectively reduce the impact of vibration and resonance on the smart speaker 23, which facilitates improvement of sound producing performance of the loudspeaker for a relatively better sound. Meanwhile, such a setting also avoids the direct exposure of the speaker 23, which can reduce the possibility of damage caused by foreign objects, thus facilitating extending the lifespan of the speaker 23. The lower casing 71 is disposed to accommodate the base 10. In this case, the lower casing 71 abuts against and is supported by the supporting surface, and thus, a contact area between the loudspeaker and the supporting surface may be increased, which facilitates further improvement of the stability of the placement of the loudspeaker. Meanwhile, the projection area of the lower casing 71 on the horizontal plane may be set the same as the projection area of the upper casing 73 on the horizontal plane, so that the outermost circumferential surface of the loudspeaker has consistency and aesthetics are ensured, thereby improving the competitiveness of the product in the market. Here, the projections of the upper casing 73 and the lower casing 71 on the horizontal plane may both have circular shapes to make their volumes relatively small, and after the casing 70 is rotated with the inner casing 60 and the loudspeaker body 20, it is still consistent with the outer circumferential surface of the lower casing. In order to make the upper cavity 731 of the upper casing 73 and the lower cavity 711 of the lower casing 71 relatively small, the projections of the base 10, the inner casing 60 and the loudspeaker body 20 on the horizontal plane can all have circular shapes. In addition, in order to further improve the stability of the rotations of the loudspeaker body 20 and the inner casing 60, a lower section of the inner casing 60 may extend into between the base 10 and a sidewall of the lower cavity 711. Meanwhile, the inner casing 60 may also abut against a side circumferential surface of the base 10 and a bottom wall of the lower cavity 711, such that the side circumferential surface of the base 10 may function to guide the rotation, and the bottom wall of the lower cavity 711 may function to support.
