[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0039] First of all, those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can adjust it according to needs to adapt to specific application scenarios.

[0040] Secondly, it should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "inner" and "outer" are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0041] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0043] With the development of display device manufacturing technology, the integration level of display devices is getting higher and higher. The display screen of a display device usually integrates a sound system such as a speaker or a horn, so that the display screen can play sound while displaying images, in order to reduce the space occupied by the display device. In the prior art, the sound system of the display device is usually arranged at the bottom of the display screen, and the sound system is fixedly arranged relative to the display screen. And there are generally two common arrangement methods for the sound system at the bottom end of the display screen. The first is to embed the speaker of the sound system into the bottom frame of the display screen, making its sound-emitting surface face the front of the display screen. This method will cause the lower frame of the display screen to be wider, affecting the appearance of the product. The second is to install the speaker of the sound system on the back of the display screen, making its sound-emitting surface face downward of the display screen. Although this method can design the frame of the display screen to be narrower, the sound emitted propagates downward, with low efficiency.

[0044] Therefore, the auditory experience of the sound system in the prior art is poor. The whole sound system is placed at the bottom end of the display screen and is immovable relative to the display screen. Users need to adapt to the position of the sound system. In addition, there is a height difference between the sound system and the user's ears, and the sound is damaged during propagation, affecting the user's listening experience.

[0045] In view of the above problems, the embodiments of the present invention provide a display screen and a display device, which can improve the auditory experience of the sound system and make the sound system flexibly adapt to different application scenarios while ensuring a good appearance of the product.

[0046] Embodiment 1

[0047] Figure 1 It is the front view when the sound-emitting component of the display screen provided by the embodiment of the present application is retracted. Figure 2 It is the front view when the sound-emitting component of the display screen provided by the embodiment of the present application is deployed. Figure 3 It is the rear view when the sound-emitting component of the display screen provided by the embodiment of the present application is retracted. Figure 4 It is the exploded view of the sound-emitting unit in the display screen provided by the embodiment of the present application, as Figures 1 to 4As shown in the figure, this embodiment provides a display screen, which includes a display screen main body 10 and at least two sound generating units 20. The sound generating units 20 are installed on both sides of the display screen main body 10. The display screen main body 10 has a display side for displaying images, and the sound generating units 20 are used for emitting sounds.

[0048] Among them, the sound generating unit 20 includes a sound generating component and a first connection component. The first connection component includes a rotating shaft 22. The rotating shaft 22 can drive the sound generating component to move relative to the display screen main body 10, so that the sound generating component is retracted to the side of the display screen main body 10 facing away from the display surface, or exposed from both sides of the display screen main body 10. That is, in the retracted state, the sound generating component is located on the back of the display screen main body 10. In the unfolded state, the sound generating component extends from both sides of the display screen main body 10. Thus, it can be applied to different usage scenarios. When the user needs to use the display screen, the sound generating components on both sides of the display screen main body 10 will move outward relative to the display screen main body 10, so that the sound emitting surface of the sound generating component faces the user. When the display screen is not needed, the sound generating unit 20 can be retracted, and the sound generating component cannot be observed from the front of the display screen, thus ensuring the simplicity and beauty of the display screen.

[0049] Optionally, the sound generating component may include a speaker 23. The display screen of this embodiment may further include a second connection component. The second connection component is used to drive the speaker 23 to move along the extension direction of the side of the display screen main body 10. The speaker 23 is used for emitting sounds, and the second connection component can change the position where the speaker 23 emits sounds, so that the sound emitting direction of the display screen can be freely adjusted.

[0050] It should be noted that when the first connection component drives the sound generating component to move, it simultaneously drives the speaker 23 and the second connection component to move together. That is, the position of the speaker 23 relative to the display screen main body 10 is controlled by both the first connection component and the second connection component at the same time. The first connection component enables the speaker 23 to be unfolded or retracted from both sides of the display screen main body 10, and the second connection component enables the position of the speaker 23 along the length of the two side edges of the display screen main body 10 to be adjustable. Thus, the display screen can be applied to various scenarios during use, enabling the user to obtain a better auditory experience.

[0051] In addition, the movement of the first connection component driving the sound generating component can be either rotation or translation. That is, when the sound generating component is retracted and unfolded, it can be either a flipping motion or a horizontal translation relative to the display screen main body 10. Hereinafter, the motion mode and the specific structure of the corresponding first connection component will be described in detail by taking the flipping motion as an example.

[0052] When the sound-emitting component is flipped relative to the display screen body 10 under the drive of the first connecting component, so as to be folded or unfolded, as an optional embodiment, the first connecting component may include a first driving unit 21, the first driving unit 21 is connected to the rotating shaft 22, the first driving unit 21 is installed on the side of the display screen body 10 away from the display surface, and the sound-emitting component is connected to the rotating shaft 22 so as to move relative to the display screen body 10 under the drive of the rotating shaft 22.

[0053] Specifically, the rotating shaft 22 connected to the first driving unit 21 is the flip driving shaft of the sound-emitting component. The first driving unit 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 and the sound-emitting component are relatively fixed, so that the sound-emitting component is driven to rotate synchronously. The expansion and contraction of the sound-emitting component is the reciprocating rotation around the rotating shaft 22.

[0054] When the sound-emitting component rotates to the side of the display screen body 10 away from the display surface, the speaker 23 is located within the coverage range of the edge of the display screen body 10 ; when the sound-emitting component extends from the side of the display screen body 10 , the speaker 23 is exposed from the edge of the display screen body 10 .

[0055] Optionally, when the sound-emitting component is unfolded, the direction of its sound-emitting surface is consistent with the direction of the display side of the display screen body 10, and when the sound-emitting component is folded, the surface on the side away from the sound-emitting surface can be attached to the back of the display screen body 10. The rotation angle of the sound-emitting component from the folded state to the unfolded state or from the unfolded state to the folded state relative to the display screen body 10 can be 90° to 180°. It is only necessary to expose the sound-emitting surface of the sound-emitting component or hide the sound-emitting component as a whole on the back of the display screen body 10. By way of example, the rotation angle of the sound-emitting component for unfolding and folding can be 90°, 120°, 150°, or 180°, and the embodiments of the present application do not specifically limit this.

[0056] Furthermore, a receiving groove may be provided at the back edge of the display screen body 10, i.e., the position where the sound unit 20 is installed on the side away from the display side. When the sound component is folded, it may be at least partially accommodated in the receiving groove, thereby making the overall structure of the display screen more compact.

[0057] It should be noted that sound units 20 are installed on both sides of the display screen body 10. The sound units 20 on both sides have the same structure and working mode, and the sound units 20 on both sides correspond to the positions of the user's ears, so that a better auditory experience can be obtained. The sound units 20 on both sides can be expanded and folded synchronously, or the positions can be adjusted separately. This implementation does not make specific limitations on this.

[0058] The first driving unit 21 serves as the power source for the flipping of the sound - producing component. It is fixedly installed on the back of the display screen main body 10. Hereinafter, the structure of the first driving unit 21 and the way of driving the rotating shaft 22 will be described in detail.

[0059] As an alternative embodiment, the first driving unit 21 may include a motor box 212 and at least one motor 211. The motor 211 is installed inside the motor box 212. The output end of the first driving unit 21 is the output shaft of the motor 211, and the rotating shaft 22 is coaxially connected to the output shaft of the motor 211.

[0060] Optionally, there may be two first driving units 21. The two first driving units 21 may be respectively arranged at both ends of the rotating shaft 22. That is, there are two motors 211 driving the rotation of the rotating shaft 22. The two motors 211 can synchronously drive the rotating shaft 22 to rotate, so that the folding of the sound - producing component has better stability and reliability.

[0061] Optionally, the extending direction of the rotating shaft 22 is the same as the length direction of the side of the display screen main body 10. The two driving units are arranged at both ends of the rotating shaft 22 along the length direction of the side of the display screen main body 10. The two ends of the rotating shaft 22 and the output shaft of the motor 211 can be connected through a coupling.

[0062] In addition, the motor 211 can be a servo motor or a small stepping motor. Specific parameters such as the power and output torque of the motor 211 can be selected according to the size and weight of the sound - producing component it needs to drive. The shaft diameter of the rotating shaft 22 can match the size of the output shaft of the motor 211, and the length of the rotating shaft 22 can be selected according to the length of the sound - producing component it is installed on. This embodiment does not make specific limitations on these.

[0063] In some other embodiments, the folding and unfolding of the sound - producing component can also be a horizontal movement relative to the display screen main body 10 driven by the first connecting component. The moving direction of the sound - producing component can be perpendicular to the side of the display screen main body 10.

[0064] Specifically, the first connecting component can adopt a structure of driving a lead - screw nut to move linearly by a motor, that is, the motor drives the lead - screw to rotate. The lead - screw nut is in threaded cooperation with the lead - screw and moves along the axial direction of the lead - screw as the lead - screw rotates. Thus, by the forward and reverse rotation of the motor, the lead - screw nut can move horizontally along the axial direction of the lead - screw, and correspondingly, the sound - producing component can be extended and retracted on the side of the display screen main body 10.

[0065] It should be noted that the way the first connection component drives the sound - generating component to move only differs in the movement process of the sound - generating component unfolding and retracting from the back of the display main body 10. Whether the sound - generating component uses a flipping motion or a horizontal movement method, it can have the same structure and sound - generating method. The structure of the sound - generating component will be specifically and detailedly described below.

[0066] As an optional implementation manner, the second connection component may include a housing 24 and a slide - rail mechanism 25. The housing 24 has a receiving cavity. Both the slide - rail mechanism 25 and the speaker 23 are arranged in the receiving cavity. The slide - rail mechanism 25 includes a slide rail 251 and a slider 252. The slide rail 251 extends along the length direction of the side of the display main body 10, and the speaker 23 is fixedly connected to the slider 252 to move along the length direction of the slide rail 251.

[0067] Optionally, there may be two sliders 252, and the two are spaced along the length direction of the slide rail 251. The two sliders 252 can be respectively connected to both ends of the speaker 23 through fasteners, or the speaker 23 can be directly connected to the slider 252 by gluing. When the second connection component drives the speaker 23 to move along the length direction of the slide rail 251, a driving force can be applied to the slider 252, or a driving force can be directly applied to the speaker 23. The slider 252 can improve the smoothness of the movement of the speaker 23, and at the same time, the method of multiple sliders 252 can ensure the reliability and stability of the installation and movement process of the speaker 23.

[0068] Optionally, the length of the housing 24 can match the length of the rotating shaft 22. The outer side wall of the housing 24 is fixedly connected to the rotating shaft 22 to flip relative to the display main body 10 under the drive of the rotating shaft 22, that is, the sound - generating component as a whole is driven by the rotating shaft 22 to flip, and the slide - rail mechanism 25, the speaker 23 and the second connection component are all installed inside the housing 24.

[0069] Furthermore, the outer shape of the housing 24 can be a regular shape such as a cuboid, a cylinder or a sector - shaped cylinder, etc. This embodiment does not make specific limitations on this. A slot extending along its length direction can be provided on the outer side wall of the housing 24, and at least part of the shaft section of the rotating shaft 22 can be clamped in the slot.

[0070] Exemplarily, the rotating shaft 22 can be tightened against the slot wall of the slot by interference fit to realize the fixed installation of the rotating shaft 22 and the housing 24, and drive the housing 24 to rotate synchronously when the rotating shaft 22 rotates, or the rotating shaft 22 can be connected to the housing 24 through fasteners such as screws. This embodiment does not make specific limitations on the specific fixing method of the rotating shaft 22 and the housing 24.

[0071] It should be noted that the length of the outer shell 24 is less than or equal to the length of the side of the display screen main body 10. The shape of the accommodating cavity of the outer shell 24 is consistent with the outer shape of the outer shell 24, that is, the accommodating cavity also extends along the length direction of the side of the display screen main body 10. Thus, the slide rail 251 can extend from one end of the accommodating cavity to the other end, and the stroke of the slider 252 moving in the length direction of the slide rail 251 is the stroke of the speaker 23 moving along the length direction of the side of the display screen main body 10. Such a setting can enable the speaker 23 to have a larger movement range when moving up and down along the side of the display screen main body 10. Therefore, when adjusting the height of the speaker 23 to select the sound-emitting position according to different usage scenarios, there is a larger adjustment space.

[0072] The adjustment of the height position of the speaker 23 can be achieved through the second connection component. The structure of the second connection component and the way it drives the movement of the speaker 23 will be described in detail below.

[0073] As an alternative, the second connection component may further include a second driving unit. At least one of the speaker 23 and the slider 252 is connected to the output end of the second driving unit. Thus, the second driving unit can drive the speaker 23 to reciprocate along the length direction of the slide rail 251 to adjust the sound-emitting position of the speaker 23.

[0074] Exemplarily, the second driving unit can be a linear motor. The output end of the linear motor can be fixedly connected to the slider 252, and the stroke direction of the output end of the linear motor is consistent with the length direction of the slide rail 251.

[0075] In addition, the second driving unit can also adopt a rotary motor, and the second connection component may further include a transmission unit. The transmission unit can convert the rotary motion output by the second driving unit into a linear motion through a lead screw drive or a synchronous belt drive, etc., so as to drive the slider 252 to move, and correspondingly realize the adjustment of the up and down position of the speaker 23.

[0076] It should be noted that the second connection component can be arranged on the side or the end of the slide rail mechanism 25. The structures and working principles of the above-mentioned linear motor, as well as the transmission methods such as the lead screw and the synchronous belt, are all prior arts and will not be elaborated here. In this embodiment, the specific way of the second connection component driving the speaker 23 to linearly move along the length direction of the side of the display screen main body 10 is not limited.

[0077] As an alternative implementation, the sound-emitting surface of the outer shell 24 can be provided with a mesh structure 241. When the sound-emitting component extends from both sides of the display screen main body 10, the sound-emitting surface faces the same direction as the display surface of the display screen main body 10, so that the sound emitted by the speaker 23 can pass through the outer shell 24 and has a better propagation effect.

[0078] Finally, it should be noted that a plurality of sound units 20 can be symmetrically arranged on each side of the display screen body 10, that is, two or more sound units 20 can be provided on a single side of the display screen body 10, and the multiple sound units 20 on each side can be arranged at intervals along the length direction of the side of the display screen body 10, and can be synchronously retracted or expanded, so that the display screen has a better sound effect.

[0079] The present embodiment provides a display screen, which includes a display screen body and at least two sound units, the sound units are installed on both sides of the display screen body, the sound units include a sound component and a first connecting component, the first connecting component is used to drive the sound component to move relative to the display screen body, so that the sound component is retracted to the side of the display screen body away from the display surface, or extends from both sides of the display screen body; the sound component includes a speaker, and the speaker can move along the extension direction of the side of the display screen body, so that the sound position of the display screen can be freely adjusted, thereby improving the auditory experience of the sound unit.
