[0026] As consumers increasingly value home aesthetics, they are more inclined to choose display devices that blend seamlessly into their home environment and save space. Therefore, display device manufacturers are dedicated to designing thinner and lighter displays to meet market demands.

[0027] In addition, consumers not only pursue thinner and lighter display devices, but also improved performance. As the sound source device of the display device, the acoustic device is an important component. Good sound quality can effectively enhance the immersive experience and enjoyment of consumers when watching the display device.

[0028] However, as the overall thickness of display devices gradually decreases, the effective internal space is gradually compressed. When the overall thickness is reduced to a certain threshold, further reduction will lead to the compression of the volume of some internal components, such as acoustic devices, resulting in a decrease in sound quality. Furthermore, further reduction in thickness will significantly increase the design complexity and cost of the internal components. In the overall product design of display devices, it is already difficult to further reduce the thickness of the display screen and the back panel. Therefore, in this situation, to achieve further reduction in the overall thickness of the display device, space compression is usually required in the design of acoustic devices, but this inevitably leads to a decrease in sound quality.

[0029] Therefore, as consumers' demands for both the appearance and functionality of display devices continue to increase, ensuring that various performance indicators (especially acoustic performance) meet the standards while maintaining an ultra-thin design has become a challenge for display device manufacturers.

[0030] In view of this, embodiments of this application propose a display device that can further reduce the design thickness of the display device at a lower cost and with less design difficulty, without sacrificing the performance of the acoustic device.

[0031] It should be noted that the display device proposed in the embodiments of this application can be a complete television set, a monitoring screen, an independent monitor, a laptop computer, a tablet computer, a smartphone, or other terminal devices with image display and sound output functions.

[0032] Figure 1 This is a schematic diagram of the structure of a display device 100 according to an embodiment of this application. Figure 1 This is a vertical cross-sectional view of the display device 100, with the cross-section perpendicular to the display screen of the display device 100.

[0033] refer to Figure 1 As shown, the display device 100 includes:

[0034] The rear cover 110 of the whole machine includes a first opening 111;

[0035] The acoustic device 120 has a first sidewall 121 including a protrusion 122 located at a first opening 111 and fitting with the first opening 111.

[0036] In some possible embodiments, the acoustic device 120 described above can be a sound-generating device that can serve as a sound source for the display device 100, such as a speaker, audio equipment, or the like.

[0037] In some possible embodiments, the display device 100 may further include a display screen 101 and a back panel 102, which are fixed together. Furthermore, the rear shell 110 is fixed to the back panel 102 to form a cavity, within which the acoustic device 120 is located. Of course, other components may also be included within this cavity, but these other components are not necessarily located within the cavity. Figure 1 As shown in the image.

[0038] In some possible embodiments, the above-mentioned protrusion 122 being located in the first opening 111 means that the protrusion 122 corresponds to the first opening 111 in physical position, for example, the protrusion 122 being located within the boundary of the first opening 111.

[0039] In some possible embodiments, the engagement of the protrusion 122 with the first opening 111 means that the shape and size of the protrusion 122 are designed to match the first opening 111. For example, the contour, curvature, height and other parameters of the protrusion 122 are matched with the corresponding parameters of the first opening 111 so that the two can fit together tightly during assembly or installation.

[0040] Based on the matching relationship between the first sidewall 121 of the acoustic device 120 and the first opening 111 of the rear shell 110, it can be understood that the first sidewall 121 of the acoustic device 120 is a part of the rear shell 110.

[0041] In current display device designs, the acoustic device and the back cover of the device are two structurally independent parts. Therefore, the design requires a certain gap between the first sidewall of the acoustic device and the back cover of the device. This is to prevent the vibration generated by the acoustic device from contacting the back cover of the device. Otherwise, the vibration of the acoustic device would cause the first sidewall to collide directly with the back cover of the device, causing the acoustic device and the back cover of the device to resonate, which would then cause the display device to emit resonant noise when it is emitting sound.

[0042] However, in the display device 100 proposed in this application embodiment, the first sidewall 121 of the acoustic device 120 is embedded in the first opening 111 left in the back shell 110 of the whole machine. Therefore, even if the acoustic device 120 generates corresponding vibration when it emits sound, since the back shell 110 of the whole machine is equivalent to the first sidewall 121 of the acoustic device 120 as an integral structure, the first sidewall 121 of the acoustic device 120 will not collide with other internal components when it vibrates, so no resonance noise will be generated.

[0043] For example, in the current design of display devices, the first sidewall of the acoustic device can usually be designed to be at least 2.5mm thick, the rear shell of the whole device can usually be designed to be at least 2.5mm thick according to the required size of the whole device, and the gap between the first sidewall of the acoustic device and the rear shell of the whole device can usually be designed to be at least 3mm thick. Therefore, the sum of the thickness of the first sidewall, the gap and the thickness of the rear shell of the whole device is at least 8mm.

[0044] Based on the display device 100 proposed in this application embodiment, there is no gap between the first sidewall 121 of the acoustic device 120 and the back cover 110 of the whole machine, and the first sidewall 121 is embedded in the first opening of the back cover 110 of the whole machine, and the two fit together. Therefore, it is equivalent to combining the first sidewall 121 and the back cover 110 of the whole machine. The thickness of the two after being combined can usually be designed to be at least 2.5mm according to the required size of the whole machine. Therefore, the sum of the thickness of the first sidewall and the thickness of the back cover of the whole machine can reach at least 2.5mm. So compared with the current display device design, the design scheme proposed in this application embodiment can save at least 5.5mm of spare space.

[0045] Therefore, based on the structural design of the display device 100 in the above embodiments, the empty space inside the cavity formed between the back cover 110 and the back plate 102 of the whole machine can be effectively increased, and the empty space provides more design margin for the structural design of the display device 100.

[0046] In some possible embodiments, in the overall product design, the volume of the acoustic device 120 can be kept unchanged, while the thickness of the display device 100 can be compressed, that is, the space inside the cavity of the back cover 110 of the whole device can be compressed towards the back panel 102 of the whole device, for example, by 5.5mm, thereby making the display device 100 thinner and lighter. Moreover, since the volume of the acoustic device 120 remains unchanged, the sound performance of the acoustic device 120 will not be sacrificed, that is, the sound quality will not be reduced.

[0047] In some possible embodiments, in the overall product design, the space inside the cavity of the rear shell 110 of the whole machine can be kept unchanged, and the extra space can be used to design a larger acoustic device 120, so that the acoustic device 120 has stronger power resistance, thereby further enhancing the sound quality of the acoustic device 120.

[0048] Testing has shown that in a design where the overall thickness of the display device is reduced by 20%, the width of the acoustic device can be increased by 17% to 20%, and the power of the acoustic device can be increased by more than 50%. Furthermore, with the increase in the width of the acoustic device, the low-frequency response is also improved, with low-frequency response performance parameters increasing by more than 30%. Moreover, if the above performance parameters were achieved using a conventional display device design, the manufacturing cost would increase by more than 40%.

[0049] Based on the above technical solutions, the thickness of the display device can be further reduced at a lower cost and with less design complexity without compromising the size of the acoustic device, resulting in a thinner and lighter overall appearance. Alternatively, the size of the acoustic device can be further increased at a lower cost and with less design complexity without compromising the thickness of the display device, thereby improving the sound quality of the acoustic device.

[0050] Figure 2 This is yet another structural schematic diagram of the display device 100 proposed in this application embodiment. Figure 2 This is a vertical cross-sectional view of the display device 100, and the cross-section is parallel to the display screen of the display device 100.

[0051] In some possible embodiments, reference Figure 2 As shown, the aforementioned rear shell 110 further includes N first connecting portions 112; the aforementioned acoustic device 120 further includes N second connecting portions 123, and the positions of the N second connecting portions 123 correspond one-to-one with the positions of the N first connecting portions 112; the aforementioned display device 100 further includes N fixing mechanisms 130, where N is a positive integer greater than 1; wherein, the first connecting portions 112 and the second connecting portions 123 are fixed by the fixing mechanisms 130.

[0052] exist Figure 2 In the example shown, N=4, which effectively ensures the stability of the fixation between the acoustic device 120 and the rear shell 110 of the whole machine.

[0053] In some possible embodiments, the aforementioned fixing mechanism 130 includes an elastic material.

[0054] In some possible embodiments, the hardness of the elastic material applied to the fixing mechanism 130 can be in the range of [25, 45] based on Shore A hardness. For acoustic devices 120 with different operating parameters (e.g., power) and structural parameters, the hardness of the elastic material of the fixing mechanism 130 can be adaptively adjusted within this hardness range.

[0055] In some possible embodiments, the fixing mechanism 130 includes an elastic material such as rubber, silicone, or plastic.

[0056] In some possible embodiments, the fixing mechanism 130 includes a rubber pad 131 and a fixing part 132, wherein the fixing part 132 is used to fix the first connecting part 112, the second connecting part 123 and the rubber pad 131.

[0057] Figure 3 This is yet another structural schematic diagram of the display device 100 proposed in this application embodiment. Figure 3 It is a vertical cross-sectional view of the display device 100, and the cross-section is parallel to the side of the display device 100.

[0058] In some possible embodiments, the first connecting portion 112 may be a rod-shaped structure, and the second connecting portion 123 may be a tubular structure, with the first connecting portion 112 insertable into the second connecting portion 123. (See reference...) Figure 3 As shown, in order to prevent the vibration generated when the acoustic device 120 emits sound from being transmitted to the back cover 110 of the whole machine through the second connecting part 123 and the first connecting part 112, causing the display device 100 to resonate and generate noise, the above-mentioned rubber pad 131 can be wrapped around the first connecting part 112 and the second connecting part 123 to absorb the vibration transmitted to the second connecting part 123 and the first connecting part 112.

[0059] In some possible embodiments, reference Figure 3 As shown, the fixing part 132 can be a plastic column buckle. The plastic column buckle can include a column semicircular structure. The two column semicircular structures are respectively fastened to both sides of the rubber pad, and the two column semicircular structures are fixed by the buckle, thereby fixing the first connecting part 112, the second connecting part 123 and the rubber pad 131.

[0060] In some possible embodiments, the fixing part 132 may also be a screw assembly, thereby fixing the first connecting part 112, the second connecting part 123 and the rubber pad 131 by screw fastening.

[0061] In some possible embodiments, when there is a gap between the inner ring of the second connecting portion 123 and the first connecting portion 112, the gap can also be filled with an elastic material.

[0062] In some possible embodiments, in Figure 3 In the structure shown, the first connecting part 112 located in the rear shell 110 of the whole machine is a rod-shaped structure, and the second connecting part 123 located in the acoustic device 120 is a tubular structure adapted to it. The structural forms of the first connecting part 112 and the second connecting part 123 can be interchanged, that is, the first connecting part 112 can be a tubular structure and the second connecting part 123 can be a rod-shaped structure. Under this structural design, the second connecting part 123 can be inserted into the first connecting part 112, and the fixing method of the fixing mechanism 130 with the first connecting part 112 and the second connecting part 123 remains unchanged.

[0063] Based on the above technical solution, it is possible to further prevent the transmission of vibrations from the acoustic device 120 when they occur, which helps to avoid the vibrations from being transmitted to other components and causing resonance, thus generating resonance noise.

[0064] In some possible embodiments, the aforementioned N first connecting portions 112 are evenly distributed on the rear shell 110 of the whole machine.

[0065] It should be understood that since the positions of the N fixing mechanisms 130 and the N second connecting parts 123 correspond one-to-one with the N first connecting parts 112, the N fixing mechanisms 130 and the N second connecting parts 123 are also evenly distributed in the cavity between the rear shell 110 and the back plate 102 of the whole machine.

[0066] In some possible embodiments, when N is a multiple of 2, then N / 2 first connecting portions 112 are evenly distributed on the left half of the rear shell 110 and N / 2 first connecting portions 112 are evenly distributed on the right half of the rear shell 110.

[0067] It should be understood that when the above-mentioned N first connecting parts 112 are evenly distributed on the back cover 110 of the whole machine, or half of them correspond to the left half of the back cover 110 of the whole machine and the other half corresponds to the right half of the back cover 110 of the whole machine, the balance between the weight of the left half and the right half of the display device 100 can be effectively guaranteed.

[0068] In some possible embodiments, the distribution of the above-mentioned N first connecting parts 112 can also be in other forms, as long as the weight balance between the left and right halves of the display device 100 can be achieved based on the specified distribution.

[0069] Figure 4 This is a schematic diagram of the structure of a rear shell 110 of a complete machine according to an embodiment of this application.

[0070] In some possible embodiments, reference Figure 4As shown, the rear cover 110 of the whole machine also includes a sound outlet array 113.

[0071] In some possible embodiments, the rear cover 110 may include one or more sound outlet arrays 113, for example, Figure 4 The rear cover 110 shown includes two sound outlet arrays 113.

[0072] In some possible embodiments, the above-described sound outlet array 113 includes a textured pattern.

[0073] The texture pattern can be a specially designed pattern used to represent the visibility of acoustic elements. This pattern may include CD-pattern acoustic elements, a texture pattern consistent with the texture of the back cover 110, or other special texture patterns. Furthermore, the specially designed texture pattern can serve as identification information for the display device 100.

[0074] Based on the above technical solution, both the visual appearance of the display device's acoustics and the identification elements of the display device can be achieved.

[0075] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
