[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] Display devices, such as LED all-in-one machines, usually include multiple LED boxes arranged in an array. The multiple LED boxes can be spliced ​​together to form a display surface. On this display surface, a corresponding LED light board can be set on each LED box, so that the LED light boards respectively set on the multiple LED boxes are spliced ​​to form a display screen of the display device for displaying pictures.

[0026] In the conventional technology, a display device is usually provided with a corresponding speaker module beside a main body formed by splicing LED boxes, and the speaker module can be used for sound.

[0027] For example, corresponding speaker modules are respectively arranged on both sides of the main body formed by splicing LED boxes, or corresponding speaker modules are arranged on the front and / or rear sides of the main body formed by splicing LED boxes, or corresponding speaker modules are arranged on one or several sides of the main body formed by splicing LED boxes, which is not limited here.

[0028] The defect of the prior art is that since the speaker modules are usually located on one side, both sides or multiple sides of the main body formed by splicing the LED boxes of the display device, no matter how many speaker modules are arranged at different positions next to the main body, since the positions of the speaker modules are concentrated on several positions on one side, both sides or multiple sides next to the main body, all the speaker modules can only make sounds at these limited positions. In the use scenario where the display device is an LED all-in-one machine, it is easy to cause the sound waves emitted by all the speaker modules to fail to evenly cover the entire area where the user is located, resulting in poor sound effects.

[0029] In order to solve the above-mentioned problem, the present application proposes a display device, in which a plurality of speaker modules are respectively arranged in corresponding LED boxes. Since the plurality of LED boxes are arranged in an array, the plurality of speaker modules can form a plurality of sound sources arranged in an array. Sound is loudspeakered based on the plurality of sound sources, so that the sound waves emitted by all the speaker modules are emitted from the plurality of LED boxes arranged in the array and evenly cover the area toward which the display device is facing, thereby improving the uniform coverage of the speaker and improving the speaker effect.

[0030] This application first proposes a display device, see Figure 1 , Figure 1 is a schematic structural diagram of an embodiment of the display device of the present application. Figure 1 As shown, the display device includes a plurality of LED boxes 1 and a plurality of speaker modules 2 arranged in an array.

[0031] A plurality of LED boxes 1 are spliced ​​together.

[0032] The splicing method may specifically be hoisting, fixed installation or seat installation, or other types of splicing methods, which are not limited here.

[0033] A plurality of LED boxes 1 can be spliced ​​together to form a main body for placing an LED light board for fixing and protecting. Generally speaking, if the LED boxes 1 remain unchanged, the more LED boxes 1 there are, the larger the main body formed by splicing will be and the larger the area of ​​the LED light board that can be placed will be. In one example, one LED box 1 can be used to place one LED light board, and in other examples, one LED box 1 can also be used to place more than two LED light boards, which is not limited here.

[0034] The material of the LED box 1 can be iron, aluminum alloy, stainless steel, carbon fiber, magnesium alloy or nano polymer material. The LED box 1 mainly plays a fixing and protective role. The LED box 1 is used to place the LED light board to realize the picture display through the LED light board.

[0035] Each speaker module 2 is disposed in a corresponding LED box 1 for performing a speaker operation at the box.

[0036] Among them, since the multiple LED boxes 1 are arranged in an array and spliced ​​with each other, and the multiple speaker modules 2 are respectively set in a corresponding LED box 1, for example, each LED box 1 can be respectively provided with a speaker module 2. Based on the above method, the speaker modules 2 can also be distributed in an array, and a sound source arranged in an array can be formed on a main body for setting an LED light board formed by splicing multiple LED boxes 1. It can be used for displaying pictures on the LED light boards arranged in an array on the multiple LED boxes 1. At the same time, in the area where the picture is displayed, the sound source arranged in an array is used to perform sound, so that the sound waves generated by the speaker can evenly cover the position of the user watching the picture, thereby improving the uniform coverage of the speaker and increasing the sound density per unit area to improve the speaker effect.

[0037] Different from the prior art, the present application provides a display device including a plurality of LED boxes arranged in an array, the plurality of LED boxes are spliced ​​with each other, and a plurality of speaker modules, each speaker module is respectively arranged in a corresponding LED box, and is used to perform sound at the box. Based on the above method, the plurality of speaker modules can be respectively arranged in the corresponding LED boxes, and because the plurality of LED boxes are arranged in an array, the plurality of speaker modules can form a plurality of sound sources arranged in an array, and sound is performed based on the plurality of sound sources, so that the sound waves emitted by all the speaker modules can evenly cover the area facing the display device, thereby improving the uniform coverage of the sound, and thus improving the sound effect.

[0038] In one embodiment, see Figure 2 , Figure 2 is a schematic structural diagram of another embodiment of the display device of the present application. Figure 2 As shown, the LED box 1 described in the previous embodiment is not shown in the figure, and the display device also includes a sending card module 3.

[0039] The sending card module 3 is connected to each speaker module 2 respectively, and the sending card module 3 is used to send the received audio signal to the speaker module 2 .

The sending card module 3 can be used to receive video signals and transmit the video signals to the LED light board through the link of the sending card module 3, the receiving card module and the LED light board, so as to realize the control of the display device to display the picture.

[0041] In the present embodiment, by connecting the sending card module 3 to the speaker modules 2 in each LED box 1, the sending card module 3 can also be used to receive audio signals, and transmit the audio signals to the speaker module 2 through the link from the sending card module 3 to the speaker module 2, so as to control the display device to perform sound.

[0042] In one example, if Figure 2 As shown, the speaker module 2 includes an interconnected power amplifier unit 21 and a speaker unit 22.

[0043] Based on the above method, the provision of audio signals to the speaker modules 2 in each LED box 1 can be achieved through the sending card module 3 without additionally setting up other signal transmission devices. Under this premise, the provision of audio signals to the speaker modules 2 outside the LED box 1 can also be achieved through the sending card module 3. That is, based on this link, the user can freely choose to perform sound through the speaker module 2 in the LED box 1, or through the speaker module 2 outside the LED box 1, or through all the speaker modules 2 at the same time, thereby improving the compatibility and flexibility of the audio signal transmission link of the display device, and can also reduce the cost required for sound transmission using an array-arranged sound source as much as possible.

The second processing unit 32 can be used to obtain audio signals from the storage space connected to its system to send the audio signals to the first processing unit 31 for analysis, and can also be used to configure the power amplifier unit 21 and / or the speaker unit 22.

[0049] In one example, the first processing unit 31 can obtain and parse the audio signal through the HDMI cable or external sound card or network card connected thereto, and transmit the parsed audio signal to the power amplifier unit 21 through the IIS bus for amplification. In addition, the second processing unit 32 can obtain the audio signal through the microphone or storage module connected thereto, and the first processing unit 31 can obtain and parse the audio signal from the second processing unit 32, and transmit the parsed audio signal to the power amplifier unit 21 through the IIS bus for amplification.

[0050] The second processing unit 32 can also configure the power amplifier unit 21 through the IIC bus, so that the power amplifier unit 21 can better realize the sound and improve the sound effect.

[0051] Based on the above method, the speaker module 2 in the LED box 1 can be controlled by the sending card module 3 to perform a speaker operation that meets the needs of the user, thereby improving the reliability of the display device.

The sending card module 3 can be used to receive video signals and transmit the video signals to the LED light board through the link of the sending card module 3, the receiving card module and the LED light board, so as to realize the control of the display device to display the picture.

[0055] In this embodiment, by connecting the receiving card module 4 to the speaker module 2 in the LED box 1 where it is located, the audio signal can be received by the sending card module 3, and the audio signal is transmitted to the speaker module 2 through the relay of the receiving card module 4, so as to control the display device to speak.

[0056] In one example, if Figure 3 As shown, the speaker module 2 includes an interconnected power amplifier unit 21 and a speaker unit 22. The sending card module 3 is respectively connected to each power amplifier unit 21. The sending card module 3 can send an audio signal to the power amplifier unit 21, or configure the power amplifier unit 21 and / or the speaker unit 22, or other types of communication operations through a communication connection with the power amplifier unit 21, which is not limited here.

[0057] Based on the above method, the provision of audio signals to the speaker modules 2 in each LED box 1 can be achieved without setting up other additional signal transmission devices, and the cost required for achieving sound transmission using array-arranged sound sources can be reduced as much as possible.
