According to the size of the display device 100, the height direction of the sound box assembly 10, that is, the size of the vertical up and down direction when the display device 100 is vertically placed is consistent with the size of the display device 100, for example, in the display device 100 with a 75-inch, 80-inch or larger screen, the sound box assembly 10 can have a volume of 2.5 liters or more, so as to provide better sound quality. And the sound box assembly 10 is arranged on the side part of the display device 100, which can directly emit sound to the front side of the display device 100 when playing sound, reducing the excessive interference of the reflected sound of the wall or other objects on the direct sound of the sound box, and obtaining a good positioning feeling and a wide and deep sound field, so that the user can hear the most, the most direct and the clearest details.

[0039] As shown, two sound box assemblies 10 are arranged on the two side parts of the display device 100 respectively, the upper and lower ends of the sound box assembly 10 can be flush with the upper and lower ends of the display device 100 respectively, so as to improve the internal space of the sound box assembly 10, so that the sound quality of the played sound is better, especially for bass, the improvement of the sound box space can improve the listening experience and achieve a shocking bass effect. According to the size of the display device 100, the height direction of the sound box assembly 10, that is, the size of the vertical up and down direction when the display device 100 is vertically placed is consistent with the size of the display device 100, for example, in the display device 100 with a 75-inch, 80-inch or larger screen, the sound box assembly 10 can have a volume of 2.5 liters or more, so as to provide better sound quality. And the sound box assembly 10 is arranged on the side part of the display device 100, which can directly emit sound to the front side of the display device 100 when playing sound, reducing the excessive interference of the reflected sound of the wall or other objects on the direct sound of the sound box, and obtaining a good positioning feeling and a wide and deep sound field, so that the user can hear the most, the most direct and the clearest details. Figures 1-4As shown, the sound box assembly 10 can include a housing 11, a cavity is formed in the housing 11, and a connecting component 12 is arranged on the housing 11, wherein the connecting component 12 is used to connect with the display device 100; a speaker 13 is arranged in the cavity of the housing 11, and the sound image center is located at the center position of the display device 100 when playing sound; wherein the speaker 13 can include a middle sound speaker 132 arranged in the middle of the housing 11, and a low sound speaker 131 and a high sound speaker 133, one of which is arranged above the middle sound speaker 132, and the other is arranged below the middle sound speaker 132.

[0040] In the embodiment, the connecting component 12 can be directly connected with the housing 11, or can be fixedly connected with the housing 11 through a connecting component, and at the same time, the connecting component 12 is connected with the display device 100, so as to connect the sound box assembly 10 with the display device 100. The display device 100 can include a movable moving component for driving the connecting component 12 to move, so that the sound box assembly 10 can move, which will be described in the related embodiments below.

[0041] According to the arrangement mode of the sound box assembly 10 described above, the cavity formed by the housing 11 forms a larger space, so as to improve the sound quality, especially the low frequency sound emitted by the low sound speaker 131, which can produce better bass effect through the large space cavity.

[0042] In addition, in the embodiment, the number of low sound speakers 131, middle sound speakers 132 and high sound speakers 133 can be one or more, and in the drawings of the present disclosure, two low sound speakers 131, one middle sound speaker 132 and one high sound speaker 133 are taken as an example, but the present disclosure is not limited to this. The middle sound speaker 132 is located in the middle of the housing 11, and can be arranged close to the middle position in the vertical direction of the display device 100. The low sound speaker 131 can be located above the middle sound speaker 132, and the high sound speaker 133 can be located below the middle sound speaker 132; or the low sound speaker 131 can be located below the middle sound speaker 132, and the high sound speaker 133 can be located above the middle sound speaker 132. Through the above arrangement, the sound image center can be located at the middle height when playing sound, and through the left and right two sound box assemblies 10, the sound image can be located at the center position of the display device 100, so that when watching the picture of the display device 100, the virtual sound source of the sound heard is the same as the picture position, which can bring better experience to people.

[0043] In an embodiment, as shown in FIG. 1, the display device 100 can include a display screen 101, a frame 102, and a sound box assembly 10, wherein the sound box assembly 10 is arranged on the frame 102, and the sound box assembly 10 is connected with the display device 100 through the connecting component 12.

In this embodiment, according to different audio ranges and the audio range in which general sound is generally located, the above arrangement can achieve a sound image of the sound played from the speaker 13 located at an intermediate height, and through the left and right two sound box assemblies 10, the sound image can be located in the center of the display device 100, and the sound and picture can be realized on the same screen, i.e. the virtual sound source is located on the screen 20 of the display device 100.

[0044] In an embodiment, as shown in Figure 1 、 Figure 3 , the sound box assembly 10 can further include: an inverse pipe structure 14, the inverse pipe structure 14 being arranged inside the shell 11; and the inverse pipe structure 14 being arranged in a position corresponding to the woofer 131. In this embodiment, the inverse pipe structure 14 is arranged inside the shell 11, and the inverse pipe structure 14 is a device that can conduct vibrations from the rear of the speaker to the front, so that the sound waves from the front and the rear of the speaker are both utilized, and the sound quality of the sound box is improved. Moreover, according to the principle of the inverse pipe structure 14, it can especially enhance the electric sound performance, and the bass can be dived to 42Hz, so that the inverse pipe structure 14 is arranged in a position corresponding to the woofer 131, i.e. the woofer 131 is located in the upper part of the shell 11, and the inverse pipe structure 14 is located in the lower part of the shell 11, or the woofer 131 is located in the lower part of the shell 11, and the inverse pipe structure 14 is located in the upper part of the shell 11, so as to further ensure that the sound image of the sound box assembly 10 is located in the middle position.

[0045] In an embodiment, as shown in Figure 2 、 Figure 3 , the sound box assembly 10 can further include: a bracket 15, the bracket 15 being arranged inside the shell 11, the bracket 15 being provided with mounting holes 151 corresponding to the positions of the speakers 13, and the speakers 13 being respectively mounted in the mounting holes 151; the bracket 15 being provided with sound guide holes 152, and the sound guide holes 152 being provided with sound guide grooves 141 on the back side; the sound guide grooves 141 being arranged with openings facing the direction of the woofer 131, and the sound guide grooves 141 being connected with the back side of the bracket 15 to form the inverse pipe structure 13.

[0046] In this embodiment, the shell 11 can be provided with a support 15, and the support 15 is provided with mounting holes 151 for mounting the speakers 13. The number, position and size of the mounting holes 151 can be determined according to the number, position and corresponding structure of the bass speakers 131, the medium speakers 132 and the treble speakers 133. The speakers 13 are mounted in the mounting holes 151, and the front surface of the speakers 13 faces the front side, i.e., the side of the screen 20 of the display device 100 on which the picture is displayed, and the back surface of the speakers 13 can be connected to the control circuit, the power supply circuit and the like through the wires 134 from the back side of the support 15.

[0047] The support 15 is also provided with sound guide holes 152, and the back side of the sound guide holes 152 is provided with sound guide grooves 141 connected to the back side of the support 15 and having an opening at one end, which faces the direction of the bass speakers 131, so as to collect the vibration of all the speakers 13 at the back side and then transmit the sound to the front side through the sound guide holes 152 and play it out.

[0048] In some embodiments, the support 15 can be further provided with a connecting plate 153, which can be used to connect with the connecting member 12. Since the support 15 is provided with the speakers 13, it has a relatively large weight, and the connecting member 12 is directly connected to the connecting plate 153, so as to reduce the force bearing support member and directly support the sound box assembly 10. In some embodiments, as shown in Figure 2 、 Figure 3 The sound box assembly 10 can further include a reinforcing member 16, which can be fixedly installed on the support 15 to play a reinforcing role, and the connecting member 12 can also be connected to the reinforcing member 16 to achieve multi-point connection and multi-point support, so that the connection of the sound box assembly 10 is more stable and reliable.

[0049] In an embodiment, as shown in Figures 3 to 7 The sound box assembly 10 is connected to the moving mechanism (not shown in the figure) of the display device 100 through the connecting member 12 and can move between a first position and a second position in the left-right direction of the display device 100, wherein the first position is located at the back side of the screen 20 of the display device 100, and the second position is located at the left side or the right side of the screen 20; the sound box assembly 10 can further include a distance sensor 17 provided on the side of the shell 11 away from the screen 20, and if the distance detected by the distance sensor is less than or equal to a distance threshold value, the sound box assembly is prohibited from moving to the second position.

[0050] The left and right directions generally refer to the straight line direction of the screen 20 of the display device 100 when the display device 100 is in use, i.e., the screen 20 faces the front side, and the left and right sides of the display device 100. When the display device 100 is vertically placed, i.e., the screen 20 is perpendicular to the horizontal plane, the left and right directions are horizontal directions. In the embodiment, the sound box assembly 10 can be moved relative to the screen 20. The display device 100 can include a movable moving component and a driving component that can drive the moving component to move, etc. The sound box assembly 10 can be connected to the moving component through the connecting component 12. The display device 100 drives the moving component to move, thereby driving the sound box assembly 10 to move between the first position and the second position. The first position can be located at the back side of the screen 20 and close to the left and right side ends of the screen 20. When the sound box assembly 10 is located at the first position, the user cannot observe the sound box assembly 10 from the front side of the display device 100. The second position can be on the left side or the right side of the screen 20, corresponding to the first position close to the left side end of the screen 20, extending out of the back side of the screen 20 to the left. When the sound box assembly 10 is located at the second position, it exceeds the boundary of the left side of the screen 20, so that the loudspeaker 13 is completely exposed, and the user can observe the sound box assembly 10 from the front side of the display device 100. The sound emitted by the sound box assembly 10 can also be conveyed to the user without being blocked or reflected. Corresponding to the first position close to the right side end of the screen 20, there is also a second position on the right side of the screen 20. The principle is the same as the second position on the left side described above, and will not be described again. In the audio output state, i.e., when sound needs to be played, for example, in the state of starting up or playing a program after the display device 100 is started up, the sound box assembly 10 can be moved to the second position to be exposed from the left side or the right side of the screen 20 of the display device 100, so as to emit sound to the front side, thereby avoiding damage to the sound quality. When the audio output state is exited, i.e., when sound does not need to be played, for example, in the state of shutdown or standby of the display device 100, the sound box assembly 10 can be moved to the first position, i.e., located at the back side of the screen 20, so that the appearance of the display device 100 is simple and beautiful. The sound box assembly 10 can be stored in the shell of the display device 100. The moving mode can be linear movement or flip movement, etc.

[0051] In addition, a distance sensor 17 can be arranged on the side of the shell 11, i.e., the side away from the screen 20, for detecting whether there is an object outside the shell 11 and the distance to the object. For example, Figure 7As shown, objects 200 can be placed on both sides of the display device 100, and the objects 200 can collide with the sound box assembly 10 when the sound box assembly 10 moves outward. Therefore, the distance sensor 17 is used for detection, and when it is detected that the distance of the object 200 is less than or equal to the distance threshold, the sound box assembly 10 can be prohibited from moving to the second position, so as to avoid the object from falling or colliding, and also avoid damage to the sound box assembly 10. The distance threshold can be equal to the distance between the second position and the first position, or can be slightly greater than the distance to make the movement more reliable. For example, the distance of the sound box assembly 10 extending out, that is, the distance between the second position and the first position, is 100 mm, and the distance threshold can be set to 120 mm, and the detection angle of the distance sensor 17 can be greater than or equal to 120 degrees to ensure the reliability of the detection.

[0052] In an embodiment, the distance sensor 17 can include a first distance sensor 171 located at the lower part of the shell 11. Generally, objects are placed on the ground or a table, and therefore the objects generally extend from the lower part to the upper part. In this embodiment, the first distance sensor 171 is located at the lower part of the shell 11 and faces outward, which can better detect the objects and avoid being arranged at a high position and failing to detect the objects.

[0053] In an embodiment, the distance sensor 17 can further include one or more second distance sensors 172 located above the first distance sensor 171. In some cases, objects placed on the side of the display device 100 can be of an irregular shape, such as some vases that are narrow at the lower part and wide at the upper part, or objects extending from the side, etc., which can cause the first distance sensor 171 arranged below to fail to detect objects located in the middle or above. In order to better detect the objects and avoid collision, this embodiment can further include one or more second distance sensors arranged above the first distance sensor 171. For example, as shown in Figure 4 The second distance sensor 172 can be arranged only at the middle part of the shell 11, and the distance L between the second distance sensor 172 and the first distance sensor 171 can be 400 mm or other values.

[0054] In an embodiment, as shown in Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the shell 11 can include a cloth net 111 covering the front outer surface of the shell 11. In this embodiment, the cloth net 111 can be made of canvas or other materials, and the appearance is simple by arranging the cloth net 111 on the outer side of the shell 11. The cloth net 111 can cover the front side, the upper side, the lower side, and the outer side of the shell 11, so that the surfaces that can be observed are integrally arranged.

[0055] In an embodiment, as shown in Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 , the shell 11 can further include a mesh frame 112 and a back shell 113; the mesh frame 112 and the back shell 113 are buckled to form a cavity; the mesh frame 112 includes a sound outlet area 1121 corresponding to the position of the speaker 13; the cloth mesh 111 is arranged on the outer surface of the mesh frame 112. In this embodiment, the mesh frame 112 can be made of plastic and connected to the back shell 113 by buckling or other means. The connecting part 12 in the foregoing embodiment and the connecting plate 153 on the support 15 can extend out of the cavity. The mesh frame 112 can be provided with a sound outlet area 1121 in a hollow or other manner corresponding to the position of the speaker 13 to avoid affecting the sound outlet of the speaker 13. In some embodiments, the mesh frame 112 is also a sound outlet area 1121 corresponding to the sound guide hole 152. The cloth mesh 111 can be attached to the outer surface of the mesh frame 112 by spraying glue or other means, making installation simple. As shown in Figure 5 , the front side of the shell 11 is mainly formed by the cloth mesh 111 and the mesh frame 112, the cloth mesh 111 and the mesh frame 112 are matched and can be arranged on the front side of the mesh frame 112 and the side end surface of the mesh frame 112, Figure 6 shows a local schematic view of the combination of the cloth mesh 111 and the mesh frame 112, as shown in Figure 6 , the cloth mesh 111 is arranged on the front side (such as the A side of Figure 6 ) and the side end surface (such as the B side of Figure 6 ) of the mesh frame 112. This arrangement can form an integrated visual effect on the appearance of the sound box assembly 10 and improve user experience. In addition, as shown in Figure 5 , the distance sensor 17 is arranged on the side of the sound box assembly 10, and as shown in Figure 6 , a through hole is formed on the side end surface of the mesh frame 112, and a corresponding position of the cloth mesh 111 is also provided with a through hole, the first distance sensor 171 is arranged inside the shell 11, i.e. inside the through hole formed on the side end surface of the mesh frame 112, the first distance sensor 171 can be installed on the cloth mesh 111 by clamping, and the through hole formed by the mesh frame 112 and the cloth mesh 111 can detect external objects and their distance.
