[0002] With the continuous progress of technology, intelligent display devices have become an indispensable part of people's daily lives. Traditional electronic devices such as TVs and display screens have gradually been replaced by intelligent display devices because their single display screens cannot meet people's increasingly high usage requirements. For example, a dual-screen TV is an innovative intelligent TV that adopts a dual-screen design. The main screen is used for watching content, and the secondary screen can be used to display other information or perform multitasking. When needed, the secondary screen can be used as an extension of the main screen to display a larger picture, thereby enhancing the visual effect and providing a better user experience.

[0003] However, although the display screens of display devices are getting larger, the sound-emitting effect of the speakers equipped on the display devices is limited. Moreover, in traditional designs, the sound-emitting holes of the speakers are only designed facing the speakers themselves. Therefore, for large-sized intelligent display devices, the sound often only comes out from a local area, and the sound-emitting effect fails to meet the usage requirements, affecting the market competitiveness of the products.

[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0052] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9 shown, in an embodiment of the present invention application, a full-surface sound-emitting speaker assembly 10 for a display device 20 is disclosed; wherein, the speaker assembly 10 includes a main board 11, a first bracket 12, a second bracket 13, a sound component 14, a dust-proof net 15, and a panel 16, and the main board 11 is connected to the display device 20; a support grille 111 is formed by locally hollowing out the main board 11; the first bracket 12 and the second bracket 13 are provided on the back surface of the main board 11; and, the first bracket 12 and the second bracket 13 are respectively located on both sides of the support grille 111; one end of the sound component 14 is connected to the first bracket 12, and the other end is connected to the second bracket 13; the sound outlet of the sound component 14 faces the support grille 111; the dust-proof net 15 is provided on the front surface of the main board 11 for covering the support grille 111; the panel 16 is provided on the front surface of the main board 11 and covers the dust-proof net 15; sound outlet holes 161 are provided in the whole surface of the panel 16.

[0053] The display device 20 disclosed in this embodiment includes, but is not limited to, common dual-screen TVs, large-size display screens, large-size flat-panel TVs, etc. in daily life. In order to match the increasingly better display effects, it has become inevitable to configure high-power speakers on the display device 20. The sound component 14 disclosed in this embodiment includes, but is not limited to, speakers applied to electronic devices, such as dynamic coil speakers and capacitive speakers.

[0054] Specifically, the speaker assembly 10 disclosed in this embodiment is connected to the display device 20 through the main board 11. A support grille 111 is formed by hollowing out the main board 11, and a first bracket 12 and a second bracket 13 are provided on the back of the main board 11 to support the sound component 14, so that the sound component 14 is suspended and fixed, and the sound outlet is aligned with the support grille 111. In this way, during use, the vibration of the sound component 14 will not be transmitted to the main board 11, avoiding the negative impact of resonance and reducing problems such as noise and vibration. At the same time, the sound directly propagates forward through the support grille 111.

[0055] As Figure 2 shown, a dust-proof net 15 is provided on the front of the main board 11, covering the support grille 111, thereby reducing dust ingress, making the service life of the sound component 14 longer, and being beneficial to maintaining high-quality sound effects for a long time. And, a panel 16 is covered outside the dust-proof net 15. The size of the panel 16 is equivalent to that of the main board 11, covering the front of the main board 11. Therefore, the appearance is beautiful. Sound outlet holes 161 are provided on the front of the panel 16. Therefore, when the sound passes through the support grille 111, it spreads between the panel 16 and the main board 11 and finally exits from the entire surface of the panel 16, achieving the effect of sound output from the entire surface.

[0056] Structurally speaking, the speaker assembly 10 disclosed in this embodiment is provided with sound outlet holes 161 on the entire surface of the panel 16, increasing the sound output area, which is beneficial to the rapid transmission of sound by high-power speakers. Moreover, the sound is emitted from various positions of the panel 16, and the overall sound effect is good, avoiding the problem of loud sound in some positions and small sound in other positions. It increases the three-dimensional sense of the sound and improves the sound quality.

[0057] In addition, the sound component 14 in this embodiment is carried by the main board 11, and the panel 16 covers and hides the main board 11. Therefore, laying the sound outlet holes 161 on the entire surface of the panel 16 will not expose the internal structure. On the basis of protecting the internal structure of the speaker assembly 10, it meets the sound output requirements. Moreover, increasing the sound output range can also reduce the vibration problem and further improve the sound effect of the speaker assembly.

[0058] In short, through the setting of the speaker assembly 10 with sound output from the entire surface in this embodiment, on the basis of meeting the product structure assembly requirements, it can meet the sound output requirements of the large-size display device 20 from the entire surface, improving the market competitiveness of the product.

[0059] AsFigure 3 , Figure 4 , Figure 7 and Figure 8 As shown in Figure 3 , Figure 4 , Figure 7 and Figure 8 , as an implementation manner of this embodiment, it is disclosed that the shape of the main board 11 is strip-shaped, and first sunken steps 112 and second sunken steps 113 are provided on both sides of the main board 11 along the length direction; moreover, a plurality of clamping protrusions 114 are provided on the side wall of the main board 11 along the length direction, and a plurality of clamping grooves 115 are provided on the side wall of the main board 11 along the width direction; a limiting rib 162 that cooperates with the clamping groove 115 is provided on the panel 16; the edge of the panel 16 is bent towards the main board 11 to form a first flanging 163 and a second flanging 164, the first flanging 163 overlaps with the first sunken step 112, and the second flanging 164 overlaps with the second sunken step 113; a plurality of bayonet openings 165 are provided on both the first flanging 163 and the second flanging 164, and the bayonet openings 165 are used to snap into the clamping protrusions 114.

[0060] In this embodiment, the main board 11 and the panel 16 are fitted together. The first flanging 163 is placed on the first sunken step 112, and the second flanging 164 is placed on the second sunken step 113 to limit the panel 16, so that the panel 16 is kept stable along its own width direction; in addition, the clamping groove 115 and the limiting rib 162 are clamped to also limit the panel 16, so that the panel 16 is kept stable along its own length direction. That is to say, through the assembly of the panel 16 and the main board 11, the two are accurately aligned and kept stable. When the panel 16 and the main board 11 are assembled, the clamping protrusions 114 and the bayonet openings 165 can be quickly aligned and clamped through extrusion installation, so as to connect the panel 16 and the main board 11 into one body.

[0061] It can be seen that in this embodiment, the panel 16 and the main board 11 are connected into one body, which can increase the structural strength of the main board 11, make the supporting performance of the main board 11 better, and is beneficial to carrying the sound component 14 and convenient for moving and transporting.

[0062] In addition, after the panel 16 and the main board 11 are assembled, the first flanging 163 and the second flanging 164 wrap the main board 11, so that the space between the panel 16 and the main board 11 has good airtightness. First, it can protect the dust-proof net 15 and increase the stability of the dust-proof net 15; second, it can form a cavity for sound transmission. When sound waves enter this cavity from the support grille 111, they spread out and are transmitted from the front of the panel 16. The front of the panel 16 is provided with sound-emitting mesh holes 161 over the entire surface, so a sound-emitting effect over the entire surface can be formed, improving the sound quality.

[0063] Specifically, on the panel 16 disclosed in this embodiment, the ends of the limiting rib strips 162 can form a third flanging and a fourth flanging, thereby shielding the ends of the main board 11 and further protecting the main board 11. The first flanging 163, the second flanging 164, the third flanging and the fourth flanging enclose the strip-shaped main board 11, avoiding the problem of sound leakage from the side and reducing the entry of dust at the same time.

[0064] As Figure 8 shown, the area of the panel 16 disclosed in this embodiment facing the main board 11 is the sound transmission area, and sound outlet holes 161 are provided on the entire surface. The shape of the sound outlet holes 161 can be set as long strip-shaped, diamond-shaped or circular. By arranging a plurality of sound outlet holes 161 in an array, a grid-shaped mesh plate with a regular shape is formed, and the appearance is neat and beautiful. However, the mesh flat plate has the problem of insufficient structural strength and is prone to deformation. In this embodiment, by setting flangings such as the first flanging 163, the second flanging 164, the third flanging and the fourth flanging, the structural support at the edge of the panel 16 is increased, thereby increasing the strength of the overall structure, enabling the panel 16 to be connected to the main board 11 and maintaining stability, not being prone to deformation, and can be used for a long time.

[0065] Specifically, as another implementation manner of this embodiment, it is disclosed that the distance between two adjacent card slots 165 is 100 - 150 millimeters. The card slots 165 disclosed in this embodiment are integrally formed on the first flanging 163 or the second flanging 164. When the panel 16 and the main board 11 are assembled, the first flanging 163 is aligned with the first sinking step 112, and the second flanging 164 is aligned with the second sinking step 113. At this time, the card slot 165 extends towards the side wall of the main board 11 and is aligned with the card protrusion 114, thereby realizing snap connection and fixing the panel 16 on the main board 11.

[0066] Specifically, when the main board 11 is set to be strip-shaped, a plurality of card protrusions 114 are arranged along the length direction of the main board 11, and correspondingly, a plurality of card slots 165 are arranged on the panel 16, thereby realizing multi-point snap connection, increasing the connection points between the main board 11 and the panel 16, improving the connection strength, and increasing the connection stability.

[0067] In this embodiment, considering the actual processing complexity, the distance between two adjacent card slots 165 is set between 100 - 150 millimeters. If the distance between adjacent card slots 165 is too close, a lot of card slots 165 need to be set, increasing the processing difficulty and the installation difficulty; if the distance between adjacent card slots 165 is too far, the connection strength between the main board 11 and the panel 16 will be affected, increasing the risk of disassembly. Preferably, the distance between two adjacent card slots 165 in this embodiment is 120 millimeters.

[0068] In addition, it should be noted that the distance between two adjacent bayonets 165 disclosed in this embodiment can be any value between 100 and 150 millimeters or the range between any two values, such as 100 millimeters, 110 millimeters, 120 millimeters, 130 millimeters, 140 millimeters, 150 millimeters, etc.

[0069] Specifically, in another implementation manner of this embodiment, the limiting rib 162 is integrally formed with the panel 16, and 3 - 5 limiting ribs 162 can be provided on the side of the panel 16 along the width direction. Correspondingly, 3 - 5 card slots 115 are also provided on the main board 11, so as to increase the matching points and enhance the limiting effect.

[0070] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, as another implementation manner of this embodiment, a plurality of screw hole columns 116 are arranged on the main board 11 along the length direction. The first bracket 12 is provided with first screw through holes 121 corresponding to the screw hole columns 116, and the second bracket 13 is provided with second screw through holes 131 corresponding to the screw hole columns 116; both the first bracket 12 and the second bracket 13 are screwed to the main board 11 through screws.

[0071] In this embodiment, both the first bracket 12 and the second bracket 13 are connected to the main board 11 by screwing, which has high assembly efficiency, firm connection, and is beneficial for long - term use. Specifically, two or more first screw through holes 121 can be provided on the first bracket 12 to connect multiple screw hole columns 116, making the connection between the first bracket 12 and the main board 11 more firm and reducing the shaking or offset of the first bracket 12; similarly, two or more second screw through holes 131 can also be provided on the second bracket 13 to increase the connection strength between the second bracket 13 and the main board 11.

[0072] In this embodiment, connection columns can be provided on both the first bracket 12 and the second bracket 13, and a bushing can be provided on the sound component 14 to sleeved the connection columns, so as to realize the stable assembly of the sound component 14 with the first bracket 12 and the second bracket 13.

[0073] Again, as Figure 2 and Figure 3 shown, when the main board 11 disclosed in this embodiment is a strip - shaped main board 11, a plurality of support grids 111 can be formed by hollowing along the length direction of the strip - shaped main board 11. At the same time, a plurality of first brackets 12 and a plurality of second brackets 13 can be provided to assemble a plurality of sound components 14. By the way of multiple sound sources sounding simultaneously, the volume is increased, the sound effect is improved, so that the volume at both ends is more uniform when the panel 16 emits sound, the sound quality is more balanced, and the speaker effect is improved.

[0074] Specifically, as another implementation manner of this embodiment, it is disclosed that an adhesive layer is provided around the support grille 111 on the main board 11, and the adhesive layer is used to bond the dust-proof net 15. The support grille 111 disclosed in this embodiment functions to block and protect the sound component 14, and at the same time, the hollow holes on the support grille 111 can transmit sound. By setting the dust-proof net 15, dust can be blocked to prevent the dust in the air from floating to the back of the main board 11 through the support grille 111, avoiding dust accumulation on the sound component 14 or the control circuit board and affecting the use.

[0075] Specifically, the dust-proof net 15 is of a mesh structure and does not affect sound transmission. Through an adhesive layer such as double-sided tape or solid glue, it can be quickly attached to the main board 11, with convenient operation and firm connection.

[0076] Specifically, as another implementation manner of this embodiment, it is disclosed that the size of the dust-proof net 15 is the same as that of the main board 11. That is to say, the dust-proof net 15 is laid flat on the front of the main board 11 to completely cover the main board 11. Such a setting facilitates the attachment operation and can ensure complete shielding of the support grille 111, enhancing the dust-proof effect.

[0077] Specifically, as another implementation manner of this embodiment, it is disclosed that the dust-proof net 15 is a nylon net. In this embodiment, a nylon net with low cost, good dust-proof effect, and long service life can be used as the dust-proof net 15. Utilizing the dyeable characteristic of the nylon material, preferably, a black nylon net can be used to increase light absorption. When observing from outside the panel 16, the internal structure of the speaker assembly 10 cannot be seen, increasing the concealment and aesthetic effect.

[0078] Specifically, as another implementation manner of this embodiment, it is disclosed that the mesh number of the dust-proof net 15 is 400 - 800 meshes. If the mesh number of the dust-proof net 15 disclosed in this embodiment is too high, it may affect the sound transmission, while if the mesh number of the dust-proof net 15 is too low, the dust-proof effect will be insufficient. Therefore, the mesh number of the dust-proof net 15 is set to 400 - 800 meshes to balance the dust-proof effect and the sound transmission function.

[0079] It should be noted that the mesh number of the dust-proof net 15 disclosed in this embodiment can be any value between 400 - 800 meshes or the range between any two values, such as 400 meshes, 500 meshes, 600 meshes, 700 meshes, 750 meshes, 800 meshes, etc. Preferably, the mesh number of the dust-proof net 15 is set to 600 meshes to balance the cost, dust-proof effect, and sound transmission effect of the dust-proof net 15.
