[0040] like Figure 1-Figure 8As shown, the present invention provides a display device, including a display screen 1 and a frame 2 wrapped around the periphery of the display screen 1, a speaker 3 and a touch frame 4 are arranged in the frame 2, and the touch frame 4 includes a first section 41 and a second section 42 which are electrically connected, the first section 41 is connected to the frame 2, and the second section 42 is connected to the speaker 3. By setting the touch frame 4 as a split structure, the first section 41 is directly mounted on the frame 2, and the second section 42 which interferes with the speaker 3 is directly mounted on the speaker 3, and the first section 41 and the second section 42 are spliced ​​and electrically connected to form a whole touch frame 4, while ensuring the touch function, the width of the frame 2 is effectively reduced, and the speaker 3 can be arranged on the left frame and / or the right frame, while ensuring the aesthetics of the whole machine, the sound effect and sense of presence of the speaker 3 are improved, and the sound performance of the whole machine is improved.

[0041] In this embodiment, speakers 3 are provided on both the left and right frames, which effectively improve the sound effect of the speakers 3. Correspondingly, the touch frames 4 provided on the left and right frames adopt a split structure, and multiple sections of touch frames 4 are spliced ​​into a whole touch frame 4. The touch frames 4 provided on the upper and lower frames can be an integrated long strip structure.

[0042] Preferably, in addition to the speaker 3 being arranged on the lower frame, the middle of the left frame and the right frame are also provided with speakers 3, so that the overall sense of presence of the sound emitted by the whole machine is stronger. For the left frame and the right frame, the two first sections 41 are respectively arranged on the upper and lower sides of the second section 42 on the speaker 3. Of course, in other embodiments, the speaker 3 can also be arranged at the end of the frame 2, or multiple speakers 3 can be arranged on the same frame 2.

[0043] In one embodiment, a first pin 411 is provided on the first section 41, and a second pin 421 is correspondingly provided on the second section 42. The first pin 411 and the second pin 421 are plugged together to achieve a stable electrical connection between the first section 41 and the second section 42, with a simple structure and convenient installation. In other embodiments, the first section 41 and the second section 42 can also be electrically connected by means of a connecting wire. For example, a first electrical interface is provided on the first section 41, and a second electrical interface is provided on the second section 42, and electrical plugs plugged into the first electrical interface and the second electrical interface are provided at both ends of the connecting wire.

[0044] Exemplarily, the inner wall of the frame 2 is provided with two opposite card slots, and the opposite ends of the first section 41 are respectively inserted into the corresponding card slots to achieve installation limitation of the first section 41 in the frame 2. Preferably, the two card slots can be spaced and arranged oppositely along the thickness direction of the frame 2 to achieve limitation of the first section 41 along the front and rear direction of the display device. In other embodiments, the first fastener passes through the touch PCBA of the first section 41 and is threadedly connected to the frame 2 to achieve installation of the first section 41 on the frame 2. The threaded connection has high strength, is easy to disassemble and assemble, and has low cost. The first fastener can be a screw.

[0045] Optionally, the second fastener passes through the PCBA of the second section 42 and is threadedly connected to the speaker 3 to achieve installation of the second section 42 on the speaker 3. The threaded connection has high strength, is easy to assemble and disassemble, and has low cost. The second fastener may be a screw.

[0046] Furthermore, the display device further includes a back plate 5 , which is spaced apart on the back side of the display screen 1 and connected to the frame 2 .

[0047] The back side of the frame 2 is provided with a first opening 21 communicating with the inner cavity thereof, and the speaker 3 includes a sound outlet 31 and a connecting portion 32 connected thereto, the sound outlet 31 extends from the first opening 21 into the frame 2, and the connecting portion 32 is pressed against the back plate 5, so that the speaker 3 is installed on the frame 2. The second section 42 is connected to the sound outlet 31. Specifically, the second section 42 is connected to a side of the sound outlet 31 close to the center of the display device to ensure normal transmission or reception of signals.

[0048] In this embodiment, the first opening 21 passes through the front and rear sides of the frame 2, and the sound outlet 311 of the sound outlet portion 31 faces the front side of the frame 2. The sound emitted by the speaker 3 is transmitted to the front side of the display device, and the sound effect is better. The front side of the sound outlet portion 31 is preferably flush with the front side of the frame 2, so that the front side of the frame 2 is a plane, which improves the aesthetics of the display device. The cross-sectional area of ​​the sound outlet portion 31 is preferably the same as the cross-sectional size of the first opening 21. At the same time, a sealing member such as foam is provided between the speaker 3 and the frame 2 to prevent impurities such as dust or water vapor from entering the inner cavity of the frame 2 through the gap between the sound outlet portion 31 and the inner wall of the first opening 21.

[0049] In other embodiments, the first opening 21 may not pass through the front side of the frame 2. In this case, a speaker 3 hole is opened on the front side of the frame 2 to be opposite to the sound hole 311 of the sound outlet portion 31. This can effectively prevent external impurities such as dust or water vapor from entering the inner cavity of the frame 2, while improving the overall strength of the frame 2.

[0050] See also Figure 6-Figure 8 , a connecting arm 33 is convexly provided on the connecting portion 32, and a shock absorber 6 is provided on the connecting arm 33. Specifically, the speaker 3 extends along the length direction of the frame 2, and the connecting arms 33 are provided at both ends of the length direction of the speaker 3. A connecting hole is provided on the connecting arm 33, and the end of the connecting hole away from the speaker 3 has a second opening. The outer walls of the upper and lower ends of the shock absorber 6 have annular protrusions 61. The middle part of the shock absorber 6 is inserted into the connecting hole of the fixed arm through the second opening under compression. The diameter of the annular protrusion 61 is larger than the diameter of the connecting hole of the connecting arm 33, and the annular protrusion 61 can prevent the shock absorber 6 from falling off from the connecting arm 33.

[0051] The shock absorber 6 is provided with a mounting hole 62, and the shock absorber 6 is sleeved outside the connection hole column 51 through the mounting hole 62. The third fastener 7 is threadedly connected to the connection hole column 51 and presses the shock absorber 6, so that the speaker 3 is installed and fixed on the back plate 5 through the shock absorber 6. The shock absorber 6 can reduce the sound of the speaker 3 and transmit its own vibration to the whole machine, avoiding the internal emission resonance of the whole machine, and ensuring the normal use of the whole machine. The third fastener 7 is preferably a screw, which is easy to install.

[0052] The shock absorbing member 6 is preferably made of a material having a certain elasticity and hardness, such as silicone, to achieve a stable connection between the speaker 3, the frame 2 and the back panel 5 while absorbing the shock.

[0053] See also Figure 3 and Figure 5 In other embodiments, the display device may further include a speaker cover 8, which is connected to the back panel 5. The speaker cover 8 covers and presses the speaker 3 to fix the speaker 3 on the frame 2. At the same time, the speaker cover 8 protects the speaker 3.
