Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment 1:

[0026] Figure 1 It shows a schematic structural diagram of the sound - emitting screen in the embodiment of the present utility model. The sound - emitting screen includes: a sound - emitting screen main body 1, a plurality of sound - emitting units 3 arranged on the back of the sound - emitting screen main body 1, and one or more isolation strips 2 located in the middle region of the sound - emitting screen main body 1. Two or more sound - emitting units 3 are symmetrically distributed on both sides of the sound - emitting screen main body 1. The isolation strip 2 is located between the symmetrically distributed multiple sound - emitting units 3. Based on the isolation strip 2, the isolation degree of the left and right channels of the sound - emitting screen can be improved, and the discrimination rate of the left and right channels of the sound - emitting screen can be effectively improved, thereby improving the sound effect of the sound - emitting screen.

[0027] Specifically, the sound - emitting unit 3 includes a box body and a speaker arranged in the box body. The front side of the box body is attached to the back of the sound - emitting screen, and the sound - emitting surface of the speaker is attached to the front side of the box body. The box body can be fixed to the back of the sound - emitting screen main body 1 based on glue. When the speaker inside the box body works, it can drive the sound - emitting screen main body 1 to vibrate through audio vibration, so that the sound - emitting screen main body 1 drives the air in the external environment to vibrate, realizing the transmission of sound.

[0028] Specifically, a density board is pasted in the middle region of the sound - emitting screen, and the isolation strip 2 is formed based on the density board. By setting the density board, the mass density in the middle region of the sound - emitting screen is increased, and the vibration in the middle region of the sound - emitting screen is reduced, thereby improving the isolation degree of the left and right channels of the sound - emitting screen; and / or a slot is provided in the middle region of the sound - emitting screen, and the isolation strip 2 is formed based on the slot. Based on the slot structure, the structural rigidity in the middle region of the sound - emitting screen can be reduced, making it difficult for the vibrations of the left and right parts of the sound - emitting screen to spread, improving the discrimination degree of the left and right channels of the sound - emitting screen, and thus improving the sound effect of the sound - emitting screen.

[0029] Further, a plurality of the isolation strips 2 may be provided in the middle region of the sound - emitting screen main body 1, and the plurality of the isolation strips 2 are arranged evenly, so that the vibration propagation in the middle region of the sound - emitting screen is weak, and the distance between the left and right sound channels of the sound - emitting screen is increased, thereby improving the sound - emitting effect of the sound - emitting screen.

[0030] Figure 2 FIG. 4 shows a schematic structural view of the isolation strip 2 in an embodiment of the present invention. Specifically, the sound - emitting screen main body 1 is fixed to the wall based on a magnetic attraction method. In this embodiment, the density board forms the isolation strip 2, and when the sound - emitting screen main body 1 is fixed to the wall based on the magnetic attraction method, a magnet sheet 4 is pasted on the density board, and an iron sheet 5 is provided on the wall, and the magnet sheet 4 is correspondingly attached to the iron sheet 5.

[0031] A density board is pasted in the middle region of the back of the sound - emitting screen main body 1, and a magnet sheet 4 is fixedly pasted on the back surface of the density board. In this embodiment, the thickness of the density board is 18 mm, and the thickness of the magnet sheet 4 is 1 mm. Fixing the magnet sheet 4 on the density board makes the sound - emitting screen main body 1 have a magnetic attraction effect, and the magnet sheet 4 is provided on the isolation strip 2 formed by the density board, which can simplify the structural design of the back of the sound - emitting screen main body 1 and improve the convenience of the magnetic - attraction installation structure of the sound - emitting screen.

[0032] Further, another density board is fixed on the wall, and the thickness of the density board can be set to 18 mm. An iron sheet 5 is adhesively fixed on the front surface of the density board through glue. By providing density boards on the back of the sound - emitting screen main body 1 and on the wall, the structural rigidity of the connection structure between the sound - emitting screen main body 1 and the wall can be improved, and the probability that the connection structure between the sound - emitting screen main body 1 and the wall vibrates during the operation of the sound - emitting screen can be reduced, thereby ensuring the accuracy of the sound - emitting direction of the sound - emitting screen.

[0033] Further, the width of the iron sheet 5 is 1.5 times the width of the magnet sheet 4, which improves the fault tolerance of the magnetic - attraction cooperation between the magnet sheet 4 on the isolation strip 2 on the back of the sound - emitting screen main body 1 and the iron sheet 5 on the wall, so as to magnetically - attract and fix the sound - emitting screen main body 1 on the wall.

[0034] Specifically, when the density board forms the isolation strip 2, the thickness of the isolation strip 2 is d1, and the value range of d1 is: 5 mm ≤ d1 ≤ d s where d s is the thickness of the sound - emitting unit 3. When the sound - emitting screen is installed on the wall, a preset interval is formed between the sound - emitting unit 3 and the wall, which avoids the contact between the sound - emitting unit 3 and the wall and ensures the sound - emitting effect of the sound - emitting unit 3.

[0035] Set the thickness of the isolation strip 2 to be less than the thickness of the sound - generating unit 3, and ensure that the thickness of the isolation strip 2 is less than the distance between the sound - generating screen main body 1 and the wall after installation, so as to avoid interference of the isolation strip 2 with the installation of the sound - generating screen main body 1.

[0036] Specifically, when the isolation strip 2 is formed by grooving, the thickness of the isolation strip 2 is d1′, and the value range of d1′ is: 1mm ≤ d1′ ≤ d L , where d L is the thickness of the sound - generating screen main body 1. When the isolation strip 2 is set by grooving, by setting the thickness of the isolation strip 2 to be greater than half of the thickness of the sound - generating screen main body 1, the thickness of the isolation strip 2 can meet the requirements for improving the sound effect of the sound - generating screen.

[0037] Specifically, the height of the isolation strip 2 is h1, and the value range of h1 is: 1mm ≤ h1 ≤ h L , where h L is the height of the sound - generating screen main body 1. The width of the isolation strip 2 is w1, and the value range of w1 is: w s ≤ w1 ≤ w L / 3, where w s is the width of the sound - generating unit 3, and w L is the width of the sound - generating screen main body 1. Setting the isolation strip 2 with a certain thickness, width and height enables the isolation strip 2 to meet the sound - effect improvement effect of the sound - generating screen, and at the same time improves the appearance ornamental value of the sound - generating screen main body 1.

[0038] Specifically, please refer to Figure 2 , a frame 6 can be provided around the sound - generating screen main body 1, and a sealing strip 61 is provided on the side of the frame 6 in contact with the wall. When the sound - generating screen main body 1 is fixed to the wall, the sealing strip 61 of the frame 6 abuts against the wall, which can improve the sealing between the sound - generating screen main body 1 and the wall and enhance the reliability of the installation and use of the sound - generating screen main body 1.

[0039] Furthermore, due to the magnetic attraction between the iron sheet 5 on the wall and the magnet sheet 4 on the back of the isolation strip 2 of the sound - generating screen main body 1, the sealing strip 61 of the frame 6 can be compressed and deformed, making the cavity space on the back of the sound - generating screen airtight.

[0040] An embodiment of the present utility model provides a sound - generating screen. By providing an isolation strip 2 in the middle area of the sound - generating screen main body 1, the sound - generating units 3 in the left and right areas on the back of the sound - generating screen main body 1 are isolated based on the isolation strip 2, so as to improve the isolation degree of the left and right channels of the sound - generating screen, thereby improving the discrimination degree of the left and right channels of the sound - generating screen and effectively improving the sound effect of the sound - generating screen.

A first fitting board with a hook 21 structure is pasted and fixed on the isolation strip 2. Another density board is pasted and fixed on the wall, and a second fitting board with a hook groove is pasted and fixed on the density board. The sound - emitting screen main body 1 is hung on the second fitting board on the wall based on the hook 21 of the first fitting board, so that the hook 21 and the hook groove are in one - to - one correspondence and cooperation. Based on the self - weight of the sound - emitting screen main body 1, the tight connection between the first fitting board and the second fitting board can be realized.
