[0024] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] like Figure 1 As shown, a surface acoustic source auxiliary sound system includes a frame 1, a vibrating sound-generating plate 2, a driver 3, a sound insulation plate 4, and a back plate 5 disposed on the rear side of the frame 1. Two drivers 3 are provided, each disposed on the vibrating sound-generating plate 2, for driving the vibrating sound-generating plate 2 to generate vibration and sound. The vibrating sound-generating plate 2 and the sound insulation plate 4 are disposed within the frame 1, with the sound insulation plate 4 positioned between the vibrating sound-generating plate 2 and the back plate 5. A first damping element 6 is disposed between the vibrating sound-generating plate 2 and the frame 1, and a second damping element 7 is disposed between the sound insulation plate 4 and the frame 1.

[0026] The working principle of the surface sound source auxiliary sound system of this application is as follows: When the driver 3 receives an audio signal, the driver 3 drives the vibrating sound-generating plate 2 to vibrate. The vibrating sound-generating plate 2 converts electrical energy into mechanical energy, thereby generating sound, which propagates forward. However, since the vibrating sound-generating plate 2 also guides the air in the sealed space inside the frame 1 to vibrate when vibrating to generate sound, the sound is easily diffused to the back. This not only leads to the waste of sound energy, but also reduces the sound pressure level in the direction of sound propagation, affecting the sound quality and sound propagation effect. Therefore, this application solves the problem of sound diffusion and leakage to the back by setting a sound insulation plate 4 between the vibrating sound-generating plate 2 and the back plate 5. The sound insulation plate 4 plays the role of isolating and absorbing sound, blocking the path of vibration energy to be transmitted to the rear back plate 5 through the air, forming a sound barrier structure for the back, thereby effectively solving the problem of sound diffusion and leakage to the back. Meanwhile, to reduce vibration transmission, a first damping component 6 is provided between the vibrating sound-generating plate 2 and the frame 1, and a second damping component 7 is provided between the sound insulation plate 4 and the frame 1. Specifically, the vibrating sound-generating plate 2 and the sound insulation plate 4 are respectively provided with connecting holes, and the connecting holes are respectively installed and fixed to the frame 1 by bolts. The damping component adopts a vibration-damping silicone sleeve, which is inserted into each connecting hole, and the bolts are inserted into the vibration-damping silicone sleeve. This can reduce the impact of the vibration generated by the vibrating sound-generating plate 2 and the sound insulation plate 4 on the frame 1 during operation, avoid noise caused by vibration, and at the same time ensure the relative stability between the components and improve the overall performance of the system.

[0027] The beneficial effects of the surface sound source auxiliary sound system of this application are as follows: through reasonable structural design, it effectively blocks and absorbs sound that diffuses to the back, reduces the waste of sound energy, improves the propagation efficiency and directionality of sound, and improves the sound quality and sound propagation effect.

[0028] In the specific implementation process of this application, see [link / reference]. Figure 1 A first sound-absorbing layer 41 is provided on the side of the sound insulation panel 4 facing the vibrating sound-generating panel 2. A second sound-absorbing layer 51 is provided on the side of the back panel 5 facing the sound insulation panel 4. The sound-absorbing layers can absorb sound, further reduce the energy of sound propagating to the back, and enhance the sound insulation effect.

[0029] In the specific implementation process of this application, see [link / reference]. Figures 1 to 3 A first waterproof foam ring 21 is provided between the vibrating sound-generating plate 2 and the frame 1. A second waterproof foam ring 42 is provided between the sound insulation plate 4 and the frame 1. After the vibrating sound-generating plate 2 and the sound insulation plate 4 are installed and fixed to the frame 1, the thickness of the waterproof foam ring is compressed and reduced by half, which can effectively play the role of sealing, waterproofing and vibration prevention, effectively blocking the physical transmission of vibration energy to the surface sound source frame 1, and can also seal the internal space of the frame 1 to a certain extent to prevent sound leakage.

[0030] In the specific implementation process of this application, see [link / reference]. Figure 1 and Figure 4The surface sound source auxiliary sound system also includes a panel 8 located on the front side of the frame 1. The panel 8 is made of waterproof decorative board, which can protect the internal structure of the system, modify and guide the sound emitted from the front to a certain extent, and also enhance the aesthetic appearance.

[0031] In the specific implementation process of this application, see [link / reference]. Figure 4 The surface sound source auxiliary sound system also includes a bracket 9, on which the frame 1 is mounted. The bracket 9 raises the height of the frame 1 and its internal components, making it higher than the height of the crowd, thus avoiding the problem of sound attenuation in the middle and far from the crowd caused by the nearby crowd blocking the sound in densely populated places.

[0032] Furthermore, the tilt angle between the frame 1 and the support 9 is adjustable, ranging from 0 to 15 degrees. By adjusting the tilt angle between the frame 1 and the support 9, the direction of sound propagation can be adjusted according to the actual usage scenario and needs, effectively controlling the center point of sound radiation within the sound field range, improving the flexibility and adaptability of sound propagation, and effectively preventing sound leakage.

[0033] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. The scope of protection of the present utility model should be determined by the scope of the claims. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
