[0004] This utility model is achieved through the following technical solution:

The sound-absorbing crystal bubble panel body includes an inner layer and a sound-absorbing and noise-reducing reinforcing fiber layer. Both sides of the inner layer are coated with the sound-absorbing and noise-reducing reinforcing fiber layer. The inner layer includes a honeycomb keel plate layer and a first tensile steel wire, a second tensile steel wire, and a third tensile steel wire arranged in the honeycomb keel plate layer.

[0007] Furthermore, the depth of the first cable slot is half the thickness of the inner layer, the depth of the second cable slot is one-third the thickness of the inner layer, the opening of the third cable slot is on a different side from the opening of the second cable slot, and the depth of the third cable slot is one-third the thickness of the inner layer.

[0008] Furthermore, each of the first, second, and third tensile steel wires has an integrally formed pair of wire knots in each honeycomb cavity of the honeycomb keel plate layer, and the wire knots abut against the honeycomb cavity wall of the honeycomb keel plate layer.

[0009] Furthermore, the sound-absorbing and noise-reducing reinforcing fiber layer is constructed by weaving glass fiber threads as warp and nylon threads as weft, and plastic particles are evenly laid on the bonding surface between the sound-absorbing and noise-reducing reinforcing fiber layer and the inner layer.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a honeycomb keel plate layer composed of a honeycomb plate-shaped keel support made of gel material to give the sound-absorbing crystal bubble panel body good compressive support performance. At the same time, the honeycomb cavity of the honeycomb keel plate layer is filled with a sound-absorbing crystal bubble filler composed of open-cell microbubble sound-absorbing particles to ensure the sound absorption performance of the sound-absorbing crystal bubble panel body. The two sides of the inner layer are composited with a sound-absorbing and noise-reducing reinforcing fiber layer woven from glass fiber filaments and nylon filaments. Plastic particles are evenly laid on the bonding surface between the sound-absorbing and noise-reducing reinforcing fiber layer and the inner layer to ensure the wear resistance and tensile strength of the surface of the sound-absorbing crystal bubble panel body, while further improving the sound absorption performance of the sound-absorbing crystal bubble panel body.

[0012] 2. In this utility model, the first tensile steel wire, the second tensile steel wire, and the third tensile steel wire are arranged in three directions along the honeycomb cavity in the honeycomb keel board layer to enhance the fracture resistance of the inner layer under tensile or shear force. The structure is stable and is not affected by the destruction of the stable structure due to the size cutting of the sound-absorbing crystal bubble board body.
