[0003] In addition, with the advancement of materials science, some new lightweight sound insulation materials such as fiber-reinforced composites and polymer foam materials have gradually emerged, but they still face problems such as poor sound insulation and poor stability in practical applications.

[0004] Traditional sound insulation structures often have problems such as poor sound insulation effect, complex structure, and high cost. To this end, we provide a new type of sound insulation structure. Utility Model Content

[0005] The technical problem solved by the utility model is that the traditional sound insulation structure often has the problems of poor sound insulation effect, complex structure and high cost.

The plurality of sound absorbing shells are arranged in a frustum shape. A first sound absorbing hole and a second sound absorbing hole are arranged in the plurality of sound absorbing shells.

[0008] A further technical improvement of the utility model is that: the first sound absorbing hole is arranged in a cylindrical shape, and the first sound absorbing hole is located on a side of the sound absorbing shell away from the fixed layer.

[0009] A further technical improvement of the utility model is that: the second sound absorbing hole is arranged in a cone shape, the second sound absorbing hole is located on a side close to the fixed layer, a wide bottom surface and a thin bottom surface are respectively arranged on both sides of the second sound absorbing hole, and the wide bottom surface of the second sound absorbing hole is connected to the first sound absorbing hole.

[0010] A further technical improvement of the utility model is that a reinforcement sleeve is provided on the outside of the sound absorbing shell, the reinforcement sleeve is also arranged in a cone shape, and a reinforcement block is provided on the reinforcement sleeve, and the reinforcement block is located at a position of the reinforcement sleeve close to the thin bottom surface of the second sound absorbing hole.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

After that, the sound reaches the multiple sound-absorbing shells, and the cylindrical first sound-absorbing holes thereon can transmit the sound generated by the sound source.

The structure is simple and the use cost is reduced.
