[0037] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0038] The dimensions and specifications listed in this article are all for this implementation case, and the specific product dimensions can be set according to actual conditions.

[0039] Now combined Figures 1 to 12 As shown, an earmuff structure of the present invention is described, including an earmuff unit 10, wherein the earmuff unit 10 has a cover plate 11, the center of the cover plate 11 is penetrated by an earmuff hole 111 and the surface is penetrated by a plurality of through holes 112, and a sound insulation material 101 made of foam sponge is integrally combined with the two side surfaces of the cover plate 11 and the surface of the earmuff hole 111 through the through holes 112.

[0040] With the above structure, when the user puts the ear into the earmuff hole 111, the sound insulation material 101 is integrated with both side surfaces of the cover plate 11 and the surface of the earmuff hole 111 through the through hole 112, thereby ensuring that the ear of the user will not be scratched by the cover plate 11 when wearing the earmuff unit 10.

[0041] The earmuff unit 10 of the earmuff structure of the present invention further comprises an outer cover 12 , and the cover plate 11 is assembled and fixed with the outer cover 12 , so that the earmuff unit 10 can be effectively isolated when the ear of the user is wearing it.

[0042] The inner side of the outer cover 12 of the earmuff structure of the present invention is also integrated with the sound insulation material 101 , so that the earmuff unit 10 can achieve a sound insulation effect more effectively.

[0043] See also Figures 3 to 9 As shown, the cover plate 11 and the outer cover 12 of the earmuff structure of the present invention are respectively placed in a mold 20 together with at least one foaming material 102. The mold 20 has a mold chamber 21. The cover plate 11 or the outer cover 12 and the foaming material 102 are placed in the mold chamber 21. The foaming material 102 is foamed with the mold chamber 21 as the boundary to form the sound insulation material 101 and is integrated with the cover plate 11 or the outer cover 12. Then, the cover plate 11 and the outer cover 12 are combined to complete the earmuff unit 10. The sound insulation material 101 is integrated with the cover plate 11 and the outer cover 12, so a lot of time can be saved during manufacturing and combining. When preparing in batches, the sound insulation material 101 can be integrated with the cover plate 11 and the outer cover 12 first, and the operator only needs to combine and fix the cover plate 11 and the outer cover 12, which is easy to manufacture and produce, and can save time and improve manufacturing efficiency.

[0044] See also Figures 10 to 12 As shown, the cover plate 11 of the earmuff structure of the present invention is first assembled with the outer cover 12 and then put into a mold 20 together with at least one foaming material 102. The mold 20 has a mold chamber 21. The cover plate 11 or the outer cover 12 and the foaming material 102 are in the mold chamber 21. The foaming material 102 is foamed with the mold chamber 21 as the boundary to form the sound insulation material 101 and is integrated with the cover plate 11 and the outer cover 12 to complete the earmuff unit 10. The sound insulation material 101 is integrated with the cover plate 11 and the outer cover 12 so that the two are inseparable, the sound insulation effect is enhanced, and the protection is more comprehensive. The existence of the through hole 112 can help the foaming material 102 pass through the through hole 112 during the foaming process to form the sound insulation material 101, so that the sound insulation material 101 can be integrated with the two side surfaces of the cover plate 11 and the surface of the earmuff hole 111 to increase the covering area.
