Furthermore, the protection pad is in annular arrangement, and the protection pad is sleeved outside the flange.
Further, the inner layer is arranged based on a sponge, the middle layer is arranged based on a sound insulation felt, and the outer layer is arranged based on polyurethane foam.
Further, the protruding blocks are evenly distributed on the back of the protection pad, the protruding blocks are formed by filling sponge in the outer skin of the protection pad, the protruding blocks correspond to the inserting holes one by one, and the opening diameter of each inserting hole is smaller than the inner diameter of each inserting hole.
Further, the flange is formed by gluing the unfilled pad skin.
Compared with the prior art, the utility model provides the multilayer noise insulation earmuff, which has the following beneficial effects:
This multilayer noise insulation earmuff, through setting up inlayer, middle level and skin, encircle in the ear outside when wearing, form three sound insulation structure, increase the separation to the inside and outside sound of earphone, inlayer, middle level and outer setting are based on different sound insulation material simultaneously, and the three is different to different kind sound separation effect, and the scope of sound separation has improved the sound insulation effect of earphone earmuff.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
In the figure: 1. an earphone body; 11. a flange; 12. a sound producing hole; 13. a clamping groove; 14. a jack; 2. a protective pad; 21. a bump; 22. a rib; 23. an inner layer; 24. a middle layer; 25. an outer layer.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the utility model discloses a multi-layer noise-isolation earmuff, which comprises an earphone body 1, wherein a protection pad 2 is arranged on the side surface of the earphone body 1; the side face of the earphone body 1 is provided with a flange 11, the inner side of the flange 11 is provided with a sounding hole 12, the outer side of the flange 11 is provided with a clamping groove 13, and the side face of the earphone body 1 is provided with an inserting hole 14; the back of the protection pad 2 is provided with a bump 21, the inner side of the protection pad 2 is provided with a convex rib 22, and the protection pad 2 comprises an inner layer 23, a middle layer 24 and an outer layer 25.
Specifically, the protection pad 2 is in a ring shape, and the protection pad 2 is sleeved outside the flange 11.
In this embodiment, the protection pad 2 is sleeved outside the flange 11, and covers the outside of the ear when the earphone is worn, so as to form a relatively sealed space, and achieve a certain sound insulation effect.
Specifically, the inner layer 23 is arranged based on a sponge, the middle layer 24 is arranged based on a sound insulation felt, the outer layer 25 is arranged based on polyurethane foam plastic, and the inner layer 23, the middle layer 24 and the outer layer 25 are nested one by one.
