| titleOfInvention | Sound-insulation earmuff |
| abstract | The utility model discloses a sound-proof earmuff, which comprises two earmuffs with symmetrical structures; the same earmuff comprises a cover body, earplugs, an ear-winding hook and a connecting piece; the cover body can cover the ears of the human body; the earplug is provided with a fixed section, a deformation section and an ear-entering section which are connected in sequence; the fixed section is in a linear section shape, and the end part of the fixed section is fixed on the inner surface of the cover body; the deformation section is made of deformable materials and can deform when being subjected to external stress; the ear entering section is in a curve section shape and is matched with the shape of the inside of the auditory canal; the upper end of the ear-winding hook is detachably connected to the top end of the inner side of the cover body through a connecting piece, and the ear-winding hook and the cover body are relatively fixed during connection; the ear-surrounding hook is hung on the ear, the cover body covers the outside of the ear, and the deformation section and the ear-entering section of the earplug are both inserted into the ear canal. The utility model has the advantages of good sound insulation effect, stable and convenient wearing, etc. |
