| titleOfInvention | Soundproof earphone |
| abstract | The utility model discloses a soundproof earphone. The soundproof earphone comprises an earphone main body and a supporting seat; the earphone main body is integrally formed by using silica gel and comprises a head part and a body part; the head part is spherical; the body part is cylindrical; the upper end of the body part is connected with the head part; the lower end of the body part is fixed on the supporting seat; a concave arc transition surface is formed in the middle of the body part; the earphone main body has a middle structure, and a ventilation hole path is formed in the earphone main body; and a through hole which is communicated with the ventilation hole path is formed on a foundation. Compared with the conventional common soundproof earphone, the soundproof earphone has the advantages that the small ventilation hole path is formed in the earphone main body, so that the pressure difference between the interiors of ears and the external atmospheric air is reduced, the speed that external air flows into ear cavities can be reduced, a user does not feel pressed and painful in the ears after continuously using the soundproof earphone for a long time, the pressure which is increased along with the increasing of the height in the ears is balanced, and the nausea caused when an airplane takes off and lands can be effectively avoided. |
