Particularly, described main part comprises the first main part and the second main part, described through hole is opened in described first main part, a groove corresponding with described through hole is offered outside described second main part, be convenient to outside air and enter described through hole by described groove, avoid described earplug and described duct too to seal, air is difficult to arrive described through hole, ensure that earplug front and back end air pressure equilibrium of forces.
Particularly, the external diameter of described second main part slightly larger than or equal earhole aperture, the external diameter of described first main part is less than the external diameter of described second main part, conveniently described earplug is filled in duct, and the difference in size between described first main part and described second main part, when earplug also can be avoided to enter duct, the pain or loss that excessive instantaneous pressure causes is produced to eardrum, make process of wearing more comfortable.
Particularly, the aperture, front hole of described cavity portion is greater than the metapore aperture of described cavity portion, makes sound be delivered to eardrum to a greater extent.
Particularly, described earplug is one-body molded, and described soft elastic material is rubber or silica gel.
Preferably, described main part is cylindrical, is convenient to machine-shaping.
Preferably, described through hole is set to 2, and described groove is set to 1, and this setup can make earplug front and back end air pressure reach balance sooner, wears more comfortable, and can reduce acoustical leakage to greatest extent.
Preferably, multiple described through hole is symmetricly set in outside described first main part, and multiple described groove is symmetricly set in outside described second main part.
Preferably, described umbrella spoke portion thickness is 0.2-0.4mm.
Preferably, the aperture of described through hole is 1.2-1.8mm.
Preferably, the width of described groove is 0.8-1.2mm, and the degree of depth is 1.0-1.3mm.
