Abstract: An earphone is disclosed. The earphone comprises an external auditory meatus insertion member, a casing and a driver unit. The external auditory meatus insertion member has a part which is insertable into an external auditory meatus. The external auditory meatus insertion member is detachable from the casing. The driver unit is disposed within the casing to generate sounds. The the external auditory meatus insertion member further includes an elastically deformable soft insertion member and a highly rigid hard insertion member.

Abstract: An ear pad is made of a deformable material and mounted on an earphone, at least a tip of which is insertable into an ear. The ear pad comprises a cylindrical body portion and an elastically deformable portion. The cylindrical body portion has a sound guide hole formed therein, being adapted to cause a sound to impinge on the ear. The deformable portion is connected to a tip of the body portion and spreads from the tip toward a rear end of the body portion, and includes a plurality of slit-shaped openings radially extending therefrom. The body portion includes grooves axially extending therefrom, corresponding to the openings in the outer peripheral surface of the body portion. Each opening overlaps with a corresponding groove in cases where the elastically deformable portion is deformed and pressed against the outer peripheral surface of the body portion.
