Claim:
An in-ear earphone, comprising: a shell including an upper shell and a lower shell cooperating with the upper shell to define a resonance space therebetween; a loudspeaker assembled in the resonance space of the shell; a plurality of damping objects made of different elastic and compressible materials for achieving different sound effects; a group of first adjusting elements capable of being replaceablely assembled to a bottom of the lower shell for receiving external sound signals for the loudspeaker, each of the first adjusting elements defining a receiving fillister penetrating through a top thereof, a sound hole being opened in a substantial middle of a bottom of the first adjusting element and connected with the receiving fillister, each of the first adjusting elements having one damping object disposed in the receiving fillister and further disposed between the sound hole and the resonance space; and a group of second adjusting elements capable of being replaceablely assembled to a top of the upper shell for transmitting the sound signals out, each of the second adjusting elements defining a receiving cavity at a top end thereof for receiving one of the damping objects therein, the damping object further facing to the resonance space.
