摘要： An in-ear earphone includes a housing, a transducer, a sound tube and an earplug. The transducer is disposed in the housing. The sound tube is extended outward from the housing. The sound tube has a first channel connected with the housing for receiving the acoustic wave generated by the transducer, and a second channel connected with first channel and having a cross-section area different from the first channel. The earplug is disposed on the sound tube to be inserted into the ear channel of a user so as to reduce the frequency response of the acoustic wave which is delivered to the ear cannel of the user.
