Abstract
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.
Claims8
An in-ear earphone, comprising:
- a housing;
- an electro-acoustic transducer disposed in the housing;
- a sound tube extended outward from the housing, the sound tube having a first channel connected with the housing for receiving an acoustic wave generated by the transducer and a second channel connected with the first channel;
- and
- an earplug disposed on the sound tube for being inserted into an external auditory canal of a user;
- wherein, a cross-section area of the second channel is different from a cross-section area of the first channel for reducing the acoustic wave generated by the electro-acoustic transducer and delivering the acoustic wave outward.
