Abstract

See full text

An earphone including a case, a case extension unit, a plate, a cover, a first speaker and a second speaker is provided. The first speaker is disposed on a supporting portion of the plate and is disposed on a first plane different from a second plane where the second speaker is located. A distance exits in the position of the first speaker and the position of the second speaker corresponding to a direction of the sound from the earphone to the user who wears the earphone. The distance variation can make the sound field have more special effects and have better frequency response in some frequency domain. The distance variation can also avoid the interference of different sound fields generated by the speakers inside the earphone, and thus improves the performance of the whole sound field.
