EARPHONE WITH MUTUALLY OBLIQUELY ORIENTED SOUND HOLES

摘要

An exemplary earphone includes a shell and a speaker mounted in the shell. The speaker divides a sound cavity of the shell into a front chamber at a front side of the speaker and a rear chamber at a rear side of the speaker. The shell includes a front wall confronting the speaker and a side wall extending obliquely from an edge of the front wall to the speaker. A first sound hole is defined in the front wall to communicate the front chamber of the shell with outer environment. A second sound hole is defined in the side wall to communicate the front chamber of the shell with outer environment. When the earphone is in use, the first sound hole is corresponding to a concha of human ear and the second sound hole is corresponding to an entrance of an external auditory meatus of human ear.
